Ocera Therapeutics, Inc.

Notes to Condensed Consolidated Financial Statements

1. The Company

Ocera Therapeutics, Inc. (the "Company") is a clinical-stage biopharmaceutical company focused on the development and commercialization of OCR-002 (ornithine phenylacetate). OCR-002 is an ammonia scavenger which has been granted orphan drug designation and Fast Track status by the U.S. Food and Drug Administration for the treatment of hyperammonemia and resultant hepatic encephalopathy in patients with liver cirrhosis, acute liver failure and acute-on-chronic liver disease.

On July 15, 2013, Terrapin Acquisition, Inc., a Delaware corporation (“Merger Sub”), a wholly owned subsidiary of Tranzyme, Inc., a Delaware corporation (“Tranzyme”), completed its merger (the “Merger”) with and into Ocera Therapeutics, Inc., a private Delaware corporation (“Private Ocera”).  Private Ocera was considered the acquiring company in the Merger for accounting purposes.  In connection with the Merger, the combined company changed its name to Ocera Therapeutics, Inc. and the name of Private Ocera was changed to Ocera Subsidiary, Inc. (“Ocera Subsidiary”).

The Company's business is subject to significant risks consistent with biopharmaceutical companies seeking to develop technologies and product candidates for human therapeutic use. These risks include, but are not limited to, uncertainties regarding research and development, access to capital, obtaining and enforcing patents, receiving regulatory approval and competition with other biotechnology and pharmaceutical companies.

The Company has a limited operating history and the sales and income potential of the Company's business and market are unproven. As of September 30, 2016, the Company has incurred losses since inception of $153.2 million. The Company anticipates that it will continue to incur net losses into the foreseeable future as it continues its efforts to develop and commercialize OCR-002 and as it expands its corporate infrastructure. Based on the Company's current operating plan, the Company believes its working capital is sufficient to fund its operations through at least the next twelve months.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company and its wholly-owned subsidiary have been prepared in accordance with United States of America generally accepted accounting principles ("U.S. GAAP") for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. This quarterly report should be read in conjunction with the consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2015.

Unaudited Interim Financial Information

The accompanying condensed consolidated financial statements and related disclosures are unaudited, have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

7

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Investments in Marketable Securities

All investments in marketable securities have been classified as "available-for-sale" and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. Unrealized gains and losses are excluded from earnings and are reported as a component of accumulated comprehensive income. Realized gains and losses and declines in fair value judged to be other than temporary, if any, on investments in marketable securities are included in interest and other income (expense), net. The cost of securities sold is based on the specific-identification method. Interest earned on investments in marketable securities is included in interest and other income.

Recent Accounting Pronouncements

Occasionally, new accounting standards are issued or proposed by the Financial Accounting Standards Board (the "FASB"), or other standards setting bodies that the Company adopts by the effective date specified within the standard. Unless otherwise discussed, standards that do not require adoption until a future date are not expected to have a material impact on the Company's condensed consolidated financial statements upon adoption.

Recent Accounting Updates Not Yet Effective

In August 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-15, Classification of Certain Cash Receipts and Cash Payments, which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815), Contingent Put and Call Options in Debt Instruments. This ASU clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. The new standard simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. This guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year in which the amendments are effective, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718), Compensation - Stock Compensation. The new guidance simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees' maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefit and employee taxes paid when an employer withholds shares for tax-withholding purposes. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The standard’s core principle is that a reporting entity will recognize revenue when it transfers promised goods or services to customers in an

8

amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard will become effective for the Company beginning in the first quarter of 2018. Early adoption is permitted in 2017. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. In March and April 2016, the FASB issued ASU 2016-08 Revenue From Contracts With Customers: Principal vs. Agent Considerations and ASU 2016-10 Revenue From Contracts with Customers: Identifying Performance Obligations and Licensing to provide supplemental adoption guidance and clarification to ASU 2014-09. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

3. Fair Value Measurements

Financial assets and liabilities are recorded at fair value. The carrying amounts of certain of the Company's financial instruments, including cash and cash equivalents, prepaid expenses and other current assets, accounts payable, and accrued liabilities and deferred revenue, approximate their fair value due to their short maturities. Short-term and long-term debt are reported at their respective amortized cost on its condensed consolidated balance sheets. The remaining financial instruments are reported on its condensed consolidated balance sheets at amounts that approximate current fair values. 

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis as of September 30, 2016, and December 31, 2015, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. As a basis for categorizing inputs, the Company uses a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value from market-based assumptions to entity specific assumptions:

Level 1: Inputs which include quoted prices in active markets for identical assets or liabilities;

Level 2: Inputs, other than level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level 3: Unobservable inputs that are supported by little or no market activity, which require the reporting entity to develop its own assumptions.

None of the Company’s non-financial assets and liabilities are recorded at fair value on a non-recurring basis. No transfers between fair value hierarchy levels have occurred during the periods presented.

Assets measured at fair value on a recurring basis as of September 30, 2016 consisted of the following (in thousands):

	Balance as of September 30, 2016		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Money market funds	$	28,599	$	28,599	$	—	$	—
Commercial paper	1,493		—		1,493		—
Corporate debt securities	3,008		—		3,008		—
	$	33,100	$	28,599	$	4,501	$	—

Assets measured at fair value on a recurring basis as of December 31, 2015 consisted of the following (in thousands):

	Balance as of December 31, 2015		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Money market funds	$	34,806	$	34,806	$	—	$	—
Corporate debt securities	7,415		—		7,415		—
	$	42,221	$	34,806	$	7,415	$	—

9

The Company estimates the fair value of commercial paper and corporate debt securities by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker quotes on the same or similar securities; issuer credit spreads; benchmark securities; prepayment or default projections based on historical data; and other observable inputs.

The estimated fair value of the Company's notes payable, considering level 2 inputs, approximates their carrying value based upon the borrowing terms and conditions currently available to the Company.    

4. Balance Sheet Components

Investments in Marketable Securities

The following table summarizes the Company's available for sale investments as of September 30, 2016(in thousands):

	Maturity (in years)	Amortized Cost		Unrealized Gains		Unrealized Losses			Estimated Fair Value
Short-term investments:
Commercial paper	1 or less	$	1,493	$	—	$	—		$	1,493
Corporate debt securities	1 or less	1,757		—		(1		)	1,756
Total short-term investments		$	3,250	$	—	$	(1	)	$	3,249

The following table summarizes the Company's available for sale investments as of December 31, 2015 (in thousands):

	Maturity (in years)	Amortized Cost		Unrealized Gains		Unrealized Losses			Estimated Fair Value
Short-term investments:
Corporate debt securities	1 or less	$	7,420	$	—	$	(5	)	$	7,415
Total short-term investments		$	7,420	$	—	$	(5	)	$	7,415

At each reporting date, the Company reviews its investments for impairment to determine if unrealized losses are other-than-temporary. For debt securities, management determines whether it intends to sell the impaired securities, and if there is no intent or expected requirement to sell, management considers whether it is likely that the amortized cost will be recovered. The Company does not consider unrealized losses on its debt investment securities to be credit-related. These unrealized losses relate to changes in interest rates and market spreads subsequent to purchase. The Company has not made a decision to sell securities with unrealized losses and believes it is more likely than not that it would not be required to sell such securities before recovery of its amortized cost. There have been no other-than-temporary losses recognized in earnings in any of the periods presented.

Accrued Liabilities

Accrued liabilities consisted of the following (in thousands):

	September 30,		December 31,
	2016		2015
Clinical trials	$	2,152	$	1,666
Compensation and related expenses	832		993
Professional services	194		319
Interest expense and other	77		155
Total accrued liabilities	$	3,255	$	3,133

5. Notes Payable

10

On July 30, 2015, the Company and Ocera Subsidiary entered into a Loan and Security Agreement (the “Loan Agreement”) with Oxford Finance LLC (“Oxford”) and Silicon Valley Bank (“SVB”) (collectively, the “Lenders”). The Loan Agreement provides for up to $20.0 million in new term loans (the “Term Loan Facility”), $10.0 million of which was funded on July 30, 2015. The remaining $10.0 million is available for draw until December 31, 2016 at the Company’s discretion, subject to achievement of certain financial and clinical milestones. The milestones will be satisfied if the Company (a) has raised proceeds of at least $15.0 million from the sale of equity securities or upfront payments from a partnership agreement and (b) achieved positive data from its ongoing Phase 2b clinical trial of OCR-002.

The annual interest rate for the initial $10.0 million funding is 8.275%, and the interest rate for the second tranche will be fixed upon drawdown at an annual rate that is greater of 8.275% or 8.085% plus the 30-day U.S. LIBOR rate. Loan payments are interest-only until February 1, 2017, followed by 30 equal monthly payments of principal and interest through the scheduled maturity date of August 1, 2019 if the second tranche is not drawn. If the second tranche is drawn, the interest-only period continues to August 1, 2017, followed by 24 equal monthly payments. In addition, a final payment equal to 3% of the aggregate amount drawn will be due at maturity or on earlier repayment. If the Company prepays all or a portion of the loans, a prepayment fee of between 1% and 3% of the principal amount prepaid will also be due depending on the timing of the prepayment.

At the initial funding, the Company received net proceeds of $9.7 million after fees and expenses. These fees and expenses are being accounted for as a debt discount and classified within notes payable on the Company’s condensed consolidated balance sheet. Legal and consulting fees are presented in the condensed consolidated balance sheet as a direct deduction from the carrying amount of the notes liability, consistent with debt discounts. Debt discounts, issuance costs and the final payment are being amortized or accreted as interest expense over the term of the loan using the effective interest method.

In connection with the Loan Agreement, the Company issued the Lenders warrants to purchase an aggregate of 97,680 shares of the Company's common stock at an exercise price of $4.095 per share. The Company recorded $0.3 million for the warrants as debt discount within notes payable and an increase to additional paid-in capital on the Company’s condensed consolidated balance sheet. As of September 30, 2016, the warrants remained outstanding and exercisable. The debt discount is being amortized as interest expense over the term of the Term Loan Facility using the effective interest method.

The Term Loan Facility is secured by substantially all of the assets of the Company and its subsidiaries, except that the collateral does not include any intellectual property held by the Company or its subsidiary. However, the Company has agreed not to encumber any of the intellectual property of the Company or its subsidiary. The Loan Agreement contains customary representations, warranties and covenants by the Company, and customary indemnification obligations and events of default. The Company was in compliance with all covenants set forth in the Loan Agreement as of September 30, 2016.

The Company recorded interest expense related to the Term Loan Facility of $0.3 million for the three months ended September 30, 2016, and $0.8 million for the nine months ended September 30, 2016. The Company recorded $0.2 million of interest expense for the three and the nine months ended September 30, 2015. The annual effective interest rate on the note payable, including the amortization of the debt discounts and accretion of the final payments, is 11.72%.

Future minimum payments under the Loan Agreement as of September 30, 2016 are as follows (in thousands):

Years ending December 31:
2016 (remaining three months)	$	207

6. Stockholders' Equity

On May 15, 2015, the Company entered into a sales agreement (the “Sales Agreement”) with Cowen and Company, LLC (“Cowen”), pursuant to which the Company may issue and sell shares of its common stock having

11

aggregate sales proceeds of up to $25.0 million from time to time through an “at the market” equity program under which Cowen acts as sales agent.

During the nine months ended September 30, 2016, the Company sold an aggregate of 2,340,980 shares of common stock under the Sales Agreement, at an average price of approximately $2.68 per share, for gross proceeds of $6.3 million and net proceeds of $6.0 million after deducting commissions and other transactions costs. During the nine months ended September 30, 2015, proceeds from issuance of common stock under the Sales Agreement were $2.5 million after deducting commissions and other transaction costs.

As of September 30, 2016, $15.0 million of common stock remained available to be sold under the Sales Agreement, subject to certain conditions specified therein.

In September 2016, the Company issued 15,753 shares of common stock pursuant to the cashless exercise of certain warrants at an exercise price of $0.67 price per share.

7. Stock-Based Compensation

The Company’s stock option awards activity and related information for the nine months ended September 30, 2016 were as follows (in thousands, except share and per share data):

							Weighted-avg.
	Shares				Weighted-avg.		Remaining	Aggregate
	Available		Stock Options		Exercise Price		Contractual	Intrinsic

Exercisable			1,532,114		$	7.16	6.48	$	187

The aggregate intrinsic value of options exercised under all option plans was $42,000 for the nine months ended September 30, 2016 determined as of the date of option exercise. No options were exercised during the nine months ended September 30, 2015.

The Company recognized stock-based compensation expense within the condensed consolidated statements of operations and comprehensive loss as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2016		2015		2016		2015
Research and development	$	139	$	192	$	516	$	456
General and administrative	864		766		2,652		2,404
Total	$	1,003	$	958	$	3,168	$	2,860

At September 30, 2016, there were 111,000 unvested options outstanding with performance conditions related to the achievement of certain clinical milestones. During the three and nine months ended September 30, 2016, stock-based compensation expense recorded for theses performance-based options was insignificant to the interim condensed consolidated financial statements.

12

In April 2016, the Company’s board of directors approved an amendment and restatement of the Company’s Fourth Amended and Restated 2011 Stock Option and Incentive Plan (the “2011 Plan”) to, among other things, increase the maximum number of shares that may be issued under the 2011 Plan from 3,602,328 to 5,002,328 shares. The amendment and restatement of the 2011 Plan was approved by the Company’s stockholders on June 14, 2016.

As of September 30, 2016, there was unrecognized stock-based compensation expense of $6.2 million related to stock options. The Company expects to recognize those costs over a weighted average period of 2.16 years.

Stock-based compensation expense for stock options is estimated at the grant date based on the fair value using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of all stock options granted was estimated using the following ranges of weighted-average assumptions:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2016	2015	2016	2015
Expected dividend yield	—	—	—	—
Risk-free interest rates	0.59% - 1.39%	1.59% - 1.64%	0.59% - 1.97%	1.52% - 2.08%
Expected term in years	0.95 - 4.43	5.52 - 6.08	0.95 - 8.14	5.49 - 8.06
Expected volatility	73% - 87%	78% - 80%	73% - 94%	78% - 92%

On January 6, 2016, the Company granted certain of its executive officers non-qualified stock options to purchase 206,625 shares of the Company’s common stock that vest on a monthly basis in equal installments over 48 months following the grant date if the Company's stock price equals or exceeds $6.00 for 20 consecutive trading days on or before June 30, 2017. The options expire ten years from the date of the grant.

The fair values of these options were determined using a Monte Carlo simulation model incorporating the following ranges of weighted-average assumptions:

	Nine Months Ended September 30, 2016
Expected dividend yield	—
Risk-free interest rates	1.82% - 2.05%
Expected term in years	6.02 - 8.00
Expected volatility	77% - 89%
Weighted-average fair value per share	1.33 - 1.42

The estimated expense for these awards is being recognized on an accelerated basis over the estimated requisite service period, with no adjustments in the future periods based upon the Company's actual common stock price. The Company recorded $0.1 million in stock-based compensation expense during the nine months ended September 30, 2016 in connection with such awards. Stock-based compensation expense related to these awards was insignificant during the three months ended September 30, 2016.

8. Discontinued Operations

On September 11, 2013, the Company announced a restructuring plan related to the operations of Tranzyme Pharma Inc. (“Tranzyme Pharma”). On December 13, 2013, the Company entered into a Technology Transfer and License Agreement with Genentech, Inc. ("Genentech"), and F. Hoffman-La Roche, Ltd. ("Roche") to sell certain Canadian fixed assets and materials, the MATCH technology and rights to the Genentech and Roche customer agreements and related intellectual property through licensing of patents for $4.0 million. The Company concluded that the operations of Tranzyme Pharma and related asset groups sold to Genentech and Roche would be accounted for as discontinued operations as the operations and cash flows of the discontinued component or asset group would be eliminated from ongoing operations of the Company and there would not be significant involvement in the component or asset group after the disposal transaction.

13

In 2014, the Company completed its obligations under the Technology Transfer and License Agreement with Genentech and Roche and recognized a gain on disposal of assets of $1.1 million within discontinued operations. There was $0.2 million in income recorded in discontinued operations for the three and nine months ended September 30, 2015 that relates to certain foreign research credits received.

9. Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. Potentially dilutive securities which include warrants and outstanding stock options have been excluded from the computation of diluted net loss per share as the effect of their inclusion would be anti-dilutive. For all periods presented, diluted and basic net loss per share were identical due to the Company’s net loss position.

The following table presents the computation of net loss per share (in thousands, except share and per share data):

	Three Months Ended September 30,						Nine Months Ended September 30,
	2016			2015			2016			2015
Numerator
Net loss from continuing operations	$	(7,125	)	$	(6,793	)	$	(21,742	)	$	(19,666	)

Net loss per share	$	(0.32	)	$	(0.33	)	$	(1.01	)	$	(0.98	)

The following weighted average outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share of common stock for the periods presented as the effect of their inclusion would have been anti-dilutive:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2016	2015	2016	2015
Common stock warrants	1,021,651	997,839	1,024,705	954,345
Common stock options	3,646,426	2,340,054	3,652,762	2,134,428
Total	4,668,077	3,337,893	4,677,467	3,088,773

The Company has utilized the control number concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is loss from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. Therefore, no dilutive effect has been recognized in the calculation of income from discontinued operations per share for the three and nine months ended September 30, 2015.

10. Subsequent Events

Pursuant to the Company's "at the market" equity program, since September 30, 2016,the Company has sold an aggregate of 68,107 shares of common stock under the Sales Agreement at an average price of approximately $2.60 per share for gross proceeds of approximately $0.2 million.

14

In September 2014, the Company entered into an asset license and purchase agreement for the sale and license of ulimorelin (the “Lyric Agreement”), the former lead compound of Tranzyme, to Lyric Pharmaceuticals, Inc. (“Lyric”).  In October 2016, Lyric achieved a milestone under the Lyric Agreement, and accordingly, the Company will record $0.1 million in related milestone revenue during the fourth quarter of 2016.

In October 2016, the Company assigned its rights to certain non-core intellectual property acquired in the Merger with Tranzyme to GE Healthcare Dharmacon, Inc. (“GE”), formerly known as Open Biosystems, Inc.  In connection with the assignment, the Company’s existing license and marketing agreement with GE terminated and all future royalty payments payable from GE to the Company will cease.  In consideration for the assignment, the Company will receive a one-time payment of $0.5 million from GE.

Item 2. Management’sDiscussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 and the unaudited consolidated financial statements and notes thereto included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements that involve significant risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” in Part II, Item 1 of this Quarterly Report on Form 10-Q, Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2015 and our other filings with the SEC, our actual results could differ materially from those anticipated in these forward-looking statements. Except as required by law, we assume no obligation to update these forward-looking statements publicly, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future.

Overview

We are a clinical-stage biopharmaceutical company focused on acute and chronic orphan liver diseases. Our initial focus is on the development and commercialization of a clinical candidate, OCR-002, for the treatment of hepatic encephalopathy, or HE. HE is a serious complication of liver cirrhosis, or liver failure, marked by mental changes including confusion, impaired motor skills, disorientation in time and space, and, in its more severe form, stupor, coma and even death. Although the exact cause of HE is not completely understood, there is growing evidence that elevated ammonia is a primary driver of HE, and that lowering ammonia may be beneficial to patients suffering from HE. Common causes of liver malfunction leading to elevated ammonia levels and HE include alcoholism, viral hepatitis and autoimmune diseases, non-alcoholic steatohepatitis, or NASH, as well as obesity, Type II diabetes, and acetaminophen overdose. It is estimated that in the United States there are approximately eight million individuals with some form of chronic liver disease, of which one million have cirrhosis. Of the one million individuals in the United States that have cirrhosis, it is estimated that approximately 500,000 are at risk for developing HE.

OCR-002 is a novel molecule, ornithine phenylacetate, which functions as an ammonia scavenger. In pre-clinical studies, OCR-002 significantly reduced arterial ammonia and cerebral edema in an animal model of chronic liver disease and significantly attenuated arterial ammonia, extracellular brain ammonia and intracranial pressure in a second animal model of acute liver failure.

We are currently conducting a randomized, placebo-controlled double blind Phase 2b clinical trial to evaluate the safety and efficacy of intravenous administration of OCR-002 in reducing the severity of HE symptoms among hospitalized HE patients. In March 2015, an independent data monitoring committee, or DMC, conducted an interim analysis, reporting that the trial was not futile and that no clinically significant safety concerns were observed. In addition, the DMC recommended that we continue the trial and increase target enrollment from 140 patients to approximately 230 patients. This sample size recommendation allows the trial to maintain 80% statistical power to observe the treatment effect at the conclusion of the trial that was observed by the DMC at the time of the interim analysis. The trial is currently being conducted in approximately 100 sites worldwide and as of October 31, 2016, over 220 patients have been enrolled in total. We expect to complete enrollment in the fourth quarter of 2016 and announce topline data in the first quarter of 2017.

We are also developing an oral form of OCR-002 with the goal of providing continuity of care for HE patients post discharge in order to prevent subsequent episodes of acute HE. In the fourth quarter of 2015, we completed a Phase 1 clinical trial with oral formulations of OCR-002 in healthy subjects. This open label, single-dose, five treatment, five-period crossover trial evaluated the pharmacokinetic, or pK, safety and tolerability of three prototype, extended-release oral formulations of OCR-002 compared to an immediate release oral solution of OCR-002 and the FDA approved ammonia-lowering agent, glycerol phenylbutyrate (RAVICTI®). Glycerol phenylbutyrate is a pre-pro-drug of phenylacetate, or PAA, a component of OCR-002. The results of this trial demonstrated a robust, extended-release pattern for all three pilot OCR-002 extended-release formulations, with mean plasma phenylacetate concentrations exceeding those achieved with

15

RAVICTI® at all time points for at least 12 hours post-dose. In addition, the concentration of phenylacetylglutamine, or PAGN, the end-product responsible for clearing ammonia, was greater in both plasma and urine for all three OCR-002 extended-release dosage forms than RAVICTI® at an approximately equivalent molar PAA dose. Based on the strength of these results and the prior clinical proof of concept established with RAVICTI® in preventing recurrent HE in patients suffering from liver cirrhosis and a prior history of HE, we plan to continue development of oral OCR-002. In September 2016 we initiated part one of a two-part Phase 1 clinical trial in patients with cirrhosis. Part 1 will evaluate the pK and bioavailability of a single oral dose of OCR-002 in cirrhotic patients dosed under certain conditions. Part 2 is expected to be a multi-dose study which will include the evaluation of steady state pK and the formation of PAGN. Data from Part 1 of this study is expected to be available by year-end 2016. We expect to complete Part 2 of this study, with data available, in the first half of 2017.

In 2012, we completed a Phase 1 pK and safety clinical trial of the intravenous form of OCR-002. A Phase 2a investigator-sponsored trial in Spain evaluated OCR-002 in patients with upper gastrointestinal bleeding associated with liver cirrhosis. These patients tend to have elevated ammonia levels because they swallow blood, which produces more ammonia as it is digested. In the first part of this trial, a 10-patient open label safety cohort, OCR-002 was shown to lower ammonia when administered as a continuous intravenous infusion of up to 10 grams per 24 hours. In February 2015, we announced the preliminary topline results of the second part of this trial, which was a randomized, placebo-controlled cohort of 38 patients. The data showed that over the first 12 hours of dosing, OCR-002 lowered ammonia by 19.6% compared to 3.2% in the placebo group, but this difference did not reach statistical significance. A statistically significant difference in urinary excretion of ammonia, as measured by PAGN, was observed and OCR-002 demonstrated a favorable safety profile and appeared to be well tolerated.

In addition, the investigator-sponsored Phase 2a clinical trial conducted by the National Institutes of Health, or NIH, to evaluate the safety and pK of OCR-002 in patients with hyperammonemia and HE due to acute liver failure or injury, was completed in September 2016. In November 2015, the NIH announced preliminary pK data on 24 patients and concluded that OCR-002 was safe and well-tolerated at the levels administered, up to 10 grams per 24 hours. A correlation was observed between the doses administered and the drug levels seen in the blood, but even at the 10 gram dose, the investigators deemed the exposure of the drug to be below the desired range. In September 2016, the NIH completed enrollment of an additional 12 patients at a higher dose of 20 grams per 24 hours. No drug-related serious adverse events were observed in this study and all doses were well tolerated. In addition, therapeutic serum levels of PAA were achieved at infusion rates of OCR-00 20g/24hrs, resulting in considerable ammonia excretion in urine as PAGN, even in patients with non-oliguric renal failure. Additional data from this study is expected to be available by the end of 2016.

Our strategy is to focus clinical development activities on the intravenous form of OCR-002 to treat acute HE in hospitalized patients and on the oral form of OCR-002, which will be directed to chronic care of HE patients.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate our estimates and judgments related to each of our critical accounting areas. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We discussed accounting policies and assumptions that involve a higher degree of judgment and complexity within our Annual Report on Form 10-K for the year ended December 31, 2015. For the nine months ended September 30, 2016, there have been no material changes to our critical accounting policies and estimates as disclosed in our Annual Report on Form 10-K.

Merger with Tranzyme, Inc.

On July 15, 2013, Terrapin Acquisition, Inc., a Delaware corporation and wholly owned subsidiary of Tranzyme, Inc., a Delaware corporation, or Tranzyme, completed its merger, or the Merger, with and into Ocera Therapeutics, Inc., a private Delaware corporation, or Private Ocera.  Private Ocera is considered the acquiring company in the Merger for accounting purposes. In connection with the Merger, the combined company changed its name to Ocera Therapeutics, Inc. and the name of Private Ocera was changed to Ocera Subsidiary, Inc., or Ocera Subsidiary.

Revenues

We generated $38,000 in royalty revenue for the three months ended September 30, 2016compared to$35,000in royalty revenue for the three months ended September 30, 2015. We generated$97,000 in revenue for the nine months ended September 30, 2016compared to$109,000in revenue for the nine months ended September 30, 2015.The revenue in all periods was attributable to a license agreement that we acquired from Tranzyme in connection with the Merger.

Costs and Expenses

Research and Development Expenses

Research and development expenses increased marginally during the three months ended September 30, 2016 when compared with the same period in 2015. Research and development expense increased by $0.9 million, during the nine months ended September 30, 2016, as compared to the same period ended in September 30, 2015. The increase was primarily driven by an increase in headcount and related costs.

Expenses related to clinical trials are based on estimates of patient enrollment and related expenses at clinical investigator sites as well as estimates for the services received and efforts expended pursuant to contracts with multiple research institutions and contract research organizations that may be used to conduct and manage clinical trials on our behalf. We generally accrue expenses related to clinical trials based on contracted amounts applied to the level of patient enrollment and activity. If timelines or contracts are modified based upon changes in the clinical trial protocol or scope of work to be performed, we modify our estimates of accrued expenses accordingly on a prospective basis.

Due to the significant risks and uncertainties inherent in the clinical development and regulatory approval processes, we cannot reasonably estimate the cost to complete projects and development timelines for their completion. Enrollment in clinical trials might be delayed or occur faster than anticipated for reasons beyond our control, requiring additional cost and time or accelerating spending. Results from clinical trials might not be favorable, or might require us to perform additional unplanned clinical trials, accelerating spending, requiring additional cost and time, or resulting in termination of the project. Regulatory reviews can also be delayed. Process development and manufacturing scale-up for production of clinical and commercial product supplies might take longer and cost more than our forecasts. As a result, clinical development and regulatory programs are subject to risks and changes that might significantly impact cost projections and timelines. We will need to raise significant additional capital to advance the development and commercialization of OCR-002, which may include entering into strategic alliances.

General and Administrative Expenses

Our general and administrative expenses increased by $0.2 million and $0.7 million during the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The increases were primarily due to increased personnel-related costs, including stock-based compensation expense, as well as costs associated with professional services fees.

17

We expect that general and administrative expenses may increase in the future as we expand our operating activities, maintain and expand our patent portfolio and potentially expand our infrastructure.

Other Income (Expense)

Our net other expense increased by $0.1 million and $0.6 million for the three and nine months ended September 30, 2016, respectively, as compared to the same periods in 2015. The increases were primarily due to increases in interest expense and amortization of debt issuance costs related to the debt facility that closed in the third quarter of 2015.

Net income from discontinued operations

During the three and nine months ended September 30, 2015, $0.2 million of income was recorded within discontinued operations. This related to certain foreign research credits received in the third quarter 2015.

Liquidity and Capital Resources

Cash Flows

The following table summarizes our cash flows for the nine months ended September 30, 2016 and 2015 (in thousands):

	Nine Months Ended September 30,

Investing activities	4,127			15,543
Financing activities	6,022			12,228
Net decrease in cash and cash equivalents	$	(6,706	)	$	12,640

Comparison of the Nine Months Ended September 30, 2016 and 2015

Cash used in continuing operating activities for the nine months ended September 30, 2016 was attributable to our net loss from operations of $21.7 million partially offset by changes in operating assets and liabilities of $1.5 million and non-cash charges of $3.4 million including stock-based compensation expense, accretion of premiums on investment in marketable securities and amortization of debt discount. Cash used in continuing operating activities for the nine months ended September 30, 2015 was attributable to our net loss from continuing operations of $19.7 million partially offset by changes in operating assets and liabilities of $1.0 million and non-cash charges of $3.4 million including stock-based compensation expense and accretion of premium on investment of securities.

Cash provided by discontinued operating activities for the nine months ended September 30, 2015 primarily reflected certain foreign research credits received.

Debt Facility

On July 30, 2015, we entered into a Loan and Security Agreement, or the Loan Agreement, with Oxford Finance LLC and Silicon Valley Bank, or collectively, the Lenders. The Loan Agreement provides up to $20 million principal in new term loans, $10 million of which was funded on July 30, 2015. The remaining $10 million is available for draw until December 31,

18

2016 at the Company’s discretion, subject to achievement of certain financial and clinical milestones. We refer to this facility as the Term Loan Facility.

The term loan repayment schedule provides for interest only payments (i) through either February 1, 2017 or August 1, 2017 with respect to the first $10 million of the term loans, depending on whether the remaining term loans have been funded within a certain period set forth in the Loan Agreement, and (ii) through August 1, 2017 with respect to the remaining $10 million of term loans, in each case followed by consecutive equal monthly payments of principal and interest in arrears starting on such dates and continuing through the maturity date of August 1, 2019. The Loan Agreement provides for an interest rate equal to the greater of (i) 8.275% or (ii) the sum of the thirty-day U.S. LIBOR rate for five days prior to the funding date of the applicable term loan plus 8.085%. The Loan Agreement also provides for a final interest payment equal to 3.0% of the original principal amount of the first $10 million in term loans and 1.325% of the original principal amount of the remaining $10 million in term loans, or $432,500, which is due when the term loan becomes due or upon the prepayment of the facility. We have the option to prepay the outstanding balance of the term loan in full, subject to a prepayment fee of 1% to 3% depending upon when the prepayment occurs. The Term Loan Facility matures on August 1, 2019.

The Term Loan Facility is secured by substantially all of our assets and the assets of Ocera Subsidiary, Inc., except that the collateral does not include any intellectual property held by us or Ocera Subsidiary. However, pursuant to the terms of a negative pledge arrangement, we have agreed not to encumber any of the intellectual property of ours or our subsidiary. The Loan Agreement contains customary representations, warranties and covenants by us, which covenants limit our ability to convey, sell, lease, transfer, assign or otherwise dispose of certain of our assets; engage in any business other than the businesses we currently engage in or reasonably related thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay dividends and make certain other restricted payments; make certain investments; enter into any material transactions with any affiliates, with certain exceptions; make payments on any subordinated debt; and permit certain of our subsidiaries to maintain, own or otherwise hold any material assets or conduct any business operations other than as disclosed to the Lenders. In addition, subject to certain exceptions, we and Ocera Subsidiary are required to maintain with Silicon Valley Bank their respective primary deposit accounts, securities accounts and commodity accounts.

The Loan Agreement also contains customary indemnification obligations and customary events of default, including, among other things, our failure to fulfill certain of our obligations under the Loan Agreement, the occurrence of a material adverse change, which is defined as a material adverse change in our business, operations, or condition (financial or otherwise), a material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority of the Lenders’ lien in the collateral or in the value of such collateral. In the event of default by us under the Loan Agreement, the Lenders would be entitled to exercise their remedies thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding under the Loan Agreement, which could harm our financial condition.

Capital Resources and Funding Requirements

We will require significant additional funds to support future operations including our development activities associated with the intravenous and oral formulations of OCR-002. Our future funding requirements depend on many factors, including, but not limited to the progress, timing, scope and costs of our nonclinical studies and clinical trials including the ability to enroll patients on a timely basis in our planned and potential future clinical trials, the time and cost necessary to respond to technological, market or governmental developments, the cost of manufacturing adequate supplies of drug substance and drug product and the cost of filing, prosecuting, defending and enforcing any patent claims or other intellectual property rights.

We expect to fund our operations with our current cash and cash equivalents and proceeds from potential additional financing transactions and possible strategic opportunities. We believe that our current cash and cash equivalents will be sufficient to fund our operations for at least the next twelve months.

On May 15, 2015, we filed a shelf registration statement on Form S-3 under which we may offer shares of our common stock and preferred stock, various series of warrants to purchase common stock or preferred stock and debt securities, either individually or in units, in one or more offerings, up to a total dollar amount of $150.0 million. On May 15, 2015, we entered into a sales agreement, or the Sales Agreement, with Cowen and Company, LLC, or Cowen, pursuant to which we may issue and sell shares of our common stock for which we included a prospectus to our shelf registration statement on Form S-3, having aggregate sales proceeds of up to $25.0 million from time to time, through an “at the market” equity program under which Cowen acts as sales agent. During the nine month period ended September 30, 2016, we sold an aggregate of 2,340,980 shares of common stock under the Sales Agreement, at an average sale price of approximately $2.68 per share for gross proceeds of $6.3 million and net proceeds of $6.0 million after deducting

19

commissions and other transaction costs. As of September 30, 2016, $15.0 million of common stock remained available to be sold under the Sales Agreement, subject to certain conditions specified therein.

We have based our estimates of our cash needs on a number of assumptions that may prove to be wrong, and changing circumstances beyond our control may cause us to consume capital more rapidly than we currently anticipate. For example, our OCR-002 Phase 2b clinical trial may cost more than we expect, or development of the oral formulation of OCR-002 may involve the license of proprietary technology. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidate, we are unable to estimate the amounts of increased capital outlays and operating expenditures associated with our current and anticipated clinical trials. If adequate funds are not available to us on a timely basis, or at all, we may be required to terminate or delay clinical trials or other development activities for OCR-002.

Our ability to finance operations beyond our current resources will depend heavily on our ability to fully and timely enroll patients and obtain favorable results in clinical trials of OCR-002 and to develop and commercialize OCR-002 successfully. For example, we may not access the second tranche of the Term Loan Facility unless we satisfy the following milestones by December 31, 2016: (a) we have raised proceeds of at least $15.0 million from the sale of equity securities or upfront payments from a partnership agreement and (b) we have achieve positive data from its ongoing Phase 2b clinical trial of OCR-002. Based on our current projections, we do not expect to have topline data from our Phase 2b clinical trial of OCR-002 until the first quarter of 2017. As a result, unless the Term Loan Facility is amended, we may not be able to access the $10.0 million second tranche.

Additional financing may not be available when we need it or may not be available on terms that are favorable to us. We may elect to raise additional funds even before we need them if the conditions for raising capital are favorable. We may seek to raise additional capital through a combination of private and public equity offerings and debt financings. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of existing stockholders will be diluted, and the terms may include liquidation or other preferences that adversely affect the rights of existing stockholders. Debt financing, as is the case with our Term Loan Facility, results in increased fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions such as incurring debt, making capital expenditures or declaring dividends.

Contractual Obligations

The following table summarizes our future contractual obligations as of September 30, 2016(in thousands):

	Payments due by period
	Less than 1 year		1 to 3 years		3 to 5 years		More than 5 years		Total
Note payable obligations, including interest (1)	$	207	$	8,281	$	3,261	$	—	$	11,749
Operating lease obligations	$	111	$	325	$	8	$	—	$	444
Other non-cancellable commitments (2)	$	218	$	—	$	—	$	—	$	218
Total	$	536	$	8,606	$	3,269	$	—	$	12,411

(1)    Upon the occurrence of an event of default, as defined in the Loan Agreement, and during the continuance of an event of default, a default interest rate of an additional 5% will be applied to the outstanding loan balances, and the Lenders may declare all outstanding obligations immediately due and payable.

(2)     Contractual obligations and commitments under clinical contracts that are non-cancellable.

We have license milestone obligation payments that are not included in the table above because the Company cannot determine when or if the payments will occur. In the normal course of business, we enter into various firm purchase commitments and other contractual obligations which are cancellable within ninety days or less and are not a part of the future contractual obligations table above.

Off-Balance Sheet Arrangements

We do not currently have, and did not have during the periods presented, any off-balance sheet arrangements, as defined under the SEC rules.

Item 3.Quantitative and Qualitative Disclosures About Market Risk

For quantitative and qualitative disclosures about market risk affecting our company, see Item 7A: "Quantitative and Qualitative Disclosures about Market Risk" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

Item 4.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act) that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our principal executive officer and principal financial and accounting officer, evaluated the effectiveness of our disclosure controls and procedures as of the period covered by this report. Based on that evaluation, our principal executive officer and principal financial and accounting officer concluded that, as of September 30, 2016, our disclosure controls and procedures were effective at the reasonable assurance level.

We continue to review and document our disclosure controls and procedures, including our internal controls and procedures for financial reporting, and may from time to time make changes aimed at enhancing their effectiveness and to ensure that our systems evolve with our business.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f) under the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1.Legal Proceedings

The Company

The Company

Ocera Therapeutics, Inc. (the "Company") is a clinical-stage biopharmaceutical company focused on the development and commercialization of OCR-002 (ornithine phenylacetate). OCR-002 is an ammonia scavenger which has been granted orphan drug designation and Fast Track status by the U.S. Food and Drug Administration for the treatment of hyperammonemia and resultant hepatic encephalopathy in patients with liver cirrhosis, acute liver failure and acute-on-chronic liver disease.

On July 15, 2013, Terrapin Acquisition, Inc., a Delaware corporation (“Merger Sub”), a wholly owned subsidiary of Tranzyme, Inc., a Delaware corporation (“Tranzyme”), completed its merger (the “Merger”) with and into Ocera Therapeutics, Inc., a private Delaware corporation (“Private Ocera”).  Private Ocera was considered the acquiring company in the Merger for accounting purposes.  In connection with the Merger, the combined company changed its name to Ocera Therapeutics, Inc. and the name of Private Ocera was changed to Ocera Subsidiary, Inc. (“Ocera Subsidiary”).

The Company's business is subject to significant risks consistent with biopharmaceutical companies seeking to develop technologies and product candidates for human therapeutic use. These risks include, but are not limited to, uncertainties regarding research and development, access to capital, obtaining and enforcing patents, receiving regulatory approval and competition with other biotechnology and pharmaceutical companies.

The Company has a limited operating history and the sales and income potential of the Company's business and market are unproven. As of September 30, 2016, the Company has incurred losses since inception of $153.2 million. The Company anticipates that it will continue to incur net losses into the foreseeable future as it continues its efforts to develop and commercialize OCR-002 and as it expands its corporate infrastructure. Based on the Company's current operating plan, the Company believes its working capital is sufficient to fund its operations through at least the next twelve months.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company and its wholly-owned subsidiary have been prepared in accordance with United States of America generally accepted accounting principles ("U.S. GAAP") for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. This quarterly report should be read in conjunction with the consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2015.

Unaudited Interim Financial Information

The accompanying condensed consolidated financial statements and related disclosures are unaudited, have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Investments in Marketable Securities

All investments in marketable securities have been classified as "available-for-sale" and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. Unrealized gains and losses are excluded from earnings and are reported as a component of accumulated comprehensive income. Realized gains and losses and declines in fair value judged to be other than temporary, if any, on investments in marketable securities are included in interest and other income (expense), net. The cost of securities sold is based on the specific-identification method. Interest earned on investments in marketable securities is included in interest and other income.

Recent Accounting Pronouncements

Occasionally, new accounting standards are issued or proposed by the Financial Accounting Standards Board (the "FASB"), or other standards setting bodies that the Company adopts by the effective date specified within the standard. Unless otherwise discussed, standards that do not require adoption until a future date are not expected to have a material impact on the Company's condensed consolidated financial statements upon adoption.

Recent Accounting Updates Not Yet Effective

In August 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-15, Classification of Certain Cash Receipts and Cash Payments, which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815), Contingent Put and Call Options in Debt Instruments. This ASU clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. The new standard simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. This guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year in which the amendments are effective, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718), Compensation - Stock Compensation. The new guidance simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees' maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefit and employee taxes paid when an employer withholds shares for tax-withholding purposes. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The standard’s core principle is that a reporting entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard will become effective for the Company beginning in the first quarter of 2018. Early adoption is permitted in 2017. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. In March and April 2016, the FASB issued ASU 2016-08 Revenue From Contracts With Customers: Principal vs. Agent Considerations and ASU 2016-10 Revenue From Contracts with Customers: Identifying Performance Obligations and Licensing to provide supplemental adoption guidance and clarification to ASU 2014-09. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

Financial assets and liabilities are recorded at fair value. The carrying amounts of certain of the Company's financial instruments, including cash and cash equivalents, prepaid expenses and other current assets, accounts payable, and accrued liabilities and deferred revenue, approximate their fair value due to their short maturities. Short-term and long-term debt are reported at their respective amortized cost on its condensed consolidated balance sheets. The remaining financial instruments are reported on its condensed consolidated balance sheets at amounts that approximate current fair values. 

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis as of September 30, 2016, and December 31, 2015, and indicate the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value. As a basis for categorizing inputs, the Company uses a three-tier fair value hierarchy, which prioritizes the inputs used to measure fair value from market-based assumptions to entity specific assumptions:

Level 1: Inputs which include quoted prices in active markets for identical assets or liabilities;

Level 2: Inputs, other than level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level 3: Unobservable inputs that are supported by little or no market activity, which require the reporting entity to develop its own assumptions.

None of the Company’s non-financial assets and liabilities are recorded at fair value on a non-recurring basis. No transfers between fair value hierarchy levels have occurred during the periods presented.

Assets measured at fair value on a recurring basis as of September 30, 2016 consisted of the following (in thousands):

	Balance as of September 30, 2016		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Money market funds	$	28,599	$	28,599	$	—	$	—
Commercial paper	1,493		—		1,493		—
Corporate debt securities	3,008		—		3,008		—
	$	33,100	$	28,599	$	4,501	$	—

Assets measured at fair value on a recurring basis as of December 31, 2015 consisted of the following (in thousands):

	Balance as of December 31, 2015		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Money market funds	$	34,806	$	34,806	$	—	$	—
Corporate debt securities	7,415		—		7,415		—
	$	42,221	$	34,806	$	7,415	$	—

The Company estimates the fair value of commercial paper and corporate debt securities by taking into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. These inputs include reported trades of and broker quotes on the same or similar securities; issuer credit spreads; benchmark securities; prepayment or default projections based on historical data; and other observable inputs.

The estimated fair value of the Company's notes payable, considering level 2 inputs, approximates their carrying value based upon the borrowing terms and conditions currently available to the Company.

Total short-term investments		$	7,420	$	—	$	(5	)	$	7,415

At each reporting date, the Company reviews its investments for impairment to determine if unrealized losses are other-than-temporary. For debt securities, management determines whether it intends to sell the impaired securities, and if there is no intent or expected requirement to sell, management considers whether it is likely that the amortized cost will be recovered. The Company does not consider unrealized losses on its debt investment securities to be credit-related. These unrealized losses relate to changes in interest rates and market spreads subsequent to purchase. The Company has not made a decision to sell securities with unrealized losses and believes it is more likely than not that it would not be required to sell such securities before recovery of its amortized cost. There have been no other-than-temporary losses recognized in earnings in any of the periods presented.

Debt Disclosure [Abstract]

Notes Payable

Notes Payable

On July 30, 2015, the Company and Ocera Subsidiary entered into a Loan and Security Agreement (the “Loan Agreement”) with Oxford Finance LLC (“Oxford”) and Silicon Valley Bank (“SVB”) (collectively, the “Lenders”). The Loan Agreement provides for up to $20.0 million in new term loans (the “Term Loan Facility”), $10.0 million of which was funded on July 30, 2015. The remaining $10.0 million is available for draw until December 31, 2016 at the Company’s discretion, subject to achievement of certain financial and clinical milestones. The milestones will be satisfied if the Company (a) has raised proceeds of at least $15.0 million from the sale of equity securities or upfront payments from a partnership agreement and (b) achieved positive data from its ongoing Phase 2b clinical trial of OCR-002.

The annual interest rate for the initial $10.0 million funding is 8.275%, and the interest rate for the second tranche will be fixed upon drawdown at an annual rate that is greater of 8.275% or 8.085% plus the 30-day U.S. LIBOR rate. Loan payments are interest-only until February 1, 2017, followed by 30 equal monthly payments of principal and interest through the scheduled maturity date of August 1, 2019 if the second tranche is not drawn. If the second tranche is drawn, the interest-only period continues to August 1, 2017, followed by 24 equal monthly payments. In addition, a final payment equal to 3% of the aggregate amount drawn will be due at maturity or on earlier repayment. If the Company prepays all or a portion of the loans, a prepayment fee of between 1% and 3% of the principal amount prepaid will also be due depending on the timing of the prepayment.

At the initial funding, the Company received net proceeds of $9.7 million after fees and expenses. These fees and expenses are being accounted for as a debt discount and classified within notes payable on the Company’s condensed consolidated balance sheet. Legal and consulting fees are presented in the condensed consolidated balance sheet as a direct deduction from the carrying amount of the notes liability, consistent with debt discounts. Debt discounts, issuance costs and the final payment are being amortized or accreted as interest expense over the term of the loan using the effective interest method.

In connection with the Loan Agreement, the Company issued the Lenders warrants to purchase an aggregate of 97,680 shares of the Company's common stock at an exercise price of $4.095 per share. The Company recorded $0.3 million for the warrants as debt discount within notes payable and an increase to additional paid-in capital on the Company’s condensed consolidated balance sheet. As of September 30, 2016, the warrants remained outstanding and exercisable. The debt discount is being amortized as interest expense over the term of the Term Loan Facility using the effective interest method.

The Term Loan Facility is secured by substantially all of the assets of the Company and its subsidiaries, except that the collateral does not include any intellectual property held by the Company or its subsidiary. However, the Company has agreed not to encumber any of the intellectual property of the Company or its subsidiary. The Loan Agreement contains customary representations, warranties and covenants by the Company, and customary indemnification obligations and events of default. The Company was in compliance with all covenants set forth in the Loan Agreement as of September 30, 2016.

The Company recorded interest expense related to the Term Loan Facility of $0.3 million for the three months ended September 30, 2016, and $0.8 million for the nine months ended September 30, 2016. The Company recorded $0.2 million of interest expense for the three and the nine months ended September 30, 2015. The annual effective interest rate on the note payable, including the amortization of the debt discounts and accretion of the final payments, is 11.72%.

Future minimum payments under the Loan Agreement as of September 30, 2016 are as follows (in thousands):

Years ending December 31:
2016 (remaining three months)	$	207
2017	3,839
2018	4,442

The aggregate intrinsic value of options exercised under all option plans was $42,000 for the nine months ended September 30, 2016 determined as of the date of option exercise. No options were exercised during the nine months ended September 30, 2015.

The Company recognized stock-based compensation expense within the condensed consolidated statements of operations and comprehensive loss as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2016		2015		2016		2015
Research and development	$	139	$	192	$	516	$	456
General and administrative	864		766		2,652		2,404
Total	$	1,003	$	958	$	3,168	$	2,860

At September 30, 2016, there were 111,000 unvested options outstanding with performance conditions related to the achievement of certain clinical milestones. During the three and nine months ended September 30, 2016, stock-based compensation expense recorded for theses performance-based options was insignificant to the interim condensed consolidated financial statements.

In April 2016, the Company’s board of directors approved an amendment and restatement of the Company’s Fourth Amended and Restated 2011 Stock Option and Incentive Plan (the “2011 Plan”) to, among other things, increase the maximum number of shares that may be issued under the 2011 Plan from 3,602,328 to 5,002,328 shares. The amendment and restatement of the 2011 Plan was approved by the Company’s stockholders on June 14, 2016.

As of September 30, 2016, there was unrecognized stock-based compensation expense of $6.2 million related to stock options. The Company expects to recognize those costs over a weighted average period of 2.16 years.

Stock-based compensation expense for stock options is estimated at the grant date based on the fair value using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of all stock options granted was estimated using the following ranges of weighted-average assumptions:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2016	2015	2016	2015
Expected dividend yield	—	—	—	—
Risk-free interest rates	0.59% - 1.39%	1.59% - 1.64%	0.59% - 1.97%	1.52% - 2.08%
Expected term in years	0.95 - 4.43	5.52 - 6.08	0.95 - 8.14	5.49 - 8.06
Expected volatility	73% - 87%	78% - 80%	73% - 94%	78% - 92%

On January 6, 2016, the Company granted certain of its executive officers non-qualified stock options to purchase 206,625 shares of the Company’s common stock that vest on a monthly basis in equal installments over 48 months following the grant date if the Company's stock price equals or exceeds $6.00 for 20 consecutive trading days on or before June 30, 2017. The options expire ten years from the date of the grant.

The fair values of these options were determined using a Monte Carlo simulation model incorporating the following ranges of weighted-average assumptions:

	Nine Months Ended September 30, 2016
Expected dividend yield	—
Risk-free interest rates	1.82% - 2.05%
Expected term in years	6.02 - 8.00
Expected volatility	77% - 89%
Weighted-average fair value per share	1.33 - 1.42

The estimated expense for these awards is being recognized on an accelerated basis over the estimated requisite service period, with no adjustments in the future periods based upon the Company's actual common stock price. The Company recorded $0.1 million in stock-based compensation expense during the nine months ended September 30, 2016 in connection with such awards. Stock-based compensation expense related to these awards was insignificant during the three months ended September 30, 2016.

Discontinued Operations

Discontinued Operations

On September 11, 2013, the Company announced a restructuring plan related to the operations of Tranzyme Pharma Inc. (“Tranzyme Pharma”). On December 13, 2013, the Company entered into a Technology Transfer and License Agreement with Genentech, Inc. ("Genentech"), and F. Hoffman-La Roche, Ltd. ("Roche") to sell certain Canadian fixed assets and materials, the MATCH technology and rights to the Genentech and Roche customer agreements and related intellectual property through licensing of patents for $4.0 million. The Company concluded that the operations of Tranzyme Pharma and related asset groups sold to Genentech and Roche would be accounted for as discontinued operations as the operations and cash flows of the discontinued component or asset group would be eliminated from ongoing operations of the Company and there would not be significant involvement in the component or asset group after the disposal transaction.

In 2014, the Company completed its obligations under the Technology Transfer and License Agreement with Genentech and Roche and recognized a gain on disposal of assets of $1.1 million within discontinued operations. There was $0.2 million in income recorded in discontinued operations for the three and nine months ended September 30, 2015 that relates to certain foreign research credits received.

Earnings Per Share [Abstract]

Net Loss Per Share

Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. Potentially dilutive securities which include warrants and outstanding stock options have been excluded from the computation of diluted net loss per share as the effect of their inclusion would be anti-dilutive. For all periods presented, diluted and basic net loss per share were identical due to the Company’s net loss position.

The following table presents the computation of net loss per share (in thousands, except share and per share data):

Total	4,668,077	3,337,893	4,677,467	3,088,773

The Company has utilized the control number concept in the computation of diluted earnings per share to determine whether potential common stock instruments are dilutive. The control number used is loss from continuing operations. The control number concept requires that the same number of potentially dilutive securities applied in computing diluted earnings per share from continuing operations be applied to all other categories of income or loss, regardless of their anti-dilutive effect on such categories. Therefore, no dilutive effect has been recognized in the calculation of income from discontinued operations per share for the three and nine months ended September 30, 2015.

Summary of Significant Accounting Policies (Policies)

Sep. 30, 2016

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company and its wholly-owned subsidiary have been prepared in accordance with United States of America generally accepted accounting principles ("U.S. GAAP") for interim financial statements and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. This quarterly report should be read in conjunction with the consolidated financial statements and related notes included in the Company’s annual report on Form 10-K for the year ended December 31, 2015.

Consolidation

Unaudited Interim Financial Information

The accompanying condensed consolidated financial statements and related disclosures are unaudited, have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented. The consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Short-term investments

Investments in Marketable Securities

All investments in marketable securities have been classified as "available-for-sale" and are carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities. Unrealized gains and losses are excluded from earnings and are reported as a component of accumulated comprehensive income. Realized gains and losses and declines in fair value judged to be other than temporary, if any, on investments in marketable securities are included in interest and other income (expense), net. The cost of securities sold is based on the specific-identification method. Interest earned on investments in marketable securities is included in interest and other income

New Accounting Pronouncements

Recent Accounting Pronouncements

Occasionally, new accounting standards are issued or proposed by the Financial Accounting Standards Board (the "FASB"), or other standards setting bodies that the Company adopts by the effective date specified within the standard. Unless otherwise discussed, standards that do not require adoption until a future date are not expected to have a material impact on the Company's condensed consolidated financial statements upon adoption.

Recent Accounting Updates Not Yet Effective

In August 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-15, Classification of Certain Cash Receipts and Cash Payments, which aims to eliminate diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other Topics. ASU 2016-15 is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2017. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815), Contingent Put and Call Options in Debt Instruments. This ASU clarifies the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts. An entity performing the assessment under the amendments in this ASU is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. The new standard simplifies the embedded derivative analysis for debt instruments containing contingent call or put options by removing the requirement to assess whether a contingent event is related to interest rates or credit risks. This guidance should be applied on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year in which the amendments are effective, and is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718), Compensation - Stock Compensation. The new guidance simplifies several aspects of the accounting for share-based payments, including immediate recognition of all excess tax benefits and deficiencies in the income statement, changing the threshold to qualify for equity classification up to the employees' maximum statutory tax rates, allowing an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur, and clarifying the classification on the statement of cash flows for the excess tax benefit and employee taxes paid when an employer withholds shares for tax-withholding purposes. ASU 2016-09 is effective for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases, to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The standard will become effective for interim and annual periods beginning after December 15, 2018, with early adoption permitted. The guidance is required to be adopted at the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact of the adoption of this standard on its condensed consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. The standard’s core principle is that a reporting entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The standard will become effective for the Company beginning in the first quarter of 2018. Early adoption is permitted in 2017. Entities have the option of using either a full retrospective or a modified retrospective approach to adopt this new guidance. In March and April 2016, the FASB issued ASU 2016-08 Revenue From Contracts With Customers: Principal vs. Agent Considerations and ASU 2016-10 Revenue From Contracts with Customers: Identifying Performance Obligations and Licensing to provide supplemental adoption guidance and clarification to ASU 2014-09. The Company is currently evaluating the impact that the adoption of this standard will have on its condensed consolidated financial statements.

Earnings Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common shares and common share equivalents outstanding for the period. Common stock equivalents are only included when their effect is dilutive. Potentially dilutive securities which include warrants and outstanding stock options have been excluded from the computation of diluted net loss per share as the effect of their inclusion would be anti-dilutive.
