Neothetics, Inc.

Notes to Unaudited Condensed Financial Statements

1. Organization and Basis of Presentation

Neothetics, Inc. (Neothetics or the Company) was incorporated in Delaware on February 1, 2007, under the name Lipothera, Inc.  In September 2008, the Company changed its name to Lithera, Inc.  In August 2014, the Company changed its name to Neothetics, Inc.  The Company is a clinical-stage specialty pharmaceutical company developing therapeutics for the aesthetic market. The Company’s lead product candidate is a novel injectable treatment for localized fat reduction and body contouring and the current focus is on the submental region for double chin.

As of March 31, 2017, the Company has devoted substantially all of its efforts to product development, raising capital, and building infrastructure and has not realized revenues from its planned principal operations.

The accompanying unaudited financial statements of the Company should be read in conjunction with the audited financial statements and notes thereto as of and for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K (Annual Report) filed with the Securities and Exchange Commission (SEC). The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, since they are interim statements, the accompanying financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

The Company has incurred significant net losses from its operations since its inception and has an accumulated deficit of $129.0 million as of March 31, 2017.  In the first quarter of 2017, the Company used $1.8 million of cash in operations.  At March 31, 2017, the Company had cash and cash equivalents of $9.7 million.  Management expects operating losses and negative cash flows to continue for at least the next year as the Company continues to incur costs related to ongoing Phase 2 proof of concept trial and any future clinical trials to further the development of LIPO-202.  Based on the Company’s operating plans, management believes the Company’s cash and cash equivalents will not be sufficient to fund its operations beyond April 2018.  As a result, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements for the quarter ended March 31, 2017 are issued.

Management’s ability to continue as a going concern is dependent upon its ability to raise additional funding.  Management intends to raise additional capital through public or private equity offerings or collaboration, licensing, or other similar arrangement. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity to raise additional funds, its existing stockholders may experience dilution, and the new equity may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of our research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occur, the Company’s ability to achieve the development and commercialization goals would be adversely affected.

The financial statements have been prepared on a going concern basis and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.  Actual results could differ from those estimates.

5

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of 90 days or less at the date of purchase to be cash equivalents.  Cash and cash equivalents include cash in readily available checking and money market accounts.

Restricted Cash

 Restricted cash as of March 31, 2017 represents a $93,382 restricted money market account used to secure the standby letter of credit issued in connection with a lease amendment.  The restriction will lapse when the standby letter of credit expires (see Note 5 “Debt”).  

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the balance sheets that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31,
	2017		2016
Cash and cash equivalents	$	9,749,756	$	24,089,869
Restricted cash		93,382		200,000
Total cash, cash equivalents and restricted cash	$	9,843,138	$	24,289,869

Concentrations of Credit Risk

          Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash due to the financial position of the depository institution in which those deposits are held.

Fair Value of Financial Instruments

The carrying amounts of prepaid and other current assets, accounts payable and accrued expenses are reasonable estimates of their fair value because of the short maturity of these items.

Property and Equipment

Property and equipment, which primarily consist of office furniture and equipment and computer equipment, are stated at cost and depreciated over the estimated useful lives of the assets (three to five years) using the straight-line method.

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment. An impairment loss is recorded if and when events and circumstances indicate that assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. While the Company's current and historical operating losses and negative cash flows are indicators of impairment, management believes that future cash flows to be received support the carrying value of its long-lived assets and, accordingly, has not recognized any impairment losses since inception.

Research and Development Costs

Research and development expenses consist primarily of salaries and related overhead expenses, fees paid to consultants and contract research organizations, costs related to acquiring and manufacturing clinical trial materials, and costs related to compliance with regulatory requirements.

All research and development costs are charged to expense as incurred.

Income Taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are recorded when the realizability of such deferred tax assets is not more likely than not.

6

The guidance on accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. The Company has not recognized interest and penalties in the balance sheets or statements of operations. The Company is subject to taxation in the U.S. and state jurisdictions. The Company’s tax years from inception are subject to examination by the United States and California authorities due to the carryforwards of unutilized net operating losses (NOLs) and research and development credits.

Share-Based Compensation

Share-based compensation expense for stock option grants, restricted stock awards and employee stock purchase plan shares is recorded at the estimated fair value of the award as of the grant date and is recognized as expense on a straight-line basis over the requisite service period of the stock-based award. The estimation of stock options, restricted stock awards and employee stock purchase plan fair value requires management to make estimates and judgments about, among other things, employee exercise behavior, forfeiture rates and volatility of the Company’s common stock. The judgments directly affect the amount of compensation expense that will be recognized.

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, without consideration for common stock equivalents. 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 during the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities, which include warrants and outstanding stock options and restricted stock awards under the stock compensation plans, have been excluded from the computation of diluted net loss per share as they would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to compute basic and diluted shares outstanding due to the Company’s net loss position.

The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because to do so would be anti-dilutive.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. This pronouncement gives guidance to clarify how certain cash receipts and payments should be presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the timing of adoption of this guidance and the impact of the adoption of this guidance on its financial statements.

7

In November 2016, the Financial Accounting Standards Board (the “FASB) issued Accounting Standards Update (or “ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Adoption of this guidance did not have an impact on our financial position or results of operations.

3. Fair Value Measurements

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, accounts payable, accrued expenses, including warrants issued in connection with financing arrangements, and long-term debt. Fair value estimates of these instruments are made at a specific point in time based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash and cash equivalents, accounts payable, and accrued expenses are generally considered to be representative of their respective fair values because of the short-term nature of these instruments.   The Company believes that the fair value of long-term debt approximates its carrying value based on the borrowing rates currently available to the Company for loans with similar terms.

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers or sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance prioritizes three levels of inputs into the following hierarchy:

Level 1 — 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.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016 are as follows:

			Fair Value Measurements at Reporting Date Using
	Balance as of March 31, 2017		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

5. Debt

Loans

In February 2010, and as amended during 2012, the Company entered into a loan and security agreement (2010 Loan and Security Agreement) with Silicon Valley Bank (SVB), for borrowings of $3,750,000, collateralized by all assets of the Company. In connection with the borrowings, the Company issued warrants to the bank for the purchase of a total of 64,865 shares of Series B convertible preferred stock and warrants to purchase 75,000 shares of Series C convertible preferred stock. Effective upon the IPO, this was converted to a warrant to purchase 24,419 shares of common stock at a weighted average exercise price of $9.90 and expire ten years from the date of issuance. The 2010 Loan and Security Agreement was fully paid off in June 2014.

In June 2014, the Company entered into a Loan and Security Agreement (Loan Agreement) with Hercules Technology Growth Capital Inc. that provided for borrowings up to $10.0 million available to the Company in two tranches. Upon closing of the Loan Agreement, the Company borrowed $4.0 million. In October 2014, the Company entered into the first amendment of the Loan Agreement and borrowed the remaining $6.0 million available under the agreement.

In connection with the Loan Agreement, in June 2014, the Company issued warrants to purchase shares of Series C convertible preferred stock equal to 4% of the amount advanced under the loan. Effective upon the IPO, this was converted to a warrant to purchase 46,838 shares of common stock at $8.54, which expires eight years after the date of issuance. The fair value of the warrants issued was $207,429, based on the fair value of such Series C warrants at the date of issuance. The warrants’ fair value and financing fees of approximately $133,000 were recorded as a debt discount.

In March 2016, the Company entered into the second amendment of the Loan Agreement that provided for a prepayment of the outstanding loan carrying amount of $5.5 million with a prepayment fee of $110,000. In connection with the second amendment, the Company re-priced the outstanding warrants to purchase 46,838 shares of common stock at a new exercise price of $0.62, which expire in September 2022 unless exercised prior to such expiration date. The Company recorded a debt discount of $9,417 associated with the fair value of the warrants issued in connection with the amendment. In addition, the Company incurred loan amendment fees and legal fees of $52,400, which the Company recorded as a debt discount.

In September 2016, the Company prepaid the remaining outstanding balance under the Loan Agreement at a carrying amount of $4.0 million with a prepayment fee of $120,000 and an end of term fee of $300,000.  Accordingly, the Loan Agreement was terminated on September 23, 2016.  Upon termination of the Loan Agreement, the prepayment fees of $230,000 and unamortized end of term fee of $260,000 were recorded as interest expense.

From June 2014 through payoff in September 2016, the Company paid interest equal to the greater of either 9.0%, plus the Prime Rate as reported in The Wall Street Journal, less 3.25% or 9.0%. The Company recorded total interest expense of $0 and $265,124 related to the Loan Agreement for the three months end March 31, 2017 and 2016, respectively.

Letter of Credit

In January 2015, the Company executed a lease amendment with LJ Gateway, LLC for new office space. In connection with this lease amendment the Company issued a stand-by letter of credit in the amount of $200,000 in lieu of a security deposit. Pursuant to the terms set forth in the lease amendment, as of March 31, 2017, the stand-by letter of credit was reduced to $93,382.  The standby letter of credit is secured by a restricted money market account. The terms of the standby letter of credit expire in May 2020 and are subject to automatic yearly renewal prior to this date.

Common Stock

On December 1, 2015, the Company entered into a Controlled Equity Offering Sales Agreement, or Sales Agreement, with Cantor Fitzgerald, as a sales agent pursuant to which the Company may offer and sell from time to time, through Cantor Fitzgerald shares of Neothetics common stock, par value $0.0001 per share, having an aggregate offering price of up to $20.0 million.

This Lease Amendment provides for additional space consisting of approximately 3,580 square feet located at Suite No. 250, 9171 Towne Centre Drive, San Diego California, which the Company occupies as its headquarters.

Upon occurrence of Abacus retaining possession of the original premises in February 2017, Abacus received rent abatement for months one, three, and four as well as a discount of 50% off the base rent for months five through nine. Abacus paid the Company a base rent of $27,768 for the second month’s rent and $30,317 security deposit. The base rent will increase by three percent on each annual anniversary. The Company has recorded the rental income collected or accrued under the sublease as a reduction of rent expense.  Rent expense and sublease rental income for the three months ended March 31, 2017 were $94,762 and $39,193, respectively.

The following table summarizes the minimum lease payments and sublease receipts under the lease agreements:

Overview

We are a clinical-stage specialty pharmaceutical company developing therapeutics for the aesthetic market. Our initial focus is on localized fat reduction and body contouring. Our lead product candidate, LIPO-202, is a first-in-class injectable formulation of the long-acting ß2-adrenergic receptor agonist, salmeterol xinafoate, which is an active ingredient in the U.S. Food and Drug Administration, or FDA, approved inhaled products SEREVENT DISKUS®, ADVAIR HFA® and ADVAIR DISKUS®. We previously completed development of LIPO-202 in our Phase 2 RESET trial in 2013, showing a statistically significant reduction in central abdominal bulging due to subcutaneous fat in non-obese patients.  In 2015, we conducted two pivotal U.S. Phase 3 trials of LIPO-202, which  failed to meet their co-primary composite or secondary endpoints as well as showing near identical results with no bias in sites or subgroups. In these trials, AbCONTOUR1 and AbCONTOUR2, LIPO-202 continued to show a safety profile similar to placebo. We, and expert consultants that we engaged, conducted a detailed review of these unexpected trial results. Based on the results of the review by us and our expert consultants, we concluded that modifications intended to make LIPO-202 commercially ready may have affected the drug product.

In February 2016, our Board of Directors established an Operating Committee to assist with many of the responsibilities arising in the day-to-day operations of the company that normally would be managed by our Chief Executive Officer and President, which position is currently vacant.  The Operating Committee currently is comprised of three members of the Board of Directors; Martha J. Demski, Kim Kamdar, Ph.D, and Jeffrey Nugent.  In June 2016, we formed a Development Committee led by medical aesthetic and dermatology veteran, Dan Piacquadio, M.D., and includes additional members of Neothetics management and other outside consultants.  The Development Committee is responsible for general oversight and overall strategy for the LIPO-202 development plan activities including Chemistry, Manufacturing and Controls, or CMC, clinical and regulatory.   As part of our continuing development efforts, we completed manufacturing of the modified formulation of LIPO-202 for use in our planned Phase 2 proof of concept trial, which is primarily based on the drug product formulation used in the Phase 2 RESET trial.  

We have completed manufacturing of a modified formulation of LIPO-202, which is primarily based on the drug product formulation used in the Phase 2 RESET trial. We are continuing our LIPO-202 development program focused on localized fat reduction and body contouring using this modified formulation of LIPO-202. In November 2016, we announced plans to prioritize our efforts and resources on the Phase 2 proof of concept trial for the reduction of localized fat deposits under the chin, or submental fat.  We initiated this trial with the modified formulation of LIPO-202 in December 2016 and expect top-line results in late June of 2017.  We also plan to continue development of LIPO-202 for the reduction of central abdominal bulging, pending results from the submental Phase 2 proof of concept trial and available capital resources. Since commencing operations in February 2007, we have invested substantially all of our efforts and financial resources in the research and development and commercial planning for LIPO-202, which is currently our lead product candidate.  Through March 31, 2017, we have funded substantially all of our operations through the sale and issuance of our preferred stock, venture debt, convertible debt and the sale of shares in our initial public offering.

We have never been profitable and, as of March 31, 2017, we had an accumulated deficit of $129.0 million. We incurred net losses of $3.0 million and $6.0 million for the three months ended March 31, 2017 and 2016, respectively.  We expect to continue to incur net operating losses for at least the next several years as we advance LIPO-202 through clinical development, seek regulatory approval, prepare for and, if approved, proceed to commercialization.  We have no manufacturing facilities and all of our manufacturing activities are contracted out to third parties.  Additionally, we currently utilize third-party CROs to carry out our clinical development.  We will need substantial additional funding to support our operating activities including further development of LIPO-202. Adequate funding may not be available to us on acceptable terms, or at all.  Our failure to obtain sufficient funds on acceptable terms when needed could have a material adverse effect on our business, results of operations, and financial condition.

JOBS Act

In April 2012, the Jumpstart Our Business Startups Act of 2012, or JOBS Act, was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for an “emerging growth company.” As an “emerging growth company,” we are electing not to take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards, and as a result, we will comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. Section 107 of the JOBS Act provides that our decision not to take advantage of the extended transition period is irrevocable. In addition, we are in the process of evaluating the benefits of relying on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if as an “emerging growth company” we choose to rely on such exemptions, we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, as amended, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our IPO or until we no longer meet the requirements of being an “emerging growth company,” whichever is earlier.

Basis of Presentation

Revenues

Our ability to generate revenues from product sales, which we do not expect will occur before 2020, at the earliest, will depend heavily on our obtaining marketing approval from the FDA for, and, subsequent to that, our successful commercialization of, LIPO-202. If we fail to complete the development of LIPO-202 in a timely manner or to obtain regulatory approval, our ability to generate future revenue, and our results of operations and financial position, would be materially adversely affected.

Research and Development Expenses

Our research and development expenses consist primarily of:

• fees paid to clinical consultants, clinical trial sites and vendors, including CROs in conjunction with implementing and monitoring our preclinical and clinical trials and acquiring and evaluating preclinical and clinical trial data, including all related fees, such as for investigator grants, patient screening fees, laboratory work and statistical compilation and analysis;

• expenses related to preclinical studies, clinical trials and related clinical manufacturing, materials and supplies;

• expenses related to compliance with drug development regulatory requirements in the United States and other foreign jurisdictions; and

• personnel costs, including cash compensation, benefits and share-based compensation expense.

We expense both internal and external research and development costs in the periods in which they are incurred. To date, substantially all our research and development expenses have related to the development of LIPO-202.  For the three months ended March 31, 2017 and 2016, we incurred costs of $1.5 million and $3.3 million, respectively,  on research and development expenses.

We do not allocate compensation expense to individual product candidates, as we are organized and record expense by functional department and our employees may allocate time to more than one development project. We do not utilize a formal time allocation system to capture expenses on a project-by-project basis.

Conducting significant research and development is central to our business and strategy. Product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and greater duration of late stage clinical trials as compared to earlier clinical and preclinical development.  Our research and development expenses decreased temporarily and we expect that these expenses will increase with the initiation of our Phase 2 proof of concept trial in December 2016.  The costs of clinical trials may vary significantly over the life of a project owing to a number of factors.

14

General and Administrative Expenses

Our general and administrative expenses primarily consist of personnel costs, including cash compensation, benefits and share-based compensation expense, associated with our executive, accounting and finance departments. Other general and administrative expenses include costs in connection with patent filing, prosecution and defense, facility, information technology costs and professional fees for legal, consulting, marketing, audit and tax services.

Interest Income    

Our interest income consists primarily of interest received or earned on our cash and cash equivalents. We expect interest income to vary each reporting period depending on our average cash and cash equivalents and marketable securities balances during the period and applicable interest rates. To date, our interest income has not been significant in any individual period.

Interest Expense

Our interest expense consists of cash and noncash interest costs related to our borrowings. The noncash interest costs consist of the amortization of the fair value of warrants that were issued in connection with our borrowings, with the initial fair value of the warrants being amortized to interest expense over the term of the governing agreements, and the amortization of other debt issuance costs, primarily legal and banker fees, over the period the related convertible notes were outstanding. As we prepaid in full the Hercules debt facility in September 2016, there was no interest expense for the three months ended March 31, 2017.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, including those related to stock-based compensation and warrant liabilities. These estimates are based on historical experience and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for judgments about the carrying values of assets and liabilities and the recognition of revenues and expenses. Actual results may differ from these estimates under different assumptions or conditions. There have been no material changes to our critical accounting policies and estimates from the information provided in Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies Involving Management Estimates and Assumptions,” included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Net loss	$	(3,014	)	$	(6,026	)	$	3,012

Research and Development Expenses. Research and development expenses decreased by $1.7 million, to $1.6 million for the three months ended March 31, 2017 from $3.3 million for the three months ended March 31, 2016. Approximately $1.9 million of the decrease was due to the completion of the majority of the close out activities for our AbCONTOUR1 and AbCONTOUR2 U.S. Phase 3 clinical trials and the supplemental clinical trials.  Approximately $0.9 million of the decrease was due to the reduction of personnel and other research and development activities.  The decreases were offset by $1.1 million increase in costs related to the Phase 2 proof of concept trial for the reduction of localized fat deposits under the chin, or submental fat.  

General and Administrative Expenses. General and administrative expenses decreased by $1.0 million to $1.5 million for the three months ended March 31, 2017, from $2.5 million for the three months ended March 31, 2016.  A decrease of $1.1 million was

15

due to the reduction of personnel and $0.1 million in legal expenses. The decreases were offset by $0.3 million loss from the facility sublease.      

Interest Income. Interest income decreased by $8,000, to $12,000 for the three months ended March 31, 2017 from $20,000 for the three months ended March 31, 2016. The decrease resulted from a lower cash balance during the three months ended March 31, 2017.

Interest Expense. Interest expense decreased by $265,000, to zero for the three months ended March 31, 2017 from $265,000 for the three months ended March 31, 2016. The decrease was due to the early prepayment of long-term debt in September 2016.  

Liquidity and Capital Resources

We have incurred losses and negative cash flows from operating activities for the three months ended March 31, 2017 and 2016. As of March 31, 2017, we had an accumulated deficit of $129.0 million. We anticipate that we will continue to incur net losses for the foreseeable future as we continue the development and potential commercialization of LIPO-202 and incur additional costs associated with being a public company.  Based on our operating plans, we do not expect that our existing capital resources will be sufficient to fund our operations beyond the first half of 2018.  These factors raise substantial doubt about our ability to continue as a going concern.  

Prior to our IPO in November 2014, we funded our operations primarily through private placements of our convertible preferred stock, warrants, venture debt and convertible debt.  In November 2014, we completed our IPO of 4,650,000 shares of common stock at an offering price of $14.00 per share.  We received net proceeds of approximately $57.7 million, after deducting underwriting discounts, commissions and offering-related transaction costs. At March 31, 2017, we had cash and cash equivalents of approximately $9.7 million.

On December 1, 2015, the Company entered into a Controlled Equity Offering Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as a sales agent (“Cantor Fitzgerald”) pursuant to which the Company may offer and sell from time to time, through Cantor Fitzgerald shares of Neothetics common stock, par value $0.0001 per share, having an aggregate offering price of up to $20.0 million. As of March 31, 2017, no shares were issued pursuant to the Sales Agreement.

To fund further operations, we intend to raise additional capital. If we are unable to obtain additional financing on commercially reasonable terms, or at all, our business, financial condition and results of operations will be materially adversely affected and we may be unable to continue as a going concern. If we are unable to continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our financial statements. We may obtain additional financing in the future through the issuance of our common stock from other equity or debt financings or through collaborations or partnerships with other companies.  The financial statements have been prepared on a going concern basis and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of this uncertainty.

Summary Statement of Cash Flows

The following table sets forth a summary of the net cash flow activity for each of the periods set forth below (in thousands):

	March 31,
	2017			2016
Net cash used in operating activities	$	(1,844	)	$	(7,606	)
Net cash provided by investing activities		6		—
Net cash provided by (used in) financing activities		3			(6,052	)
Net decrease in cash, cash equivalents and restricted cash	$	(1,835	)	$	(13,658	)

16

Cash Flows from Operating Activities. Net cash used in operating activities was $1.8 million and $7.6 million for the three months ended March 31, 2017 and 2016, respectively. The decrease in cash used in operations for three months ended March 31, 2017 compared to March 31, 2016 was primarily due to the decrease in net loss of $3.0 million and in changes in accounts payable and accrued expenses of $4.0 million. The decreases were offset by share-based compensation of $0.6 million and the change in prepaid expenses of $0.7 million.  

Cash Flows from Investing Activities. Net cash provided by investing activities was $6,000 and $0 for the three months ended March 31, 2017 and 2016, respectively. During the three months ended March 31, 2017, cash provided by investing activities consisted of proceeds from sale of property and equipment.  

Cash Flows from Financing Activities. Net cash provided by financing activities was approximately $3,000 for the three months ended March 31, 2017 and net cash used in financing activities was $6.0 million for three months ended March 31, 2016. During the three months ended March 31, 2017, cash provided by financing activities included proceeds from issuance of common stock from exercise of options.  During the three months ended March 31, 2016, cash used in financing activities consisted primarily of principal payments of $0.5 million and prepayment of long-term debt of $5.5 million.

Operating and Capital Expenditure Requirements

Our future capital requirements are difficult to forecast and will depend on many factors, including:

• the initiation, progress, costs and results of our planned Phase 2 clinical trials of LIPO 202;

• the outcome, timing and cost of regulatory approvals;

• the costs and timing of establishing sales, marketing and distribution capabilities, if LIPO-202 is approved;

• delays that may be caused by changing regulatory requirements;

• the costs involved in filing and prosecuting patent applications and enforcing and defending patent claims; and

• the extent to which we acquire or invest in businesses, products or technologies.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity offerings, debt financings, collaborations, strategic partnerships and licensing arrangements. We do not have any committed external source of funds. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our common stockholders. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through collaborations, strategic partnerships or licensing arrangements with third parties, we may have to relinquish valuable rights to our product candidates, our other technologies, future revenue streams or research programs or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market LIPO-202 even if we would otherwise prefer to develop and market LIPO-202 ourselves.

Contractual obligations and commitments

In January 2015, the Company entered into a noncancelable operating lease (see Note 7 “Commitments”). Other than described in Note 5 and Note 7 there have been no material changes outside the ordinary course of our business to the contractual obligations we reported in “Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations – Contractual obligations and commitments” in our annual report on Form 10-K for the year ended December 31, 2016.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements (as defined by applicable regulations of the Securities and Exchange Commission) that are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

17

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

As of March 31, 2017, there have been no material changes in our market risk from that described in “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our annual report on Form 10-K for the year ended December 31, 2016.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this quarterly report on Form 10-Q. Based on such evaluation, our principal executive officer and principal financial officer has concluded that as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during our latest fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

18

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

We are currently not a party to any material legal proceedings.

Item 1A. Risk Factors.

The risk factors set forth below contain material changes to the risk factors previously disclosed and included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.  An investment in our common stock involves a high degree of risk. You should consider carefully the risks and uncertainties described under Item 1A of Part I of our Annual Report on Form 10-K, as updated in this Item 1A (collectively, Risk Factors) together with all other information contained or incorporated by reference in this report before you decide to invest in our common stock. If any of the Risk Factors were to actually occur, our business, financial condition, results of operations and our future growth prospects could be materially and adversely affected. Under the circumstances, the trading price of our common stock could decline, and you may lose all or part of your investment.

Based on our operating plans, management believes the our current cash and cash equivalents will not be sufficient to fund our operations beyond April 2018, and as a result, there is substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements for the quarter ended March 31, 2017 are issued. 

            Our recurring losses from operations, liquidity position, and debt service requirements raises substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements for the quarter ended March 31, 2017 are issued.  Our ability to continue as a going concern could materially limit our ability to raise additional funds through the issuance of new debt or equity securities or otherwise. Future audit reports from our independent registered public accounting firm on our financial statements may also include an explanatory paragraph with respect to our ability to continue as a going concern.  To date, our operating losses have been funded primarily from outside sources of invested capital and gross profits.  We have had, and we will likely continue to have, an ongoing need to raise additional cash from outside sources to fund our future operations. However, no assurance can be given that additional capital will be available when required or on terms acceptable to us. If we are unsuccessful in our efforts to raise any such additional capital, we would be required to take actions that could materially and adversely affect our business, including significant reductions in our research, development and administrative operations (including reduction of our employee base), possible surrender or other disposition of our rights to some technologies or product opportunities, delaying of our clinical trials or curtailing or ceasing operations.   We also cannot give assurance that we will achieve sufficient revenues in the future to achieve profitability and cash flow positive operations to allow us to continue as a going concern.  The perception that we may not be able to continue as a going concern may cause third parties to choose not to deal with us due to concerns about our ability to meet our contractual obligations, which could have a material adverse effect on our business.

Organization Consolidation And Presentation Of Financial Statements [Abstract]

Organization and Basis of Presentation

1. Organization and Basis of Presentation

Neothetics, Inc. (Neothetics or the Company) was incorporated in Delaware on February 1, 2007, under the name Lipothera, Inc.  In September 2008, the Company changed its name to Lithera, Inc.  In August 2014, the Company changed its name to Neothetics, Inc.  The Company is a clinical-stage specialty pharmaceutical company developing therapeutics for the aesthetic market. The Company’s lead product candidate is a novel injectable treatment for localized fat reduction and body contouring and the current focus is on the submental region for double chin.

As of March 31, 2017, the Company has devoted substantially all of its efforts to product development, raising capital, and building infrastructure and has not realized revenues from its planned principal operations.

The accompanying unaudited financial statements of the Company should be read in conjunction with the audited financial statements and notes thereto as of and for the year ended December 31, 2016 included in the Company’s Annual Report on Form 10-K (Annual Report) filed with the Securities and Exchange Commission (SEC). The accompanying financial statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, since they are interim statements, the accompanying financial statements do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying financial statements reflect all adjustments (consisting of normal recurring adjustments) that are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods presented. Interim results are not necessarily indicative of results for a full year.

The Company has incurred significant net losses from its operations since its inception and has an accumulated deficit of $129.0 million as of March 31, 2017.  In the first quarter of 2017, the Company used $1.8 million of cash in operations.  At March 31, 2017, the Company had cash and cash equivalents of $9.7 million.  Management expects operating losses and negative cash flows to continue for at least the next year as the Company continues to incur costs related to ongoing Phase 2 proof of concept trial and any future clinical trials to further the development of LIPO-202.  Based on the Company’s operating plans, management believes the Company’s cash and cash equivalents will not be sufficient to fund its operations beyond April 2018.  As a result, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements for the quarter ended March 31, 2017 are issued.

Management’s ability to continue as a going concern is dependent upon its ability to raise additional funding.  Management intends to raise additional capital through public or private equity offerings or collaboration, licensing, or other similar arrangement. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity to raise additional funds, its existing stockholders may experience dilution, and the new equity may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of our research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occur, the Company’s ability to achieve the development and commercialization goals would be adversely affected.

The financial statements have been prepared on a going concern basis and do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or amounts and classification of liabilities that may result from the outcome of this uncertainty.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of 90 days or less at the date of purchase to be cash equivalents.  Cash and cash equivalents include cash in readily available checking and money market accounts.

Restricted Cash

 Restricted cash as of March 31, 2017 represents a $93,382 restricted money market account used to secure the standby letter of credit issued in connection with a lease amendment.  The restriction will lapse when the standby letter of credit expires (see Note 5 “Debt”).  

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the balance sheets that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31,
	2017		2016
Cash and cash equivalents	$	9,749,756	$	24,089,869
Restricted cash		93,382		200,000
Total cash, cash equivalents and restricted cash	$	9,843,138	$	24,289,869

Concentrations of Credit Risk

          Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash due to the financial position of the depository institution in which those deposits are held.

Fair Value of Financial Instruments

The carrying amounts of prepaid and other current assets, accounts payable and accrued expenses are reasonable estimates of their fair value because of the short maturity of these items.

Property and Equipment

Property and equipment, which primarily consist of office furniture and equipment and computer equipment, are stated at cost and depreciated over the estimated useful lives of the assets (three to five years) using the straight-line method.

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment. An impairment loss is recorded if and when events and circumstances indicate that assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. While the Company's current and historical operating losses and negative cash flows are indicators of impairment, management believes that future cash flows to be received support the carrying value of its long-lived assets and, accordingly, has not recognized any impairment losses since inception.

Research and Development Costs

Research and development expenses consist primarily of salaries and related overhead expenses, fees paid to consultants and contract research organizations, costs related to acquiring and manufacturing clinical trial materials, and costs related to compliance with regulatory requirements.

All research and development costs are charged to expense as incurred.

Income Taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are recorded when the realizability of such deferred tax assets is not more likely than not.

The guidance on accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. The Company has not recognized interest and penalties in the balance sheets or statements of operations. The Company is subject to taxation in the U.S. and state jurisdictions. The Company’s tax years from inception are subject to examination by the United States and California authorities due to the carryforwards of unutilized net operating losses (NOLs) and research and development credits.

Share-Based Compensation

Share-based compensation expense for stock option grants, restricted stock awards and employee stock purchase plan shares is recorded at the estimated fair value of the award as of the grant date and is recognized as expense on a straight-line basis over the requisite service period of the stock-based award. The estimation of stock options, restricted stock awards and employee stock purchase plan fair value requires management to make estimates and judgments about, among other things, employee exercise behavior, forfeiture rates and volatility of the Company’s common stock. The judgments directly affect the amount of compensation expense that will be recognized.

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, without consideration for common stock equivalents. 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 during the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities, which include warrants and outstanding stock options and restricted stock awards under the stock compensation plans, have been excluded from the computation of diluted net loss per share as they would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to compute basic and diluted shares outstanding due to the Company’s net loss position.

The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because to do so would be anti-dilutive.

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. This pronouncement gives guidance to clarify how certain cash receipts and payments should be presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the timing of adoption of this guidance and the impact of the adoption of this guidance on its financial statements.

In November 2016, the Financial Accounting Standards Board (the “FASB) issued Accounting Standards Update (or “ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Adoption of this guidance did not have an impact on our financial position or results of operations.

Fair Value Disclosures [Abstract]

Fair Value Measurements

3. Fair Value Measurements

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, accounts payable, accrued expenses, including warrants issued in connection with financing arrangements, and long-term debt. Fair value estimates of these instruments are made at a specific point in time based on relevant market information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash and cash equivalents, accounts payable, and accrued expenses are generally considered to be representative of their respective fair values because of the short-term nature of these instruments.   The Company believes that the fair value of long-term debt approximates its carrying value based on the borrowing rates currently available to the Company for loans with similar terms.

The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers or sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance prioritizes three levels of inputs into the following hierarchy:

Level 1 — 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.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Assets and liabilities measured at fair value on a recurring basis as of March 31, 2017 and December 31, 2016 are as follows:

			Fair Value Measurements at Reporting Date Using

Loans

In February 2010, and as amended during 2012, the Company entered into a loan and security agreement (2010 Loan and Security Agreement) with Silicon Valley Bank (SVB), for borrowings of $3,750,000, collateralized by all assets of the Company. In connection with the borrowings, the Company issued warrants to the bank for the purchase of a total of 64,865 shares of Series B convertible preferred stock and warrants to purchase 75,000 shares of Series C convertible preferred stock. Effective upon the IPO, this was converted to a warrant to purchase 24,419 shares of common stock at a weighted average exercise price of $9.90 and expire ten years from the date of issuance. The 2010 Loan and Security Agreement was fully paid off in June 2014.

In June 2014, the Company entered into a Loan and Security Agreement (Loan Agreement) with Hercules Technology Growth Capital Inc. that provided for borrowings up to $10.0 million available to the Company in two tranches. Upon closing of the Loan Agreement, the Company borrowed $4.0 million. In October 2014, the Company entered into the first amendment of the Loan Agreement and borrowed the remaining $6.0 million available under the agreement.

In connection with the Loan Agreement, in June 2014, the Company issued warrants to purchase shares of Series C convertible preferred stock equal to 4% of the amount advanced under the loan. Effective upon the IPO, this was converted to a warrant to purchase 46,838 shares of common stock at $8.54, which expires eight years after the date of issuance. The fair value of the warrants issued was $207,429, based on the fair value of such Series C warrants at the date of issuance. The warrants’ fair value and financing fees of approximately $133,000 were recorded as a debt discount.

In March 2016, the Company entered into the second amendment of the Loan Agreement that provided for a prepayment of the outstanding loan carrying amount of $5.5 million with a prepayment fee of $110,000. In connection with the second amendment, the Company re-priced the outstanding warrants to purchase 46,838 shares of common stock at a new exercise price of $0.62, which expire in September 2022 unless exercised prior to such expiration date. The Company recorded a debt discount of $9,417 associated with the fair value of the warrants issued in connection with the amendment. In addition, the Company incurred loan amendment fees and legal fees of $52,400, which the Company recorded as a debt discount.

In September 2016, the Company prepaid the remaining outstanding balance under the Loan Agreement at a carrying amount of $4.0 million with a prepayment fee of $120,000 and an end of term fee of $300,000.  Accordingly, the Loan Agreement was terminated on September 23, 2016.  Upon termination of the Loan Agreement, the prepayment fees of $230,000 and unamortized end of term fee of $260,000 were recorded as interest expense.

From June 2014 through payoff in September 2016, the Company paid interest equal to the greater of either 9.0%, plus the Prime Rate as reported in The Wall Street Journal, less 3.25% or 9.0%. The Company recorded total interest expense of $0 and $265,124 related to the Loan Agreement for the three months end March 31, 2017 and 2016, respectively.

Letter of Credit

In January 2015, the Company executed a lease amendment with LJ Gateway, LLC for new office space. In connection with this lease amendment the Company issued a stand-by letter of credit in the amount of $200,000 in lieu of a security deposit. Pursuant to the terms set forth in the lease amendment, as of March 31, 2017, the stand-by letter of credit was reduced to $93,382.  The standby letter of credit is secured by a restricted money market account. The terms of the standby letter of credit expire in May 2020 and are subject to automatic yearly renewal prior to this date.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2017

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.  Actual results could differ from those estimates.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of 90 days or less at the date of purchase to be cash equivalents.  Cash and cash equivalents include cash in readily available checking and money market accounts.

Restricted Cash

Restricted Cash

 Restricted cash as of March 31, 2017 represents a $93,382 restricted money market account used to secure the standby letter of credit issued in connection with a lease amendment.  The restriction will lapse when the standby letter of credit expires (see Note 5 “Debt”).  

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the balance sheets that sum to the total of the same such amounts shown in the statement of cash flows.

	March 31,
	2017		2016
Cash and cash equivalents	$	9,749,756	$	24,089,869
Restricted cash		93,382		200,000
Total cash, cash equivalents and restricted cash	$	9,843,138	$	24,289,869

Concentrations of Credit Risk

Concentrations of Credit Risk

          Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits. The Company has not experienced any losses in such accounts and believes it is not exposed to significant risk on its cash due to the financial position of the depository institution in which those deposits are held.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of prepaid and other current assets, accounts payable and accrued expenses are reasonable estimates of their fair value because of the short maturity of these items.

Property and Equipment

Property and Equipment

Property and equipment, which primarily consist of office furniture and equipment and computer equipment, are stated at cost and depreciated over the estimated useful lives of the assets (three to five years) using the straight-line method.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

Long-lived assets consist primarily of property and equipment. An impairment loss is recorded if and when events and circumstances indicate that assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. While the Company's current and historical operating losses and negative cash flows are indicators of impairment, management believes that future cash flows to be received support the carrying value of its long-lived assets and, accordingly, has not recognized any impairment losses since inception.

Research and Development Costs

Research and Development Costs

Research and development expenses consist primarily of salaries and related overhead expenses, fees paid to consultants and contract research organizations, costs related to acquiring and manufacturing clinical trial materials, and costs related to compliance with regulatory requirements.

All research and development costs are charged to expense as incurred.

Income Taxes

Income Taxes

The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and the tax reporting basis of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse. Valuation allowances are recorded when the realizability of such deferred tax assets is not more likely than not.

The guidance on accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s policy is to recognize interest expense and penalties related to income tax matters as a component of income tax expense. The Company has not recognized interest and penalties in the balance sheets or statements of operations. The Company is subject to taxation in the U.S. and state jurisdictions. The Company’s tax years from inception are subject to examination by the United States and California authorities due to the carryforwards of unutilized net operating losses (NOLs) and research and development credits.

Share-Based Compensation

Share-Based Compensation

Share-based compensation expense for stock option grants, restricted stock awards and employee stock purchase plan shares is recorded at the estimated fair value of the award as of the grant date and is recognized as expense on a straight-line basis over the requisite service period of the stock-based award. The estimation of stock options, restricted stock awards and employee stock purchase plan fair value requires management to make estimates and judgments about, among other things, employee exercise behavior, forfeiture rates and volatility of the Company’s common stock. The judgments directly affect the amount of compensation expense that will be recognized.

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, without consideration for common stock equivalents. 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 during the period. Common stock equivalents are only included when their effect is dilutive. The Company’s potentially dilutive securities, which include warrants and outstanding stock options and restricted stock awards under the stock compensation plans, have been excluded from the computation of diluted net loss per share as they would be anti-dilutive. For all periods presented, there is no difference in the number of shares used to compute basic and diluted shares outstanding due to the Company’s net loss position.

The following table sets forth the outstanding potentially dilutive securities that have been excluded in the calculation of diluted net loss per share because to do so would be anti-dilutive.

	March 31,
	2017		2016
Warrants for common stock		71,257		71,257

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02 (“ASU 2016-02”), Leases. ASU 2016-02 requires that lessees recognize assets and liabilities for the rights and obligations for leases with a lease term of more than one year. The amendments in this ASU are effective for annual periods ending after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In March 2016, the FASB issued ASU 2016-09 (“ASU 2016-09”), Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 simplifies several aspects of the accounting for employee share-based payments, including accounting for income taxes, forfeitures, statutory tax withholding requirements, and classification on the statement of cash flows. The amendments in this ASU are effective for annual periods beginning after December 15, 2016. Early adoption is permitted. The Company is evaluating the impact of adoption on its financial statements.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. This pronouncement gives guidance to clarify how certain cash receipts and payments should be presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the timing of adoption of this guidance and the impact of the adoption of this guidance on its financial statements.

In November 2016, the Financial Accounting Standards Board (the “FASB) issued Accounting Standards Update (or “ASU”) No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (ASU 2016-18), which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This guidance was effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Adoption of this guidance did not have an impact on our financial position or results of operations.
