Accounting Policies [Abstract]
ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Text Block]	NOTE 1 – ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES *Description of Business* We are a biopharmaceutical company focused on the acquisition, development and commercialization of innovative and medically important pharmaceutical products for the treatment of cancer and other underserved therapeutic needs. We aim to acquire rights to these technologies by licensing or otherwise acquiring an ownership interest, funding their research and development and eventually either out-licensing or bringing the technologies to market. Currently, the Company is developing two advanced therapies targeting hematological malignancies. TG-1101 (ublituximab), is a novel, third generation monoclonal antibody that targets a specific and unique epitope on the CD20 antigen found on mature B-lymphocytes. We are also developing TGR-1202, a highly specific, orally available PI3K delta inhibitor. We also hold the development rights to AST-726, a nasally delivered product for the treatment of Vitamin B₁₂ deficiency, and AST-915, an orally delivered treatment for essential tremor. The accompanying unaudited condensed consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they may not include all of the information and footnotes required by GAAP for complete financial statements. All adjustments that are, in the opinion of management, of a normal recurring nature and are necessary for a fair presentation of the consolidated financial statements have been included. Nevertheless, these consolidated financial statements should be read in conjunction with the audited consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2011. The results of operations for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the entire fiscal year or any other interim period. On December 29, 2011, the Company entered into and consummated an exchange transaction agreement (the “Exchange Transaction”) with Opus Point Partners, LLC (“Opus”) and TG Biologics, Inc. (formerly known as TG Therapeutics, Inc.) (“TG Bio”). The stockholders of TG Bio received the majority of the voting shares of the Company; therefore, the merger was accounted for as a reverse acquisition whereby TG Bio was the accounting acquirer (legal acquiree) and the Company was the accounting acquiree (legal acquirer) under the acquisition method of accounting. TG Bio was incorporated in Delaware in November 2010, but did not commence operations until April 2011. On April 30, 2012, the Company filed a Certificate of Amendment to its Certificate of Incorporation to change its name from Manhattan Pharmaceuticals, Inc. (“Manhattan”) to TG Therapeutics, Inc. In conjunction with this change, the subsidiary formerly named TG Therapeutics, Inc. filed a Certificate of Amendment changing its name to TG Biologics, Inc. *Liquidity and Capital Resources* We have incurred operating losses since our inception and expect to continue to incur operating losses for the foreseeable future and may never become profitable. As of September 30, 2012, we have an accumulated deficit of $15,466,056, including non-cash licensing and non-cash compensations expenses of approximately $19,140,000, prior to the allocation of noncontrolling interest. Our primary source of cash has been proceeds from the private placement of equity securities. We have not yet commercialized any of our drug candidates and cannot be sure if we will ever be able to do so. Even if we commercialize one or more of our drug candidates, we may not become profitable. Our ability to achieve profitability depends on a number of factors, including our ability to obtain regulatory approval for our drug candidates, successfully complete any post-approval regulatory obligations and successfully commercialize our drug candidates alone or in partnership. We may continue to incur substantial operating losses even if we begin to generate revenues from our drug candidates. On December 30, 2011, we completed the first closing of the private placement of our securities, issuing 4,929,523 shares of Company $0.001 par value common stock (“Common Stock “) at a price per share of $2.25 for total gross proceeds, before placement commissions and expenses, of $11,091,425 (the “2011 Equity PIPE”). Investors also received warrants to purchase 1,232,381 shares of Common Stock. The warrants have an exercise price of $2.25 per share and are exercisable for five years. In 2012, we completed two additional closings of the 2011 Equity PIPE. These closings were held on January 31, 2012, and February 24, 2012. In these closings, the Company issued 695,428 shares of our Series A preferred stock (“Company Preferred Stock”) at a price per share of $20.00, for total gross proceeds, before placement commissions and expenses, of $13,908,560. Each share of Company Preferred Stock was convertible into 8.89 shares of Common Stock, provided that such conversion rights were subject to sufficient available authorized shares of Common Stock. In connection with the reverse stock split effected by the Company on April 30, 2012 (as discussed below), all shares of preferred stock issued in the 2011 Equity PIPE were converted to Common Stock. Investors also received warrants to purchase 1,545,396 shares of Common Stock. The warrants have an exercise price of $2.25 per share and are exercisable for five years. The shares of Company Preferred Stock and warrants sold in these closings were offered and sold to accredited investors, including members of management, without registration under the Securities Act, or state securities laws, in reliance on the exemptions provided by Section 4(2) of the Securities Act, and Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. Accordingly, the securities issued in the Offering have not been registered under the Securities Act, and until so registered, these securities may not be offered or sold in the United States absent registration or availability of an applicable exemption from registration. Our Common Stock is quoted on the OTC Bulletin Board and trades under the symbol “TGTX.” *Reverse Stock Split* On April 30, 2012, the Company effected a reverse split of its Common Stock at a ratio of 56.25 for 1, pursuant to a previously obtained stockholder authorization. All share amounts and per share prices in this Quarterly Report on Form 10-Q have been retroactively adjusted to reflect the effect of our reverse stock split, on a fifty six and one quarter (56.25) for one (1) basis, unless otherwise indicated. The exercise price for all stock options and warrants and the conversion price for convertible securities in the accompanying condensed consolidated financial statements have been adjusted to reflect the reverse stock split by multiplying the original exercise or conversion price by fifty six and one quarter (56.25). *Cash and Cash Equivalents* We treat liquid investments with original maturities of less than three months when purchased as cash and cash equivalents. *Research and Development Costs* Generally, research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are delivered or the related services are performed, subject to an assessment of recoverability. We make estimates of costs incurred in relation to external clinical research organizations, or CROs, and clinical site costs. We analyze the progress of clinical trials, including levels of patient enrollment, invoices received and contracted costs when evaluating the adequacy of the amount expensed and the related prepaid asset and accrued liability. Significant judgments and estimates must be made and used in determining the accrued balance and expense in any accounting period. We review and accrue CRO expenses and clinical trial study expenses based on work performed and rely upon estimates of those costs applicable to the stage of completion of a study. Accrued CRO costs are subject to revisions as such trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known. With respect to clinical site costs, the financial terms of these agreements are subject to negotiation and vary from contract to contract. Payments under these contracts may be uneven, and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of portions of the clinical trial or similar conditions. The objective of our policy is to match the recording of expenses in our financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical site costs are recognized based on our estimate of the degree of completion of the event or events specified in the specific clinical study or trial contract. *In-Process Research and Development* Acquired research and development projects are recorded at their fair value as of the date of acquisition. The fair values are assessed annually in the fourth quarter, or sooner, if there is an indicator of impairment, to ascertain if there has been any impairment of the recorded value. If there is an impairment, the asset is written down to its current fair value by the recording of an expense. Impairment testing consists of a comparison of the fair value of the in-process research and development with its carrying amount. *Income Taxes* Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. If the likelihood of realizing the deferred tax assets or liability is less than “more likely than not,” a valuation allowance is then created. We, and our subsidiaries, file income tax returns in the U.S. Federal jurisdiction and in various states. We have net operating loss carryforwards that are subject to examination for a number of years beyond the year in which they were generated. Since a portion of these net operating loss carryforwards may be utilized in the future, many of these net operating loss carryforwards will remain subject to examination. We recognize interest and penalties related to uncertain income tax positions in income tax expense. *Stock-Based Compensation* We recognize all share-based payments to employees and to non-employee directors for service on our board of directors as compensation expense in the consolidated financial statements based on the fair values of such payments. Stock-based compensation expense recognized each period is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. For share-based payments to consultants and other third-parties, compensation expense is determined at the “measurement date.” The expense is recognized over the vesting period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. We record compensation expense based on the fair value of the award at the reporting date. The awards to consultants and other third-parties are then revalued, or the total compensation is recalculated based on the then current fair value, at each subsequent reporting date. *Basic and Diluted Net (Loss) Income Per Share of Common Stock* Basic net income (loss) per share of Common Stock is calculated by dividing net income (loss) applicable to Common Stock by the weighted-average number of shares of Common Stock outstanding for the period. Diluted net loss per share of Common Stock is the same as basic net income (loss) per share of Common Stock since potentially dilutive securities from stock options, stock warrants and convertible preferred stock would have an antidilutive effect either because the Company incurred a net loss during the period presented or because such potentially dilutive securities were out of the money and the Company realized net income during the period presented. The amounts of potentially dilutive securities excluded from the calculation were 7,484,689 at September 30, 2012. During the three and nine months ended September 30, 2012, the Company incurred a net loss; therefore, all of the dilutive securities are excluded from the computation of diluted earnings per share. *Impairment* Long lived assets are reviewed for an impairment loss when circumstances indicate that the carrying value of long-lived tangible and intangible assets with finite lives may not be recoverable. Management’s policy in determining whether an impairment indicator exists, a triggering event, comprises measurable operating performance criteria as well as qualitative measures. If an analysis is necessitated by the occurrence of a triggering event, we make certain assumptions in determining the impairment amount. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the difference between the carrying value and the estimated fair value. Goodwill is reviewed for impairment annually or when events arise that could indicate that an impairment exists. We test for goodwill impairment using a two-step process. The first step compares the fair value of the reporting unit with the unit's carrying value, including goodwill. When the carrying value of the reporting unit is greater than fair value, the unit’s goodwill may be impaired, and the second step must be completed to measure the amount of the goodwill impairment charge, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the unit’s goodwill. If the carrying amount is greater than the implied fair value, the carrying value of the goodwill must be written down to its implied fair value. We will continue to perform impairment tests annually at December 31 and whenever events or changes in circumstances suggest that the carrying value of goodwill may not be recoverable.

Liquidity and Capital Resources

We have incurred operating losses since our inception and expect to continue to incur operating losses for the foreseeable future and may never become profitable. As of September 30, 2012, we have an accumulated deficit of $15,466,056, including non-cash licensing and non-cash compensations expenses of approximately $19,140,000, prior to the allocation of noncontrolling interest.

Our primary source of cash has been proceeds from the private placement of equity securities. We have not yet commercialized any of our drug candidates and cannot be sure if we will ever be able to do so. Even if we commercialize one or more of our drug candidates, we may not become profitable. Our ability to achieve profitability depends on a number of factors, including our ability to obtain regulatory approval for our drug candidates, successfully complete any post-approval regulatory obligations and successfully commercialize our drug candidates alone or in partnership. We may continue to incur substantial operating losses even if we begin to generate revenues from our drug candidates.

On December 30, 2011, we completed the first closing of the private placement of our securities, issuing 4,929,523 shares of Company $0.001 par value common stock (“Common Stock “) at a price per share of $2.25 for total gross proceeds, before placement commissions and expenses, of $11,091,425 (the “2011 Equity PIPE”). Investors also received warrants to purchase 1,232,381 shares of Common Stock. The warrants have an exercise price of $2.25 per share and are exercisable for five years.

In 2012, we completed two additional closings of the 2011 Equity PIPE. These closings were held on January 31, 2012, and February 24, 2012. In these closings, the Company issued 695,428 shares of our Series A preferred stock (“Company Preferred Stock”) at a price per share of $20.00, for total gross proceeds, before placement commissions and expenses, of $13,908,560. Each share of Company Preferred Stock was convertible into 8.89 shares of Common Stock, provided that such conversion rights were subject to sufficient available authorized shares of Common Stock. In connection with the reverse stock split effected by the Company on April 30, 2012 (as discussed below), all shares of preferred stock issued in the 2011 Equity PIPE were converted to Common Stock. Investors also received warrants to purchase 1,545,396 shares of Common Stock. The warrants have an exercise price of $2.25 per share and are exercisable for five years. The shares of Company Preferred Stock and warrants sold in these closings were offered and sold to accredited investors, including members of management, without registration under the Securities Act, or state securities laws, in reliance on the exemptions provided by Section 4(2) of the Securities Act, and Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. Accordingly, the securities issued in the Offering have not been registered under the Securities Act, and until so registered, these securities may not be offered or sold in the United States absent registration or availability of an applicable exemption from registration.

Our Common Stock is quoted on the OTC Bulletin Board and trades under the symbol “TGTX.”

Reverse Stock Split

On April 30, 2012, the Company effected a reverse split of its Common Stock at a ratio of 56.25 for 1, pursuant to a previously obtained stockholder authorization. All share amounts and per share prices in this Quarterly Report on Form 10-Q have been retroactively adjusted to reflect the effect of our reverse stock split, on a fifty six and one quarter (56.25) for one (1) basis, unless otherwise indicated. The exercise price for all stock options and warrants and the conversion price for convertible securities in the accompanying condensed consolidated financial statements have been adjusted to reflect the reverse stock split by multiplying the original exercise or conversion price by fifty six and one quarter (56.25).

Cash and Cash Equivalents

We treat liquid investments with original maturities of less than three months when purchased as cash and cash equivalents.

Research and Development Costs

Generally, research and development costs are expensed as incurred. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are deferred and amortized over the period that the goods are delivered or the related services are performed, subject to an assessment of recoverability. We make estimates of costs incurred in relation to external clinical research organizations, or CROs, and clinical site costs. We analyze the progress of clinical trials, including levels of patient enrollment, invoices received and contracted costs when evaluating the adequacy of the amount expensed and the related prepaid asset and accrued liability. Significant judgments and estimates must be made and used in determining the accrued balance and expense in any accounting period. We review and accrue CRO expenses and clinical trial study expenses based on work performed and rely upon estimates of those costs applicable to the stage of completion of a study. Accrued CRO costs are subject to revisions as such trials progress to completion. Revisions are charged to expense in the period in which the facts that give rise to the revision become known. With respect to clinical site costs, the financial terms of these agreements are subject to negotiation and vary from contract to contract. Payments under these contracts may be uneven, and depend on factors such as the achievement of certain events, the successful recruitment of patients, the completion of portions of the clinical trial or similar conditions. The objective of our policy is to match the recording of expenses in our financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical site costs are recognized based on our estimate of the degree of completion of the event or events specified in the specific clinical study or trial contract.

In-Process Research and Development

Acquired research and development projects are recorded at their fair value as of the date of acquisition. The fair values are assessed annually in the fourth quarter, or sooner, if there is an indicator of impairment, to ascertain if there has been any impairment of the recorded value. If there is an impairment, the asset is written down to its current fair value by the recording of an expense. Impairment testing consists of a comparison of the fair value of the in-process research and development with its carrying amount.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period that includes the enactment date. If the likelihood of realizing the deferred tax assets or liability is less than “more likely than not,” a valuation allowance is then created.

We, and our subsidiaries, file income tax returns in the U.S. Federal jurisdiction and in various states. We have net operating loss carryforwards that are subject to examination for a number of years beyond the year in which they were generated. Since a portion of these net operating loss carryforwards may be utilized in the future, many of these net operating loss carryforwards will remain subject to examination.

We recognize interest and penalties related to uncertain income tax positions in income tax expense.

Stock-Based Compensation

We recognize all share-based payments to employees and to non-employee directors for service on our board of directors as compensation expense in the consolidated financial statements based on the fair values of such payments. Stock-based compensation expense recognized each period is based on the value of the portion of share-based payment awards that is ultimately expected to vest during the period. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

For share-based payments to consultants and other third-parties, compensation expense is determined at the “measurement date.” The expense is recognized over the vesting period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. We record compensation expense based on the fair value of the award at the reporting date. The awards to consultants and other third-parties are then revalued, or the total compensation is recalculated based on the then current fair value, at each subsequent reporting date.

Basic and Diluted Net (Loss) Income Per Share of Common Stock

Basic net income (loss) per share of Common Stock is calculated by dividing net income (loss) applicable to Common Stock by the weighted-average number of shares of Common Stock outstanding for the period. Diluted net loss per share of Common Stock is the same as basic net income (loss) per share of Common Stock since potentially dilutive securities from stock options, stock warrants and convertible preferred stock would have an antidilutive effect either because the Company incurred a net loss during the period presented or because such potentially dilutive securities were out of the money and the Company realized net income during the period presented. The amounts of potentially dilutive securities excluded from the calculation were 7,484,689 at September 30, 2012. During the three and nine months ended September 30, 2012, the Company incurred a net loss; therefore, all of the dilutive securities are excluded from the computation of diluted earnings per share.

Impairment

Long lived assets are reviewed for an impairment loss when circumstances indicate that the carrying value of long-lived tangible and intangible assets with finite lives may not be recoverable. Management’s policy in determining whether an impairment indicator exists, a triggering event, comprises measurable operating performance criteria as well as qualitative measures. If an analysis is necessitated by the occurrence of a triggering event, we make certain assumptions in determining the impairment amount. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the difference between the carrying value and the estimated fair value.

Goodwill is reviewed for impairment annually or when events arise that could indicate that an impairment exists. We test for goodwill impairment using a two-step process. The first step compares the fair value of the reporting unit with the unit's carrying value, including goodwill. When the carrying value of the reporting unit is greater than fair value, the unit’s goodwill may be impaired, and the second step must be completed to measure the amount of the goodwill impairment charge, if any. In the second step, the implied fair value of the reporting unit’s goodwill is compared with the carrying amount of the unit’s goodwill. If the carrying amount is greater than the implied fair value, the carrying value of the goodwill must be written down to its implied fair value. We will continue to perform impairment tests annually at December 31 and whenever events or changes in circumstances suggest that the carrying value of goodwill may not be recoverable.
