Accounting Policies [Abstract]  
Basis of Accounting, Policy [Policy Text Block]
Basis of Presentation
The accompanying unaudited interim condensed financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, the unaudited interim condensed financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Certain information and footnote disclosures normally included in the Company’s annual financial statements prepared in accordance with GAAP have been condensed or omitted. These condensed financial statement results are not necessarily indicative of results to be expected for the full fiscal year or any future period.
Therefore, these condensed financial statements should be read in conjunction with the Company's audited financial statements and notes thereto for the year ended December 31, 2016, which were included in the Company’s Form 10-12 G/A, as amended, and filed with the U.S. Securities and Exchange Commission (“SEC”) on March 27, 2017. The results of operations for any interim periods are not necessarily indicative of the results that may be expected for the entire fiscal year or any other interim period.
The condensed financial statements may not be indicative of future performance and may not reflect what the results of operations, financial position, and cash flows would have been had Avenue operated as an independent entity. Certain estimates, including allocations from Fortress, have been made to provide financial statements for stand-alone reporting purposes. All inter-company transactions between Fortress and Avenue are classified as accrued expenses - related party in the financial statements. The Company believes that the assumptions underlying the financial statements are reasonable. The cost allocation methods applied to certain common costs include the following:
Specific identification.  Where the amounts were specifically identified to Avenue, they were classified accordingly.
Reasonable allocation.  Where the amounts were not clearly or specifically identified, management determined if a reasonable allocation method could be applied. 
Reverse stock split
On June 26, 2017, the Company effected a 3.0-to-1.0 reverse stock split of Company's common stock. No fractional shares were issued in connection with the stock split. The par value and other terms of these classes of stock were not affected by the reverse stock split.
All share and per share amounts, including stock options, have been retroactively adjusted in these condensed financial statements for all periods presented to reflect the 3.0-to-1.0 reverse stock split. Further, the fair value of stock issuances has been retroactively adjusted in these unaudited condensed financial statements for all periods presented to reflect the 3.0-to-1.0 reverse stock split.
Use of Estimates, Policy [Policy Text Block]
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
Cash and Cash Equivalents, Policy [Policy Text Block]
Cash and Cash Equivalents
The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents at September 30, 2017 and at December 31, 2016 consisted of cash, money market funds and certificates of deposit in institutions in the United States. Balances at certain institutions have exceeded Federal Deposit Insurance Corporation (“FDIC”) insured limits and U.S. government agency securities.
Investment, Policy [Policy Text Block]
Short-term Investments – Held to Maturity
The company classifies its certificates of deposit as held to maturity in accordance with the Financial Accounting Standards Board ("FASB") Accounting Standards Codification (“ASC”) 320,  Investments – Debt and Equity Securities. The Company considers all short-term investments with an original maturity in excess of three months when purchased to be short-term investments. In July 2017 and in September 2017, the Company purchased $5.0 million of certificates of deposit with an original maturity of six months. At September 30, 2017, the Company had approximately $10.0 million in certificates of deposit. The Company reassesses the appropriateness of the classification of its investments at the end of each reporting period. The Company has determined that its certificates of deposits with an original maturity of six months should be classified as held-to-maturity as of September 30, 2017. There were no investments as of December 31, 2016. This classification was based upon management’s determination that it has the positive intent and ability to hold the securities until their maturity dates, as its investments mature within one year and the underlying cash invested in these securities is not required for current operations.
Investments consist of short-term FDIC insured certificates of deposit carried at amortized cost using the effective interest method. The cost of the Company’s certificates of deposit approximated fair value.
Research and Development Expense, Policy [Policy Text Block]
Research and Development
Research and development costs are expensed as incurred. Advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made. Upfront and milestone payments due to third parties that perform research and development services on the Company’s behalf will be expensed as services are rendered or when the milestone is probable. Costs incurred in obtaining technology licenses are charged to research and development expense if the technology licensed has not reached technological feasibility and has no alternative future use.
Research and development costs primarily consist of personnel related expenses, including salaries, benefits, travel, and other related expenses, stock-based compensation, payments made to third parties for license and milestone costs related to in-licensed products and technology, payments made to third party contract research organizations for preclinical and clinical studies, investigative sites for clinical trials, consultants, the cost of acquiring and manufacturing clinical trial materials, costs associated with regulatory filings and patents, laboratory costs and other supplies.
Costs incurred in obtaining technology licenses are charged to research and development expense if the technology licensed has not reached commercial feasibility and has no alternative future use. The licenses purchased by the Company require substantial completion of research and development, regulatory and marketing approval efforts in order to reach commercial feasibility and has no alternative future use. Accordingly, the total purchase price for the licenses acquired are reflected as research and development - licenses acquired on the Company’s Condensed Statement of Operations.
Stockholders' Equity, Policy [Policy Text Block]
Annual Stock Dividend
In July 2016, in connection with the Amended and Restated Articles of Incorporation, the Company issued 250,000 Class A preferred shares to Fortress. The Class A preferred shares entitle the holder to a stock dividend equal to 2.5% of the fully diluted outstanding equity of the Company.
At December 31, 2016, the Company recorded the Annual Stock Dividend due to Fortress as contingent consideration. Contingent consideration is recorded when probable and reasonably estimable. The Company’s future share prices cannot be estimated due to the nature of its assets and the Company’s stage of development. Due to these uncertainties, the Company concluded that it could not reasonably estimate the contingent consideration until shares were actually issued on February 17, 2017. Because the issuance of shares on February 17, 2017 occurred prior to the issuance of the December 31, 2016 financial statements, the Company recorded approximately $49,000 in research and development - licenses acquired for the year ended December 31, 2016. On March 13, 2017, the Company issued the 87,698 common shares to Fortress and recorded an approximately $49,000 decrease in common shares issuable and a corresponding increase in additional paid in capital to account for the issuance of the PIK dividend.
Fair Value Measurement, Policy [Policy Text Block]
Fair Value Measurement
The Company follows accounting guidance on fair value measurements for financial assets and liabilities measured at fair value on a recurring basis. Under the accounting guidance, fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability.
The accounting guidance requires fair value measurements be classified and disclosed in one of the following three categories:
Level 1: Quoted prices in active markets for identical assets or liabilities.
Level 2: Observable inputs other than Level 1 prices, for similar assets or liabilities that are directly or indirectly observable in the marketplace.
Level 3: Unobservable inputs which are supported by little or no market activity and that are financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation.
The fair value hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]
Stock-Based Compensation
The Company expenses stock-based compensation to employees and board members over the requisite service period based on the estimated grant-date fair value of the awards. Stock-based awards with graded-vesting schedules are recognized on a straight-line basis over the requisite service period for each separately vesting portion of the award. For stock-based compensation awards to non-employees, the Company measures the fair value of the non-employee awards at each reporting period prior to vesting and finally at the vesting date of the award. Changes in the estimated fair value of these non-employee awards are recognized as compensation expense in the period of change.
The assumptions used in calculating the fair value of stock-based awards represent management’s best estimates and involve inherent uncertainties and the application of management’s judgment.
Derivatives, Reporting of Derivative Activity [Policy Text Block]
Valuation of Warrant Related to NSC Note
In accordance with ASC 815 Derivatives and Hedging, the Company classified the fair value of the warrant (“Contingently Issuable Warrants”) that it may be obligated to issue to National Securities, Inc. (“NSC”), in connection with the transfer on October 31, 2015 of $3.0 million of indebtedness to NSC, as a derivative liability as there was a potential that the Company would not have a sufficient number of authorized common shares available to settle this instrument. The Company valued these Contingently Issuable Warrants using a Black-Scholes model and used estimates for an expected dividend yield, a risk-free interest rate, and expected volatility together with management’s estimate of the probability of issuance of the Contingently Issuable Warrants. At each reporting period, as long as the Contingently Issuable Warrants were potentially issuable and there was a potential for an insufficient number of authorized shares available to settle the Contingently Issuable Warrants, the Contingently Issuable Warrants should be revalued and any difference from the previous valuation date would be recognized as a change in fair value in the Company’s statement of operations. On June 26, 2017, the warrants were issued (See Note 6).
Income Tax, Policy [Policy Text Block]
Income Taxes
For purposes of these financial statements, the Company’s income tax expense and deferred tax balances have been recorded as if it filed tax returns on a stand-alone basis separate from Fortress.
Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities measured at the enacted tax rates in effect for the year in which these items are expected to reverse. Deferred tax assets are reduced by valuation allowances if, based on the consideration of all available evidence, it is more likely than not that some portion or all of the deferred tax asset will not be realized.
Earnings Per Share, Policy [Policy Text Block]
Net loss per Share
Loss per share is computed by dividing net loss by the weighted-average number of common shares outstanding, excluding unvested restricted stock, during the period. Since dividends are declared paid and set aside among the holders of shares of common stock and Class A common stock pro-rata on an as-if-converted basis, the two-class method of computing net loss per share is not required. In the calculation of diluted loss per share, since there were no option or warrants as well as the conversion of rights, the diluted loss per share equaled the basic loss per share during the period. Securities that could potentially result in diluted loss per share in the future that were not included in the computation of diluted loss per share at September 30, 2017 consist of 127,488 warrants, 714,999 unvested restricted stock units and awards and 20,000 options. Securities that could potentially result in diluted loss per share in the future that were not included in the computation of diluted loss per share at September 30, 2016 consist of 274,999 unvested restricted stock awards.
New Accounting Pronouncements, Policy [Policy Text Block]
Recently Adopted Accounting Standards
In August 2014, the FASB issued Accounting Standard Update (“ASU”) 2014-15, Presentation of Financial Statements - Going Concern (Topic 915): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (“ASU 2014-15”). ASU 2014-15 states that in connection with preparing financial statements for each annual and interim reporting period, an entity's management should evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued (or within one year after the date that the financial statements are available to be issued when applicable). ASU 2014-15 will be effective for annual and interim periods beginning on or after December 15, 2016. The Company adopted ASU No. 2014-15 2016, and its adoption did not have a material impact on the Company’s condensed financial statements.
In March 2016, the FASB issued ASU No. 2016-09 Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). Under ASU 2016-09, companies will no longer record excess tax benefits and certain tax deficiencies in additional paid-in capital (“APIC”). Instead, they will record all excess tax benefits and tax deficiencies as income tax expense or benefit in the income statement and the APIC pools will be eliminated. In addition, ASU 2016-09 eliminates the requirement that excess tax benefits be realized before companies can recognize them. ASU 2016-09 also requires companies to present excess tax benefits as an operating activity on the statement of cash flows rather than as a financing activity. Furthermore, ASU 2016-09 will increase the amount an employer can withhold to cover income taxes on awards and still qualify for the exception to liability classification for shares used to satisfy the employer’s statutory income tax withholding obligation. An employer with a statutory income tax withholding obligation will now be allowed to withhold shares with a fair value up to the amount of taxes owed using the maximum statutory tax rate in the employee’s applicable jurisdiction(s). ASU 2016-09 requires a company to classify the cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation as a financing activity on the statement of cash flows. Under current GAAP, it was not specified how these cash flows should be classified. In addition, companies will now have to elect whether to account for forfeitures on share-based payments by (1) recognizing forfeitures of awards as they occur or (2) estimating the number of awards expected to be forfeited and adjusting the estimate when it is likely to change, as is currently required. The Amendments of this ASU are effective for reporting periods beginning after December 15, 2016, with early adoption permitted but all of the guidance must be adopted in the same period. The Company adopted ASU 2016-09 in the first quarter of 2017, and its adoption did not have a material impact on the Company’s condensed financial statements.
Recently Issued Accounting Standards
In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. It is effective prospectively for the annual period ending December 31, 2018 and interim periods within that annual period. Early adoption is permitted. The Company is currently evaluating the impact of adopting this standard on the financial statements and disclosures, but does not expect it to have a significant impact.
In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), Derivatives and Hedging (Topic 815). The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down round features. When determining whether certain financial instruments should be classified as liabilities or equity instruments, a down round feature no longer precludes equity classification when assessing whether the instrument is indexed to an entity’s own stock. The amendments also clarify existing disclosure requirements for equity-classified instruments. As a result, a freestanding equity-linked financial instrument (or embedded conversion option) no longer would be accounted for as a derivative liability at fair value as a result of the existence of a down round feature. For freestanding equity classified financial instruments, the amendments require entities that present earnings per share (EPS) in accordance with Topic 260 to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features are now subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Codification, to a scope exception. Those amendments do not have an accounting effect. For public business entities, the amendments in Part I of this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For all other entities, the amendments in Part I of this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted for all entities, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company is currently evaluating the impact of adopting this standard on the financial statements and disclosures.
