Accounting Policies [Abstract]
Description of Business, Basis of Presentation and Going Concern	Note 1: Description of Business, Basis of Presentation and Going Concern Description of Business vTv Therapeutics Inc. (the “Company,” the “Registrant,” “we” or “us”) was incorporated in the state of Delaware in April 2015. The Company is a clinical-stage pharmaceutical company focused on treating metabolic diseases to minimize their long-term complications through end-organ protection. Principles of Consolidation vTv Therapeutics Inc. is a holding company and its principal asset is a controlling equity interest in vTv Therapeutics LLC (“vTv LLC”), the Company’s principal operating subsidiary, which is a clinical-stage pharmaceutical company focused on treating metabolic diseases to minimize their long-term complications through end-organ protection. The Company has determined that vTv LLC is a variable-interest entity (“VIE”) for accounting purposes and that vTv Therapeutics Inc. is the primary beneficiary of vTv LLC because (through its managing member interest in vTv LLC and the fact that the senior management of vTv Therapeutics Inc. is also the senior management of vTv LLC) it has the power and benefits to direct all of the activities of vTv LLC, which include those that most significantly impact vTv LLC’s economic performance. vTv Therapeutics Inc. has therefore consolidated vTv LLC’s results pursuant to Accounting Standards Codification Topic 810, “Consolidation” in its Condensed Consolidated Financial Statements. As of June 30, 2020, various holders own non-voting interests in vTv LLC, representing a 32.5% economic interest in vTv LLC, effectively restricting vTv Therapeutics Inc.’s interest to 67.5% of vTv LLC’s economic results, subject to increase in the future, should vTv Therapeutics Inc. purchase additional non-voting common units (“vTv Units”) of vTv LLC, or should the holders of vTv Units decide to exchange such units (together with shares of Class B Common Stock) for shares of Class A Common Stock (or cash) pursuant to the Exchange Agreement (as defined in Note 10). vTv Therapeutics Inc. has provided financial and other support to vTv LLC in the form of its purchase of vTv Units with the net proceeds of the Company’s initial public offering (“IPO”) in 2015 and its registered direct offering in March 2019, its agreeing to be a co-borrower under the Venture Loan and Security Agreement (the “Loan Agreement”) with Horizon Technology Finance Corporation and Silicon Valley Bank (together, the “Lenders”) which was entered into in 2016, and its entrance into the letter agreements, dated as of December 5, 2017, July 30, 2018, December 11, 2018, March 18, 2019, September 26, 2019 and December 23, 2019 with MacAndrews and Forbes Group LLC (the “Letter Agreements”). vTv Therapeutics Inc. will not be required to provide financial or other support for vTv LLC outside of its obligations pertaining to the Loan Agreement as a co-borrower. However, vTv Therapeutics Inc. will control its business and other activities through its managing member interest in vTv LLC, and its management is the management of vTv LLC. The creditors of vTv LLC do not have any recourse to the general credit of vTv Therapeutics Inc. except as allowed under the provisions of the Loan Agreement. Nevertheless, because vTv Therapeutics Inc. will have no material assets other than its interests in vTv LLC, any financial difficulties at vTv LLC could result in vTv Therapeutics Inc. recognizing a loss. Going Concern and Liquidity To date, the Company has not generated any product revenue and has not achieved profitable operations. The continuing development of our drug candidates will require additional financing. From its inception through June 30, 2020, the Company has funded its operations primarily through a combination of private placements of common and preferred equity, research collaboration agreements, upfront and milestone payments for license agreements, debt and equity financings and the completion of its IPO in August 2015. As of June 30, 2020, the Company had an accumulated deficit of $268.9 million and has generated net losses in each year of its existence. As of June 30, 2020, the Company’s liquidity sources included cash and cash equivalents of $6.4 million and $3.0 million of remaining funds available under the Letter Agreements. Further, we have remaining availability of $5.4 million under our Controlled Equity Offering SM The Company’s financial statements have been prepared assuming the Company will continue as a going concern, which contemplates, among other things, the realization of assets and satisfaction of liabilities in the normal course of business. The Condensed Consolidated Financial Statements do not include adjustments to reflect the possible future effects on the recoverability and classification of recorded assets or the amounts of liabilities that might be necessary should the Company be unable to continue as a going concern. The full extent to which the COVID-19 outbreak / pandemic will directly or indirectly impact our business, results of operations and financial condition, including licensing revenues, expenses, reserves and allowances, manufacturing, clinical trials, research and development costs and employee-related amounts will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international suppliers and markets.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2: Summary of Significant Accounting Policies Unaudited Interim Financial Information The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying Condensed Consolidated Balance Sheet as of June 30, 2020, Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2020 and 2019, Condensed Consolidated Statement of Changes in Redeemable Noncontrolling Interest and Stockholders’ Deficit for the three and six months ended June 30, 2020 and 2019 and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2020 and 2019 are unaudited. These unaudited financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited financial statements and the accompanying notes for the year ended December 31, 2019 contained in the Company’s Annual Report on Form 10-K. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019 and cash flows for the six months ended June 30, 2020 and 2019. The December 31, 2019 Condensed Consolidated Balance Sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements. The financial data and other information disclosed in these notes to the financial statements related to the three and six months ended June 30, 2020 and 2019 are unaudited. Interim results are not necessarily indicative of results for an entire year. The Company does not have any components of other comprehensive income recorded within its Condensed Consolidated Financial Statements, and, therefore, does not separately present a statement of comprehensive income in its Condensed Consolidated Financial Statements. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to the grant date fair value of equity awards, the fair value of warrants to purchase shares of its Class A Common Stock, the fair value of the Class B Common Stock, the useful lives of property and equipment, the fair value of derivative liabilities, and the fair value of the Company’s debt, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable, the results of which form the basis for making judgments about the carrying value of assets and liabilities. Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash on deposit with multiple financial institutions. The balances of these cash accounts frequently exceed insured limits. Three customers represented 100% of the revenue earned during the three and six months ended June 30, 2019. Revenue for the three and six months ended June 30, 2020 was insignificant. Cash and Cash Equivalents The Company considers any highly liquid investments with an original maturity of three months or less to be cash and cash equivalents. Restricted Cash and Cash Equivalents Restricted cash and cash equivalents as of December 31, 2019 was $2.5 million. This amount relates to the minimum balance that the Company was required to maintain in a deposit account that was pledged to secure the Loan Agreement and was subject to an account control agreement pursuant to the Loan Agreement. There was no restricted cash and cash equivalents as of June 30, 2020, as the Loan Agreement was amended to remove the minimum cash balance requirements (See Note 5 for further details). The following table provides a reconciliation of cash, cash equivalents and restricted cash and cash equivalents reported within the Condensed Consolidated Balance Sheets as of June 30, 2020 and December 31, 2019 that sum to the total of the same such amounts shown in the Condensed Consolidated Statements of Cash Flows (in thousands): June 30, 2020 December 31, 2019 Cash and cash equivalents $ 6,392 $ 1,777 Restricted cash and cash equivalents — — Restricted cash and cash equivalents, long-term — 2,500 Total cash, cash equivalents and restricted cash and cash equivalents shown in the consolidated statement of cash flows $ 6,392 $ 4,277 Investments In connection with the license agreement with Reneo Pharmaceuticals, Inc. (“Reneo”) (the “Reneo License Agreement”) common stock representing a minority equity interest in Reneo No adjustments were made to the value of the Company’s investment in Reneo for the three and six months ended June 30, 2020 and 2019 either due to impairment or based on observable price changes. Revenue Recognition The Company uses the revenue recognition guidance established by ASC Topic 606, “Revenue From Contracts With Customers” (“ASC Topic 606”). The majority of the Company’s revenue results from its license and collaboration agreements associated with the development of investigational drug products. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The transaction price under the contract is determined based on the value of the consideration expected to be received in exchange for the transferred assets or services. Development, regulatory and sales milestones included in the Company’s collaboration agreements are considered to be variable consideration. The amount of variable consideration expected to be received is included in the transaction price when it becomes probable that the milestone will be met. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each performance obligation using the Company’s best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus margin approach. Revenue is recognized over the related period over which the Company expects the services to be provided using a proportional performance model or a straight-line method of recognition if there is no discernable pattern over which the services will be provided. Research and Development Major components of research and development costs include cash and share-based compensation, costs of preclinical studies, clinical trials and related clinical manufacturing, costs of drug development, costs of materials and supplies, regulatory and compliance costs, fees paid to consultants and other entities that conduct certain research and development activities on the Company’s behalf, facilities costs, and overhead costs. Research and development costs are expensed as incurred. The Company records accruals based on estimates of the services received, efforts expended, and amounts owed pursuant to contracts with numerous contract research organizations. In the normal course of business, the Company contracts with third parties to perform various clinical study activities in the ongoing development of potential products. The financial terms of these agreements are subject to negotiation and variation from contract to contract and may result in uneven payment flows. Payments under the contracts depend on factors such as the achievement of certain events and the completion of portions of the clinical study or similar conditions. The objective of the Company’s accrual policy is to match the recording of expenses in its financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical studies are recognized based on the Company’s estimate of the degree of completion of the event or events specified in the specific clinical study. The Company records nonrefundable advance payments it makes for future research and development activities as prepaid expenses. Prepaid expenses are recognized as expense in the Condensed Consolidated Statements of Operations as the Company receives the related goods or services. Research and development costs that are reimbursed under a cost-sharing arrangement are reflected as a reduction of research and development expense. Recently Issued Accounting Pronouncements There have been no recently accounting pronouncements which are expected to have a material impact on the Company’s financial statements.

Collaboration Agreements	Note 3: Collaboration Agreements Reneo License Agreement T he Company is party to the Reneo License Agreement, under which Reneo obtained an exclusive, worldwide, sublicensable license to develop and commercialize the Company’s peroxisome proliferation activated receptor delta (PPAR- δ ) agonist program, including the compound HPP593 , for therapeutic, prophylactic or diagnostic application in humans. The Company has fully allocated the transaction price to the license and the technology transfer services, which represents a single combined performance obligation because they were not capable of being distinct on their own. The revenue related to this performance obligation was recognized on a straight-line basis over the technology transfer service period. The revenue related to this performance obligation has been fully recognized as of June 30, 2020. No revenue related to this performance obligation was recognized for the three and six months ended June 30, 2020. For the three and six months ended June 30, 2019, the Company recognized revenue related to this performance obligation of $0.8 million and $1.7 million, respectively. Huadong License Agreement The Company is party to a License Agreement with Hangzhou Zhongmei Huadong Pharmaceutical Co., Ltd. (“Huadong”) (the “Huadong License Agreement”), under which Huadong obtained an exclusive and sublicensable license to develop and commercialize the Company’s glucagon-like peptide-1 receptor agonist (“GLP-1r”) program, including the compound TTP273 Under the Huadong License Agreement, the Company is also responsible for conducting a Phase 2 multi-region clinical trial (the “Phase 2 MRCT”), should Huadong require it to do so. If conducted, the Phase 2 MRCT will include sites in both the United States and Huadong License Territory for the purpose of assessing the safety and efficacy of TTP273 The significant performance obligations under this license agreement were determined to be (i) the exclusive license to develop and commercialize the Company’s GLP-1r program, (ii) technology transfer services related to the chemistry and manufacturing know-how for a defined period after the effective date, (iii) the obligation to sponsor and conduct the Phase 2 MRCT, (iv) the Company’s obligation to participate on a joint development committee (the “JDC”), and (v) other obligations considered to be de minimis in nature. The Company has determined that the license and technology transfer services related to the chemistry and manufacturing know-how represent a combined performance obligation because they were not capable of being distinct on their own. The Company also determined that there was no discernable pattern in which the technology transfer services would be provided during the transfer service period. As such, the Company recognized the revenue related to this combined performance obligation using the straight-line method over the transfer service period.

Revenue for this performance obligation will be recognized using the proportional performance model over the period during which the Company conducts the Phase 2 MRCT trial. Since the Company has not yet begun the Phase 2 MRCT trial, no revenue for this performance obligation has yet been recognized. The expectation of when, or if, the Phase 2 MRCT trial will begin remains indeterminate. The portion of the transaction price allocated to the obligation to participate in the joint development committee (the “JDC”) to oversee the development of products and the Phase 2 MRCT in accordance with the development plan remained deferred as of June 30, 2020 and revenue will be recognized using the proportional performance model over the period of the Company’s participation on the JDC. The unrecognized amount of the transaction price allocated to this performance obligation as of June 30, 2020 was $0.1 million. An immaterial amount of revenue for this performance obligation has been recognized during the six months ended June 30, 2020.

No revenue related to this performance obligation was recognized during the three and six months ended June 30, 2020. During the six months ended June 30, 2019, the transaction price for this performance obligation was increased by $1.0 million due to the satisfaction of a development milestone under the license agreement. This amount was fully recognized as revenue during the six months ended June 30, 2019, as the related performance obligation was fully satisfied. JDRF Agreement In August 2017, the Company entered into a research and collaboration agreement with JDRF International (the “JDRF Agreement”) to support the funding of the Simplici-T1 Study, a Phase 2 study to explore the effects of TTP399 TTP399 Payments that the Company receives from JDRF under this agreement will be recorded as restricted cash and current liabilities and recognized as an offset to research and development expense, based on the progress of the project, and only to the extent that the restricted cash is utilized to fund such development activities.

Share-Based Compensation	Note 4: Share-Based Compensation The Company has issued non-qualified stock option awards to certain employees of the Company. These option awards vest ratably over a three-year period and the option awards expire after a term of ten years from the date of grant. As of June 30, 2020, the Company had total unrecognized stock-based compensation expense for its outstanding stock option awards of approximately $1.2 million, which is expected to be recognized over a weighted average period of 1.8 years. The weighted average grant date fair value of option grants during the six months ended June 30, 2020 and 2019 was $2.26 and $1.94 per option, respectively. The aggregate intrinsic value of the in-the-money awards outstanding at June 30, 2020 was $0.1 million. The Company uses the Black-Scholes option pricing model to calculate the fair value of stock options granted.

On April 1, 2020, the Company entered into an amendment to the Loan Agreement (the “Second Amendment”) and on July 29, 2020, the Company entered into the Third Amendment to the Loan Agreement. These amendments extended the maturity dates of the loans and adjusted the minimum cash balance requirements and their impacts have been incorporated into these disclosures and are more fully described below. Each loan tranche bears interest at a floating rate equal to 10.5% plus the amount by which the one-month London Interbank Offer Rate (“LIBOR”) exceeds 0.5%. The Company borrowed the first tranche of $12.5 million upon close of the Loan Agreement in October 2016. The first tranche originally required only monthly interest payments until May 1, 2018 followed by equal monthly payments of principal plus accrued interest through the scheduled maturity date on May 1, 2020. In connection with the Third Amendment, the maturity date of the first tranche was extended to September 1, 2020. In addition, a final payment for the first tranche loan equal to $0.8 million originally due on May 1, 2020 was extended to September 1, 2020 as part of the Third Amendment, or such earlier date specified in the Loan Agreement. The Company borrowed the second tranche of $7.5 million in March 2017. The second tranche required only monthly interest payments until October 1, 2018 followed by equal monthly payments of principal plus accrued interest through the scheduled maturity date on October 1, 2020. In connection with the Second Amendment, the maturity date of the second tranche was extended to January 1, 2021. In addition, a final payment for the second tranche loan equal to $0.5 million was originally due on October 1, 2020, or such earlier date specified in the Loan Agreement. In connection with the Second Amendment, the due date for this final payment was extended to January 1, 2021, or such earlier date specified in the Loan Agreement. The total amount of the payment was increased to $0.8 million as a result of the Second and Third Amendments. For each of the first and second tranches, the combined Second and Third Amendment require only monthly interest payments on the outstanding principal balance for the amounts due from April 1, 2020, through August 1, 2020 If the Company repays all or a portion of the loan prior to the applicable maturity dates, as amended, it will pay the Lenders a prepayment penalty fee, based on a percentage of the then outstanding principal balance equal to 2.0%. The Company’s obligations under the Loan Agreement are secured by a first priority security interest in substantially all of its assets. The Company has granted the Lenders a first priority security interest in all of the Company’s intellectual property, subject to certain limited exceptions. The Company has agreed not to pledge or otherwise encumber its intellectual property assets, subject to certain exceptions. The Loan Agreement includes customary affirmative and restrictive covenants, including, but not limited to, restrictions on the payment of dividends or other equity distributions and the incurrence of debt or liens upon the assets of the Company or its subsidiaries. The Loan Agreement for the period beginning April 1, 2020 and ending June 30, 2020. Beginning July 1, 2020, until the repayment of the full amounts due under the Loan Agreement, the Company must maintain a minimum cash balance equal to the lesser of (i) $1.0 million or (ii) the then-current aggregate outstanding principal balance of the loans. The costs incurred in connection with the Loan Agreement, along with the allocated fair value of the common stock warrants issued upon execution of the Loan Agreement are treated as a debt discount and are offset against the carrying value of the notes payable in the Company’s Condensed Consolidated Balance Sheet as of June 30, 2020 and December 31, 2019. The Second Amendment was considered a modification to the existing agreement for accounting purposes. As such, the Company determined a new effective interest rate of 17.8% on the debt considering the remaining unamortized cost and the increase to the final payment for the second tranche. The related costs will be amortized and the final payments for the first and second loan tranches are accrued as additional interest expense, using the effective interest method over the remaining term of the Loan Agreement.

In connection with its adoption of ASC Topic 842, the Company recognized a right of use asset and corresponding operating lease liability of $0.3 million related to this lease as of January 1, 2019. The Company elected to use the package of practical expedients in implementing ASC Topic 842 under which the Company did not reassess the operating or finance lease classification of its previously existing leases. Further, the Company did not reassess whether expired or existing contracts include leases. In August 2019, the Company leased new office space for its headquarters location under an operating lease.

The Exchange Agreement requires the surrender of an equal number of vTv Units and Class B Common Stock for (i) shares of Class A Common Stock on a one-for-one basis or (ii) cash (based on the fair market value of the Class A Common Stock as determined pursuant to the Exchange Agreement), at the Company’s option (as the managing member of vTv LLC), subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications. The exchange value is determined based on a 20-day volume weighted average price of the Class A Common Stock as defined in the Exchange Agreement, subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications. The redeemable noncontrolling interest is recognized at the higher of (1) its initial fair value plus accumulated earnings/losses associated with the noncontrolling interest or (2) the redemption value as of the balance sheet date. At June 30, 2020 and December 31, 2019, the redeemable noncontrolling interest was recorded based on the redemption value as of the balance sheet date of $63.4 million and $40.2 million, respectively.

Related Party Transactions [Abstract]
Related-Party Transactions	Note 10: Related-Party Transactions MacAndrews & Forbes Incorporated As of June 30, 2020, subsidiaries and affiliates of MacAndrews & Forbes Incorporated (collectively “MacAndrews”) indirectly controlled 23,084,267 shares of the Company’s Class B Common Stock and 34,731,212 shares of the Company’s Class A Common Stock. As a result, MacAndrews’ holdings represent approximately 81.4% of the combined voting power of the Company’s outstanding common stock. The Company has entered into several agreements with MacAndrews or its affiliates as further detailed below: Letter Agreements The Company has entered into the Letter Agreements with MacAndrews. Under the terms of the Letter Agreements, the Company has the right to sell to MacAndrews shares of its Class A Common Stock at a specified price per share , and MacAndrews has the right (exercisable up to three times) to require the Company to sell to it shares of Class A Common Stock at the same price. Certain terms of these Letter Agreements are set forth in the table below: December 11, 2018 Letter Agreement March 18, 2019 Letter Agreement September 26, 2019 Letter Agreement December 23, 2019 Letter Agreement Aggregate dollar value to be sold under agreement $10.0 million $9.0 million $10.0 million $10.0 million Specified purchase price per share $ 1.84 $ 1.65 $ 1.46 $ 1.60 Expiration date of letter agreement December 11, 2019 March 18, 2020 September 26, 2020 December 23, 2020 Shares available to be issued under related warrants 340,534 — 400,990 365,472 Exercise price of related warrants $ 2.12 $ — $ 1.68 $ 1.84 Expiration date of related warrants December 11, 2025 September 26, 2026 December 23, 2026 Total shares issued as of June 30, 2020 5,434,783 5,454,546 6,849,316 4,375,000 Remaining shares to be issued as of June 30, 2020 — — — 1,875,000 The March 18, 2019 Letter Agreement resulted in a deemed distribution to MacAndrews of $3.7 million. This deemed distribution was the result of the fair value of the financial instruments issued to MacAndrews exceeding the fair value of the financial instrument received by the Company. This deemed distribution has been reflected as an increase to the net loss attributable to common shareholders of vTv Therapeutics Inc. for computing net loss per share. The Letter Agreement Warrants have been recorded as warrant liability, related party within the Company’s Condensed Consolidated Balance Sheets based on their fair value. The issuance of the Letter Agreement Warrants was considered to be a cost of equity recorded as a reduction to additional paid-in capital. Exchange Agreement The Company and MacAndrews are party to an exchange agreement (the “Exchange Agreement”) pursuant to which the vTv Units (along with a corresponding number of shares of the Class B Common Stock) are exchangeable for (i) shares of the Company’s Class A Common Stock on a one-for-one basis or (ii) cash (based on the fair market value of the Class A Common Stock as determined pursuant to the Exchange Agreement), at the Company’s option (as the managing member of vTv LLC), subject to customary conversion rate adjustments for stock splits, stock dividends and reclassifications. Any decision to require an exchange for cash rather than shares of Class A Common Stock will ultimately be determined by the entire board of directors of vTv Therapeutics Inc. (the “Board of Directors”). As of June 30, 2020, MacAndrews had not exchanged any shares under the provisions of the Exchange Agreement. Tax Receivable Agreement The Company and MacAndrews are party to a tax receivable agreement (the “Tax Receivable Agreement”), which provides for the payment by the Company to M&F TTP Holdings Two LLC (“M&F”), as successor in interest to vTv Therapeutics Holdings, LLC (“vTv Therapeutics Holdings”), and M&F TTP Holdings LLC (or certain of its transferees or other assignees) of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes (or, in some circumstances, the Company is deemed to realize) as a result of (a) the exchange of Class B Common Stock, together with the corresponding number of vTv Units, for shares of the Company’s Class A Common Stock (or for cash), (b) tax benefits related to imputed interest deemed to be paid by the Company as a result of the Tax Receivable Agreement and (c) certain tax benefits attributable to payments under the Tax Receivable Agreement. As no shares have been exchanged by MacAndrews pursuant to the Exchange Agreement (discussed above), the Company has not recognized any liability nor has it made any payments pursuant to the Tax Receivable Agreement as of June 30, 2020. Investor Rights Agreement The Company is party to an investor rights agreement with M&F, as successor in interest to vTv Therapeutics Holdings (the “Investor Rights Agreement”). The Investor Rights Agreement provides M&F with certain demand, shelf and piggyback registration rights with respect to its shares of Class A Common Stock and also provides M&F with certain governance rights, depending on the size of its holdings of Class A Common Stock. Under the Investor Rights Agreement, M&F was initially entitled to nominate a majority of the members of the Board of Directors and designate the members of the committees of the Board of Directors.

Income Tax Disclosure [Abstract]
Income Taxes	Note 11: Income Taxes The Company is subject to U.S. federal income taxes as well as state taxes. The Company did not record an income tax provision for the three and six months ended June 30, 2020. The Company recorded an income tax provision of $0.1 million for the three and six months ended June 30, 2019 related to the foreign withholding taxes paid in connection with payments recognized under the Newsoara License Agreement. Management has evaluated the positive and negative evidence surrounding the realization of its deferred tax assets, including the Company’s history of losses, and under the applicable accounting standards determined that it is more-likely-than-not that the deferred tax assets will not be realized. The difference between the effective tax rate of the Company and the U.S. statutory tax rate of 21% at June 30, 2020 is due to the valuation allowance against the Company’s expected net operating losses. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 outbreak / pandemic. The CARES Act made various tax law changes including among other things (i) increased the limitation under IRC Section 163(j) for 2019 and 2020 to permit additional expensing of interest (ii) enacted a technical correction so that qualified improvement property can be immediately expensed under IRC Section 168(k) and (iii) made modifications to the federal net operating loss rules including permitting federal net operating losses incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years in order to generate a refund of previously paid income taxes. The Company is currently evaluating the impact of the CARES Act but does not expect it to have a material impact on its financial statements as the Company has historically generated federal net operating losses and maintains a full valuation allowance against its deferred tax assets. As discussed in Note 10, the Company is party to a tax receivable agreement with a related party which provides for the payment by the Company to M&F (or certain of its transferees or other assignees) of 85% of the amount of cash savings, if any, in U.S. federal, state and local income tax or franchise tax that the Company actually realizes (or, in some circumstances, the Company is deemed to realize) as a result of certain transactions. As no transactions have occurred which would trigger a liability under this agreement, the Company has not recognized any liability related to this agreement as of June 30, 2020.

Earnings Per Share [Abstract]
Net Loss per Share	Note 12: Net Loss per Share Basic loss per share is computed by dividing net loss attributable to vTv Therapeutics Inc. by the weighted-average number of shares of Class A Common Stock outstanding during the period. Diluted loss per share is computed giving effect to all potentially dilutive shares. Diluted loss per share for all periods presented is the same as basic loss per share as the inclusion of potentially issuable shares would be antidilutive. A reconciliation of the numerator and denominator used in the calculation of basic and diluted net loss per share of Class A Common Stock is as follows (in thousands, except share and per share amounts): For the Three Months Ended June 30, For the Six Months Ended June 30, 2020 2019 2020 2019 Numerator: Net loss $ (4,991 ) $ (5,114 ) $ (12,156 ) $ (9,096 ) Less: Net loss attributable to noncontrolling interests (1,623 ) (2,232 ) (4,064 ) (4,059 ) Net loss attributable to vTv Therapeutics Inc.

Restructuring	Note 13: Restructuring In December 2018, the Company initiated a corporate restructuring to align with a strategic decision to continue the development of its drug candidates using external resources rather than internal resources. The restructuring allowed the Company to reduce costs while continuing to conduct clinical trials, to support existing partnerships that are advancing development of additional assets, and to pursue new licensing and partnership opportunities. This restructuring included a significant reduction in its workforce. The Company completed these restructuring activities in the second quarter of 2019. During the six months ended June 30, 2019, the Company made cash payments of $0.3 million related to these severance benefits and recognized an immaterial amount of expense related to this plan. No such amounts were paid nor was any expense recognized related to restructuring activities during the three or six months ended June 30, 2020.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Note 14: Fair Value of Financial Instruments The carrying amount of certain of the Company’s financial instruments, including cash and cash equivalents, net accounts receivable, accounts payable and other accrued liabilities approximate fair value due to their short-term nature. The fair value of the Company’s Loan Agreement is considered to approximate its carrying value because it bears interest at a variable interest rate. The Company measures the value of its investment in Reneo at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or similar investment. During the three and six months ended June 30, 2020, there were no observable price changes in identical or similar investments, nor were there any indications of impairment. As such, the value of the Company’s investment in Reneo was not remeasured. Assets and Liabilities Measured at Fair Value on a Recurring Basis The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period. This determination requires significant judgments. The following table summarizes the conclusions reached regarding fair value measurements as of June 30, 2020 and December 31, 2019 (in thousands): Balance at June 30, 2020 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Warrant liability, related party (1) $ 3,529 $ — $ — $ 3,529 Total $ 3,529 $ — $ — $ 3,529 Balance at December 31, 2019 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Warrant liability, related party (1) $ 2,601 $ — $ — $ 2,601 Total $ 2,601 $ — $ — $ 2,601 (1) Fair value determined using the Black-Scholes option pricing model. Expected volatility is based on a portfolio of selected stocks of companies believed to have market and economic characteristics similar to its own. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of the valuation. Changes in Level 3 instruments for the six months ended June 30, Balance at January 1 Net Change in fair value included in earnings Purchases / Issuance Sales / Repurchases Balance at June 30, 2020 Warrant liability, related party $ 2,601 $ 928 $ — $ — $ 3,529 Total $ 2,601 $ 928 $ — $ — $ 3,529 2019 Warrant liability, related party $ 2,436 $ (1,196 ) $ — $ — $ 1,240 Total $ 2,436 $ (1,196 ) $ — $ — $ 1,240 During the three and six months ended June 30, 2020 and 2019, the Company recognized a loss of $0.6 million and a gain of $0.3 million, respectively, for the three month periods and a loss of $0.9 million and a gain of $1.2 million, respectively, for the six month periods related to the change in fair value of the Letter Agreement Warrants. These amounts were recognized as a component of other (expense) income – related party in the Condensed Consolidated Statements of Operations. Significant inputs utilized in the valuation of the Letter Agreement Warrants as of June 30, 2020 and December 31, 2019 were: June 30, 2020 December 31, 2019 Expected volatility 116.25% - 132.55% 110.76% - 123.83% Risk-free interest rate 0.26% - 0.44% 1.69% - 1.83% Changes in the unobservable inputs noted above would impact the amount of the liability for the Letter Agreement Warrants. Increases (decreases) in the estimates of the Company’s annual volatility would increase (decrease) the liability and an increase (decrease) in the annual risk-free rate would increase (decrease) the liability.

Subsequent Events [Abstract]
Subsequent Events	Note 15: Subsequent Events On July 29, 2020, the Company entered into the Third Amendment to the Loan Agreement . The Third Amendment allows for interest-only payments for the amounts due on July 1, 2020 and August 1, 2020. The Third Amendment also provides for a one-month extension in the maturity date of the first tranche to September 1, 2020, on which date the remaining outstanding principal balance and associated final payment will be due. Further, the Third Amendment amends the payment schedule for the second tranche, requiring equal monthly principal payments plus accrued interest beginning September 1, 2020 through the scheduled maturity on January 1, 2021. Finally, the Third Amendment removes the requirement for the Company to maintain a minimum cash balance for the remainder of the loan term. As consideration for these amendments, the final payment for the second tranche, due upon maturity, has been increased by approximately $0.1 million.

Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying Condensed Consolidated Balance Sheet as of June 30, 2020, Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2020 and 2019, Condensed Consolidated Statement of Changes in Redeemable Noncontrolling Interest and Stockholders’ Deficit for the three and six months ended June 30, 2020 and 2019 and Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2020 and 2019 are unaudited. These unaudited financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These financial statements should be read in conjunction with the audited financial statements and the accompanying notes for the year ended December 31, 2019 contained in the Company’s Annual Report on Form 10-K. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of June 30, 2020, the results of operations for the three and six months ended June 30, 2020 and 2019 and cash flows for the six months ended June 30, 2020 and 2019. The December 31, 2019 Condensed Consolidated Balance Sheet included herein was derived from the audited financial statements but does not include all disclosures or notes required by GAAP for complete financial statements. The financial data and other information disclosed in these notes to the financial statements related to the three and six months ended June 30, 2020 and 2019 are unaudited. Interim results are not necessarily indicative of results for an entire year. The Company does not have any components of other comprehensive income recorded within its Condensed Consolidated Financial Statements, and, therefore, does not separately present a statement of comprehensive income in its Condensed Consolidated Financial Statements.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to the grant date fair value of equity awards, the fair value of warrants to purchase shares of its Class A Common Stock, the fair value of the Class B Common Stock, the useful lives of property and equipment, the fair value of derivative liabilities, and the fair value of the Company’s debt, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable, the results of which form the basis for making judgments about the carrying value of assets and liabilities.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially expose the Company to concentrations of credit risk consist principally of cash on deposit with multiple financial institutions. The balances of these cash accounts frequently exceed insured limits. Three customers represented 100% of the revenue earned during the three and six months ended June 30, 2019. Revenue for the three and six months ended June 30, 2020 was insignificant.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers any highly liquid investments with an original maturity of three months or less to be cash and cash equivalents.
Restricted Cash and Cash Equivalents	Restricted Cash and Cash Equivalents Restricted cash and cash equivalents as of December 31, 2019 was $2.5 million. This amount relates to the minimum balance that the Company was required to maintain in a deposit account that was pledged to secure the Loan Agreement and was subject to an account control agreement pursuant to the Loan Agreement. There was no restricted cash and cash equivalents as of June 30, 2020, as the Loan Agreement was amended to remove the minimum cash balance requirements (See Note 5 for further details). The following table provides a reconciliation of cash, cash equivalents and restricted cash and cash equivalents reported within the Condensed Consolidated Balance Sheets as of June 30, 2020 and December 31, 2019 that sum to the total of the same such amounts shown in the Condensed Consolidated Statements of Cash Flows (in thousands): June 30, 2020 December 31, 2019 Cash and cash equivalents $ 6,392 $ 1,777 Restricted cash and cash equivalents — — Restricted cash and cash equivalents, long-term — 2,500 Total cash, cash equivalents and restricted cash and cash equivalents shown in the consolidated statement of cash flows $ 6,392 $ 4,277
Investments	Investments In connection with the license agreement with Reneo Pharmaceuticals, Inc. (“Reneo”) (the “Reneo License Agreement”) common stock representing a minority equity interest in Reneo No adjustments were made to the value of the Company’s investment in Reneo for the three and six months ended June 30, 2020 and 2019 either due to impairment or based on observable price changes.
Revenue Recognition	Revenue Recognition The Company uses the revenue recognition guidance established by ASC Topic 606, “Revenue From Contracts With Customers” (“ASC Topic 606”). The majority of the Company’s revenue results from its license and collaboration agreements associated with the development of investigational drug products. The Company accounts for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The transaction price under the contract is determined based on the value of the consideration expected to be received in exchange for the transferred assets or services. Development, regulatory and sales milestones included in the Company’s collaboration agreements are considered to be variable consideration. The amount of variable consideration expected to be received is included in the transaction price when it becomes probable that the milestone will be met. For contracts with multiple performance obligations, the contract’s transaction price is allocated to each performance obligation using the Company’s best estimate of the standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling price is the expected cost plus margin approach. Revenue is recognized over the related period over which the Company expects the services to be provided using a proportional performance model or a straight-line method of recognition if there is no discernable pattern over which the services will be provided.
Research and Development	Research and Development Major components of research and development costs include cash and share-based compensation, costs of preclinical studies, clinical trials and related clinical manufacturing, costs of drug development, costs of materials and supplies, regulatory and compliance costs, fees paid to consultants and other entities that conduct certain research and development activities on the Company’s behalf, facilities costs, and overhead costs. Research and development costs are expensed as incurred. The Company records accruals based on estimates of the services received, efforts expended, and amounts owed pursuant to contracts with numerous contract research organizations. In the normal course of business, the Company contracts with third parties to perform various clinical study activities in the ongoing development of potential products. The financial terms of these agreements are subject to negotiation and variation from contract to contract and may result in uneven payment flows. Payments under the contracts depend on factors such as the achievement of certain events and the completion of portions of the clinical study or similar conditions. The objective of the Company’s accrual policy is to match the recording of expenses in its financial statements to the actual services received and efforts expended. As such, expense accruals related to clinical studies are recognized based on the Company’s estimate of the degree of completion of the event or events specified in the specific clinical study. The Company records nonrefundable advance payments it makes for future research and development activities as prepaid expenses. Prepaid expenses are recognized as expense in the Condensed Consolidated Statements of Operations as the Company receives the related goods or services. Research and development costs that are reimbursed under a cost-sharing arrangement are reflected as a reduction of research and development expense.
