Accounting Policies [Abstract]
Basis of Presentation	The accompanying interim unaudited consolidated financial statements of Opexa Therapeutics, Inc. (“Opexa” or the “Company”), have been prepared in accordance with accounting principles generally accepted in the United States of America and the rules of the Securities and Exchange Commission (“SEC”) and should be read in conjunction with the audited financial statements and notes thereto contained in Opexa’s latest Annual Report filed with the SEC on Form 10-K. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of financial position and the results of operations for the interim periods presented have been reflected herein. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. Notes to the consolidated financial statements that would substantially duplicate the disclosure contained in the audited consolidated financial statements for the most recent fiscal year as reported in Form 10-K have been omitted. The accompanying consolidated financial statements include the accounts of Opexa and its wholly owned subsidiary, Opexa Hong Kong Limited (“Opexa Hong Kong”). All intercompany balances and transactions have been eliminated in the consolidation. The accompanying unaudited consolidated financial statements for the six months ended June 30, 2016 have been prepared assuming that the Company will continue as a going concern, meaning the Company will continue in operation for the foreseeable future and will be able to realize assets and discharge liabilities in the ordinary course of operations. As of June 30, 2016, the Company had cash and cash equivalents of $7.8 million. While the Company recognizes revenue related to the $5 million and $3 million payments from Merck received in February 2013 and March 2015 in connection with the Option and License Agreement and the Amendment over the exclusive option period based on the expected completion term of the Company’s ongoing Phase IIb clinical trial (“Abili-T”) of Tcelna® in patients with Secondary Progressive MS (“SPMS”), the Company does not currently generate any commercial revenues resulting in cash receipts, nor does it expect to generate revenues during the remainder of 2016 resulting in cash receipts. The Company’s burn rate during the six months ended June 30, 2016 was approximately $763,000 per month, thereby creating substantial doubt about the Company’s ability to continue as a going concern. Additionally, costs associated with completing the ongoing Abili-T trial may result in an increase in the monthly operating cash burn during the remainder of 2016. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. The Company continues to explore potential opportunities and alternatives to obtain the additional resources that will be necessary to support its ongoing operations through and beyond the next 12 months including raising additional capital through either private or public equity or debt financing as well as using its at-the-market offering program and cutting expenses where possible. However, there can be no assurance that the Company will be able to secure additional funds and that if such funds are available, whether the terms or conditions would be acceptable to the Company.

Accounting Policies [Abstract]
Significant Accounting Polices	Revenue Recognition. On February 4, 2013, Opexa entered into an Option and License Agreement (the “Merck Serono Agreement”) with Ares Trading SA (“Merck Serono”), a wholly owned subsidiary of Merck Serono S.A. Pursuant to the terms, Merck Serono has an option to acquire an exclusive, worldwide (excluding Japan) license of Opexa’s Tcelna program for the treatment of multiple sclerosis (“MS”). The option may be exercised by Merck Serono prior to or upon Opexa’s completion of the Phase IIb Trial. Opexa received an upfront payment of $5 million for granting the option. Opexa recognized revenues from nonrefundable, up-front $5 million option fees related to the Merck Serono Agreement on a straight-line basis over the estimated option exercise period which coincides with the expected completion term of the Abili-T clinical trial in SPMS. If the option is exercised, Merck Serono would pay the Company an upfront license fee of $25 million unless Merck Serono is unable to advance directly into a Phase III clinical trial of Tcelna for SPMS without a further Phase II clinical trial (as determined by Merck Serono), in which event the upfront license fee would be $15 million. After exercising the option, Merck Serono would be solely responsible for funding development, regulatory and commercialization activities for Tcelna in MS, although the Company would retain an option to co-fund certain development in exchange for increased royalty rates. The Company would also retain rights to Tcelna in Japan, certain rights with respect to the manufacture of Tcelna, and rights outside of MS. On March 9, 2015 Opexa entered into a First Amendment of Option and License Agreement with Merck Serono, to amend the Merck Serono Agreement (the “Merck Serono Amendment”). Opexa received $3 million in consideration for the following: (i) Creating a detailed plan for potential Phase III development of Tcelna (the “Pre-Phase III Plan”), including documenting all of the activities necessary for laboratory facilities both in the U.S. and Europe to reach operational readiness by the end of December 2016. The Joint Steering Committee (“JSC”) established pursuant to the Merck Serono Agreement will be responsible for reviewing, approving and ultimately overseeing Opexa’s completion of the Pre-Phase III Plan. In the event the JSC has not approved the Pre-Phase III Plan prior to the end of the period in the Merck Serono Agreement within which Merck Serono may exercise its option, such period will be extended for 60 days following approval of the Pre Phase III Plan by the JSC. (ii) Providing Merck Serono with updates and analysis on a blinded basis, grouped in patient batches according to Opexa’s analysis timetable, on the progress of Opexa’s immune monitoring program being conducted in conjunction with the ongoing Abili-T clinical trial. Opexa evaluated the Merck Serono Amendment and determined that the $3 million payment from Merck Serono has stand-alone value. Opexa’s continuing performance obligations in connection with the $3 million payment include the creation of the Pre-Phase III Plan and delivery of updates and analysis relating to Opexa’s immune monitoring program. As a stand-alone value term in the Merck Serono Amendment, the $3 million payment is determined to be a single unit of accounting, and is recognized as revenue on a straight-line basis over the period equivalent to the expected completion of the Pre-Phase III Plan in December 2016. Opexa includes the unrecognized portion of the $5 million option payment and the $3 million amendment payment as deferred revenue on its consolidated balance sheets. Cash and Cash Equivalents. Opexa primarily maintains cash balances on deposit in accounts at a U.S.-based financial institution. The aggregate cash balance on deposit in these accounts is insured by the Federal Deposit Insurance Corporation up to $250,000. Opexa’s cash balances on deposit in these accounts may, at times, exceed the federally insured limits. Opexa has not experienced any losses in such accounts. As of June 30, 2016, Opexa had approximately $7.0 million in a savings account. For the six months ended June 30, 2016, the savings account recognized an average market yield of 0.06%. Interest income of $2,651 was recognized for the six months ended June 30, 2016 in the consolidated statements of operations. Reclassifications.

Equity [Abstract]
Equity	For the six months ended June 30, 2016, equity related transactions were as follows: On March 14, 2016, Opexa entered into an amendment to the September 1, 2015 Stock Purchase Agreement with the purchasers party thereto, to extend by six months the original dates for the milestones relating to the subsequent tranches. As part of the amendment, the expiration date of the Series N warrants issued pursuant to the Stock Purchase Agreement was also extended from April 9, 2018 to October 9, 2018. The Company determined that there is no accounting impact to the modification of the Series N warrants since these are investor warrants. On May 16, 2016, a total of 103,280 shares of common stock with an aggregate fair value of $219,986 were granted to certain non-employee directors for service on Opexa’s Board of Directors.

Opexa estimates the fair value of stock options using the Black-Scholes option-pricing model and records the compensation expense ratably over the service period. Opexa recognized stock based compensation expense of $342,713 and $472,350 during the six months ended June 30, 2016 and 2015, respectively, for grants made to employees. On May 16, 2016, Opexa’s shareholders approved an amendment and restatement of the 2010 Stock Incentive Plan (the “2010 Plan”) to increase the number of shares of common stock reserved for issuance by an additional 650,000 shares and to reset the number of stock-based awards issuable to a participant in any calendar year. On May 16, 2016, time-based options to purchase an aggregate of 200,000 shares at an exercise price of $2.13 were granted to various officers and employees. These options have a term of ten years and become exercisable over a three-year period, with 25% vesting on the grant date and the remaining 75% vesting in equal increments quarterly thereafter (in arrears) over the ensuing three years, subject to continuous service or termination of employment without cause. The fair value of these options of $384,501 was calculated using the Black-Scholes option pricing model. Variables used in the Black-Scholes option model for these options include (1) discount rate of 1.75% (2) expected term of 5.56 years (3) expected volatility rate of 138.59% and (4) zero expected dividends.

This option vests in full if, on or before December 31, 2016, Merck Serono exercises its option to acquire an exclusive, worldwide (excluding Japan) license to Opexa’s Tcelna program for the treatment of multiple sclerosis under that certain Option and License Agreement between Opexa and Merck Serono dated February 4, 2013.

Accounting Policies [Abstract]
Revenue Recognition	Opexa recognizes revenue in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“FASB ASC”) 605, “Revenue Recognition.” ASC 605 requires that four basic criteria must be met before revenue can be recognized: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services rendered; (3) consideration is fixed or determinable; and (4) collectability is reasonably assured. On February 4, 2013, Opexa entered into an Option and License Agreement (the “Merck Serono Agreement”) with Ares Trading SA (“Merck Serono”), a wholly owned subsidiary of Merck Serono S.A. Pursuant to the terms, Merck Serono has an option to acquire an exclusive, worldwide (excluding Japan) license of Opexa’s Tcelna program for the treatment of multiple sclerosis (“MS”). The option may be exercised by Merck Serono prior to or upon Opexa’s completion of the Phase IIb Trial. Opexa received an upfront payment of $5 million for granting the option. Opexa recognized revenues from nonrefundable, up-front $5 million option fees related to the Merck Serono Agreement on a straight-line basis over the estimated option exercise period which coincides with the expected completion term of the Abili-T clinical trial in SPMS. If the option is exercised, Merck Serono would pay the Company an upfront license fee of $25 million unless Merck Serono is unable to advance directly into a Phase III clinical trial of Tcelna for SPMS without a further Phase II clinical trial (as determined by Merck Serono), in which event the upfront license fee would be $15 million. After exercising the option, Merck Serono would be solely responsible for funding development, regulatory and commercialization activities for Tcelna in MS, although the Company would retain an option to co-fund certain development in exchange for increased royalty rates. The Company would also retain rights to Tcelna in Japan, certain rights with respect to the manufacture of Tcelna, and rights outside of MS. On March 9, 2015 Opexa entered into a First Amendment of Option and License Agreement with Merck Serono, to amend the Merck Serono Agreement (the “Merck Serono Amendment”). Opexa received $3 million in consideration for the following: (i) Creating a detailed plan for potential Phase III development of Tcelna (the “Pre-Phase III Plan”), including documenting all of the activities necessary for laboratory facilities both in the U.S. and Europe to reach operational readiness by the end of December 2016. The Joint Steering Committee (“JSC”) established pursuant to the Merck Serono Agreement will be responsible for reviewing, approving and ultimately overseeing Opexa’s completion of the Pre-Phase III Plan. In the event the JSC has not approved the Pre-Phase III Plan prior to the end of the period in the Merck Serono Agreement within which Merck Serono may exercise its option, such period will be extended for 60 days following approval of the Pre Phase III Plan by the JSC. (ii) Providing Merck Serono with updates and analysis on a blinded basis, grouped in patient batches according to Opexa’s analysis timetable, on the progress of Opexa’s immune monitoring program being conducted in conjunction with the ongoing Abili-T clinical trial. Opexa evaluated the Merck Serono Amendment and determined that the $3 million payment from Merck Serono has stand-alone value. Opexa’s continuing performance obligations in connection with the $3 million payment include the creation of the Pre-Phase III Plan and delivery of updates and analysis relating to Opexa’s immune monitoring program. As a stand-alone value term in the Merck Serono Amendment, the $3 million payment is determined to be a single unit of accounting, and is recognized as revenue on a straight-line basis over the period equivalent to the expected completion of the Pre-Phase III Plan in December 2016. Opexa includes the unrecognized portion of the $5 million option payment and the $3 million amendment payment as deferred revenue on its consolidated balance sheets.
Cash and Cash Equivalents	Opexa considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Investments with maturities in excess of three months but less than one year are classified as short-term investments and are stated at fair market value. Opexa primarily maintains cash balances on deposit in accounts at a U.S.-based financial institution. The aggregate cash balance on deposit in these accounts is insured by the Federal Deposit Insurance Corporation up to $250,000. Opexa’s cash balances on deposit in these accounts may, at times, exceed the federally insured limits. Opexa has not experienced any losses in such accounts. As of June 30, 2016, Opexa had approximately $7.0 million in a savings account. For the six months ended June 30, 2016, the savings account recognized an average market yield of 0.06%. Interest income of $2,651 was recognized for the six months ended June 30, 2016 in the consolidated statements of operations.
Reclassifications	Certain reclassifications of prior year reported amounts have been made for comparative purposes. Opexa does not consider such reclassifications to be material and they had no effect on net income.
