Collaborative Arrangement [Abstract]
California Institute of Regenerative Medicine Award	California Institute of Regenerative Medicine Award On September 18, 2015, the Company received an award in the amount of $19.9 million from the California Institute of Regenerative Medicine (CIRM) to partially fund the Company’s Phase 3 trial of ICT-107. The award originally provided for a $4.0 million project initial payment that was received during the fourth quarter of 2015, and up to $15.9 million in future milestone payments that were primarily dependent on patient randomization in the ICT-107 Phase 3 trial. In August 2016, the Company and CIRM modified the award such that the Company received an additional $1.5 million initial payment. The total amount of the award and other award conditions remained unchanged. Under the terms of the CIRM award, the Company was obligated to share future ICT-107 related revenue with CIRM. The percentage of revenue sharing was dependent on the amount of the award received by the Company and whether the revenue is from product sales or license fees. The maximum revenue sharing amount the Company may have been required to pay to CIRM is equal to nine (9) times the total amount awarded and paid to the Company. The Company had the option to decline any and all amounts awarded by CIRM. As an alternative to revenue sharing, the Company had the option to convert the award to a loan, which such option the Company must exercise on or before ten (10) business days after the FDA notifies the Company that it has accepted the Company’s application for marketing authorization. In the event the Company exercised its right to convert the award to a loan, it would have been obligated to repay the loan within ten (10) business days of making such election, including interest at the rate of the three-month LIBOR rate plus 25% per annum. Since the Company may have been required to repay some or all of the amounts awarded by CIRM, the Company accounted for this award as a liability rather than revenue and accrued interest through June 20, 2017, at the aforementioned rates. As described in Note 1, the Company suspended the Phase 3 trial of ICT-107 and will not be required to return the CIRM funds that were spent on the trial. Consequently, during the year ended December 31, 2017, the Company recognized a gain of $7,719,440 as derecognition of the CIRM award liability including accrued interest. No amounts are owed to CIRM as of March 31, 2018.
