Receivables [Abstract]
Grant Award	GRANT AWARD NIH Grant Funding The Company has received notices of awards and grant funding from the National Institutes of Health, or the NIH to support the development of Ovaprene and DARE-FRT1. The NIH issues notices of awards to the Company for a specified amount, and the Company must incur and track expenses eligible for reimbursement under the award and submit a detailed accounting of such expenses to receive payment. If the Company receives payments under the award, the amounts of such payments are recognized in the statement of operations as a reduction to research and development activities as the related costs are incurred to meet those obligations over the period. Ovaprene Since 2018, the Company has received approximately $1.9 million of grant funding from the Eunice Kennedy Shriver National Institute of Child Health and Human Development, a division of the NIH, for clinical development efforts supporting Ovaprene. The most recent and final notice of award the Company received was for approximately $731,000 in April 2020, substantially all of which has been funded to date. The Company recorded credits to research and development expense for costs related to the NIH award of approximately $124,000 and $302,000 for the three months ended September 30, 2020 and September 30, 2019, respectively, and $583,000 and $920,000 for the nine months ended September 30, 2020 and September 30, 2019, respectively. At September 30, 2020, the Company recorded a receivable of approximately $69,000 for expenses incurred through such date that it believes are eligible for reimbursement under the final notice of award received in April 2020. DARE-FRT1 In August 2020, the Company received a notice of award of a grant from the NIH to support the development of DARE-FRT1. The award in the amount of $300,000 was for what is referred to as the "Phase I" segment of the project outlined in the Company's grant application, which is to occur during the period of August 2020 through July 2021. Additional potential funding of up to approximately $2.0 million for the "Phase II" segment of the project outlined in the grant application is contingent upon satisfying specified requirements, including, assessment of the results of the Phase I segment, determination that the Phase I goals were achieved, and availability of funds. There is no guarantee the Company will receive any Phase II award. The Company recorded credits to research and development expense for costs related to the NIH award of approximately $3,000 during the three months ended September 30, 2020. At September 30, 2020, the Company recorded a receivable of approximately $3,000 for expenses incurred through such date that it believes are eligible for reimbursement under the grant. Bill & Melinda Gates Foundation The Company's wholly-owned subsidiary, Microchips, has a grant agreement with the Bill & Melinda Gates Foundation, or the Foundation, relating to the development of the pre-clinical stage contraceptive candidate, DARE-LARC1. Expenses eligible for grant funding must be incurred, tracked and reported to the Foundation. Microchips received grant funding payments of approximately $2.9 million in July 2019, $1.6 million in June 2020 and $899,000 in September 2020. At September 30, 2020, grant funding payments associated with research and development expenses for DARE-LARC1 not yet incurred totaled approximately $2.2 million and are recorded as deferred grant funding liability in the Company's consolidated balance sheet.
