The Department of Health and Human Services, specifically the National Institutes of Health (NIH), has released a solicitation notice for Small Business Technology Transfer (STTR) grant applications. The purpose of this notice is to invite eligible United States small business concerns to submit STTR Phase I, Phase II, Fast-Track, and Phase IIB grant applications. The SBIR and STTR programs aim to support small businesses in conducting research and development with strong potential for commercialization. The main objective of the SBIR and STTR Phase I is to establish the technical merit and feasibility of the proposed research, while Phase II continues the R&D efforts to advance the technology toward commercialization. The NIH also offers the Fast-Track option, which combines Phase I and Phase II applications to reduce or eliminate the funding gap between phases. Additionally, the Phase IIB option provides additional funding for projects that require considerable financing beyond Phase II. The solicitation notice requires all applications to propose clinical trials. The funding opportunity is open until April 6, 2024.
