This Funding Opportunity Announcement (FOA) solicits Small Business Innovation Research (SBIR) applications from small business concerns (SBCs) that seek additional funding to support the next stage of development for projects that were previously funded under SBIR or STTR Phase II awards from any Federal agency. Projects proposed in response to this FOA must be applicable to one of the following areas: (1) cancer therapeutics; (2) cancer imaging technologies, interventional devices, and in vivo diagnostics; or (3) in vitro and ex vivo cancer diagnostics and prognostics. The purpose of this FOA is to facilitate the transition of SBIR or STTR Phase II projects to the commercialization stage. This FOA is expected to promote partnerships between Federally-funded SBIR or STTR Phase II awardees and third-party investors and/or strategic partners to facilitate and accelerate the capital-intensive steps that are required to commercialize new products and services. Consistent with the goals of this funding initiative and as required by the SF424 instructions for all Phase II SBIR applications, applicants must submit a Commercialization Plan, which should include details on any independent third-party investor funding that has already been secured or is anticipated during the Phase IIB Bridge Award project period. It is expected that the level of this independent third-party funding will be equal to or greater than the NCI funds being requested throughout the Phase IIB Bridge Award project period. Proposed projects may address preclinical and/or clinical stages of technology development. Clinical trials may be proposed as appropriate but are not required.
