Funding Mechanisms for NIH SBIR and STTR

Discovery and Development

Phase I – feasibility, up to $256 K total costs for 6-12 months.

Phase II- Full research and development, up to $1.7 M total costs for 2 years.

Fast Track Application – simultaneous submission and review of Phase I and Phase II.  If funded, the phase I is awarded, the milestone/aims of phase I are assessed by the program staff before the phase II is awarded.

Direct to Phase II – This is for SBIR grants only, it bypasses the Phase I grant. Must have completed Phase I type research and development (feasibility study) to move directly to phase II. Not all ICs participate. NIBIB does participate.

Competing Renewal Award

Phase IIB – competing renewal award up to $3M for up to 3 years, NIBIB does not participate.


Phase III- commercialization, NIH is not usually the end customer.
