How many Challenge Grants will the NHLBI fund?
A3. TBD. The OD will allocate approximately $200 M to fund Challenge Grants. The number of additional Challenge Grants to be supported by the NHLBI with ARRA funds will depend upon the quality of the applications received. Scientific merit will remain the primary funding consideration, but consideration will also be given to NHLBI program priorities, the likelihood that the proposed research can be completed within 2 years, the extent to which a project meets the requirements of the ARRA, and relevant demographic considerations.
