The National Bleeding Disorders Foundation (NBDF) is interested in helping hematology investigators continue their critical research into inherited bleeding disorders amidst severe funding reductions for the National Institutes of Health (NIH). To assist with funding research, one-year awards of $125,000 will be granted to hematology investigators focused on inherited bleeding disorders who applied for an NIH R01 grant or equivalent federal grant but were denied funding. NBDF Bridge Grants are intended to help sustain recipients' research and contribute to their retention in bleeding disorders investigation.

Funding Amount: $125,000 for one year.

Supported Research

Proposals to conduct research in the hematology sub-specialty of inherited bleeding disorders. Proposals that fall within the categories of basic, translational, patient-oriented, and outcomes-based research are welcome as long as they relate to inherited bleeding disorders and fulfill the other eligibility criteria. Specific definitions of the above research are available upon request.

Eligibility Requirements

The NBDF Bridge Grant is open to hematology investigators at various career stages who meet eligibility requirements. MDs/DOs, PhDs, and physician-PhDs conducting bleeding disorders research are encouraged to apply.

To be considered for an NBDF Bridge Grant, the applicant must:

  • Have submitted to the NIH or other federal granting body in the past 18 months an Inherited bleeding disorder-related R01 or R01-equivalent application that was scored but not funded. The applicant must be the Principal Investigator on the submission.
    Please note: The 18-month timeframe begins the date your R01 was reviewed by the NIH study section. NBDF uses the NIH definition of R01 equivalence: “R01-equivalent awards include R01, R23, R29, and R37 activity codes and, beginning in fiscal year 2008, DP2 awards to first-time NIH investigators. Not all activities are in use by NIH every year.”
  • Hold a faculty position at an academic institution, the equivalent position at a non-profit research organization, and/or a federally funded hemophilia treatment center. Employees of independent research institutions are eligible to apply if they have a faculty-type appointment and the institution is allowed to independently apply for and receive NIH funding.
  • Have the commitment of his/her institution to match $50,000 in funds.
  • At the time of award activation, have available no more than $250,000 annually in other research funding including institutional/internal research funding. This amount does not include the applicant's salary/fringe or funding from within the institution.


  • Previous Bridge Grant recipients cannot apply for a second award.
  • Other than a Career Development Award or Fellowship, individuals cannot hold two active NBDF awards concurrently. If the other NBDF award ends before the Bridge Grant begins, you may apply but there can be no overlap.


Announcements for funding opportunities will be made February 1, 2024.
