Summary: Small grants help current or recently completed NHLBI K01, K08, K23, and K25 awardees generate data and transition to research independence.
Key Information: Applicants must maintain at least 40% protected research effort and cannot have secured an R01 or other substantial NIH independent research award.
Description
The National Heart, Lung, and Blood Institute (NHLBI), part of NIH, runs this limited-competition R03 program for current or recently completed NHLBI K01, K08, K23, and K25 recipients. It supports expansion of current research objectives or new studies emerging from K award research, helping investigators build independent research careers and prepare subsequent R01-equivalent applications.
Projects should be discrete, achievable within two years, and suited to limited resources. Supported work includes pilot and feasibility studies, proof-of-concept studies, secondary analysis of existing data, small self-contained projects, new research methodologies or technologies, and novel experimental model systems. Clinical trials are optional. For current and former K23 recipients, the proposed work need not be patient-oriented research. Preliminary data are not required, particularly for pilot or feasibility studies.
