NIGMS accepts investigator-initiated applications for clinical trials using the R01 mechanism with the following considerations and limitations (see NOT-GM-22-027 for further details).
Clinical studies that do not meet the Revised NIH Definition of “Clinical Trial” should be submitted via the PA 20-185 NIH Research Project Grant (Parent R01 Clinical Trial Not Allowed) notice of funding opportunity. NIGMS encourages discovery research in the NIGMS clinical research areas – for example, an observational study intended to provide biospecimens for molecular analyses that provide mechanistic understanding that will inform future clinical research/trials. We strongly encourage advance discussion with NIGMS staff of all applications that involve clinical studies or clinical trials. All clinical study and clinical trial applications above $500,000 direct costs in any one year are subject to NIH pre-submission requirements.
