The NIAID Investigator-Initiated Clinical Trials program from the National Institute of Allergy and Infectious Diseases provides funding for clinical research on infectious diseases, allergic diseases, and immunological conditions.

NIAID supports a wide range of clinical trial designs, from early-phase feasibility studies to large pivotal trials, enabling investigators to test novel treatments, vaccines, diagnostics, and prevention strategies. Eligible applicants include nonprofits, for-profit organizations, and other entities conducting biomedical research in areas aligned with NIAID's mission.

Award amounts vary by the scope and phase of the proposed clinical trial.

gov and nih. gov for the most up-to-date information on NIH research. If you haven’t done so already, check NIAID’s Clinical Trial Research page and confirm whether your planned research meets NIH’s definition of a clinical trial.

Then read this page for NIAID’s unique requirements for investigator-initiated clinical trials (IICTs). Follow the NIAID IICT Process What To Do If You Need an Extension After Award IICT Resources for Staff and Applicants Follow the NIAID IICT Process To apply for your own clinical trial outside of NIAID’s Networks , you must follow NIAID’s rules and process for IICTs as described below. Otherwise, we will not accept your application.

Start with NIAID’s Investigator-Initiated Clinical Trial Planning and Implementation Awards SOP , then read the following: Investigator-Initiated Clinical Trials Questions and Answers Four Tips for Investigator-Initiated Clinical Trial Applications Decide which notice of funding opportunity (NOFO) best suits your research: NIH Research Project Grant (Parent R01, Clinical Trial Required) —best for clinical trials that are not high-risk* NIH Exploratory/Developmental Research Grant Program (Parent R21, Clinical Trial Required) —best for mechanistic or investigative studies that are not high-risk* NIAID Clinical Trial Implementation Cooperative Agreement (U01, Clinical Trial Required) —best for clinical trials that are high-risk* NIAID SBIR Phase II Clinical Trial Implementation Cooperative Agreement (U44, Clinical Trial Required) —the only choice for small businesses *For the NIAID definition of high risk, check How do I determine my level of risk?

on IICT Awards – General Questions and Answers . At least 10 weeks before your application’s due date (12 weeks for applications that request more than $1 million a year in direct costs), speak to the scientific/research contact listed in the NOFO to request a prior consultation.

The purpose of this consultation is four-fold: Assure you that your proposed clinical trial meets NIAID’s goals, fits within our mission, and addresses a high-priority research area. Determine the risk level of your proposed trial. Review the information and documents you’ll need to include in your application.

Identify other mechanisms to support your clinical trial, e.g., through a different notice of funding opportunity or one of our clinical trial networks. Prepare for that discussion using our guide, Requesting Prior Consultation—Clinical Trial Applications and Planning Grants . Last, write your application and gather all documentation you’ll need when you apply.
