The National Institute of Neurological Disorders and Stroke (NINDS) and the Office of the Director, National Institutes of Health (OD), intend to promote a new initiative by publishing a Funding Opportunity Announcement (FOA) to solicit applications for the conduct of scientific research utilizing data from expanded access (EA) to investigational drugs or biological products. These applications will target intermediate size populations of patients living with amyotrophic lateral sclerosis (ALS) who are not otherwise eligible for clinical trials for the diagnosis, mitigation, treatment, or cure of ALS ("intermediate EA protocol for ALS"). Providing the investigational drug or biological product under an intermediate EA protocol for ALS must not interfere with the initiation, conduct, or completion of clinical investigations that could support marketing approval, or otherwise compromise the potential development of medical products for the diagnosis, mitigation, treatment, or cure of ALS. Eligible applicants are clinical trial sites that participate in a phase 3 clinical trial supported by a United States (U.S.) small business concern (as defined in section 3(a) of the Small Business Act (15 U.S. C. 623(a)) that is also the U.S. Food and Drug Administration (FDA) designated sponsor of a drug or biological product for ALS that is the subject of an Investigational New Drug Application (IND). This Notice is being provided to allow potential applicants sufficient time to develop meaningful collaborations and responsive projects. The FOA is expected to be published in May 2022 with an expected application due date in June 2022. This FOA will utilize the U01 activity code.
