The Food and Drug Administration (FDA) is announcing the availability of grant funds for the support of FDA’s Office of Orphan Products Development grant program. The goal of FDA’s Orphan Products Development (OPD) grant program is to support the clinical development of products for use in rare diseases or conditions where no current therapy exists or where the proposed product will be superior to the existing therapy. FDA provides grants for clinical studies on safety and/or effectiveness that will either result in, or substantially contribute to, market approval of these products. Applicants must include in the application’s Background and Significance section documentation to support the assertion that the product to be studied meets the statutory criteria to qualify for the grant and an explanation of how the proposed study will either help support product approval or provide essential data needed for product development.
