The Department of Health and Human Services, specifically the National Institutes of Health (NIH), is issuing a Notice of Intent to Sole Source for a modification to extend the ordering period of Indefinite Delivery, Indefinite Quantity (IDIQ) Contract 75N94019D00004 with Health Decisions, Inc. (HDI) for an additional 27 months. This extension is critical to ensure the continuity of statistical and clinical coordinating support for the Contraceptive Development Program (CDP) and ongoing clinical trials of contraceptive products, which include essential tasks such as protocol development, regulatory compliance, and data analysis. The incumbent contractor, HDI, possesses unique qualifications necessary for these activities, and transitioning to a new contractor at this stage could jeopardize data integrity and patient safety. Interested parties may submit a capabilities statement by May 21, 2025, to demonstrate their ability to meet the government's requirements; however, no solicitation or competitive proposals will be requested.
