The Department of Defense, through the United States Army Medical Research Acquisitions Activity (USAMRAA), intends to modify an existing contract related to the CryoPreserved Platelets (CPP) project. This modification aims to increase the cost ceiling to accommodate the need for additional subjects in clinical trials, which is critical for advancing to Phase 3 and obtaining FDA licensure for CPP. The contract modification will cover various activities, including the recruitment of up to 400 more subjects, increased consultant and travel expenses, material costs, regulatory expenses, and site activations, with no other FDA-licensed manufacturers for CPP identified in the U.S. Interested suppliers are encouraged to respond in writing within 15 days of this notice, and inquiries can be directed to Peter Mitchell at peter.d.mitchell8.civ@health.mil.
