Extremity Platform for On-demand Surgical Implantation and Tissue Integration with Osteochondral Neogenesis

The DPA26BZ01-DV004 project seeks to develop an on-demand regenerative medicine platform for complete finger restoration following trauma, aiming to eliminate traditional joint repair surgeries and enable full functional recovery. This initiative addresses the high incidence of post-traumatic osteoarthritis (PTOA) in military personnel, which significantly impacts readiness and long-term health. The project proposes a revolutionary approach to biological finger regeneration, focusing on developing anatomically precise scaffolds and delivering bioactive proteins and therapeutic factors to promote the growth of bone, cartilage, ligaments, tendons, and blood vessels. The goal is to restore native tissue architecture and function, allowing service members to return to unrestricted duty. The project is soliciting Direct to Phase II (DP2) proposals, requiring strong preliminary data demonstrating feasibility in protein engineering, tendon/ligament scaffold integration, and 3D printing. Phase II objectives include completing animal studies, establishing GMP manufacturing, and preparing for clinical trials. The technology has dual-use applications, offering commercial potential for treating traumatic joint injuries and congenital joint disorders in civilians, and military benefits in restoring combat readiness, reducing healthcare costs, and improving veteran quality of life.
