The Department of Defense (DOD) is seeking innovative solutions for Host Directed Therapeutics (HDTs) aimed at treating viral diseases, as part of its Small Business Innovation Research (SBIR) program. The objective is to develop and demonstrate the efficacy of broadly active HDTs that can serve as treatments or prophylactic measures against infections from various viral families, including Filoviruses, Togaviruses, and Hantaviruses. This initiative addresses significant gaps in treatment options for serious viral infections, with the potential for applications in both civilian and military populations. The solicitation is currently closed, with the next opportunity opening on August 22, 2024, and applications due by September 24, 2024.
