Solicitation / RFP / RFQ

This solicitation from DARPA's Biological Technologies Office (BTO) seeks innovative approaches for the Virtual-Integrated Twin for Autonomous Lifesaving (VITAL) program. The program aims to develop continuously updating digital twin models of the cardiovascular system. These models will combine patient data with biological physics to simulate interventions in real-time and predict their outcomes before they are applied to a patient. The ultimate goal is to shift medical care from reactive to anticipatory intervention, improving outcomes across acute, chronic, and emergent clinical settings.

• Development of High Fidelity (HF) digital twin models representing underlying physical, biochemical, and anatomical dynamics.

• Development of Reduced Order Models (ROMs) suitable for real-time responsiveness and continuous updating, derived from HF models.

• Integration of HF and ROM models into a pipeline for intervention simulation and prediction.

• Continuous validation of models to establish bounds of physiological modeling.

• Focus on either chronic conditions (e.g., heart failure) or acute perturbations (e.g., hemorrhagic shock).

• Anticipated Awards: Multiple awards are anticipated.

• Contract Type: Other Transaction for Prototype agreements.

• Period of Performance: 36 months, divided into two phases (Phase 1: 15 months, Phase 2: 21 months).

• Abstract Submission Deadline: May 20, 2026, 5:00 PM ET.

• Proposer's Day: March 31, 2026.

• Questions Due Date: April 23, 2026, 12:00 PM ET.

• Oral Presentations: By Government invitation, July 23, 2026 (anticipated).

• Evaluation will be based on Technical Approach, Technical Ability, and Budget.

• Open to all responsible sources, including large and small businesses, non-traditional defense contractors, universities, and research institutions.

• Attachments include an Abstract Summary Slide Template, Abstract Instructions and Template, and Oral Presentation Proposal (OPP) Package Guidance.

• Proposers must submit abstracts; successful abstract submissions may lead to an invitation to submit an OPP package and participate in oral presentations.
