Quick Summary

The Advanced Research Projects Agency for Health (ARPA-H) has issued an Innovative Solutions Opening (ISO) for the Critical Illness Immunological Reprogramming and Control Point Learning Engine (CIRCLE) program. This initiative seeks to develop a Control Point Validation Engine to improve intensive care unit (ICU) health outcomes, reduce stay times, and lower associated costs by assessing, predicting, and treating immuno-inflammatory dysregulation. Multiple Other Transaction (OT) Agreements are anticipated. This is an open competition, with full proposals due by May 28, 2026.

Purpose & Scope

The CIRCLE program aims to achieve a 25% reduction in average ICU stay by enabling personalized immunotherapy and improved patient outcomes. The program is structured around three Technical Areas (TAs) and three Acceleration Platforms (APs):

  • TA1: Measure – Develop real-time, tissue-specific immuno-inflammation biomarker sensors and diagnostics.
  • TA2: Model – Create personalized computational models (digital twins) to predict critical illness trajectories and identify control points.
  • TA3: Modulate – Develop and test interventions to modulate immune responses to control critical illness.
  • APs – Provide independent verification, validation, data analysis, FDA-compliant modeling platforms, and clinical trial support.

Contract Details

This is a Solicitation for a 5-year, 3-phase program, with awards made via Other Transaction (OT) Agreements. Multiple awards are anticipated. There is no specific set-aside, making it an open competition for universities, non-profit organizations, small businesses, and other than small businesses. Federally Funded Research and Development Centers (FFRDCs) and U.S. Government entities are not permitted to participate as prime or sub-performers. Non-U.S. entities may participate if compliant with regulations.

Submission & Evaluation

Proposers must submit a Solution Summary prior to a full proposal.

  • Proposers' Day: March 11, 2026
