Abstract

Abstract AI CAR Loop 1.0 is a modular, AI-driven platform designed to accelerate Chimeric Antigen Receptor T-cell (CAR-T) therapy development for solid and hematological malignancies, with all demonstrations conducted through computational validation. The platform integrates five interoperable modules (M1–M5): multi-modal antigen discovery, AlphaFold2-based structural modeling and HADDOCK docking of antigen–scFv complexes, mRNA delivery optimization, in vivo feedback simulation, and reinforcement learning optimization. Leveraging Coscientist’s multi-agent framework (51-day optimization, 40% yield increase [3]), it enables rapid, cost-effective prototyping and supports integration of strategic modules like DrugDomain 2.0, AuroBind, REAP, and SMART. Illustrated with CLDN18.2-positive gastric cancer, in silico analyses with public datasets (TCGA, n=375; TCIA, n=200) demonstrate a 40–50% cost reduction, 80–85% target accuracy (±5%, vs. 60–70% traditional methods), and 18–24-month development cycles. All results are derived from computational simulations, with no wet-lab or clinical testing performed. Cross-validation and uncertainty quantification ensure robust metrics. Future work will pursue in vitro and in vivo validation to translate these computational insights into clinical applications.
