FDA accepts first AI-driven in silico DILI tool into ISTAND review path
FDA CDER accepted the first Letter of Intent into ISTAND for an AI-driven in silico drug development tool: a digital liver model intended to predict drug-induced liver injury in small-molecule candidates. The model is designed to complement other DILI risk evidence before Phase 1 decisions if it successfully completes qualification.
No AI drug-safety tool has gone through ISTAND qualification before this LOI. If the model clears the remaining two steps, its output could stand alongside conventional preclinical data ahead of Phase 1 decisions, the qualification, not the algorithm, is what would make that usable.
Track LOI status through all three DDT qualification steps and document the model's context of use, its reference-drug training set, validation endpoints, and version history now, rather than assembling that record when FDA asks for it during qualification review.
