The first ai-designed drug has entered a phase iii trial
the first ai-designed drug has entered a phase iii trial: insilico’s rentosertib started a 320-patient study for pulmonary fibrosis in august. the molecule came from the company’s generative chemistry engine, not a human hypothesis.
the field’s real test is whether the next one clears the fda.
Context
Verified date: Insilico's release dated Jul 7, 2026 says it initiated a Phase III trial of rentosertib, its TNIK inhibitor for idiopathic pulmonary fibrosis. A later release (Sep 9-10, 2026) says the first patient has been dosed in GENESIS-IPF-3, which it calls the world's first Phase III trial of a generative AI-driven drug. ClinicalTrials.gov lists it as NCT07687459, a randomized, double-blind, placebo-controlled study.
Insilico's HKEX announcement of Sep 10, 2026 says it completed first patient enrollment and dosing.
The Phase III trial of rentosertib for pulmonary fibrosis matches. Insilico announced the start on Jul 7 and the first patient dosing on Sep 9-10, so the post's August start does not match either date. The 320-patient size was not seen in the sources read, so unsupported here, not refuted. in the excerpts read. 'First' is Insilico's own wording about its own trial. 'Whether the next one clears the FDA' is the author's opinion.
