Bristol Myers Squarb’s lung‑fibrosis drug admilparant meets primary endpoint in Phase 3 IPF trial

Bristol Myers Squibb reported topline data from the Phase 3 ALOFT‑IPF trial of its LPA1 antagonist admilparant. The 60 mg dose achieved a statistically significant improvement in forced vital capacity versus placebo after 52 weeks, while the 120 mg dose did not reach significance. The trial enrolled roughly 1,255 patients and showed a safety profile comparable to placebo. The company said it will engage health authorities for regulatory submissions and present detailed results at a future medical meeting.

The company’s plan to file for regulatory approval could add a new therapy for idiopathic pulmonary fibrosis, a disease with limited treatment options. Mixed market reaction reflects investor uncertainty about the 120 mg result and prior trial revisions.
