Syndax halts axatilimab IPF plans after MAXPIRe misses FVC decline endpoint October 13, 2026

Syndax said its MAXPIRe Phase 2 trial of axatilimab in idiopathic pulmonary fibrosis did not meet the primary endpoint measuring annualized FVC decline, and the company does not plan further IPF development. The company emphasized axatilimab was well tolerated with no new safety signals and said the results do not affect ongoing cGVHD trials, with additional readouts expected later this year and in early 2028.
