Syndax Stock Falls 16% as Phase II Fibrosis Study Misses Primary Goal
Syndax Pharmaceuticals (SNDX) shares fell 15.7% after its phase II MAXPIRe study of axatilimab failed to meet the primary endpoint in idiopathic pulmonary fibrosis (IPF) treatment. The drug showed no benefit in slowing FVC decline, though it maintained a favorable safety profile. The company is discontinuing IPF development but will continue pursuing axatilimab in chronic graft-versus-host disease (cGVHD) with results expected in 2026 and 2028.
