Jascayd OK’d for progressive pulmonary fibrosis

January 2, 2026

On December 19, 2025, FDA expanded the approval of Jascayd (nerandomilast), an oral phosphodiesterase inhibitor, to include treatment of progressive pulmonary fibrosis (PPF) in adults.

Efficacy

Approval was based on data from the phase 3 FIBRONEER-ILD trial (NCT05321082), where the primary endpoint was the absolute change from baseline in forced vital capacity (FVC) in mL at week 52. Jascayd demonstrated a significantly smaller reduction in FVC decline from baseline compared with placebo. The adjusted mean decline in absolute change from baseline in FVC in patients receiving Jascayd 18 mg or 9 mg was -86 mL and -69 mL, respectively, vs. -152 mL in the placebo group. The respective treatment difference compared with the placebo group was 65 mL (95% confidence interval [CI], 30-101) and 83 mL (95% CI, 48-118).

Safety

The most common adverse reactions in patients with PPF treated with Jascayd were generally consistent with those observed in patients with IPF.
