What are the Recent Developments in Global Interstitial Lung Disease Treatment Market?

• In October 2025, the U.S. FDA approved nerandomilast (Jascayd) for treating Idiopathic Pulmonary Fibrosis (IPF), marking the first newly approved IPF therapy in over 10 years. This approval is significant because IPF traditionally has very limited treatment options, with only two major antifibrotics dominating care for more than a decade. Jascayd’s approval followed strong clinical evidence showing reduced lung function decline and a favorable safety profile
• In June 2025, Insilico Medicine announced its intention to start late-stage clinical trials for Rentosertib following its encouraging mid-stage results. The upcoming trials aim to further validate Rentosertib’s potential as a novel treatment for IPF by assessing long-term efficacy and safety across diverse patient populations
• In March 2025, the nonproprietary name Rentosertib was officially assigned to ISM001-055, highlighting the progress of this first-in-class TNIK inhibitor as it moved forward in clinical pipelines. Receiving an official name is a regulatory milestone indicating significant advancement in the drug’s development. Rentosertib also became notable as one of the world’s first small-molecule drugs entirely discovered using generative AI
• In November 2024, Insilico Medicine announced positive topline results from its Phase IIa trial of ISM001-055 (later named Rentosertib) for IPF. The trial demonstrated that the drug was safe, well-tolerated, and showed a dose-dependent improvement in forced vital capacity (FVC) over 12 weeks a key indicator of slowed disease progression
• In September 2024, Boehringer Ingelheim reported that its FIBRONEER-IPF Phase III trial for nerandomilast achieved its primary endpoint, demonstrating a statistically significant difference in FVC decline compared to placebo over 52 weeks. This success strengthened the clinical foundation for subsequent regulatory filings and ultimately contributed to the drug’s approval in 2025
