What's Happening?
Savara Inc., a clinical-stage biopharmaceutical company, has presented new data from its Phase 3 IMPALA-2 clinical trial at the European Respiratory Society Congress 2025. The trial evaluates the efficacy and safety of molgramostim, an inhalation solution for patients with autoimmune pulmonary alveolar proteinosis (aPAP). The study demonstrated that molgramostim improved pulmonary gas transfer and quality of life measures compared to placebo, regardless of disease severity. The trial involved 43 sites across 16 countries, including the U.S., and focused on changes in the diffusing capacity of the lungs for carbon monoxide (DLco%) as the primary endpoint.
Why It's Important?
The findings from the IMPALA-2 trial are significant as they offer a potential new treatment for aPAP, a rare lung disease with limited therapeutic options. The improvement in DLco% and quality of life measures suggests that molgramostim could provide substantial benefits to patients suffering from this condition. This development could impact the biopharmaceutical industry by setting a precedent for the treatment of rare respiratory diseases, potentially leading to further research and investment in similar therapies.
What's Next?
Following the positive results from the IMPALA-2 trial, Savara plans to continue the development of molgramostim, with patients who completed the 48-week double-blind treatment period entering a 96-week open-label period. The company will likely seek regulatory approval based on the trial's outcomes, which could lead to the commercialization of molgramostim as a treatment for aPAP.
