Insmed Reports Positive Topline Landmark ASPEN Study Results

DENVER, Colo., May 28, 2024 ( Insmed Incorporated (Nasdaq: INSM) reported positive topline results from the Phase 3 ASPEN study, which met its primary endpoint and several of its prespecified secondary endpoints with statistical significance.

“I am thrilled that the ASPEN study has demonstrated a statistically significant and clinically meaningful treatment effect for brensocatib compared with placebo, underscoring the impact this investigational therapy may have on patients with bronchiectasis,” commented lead study investigator James Chalmers, MBChB, Ph.D., Professor and Consultant Respiratory Physician at the School of Medicine, University of Dundee, UK. “Today, there is no approved treatment for bronchiectasis and there remains an urgent need for a therapy that can reduce exacerbations. As a DPP1 inhibitor, brensocatib would be the first treatment in its class and could offer a completely new approach to managing this difficult-to-treat patient population, heralding a new era in clinical management of bronchiectasis.”

“We are incredibly excited about the topline results from the pivotal ASPEN study and what they may mean for patients. These findings not only underscore our belief that brensocatib has the potential to transform the treatment landscape for bronchiectasis, but they also further validate DPP1 inhibition as a mechanism that may hold promise in other neutrophil-mediated diseases,” stated Insmed’s Chief Medical Officer, Martina Flammer, M.D., MBA. “Today’s outcome is the result of years of hard work and dedication by many members of the Insmed team, and I’d like to thank them for their efforts. We are especially grateful to the clinical investigators, site staff, patients, and families who made this study possible. We now look forward to further analyzing the data while rapidly advancing toward regulatory filings in our key regions, where we believe approximately 1 million bronchiectasis patients may benefit from an approved treatment.”
