Accelerated Development Timeline: The partnership allows Gossamer to initiate a Phase III clinical trial for pulmonary hypertension associated with interstitial lung disease (PHILD) much sooner than previously planned, potentially four to five years earlier [6][11][14] 4. Market Opportunity: PHILD is identified as a significant market opportunity with only one approved therapy in the U.S. and none globally, indicating a high unmet medical need [6][10][15] 5. Regulatory Strategy: Gossamer plans to engage with regulatory authorities to finalize the Phase III study design for PHILD, leveraging Chiesi's experience with global regulatory processes [45][46][56] 6. Clinical Trial Design: The ongoing PROCERA study for PAH is progressing well, with expectations for top-line results in Q4 2025. The study involves 175 patients per arm and focuses on the change in six-minute walk distance as a primary endpoint [17][18][19] 7. Patient Population Characteristics: The PHILD patient population is expected to be more severely impaired than typical PAH patients, which may enhance the observed treatment effects in clinical trials [21][73][74] 8. Safety Profile: Gossamer anticipates a favorable safety profile for saralutinib based on previous studies, which is crucial for its acceptance in the market [75] Additional Important Information 1.
