This 8-K filing officially discloses the initiation of a Phase 1 clinical trial for SEP-479, an oral small molecule designed to treat hypoparathyroidism. This is a crucial pipeline milestone for Septerna, moving a novel candidate from preclinical development into human testing. The advancement is particularly notable given the company's previous discontinuation of another PTH1R agonist (SEP-786) in Phase 1 due to unexpected safety events. The successful initiation of SEP-479 demonstrates the company's ability to learn from prior challenges and advance new candidates in a key therapeutic area, validating its Native Complex Platform®. Data from this trial are anticipated in late 2026 or early 2027.
