Septerna, Inc. Announces Initiation of Phase 1 Trial for Oral PTH1R Agonist SEP-479 in Hypoparathyroidism Septerna, Inc. announced the dosing of the first participants in its Phase 1 clinical trial of SEP-479, its potent oral small molecule PTH1R agonist being developed for the treatment of patients with hypoparathyroidism. The Phase 1 clinical trial is a single-ascending dose (SAD) and multiple-ascending dose (MAD) clinical trial to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of SEP-479 in healthy adult volunteers. The randomized, placebo-controlled Phase 1 clinical trial is expected to enroll up to 150 healthy adult participants. Dosing is underway in the SAD portion of the clinical trial, which will evaluate the safety and tolerability of SEP-479 at escalating oral doses. The MAD portion of the clinical trial is designed to evaluate the safety and tolerability of once-daily oral dosing of SEP-479 over multiple days of treatment, with secondary and exploratory endpoints including PK and PD, with the latter assessed by changes in endogenous PTH and serum calcium, as well as other biomarkers. Septerna anticipates reporting data from the trial in late 2026 or early 2027. Duyuru • Mar 11

Septerna, Inc. Announces Positive Phase 1 Data for Sep-631, an Oral Mrgprx2 Nam for the Treatment of Mast Cell-Driven Diseases, and Outlines Initial Phase 2 Development Strategy Septerna, Inc. announced positive results from its Phase 1 clinical trial evaluating SEP-631, a potent and selective oral negative allosteric modulator (NAM) of Mas-related G protein-coupled receptor X2 (MRGPRX2). These findings are consistent with the insurmountable NAM mechanism of SEP-631 observed preclinically and support potent target engagement and functional blockade of MRGPRX2 signaling in humans, providing clinical proof-of-mechanism. Phase 2 Development Strategy: Septerna plans to initiate a Phase 2b clinical trial of SEP-631 in chronic spontaneous urticaria (CSU) in the second half of this year, following the completion of ongoing long-term toxicology studies. Following the CSU study initiation, the company also plans to pursue an open-label study in chronic inducible urticaria (CIndU), specifically in patients with symptomatic dermatographism. In a Phase 1 clinical trial, SEP-631 demonstrated favorable tolerability, once-daily pharmacokinetics and pharmacodynamic evidence of MRGPRX2 pathway inhibition. Duyuru • Jan 09

Septerna Announces Discontinuation of SEP-786 Phase 1 Clinical Trial and Plans to Advance Next-Generation Oral Small Molecule PTH1R Agonist Septerna, Inc. announced its decision to discontinue the Phase 1 single- and multiple-ascending dose (SAD/MAD) clinical trial of SEP-786 in healthy volunteers. SEP-786 is an oral small molecule agonist of the parathyroid hormone 1 receptor (PTH1R) being developed for the treatment of hypoparathyroidism. Septerna’s decision follows the observation of two unanticipated severe (Grade 3) events of elevated unconjugated bilirubin in the MAD portion of the Phase 1 trial, both of which were without elevations in ALT, AST, and GGT liver enzyme levels. Dosing was discontinued for both study participants, and the bilirubin elevations were reversible. Importantly, there were no events of liver injury, cholestasis, or hemolysis across all participants, and there were no serious adverse events (SAEs) in the Phase 1 trial. In completed 28-day preclinical toxicology studies, SEP-786 was generally well-tolerated, without predicted risk of bilirubin elevation. In response to these Phase 1 events, Septerna has initiated non-clinical studies to investigate the underlying mechanism behind the observed effect. Duyuru • Jan 06
