**Exhibit 99.1**

**Septerna Highlights Business Progress and Reports Second Quarter 2025 Financial Results** 

*Advancing Selection of Next-Generation Oral Small Molecule PTH1R Agonist for Clinical Development* 

*Initiating Phase 1 Trial for SEP-631, MRGPRX2 NAM Program, for Mast Cell Diseases*

*Updated Cash Runway Expected to Support Operating Plans at Least into 2029*

**<br>SOUTH SAN FRANCISCO, Calif. – August 11, 2025** – Septerna, Inc. (Nasdaq: SEPN), a biotechnology company pioneering a new era of G protein-coupled receptor (GPCR) drug discovery, today highlighted key business updates and upcoming milestones and reported financial results for the second quarter ended June 30, 2025.

"We are executing effectively across our portfolio, with each program nearing important milestones," said Jeffrey Finer, M.D., Ph.D., chief executive officer and co-founder of Septerna. "Our next-generation PTH1R agonist program for hypoparathyroidism is progressing through preclinical studies as we work toward selecting a development candidate in the third quarter with plans to start a Phase 1 clinical trial in the first half of 2026. In the near term, we are excited to initiate first-in-human studies for SEP-631, our oral small molecule in development for mast cell-driven diseases. With our robust financial position, bolstered by our collaboration with Novo Nordisk which became effective in July, and our strong R&D capabilities, we believe we are well positioned to pursue multiple programs towards our goal of delivering innovative oral small molecule therapies that can meaningfully improve patient outcomes."

**Corporate Overview and Anticipated Milestones** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**PTH1R Agonist Program:** 

oSepterna continues to advance its oral small molecule parathyroid hormone 1 receptor (PTH1R) agonist program with the goal of providing full-day calcium control in hypoparathyroidism patients. The company is tracking towards the selection of a next-generation PTH1R agonist development candidate in the third quarter of 2025 and plans to provide an update later this quarter. Following the successful completion of preclinical development activities, the company plans to commence a Phase 1 clinical trial in the first half of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**SEP-631 MRGPRX2 NAM Program:** 

oSepterna is initiating a Phase 1 clinical trial of SEP-631 to assess safety, tolerability, pharmacokinetics and pharmacodynamics (through an icatibant skin challenge) in healthy volunteers in the third quarter of 2025. SEP-631 is a selective oral small molecule MRGPRX2 negative allosteric modulator (NAM) in development for the treatment of mast cell diseases, including chronic spontaneous urticaria.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**TSHR NAM Program:** 

oSepterna continues to make progress on its TSHR NAM program, moving multiple lead compounds closer to development candidate selection with the goal of delivering a potential disease-modifying oral treatment for Graves' disease and thyroid eye disease.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Discovery Programs:** 

oSepterna continues to advance discovery-stage programs utilizing its Native Complex Platform™ across multiple therapeutic areas.

**Collaboration Agreement with Novo Nordisk**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•On July 1, 2025, the previously announced global collaboration and license agreement between Septerna and Novo Nordisk became effective, initiating joint research and development efforts to discover, develop, and commercialize multiple potential oral small molecule therapies for obesity, type 2 diabetes, and other cardiometabolic diseases based on certain specified molecular targets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In connection with the effectiveness of the global collaboration and license agreement, Septerna received the $195 million upfront payment in July 2025. Septerna expects to recognize revenue for this upfront payment over the anticipated duration of the company's participation in the research and development programs. More details about the global collaboration and license agreement can be found in the company's press release and Current Report on Form 8-K filed on May 14, 2025.

**Business Highlights**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Septerna announced the promotion of Chief Operating Officer (COO) Liz Bhatt, MS, MBA, to President, effective August 1, 2025. Ms. Bhatt joined Septerna in 2022 as COO, bringing more than 30 years of strategy, deal-making and company-building experience across a range of biotech and pharmaceutical companies to the company. In her role, Ms. Bhatt will continue to have oversight of business development, alliance management, portfolio strategy, commercialization and information technology.

"Liz has been an exceptional leader at Septerna from day one, playing a pivotal role in driving the growth of both our company and our pipeline," added Dr. Finer. "Among many accomplishments, her leadership was instrumental in securing our multi-billion-dollar strategic partnership with Novo Nordisk, guiding Septerna through a successful upsized and oversubscribed IPO in 2024, and building out key functions across the business. On behalf of the entire organization and the Board, I want to congratulate Liz on this well-earned promotion."
