Completed enrollment in 12-week Phase 2a study of oral GLP-1 receptor agonist, GSBR-1290

Topline data from Phase 2a and Phase 1b multiple ascending dose study of GSBR-1290 expected in latter half of fourth quarter 2023

SAN FRANCISCO, Aug. 10, 2023 (GLOBE NEWSWIRE) -- Structure Therapeutics Inc. (NASDAQ: GPCR), a clinical-stage global biopharmaceutical company developing novel oral small molecule therapeutics for metabolic and cardiopulmonary diseases, today reported financial results for the second quarter June 30, 2023, and highlighted recent corporate achievements.

“We have continued our momentum and are on track to report topline data from our fully-enrolled Phase 2a study of GSBR-1290 in individuals living with Type 2 diabetes or obesity toward the end of the year,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “With the recent announcement of Dr. Ted Love joining our Board, key milestones ahead and our strong cash runway, we believe we are well-positioned to execute on building our oral incretin franchise and have begun activities to prepare for a global Phase 2b study of GSBR-1290 in 2024.”

Recent Highlights and Upcoming Milestones

GSBR-1290 for Type 2 Diabetes Mellitus (T2DM) and Obesity: Completed patient enrollment in the Phase 1b multiple-ascending dose (MAD), Phase 2a, and Japanese ethnobridging studies. Topline data are expected to be announced in latter half of fourth quarter 2023.

• Structure Therapeutics presented data from the Phase 1 single ascending dose clinical study and preclinical data of GSBR-1290 at the 2023 American Diabetes Association (ADA) Annual Meeting in June 2023.

• The Company recently completed enrollment in the Phase 2a study of GSBR-1290, enrolling 94 adult participants, including 40 individuals who are overweight or obese and otherwise healthy and 54 individuals who are overweight or obese with T2DM. The study evaluates the efficacy, safety, tolerability, and pharmacokinetics (PK) of GSBR-1290 over twelve weeks.

• The Company recently completed enrollment of the ethnobridging study of GSBR-1290. Twelve healthy adult Japanese participants, randomized 3:1 to GSBR-1290 or placebo, and six healthy non-Japanese participants were enrolled to evaluate the safety, tolerability, and PK of single and multiple doses of GSBR-1290 over four weeks.

• The Company is also planning to initiate a formulation bridging study to evaluate a tablet formulation of GSBR-1290 before the end of 2023 and has begun a wide range of other enabling activities in preparation for the planned global Phase 2b study in 2024.
  

Next-generation combination GLP-1R candidates

• Beyond GSBR‑1290, the Company continues to develop next generation combination GLP‑1R candidates, including dual GLP‑1R/GIPR agonists and amylin agonists, each designed with customized properties to achieve additional benefits.
  

ANPA-0073 and LTSE-2578 for Cardiopulmonary Diseases

• The Company presented scientific posters of the discovery and Phase 1 clinical data of ANPA-0073, an oral small molecule agonist of the apelin/APJ receptor and the structure-based drug discovery of LTSE-1578, an oral small molecule antagonist of the LPAR1 receptor for pulmonary diseases at the 2023 American Thoracic Society (ATS) International Conference in May 2023.
  

Corporate

• Structure Therapeutics recently announced the appointment of Ted W. Love, M.D. to its Board of Directors. Dr. Love brings more than 30 years of experience in the biopharmaceuticals industry and currently chairs the Biotechnology Innovation Organization (BIO) Board.
