Conference Call to discuss GSBR-1290 ACCESS development program today at 4:30 p.m. ET

SAN FRANCISCO, Nov. 13, 2024 (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 third quarter ended September 30, 2024, and highlighted recent corporate achievements.

“We are in a period of great momentum and execution at Structure Therapeutics, having begun our next phase of development with GSBR-1290,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “The ACCESS and ACCESS II studies are designed to generate a comprehensive data set that we believe will provide additional insights into the differentiated profile of GSBR-1290 as a potential best-in-class oral small molecule GLP-1 receptor (GLP1-R) agonist. We also plan to declare our first oral small molecule amylin development candidate later this quarter. We look forward to 2025 as a pivotal year for Structure.”

Recent and Upcoming Milestones

Oral Small Molecule Selective GLP-1R agonist for Obesity (GSBR-1290)

• Structure announced today a comprehensive development program to further evaluate GSBR-1290 in adults living with obesity or overweight, consisting of the Phase 2b ACCESS study and the Phase 2 ACCESS II study. Structure designed the ACCESS and ACCESS II studies to generate a robust dataset to enable optimized Phase 3 clinical development with the goal of bringing GSBR-1290 to patients as rapidly as possible.
  • ACCESS aims to enroll approximately 220 adults living with obesity, or overweight with a weight-related comorbidity, and is designed to evaluate doses up to 120 mg and optimize titration regimens of GSBR-1290 over 36 weeks, following a four-week titration schedule.
  • ACCESS II aims to enroll approximately 82 adults living with obesity, or overweight with a weight-related comorbidity, and is designed to evaluate higher doses (180 mg and 240 mg) of GSBR-1290 over 36 weeks.
• The first patients have been dosed in the Phase 2b ACCESS study and Structure expects to dose the first patient in ACCESS II by the end of 2024. Topline data from the ACCESS and ACCESS II studies are expected in the fourth quarter of 2025.

Oral Small Molecule GLP-1R Combination Programs: Amylin, GIPR, Apelin Receptor (APJR)

• Oral Small Molecule Amylin Program: Structure Therapeutics is also developing amylin receptor agonists (dual amylin and calcitonin receptor agonists) for potential use either alone or in combination with GLP-1R agonists to treat obesity and associated diseases. Structure recently presented preclinical data related to its amylin program at ObesityWeek® and expects to select a development candidate by the end of 2024.
• Oral Small Molecule GIPR Program: Structure Therapeutics is developing a GIPR selective agonist and GLP‑1R/GIPR combinations to treat obesity and associated diseases, and expects to select a development candidate in the first half of 2025.
• Oral Small Molecule APJR Program: Structure Therapeutics is evaluating ANPA-0073, a Phase 2 ready biased APJR agonist for potential selective or muscle-sparing weight loss. ANPA-0073 is also being evaluated for idiopathic pulmonary fibrosis (IPF). Structure Therapeutics has completed a Phase 1 single-ascending and multiple-ascending dose study, in which ANPA-0073 was generally well-tolerated with no serious adverse events reported. Structure Therapeutics is conducting long term chronic GLP-toxicology studies expected to be completed in 2025.
  

Third Quarter 2024 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $915.3 million on September 30, 2024. The Company expects its current cash, cash equivalents and short-term investments to fund projected operations and key clinical milestones through at least 2027, including all GSBR-1290 studies for Phase 3 readiness but excluding Phase 3 registrational studies.

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2024 were $32.6 million, as compared to $17.5 million for the same period in 2023. The increase was primarily due to increases in research programs and employee expenses related to increases in personnel, as well as the advancement of the Company’s GLP-1R agonist franchise.

General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2024 were $13.2 million, as compared to $8.6 million for the same period in 2023. The increase was primarily due to increases in employee related expenses and professional services as the Company expanded its infrastructure to drive the growth in its operations as a publicly-traded company.

Net Loss: Net loss for the third quarter of 2024 totaled $34.0 million, with non-cash share-based compensation expense of $6.0 million, compared to $23.9 million for the third quarter of 2023 with non-cash share-based compensation expense of $1.9 million.
