Announced positive results from Phase 1b clinical study of oral GLP-1 receptor agonist, GSBR-1290, demonstrating significant weight loss supporting once-daily dosing and an encouraging safety and tolerability profile

Topline data from GSBR-1290 Phase 2a diabetes cohort expected in December 2023; Topline data from Phase 2a obesity cohort expected in first half of 2024

Completed $300 million financing; expected to extend funding through the end of 2026

SAN FRANCISCO, Nov. 14, 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 third quarter ended September 30, 2023, and highlighted recent corporate achievements.

“Our recent Phase 1b data support the potential of GSBR-1290 as a promising, differentiated oral GLP-1 receptor agonist with once-daily dosing,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “Following the completion of our recent $300 million equity financing in October, we believe we are well positioned to advance and accelerate the development of GSBR-1290 as well as our entire oral incretin franchise.”

Recent Highlights and Upcoming Milestones

GSBR-1290 for Type 2 Diabetes Mellitus (T2DM) and Obesity

• The Company reported topline data from the 28-day Phase 1b multiple ascending dose (MAD) study in September 2023. GSBR-1290 demonstrated significant weight loss of up to 4.9% (placebo-adjusted) supporting once-daily dosing, and an encouraging safety profile with no adverse event-related discontinuations.
• The Company expects to report topline data from the type 2 diabetes (T2DM) cohort of the Phase 2a study in December 2023, along with results from the Japanese ethno-bridging study of GSBR-1290.
• Topline data from the obesity cohort of the Phase 2a study are expected in the first half of 2024.
• The Company plans to initiate global Phase 2b studies in T2DM and obesity in the second half of 2024. In preparation for these studies, Structure has initiated a formulation bridging study to evaluate a tablet formulation of GSBR-1290.

Next-generation combination GLP-1R candidates

• The Company continues to develop next generation combination GLP‑1R candidates, including dual GLP‑1R/GIPR agonists and amylin receptor agonists, each designed with customized properties to achieve additional benefits. Development candidates for each program are expected to be selected in 2024.
  

Corporate

• In October 2023, Structure completed a private placement equity financing, raising approximately $300 million in gross proceeds before deducting placement agent fees and other private placement expenses.
  

Third Quarter 2023 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $205.4 million at September 30, 2023. The Company expects its current cash, cash equivalents and short-term investment, together with the $300 million in gross proceeds from the financing completed in October 2023, to fund operations and expected key clinical milestones through at least 2026.

R&D Expenses: Research and development expenses were $17.5 million for the quarter ended September 30, 2023, as compared to $9.2 million for the same period in 2022. The increase was primarily due to the advancement of the Company’s GLP-1R franchise and other research programs, clinical study activities and increases related to employee expenses, primarily due to an increase in personnel.

G&A Expenses: General and administrative expenses were $8.6 million for the quarter ended September 30, 2023, as compared to $3.5 million for the same period in 2022. The increase was primarily due to increases in professional services associated with employee related expenses as the Company expanded its infrastructure to drive and support the growth in its operations as a publicly-traded company.

Net Loss: Net loss totaled $23.9 million for the quarter ended September 30, 2023, with non-cash stock-based compensation expense of $1.9 million, compared to $12.4 million for the same period in 2022 with non-cash stock-based compensation expense of $0.6 million.
