Topline GSBR-1290 Phase 2a 12-week obesity data on track for June 2024

Phase 2b study in obesity expected to begin as planned in the fourth quarter 2024

Plan to initiate dosing in first-in-human Phase 1 clinical trial of oral small molecule LPA1R Antagonist, LTSE-2578, for idiopathic pulmonary fibrosis in June 2024

SAN FRANCISCO, May 09, 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 first quarter ended March 31, 2024, and highlighted recent corporate achievements.

“We look forward to our 12 week Phase 2a data for GSBR-1290 in June, and moving forward with our 36 week Phase 2b obesity study later this year,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “With tremendous unmet need including more than 100 million people in the United States and more than 800 million people worldwide living with obesity, we believe GSBR-1290 is uniquely positioned as an oral, non-peptide small molecule GLP-1 receptor agonist that can be manufactured at scale and significantly help address the growing obesity epidemic, which current peptide GLP-1s are not able to do.”

Upcoming Milestones

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

• Topline data from the obesity cohort of the Phase 2a study, including full 12-week efficacy data for 40 participants and safety and tolerability for all 64 participants, are expected in June 2024.
• In preparation for later stage clinical trials, the company is conducting a formulation bridging and titration study to evaluate capsule versus tablet pharmacokinetics (PK) and explore different titration regimens of GSBR-1290. High level PK study results are expected in June 2024.
• The Company plans to initiate a global Phase 2b obesity study of GSBR-1290 in the fourth quarter of 2024.
• The Company plans to initiate a Phase 2 study in T2DM in the second half of 2024.

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

• Oral Small Molecule Amylin Program: The Company is developing amylin receptor agonists for potential use either alone or in combination with GLP-1R agonists to treat obesity and associated diseases, and expects to select a development candidate in the fourth quarter of 2024.
• Oral Small Molecule GIPR Program: The Company 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 Apelin Receptor (APJR) Program: The Company 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). The Company has completed a Phase 1 single-ascending and multiple-ascending dose study, in which ANPA-0073 was generally well-tolerated with no serious adverse event reported.
  

Oral Small Molecule LPA1R Program for Idiopathic Pulmonary Fibrosis (IPF)

• The Company is developing LTSE-2578, an oral small molecule antagonist that targets lysophosphatidic acid 1 receptor (LPA1R). Preclinical studies have demonstrated substantial anti-fibrotic activity in mouse models of fibrotic lung disease, and the Company expects to initiate a first-in-human study of LTSE-2578 in June 2024.
  

First Quarter 2024 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $436.4 million on March 31, 2024. The Company expects its current cash, cash equivalents and short-term investments to fund projected operations through at least 2026.

R&D Expenses: Research and development (R&D) expenses for the first quarter of 2024 were $20.7 million, as compared to $13.1 million for the same period in 2023. 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 (G&A) expenses for the first quarter of 2024 were $11.3 million, as compared to $6.5 million for the same period in 2023. The increase was primarily due to increases in professional services and 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 for the first quarter of 2024 totaled $26.0 million, with non-cash share-based compensation expense of $2.7 million, compared to $18.0 million for the first quarter of 2023 with non-cash share-based compensation expense of $2.5 million.
