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

Year-end cash balance of $467.3 million expected to fund operations and
key clinical milestones through 2026

SAN FRANCISCO, March 08, 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 fourth quarter and full year ended December 31, 2023, and highlighted recent corporate achievements.

“In 2023 we demonstrated clear proof-of-concept with our lead GLP-1 receptor agonist, GSBR-1290, for obesity and type 2 diabetes. As a differentiated oral small molecule we have the scalability and manufacturing advantages to potentially meet the significant unmet need currently observed in the GLP-1 space,” said Raymond Stevens, Ph.D., Founder and CEO of Structure Therapeutics. “With a year-end cash balance of $467.3 million providing runway through the end of 2026, we are well-positioned to initiate and complete our Phase 2b trials for GSBR-1290 and accelerate development of our oral small molecule programs targeting amylin, GIP, and apelin receptors.”

Recent Highlights and Upcoming Milestones

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

• In December 2023, the Company reported clinically meaningful data from the Phase 2a study in T2DM demonstrating significant reductions in hemoglobin A1c (HbA1c) and weight at 12 weeks. Interim Phase 2a data from the obesity cohort demonstrated significant reduction in weight at 8 weeks. Across both cohorts, GSBR-1290 was generally well-tolerated with no treatment-related serious adverse events over 12 weeks and low study discontinuation rates due to adverse events related to study drug (2.8% in T2DM and 0% in 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. This study is fully enrolled and data are expected in the latter half of the second quarter of 2024.
• In preparation for later stage clinical trials, a formulation bridging and titration optimization study to evaluate capsule versus tablet pharmacokinetics (PK) and explore different titration regimens of GSBR-1290 is ongoing. This study is fully enrolled and data are expected in the latter half of the second quarter of 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.
  

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

• Oral Small Molecule Amylin Program: The Company is developing amylin agonists for 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 second half 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 its Phase 2 ready ANPA-0073, a biased agonist targeting APJR used in combination with weight loss medicines, for 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.
  

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 the second quarter of 2024.
  

Corporate

• In 2023, the Company raised approximately $485.0 million of equity capital: $185.0 million in gross proceeds from the initial public offering in February, and $300.0 million in gross proceeds from the private placement equity financing in October.
  

Fourth Quarter and Full Year 2023 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $467.3 million at December 31, 2023. The Company expects its current cash, cash equivalents and short-term investments to fund operations and expected key clinical milestones through at least 2026.

R&D Expenses: Research and development (R&D) expenses for the fourth quarter of 2023 were $20.0 million, as compared to $8.4 million for the same period in 2022. For the year ended December 31, 2023, R&D expenses were $70.1 million, as compared to $36.2 million for the full year 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 (G&A) expenses for the fourth quarter of 2023 were $11.0 million, as compared to $4.6 million for the same period in 2022. For the year ended December 31, 2023, G&A expenses were $32.7 million, as compared to $16.4 million for the full year 2022. 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 fourth quarter of 2023 totaled $24.5, with non-cash stock-based compensation expense of $2.1 million, compared to $11.9 million for the fourth quarter of 2022 with non-cash stock-based compensation expense of $0.6 million. For the year ended December 31, 2023, net loss totaled $89.6 million, with non-cash stock-based compensation expense of $8.2 million, compared to $51.3 million for the full year 2022 with non-cash stock-based compensation expense of $2.5 million.
