Insights

Clinical development expert

Topline obesity trial readouts due by year-end 2025; oral amylin program entering first‑in‑human work.

Aleniglipron has two Phase 2 programs, ACCESS and ACCESS II, with planned 36‑week topline readouts by year-end 2025. Both studies enrolled adults with obesity or overweight and comorbidities and include higher‑dose cohorts and extension periods for additional safety and efficacy data.

ACC G‑2671 expects Phase 1 initiation by year-end 2025, and ACCG‑3535 was declared a second development candidate with preclinical efficacy and combination data presented. Watch the actual 36‑week efficacy and safety outcomes and any disclosed primary endpoint results over the next weeks; those metrics will determine next regulatory and Phase 3 planning steps.

Financial and program-risk analyst

Strong cash runway and rising R&D spend support late‑stage readouts and early clinical starts.

Cash, cash equivalents and short‑term investments total $799.0 million as of September 30, 2025, expected to fund operations through at least 2027. R&D expenses rose to $59.0 million in Q3 2025, reflecting clinical activity and personnel increases.

The balance to watch: topline efficacy and safety readouts by year-end 2025 and disclosure of primary endpoint outcomes. If readouts are favourable, the company could proceed to Phase 3 planning; if not, funding duration and R&D prioritization become the key near‑term variables.

SAN FRANCISCO, Nov. 06, 2025 (GLOBE NEWSWIRE) -- Structure Therapeutics Inc. (NASDAQ: GPCR), a clinical-stage global biopharmaceutical company developing novel oral small molecule therapeutics for metabolic diseases, with a focus on obesity, today reported financial results for the third quarter ended September 30, 2025, and provided a business update.

“We are on schedule to report topline data by year-end 2025 from both the ACCESS and ACCESS II studies of aleniglipron, our once-daily oral small molecule GLP-1 receptor agonist for the treatment of obesity,” said Raymond Stevens, Ph.D., CEO of Structure Therapeutics. “In parallel, we plan to initiate a Phase 1 study of ACCG-2671, which we believe to be the most advanced oral small molecule amylin receptor agonist in development, and we have declared a second amylin development candidate to further enhance our leadership position with oral small molecules engaging this attractive target. We believe the future of obesity treatment lies in multiple options and includes oral, combinable, and broadly accessible therapies—principles that define and differentiate our pipeline and development strategy. These upcoming milestones mark meaningful progress toward realizing that vision.”

Recent and Upcoming Milestones

Aleniglipron (GSBR-1290) - Oral Small Molecule Selective Glucagon-Like Peptide 1 (GLP-1) Receptor Agonist for the Treatment of Obesity and Overweight

ACCESS and ACCESS II Studies on track for topline 36-week data readouts by year-end 2025

• ACCESS is a Phase 2b randomized placebo-controlled, 36-week study that enrolled approximately 220 adults with obesity, or overweight with at least one weight-related comorbidity, evaluating doses up to 120 mg of aleniglipron with a four-week titration schedule. An Open Label Extension of the ACCESS study is ongoing.
• ACCESS II is a Phase 2 randomized placebo-controlled study that enrolled approximately 80 adults with obesity, or overweight with at least one weight-related comorbidity, evaluating higher doses of aleniglipron (180 mg and 240 mg) with a four-week titration schedule. Following the initial 36-week evaluation, patients continue in the study to 44 weeks, which allows for collection of an additional eight weeks of double-blinded safety, tolerability, and efficacy data. 
  
  

Three supplementary studies ongoing to generate additional data to competitively position aleniglipron and further support the design of the Phase 3 program

• Study to assess a maintenance switching strategy from an approved injectable GLP-1 receptor agonist to aleniglipron – Enrollment is ongoing in this maintenance switching study which is evaluating the transition from an approved injectable GLP-1 receptor agonist to once-daily oral aleniglipron for weight loss maintenance. This study will assess the starting dose and the weight loss maintenance over 12 weeks.
• Body composition study – This fully-enrolled Phase 2 randomized placebo-controlled study is assessing the effect of aleniglipron on body fat loss measured via DEXA over a 40-week evaluation period. These data will be used to support the inclusion of body composition endpoints into the Phase 3 program.
• Study in patients with type 2 diabetes mellitus (T2DM) with obesity/overweight – Enrollment is ongoing in this Phase 2 randomized placebo-controlled study which is assessing aleniglipron at doses of up to 240 mg in patients living with obesity or overweight with T2DM. Data from the 38-week study will be used to support the inclusion of a cohort of patients with T2DM in the Phase 3 obesity program.
  
  

Oral Small Molecule Amylin Receptor Agonists for the Treatment of Obesity or Overweight with Comorbidities

• ACCG-2671 – Investigational new drug enabling activities for ACCG-2671 are ongoing, with the initiation of a first-in-human Phase 1 clinical study expected by year-end 2025.
• ACCG-3535 – A second dual amylin and calcitonin receptor agonist development candidate, ACCG-3535, has been selected. ACCG-3535 is a unique chemical structure from ACCG-2671. Preclinical ACCG-3535 data were recently presented at Obesity Week 2025 demonstrating high binding affinity to human amylin and calcitonin receptors and balanced potency in human amylin and calcitonin receptor functional assays. In addition, ACCG-3535 demonstrated robust food intake suppression and significant, dose-dependent body weight reduction as a monotherapy in diet-induced obese rats. Combination therapy with semaglutide (both concurrently and as a subsequent add-on to semaglutide) resulted in superior weight loss compared to semaglutide or ACCG-3535 monotherapy.
  
  

Third Quarter 2025 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $799.0 million as of September 30, 2025. The Company expects its current cash, cash equivalents and short-term investments to fund projected operations and key clinical milestones through at least 2027. For aleniglipron, this includes costs related to the ongoing ACCESS and ACCESS II studies, extension studies, the supplementary studies, and Phase 3 readiness activities, but excludes Phase 3 registrational studies.

Research and Development (R&D) Expenses: R&D expenses for the third quarter of 2025 were $59.0 million, as compared to $32.6 million for the same period in 2024. The increase in R&D expenses was primarily due to increases related to clinical trial costs, preclinical research and development expenses and employee expenses (primarily due to an increase in personnel) to support the advancement of our GLP-1R franchise including aleniglipron.

General and Administrative (G&A) Expenses: G&A expenses for the third quarter of 2025 were $14.8 million, as compared to $13.2 million for the same period in 2024. The increase in G&A expenses was primarily due to increases in employee expenses as we expanded our infrastructure to drive and support the growth in our operations as a publicly-traded company.

Net Loss: Net loss for the third quarter of 2025 totaled $65.7 million, with non-cash share-based compensation expense of $7.5 million, compared to $34.0 million for the third quarter of 2024 with non-cash share-based compensation expense of $6.0 million.
