Structure Therapeutics Inc. to Report Data from ACCESS Clinical Program of Oral Small Molecule GLP-1 Receptor Agonist, Aleniglipron, on December 8, 2025

Structure Therapeutics Inc. announced positive topline data from the ACCESS clinical program of aleniglipron for the treatment of people living with obesity and/or overweight with at least one weight related co-morbidity. This includes 36-week data from the core Phase 2b ACCESS study and the ongoing exploratory ACCESS II study, and interim data from the ongoing Body Composition study and the ACCESS open label extension (OLE) study. Aleniglipron is an investigational orally-available, once-daily, nonpeptide small molecule agonist of the glucagon-like-peptide-1 (GLP-1) receptor designed to address patient needs and accessibility. In the core Phase 2b ACCESS study, aleniglipron achieved a clinically meaningful and statistically significant placebo-adjusted mean weight loss of 11.3% (27.3 lbs, p<0.0001) at the 120 mg dose at 36 weeks and across all active arms had a 10.4% adverse event (AE)-related treatment discontinuation rate. In the exploratory ACCESS II study, aleniglipron achieved a placebo-adjusted mean weight loss up to 15.3% (35.5 lbs, p<0.0001) with 240 mg dose at 36 weeks. Aleniglipron demonstrated a tolerability profile consistent with the GLP-1 receptor agonist class, and a compelling off-target safety profile. Together, these positive findings support the advancement of aleniglipron into Phase 3 clinical development. The core 36-week Phase 2b ACCESS study was a randomized, double-blind, placebo-controlled, Phase 2b dose-range finding clinical study that enrolled 230 adult participants living with obesity (body mass index (BMI) = 30 kg/m2), or overweight (BMI = 27 kg/m2) with at least one weight-related comorbidity. All participants were randomized 3:1 (active:placebo) and started at 5 mg of aleniglipron (or placebo) with a 4-week titration schedule, reaching target doses of 45 mg, 90 mg or 120 mg once-daily. Each of the three doses in the ACCESS study achieved statistical significance on the primary endpoint and all key secondary endpoints. At Week 36, key secondary endpoints in the study show that 86% of participants in the aleniglipron 120 mg dose cohort achieved at least 5% weight loss and 70% achieved at least 10% weight loss. In addition, aleniglipron demonstrated clinically meaningful improvements in systolic blood pressure (-6.4 to -7.5 mmHg) and HbA1c (-0.28% to -0.37%). Aleniglipron demonstrated a tolerability profile consistent with the GLP-1 receptor agonist class following repeated, once-daily dosing of up to 120 mg in the Phase 2b ACCESS study. As expected for the GLP1-RA drug class, the most common AEs were gastrointestinal (GI)-related and the two most common AEs in the titration phase were nausea and vomiting. AEs were generally observed early in treatment. In the Phase 2b ACCESS study, the AE-related treatment discontinuation rate ranged from 7.7% - 13.3% between all doses, with a mean 10.4% across all active arms in the study. ACCESS II is a randomized, double-blind, placebo-controlled, clinical study of aleniglipron that enrolled 85 adult participants living with obesity, or overweight with at least one weight-related comorbidity. The study was designed to evaluate two higher doses of aleniglipron. Participants started at 5 mg of aleniglipron (or placebo) and followed a 4-week titration schedule up to target doses of 120 mg, 180 mg and 240 mg. The 44-week study remains ongoing, with data from a prespecified 36-week analysis currently available. At 36 weeks, each of the three dose cohorts in the ACCESS II study met statistical significance compared to placebo. Aleniglipron demonstrated a tolerability profile consistent with the GLP-1 receptor agonist class following repeated, once- daily dosing of up to 240 mg. As expected for the GLP1-RA drug class, the most common AEs were GI-related and the two most common AEs in the titration phase were nausea and vomiting. AEs were generally observed early in treatment. Body Composition Study - Evaluating lower 2.5 mg starting dose Structure Therapeutics is currently conducting a randomized, placebo-controlled body composition study that enrolled 71 adult participants to assess the effect of aleniglipron (up to 120 mg) on body fat loss over a 40-week evaluation period. Participants in the aleniglipron treatment arm start at a 2.5 mg dose, and titrate up monthly to a target dose of 120 mg. Data from a pre-specified interim analysis after a median follow-up time of approximately 10 weeks showed that starting at a lower dose of 2.5 mg for the first four weeks meaningfully improved tolerability compared to what was observed at a starting titration dose of 5 mg in the ACCESS and ACCESS II studies, with no AE-related treatment discontinuations observed at the initial 2.5 mg dose or the subsequent 5 mg dose. ACCESS Open-Label Extension Study - Following randomized 36-week period, evaluating lower 2.5mg starting dose Following the 36-week randomized controlled portion of the Phase 2b ACCESS study, the majority of eligible ACCESS participants enrolled in ACCESS OLE. An initial analysis from the ongoing OLE demonstrates continuing weight loss in all dose cohorts out to 44 weeks, showing no evidence of weight loss plateau. In the ACCESS OLE, participants who received placebo in the initial double-blind portion transitioned to aleniglipron at a starting dose of 2.5 mg and titrate monthly to a target dose of 120 mg. Initial data from this group of participants after eight weeks of treatment are consistent with the findings from the body composition study, showing that starting at a 2.5 mg titration dose meaningfully improved tolerability compared to what was observed in the starting 5 mg titration dose in ACCESS and ACCESS II studies, with no AE-related treatment discontinuations at the initial 2.5 mg or the subsequent 5 mg dose. Aleniglipron Safety Aleniglipron demonstrated a compelling safety profile across all studies. Importantly, there were no cases of drug-induced liver injury, no persistent liver enzyme elevations, and no QTc prolongation across all aleniglipron studies. Phase 3 Preparation Data from ACCESS, ACCESS II, body composition, and the ACCESS OLE studies provide a strong foundation to advance aleniglipron into Phase 3 clinical development. The Company plans to request a Type B End-of-Phase 2 meeting with the United States Food and Drug Administration (FDA) in the first half of 2026 to finalize the Phase 3 design, which is currently designed with a starting titration dose of 2.5 mg with the intent to evaluate multiple doses up to 240 mg. Structure Therapeutics anticipates initiating the Phase 3 program by mid-2026.

Structure Therapeutics Inc. Provides Comprehensive GSBR-1290 Program Update

Structure Therapeutics Inc. provided a comprehensive development program update for its highly selective oral GLP-1 receptor antagonist, GSBR-1290. Phase 2a Study in Diabetes and Obesity The randomized, double-blind, 12-week placebo-controlled Phase 2a clinical trial has enrolled a total of 94 participants to date, including 60 participants randomized to GSBR-1290. The T2DM cohort enrolled 54 participants, randomized to GSBR-1290 45 mg (n=10) or 90 mg (n=26), or placebo (n=18), dosed once daily. The obesity cohort initially enrolled 40 individuals randomized to GSBR-1290 120 mg (n=24) or placebo (n=16), once-daily. An additional 24 participants are currently being enrolled in the obesity arm as previously announced and will also be randomized 3:2 to GSBR-1290 or placebo. The primary endpoint of the Phase 2a study is safety and tolerability of GSBR-1290. Key secondary endpoints include reduction in weight for both cohorts, as well as reduction in HbA1c for the T2DM cohort. Safety and Tolerability Results GSBR-1290 demonstrated encouraging safety and tolerability following repeated, daily dosing for all doses studied (up to 120 mg) in the obesity and T2DM cohorts. The majority (88 to 96%, depending on study arm) of adverse events (AEs) reported were mild to moderate. There were no serious adverse events (SAEs) related to study drug. As expected for this mechanism of action, leading AEs were gastrointestinal-related. The two most common AEs were nausea and vomiting. There were no cases of elevated liver enzymes in the obesity cohort. One participant in the T2DM treatment group experienced an event of elevated liver enzymes without an increase in bilirubin initially at day 8 while receiving 5 mg of study drug. This participant was diagnosed with fatty liver disease while in the study. Of the 60 participants dosed with GSBR-1290, only one participant discontinued the study due to AEs related to study drug (none in the obesity cohort and one (2.8%) in the T2DM cohort). GSBR-1290 demonstrated clinically meaningful activity in both T2DM and obesity cohorts. In the T2DM cohort, there was a statistically significant HbA1c reduction (- 1.01 to -1.02%, placebo-adjusted) at Week 12 (Table 2). The study demonstrated a statistically significant and clinically meaningful reduction in weight at Week 12 (-3.26% to 3.51%, placebo-adjusted) (Table 3). Weight loss continued to decrease through Week 12. Results of the interim analysis in the obesity cohort, showed a statistically significant and clinically meaningful decrease in weight at Week 8 (-4.74%, placebo-adjusted) (table 4). Weight loss continued to decrease throughout the eight weeks of treatment. Results from Phase 1 Japanese Bridging Study: The 4-week Phase 1 Japanese ethnobridging study included healthy lean Japanese participants randomized to GSBR-1290 (n=9) and placebo (n=3), and healthy lean non-Japanese participants receiving GSBR-1290 (n=6). GSBR-1290 demonstrated a substantial weight reduction in Japanese participants (-3.91% on GSBR-1290 vs -1.67% placebo) and in non-Japanese participants (-5.13% not placebo-adjusted), with no discontinuations or dose reductions, and no SAEs. These data will be used for regulatory interactions in Japan in preparation for potential future global studies of GSBR-1290. Results from 6- and 9-Month Toxicology Studies: In preparation for Phase 2b development with longer durations of treatment, Structure has completed 6-month (rodent) and 9-month (non-human primate) toxicology studies to evaluate the safety of GSBR-1290. No major findings were observed in either study, with no test article-related changes observed in the liver, including ALT/AST, at all doses, and a >100 fold safety window at the 120 mg therapeutic dose. GSBR-1290 Next Steps: Full 12-week results from the Phase 2a obesity cohort (n=64), including data from the additional 24 participants currently being enrolled, are expected in the second quarter of 2024. Structure plans to initiate a Phase 2b obesity study of GSBR-1290 in the second half of 2024. The study is planned to include at least 275 individuals across the United States and Europe and will include multiple modified dose titration regimens to optimize efficacy and tolerability. An additional Phase 2 study in T2DM is also planned for the second half of 2024 to optimize the efficacy and tolerability of GSBR-1290 in this patient population. The ongoing formulation bridging and titration optimization study is evaluating capsule versus tablet pharmacokinetics (PK) and exploring different titration regimens. This study has completed enrollment (n=54), and data are expected in the second quarter of 2024. Pending supportive data from this bridging study, the tablet formulation would be used in future GSBR-1290 studies starting with the Phase 2b studies.
