***ACCESS II Study - Evaluating higher doses up to 240 mg***

ACCESS II is a randomized, double-blind, placebo-controlled, clinical study of aleniglipron that enrolled 85 adult participants living with obesity or overweight (defined as a BMI of greater than 25 kg/m2) with at least one weight-related comorbidity. The 44-week 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.

As reported in December 2025, at 36 weeks, each of the three dose cohorts in the ACCESS II study met statistical significance compared to placebo. Results from the primary efficacy estimand<sup>i</sup> at 44 weeks are as follows:

|:---|:---|:---|:---|:---|
|  | &nbsp;&nbsp; **Aleniglipron**<br> **120 mg** | &nbsp;&nbsp; **Aleniglipron**<br> **180 mg** | &nbsp;&nbsp; **Aleniglipron**<br> **240 mg** | &nbsp;&nbsp;**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 GLP-1 receptor agonist drug class, the most common AEs were gastrointestinal (GI)-related, and the two most common AEs in the titration phase were nausea and vomiting.

<sup>i</sup> The primary efficacy estimand represents efficacy had all randomized participants remained on study treatment (with possible dose interruptions and/or dose modifications) for 44 weeks without initiating rescue weight management treatments or surgeries.

 ****

***Body Composition Study - Evaluating lower 2.5 mg starting dose***

Structure Therapeutics is 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 of 20 weeks demonstrated that starting at a lower dose of 2.5 mg for the first four weeks supported a manageable tolerability profile with meaningful improvements in AE-related discontinuations compared to what was observed at a starting titration dose of 5 mg in the ACCESS and ACCESS II studies. Additionally, at a 2.5 mg start and after a median follow up of 20 weeks (~ 30 mg titration step) aleniglipron showed a 6.8% weight loss.

***ACCESS Open-Label Extension Study - Following randomized 36-week period, evaluating lower 2.5mg starting dose in the placebo crossover arm and efficacy beyond 36 weeks in previously treated participants***

 ****

Following the 36-week randomized controlled portion of the Phase 2b ACCESS study, participants were provided an option to roll over into the OLE and receive aleniglipron for an additional 36 weeks. A pre-specified interim analysis after a median follow-up of 20 weeks (a total of 56 weeks) demonstrated continuing weight loss in all dose cohorts, with no evidence of weight loss plateau. Patients who received aleniglipron in the three active dose arms during the initial double-blind portion were titrated to a maximum dose of 120mg during the OLE. These patients achieved continued weight loss of up to 16.2% from baseline out to 56 weeks.

Participants who received placebo in the initial double-blind portion transitioned to aleniglipron at a starting dose of 2.5 mg and titrated monthly to a target dose of 120 mg. Initial data from this group of participants after a median follow-up of 20 weeks are consistent with the findings from the body composition study, showing that starting at a 2.5 mg and titrating slowly was associated with a meaningful improvement in key tolerability markers compared to what was observed in the starting 5 mg titration dose in ACCESS and ACCESS II studies.

**Aleniglipron Safety**

Aleniglipron demonstrated a compelling safety profile in more than 625 participants across all studies. Importantly, to date, there have been 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 continue to provide a strong foundation to advance aleniglipron into Phase 3 clinical development. The Company has a Type B End-of-Phase 2 meeting with the United States Food and Drug Administration (FDA) scheduled in the second quarter 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 in the second half of 2026.

**Forward-Looking Statements** 

This Current Report on Form 8-K contains "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995.

**SAN FRANCISCO, March 16, 2026–** 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 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 44-week data from the Phase 2 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 Phase 2 ACCESS II study, aleniglipron achieved clinically meaningful and statistically significant placebo-adjusted mean weight loss of 16.3% (39 lbs; p<0.0001) at the 180 mg dose and 16.0% (37 lbs; p<0.0001) at the 240 mg dose at 44 weeks. In the ACCESS OLE study, aleniglipron achieved continued weight loss from 36 weeks, up to 16.2% (40.5 lbs) with 120 mg at 56 weeks. Both studies continue to demonstrate no evidence of weight loss plateau.

Aleniglipron continues to demonstrate a tolerability profile that is consistent with the GLP-1 receptor agonist class and a compelling safety profile with no off-target events. In ACCESS II, across all active arms in participants who reached doses 120 mg or higher from 28 to 44 weeks, there was only one (3.7%) adverse event (AE)-related treatment discontinuation.

With a median follow-up of 20 weeks, the tolerability data as of the February 20, 2026 cutoff date from the interim analyses of the OLE and the body composition studies provide further support that the use of 2.5 mg as a lower starting dose very meaningfully reduces the rate of AE-related discontinuations during the titration phase. In the OLE, with a median follow-up of 20 weeks, there was an overall AE-related discontinuation rate of 2%. In the body composition study, with a median follow-up of 20 weeks, there was an overall AE-related discontinuation rate of 3.4% in the aleniglipron arm.

Together, these positive efficacy, tolerability and safety findings continue to support the advancement of aleniglipron into Phase 3 clinical development, with initiation anticipated in the second half of 2026.

"The totality of efficacy and tolerability data across the Phase 2 program continue to demonstrate clear differentiation of aleniglipron, with the highest weight loss observed for an oral GLP-1RA to date and a safety profile appropriate for chronic use in a disease that impacts millions of people," said Raymond Stevens, Ph.D., CEO of Structure Therapeutics. "The consistent weight loss observed across multiple studies to date reaffirms aleniglipron's potential to be a best-in-class oral GLP-1, with injectable-like efficacy that could become a backbone oral small molecule therapy for obesity."

"The weight-lowering data from these ACCESS studies, without apparent plateau by Week 56, are encouraging—particularly the weight loss from baseline of up to -15.3% vs +1.1% at 180 mg in ACCESS II that hopefully will be confirmed in larger, longer-term studies," said Julio Rosenstock, MD, Chair of the ACCESS program Steering Committee and Clinical Professor of Medicine, Univ. of Texas, Southwestern Medical Center. "In addition, the tolerability profile of starting at a low dose of 2.5 mg and the slow titration, positions the program ready for Phase 3 studies."

***ACCESS II Study - Evaluating higher doses up to 240 mg***

ACCESS II is a randomized, double-blind, placebo-controlled, clinical study of aleniglipron that enrolled 85 adult participants living with obesity or overweight (defined as a BMI of greater than 25 kg/m2) with at least one weight-related comorbidity. The 44-week 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.

As reported in December 2025, at 36 weeks, each of the three dose cohorts in the ACCESS II study met statistical significance compared to placebo. Results from the primary efficacy estimand<sup>i</sup> at 44 weeks are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | &nbsp;&nbsp; **Aleniglipron**<br> **120 mg** | &nbsp;&nbsp; **Aleniglipron**<br> **180 mg** | &nbsp;&nbsp; **Aleniglipron**<br> **240 mg** | &nbsp;&nbsp;**Placebo** |
