SAN FRANCISCO, Aug. 06, 2026 (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 second quarter ended June 30, 2026 and provided a business update including the initiation of the Phase 3 ACCOMPLISH program evaluating aleniglipron for chronic weight management.

“Dosing the first patients in ACCOMPLISH-1 and -2 is a defining milestone for Structure as we advance aleniglipron, our potentially best-in-class oral GLP-1 receptor agonist, toward potential registration,” said Raymond Stevens, Ph.D., Chief Executive Officer of Structure Therapeutics. “As we enter this next stage of development, the appointment of John Berrios as our Chief Commercial Officer adds tremendous experience in obesity, diabetes, market access and commercialization to our senior leadership team, particularly given his leadership role in the GLP-1 space.”

“Obesity is a chronic disease, and people need treatment options that can adapt to their individual goals over time,” continued Dr. Stevens. “We are building a comprehensive portfolio of oral small molecule medicines designed to provide greater choice, flexibility and accessibility across the treatment journey, from initial weight loss through long-term weight maintenance. As an important component of this strategy, we are advancing ACCG-2671, our potentially first-in-class oral small molecule dual amylin and calcitonin receptor agonist and remain on track to report initial single ascending dose data and initiate a multiple ascending dose clinical trial in the third quarter. We also look forward to initiating our combination GLP-1 and amylin receptor agonist clinical trial later this year. We believe these programs have the potential to provide meaningful, sustained weight and metabolic benefits through convenient and accessible oral treatment options.”

Recent and Upcoming Milestones

Aleniglipron – Oral Small Molecule Selective Glucagon-Like Peptide 1 (GLP-1) Receptor Agonist for Chronic Weight Management

The Company announced that the first patients have been dosed in the Phase 3 ACCOMPLISH program, which includes two clinical trials evaluating aleniglipron, a once-daily oral small molecule GLP-1 receptor agonist.

• ACCOMPLISH-1 is evaluating aleniglipron in adults living with obesity or overweight with a weight-related comorbidity and will enroll up to 3,600 patients; ACCOMPLISH-2 is evaluating aleniglipron in adults living with obesity or overweight and type 2 diabetes mellitus (T2DM) and will enroll up to 1,100 patients.
• ACCOMPLISH-1 and ACCOMPLISH-2 are randomized, double-blind, placebo-controlled clinical trials designed to evaluate the long-term efficacy and safety of three maintenance doses of aleniglipron. Participants in the clinical trials will be randomized to one of four treatment arms, with three active doses (45 mg, 90 mg or 180 mg) or placebo. Patients will begin treatment at a 2.5 mg starting dose with 4-week titration increments.
• Together, the ACCOMPLISH clinical trials are designed to support global regulatory submissions for aleniglipron in chronic weight management.
• Additional information about ACCOMPLISH-1 and ACCOMPLISH-2, including endpoints, eligibility criteria and enrolling sites, is available at ClinicalTrials.gov under identifiers NCT07654361 and NCT07654374, respectively.
  
  

In June 2026, data from the Phase 2b ACCESS clinical trial of aleniglipron were published in Nature Medicine and highlighted in an oral presentation at the American Diabetes Association's (ADA) 86th Scientific Sessions. The publication and presentation detailed dose-dependent, clinically meaningful and statistically significant reductions in body weight, with continued weight loss beyond 36 weeks and up to 16.2% at 44 weeks observed during the open-label extension. The tolerability profile reflected the well-known gastrointestinal-related adverse events typical of the GLP-1 class, with a favorable overall discontinuation rate of 10.4%.

Structure plans to report new data from the following aleniglipron clinical trials in the second half of 2026:

• The ACCESS Open Label Extension (OLE) clinical trial is evaluating the tolerability of the dose titration regimen that includes a starting dose of 2.5 mg in placebo crossover patients. The clinical trial will be completed after a total of 72 weeks of treatment, where some participants have been exposed to 180 mg for a certain period of time. Data are expected in Q3 2026.
• The Body Composition clinical trial is assessing the effect of aleniglipron on body fat loss over a 44-week evaluation period. Data are expected in Q4 2026.
• The clinical trial in patients with T2DM with obesity/overweight is evaluating the potential for including participants with T2DM in the Phase 3 program. Data are expected in Q4 2026.
• The SWITCH clinical trial is assessing the transition from an approved injectable GLP-1 receptor agonist to once-daily oral aleniglipron for long-term weight loss maintenance. Data are expected in Q4 2026.
  
  

Oral Small Molecule Dual Amylin and Calcitonin Receptor Agonists

• ACCG-2671, an oral small molecule dual amylin and calcitonin receptor agonist, continues to be evaluated in an ongoing Phase 1 single ascending dose (SAD) clinical trial assessing safety, tolerability, pharmacokinetics and food effect in healthy adult participants. Initial data, along with initiation of a multiple ascending dose (MAD) clinical trial, remain on track for Q3 2026.
• The Company plans to initiate a Phase 1 clinical trial of its second oral small molecule dual amylin and calcitonin receptor agonist candidate, ACCG-3535, in Q4 2026, demonstrating continued leadership in the oral small molecule amylin field.
  
  

Combination of Oral Small Molecule GLP-1 and Amylin Receptor Agonists

• Preclinical combination data of aleniglipron and ACCG-2671 were presented at the ADA Scientific Sessions in June 2026 demonstrating additional weight loss compared to each monotherapy in non-human primates. A combination clinical trial is expected to be initiated in Q4 2026.
  
  

Appointment of John Berrios as Chief Commercial Officer (CCO)

• Structure has appointed John Berrios as its CCO. Mr. Berrios brings more than 25 years of commercial leadership experience across the biopharmaceutical industry, with expertise spanning commercial strategy, sales, marketing, operations and market access. Most recently, he served as Head of U.S. Sales Strategy and Innovation for Obesity and Diabetes at Novo Nordisk and was instrumental in leading the strategic planning and commercial launch of its obesity and diabetes portfolio. Previously, he held senior leadership roles at Bayer Pharmaceuticals and AstraZeneca, where he led commercial organizations and supported the launch and growth of multiple products across obesity, diabetes, cardiovascular disease, and other therapeutic areas.
  
  

Second Quarter 2026 Financial Highlights

Cash Position: Cash, cash equivalents and short-term investments totaled $1.3 billion as of June 30, 2026, compared to $1.5 billion as of March 31, 2026. The Company expects its current cash, cash equivalents and short-term investments to fund projected operations and key clinical milestones through the end of 2028, including costs related to the ongoing aleniglipron ACCESS OLE, ACCESS II extension clinical trial, the supplementary clinical trials, and Phase 3 registrational program in chronic weight management, but excludes additional costs related to pre-commercialization activities including commercial manufacturing.

Research and Development (R&D) Expenses: R&D expenses for the second quarter of 2026 were $100.1 million, as compared to $54.7 million for the same period in 2025. The increase in research and development 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).

General and Administrative (G&A) Expenses: G&A expenses for the second quarter of 2026 were $18.6 million, as compared to $15.7 million for the same period in 2025. The increase in G&A expenses was primarily due to increases in employee expenses as the Company expanded its infrastructure to drive and support the growth in operations as a publicly-traded company, and increases in professional services.

Net Loss: Net loss for the second quarter of 2026 totaled $106.2 million, with non-cash share-based compensation expense of $12.6 million, compared to a net loss of $61.7 million for the same period in 2025, with non-cash share-based compensation expense of $7.5 million.
