Structure Therapeutics’ GSBR-1290: The Oral GLP-1 Pill Seeks to Transform Obesity Treatment

The landscape of obesity and diabetes treatment is evolving, with GLP-1 medications playing a pivotal role. Structure Therapeutics has initiated dosing in their Phase 2b ACCESS study for GSBR-1290, an oral GLP-1 receptor agonist targeting individuals with obesity or weight-related comorbidities. This development underscores the potential of oral GLP-1 options like GSBR-1290 to offer significant advantages over injectables, particularly in terms of convenience and accessibility.


The Significance of Oral GLP-1 Options

Injectable GLP-1 medications have demonstrated efficacy in managing weight and blood sugar levels but come with challenges such as storage requirements, transportation logistics, and the need for injections. Oral GLP-1 medications, like GSBR-1290, aim to simplify treatment by eliminating the need for injections, thereby enhancing patient adherence and broadening accessibility.


Small Molecules vs. Peptides: Enhancing Bioavailability

A notable feature of GSBR-1290 is its design as a small molecule. Unlike peptide-based drugs, which are often degraded in the digestive system and thus require injection, small molecules are more bioavailable, meaning they are more readily absorbed into the bloodstream when taken orally. This characteristic not only facilitates oral administration but also offers manufacturing scalability advantages, potentially reducing costs and improving patient access.


The ACCESS and ACCESS II Studies: GSBR-1290’s Development Path

The ACCESS study is evaluating multiple doses of GSBR-1290 over 36 weeks, employing a gradual titration approach to optimize tolerability. Doses up to 120 mg are being tested, with primary endpoints focusing on weight reduction, safety, and tolerability. In parallel, the ACCESS II study is assessing higher doses, up to 240 mg, to determine if increased efficacy can be achieved. Results from these studies are anticipated in late 2025, which will inform the progression to Phase 3 trials.


GSBR-1290 Among Other Oral GLP-1 Candidates

GSBR-1290 is part of a broader movement toward small molecule oral GLP-1 therapies. Eli Lilly's orforglipron, expected in 2026, is another small molecule GLP-1 receptor agonist showing promise in clinical studies. Pfizer is developing danuglipron, a once-daily small molecule oral GLP-1 receptor agonist, advancing its development based on recent pharmacokinetic studies. Roche has introduced CT-966, a small molecule oral GLP-1 receptor agonist that demonstrated a 7.3% weight loss over four weeks in a Phase 1 trial.


In addition to small molecules, peptide-based oral formulations are also in development. Notably, Novo Nordisk is working on a high-dose (25 mg) oral semaglutide, with potential availability in 2025. Viking Therapeutics is exploring an oral version of VK2735, currently in early-phase trials, with potential availability in the coming years.


Looking Ahead: The Promise of Oral GLP-1 Medications

The development of oral GLP-1 medications represents a significant advancement in obesity and diabetes treatment, offering the potential for improved patient adherence and broader accessibility. Medications like GSBR-1290 could eliminate barriers associated with injectable forms, providing a more convenient option for patients.


As the field progresses, staying informed about these developments is crucial. Sharing this information within healthcare communities can support greater awareness and access to emerging therapies, ultimately enhancing patient care.
