A groundbreaking clinical trial has revealed that orforglipron, a novel oral medication, may offer a more effective option for weight loss compared to existing treatments. Currently undergoing regulatory review, this potential game-changer for patients with type 2 diabetes could reshape how obesity is managed, especially for those who prefer non-injection alternatives.
A New Contender in Weight Loss Medication
Developed by Eli Lilly, orforglipron operates on the same GLP-1 receptors as the well-known oral medication semaglutide. While both drugs aim to lower blood sugar levels and suppress appetite, orforglipron has the added benefit of not requiring patients to take it on an empty stomach. This feature, along with its promising results, positions orforglipron as a significant advancement in the realm of weight-loss medications.
Although orforglipron has not yet received approval from regulatory authorities in the UK, US, or Europe, the US Food and Drug Administration (FDA) is currently reviewing its application. This scrutiny comes at a time when semaglutide is the only GLP-1 medication available in pill form for diabetes management in the US.
Clinical Trial Insights
The Achieve-3 trial, a comprehensive phase 3 study sponsored by Eli Lilly, involved over 1,500 adults diagnosed with type 2 diabetes across 131 medical research facilities globally, including locations in Argentina, China, Japan, Mexico, and the United States. Participants were administered varying doses of orforglipron (12mg or 36mg) or oral semaglutide (7mg or 14mg) over a year-long period.

Results indicated that those taking orforglipron experienced an average weight loss of 6-8% of their body weight, significantly outperforming the 4-5% weight reduction noted among semaglutide users. Additionally, participants taking orforglipron recorded lower blood sugar levels by the trial’s conclusion.
However, it is worth noting that the discontinuation rates were higher among those using orforglipron, with 9-10% of participants ceasing treatment due to side effects, predominantly gastrointestinal issues. In comparison, 4-5% of semaglutide participants reported similar experiences.
Expert Opinions on Findings
Tam Fry, Chair of the National Obesity Forum, expressed optimism about orforglipron’s potential: “It could emerge as the preferred treatment for those struggling with obesity and diabetes. Its straightforward usage is a real advantage. However, once it hits the market, its distribution must be carefully controlled to prevent misuse, as seen with semaglutide.”
Dr Marie Spreckley from the MRC Epidemiology Unit at the University of Cambridge cautioned against over-enthusiasm. “While the findings are encouraging, the higher rate of discontinuation due to adverse effects must be carefully considered. Long-term safety, cardiovascular outcomes, and sustained effectiveness remain critical areas for further investigation,” she noted.
Professor Naveed Sattar from the University of Glasgow reinforced the significance of these results, stating, “The availability of more effective oral medications for weight loss in diabetes management is crucial. A holistic approach that addresses weight, blood sugar, and cardiovascular health simultaneously is likely to yield the best outcomes for patients.”
Why it Matters
The development of orforglipron could signify a pivotal moment in the management of obesity and type 2 diabetes, particularly for individuals who prefer oral medications over injections. As healthcare systems globally grapple with rising obesity rates and associated health complications, innovative treatments like orforglipron could not only enhance patient adherence but also improve overall health outcomes. By making weight management more accessible and effective, orforglipron has the potential to transform the lives of millions struggling with diabetes and obesity, paving the way for a healthier future.
