Indianapolis, Indiana – August 22, 2025 – Researchers have announced encouraging findings from a late-stage clinical trial evaluating Orforglipron, a novel oral medication designed to aid in Weight Loss. The results, unveiled Today, suggest that the drug coudl offer a significant new option for individuals struggling with Obesity or being overweight with related health issues.

The Growing Crisis of Obesity

Obesity rates continue to climb globally, creating a major public health challenge. According to the Centers for Disease Control and Prevention, over 40% of adults in the United States were classified as obese as of 2022. This condition significantly elevates the risk of serious health problems, including Cardiac Disease, Type 2 Diabetes, and Stroke.

“Obesity is a complex disease impacting a substantial portion of the global population,” stated Dr. Amelia Hayes, a leading Endocrinologist not associated with the study. “New treatment options, especially those that are more accessible like an oral medication, are critically needed.”

Understanding Orforglipron and its Mechanism

Orforglipron is a once-daily oral glucagon-like-peptide-1 receptor agonist (GLP-1 RA). This class of drugs works by mimicking the effects of a natural hormone that regulates Appetite and Blood Sugar levels. By stimulating Insulin release and slowing down the rate at which food exits the stomach, Orforglipron helps individuals feel fuller for longer, ultimately leading to reduced Calorie intake.

Key Findings from the ATTAIN-1 Trial

The ATTAIN-1 trial, a randomized, double-blind, placebo-controlled study, involved over 3100 participants with Obesity or overweight and comorbidities, such as High Blood Pressure or Cardiovascular Disease. Participants were assigned to receive either 6 mg, 12 mg, or 36 mg of Orforglipron, or a Placebo, over a 72-week period.

The studyS primary goal was to assess the drug’s effectiveness in promoting Weight Loss.The results demonstrated that participants receiving the highest dose of Orforglipron (36 mg) experienced an average Weight reduction of 27.3 pounds. Notably, over half (59.6%) of those on the highest dose lost at least 10% of their body Weight,and nearly 40% (39.6%) achieved a 15% reduction.

Beyond Weight Loss, the trial also indicated positive effects on Cardiovascular risk factors. All three doses of Orforglipron were associated with reductions in non-HDL Cholesterol,Triglycerides,and Systolic Blood Pressure.

Dose (mg) Average Weight Loss (lbs) % Losing ≥10% Body Weight % Losing ≥15% Body Weight
6 17.1 35.2 18.7
12 22.5 48.3 28.1
36 27.3 59.6 39.6
Placebo 2.2 8.1 3.2

Did You Know? GLP-1 receptor agonists have traditionally been administered via injection. Orforglipron’s oral form could significantly improve patient compliance and accessibility.

The most commonly reported side effects were mild to moderate Gastrointestinal issues,including Nausea,Constipation,and Diarrhea. While Discontinuation rates due to adverse events were higher with Orforglipron compared to Placebo, the overall number of participants who left the study for any reason was lower in the Orforglipron groups.

What’s Next for Orforglipron?

“Thes findings represent a potential paradigm shift in how we approach Obesity treatment,” stated Kenneth Custer, PhD, Executive Vice President of Lilly Cardiometabolic Health. “We are preparing to submit Orforglipron for regulatory review and anticipate a global launch if approved, addressing a critical and growing public health need.”

Pro Tip: Combining medication with lifestyle modifications – a healthy diet and regular exercise – maximizes weight loss outcomes and improves overall health.

What impact do you think oral Weightloss medications will have on future Obesity treatment? Will they improve compliance and accessibility for patients?
