What is the purpose of this trial?

This trial tests the effectiveness and safety of a new pill, orforglipron, for individuals with obesity or those who are overweight with related health issues. The researchers aim to determine if this pill aids in weight loss and improves conditions such as high blood pressure or sleep apnea. Participants will receive varying doses of orforglipron or a placebo for comparison. Individuals who have struggled with weight loss and have conditions like high blood pressure or sleep apnea might be suitable candidates. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to a potentially groundbreaking treatment.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It might be best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that orforglipron is generally well-tolerated. Research indicates that most people taking orforglipron experience only mild side effects, such as nausea or diarrhea, which are common with weight loss treatments. Orforglipron has also been tested for other conditions, like type 2 diabetes, and proved to be safe. Since this study is in a later phase, there is already some evidence that orforglipron is safe for humans. However, as with any treatment, discussing potential risks with a healthcare provider is important. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for obesity?

Researchers are excited about Orforglipron for obesity because it introduces a new approach to weight management with an oral administration method. Unlike many existing obesity treatments that require injections, Orforglipron is taken as a pill, which could make it more convenient and accessible for patients. Additionally, Orforglipron acts as a GLP-1 receptor agonist, which is a mechanism that helps regulate appetite and food intake, potentially offering a different pathway to effective weight loss compared to traditional options. This unique combination of oral delivery and its specific mechanism of action is why there's a lot of interest in its potential benefits.

What evidence suggests that orforglipron might be an effective treatment for obesity?

Studies have shown that orforglipron can help people with obesity lose weight. In earlier research, participants taking orforglipron lost up to 5.4 kg (about 12 pounds) in just four weeks. Another study found that after 72 weeks, people taking orforglipron lost about 12.4% of their body weight. These results suggest that orforglipron is quite effective for weight loss. It works by affecting hormones that control hunger and blood sugar, helping people eat less and lose weight. Participants in this trial will receive different doses of orforglipron or a placebo to evaluate its effectiveness further. ^{2 4 6 7 8}

Published Research Related to This Trial

A study involving adults with obesity demonstrated that the daily oral GLP-1 receptor agonist orforglipron effectively aids in weight loss, showcasing its potential as a treatment option for obesity.

The findings suggest that orforglipron may offer a convenient oral alternative to traditional injectable GLP-1 receptor agonists, enhancing patient adherence to obesity management.

In obesity or overweight without diabetes, orforglipron increased weight loss at 26 wk. Lau, D.[2023]

In a 12-week study involving 72 adults with type 2 diabetes, the multi-receptor agonist LY3437943 demonstrated a good safety profile, with gastrointestinal disorders being the most common side effects.

LY3437943 significantly reduced daily plasma glucose and HbA1c levels, as well as body weight, in a dose-dependent manner, supporting its potential for once-weekly dosing and further development in treating type 2 diabetes and obesity.

In a 26-week phase 2 trial involving 383 participants with type 2 diabetes, orforglipron significantly reduced HbA1c levels by up to -2.10% compared to placebo and showed greater weight loss of up to -10.1 kg, indicating its efficacy as a treatment option.

The safety profile of orforglipron was comparable to other GLP-1 receptor agonists, with most adverse events being mild to moderate gastrointestinal issues, suggesting it may be a safer and more convenient alternative to injectable treatments.

Efficacy and safety of oral orforglipron in patients with type 2 diabetes: a multicentre, randomised, dose-response, phase 2 study. Frias, JP., Hsia, S., Eyde, S., et al.[2023]

In a phase 2 trial involving 272 adults with obesity, the oral GLP-1 receptor agonist orforglipron resulted in significant weight loss, with participants losing between 8.6% to 14.7% of their body weight by week 36, compared to only 2.3% in the placebo group.

Orforglipron was generally well-tolerated, with mild to moderate gastrointestinal side effects being the most common adverse events, leading to discontinuation in 10-17% of participants, similar to the safety profile of injectable GLP-1 receptor agonists.

In a Phase 1b trial involving 68 participants with type 2 diabetes, orforglipron (LY3502970) demonstrated significant reductions in HbA1c levels (by -1.5% to -1.8%) and body weight (by -0.24 to -5.8 kg) compared to placebo, which only showed a -0.4% change in HbA1c.

Orforglipron was generally well tolerated, with gastrointestinal side effects similar to those seen with other GLP-1 receptor agonists, suggesting it may be a safe and effective oral alternative to injectable treatments.
