A Phase III, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study to Evaluate the Efficacy and Safety of Once-Weekly RO7795068 Administered to Participants With Obesity or Overweight and Type 2 Diabetes

Hoffmann-La Roche

RO7795068, a dual GLP-1/GIP receptor agonist from Roche, is being tested versus placebo for weight management in people with obesity or overweight and type 2 diabetes. Phase 3 trial targets 1,600 participants over 72 weeks in a randomized, double-blind, placebo-controlled design. This positions Roche to compete directly with Eli Lilly's tirzepatide (Mounjaro/Zepbound) in the dual incretin mechanism space across both diabetes and obesity indications. The trial represents Roche's first major entry into the competitive GLP-1 obesity market dominated by Novo Nordisk and Eli Lilly.

Strategic signal

Roche enters the dual GLP-1/GIP mechanism that Eli Lilly has dominated with tirzepatide since 2022, potentially creating pricing pressure and formulary competition in both diabetes and obesity markets. US payers who have restricted tirzepatide access due to cost may welcome a second dual incretin option to drive rebate negotiations. However, Roche faces a 6-year delay versus tirzepatide's established efficacy profile and market penetration, requiring superior efficacy data or differentiated safety to gain meaningful share.

Original Abstract

The purpose of this study is to assess the efficacy and safety of RO7795068, a dual glucagon-like peptide-1 (GLP-1)/glucose-dependent insulinotropic polypeptide (GIP) receptor agonist (RA), at multiple doses compared with placebo for weight management in participants with obesity or overweight and Type 2 diabetes mellitus (T2DM). | Condition(s): Obesity or Overweight; Type 2 Diabetes Mellitus | Primary endpoint(s): Percent (%) Change from Baseline in Body Weight at Week 72 | Enrollment: 1,600 (estimated) | Phase: Phase 3 | Sponsor: Hoffmann-La Roche | Expected completion: 2028-08-07 | Status: Recruiting | Last update: 2026-04-14

FDA Approves Foundayo (Orforglipron) — New Drug Approval (NDA/BLA)

FDA approved orforglipron (Foundayo, Eli Lilly) for type 2 diabetes -- a once-daily oral small-molecule GLP-1 receptor agonist. Orforglipron is the first non-peptide oral GLP-1 approved in the US; oral semaglutide (Rybelsus, Novo Nordisk) has been approved for T2D since 2019 and expanded to obesity in January 2026. Unlike Rybelsus, orforglipron requires no fasting or water volume restrictions before dosing.

Efficacy and Safety of Tirzepatide Once Weekly in Participants Without Type 2 Diabetes Who Have Obesity or Are Overweight With Weight-Related Comorbidities: A Randomized, Double-Blind, Placebo-Controlled Trial (SURMOUNT-1)

Phase 3 SURMOUNT-1 tests once-weekly tirzepatide at three doses versus placebo in adults without type 2 diabetes who have obesity or are overweight with comorbidities. The randomized, double-blind trial targets 2,539 participants with primary efficacy assessment at 72 weeks. This represents tirzepatide's pivotal obesity trial against placebo, potentially supporting Eli Lilly's bid to compete directly with Wegovy in the non-diabetic obesity market. A prediabetes subgroup continues long-term to assess diabetes prevention.

The Effect of Semaglutide in Subjects With Non-cirrhotic Non-alcoholic Steatohepatitis

Phase 3 trial evaluates semaglutide versus placebo in adults with non-cirrhotic NASH, measuring steatohepatitis resolution, fibrosis improvement, and cirrhosis-free survival over approximately 5 years. The study enrolled 1,205 adults and is active but not recruiting, with completion expected in 2029. This represents Novo Nordisk's push into NASH, a major unmet need with no approved GLP-1 therapies despite strong preclinical rationale. The trial's dual primary endpoints and 5-year duration suggest preparation for a pivotal regulatory filing in this large addressable market.

Phase 3 trial evaluating retatrutide for chronic low back pain in people with obesity or overweight, targeting dual primary endpoints of pain intensity reduction and weight loss. 586-person placebo-controlled study expected to complete September 2027, investigating a novel indication beyond traditional metabolic endpoints. Eli Lilly is exploring pain management as a potential expansion for their triple agonist, representing the first major trial of a GLP-1-based therapy specifically for chronic pain conditions.
