A Master Protocol to Investigate the Efficacy and Safety of Orforglipron Tablet Once Daily Compared With Placebo in Female Participants With Stress Urinary Incontinence Who Have Obesity or Overweight

Eli Lilly and Company

Orforglipron is being tested in women with stress urinary incontinence who have obesity or overweight in two phase 3 studies under a master protocol. The trials will enroll 1,000 participants with 58-week follow-up, comparing daily oral orforglipron to placebo. This represents a novel indication expansion for Eli Lilly's small-molecule GLP-1 beyond diabetes and weight management, targeting a large underserved population where weight loss could provide therapeutic benefit. This marks the first major GLP-1 trial in urological conditions, potentially opening a new market segment.

Strategic signal

Eli Lilly is positioning orforglipron for urological indications before competitors, potentially creating a differentiated commercial narrative beyond metabolic health. This strategy mirrors how SGLT2 inhibitors expanded from diabetes to heart failure and kidney disease, establishing new revenue streams. If successful, this could support premium pricing and formulary positioning by addressing an unmet medical need where existing treatments are limited.

Original Abstract

The GZPS master protocol will support two independent studies, J2A-MC-GZS1 and J2A-MC-GZS2. Each study will see how well and safely orforglipron works in adult female participants with stress urinary incontinence (SUI) who have obesity or overweight. SUI is leaking urine during movement or activity such as coughing or exercising. Participation in the study will last about 58 weeks from screening to safety follow-up. | Condition(s): Urinary Incontinence,Stress | Primary endpoint(s): Change from Baseline in Incontinence Episode Frequency (IEF) | Enrollment: 1,000 (estimated) | Phase: Phase 3 | Sponsor: Eli Lilly and Company | Expected completion: 2028-03 | Status: Recruiting | Last update: 2026-03-20

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.
