Novo Nordisk’s next‑generation combination therapy, CagriSema, demonstrated superior efficacy over semaglutide in the 68‑week REIMAGINE 2 phase‑3 trial for type‑2 diabetes. In 2,728 patients, the 2.4 mg/2.4 mg dose lowered HbA1c by 1.91 percentage points versus 1.76 for semaglutide, and produced a 14.2% weight loss compared with 10.2% for the comparator.
The superior outcomes stem from CagriSema’s dual GLP‑1 and amylin agonist mechanism, which simultaneously enhances insulin secretion, suppresses glucagon, and reduces appetite. The additive pharmacology translates into a larger glucose‑lowering effect and greater weight reduction than either agent alone, explaining the 0.15‑point HbA1c advantage and 4‑point percentage‑point weight‑loss advantage observed in the trial.
These results strengthen Novo Nordisk’s competitive position in the rapidly expanding GLP‑1 and obesity markets. By offering a first‑in‑class combination that addresses both glycemic control and weight loss, the company can capture patients who require dual benefits, potentially increasing market share against rivals such as Eli Lilly’s tirzepatide, which is currently in a head‑to‑head study with CagriSema.
Regulatory progress is already underway: Novo submitted weight‑management data to the U.S. FDA in December 2025, and the agency is expected to review the application in 2026. A U.S. approval could lead to a launch as early as late 2026, with a broader 2027 launch timeline for other markets. The company’s strategy to submit data to European regulators in the coming months further supports a global rollout.
Executive Vice President, Chief Scientific Officer and Head of Research and Development Martin Holst Lange said, “By combining semaglutide and cagrilintide, we’re seeing superior outcomes in both blood glucose control and weight reduction beyond what each therapy achieves alone. These results reinforce our belief that CagriSema could be the first amylin‑based combination therapy and a promising treatment option for individuals with type‑2 diabetes who also need weight loss.” The company’s leadership views the trial as a pivotal milestone in its metabolic disease pipeline and signals confidence in the drug’s commercial potential.
Prior to REIMAGINE 2, CagriSema had not met Novo’s internal 25% weight‑loss benchmark in earlier obesity studies, but the current data confirm the efficacy seen in earlier trials and validate the dual‑agonist strategy. The trial’s success also positions Novo to respond to the growing demand for integrated diabetes‑obesity therapies and to maintain its leadership in the GLP‑1 space.
