Bagsværd, Denmark- December 2024- Novo Nordisk announced headline results from REDEFINE 1, a phase 3 trial in the global REDEFINE programme. REDEFINE 1 is a 68-week efficacy and safety trial investigating subcutaneous CagriSema (a fixed dose combination of cagrilintide 2.4 mg and semaglutide 2.4 mg) compared to the individual components cagrilintide 2.4 mg, semaglutide 2.4 mg and placebo, all administered once-weekly. The trial included 3,417 randomised people with obesity or overweight with one or more comorbidities and a mean baseline body weight of 106.9 kg.

The trial achieved its primary endpoint by demonstrating a statistically significant and superior weight loss at week 68 with CagriSema versus placebo.

The REDEFINE 1 trial was based on a flexible protocol, allowing patients to modify their dosing throughout the trial. After 68 weeks, 57.3% of patients treated with CagriSema were on the highest dose compared to 82.5% with cagrilintide 2.4 mg and 70.2% with semaglutide 2.4 mg.

When evaluating the effects of treatment if all people adhered to treatment, people treated with CagriSema achieved a superior weight loss of 22.7% after 68 weeks compared to a reduction of 11.8% with cagrilintide 2.4 mg, 16.1% with semaglutide 2.4 mg and 2.3% with placebo alone. In addition, 40.4% of patients who received CagriSema reached a weight loss of 25% or more after 68 weeks, compared to 6.0% with cagrilintide 2.4 mg, 16.2% with semaglutide 2.4 mg, and 0.9% with placebo.

When applying the treatment policy estimand, people treated with CagriSema achieved a superior weight loss of 20.4% compared to a reduction of 11.5% with cagrilintide 2.4 mg, 14.9% with semaglutide 2.4 mg and 3.0% with placebo.

In the trial, CagriSema, cagrilintide 2.4 mg and semaglutide 2.4 mg appeared to have a safe and well-tolerated profile. The most common adverse events with CagriSema were gastrointestinal, and the vast majority were mild to moderate and diminished over time, consistent with the GLP-1 receptor agonist class.

“We are encouraged by the weight loss profile of CagriSema demonstrating superiority over both semaglutide and cagrilintide in monotherapy in the REDEFINE 1 trial. This was achieved even though only 57% of patients reached the highest CagriSema dose,” said Martin Holst Lange, executive vice president for Development at Novo Nordisk.
