Novo says CagriSema shows greater weight loss than Lilly rival in diabetes patients

Sept 21 (Reuters) – Novo Nordisk said on Monday its next-generation experimental drug, CagriSema, delivered an estimated average weight loss of 12.4% in a late-stage trial in patients with ​diabetes, outperforming Eli Lilly’s rival drug.

It has been viewed ‌as a successor to Novo’s blockbuster weight-loss drug, Wegovy, which faces patent expiries after 2030, and could help the Danish drugmaker claw back ground lost to Lilly in the fast-growing weight-loss market.

In a head-to-head trial earlier this year, ‌the ​drug fell short of Lilly’s Zepbound on ⁠weight loss, marking a ⁠setback for Novo.

CagriSema is a weekly injection that combines cagrilintide, which mimics pancreatic hormone amylin, and semaglutide, the active ingredient in Wegovy.

At Novo’s capital markets day on Monday, the company detailed ​a multi-year rollout for its next-generation obesity injectables, targeting a launch of its CagriSema combination early next year.

Novo’s U.S.-listed shares were ⁠down more than 4% before the ⁠bell as analysts questioned the drugmaker’s pricing power ​and dealmaking strategy ahead of looming patent expiries.

In the late-stage study, ​a 1 mg dose of Novo’s drug CagriSema was superior ‌to Lilly’s tirzepatide at 5 mg for weight loss, the company said on Monday. Lilly’s tirzepatide, the active ingredient in its diabetes drug Mounjaro and obesity drug Zepbound, showed a weight loss ⁠of 9.1%.

While the low-dose data is encouraging, the findings were less impactful given tirzepatide has already been proven superior to higher doses of Novo’s ⁠CagriSema in obesity, ‌said BMO analyst Evan Seigerman.

In patients with diabetes, ⁠Novo’s drug also showed demonstrated non-inferior blood sugar ​reduction ‌compared to Lilly’s tirzepatide.

In another late-stage study, the ​drug showed ⁠a 21% weight loss at a 1.0 mg dose compared to placebo in adults with obesity.

A decision from the U.S. Food and Drug Administration on the company’s application for CagriSema for weight management is expected in the fourth quarter.
