Novo Nordisk during the company’s Capital Markets Day event on Thursday unveiled positive Phase I data for its next-generation obesity therapy amycretin, demonstrating an overall favorable safety profile and strong weight-loss signals.

At 12 weeks, study participants who were given the investigational drug saw a 13.1% weight loss, the Danish pharma reported in its R&D presentation at the investor event. The placebo group, on the other hand, saw only a 1.1% reduction in body weight over the same time span.

Amycretin was also safe and well-tolerated overall and its adverse effects were in line with Novo’s prior studies of GLP-1 receptor agonists, the company said. The pharmacokinetic findings in the Phase I study also encourage further assessment of amycretin.

Designed to be orally available, amycretin is a co-agonist of both the GLP-1 and amylin receptors—both of which are involved in regulating appetite and controlling blood glucose levels, though their effects are mediated through complementary pathways. Amylin receptors are located on β-cells in the pancreas, while GLP-1 receptors are concentrated in L-cells in the intestine.

According to Novo’s presentation, amycretin is a unimolecular candidate, meaning that it combines two mechanisms of action in a single molecule and yields additive effects.

Novo is developing amycretin as part of its pipeline in diabetes and obesity, which seeks to maximize its current GLP-1 franchise and leverage other innovative approaches including those that target amylin and GIP receptors. For future projects, Novo will focus on regulating appetite and energy expenditure, maintaining weight, preserving lean mass and evaluating sustained-release modes of delivery.

The pharma is looking to start another amylin program in the coming months, with a Phase I trial slated for 2024. Novo is also gearing up for another Phase I study in the next 12 months for a new tri-agonist candidate, which the company contends has the potential for greater weight loss and other obesity-related comorbidities.

Aside from amycretin and the upcoming Phase I programs, Novo is already targeting the amylin pathway through its late-stage weight-loss combo therapy CagriSema, which combines the top-selling semaglutide—marketed as Ozempic for type 2 diabetes and Wegovy for chronic weight management—with an amylin analog dubbed cagrilintide.

In August 2022, the drugmaker released Phase II data for CagriSema, demonstrating a 15.6% drop in body weight in type 2 diabetes patients who were overweight. This effect was numerically better when compared with cagrilintide or Wegovy alone. In September 2023, Novo launched a Phase III head-to-head trial pitting CagriSema against Eli Lilly’s Zepbound (tirzepatide).

Novo is also seeking to expand its expertise beyond obesity and diabetes, targeting cardiometabolic diseases more broadly.

On Tuesday, the pharma reported that Ozempic induced a 24% reduction in the risk of kidney disease progression, major adverse cardiovascular events and kidney death versus placebo in patients with type 2 diabetes and chronic kidney disease. Novo is eyeing a label expansion for Ozempic, with filings planned for later this year.
