The world of pharmacotherapy for obesity is entering a new era, with innovative approaches emerging from research hubs such as Denmark. As detailed in a recent publication, the biopharma company Antag is making impressive strides in the development of a next-generation obesity drug, founded on cutting-edge research from the University of Copenhagen.

Overview of Antag’s Development

Antag has secured €80 million in Series A financing to further its lead program based on the inhibition of the GIP receptor (GIPR). Led by Professors Jens Juul Holst and Mette Rosenkilde, this research is significant because GIPR antagonism could potentially address some of the limitations currently faced by existing therapies. GIP, along with GLP-1, is an incretin hormone that plays a role in insulin secretion after food intake.

The Obesity Drug Pipeline

Antag's flagship candidate, AT-7687, is an injectable peptide treatment designed to enhance weight loss and improve metabolic outcomes through a once-weekly administration. It targets the receptor responsible for regulating body weight, aiming to deliver superior tolerability and effectiveness than existing therapies. The company presents AT-7687 as an attractive alternative to traditional therapies, especially when co-administered with GLP-1 receptor agonists like semaglutide.

Clinical Development and Efficacy

According to Antag, preclinical studies conducted in non-human primates have yielded promising results:

Parameter Outcome
Weight Loss Best-in-industry outcomes with no gastrointestinal side effects.
Glycemic Control Improved glycemic profiles observed.
Lipid Profiles Enhanced lipid profiles noted.

Antag's Future Prospects

With the recent acceptance of its Investigational New Drug (IND) application by the US FDA, Antag is gearing up for Phase 1 clinical trials, slated to begin in 2025. These trials will assess AT-7687 both as a standalone treatment and in combination with GLP-1 receptor agonists.

Investor Insight

The funding round attracted significant attention, led by Versant Ventures and supported by a range of investors including Novo Holdings and SR One. Dr. Alex Mayweg of Versant noted:

“Antag’s peptides will have important advantages given their ability to be used alone or optimally combined with other incretin-based agents.”

Conclusion

As the landscape of obesity treatment evolves, Antag's innovative approach in targeting GIPR highlights the potential for enhanced therapies that address common limitations associated with existing obesity drugs. The journey ahead promises a blend of scientific investments and groundbreaking discoveries in the obesity treatment sector.
