Antag Therapeutics, a Copenhagen-based biopharmaceutical innovator, has secured €80 million in a Series A financing round led by Versant Ventures. Novo Holdings, SR One, Dawn Biopharma, Pictet, Longview Ventures, and EIFO also participated. The funds will propel the clinical development of AT-7687, a once-weekly GIPR antagonist peptide aimed at revolutionizing obesity treatment by complementing GLP-1-based therapies. With FDA clearance for Phase I trials, the company plans to test the peptide as a monotherapy and in combination with GLP-1 agonists. The funding will also support pipeline expansion, including monthly injectable therapies, positioning Antag at the forefront of next-generation obesity solutions.
GLP-1-based therapies have revolutionized obesity management, but for some patients can cause tolerability issues, loss of muscle mass, and suboptimal weight-loss. This highlights the need for complementary pharmacological approaches.
The genetic basis for antagonizing GIPR is clear. Individuals with naturally occurring genetic GIPR variants that reduce its activity have lower BMI and body fat percentages, resulting in a leaner phenotype compared to those with normal GIPR function.
The development of Antag’s lead molecule is rooted in the groundbreaking identification of an endogenous GIPR antagonist by University of Copenhagen professors Jens Holst, renowned for his discovery of GLP-1, and Mette Rosenkilde. Both co-founded Antag and bring extensive expertise in incretin biology spanning decades. Professor Holst also chairs Antag’s scientific advisory board.
AT-7687 is a peptide designed to be co-administrated with current or future obesity therapies including GLP-1 medicines to deliver superior weight loss and metabolic benefits. This flexibility in dosing provides multiple advantages over competing GIPR blockers such as antibodies directly conjugated to GLP-1. These include the ability to optimally drug each target for maximal efficacy and tolerability. In addition, AT-7687 also can be used as a single agent in the maintenance setting.
In non-human primate studies, AT-7687 plus a GLP-1 produced best-in-industry weight loss. Furthermore, AT-7687 improved glycemic control and lipid profiles independent of weight changes. Importantly, these benefits were achieved without gastrointestinal side effects.
The U.S. Food and Drug Administration (FDA) recently accepted Antag’s Investigational New Drug (IND) application for AT-7687, setting the stage for clinical development to begin early next year. The trials will explore the effects of AT-7687 as both a monotherapy and in combination with a GLP-1 receptor agonist in obese patients. Antag’s pipeline also includes combinations beyond GLP-1 receptor agonists and a follow-on molecule that enables monthly administration.
“The backing of such a strong syndicate of global investors is a testament to our pioneering approach to developing novel therapies for patients with obesity,” said Alexander Hovard Sparre-Ulrich, Ph.D., CEO and co-founder of Antag. “Coupled with our recent IND clearance, this investment allows us to accelerate the development of AT-7687 towards important clinical milestones. We believe our first-in-class peptide’s weight loss profile and flexible dosing will be key drivers of differentiation.”
“Antag’s peptides will have important advantages given their ability to be used alone or optimally combined with other incretin-based agents, in both weekly or monthly formats,” said Alex Mayweg, Ph.D., Managing Director at Versant and an Antag board member. “GIP receptor antagonism is just beginning to reveal its incredible potential, both in diabetic and non-diabetic obesity, and we are pleased to be at the forefront of this developing field.”
“Novo Holdings was the first investor in Antag and we were excited by great science and a world-renowned founder team,” said Jeroen Bakker, Partner, Seed Investments, Novo Holdings. “We are proud to close this Series A round, which brings several blue-chip investors on board. This funding marks a pivotal step in advancing Antag’s pipeline, which we are confident could play a crucial role in further improving the lives of people with obesity.”
