Versanis Bio Announces $70 million Series A Financing to Advance Bimagrumab for the Treatment of Obesity

Leading life science investors Atlas Venture and Medicxi led the financing with participation from founding investor Aditum Bio

​

Oakland California, August 31, 2021 [NEWSWIRE] – Versanis Bio today announced the closing of its Series A financing of $70 million to advance the clinical development of bimagrumab, an activin receptor type II antagonist. The company was founded and seeded earlier this year by biotech investment firm Aditum Bio to develop a new therapy for the treatment of metabolic disease and obesity following the in-licensing of bimagrumab from Novartis. Atlas Venture and Medicxi co-led the Series A financing with participation from Aditum Bio, positioning Versanis to initiate an advanced phase 2 program for the treatment of obesity.

“Obesity is a growing healthcare challenge worldwide. In the US, more than 40% of the adult population is obese and obesity is linked to some of the most common causes of death including cardiovascular disease and cancer,” said Dr. Lloyd Klickstein, CEO of Versanis Bio. Dr. Mark Fishman, Co-Founder of Aditum Bio and member of the Versanis Bio Board of Directors added, “As people age, loss of muscle mass makes it even harder to lose weight. All existing obesity treatments risk further loss of muscle, together with fat. Bimagrumab is a unique therapy that Versanis is developing to build muscle while markedly reducing fat, providing a potential breakthrough in the obesity epidemic.” Dr. Fishman is joined on the Board of Directors by Michael Gladstone, Partner at Atlas Venture, Nicholas Williams, Principal at Medicxi, and Joe Jimenez, CoFounder of Aditum Bio.

The Series A funding will be used to support a comprehensive phase 2 clinical program to evaluate the potential of bimagrumab to help obese patients lose fat and achieve an improved body composition.

About bimagrumab

Bimagrumab is a highly potent, first-in-class, fully human monoclonal antibody to the activin type II receptors that blocks the binding of ligands including activin A and myostatin. Bimagrumab has been studied by Novartis in more than a dozen controlled clinical trials that enrolled more than 1,500 people. Across key studies bimagrumab treatment consistently and potently induced significant loss of fat mass without loss of lean mass, and additionally improved HbA1c and other cardiometabolic parameters. In a recent study of overweight or obese patients with diabetes, 48 weeks of treatment with bimagrumab led to a 20.5% loss of total body fat mass and a 3.6% increase in lean 2 mass (JAMA Network Open. 2021;4(1):e2033457).
