GamaMabs Pharma raises €15m in series B financing round

BioDiscovery 4, a fund managed by Edmond de Rothschild Investment Partners, led the round; the funds raised will finance clinical trials for GM102, a therapeutic antibody targeting gynecological cancers

Toulouse and Paris, France, December 15, 2015 – GamaMabs Pharma, a biotechnology company developing optimized therapeutic antibodies for the treatment of cancer, today announces the completion of a €15m ($15.9m) series B financing round. The round was led by a new investor, BioDiscovery 4, a fund managed by Edmond de Rothschild Investment Partners (EdRIP). All existing GamaMabs investors (InnoBio, Irdinov, Alto Invest, iXO Private Equity) also subscribed to the round. The company raised €3.6m ($3.8m) in 2013 in a series A funding round led by InnoBio (Bpifrance).

The fundraising will primarily fund the phase I and phase II clinical trials of GM102 (3C23K), a monoclonal antibody targeting gynecological cancers. GM102 is a first-in-class antibody and the company’s most advanced product. It targets AMHRII, a protein expressed on tumor cell’s membrane surface in various gynecological cancers. It also activates immune cells present in the tumor microenvironment. The first-in-man clinical trials of GM102 will start in the first half of 2016.

“We are thrilled to welcome EdRIP, a high profile investor that supports our goal to build GamaMabs into a market leader specialized in the treatment of gynecological cancers,” said Philippe Boucheron, deputy director of life sciences at Bpifrance Investissement. “The company is now well equipped to demonstrate the clinical benefits of its products.”

“We are delighted with the trust expressed by EdRIP and all our current investors. This fundraising will fund proof-of-concept clinical trials on our GM102 antibody in patients with recurrent gynecologic cancers which represent major unmet medical needs,” said Stéphane Degove, CEO of GamaMabs Pharma.

“This financing concludes a very positive year for GamaMabs, including successfully completed GM102 preclinical trials, demonstrating its very favorable efficacy-safety profile,” said Dr. Jean-François Prost, VP R&D and Strategy at GamaMabs Pharma.

Following the fundraising, Gilles Nobécourt, partner at EdRIP, and Prof. Thierry Hercend will join GamaMabs Pharma’s board of directors.
