GamaMabs Pharma starts phase Ia/Ib study of first-in-class monoclonal antibody GM102 in advanced gynecological cancer

First trial of mAb targeting anti-Müllerian human receptor II tested in oncology patients

Initial results expected in 2017


Toulouse and Paris, France, July 26th, 2016 GamaMabs Pharma, a biotechnology company developing optimized therapeutic antibodies for the treatment of cancer, today announces the first administration to a patient of GM102, its first-in-class monoclonal antibody (mAb) targeting the anti-Müllerian human receptor II (AMHR2/MISR2) in gynecological cancers. The first administration took place at the Jules Bordet Institute in Brussels, Belgium, as part of a phase Ia/Ib study in AMHR2-positive patients with advanced pre-treated gynecological cancer. The primary objective is to assess the safety of GM102 and to select a dose for future Phase Ib/II trials.

GM102 is a first-in-class mAb, bringing increased tumor cell killing properties through the activation of immune system cells, thanks to its EMABling® glyco-engineering technology.

“We believe that the mechanism of action of GM102 is well suited to gynecological cancers, such as ovarian, endometrium and cervical cancers. It has the potential to improve the treatment of relapsing patients,” said Prof Ahmad Awada, principal investigator of the study at the Jules Bordet Institute.

“As this is the very first time an AMHR2-targeting drug is being tested in oncology patients, we are very excited about generating data that can guide us through the development of GM102 in Phase II. We are extremely pleased with the accrual rate at Jules Bordet, to which French centers will be soon aggregated” said Jean-François Prost, VP R&D at GamaMabs Pharma.

“This is a major milestone for our company after only three years of activity,” said Stéphane Degove, CEO of GamaMabs Pharma.

Following the expected completion in 2017 of the first stage of this dose-escalation study, GamaMabs is planning to initiate a second stage, consisting of two expansion cohorts in gynecological cancers.

 About GamaMabs Pharma

GamaMabs Pharma is a French biotechnology company developing innovative monoclonal antibodies in cancer. GamaMabs Pharma’s lead project is the first-in-class monoclonal antibody (mAb), GM102. This antibody, which targets the anti-Müllerian human receptor II (AMHR2/MISR2) in gynecological cancers, entered a phase I clinical trial in H1 2016. Initial results are expected in 2017. Ovarian cancer is responsible for almost 60,000 deaths every year in Europe and the United States (Source: Globocan 2012/WHO). The company develops low-fucose EMABling® antibodies (license granted by LFB) with increased tumor cell killing properties through the activation of immune system cells.
