GamaMabs Pharma sees two peer-reviewed articles published in Oncotarget, detailing the anti-tumor activity of GM102/3C23K

GamaMabs Pharma, a biotechnology company developing optimized therapeutic antibodies targeting AMHR2 for the treatment of cancer, today announces that two peer-reviewed articles have been published in the prestigious journal, Oncotarget, elaborating on the anti-tumor activity of GamaMabs’ lead compound GM102/3C23K for ovarian cancer. The studies were performed by GamaMabs’ partners, including the Institut de Recherche en Cancérologie de Montpellier, Inserm, Institut Curie and the Institut Gustave Roussy.
GM102/3C23K is a first-in-class monoclonal antibody (mAb) targeting the anti-Müllerian human receptor II (AMHR2/MISR2) which is expressed in a large proportion of gynecological cancers. Having a high affinity towards AMHR2, GM102 displays tumor cell killing properties through the enhanced activation of immune system cells, thanks to its EMABling® glyco-engineering technology. Based on the studies’ positive results a phase Ia/Ib trial with GM102 was launched in July 2016, with initial results expected early 2018.
Both published articles drew favorable conclusions regarding GamaMabs’ GM102/3C23K candidate in pre-clinical models, describing how the compound displays an original antitumor mode of action through the activation of tumor-associated macrophages, which predominantly infiltrate the ovarian cancers. Interestingly, it has been shown that activation of those macrophages by GM102/3C23K triggers high tumor cell killing by phagocytosis followed by unlocking adaptive immune system resulting in anti-tumoral T cell proliferation.
