Paris and Toulouse, France, November 12, 2018 – GamaMabs Pharma, a biotechnology company developing optimized therapeutic antibodies targeting the Anti-Müllerian Hormone Receptor II (AMHRII) for the treatment of cancer, today announces its presentation of new data regarding its First-In-Class GM102 antibody at two upcoming conferences.
Clinical data for 20 Granulosa Cell Tumor patients treated with GM102 in the C101 clinical study, will be presented at the EORTC–NCI–AACR 2018 Symposium, Dublin (Ireland), on November 13-16, 2018. The poster describes safety and hints of activity of GM102 in this orphan disease with high unmet need and no approved therapy.
“Following the first results of the C101 study in gynecological cancers published at ASCO this year, we will present additional clinical data for the subset of granulosa ovarian cancer patients who do not have therapeutic alternatives at this stage in their disease,” said Dr. Isabelle Tabah-Fisch, Chief Medical Officer at GamaMabs Pharma
Unveiled activation of T-cells by GM102 following macrophage activation and synergy with immune-checkpoint inhibitors targeting T-cells, will be presented at the AACR 2018 Conference on Tumor Immunology and Immunotherapy, Miami (Florida) on November 27-30.
“We are looking forward to presenting new data on T-cell activation induced by GM102, confirming the potential of our mAb as a single agent and in combination with immune-checkpoint inhibitors,” said Jean-François Prost, Chief R&D Officer at GamaMabs.
The presentation details are:
- EORTC–NCI–AACR Symposium 2018
- Title: ‘GM102, a first-in-class monoclonal glyco-engineered antibody (Ab) targeting Anti-Mullerian-Hormone-Receptor II (AMHRII): safety and hints of activity in Granulosa Cell Tumors (GCT)’, Leary A.

GM102 is a first-in-class glyco-engineered (low-fucose) monoclonal antibody selectively targeting AMHRII-expressing tumors. AMHRII, an embryonic receptor involved in the regression of the Müllerian ducts in the male embryo, is constitutively expressed in ovarian granulosa tumors (GCT) and is re-expressed in a majority of tumor samples in a wide range of gynecological and non-gynecological tumors such as colorectal and lung cancers, hepatocarcinoma or renal cell carcinoma. GM102 is currently being studied in two clinical trials, a phase 1b in recurrent gynecological cancers and a phase 2 in advanced or metastatic colorectal cancers.
GM102 exerts its anti-tumor activity through NK cell and macrophage engagement in the tumor microenvironment, resulting in enhanced tumor phagocytosis and subsequent T cell activation.
Following presentation, the two posters will be available on the publication page of GamaMabs’ website.
