– Early clinical data of naked monoclonal antibodies support safety of targeting anti-Müllerian hormone receptor 2 (AMHR2), an oncology target of interest  ̶

– Antibody-drug conjugates (ADCs) targeting AMHR2 could provide clinical efficacy in gynecologic, colorectal and other forms of cancer  ̶

ALAMEDA, Calif. and TOULOUSE, France – May 4, 2021 – Exelixis, Inc. (Nasdaq: EXEL) and GamaMabs Pharma SA today announced that they have entered into an agreement under which Exelixis will, upon the future closing of the asset purchase and subject to certain conditions to closing, acquire all rights, title and interest in GamaMabs’ AMHR2 antibody technology.

Toulouse and Paris, August 31, 2020

GamaMabs is deeply saddened to learn the death of Isabelle Tabah-Fisch, its former Chief Medical Officer, on August 28.

Isabelle joined GamaMabs Pharma in November 2016 to bring us her remarkable expertise in Oncology and her high-level network which enabled her to design and implement our clinical trials, until her retirement in March 2020.

Despite the illness that affected her for two years, Isabelle displayed admirable professionalism, courage and energy.

Beyond her professional qualities, we will always remember Isabelle’s great vitality, her joie de vivre, her motivation for therapeutic progress and her ethical standards.

Our hearts go out to Isabelle’s family, especially her father and 3 children.

May Isabelle rest in peace.
