AACR 2018: GamaMabs Pharma to present new data on expression of Anti-Müllerian Hormone type II Receptor in non-gynecological cancers and on first ADC candidate targeting AMHRII

AMHRII expression and Antibody-Drug Conjugate preclinical data suggest potential broader applications for anti-AMHRII-based therapy

GamaMabs Pharma, a biotechnology company developing optimized therapeutic antibodies targeting AMHRII for the treatment of cancer, today announces the presentation of two posters on its AMHRII program at the upcoming American Association for Cancer Research (AACR) annual meeting, taking place from April 14 to 18 in Chicago, USA.

The results of extensive investigations show AMHRII expression in a majority of tumor samples in a wide range of non-gynecological tumors such as colorectal and lung cancers, hepatocarcinoma or renal cell carcinoma. Moreover, internalization capabilities and selective distribution of the target have been utilized to design a first AMHR2 based ADC approach.

The presentation details are as follows:

  • Title: Anti-Müllerian Hormone type II Receptor (AMHRII) found expressed in human non-gynecological solid tumors, suggesting potential broader applications for anti-AMHRII-based therapy
    • Abstract number: 774
    • Date and time: April 15, 2018, 1pm – 5pm (CT)
    • Session category/title: Experimental and Molecular Therapeutics
    • Location: Section 36
  • Title: Anti-Müllerian hormone type II receptor (AMHRII), a cancer target for GM103, a novel antibody-drug conjugate (ADC)
    • Abstract number: 1779
    • Date and time: April 16, 2018, 8am – 12pm (CT)
    • Session category/title: Therapeutic Antibodies, including Engineered Antibodies 1
    • Location: Section 34

The studies were performed with GamaMabs’ partners, including the Curie Institute (Paris, France), the Gustave Roussy Institute (Villejuif, France), Massachusetts General Hospitals (Boston, USA), the Léon Bérard Cancer Center (Lyon, France), Nantes University Hospital (France), the Cancer Research Institute, Montpellier (France), Abzena (UK) and Helsinki University Hospital (Finland)

“We are happy to be able to share such groundbreaking data on AMHRII expression, unveiling its potential as a novel target in a wide range of solid tumors,” said Jean-François Prost, VP R&D at GamaMabs. “The results with GM103 clearly show, as a proof of concept, that AMHRII is also a suitable target for treating AMHRII-positive solid tumors with an ADC.”

“We are committed to expanding our development plans beyond gynecological cancers, in particular for our lead program GM102,” said Stéphane Degove, CEO at GamaMabs.

A copy of the above referenced abstracts can be viewed online through the AACR meeting website. Following the presentation, the data presented will be available on the Publications page of GamaMabs’ website.
