  • 60



Paris, May 21, 2021, 6pm CET

AB Science SA (Euronext – FR0010557264 – AB) will host a live webcast on May 25, 2021 with key opinion leaders to discuss recently reported results from the Phase 2B/3 masitinib trial in prostate cancer.

The webcast call will be held on Tuesday May 25, 2021 from 6.30pm to 7.30pm CET (12.30pm to 1.30pm ET).

The webcast will feature presentations by three Key Opinion Leaders:

  • Stéphane Oudard, MD, PhD, Chief of the Oncology Clinical and Translational Research Unit at the Georges Pompidou Hospital in Paris, France
  • Theo M. de Reijke, MD, PhD, FEBU, Associate Professor at the Amsterdam University Medical Centers, Amsterdam, The Netherlands
  • Olivier Hermine, MD, PhD, Chief of adults Hematology staff at Hospital Necker in Paris, France, president of AB Science scientific committee and member of the French Académie des Sciences

AB Science, along with these key opinion leaders, will provide:

  • An explanation of the rationale to position masitinib in the treatment of prostate cancer
  • A presentation of the results from the recently reported Phase 2B/3 masitinib clinical trial in prostate cancer
  • A discussion on the positioning of masitinib versus current treatment options in prostate cancer

The presentation will be followed by a Q&A session with the key opinion leaders and management of AB Science.

Masitinib is a tyrosine kinase inhibitor designed to selectively target mast cells and macrophages, through inhibition of c-Kit, Lyn, Fyn, and MCSFR-1 kinases, which are critical components of the tumor microenvironment, promoting angiogenesis and tumor growth, and also contributing to tumorigenesis by suppression of the immune response.

On April 29th, AB Science announced that its masitinib Phase 2B/3 study (AB12003) in metastatic castrate-resistant prostate cancer (mCRPC) eligible to chemotherapy met its predefined primary endpoint.

About masitinib
Masitinib is a new orally administered tyrosine kinase inhibitor that targets mast cells and macrophages, important cells for immunity, through inhibiting a limited number of kinases. Based on its unique mechanism of action, masitinib can be developed in a large number of conditions in oncology, in inflammatory diseases, and in certain diseases of the central nervous system. In oncology due to its immunotherapy effect, masitinib can have an effect on survival, alone or in combination with chemotherapy. Through its activity on mast cells and microglia and consequently the inhibition of the activation of the inflammatory process, masitinib can have an effect on the symptoms associated with some inflammatory and central nervous system diseases and the degeneration of these diseases.
