AB Science will present phase 3 results in severe systemic mastocytosis  at the Journées Dermatologiques de Paris 2016, organized by the French Society of Dermatology

Important step in the rapid treatment of patients in case of masitinib marketing authorization

AB Science SA (NYSE Euronext - FR0010557264 - AB), a pharmaceutical company specializing in the research, development and commercialization of protein kinase inhibitors (PKIs), today announced that results from its phase 3 trial in severe systemic mastocytosis have been selected for an oral presentation at the congress 'Journées Dermatologiques de Paris 2016', organized by the French Society of Dermatology (December 6 - 10, 2016, Paris, France).

The Journées Dermatologiques de Paris is the annual congress of the French Society of Dermatology. This congress hosts more than 5,000 professionals from all over the world with an interest in dermatology, with a program that promotes research and education.

Abstracts were selected by the selection committee of the Congress (three independent readers and one Jury plenary meeting), on the basis of their scientific quality. The abstract for this presentation will be published in the scientific journal 'Annales de Dermatologie et de Vénéréologie' (Volume 143, Issue 12, Supplement, December 2016, Pages S188-S189).

Professor Olivier Hermine, President of the Scientific Committee of AB Science and coordinator of the Reference Center for Mastocytosis (CeReMast, Paris, France), will deliver this oral presentation on Thursday, 8^th December.

Professor Olivier Hermine said: "For indolent forms of mastocytosis, the diagnosis of the disease is often first made by dermatologists, since both cutaneous and systemic forms of mastocytosis are typically associated with cutaneous symptoms, leading to a dermatologist consultation. It is therefore very important that dermatologists are aware of the results for masitinib in this indication. We are very pleased with the interest shown by the dermatologist community, because their intervention represents an important step in the rapid treatment of patients in case of possible future marketing authorization for masitinib in this indication".

• Abstract and schedule

 

Masitinib for the treatment of severely symptomatic indolent and smouldering systemic mastocytosis: a randomized, placebo-controlled, phase 3 study

Abstract: # JDP2016/ABS-1757

Session Title: Thérapeutique 1

Date, Location: Thursday, December 8 (4.15pm), Room: Amphi Havane

• About the phase 3 study in severe systemic mastocytosis

The phase III study results showed that masitinib was superior to optimal symptomatic treatment on the primary efficacy analysis as well as secondary efficacy analyses. This phase 3 randomized study compared masitinib plus optimal symptomatic treatment versus placebo plus optimal symptomatic treatment in adult patients with severe systemic mastocytosis, with or without D816V mutation of c-Kit. Study results showed that masitinib administered at 6 mg/kg/day was superior to the comparator, as measured by the cumulative 75% response rate until week 24 on the handicaps of pruritus or flushes or depression or fatigue (4H75% response). The 4H75% response was 18.7% for the masitinib treatment-arm versus 7.4% for the placebo treatment-arm (p=0.0076, Odds ratio=3.63) in the mITT population (primary analysis). Success in the primary analysis was also supported by positive outcomes in secondary analyses.

Based on these results, AB Science filed for registration to European Medicines Agency (EMA) in April 2016.

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.
