Brief Summary: The objective of this study is to compare the safety and efficacy of masitinib (AB1010) to placebo in patients with mastocytosis with handicap.

Detailed Summary:

Mastocytosis is a disease characterized by mast cell invasion in various organs. Mast cells are bone marrow derived cells which produce histamine and other substances causing allergic and anaphylactic reactions. Accumulation of mast cells in body organs can inhibit the functionality of the organ and eventually cause degeneration.

Mutations of the mast cell growth factor receptor (KIT protein, the product of the c-Kit proto-oncogene) might be found in patients with mastocytosis.

Masitinib (AB1010) is a tyrosine kinase inhibitor (TKI), selectively and effectively inhibiting c-kit. Its effect may include inhibition of cell proliferation, inhibition of cell cycle progression and induction of apoptosis resulting in the reduction of mast cell accumulation in body tissues. This drug is thereby specific to mastocytosis and active in slowing or reducing the number of mast cells particularly in aggressive forms of the disease.
