Definitions

  • the present invention relates to a method for treating fibrodysplasia such as fibrodysplasia ossificans progressive comprising administering a compound capable of depleting mast cells or a compound inhibiting mast cell degranulation, to a human in need of such treatment.
  • a compound capable of depleting mast cells or a compound inhibiting mast cell degranulation can be chosen from c-kit inhibitors and more particularly non-toxic, selective and potent c-kit inhibitors.
  • said inhibitor is unable to promote death of IL-3 dependent cells cultured in presence of IL-3.
  • Fibrodysplasia ossificans progressiva is an extremely rare and disabling genetic disorder of connective tissue. The condition is characterized by congenital malformation of the great toes and by progressive heterotopic ossification of the tendons, ligaments, fasciae, and striated muscles. Fibrodysplasia ossificans progressiva occurs sporadically and is transmitted as a dominant trait with variable expression and complete penetrance. Reproductive fitness is low. There are fewer than 150 known patients with the disorder in the United States. A point prevalence of one affected patient in every 2 million of population has been observed. There is no sexual, racial, or ethnic predilection. This disease appears in early life and its course is unavoidably progressive.
  • Mast cell density at the periphery of FOP lesional tissue has been observed to be significantly greater than in normal control skeletal muscle.
  • Mast cells are tissue elements derived from a particular subset of hematopoietic stem cells that express CD34, c-kit and CD 13 antigens (Kirshenbaum, 1999 and Ishizaka, 1993). Immature MC progenitors circulate in the bloodstream and differentiate in tissues.
  • Mast cells produce a large variety of mediators categorized into three groups: preformed granule-associated mediators (histamine, proteoglycans, and neutral proteases), lipid- derived mediators (prostaglandins, thromboxanes and leucotrienes), and various cytokines (IL-1, IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, TNF- ⁇ , GM-CSF, MIP-lo, MIP-1/3 and IFN- ⁇ ), most of them having strong pro-inflammatory activities. For instance, a massive release of MCs mediators is responsible for anaphylactic reactions that could be sometimes fatal to the patients and are always responsible for a significant morbidity. Since MCs are distributed in almost all the body sites, hypersecretion of mediators by activated elements can lead to multiple organ failures.
  • mast cells are central players involved in genetic disorders such as fibrodysplasia.
  • c-kit inhibitors as a new route for treating fibrodysplasia ossificans progressiva, which consists of destroying mast cells playing a role in inflammation and development of FOP lesions.
  • the present invention relates to a method for treating fibrodysplasia and related disorders comprising administering a compound capable of depleting mast cells or blocking mast cells degranulation to a human in need of such treatment.
  • Said method for treating fibrodysplasia can comprise administering a c-kit inhibitor to a human in need of such treatment.
