Mastivet contains mastinib.

Masitinib is a protein-tyrosine kinase inhibitor which, in vitro, potently and selectively inhibits the mutated form, in the juxtamembrane (JM) region, of the c-kit receptor. It also inhibits the Platelet Derived Growth Factor (PDGF) receptor and the Fibroblast Growth Factor Receptor (FGFR3). In the pivotal clinical field study, dogs of various breeds, ranging in age from two to seventeen years, were randomly treated with Masivet at a dose of 12.5 mg/kg or with a placebo. In dogs with nonresectable mast cell tumours, Grade 2 or 3, expressing a mutated tyrosine kinase c-kit receptor, treatment with Masivet showed a significantly longer Time-to-Tumour Progression (TTP) with a median of 241 days as compared to 83 days for placebo. Response to treatment with masitinib was expressed as stable disease; i.e. static, partial or complete response. Masitinib treatment should only be used in dogs with non-resectable mast cell tumours, which express the mutated c-kit tyrosine kinase receptor. The presence of a mutated tyrosine kinase c-kit receptor must be confirmed prior to treatment.
