Masivet 50 mg

Masivet® contains the active substance masitinib. Masivet belongs to the so-called protein tyrosine kinase inhibitors. It inhibits the enzyme protein tyrosine kinase (PTK). These enzymes are involved in core cell functions. By inhibiting the enzyme, the growth of certain cells is reduced.

We use Masivet® for the treatment of dogs with mast cell tumors (mastocytoma) with the following characteristics:

  • Malignant mastocytomas (grade 2 or 3).
  • Which cannot be operated on.
  • With a damaged (mutation) KIT receptor.

The effect of the drug must be measurable within 4 to 6 weeks after starting treatment with Masivet®.

If the tumor contains mutated KIT receptors, it takes longer for the tumor to get worse when treated with Masivet®.

  • With Masivet®, the tumor grows after an average of 241 days.
  • Without Masivet® this is after an average of 83 days.
