What is Masivet?
50mg Masivet is a round, orange tablet containing 50mg masitinib, which belongs to a class of medicines having an anticancer action.
What is Masivet used for?
Masivet is used to treat dogs with mast-cell tumours (a type of cancer). It is used for tumours which are severe in character (grade 2 or 3) and which cannot be removed with surgery. Masivet is only used if the presence of a mutated form of the receptor protein c-kit in the tumours has been confirmed before the start of treatment. Masivet tablets are given by mouth, once a day. The dose of Masivet depends on the weight of the dog being treated.. The duration of treatment depends on the dog’s response to treatment.
How does Masivet work?
The active substance in Masivet, masitinib, is a protein-tyrosine kinase inhibitor. This means that it blocks some specific enzymes known as tyrosine kinases. These enzymes can be found in some receptors on the surface of cells, including the c-kit receptor. Some types of mast-cell tumour are linked to a mutation that causes excessive action of c-kit and stimulates the mast cells to divide uncontrollably. By blocking these receptors, Masivet might help to control cell division, preventing further development of the tumours with this particular mutation.
How has Masivet been studied?
A number of studies with Masivet were carried out either in laboratory dogs or in animal patients at veterinary practises in Europe and in the USA. The main study compared the effectiveness of Masivet at the recommended dose of 12.5 mg per kilogramme bodyweight once a day with placebo (a dummy treatment). The study included dogs of various breeds and both sexes with mast-cell tumours that had come back after surgery or could not be removed with surgery. The study population included dogs whose tumours contained mutated or normal (‘wild-type’) c-kit receptors.

Palladia - 10mg Palladia Tablets for Dogs - Per Tablet
10mg Palladia is a prescription medication used to treat mast cell tumours in dogs. Each tablet contains 10mg of toceranib phosphate, a targeted therapy designed to slow tumour growth and prevent the spread of cancer cells.
Palladia is the first veterinary-approved cancer treatment specifically developed for dogs. It is commonly prescribed for dogs with grade II or III mast cell tumours that have spread or cannot be surgically removed. This medication works by blocking signals that allow tumour cells to grow, helping to manage the progression of the disease.
How 10mg Palladia Works
Palladia contains toceranib phosphate, a tyrosine kinase inhibitor (TKI) that disrupts cancer cell growth. Tyrosine kinases are enzymes that regulate cell division and blood vessel formation. In mast cell tumours, these enzymes can become overactive, leading to uncontrolled tumour growth.
Palladia works by:
- Blocking tyrosine kinase activity, which prevents tumour cells from dividing and multiplying.
- Cutting off the blood supply to the tumour, restricting its ability to grow.
- Targeting cancerous cells while minimising damage to healthy tissue.
By interfering with these cancer growth mechanisms, Palladia helps slow the progression of mast cell tumours and may reduce their size over time. Some dogs experience tumour shrinkage, while others may see slowed disease progression.
