For treatment of inoperable
mast cell tumours

(Grade 2 or 3)*


 

Mast cell tumours (MCTs) are the most common cutaneous malignancies in dogs, accounting for 16% to 21% of all skin tumours. MCTs demonstrate a wide range of behaviours, appearance and patterns of progression – all of which make these tumours a challenge to treat.

Whilst surgery is always the first option and the cornerstone of MCT management, anti-cancer medical treatment is needed when complete surgical removal is not possible or where the tumour is highly aggressive or has already spread.

 

Masivet® is prescribed for the treatment of non-resectable (inoperable) high grade mast cell tumours - Patnaik grade 2 and grade 3. 

Masivet® is not a cytotoxic chemotherapy. It is a highly targeted treatment designed to work specifically and selectively on key biological pathways that cause the growth and spread of mast cell tumours.8

Masivet® is an effective, well-tolerated and proven treatment - and it was the first cancer medicine in the UK to be approved and licensed by  the Veterinary Medicines Directorate for the treatment of dogs. 

Masivet® acts systemically and has been shown in clinical studies to induce tumour shrinkage and to significantly prolong time to MCT progression.7  

Masivet® is licensed for the treatment of dogs with non-resectable mast cell tumours (Grade 2 or 3)* and has been shown to have the greatest effect in those tumours with a confirmed mutated c-Kit tyrosine kinase receptor.1,7

Masivet® can be obtained from all major veterinary wholesalers in the UK and in the Republic of Ireland.

How to use Masivet®

 

Masivet® is a prescription-only medicine, administered in tablet form - convenient and simple to use for both pet owners and vets.

Starting dose is 12.5mg/kg once daily and the duration of treatment depends on the degree of tumour response. 

Regular monthly follow-up of the treated patient must be conducted by a vet – including blood biochemistry and haematology monitoring.
