How does TANOVEA®-CA1 work?

TANOVEA®-CA1 is the first lymphoma treatment for dogs that has been conditionally approved by the FDA. Targeting rapidly multiplying lymphoma cells, it mimics a DNA building block, preventing cells from dividing and ultimately causing them to die. The medication is convenient (requiring just five office visits) and generally well tolerated. In clinical trials, 77 percent of dogs with lymphoma responded to treatment with TANOVEA-CA1, even those that had stopped responding to other medications.

  1. We saw a specialist recommened and this was never mentioned!!!!!

    • We’re sorry that Tanovea CA-1 was not an option for you. Each veterinarian has a different selection of treatments for various conditions that they offer, we are working to make Tanovea CA-1 an option for treating lymphoma at every veterinary clinic in the country.

  2. How fast does it start to work? Our dog gets his first treatment tomorrow. His lymphnodes under his mandible are huge and he is starting to have a hard time swallowing. How soon after that first dose, if he responds, does the swelling start to decrease?

    • Sorry to hear about your pup. We will respond via email with additional information, but typically, dogs respond within 7 days of treatment. That being said, every case is different – some dogs have taken much longer to demonstrate noticeable responses – however, you should see something within the next 3 weeks. Your veterinarian will be in the best position to assess, so please keep them in the loop.
      Best wishes for a successful outcome!

  3. I have a Carolina Dog that is 11 years old. She has Mast Cell Tumorss, and now we have just discovered a very large lump under her collar, and the vet feels that it is Lymphoma. Considering the fact that she has Mast Cell Tumors ( 2 surgerys, removing 3 tumors), would you recommend this treatment, or with Mast Cell as well would it not work? We like any other dog owner love her with all our hearts, Please advise if you can help us, Please.

    • So sorry to hear about your pup. We will reach out directly via email.
