Leading the Pack in Companion Animal Oncology


A New Way to
Treat Cancer in
Companion Animals

When current treatment options aren’t right for pets with cancer, Torigen offers a different solution. We’re making personalized cancer treatment accessible for you and your clients. Our vaccine works as a supplement to surgery, radiation therapy, and chemotherapy. We utilize a surgically resected portion of tumor to capture the entire repertoire of potential antigens to include in a personalized cancer immunotherapy.

Immunotherapies are gaining traction in both the human and veterinary market as a sole, or adjunct treatment to chemotherapy and/or radiation. With over 10 years of supporting pre-clinical research, our treatment is a whole-cell tissue vaccine. Treatments like these allow for a variety of tumor-associated antigens to be presented to the immune system. This abundant choice of antigens may increase the likelihood of a successful response.


Immunotherapeutic approaches to cancer are emerging that will complement surgery, radiation therapy and chemotherapy by generating specific adaptive immunity to both tumor cells and altered host tissues. Tumors evade normal immune surveillance mechanisms through a variety of means. Some of these include interfering with dendritic cell antigen presentation, down-regulation of cytokines that can destroy tumor cells, stimulation of regulatory (suppressor) T-cells, and by altering host tissue to further mask it from the immune system. Our goal at Torigen is to develop innovative veterinary cancer treatments that allow for the body to recognize tumor-associated antigens as foreign and overcome immune senescence.
