- 134 day overall median progression-free survival time in responding dogs
- Can be used in dogs with naive and relapsed/refractory lymphoma
Generally well-tolerated in clinical studies 3
- The majority of adverse reactions were Veterinary Cooperative Oncology Group (VCOG)4 grade 1 or 2
- Common adverse reactions included neutropenia, diarrhea, anorexia, weight loss, lethargy, and skin problems

Uptake of the 18F-fluorothymidine tracer via positron emission tomography/computed tomography (PET/CT) following TANOVEA-CA1 treatment.5, 6
Figure A depicts the tracer present in lymph nodes, bone marrow, bladder, kidneys and spleen of a dog with lymphoma prior to treatment.
Figure B shows the same dog nine weeks following TANOVEA-CA1 treatment, with markedly reduced tracer uptake in the lymph nodes, which correlated with a complete response in this dog.
TANOVEA-CA1 mechanism of action
Conditionally approved by FDA pending a full demonstration of effectiveness under application number 141-475.
