TANOVEA® (rabacfosadine for injection) Receives Full FDA Approval as First Treatment for Lymphoma in Dogs; Elanco Acquires Product from VetDC, Inc


Posted By: Sarah Morehouse

GREENFIELD, Ind. (July 19, 2021) Today, Elanco Animal Health Incorporated (NYSE: ELAN) announced that the  FDA has granted full approval of Tanovea for the treatment of lymphoma in dogs, making this the first conditionally approved new animal drug for dogs that has ever advanced from a conditional to full FDA approval under the FDA’s Minor Use and Minor Species (MUMS) program. Concurrently, Elanco announced the acquisition of the product from VetDC, Inc., which it licensed for further development and commercialization in 2019.

With the full approval, Tanovea becomes one of the most comprehensively studied treatment options for canine lymphoma. The robust scientific evidence of Tanovea’s effectiveness and safety in dogs with lymphoma offers a product the veterinary oncology community can rely on as they guide their patients through their lymphoma treatment journey.

“Tanovea provides veterinarians and pet owners with a novel treatment option for canine lymphoma, of which there are few,” said Aaron Schacht, executive vice president, Innovation, Regulatory and Business Development of Elanco. “Working in collaboration with VetDC allowed us to utilize innovation originally intended for humans to demonstrate efficacy in dogs, and ultimately gain full approval from CVM for Tanovea.”

One in four dogs will be diagnosed with cancer in their lifetime – with lymphoma being one of the most common types of cancer seen by veterinarians.1 A lymphoma diagnosis can be a challenging time for pet owners, but with Tanovea, veterinary oncologists can offer renewed confidence with a different treatment option than what they’ve relied on in the past. Tanovea works differently than other commonly used treatments and is specifically designed to target lymphoma cells. 1–4 In the pivotal study, Tanovea demonstrated a statistically significantly longer median progression free survival time (PFS) compared to placebo (p<0.0001), with a median PFS of 151 days in responding dogs (partial or complete response) and 168 days in dogs with a complete response. For dogs with B-cell lymphoma, 80.4% of dogs responded to Tanovea treatment. In addition, Tanovea is dosed in 3-week intervals, allowing more quality time together for pet and owner between treatments.

"We are excited to see our high-science approach of conducting comprehensive clinical studies with leading academic and private veterinary hospitals culminate in this landmark approval", says Steven Roy, President & CEO of VetDC. “I am tremendously proud of the outstanding work and dedication of the entire VetDC team to bring Tanovea to full FDA approval. We are grateful for Elanco's collaborative relationship and look forward to seeing Elanco advance this important lymphoma treatment further within the veterinary oncology community.”
