Background: Rabacfosadine (RAB, Tanovea‐CA1) is a novel chemotherapy agent conditionally approved for the treatment of lymphoma in dogs. Hypothesis/Objectives: To determine the efficacy and safety of RAB in dogs with lymphoma. Animals One hundred and fifty‐eight client‐owned dogs with naïve or relapsed multicentric lymphoma were prospectively enrolled from January to October 2019. Methods: Dogs were randomized to receive RAB or placebo at a 3 : 1 ratio. Treatment was given every 21 days for up to 5 treatments. Study endpoints included progression‐free survival (PFS), overall response rate (ORR) at a given visit, best overall response rate (BORR), and percent progression free 1 month after treatment completion. Safety data were also collected. Results: The median PFS was significantly longer in the RAB group compared to placebo (82 vs 21 days; P <.0001, HR 6.265 [95% CI 3.947‐9.945]). The BORR for RAB‐treated dogs was 73.2% (50.9% complete response [CR], 22.3% partial response [PR]) and 5.6% (0% CR, 5.6% PR) for placebo‐treated dogs (P <.0001). One month after the last treatment, 37 RAB‐treated dogs (33%) were progression free compared with no placebo‐treated dogs (P <.0001). The most common adverse events observed in the RAB group were diarrhea (87.5%), decreased appetite (68.3%), and vomiting (68.3%) and were generally low grade and reversible. Serious adverse events were reported in 24 RAB‐treated (20%) and 5 placebo‐treated dogs (13%). Conclusions and Clinical Importance: Rabacfosadine demonstrated statistically significant antitumor efficacy in dogs with lymphoma when administered every 21 days for up to 5 treatments as compared to placebo.
