Current Clinical Trials

What are clinical trials?

Clinical trials at the OVC HSC are research studies involving client-owned animals with the ultimate goal of advancing animal health care. These studies may try to identify the most effective therapies and practices for a given condition or increase our understanding of a disease process.

Participation in clinical trials at OVC HSC may provide our clients & their companion animals with unique access to new tools and treatments. Clinical research in companion animals may also help humans and vice versa.

For all clinical trials performed at the Ontario Veterinary College, informed consent will be obtained from a patient’s owner. The clinical care of a patient will not be compromised regardless of participation status.

OVC HSC is the first Canadian centre in the Comparative Oncology Trials Consortium (COTC – 20 sites) of the NIH-NCI-Center for Cancer Research’s Comparative Oncology Program set up to conduct clinical trials in dogs with cancer to assess novel therapies! We currently do not have any active studies with the COTC.

Recruitment closed in Nov 2017 for the first study: Standard of Care Therapy with or without Rapamycin in Newly Diagnosed Dogs with Appendicular Osteosarcoma). Published in June 2021: Adjuvant Sirolimus Does Not Improve Outcome in Pet Dogs Receiving Standard-of-Care Therapy for Appendicular Osteosarcoma: A Prospective, Randomized Trial of 324 Dogs. (2021) LeBlanc AK, Mazcko CN, Cherukuri A, Berger EP, Kisseberth WC, Brown ME, Lana SE, Weishaar K, Flesner BK, Bryan JN, Vail DM, Burton JH, Willcox JL, Mutsaers AJ, Woods JP et al. Clinical Cancer Research: 27(11), 3005-3016.

Our second trial in collaboration with NIH-NCI-COTC closed for recruitment in Oct 2019: Evaluation of a recombinant, attenuated Listeria monocytogenes expressing a chimeric human HER2/neu protein in dogs with osteosarcoma in the adjuvant setting. Data analysis currently underway.
