Our translational research program focuses on a comparative approach, utilizing immunologically intact, canine patients with spontaneous cancer.

This comparative approach provides a unique opportunity to evaluate the safety and effectiveness of next generation immunotherapies in a parallel canine patient population that presents the same challenges to effective immunotherapy as seen in human patients.

The aim of this approach is to accelerate the translation of the most promising pre-clinical discoveries into the human clinic. Our lab is actively involved in developing the canine “model” for evaluating CART cell therapies.

We have successfully translated several promising strategies to generate anti-tumor immunity from the lab and pre-clinical murine models into client owned dogs suffering from lymphoma, osteosarcoma and hemangiosarcoma.

Our lab evaluates the immunological consequences of immune–based therapies in client owned dogs using flow cytometric phenotyping and functional assays including cytokine production, cytotoxicity assays and ELISpot assays to investigate canine T cell responses.

Dr. Mason leads a multi-institutional clinical trial evaluating the safety and efficacy of a recombinant Listeria to prevent metastatic disease in dogs with osteosarcoma. She also leads the coordinating center for Canine Cancer Immunotherapy Trials (U24) as part of the Cancer Moonshot program. The lab has extensive experience in methodology to robustly expand and genetically modify canine T cells ex vivo and is the first to perform clinical trials using CART cells in client owned dogs with treatment naïve or relapsed B-NHL. This single site trial is performed at the Veterinary Hospital of the University of Pennsylvania.
