COTC024: Defining PK and Biological Activity of Systemic Oncolytic Vesicular Stomatitis Virus (VSV) within a Dose/Schedule Optimization Study

Patient Disease:

Canine T Cell Lymphoma 

Study Name:

COTC024: Defining PK and Biological Activity of Systemic Oncolytic VSV within a Dose/Schedule Optimization Study 

Purpose of the study:

  • To define optimal dose and schedule of administration for systemic VSV treatment in dogs with cancer.

  • VSV is a naturally oncolytic virus that has been engineered to possess potent anti-cancer properties with enhanced safety.

Primary Eligibility Criteria:

  • Dogs that weigh at least 20 kg (44lb)

  • Diagnosis of T cell lymphoma

  • Dogs must be feeling well, with adequate routine blood work (blood count, chemistry profile, urinalysis)

  • Dogs must be up to date on all routine vaccinations and parasite control

  • Two week washout from chemotherapy, 6 weeks from radiation therapy, 72 hours from steroids

Study Protocol:

  • Determine eligibility with initial screening: physical exam, blood tests (CBC, biochemistry, urinalysis), confirmation of T cell lymphoma diagnosis, and chest x-rays

  • 1st day of study: Pre-treatment physical exam, tumor measurements, blood samples, lymph node biopsy

  • 2nd day of study: Virus administration, monitoring and blood sampling; must stay hospitalized overnight

  • 3rd & 4th day of study: Exam, blood samples

  • 4 weekly appointments until study end

Owner Responsibilities:

  • Cost of diagnostics to determine eligibility (bloodwork, urinalysis, histological/cytological confirmation of the diagnosis)

  • To make and keep all appointments

Financial Incentives:

  • Once enrolled, the study will pay for all costs associated with the study procedures and treatments

  • Study will also cover cost of side effects attributable to the virus treatment or study procedures (up to  $2000/dog/event)

  • A $2500 credit will be applied to the dog's account at the VTH, which can be applied toward further treatments
