Trial ended April 2021.
Patient Disease:
Canine Soft Tissue Sarcoma
Study Name:
Contrast Enhanced Ultrasound in Dogs with Soft Tissue Sarcomas
Purpose of the study:
- To evaluate a new form of ultrasound to measure changes in blood flow within soft tissue sarcomas (STS) treated with toceranib and cyclophosphamide as a predictor of benefit, and compare ultrasound with standard tests like CT scan and biopsy
Primary Eligibility Criteria:
- Dogs with a confirmed diagnosis of soft tissue sarcoma that is at least 3 cm in diameter and accessible for biopsy
- Good function of liver and kidneys, acceptable blood cell counts, and free of severe underlying disease
- Three week washout from chemotherapy; 6 weeks from radiation therapy; no prior treatment with toceranib or cyclophosphamide (or similar drugs)
- Pets must come to CSU for all visits related to the clinical trial
Study Protocol:
- Once enrolled, dogs will start treatment with toceranib and cyclophosphamide; this study does not have a placebo group – all dogs will receive treatment with toceranib and cyclophosphamide.
- Dogs will undergo small biopsies before treatment starts, and 6 weeks after starting
- CT scans will be performed before treatment, and 6 weeks after starting treatment
- Ultrasound examinations with a novel contrast agent that is injected intravenously will be performed before treatment, and 1, 2, 3, 4, 6 and 8 weeks after treatment is started
Owner Responsibilities:
- Follow appointment schedule required by study protocol
- Administer oral medications at home to your pet
Financial Incentives:
- Toceranib and cyclophosphamide will be provided at no cost, including after completion of the initial 8-week study period
- All procedures related to the clinical trial will be covered by the study as well as treatment of any side effects that occur
- Following completion of the clinical trial, a credit of $1000 will be applied to the VTH account for continued treatment at CSU
