Predictive Models of Drug Response in Canine Osteosarcoma

Patient Disease:

Canine Osteosarcoma

Study Name:

Predictive Models of Drug Response in Canine Osteosarcoma: A Prospective Clinical Trial Testing the COXEN Approach

Purpose of the study:

  • Use a model (COXEN) to predict which of the standard chemotherapy protocols an individual dog’s tumor is most sensitive to

  • Administer (post amputation) chemotherapy to the patient based on the predictions generated by the model

  • Determine if this gives better outcomes for those patients (longer survival)

Primary Eligibility Criteria:

  • Dogs with confirmed or suspected diagnosis of osteosarcoma of a limb, with no evidence of metastases (chest x-rays)

  • Dogs must be free of other serious diseases (physical exam, blood tests)

  • All dogs must have amputation as the treatment of the tumor, performed at CSU

  • They cannot have had any prior treatment for the tumor

Study Protocol:

  • Initial screening tests (physical exam, blood and urine test, x-rays of the affected limb and chest)

  • Surgery to amputate limb (tumor samples will be analyzed by COXEN method)

  • Further visits will be for blood tests, chemotherapy treatments (determined based on COXEN results of tumor analysis),  and intermittent chest x-rays

Owner Responsibilities:

  • To make and keep all study related appointments

  • Owner is responsible for finances, aside from the points listed below

Financial Incentives:

  • The study pays for the cost of the COXEN analysis to determine drug sensitivity of tumor

  • The study pays for chest x-rays until the development of metastatic disease

  • The owner would be responsible for all other costs associated with the dogs treatment and participation in this study
