Clinical Trials
Clinical trials are programs that allow researchers to study the effects of new “experimental” treatment options, with the hope of finding new and improved ways to treat cancer. There may be a clinical trial available for your pet to join either instead of more traditional treatment, or in the case of those traditional treatments failing.

Clinical trials help researchers figure out if new treatment options are safe and effective, whether there are any side effects or risks to the patient, and whether the new treatment is potentially better than existing options.

Advantages to allowing your pet participate in a clinical trial include receiving a new drug before it is widely available – potentially at decreased or no cost to you. Also, since many cancers in animals similarly occur in humans, you and your pet may be helping to pave the way for successful treatment methods that benefit both animals as well as humans.

Disadvantages exist because of the experimental nature of the treatment – although the effectiveness must first be proven in laboratory animals, there is a possibility of unexpected side effects to your pet. You will always reserve the right to remove your pet from a clinical trial at any point if you would like to pursue other avenues of treatment.

Please feel free to talk to any of our doctors to find out about any new clinical trials that may be available to your pet or how to participate in any of the studies listed below.
 
Current Clinical Trials - Conducted at VOHC
Trial Description

Funded Trial for Metastatic Osteosarcoma
Trial Eligibility Criteria Include:
   • Client-owned pet dogs
   • Histopathological diagnosis of appendicular osteosarcoma associated with prior amputation or limb-salvage surgery to address the primary lesion
   • Measurable osteosarcoma pulmonary metastasis (based on radiographs)
   • No concurrent medical disorder or infectious illness which is likely to result in death or euthanasia within 2 months as a result of this condition
   • No surgical procedure within 14 days of study initiation
   • No chemotherapy within 21 days prior to the start of the study
   • No radiation therapy within 21 days prior to the start of the study
   • No investigational therapy within 21 days prior to the start of the study

Trial Support/Funding Includes: The study provides complete funding for examinations, blood/urine tests, radiographs, and study medication once eligibility has been confirmed.

Evaluation of a New Therapeutic Option for Mast Cell Tumors
Trial Eligibility Criteria Includes:
   • Dogs with measurable cutaneous mast cell tumor(s).
   • Mast cell tumor histological grade II or III.
   • Dogs in whom curative intent surgery cannot be performed or has been declined by the owner.
   • Regional lymph node involvement accepted.
   • Dogs at any age, weight, gender, breed with satisfactory health: must be at least 5kg.
   • No prior chemotherapy.
   • No radiation therapy to a target lesion. If prior radiation therapy is performed, a 3-week washout is required before study enrollment.
   • Three-week washout period for prednisone, 2-week washout period for non-steroidal anti-inflammatory drugs.

Trial Support and Funding:
There is no placebo included in this trial. Dogs will be randomized 2:1 to initially receive the new investigational drug or an active chemotherapeutic against mast cell tumors, lomustine. The initial consultation fee must be paid by the owner. Once an informed consent form is signed, all diagnostic tests, study drug, follow-up evaluations, and management of potential side effects will be paid for by the study.


Retinoic Acid therapy for Mast cell tumors in Dogs
We are pleased to announce another partially funded clinical trial. This preliminary study is evaluating the effect of an oral retinoic acid derivative on mast cell tumors in dogs. Any dog with a measurable lesion and normal renal and liver function is a potential candidate.

If you have a dog with a mast cell tumor please give Dr. Post or our referral coordinator Maria Salas a call at 203-838-6626



Feline Gleevec Trial
Open to cats with both recurrent, non-resectable or microscopic biopsy-confirmed Mast Cell Tumors or Vaccine-Associated Fibrosarcomas. Gleevec is a novel targeted chemotherapy without the side effects of traditional therapy. The owner is responsible for the purchase of the medication, which is given by mouth once daily at home. Diagnostics required prior to enrollment include blood work and urinalysis.
