Clinical trials for Orthopedics specialty

  • Description:

    Standard MRI protocols in small animals use contrast material (gadolinium) via intravenous administration to fully assess a disease process. The dose of the contrast material is generally based on body weight; however, in horses this makes the use of contrast cost prohibitive.

    This study will add information about equine MRI and will determine if regional limb perfusion is a feasible way to deliver contrast medium and allow for better characterization of common injuries in equine athletes. The goal is to determine if this method of contrast material administration will allow increased sensitivity of lesion detection while keeping the overall price of contrast administration reasonable

    Inclusion Criteria:

    • Horses: any sex, age, weight
    • Any horse undergoing MRI as part of its lameness work up for lameness localized to the foot/distal limb.


    Client Benefits:

    The study will cover all of the costs associated with the regional limb perfusion as well as the additional anesthesia time and additional MRI sequences. Your horse’s participation will also allow us to gain information about any current injury and will help in the diagnosis of other horses with injuries in the hoof capsule. You understand that your animal’s participation in this study may not alleviate or cure his/her ailment.

  • What is osteoarthritis?

    Osteoarthritis (OA) is a progressive degenerative disease of the joints. The body parts making up the joint become worn out and can be swollen, stiff, and painful. Osteoarthritis is a common condition in dogs. Signs of osteoarthritis often develop slowly. Dogs may develop increased stiffness, especially after rest, or during cold weather. Dogs with osteoarthritis pain may become less active during play, during walks, when going up or down stairs, or jumping. These can be signs of osteoarthritis, and can reduce the quality of your pet’s life.

    Objective of the clinical trial: 

    The objective of this study is to evaluate the efficacy and safety of two investigational drugs in dogs diagnosed with pain due to osteoarthritis of joint(s) of the legs (shoulder, elbow, hip, and knee).

    What qualifies my dog for enrollment in this in this trial?

    To participate in this clinical trial, your dog must have:
    •    Diagnosis of pain due to osteoarthritis of joint(s) in hind and/or forelimb(s). At least one joint must be affected.
    •    Dogs at least two years of age and weighting between 15-50 kg at visit 1.
    •    Generally healthy dogs with no evidence of other serious chronic disease.
    •    Owner must be able and willing to comply with the visit schedule, dosing instructions and other responsibilities during the study.
    •    Must have been on the same diet for at least one month before visit 1, and remain on same diet throughout study.
    Other specific inclusion and exclusion criteria will be used to determine eligibility for enrollment.

    What does enrolling my dog in this clinical trial involve? 

    If your dog qualifies for the study, and you agree to participate, your dog will be randomly assigned to one of four treatment groups. You will be required to administer study medication twice daily for approximately 14 days, as capsules that are given to the dog by mouth. Each dog will receive, either an investigational drug, carprofen (a traditional non-steroidal anti-inflammatory drug) or a placebo. Treatment groups will be is randomly assigned. Neither you, nor the veterinarian, will know your dog’s treatment group.

    Client Compensation

    All study procedures, including the study’s required radiographs (and associated sedatives if needed), office visits, and laboratory tests are provided free of charge. In return for your dog’s enrollment and your participation in the study, you will be eligible to receive a $150 Visa gift card provided your dog is not withdrawn due to non-compliance and you complete the study. If your dog is withdrawn due to other factors, you would be compensated for the portion for the study you did complete.
