Arthritis affects cats much like it does people, causing pain and stiffness in joints. But cats don’t complain much, so you may not even notice the signs.

An important FDA-regulated clinical trial is underway to evaluate a proposed new injectable treatment for arthritis in cats.

If your cat has signs of reduced mobility (see FAQ below) but hasn’t been recently treated for arthritis, your cat may be eligible to participate.

The first step is to find out if there’s a clinical investigator (veterinarian) in your area. Then ask your veterinarian if your cat might be eligible.

Participation is free, and the study is important!

  • Exams, bloodwork, and x-rays (if needed) are provided to participating cats and paid for by the study sponsor
  • You can keep copies of the diagnostic test results after the study
  • Your participation could lead to a new kind of drug to treat painful osteoarthritis in cats
  1. How would I know if my cat has arthritis?

    You may notice changes in your cat’s behavior, such as:

    • Reluctance to exercise
    • Stiffness after exercise
    • Reluctance to jump on furniture or go up or down stairs
    • Reduced grooming
    • Licking or chewing the affected joints
  2. Any one of these behaviors can be an indication that your cat is in pain, and should be discussed with your veterinarian.

  3. I thought arthritis was a disease of older cats?

    Even younger cats can develop arthritis, particularly active cats or cats that have had a joint injury. Veterinary medicine is recognizing the early signs of arthritis in pets and seeking ways to slow the progression of the disease to help ensure pets can live long and active lives.

  4. What is a clinical trial?

    Just like new medications for people, new drugs for pets must be tested for safety and effectiveness. Safety studies of the test medication are already completed. This specific study is regulated by the US Food and Drug Administration (FDA) and will evaluate effectiveness of a potential new injectable treatment for arthritis in cats.

  5. What are the benefits of participating in this clinical study?
    • No-cost diagnostic tests and evaluation: Participating cats may receive the following study-related medical services: exams, bloodwork, and x-rays (if needed). All study-related medical services are provided at no cost.
    • No-cost treatment (or placebo). Your cat will either be given the test drug or a placebo.
    • Your cat will be part of a study designed to bring a new drug to the US.
  6. How do I participate?

    Your veterinarian will help you schedule an appointment for a preliminary evaluation of your cat with the clinical investigator (a veterinarian) in your area. You can search for an investigator by zip code here.

  7. Are there any risks involved to my cat?

    As with any medical treatment, there are risks and benefits. The study investigator will cover these with you at the preliminary evaluation.

  8. Are there any costs involved?

    No. Costs for all tests and treatments required for the study are paid by the study’s sponsor.

  9. Is there any chance my cat would receive a placebo?

    Cats will be randomly assigned to receive either the test medication or a placebo. Neither you nor the study investigator (veterinarian) will know whether your cat is receiving the test medication or the placebo until the conclusion of the study.

  10. What will be expected of me if I enroll my cat?

    You must be willing to take your cat to the study investigator’s hospital for scheduled visits.

  11. Can all cats participate?

    Cats may be considered for enrollment if they:

    • Have a medical history and exam consistent with osteoarthritis
    • Have not participated in a clinical study for arthritis within the last 6 months
    • Have not had surgery of the affected joint within the past 2 months
    • Have not been given pain medications, steroids, or nonsteroidal anti-inflammatory drugs (NSAIDs) for osteoarthritis within the past 2 months
    • Have no other untreated, uncontrolled illness
    • Are not pregnant or believed to be pregnant
    • Meet other criteria which will be explained by the clinical investigator
