Am I Eligible?

You or a Loved One May Qualify if You:

  • Are between 40-80 years old
  • Have been diagnosed with moderate to severe Osteoarthritis of the Knee
  • Have been experiencing pain due to OA of the Knee for at least 26 weeks
  • Are willing to complete an electronic diary on a daily basis in the evening for the duration of the 56-week study
  • Have not had a partial or complete joint replacement surgery in either knee

There are additional study requirements to participate.  A study representative will discuss them with you.

About The Strides X-Ray Study

The STRIDES X-Ray study is testing the safety and effectiveness of a new investigational medication, in comparison to a placebo, administered as a single injection in the Knee. Qualified individuals will have the option to participate in a 56-week study, with approximately 9 in-person visits and 8 telephone visits.

Approximately half the subjects in the study will receive placebo, meaning that you have a 50:50 chance of receiving placebo. The study treatment that you receive for the study will be selected at random, similar to flipping a coin.

Are there benefits to taking part in this study?

Taking part in this study may or may not make your OA better. The investigational medication may make your health better, worse, or the same as other treatments that are available. Information from this study may help doctors learn more about treatments for your condition and this information may help other subjects, even if it may not help you.

What is Osteoarthritis?

Osteoarthritis (OA) is the most common form of arthritis, and the major cause of activity limitation and physical disability. Today, 35 million people (13% of the US population) are 65 and older, and more than half of them have radiological evidence of OA in at least 1 joint.

Common symptoms may include:

  • Pain
  • Stiffness
  • A grinding sensation when moving the joints
  • Swelling


What is a clinical research study?

A clinical research study tests the safety and effectiveness of a new investigational medication in human volunteers. Every investigational medication goes through the clinical trial process. Therefore, participants play a very important role in advancing medicine for present and future generations.

What is an investigational medication?

An investigational medication has not been approved by the U.S. Food and Drug Administration (FDA) but is allowed to be administered to people for research purposes.

What is a Placebo?

A placebo is often similar in appearance to the investigational medication but does not contain any active ingredients. In this study, the placebo does not contain active ingredients but is different in appearance from the investigational medication. Therefore, you will not be allowed to see the injection that you receive for the study so that you will not know what you receive.

What are my rights as a participant and what will happen if I decide not to participate?

Your participation in this study is voluntary. You can decide to stop at any time and you may still be treated at the facility. Your decision whether or not to take part in the study will not affect your current or future care at the facility.

Tell your study doctor if you are thinking about stopping or decide to stop. You should talk to the study doctor about leaving the study before you decide so that he/she can find out if you are having any side effects from study treatment, and he/she can tell you how to stop safely. Because this study only requires a single injection on Study Treatment Visit Day 1, it is not expected that there will be any harm to your well-being (for example, withdrawal symptoms) if you decide to stop. Another reason to tell the study doctor that you are thinking about stopping is so that he/she can talk to you about any other treatments, follow-up care, and/or testing that could be helpful to you.

If you decide to stop participating in this study, you will be asked to come back to the research site for an Early Termination Visit. This information is important to make sure there are no lasting side effects from the investigational medication and to see if your disease got better, stayed the same, or got worse.

What are my responsibilities while participating in this study?

You are asked to follow, without exception, the rules and instructions listed within the Informed Consent for the study. If you do not follow these rules and instructions, you may be withdrawn from the study.

In order to provide maximum protection for your health, the study will be under the direct supervision of the study doctor and will be conducted by trained personnel. You will need to provide all information about your current and past health (medical history) at the Screening Visit and at each Follow-Up Visit, including participation in any other research studies. This information is needed to protect your health.

If you have a personal doctor, it is strongly recommended that you inform him/her of your participation in this research study.
