Welcome to the TANGO study!

TANGO study overview

Arthritis affects millions of people worldwide. The most common kind of arthritis — called osteoarthritis — happens when the cartilage that protects the ends of your bones wears down. This leads to symptoms like pain and stiffness. Osteoarthritis can affect any joint in your body, including knees and hips.

In the TANGO study, researchers are working to see if a new medication may help people with osteoarthritis in the future.

Study medication

This study is testing an investigational medication called tanezumab to see if it may provide pain relief for people with osteoarthritis. "Investigational" is another way of saying that tanezumab has not been approved for use by the public. The study medication and all study procedures and clinic visits will be provided to you at no charge throughout your participation in the study.
