About

The purpose of this study is to determine the safety and effectiveness of micronized dehydrated human amnion chorion membrane as compared to the 0.9% Sodium Chloride Injection, USP placebo control for the treatment of knee osteoarthritis

Full description

Each subject will receive 1 injection (micronized dHACM or placebo) and be evaluated for efficacy and safety during a 12-month observation period. A second injection (open-label access to micronized dHACM) will be offered to all subjects at the 180-day, 270-day, and 365-day time points, it may only be used once. Blinding for the first injection treatment allocation will be maintained until the end of the study.

Subjects who receive the open-label access treatment will continue to be followed for 180 days after this second injection, regardless of the time at which treatment was received.
