The above mentioned clinical trial, conducted by LABRHA on 226 patients with knee OA and which compares the efficacy and tolerance of HAppyVisc® vs. Euflexxa®, has been very recently published in the well-known international journal The Knee (Impact Factor:1.446).
Results of this study show:
- HAppyVisc® was non-inferior to Euflexxa® for reducing pain and improving function
- There was a trend for a faster response with HAppyVisc® than Euflexxa® on pain
- HAppyVisc® was as well tolerated as Euflexxa®
- No severe adverse event related to HAppyVisc® was reported.
