Evaluation of Clinical Endpoints of Two Diclofenac Sodium Gel 1%
A Double-Blind, Randomized, Placebo-Controlled, Parallel Group, Multi-Site Study to Evaluate the Clinical Equivalence of Diclofenac Sodium 1% Gel (Anchen Pharmaceuticals, Inc.) With Voltaren® Gel (Diclofenac Sodium Topical Gel) 1% (Novartis) in Patients With Osteoarthritis of the Knee
The objective of this study is to evaluate the clinical equivalence and safety of the Test formulation of diclofenac sodium topical gel 1% (Anchen Pharmaceuticals, Inc.) compared to the marketed formulation Voltaren® Gel (diclofenac sodium topical gel) 1% (Novartis) in patients with osteoarthritis of the knee.

Superiority of Test and Reference against Placebo in the Mean Change from baseline in the total WOMAC pain score.
Time Frame: Baseline and Week 4
|
The superiority of treatment over the placebo will be concluded if the treatment's mean change from baseline in the total WOMAC pain score is statistically significantly greater (p<0.05) than that of the placebo in the ANCOVA based on the treatment and placebo results. The superiority of Test and Reference treatments over the placebo will be evaluated identically in a separate ANCOVA. The analyses will be conducted in the mITT population. |
