Status Completed

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of diclofenac diethylamine 2.32 percent (%) gel applied twice daily versus diclofenac diethylamine 1.16% gel applied four times daily for 7 days in participants with acute ankle sprain.

Clinical Trial Description

This study is a Phase III, randomized, double blind, multi-center, active controlled, 2-treatment arm, parallel group, non-inferiority study to evaluate the efficacy and safety of diclofenac diethylamine 2.32% gel applied twice daily versus diclofenac diethylamine 1.16% gel applied four times daily for 7 days in participants with acute ankle sprain. The participants who experience an acute Grade I -II ankle sprain within the past 24 hours, and pain on movement of at least 50 millimeter (mm) on a 100 mm visual analogue scale (VAS) and who will meet all inclusion and exclusion criteria will be randomized in a 1:1 ratio, immediately post injury. All participants will receive 4 tubes of study drug, for treatment in morning, noon, late afternoon, and late evening, respectively. The very first dose of study drug will be applied at the study center. The participants will be instructed to apply the gel topically with the finger tips for approximately 1 minute in the morning, at noon, late afternoon, and late evening for 7 days. Each tube will be labeled for use at one of these 4 times. After the randomization visit (Visit 1/baseline visit- Day 1), participants will return to the study site for post baseline visits- Visit 2 (Day 3), Visit 3 (Day 5), and Visit 4 (Day 8 +/- 1 d) to complete efficacy and safety assessments. Baseline safety laboratory test blood samples will be taken at Visit 1. End of study safety laboratory tests will be performed at Visit 4, or in case of early termination on the day of termination. In addition, the participants (ex-clinic) will assess pain intensity and pain relief at frequent intervals on Day 1 and then at each study drug application throughout the rest of the study. ;
