To evaluate the efficacy and tolerability of diclofenac diethylamine 1.16% w/w gel in patients with acute localised muscle or joint injuries

Phase 3

Completed

• Conditions: Pain, unspecified,

• Registration Number: CTRI/2023/01/049202
• Lead Sponsor: JAMP Pharma Corporation

Brief Summary

This study is Non-inferiority, Randomized, Double blind, Clinical Trial for Comparing the Efficacy and Tolerability of Diclofenac diethylamine 1.16% w/w gel of JAMP Pharma vs Voltaren Emulgel® (Diclofenac diethylamine 1.16% w/w) of GlaxoSmithKline Consumer Healthcare Inc., Canada in Patients with acute localized muscle or jointinjuries. Sample size is 255: 102 patients for Test, 102 for Reference and 51 for Placebo, where the primary objective is to confirm the clinical non-inferiority of the generic Diclofenac diethylamine 1.16% w/w gel/JAMP Pharma (Test) with the marketed Voltaren Emulgel/GSK (Reference) in patients with acute localized muscle or joint injuries on relief of pain as assessed by the patient by means of a 100 mm visual analogue scale (VAS) (scoring range 0–100) after seven days of treatment and secondary objective is to confirm the superiority of Test and Reference to Placebo in pain after seven days of treatment, to estimate the relief of pain of Test product compared to Reference during the treatment period and to demonstrate the tolerability of Test and Reference products.

Primary Outcome Measures

Name	Time	Method
To confirm the clinical non-inferiority of the generic Diclofenac diethylamine 1.16% w/w gel/JAMP Pharma (Test) with the marketed Voltaren Emulgel/GSK (Reference) in patients with acute localized muscle or joint injuries on relief of pain as assessed by the patient by means of a 100 mm visual analogue scale (VAS) (scoring range 0–100) after seven days of treatment	Day 0 (Baseline) & Day 7 (End of treatment)

Secondary Outcome Measures

Name	Time	Method
