A multicenter, randomized, double-blind, parallel, three-arm, active- and placebo-controlled therapeutic equivalence for the comparison of clindamycin + tretinoin/Verisfield gel (1+0.025)% with Acnatac®/Meda gel [clindamycin + tretinoin (1+0.025)%] in the treatment of acne vulgaris
EU CTIS ID: 2024-518430-91-00
What this study is testing
To establish the therapeutic equivalence of topical treatment with clindamycin+tretinoin/Verisfield gel (Test product) and Acnatac®/Meda gel (Reference product) in the treatment of acne vulgaris by demonstrating that the two products are therapeutically equivalent and superior to the Placebo, through assessing the changes from Baseline in the facial inflammatory and non-inflammatory lesion counts at Week 12.
