- Registration Number
- NCT03615768
- Lead Sponsor
- Lee's Pharmaceutical Limited
- Brief Summary
This is a study to see if Adapalene-Clindamycin Combination Gel is effective and safe in the treatment of acne vulgaris, compared to adapalene gel alone and clindamycin gel alone. Adapalene and clindamycin have been reported to have a better effect in acne treatment when used together. This new formulation is also easier to use as it combines two products into a single gel and only needs to be used once a day.
