Is this trial a fit for you?

Likely a good fit

Ideal candidates are Vietnamese patients aged 12 years or older with mild to moderate acne vulgaris who are already prescribed Klenzit-C as part of routine care.

Probably not a fit

Patients with severe acne or those unlikely to respond to topical therapy may not experience benefit.

What this trial studies

This is a Phase 4, open-label, multicenter, prospective study in Vietnam evaluating adapalene 0.1%/clindamycin 1% gel used as part of standard practice. About 360 participants will apply the gel once daily for 12 weeks, with visits at baseline and Weeks 2, 4, 8, and 12. The main focus is safety and tolerability, including local skin reactions, with additional observations on changes in inflammatory and non-inflammatory lesions. The study describes real-world use of the product and its clinical effectiveness in routine dermatology care.

Why it matters

Potential benefit: If successful, patients may experience clearer skin and fewer acne-related symptoms with a well-tolerated, single-product regimen.

How similar studies have gone: Previous studies combining retinoids with topical antibiotics have shown greater efficacy than monotherapy in acne treatment.
