Conditions: Acne Vulgaris
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 40
Healthy volunteers: no

Brief summary:
A single-blind (investigator-blinded), randomized, parallel group, single center study to evaluate the tolerability and efficacy of combination therapy with Duac Gel / 0.1% Tazorac Cream and Acanya Gel / 0.1% Tazorac Cream for the treatment of facial acne vulgaris.

Detailed description:
This is a single-blind (investigator-blinded), randomized, parallel group, single center study to evaluate the tolerability and efficacy of combination therapy with Duac Gel/Tazorac Cream and Acanya Gel/Tazorac Cream for the treatment of facial acne vulgaris. Approximately 40 male and female subjects will be enrolled (20 per study group).

Subjects will participate in the study for 12 weeks; visits will be scheduled at baseline and at weeks 1, 2, 4, 8, and 12 (total of 6 visits). Eligible subjects will be randomized at baseline to 1 of the 2 study groups in a 1:1 ratio (Duac Gel/Tazorac Cream to Acanya Gel/Tazorac Cream). Subjects will apply either Duac Gel or Acanya Gel to the face each morning and apply Tazorac Cream to the face each evening.

Tolerability will be evaluated through subject assessments of burning/stinging, itching, and oiliness and through investigator assessments of peeling, erythema, and dryness. In addition, subjects will evaluate their overall skin comfort and record the usage of moisturizer and sunscreen, if needed. Efficacy will be assessed through lesion counts (total, inflammatory and noninflammatory) and ISGA. Safety will be assessed by evaluating adverse events (AEs), concomitant medication use, and withdrawals from the study.

This is an investigator-blinded study; therefore, subjects and study-center staff will not be blinded to study treatment allocation. Subjects (and parents or legal guardians) and study-center staff will be instructed not to reveal study product allocation to the investigator.
