BACKGROUND:Topical tretinoin has been extensively studied in clinical trials, and its essential role in the treatment of acne vulgaris (acne) established through evidence-based guidelines. OBJECTIVE: To evaluate efficacy, safety, and tolerability of a novel tretinoin 0.05% lotion in moderate-to-severe acne in patients aged 9 years and older. METHODS: A total of 1640 patients, 9-58 years of age were randomized to receive tretinoin 0.05% lotion or vehicle in two double-blind, placebo-controlled 12-week, 2-arm, parallel group studies evaluating safety and efficacy (inflammatory and noninflammatory lesion counts and acne severity using Evaluator Global Severity Scores [EGSS]). In addition, patients completed a patient satisfaction survey (PSS), Acne-specific quality of life (QoL) questionnaire and assessed their facial skin for shininess/oiliness improvement. The data from these two independent studies were pooled and analyzed. RESULTS:Tretinoin 0.05% lotion demonstrated statistically significant superiority to vehicle in reducing inflammatory and noninflammatory lesion counts (both P less than .001) at week 12 and improving acne severity (P less than .001). At week 12, mean percent change in inflammatory and noninflammatory lesions were 52% and 46%, respectively. Treatment success (a 2-grade improvement in EGSS and 'clear' or 'almost clear' was reported in 18% of patients. Tretinoin 0.05% lotion also showed significantly greater benefits relative to vehicle control in terms of patient satisfaction (P less than .001) and acne-specific QoL domains. Tretinoin 0.05% lotion was very well tolerated with no substantive differences in cutaneous tolerability among treatment groups. No patients discontinued treatment because of adverse events. LIMITATIONS: Data from controlled studies may differ from clinical practice. CONCLUSIONS:Tretinoin 0.05% lotion provides statistically significant greater efficacy than vehicle with a highly favorable safety and tolerability profile in moderate-to-severe acne patients.
