ISTANBUL, TURKEY – Azelaic acid 15% gel constitutes an effective and well-tolerated treatment option for women with adult acne, according to the findings of an investigator-blinded, 9-month, randomized clinical trial.
The results showed azelaic acid 15% gel was similar in effectiveness to adapalene 0.1% gel, a widely prescribed treatment for this common condition, Dr. Anja Thielitz reported at the annual congress of the European Academy of Dermatology and Venereology.
However, azelaic acid 15% gel had a clear advantage in terms of tolerability. Median scores for skin redness, dryness, and scaling were significantly lower in the azelaic acid–treated group, added Dr. Thielitz of Otto von Guericke University in Magdeburg, Germany.
The single-center study involved 55 women aged 18-45 years, all with mild to moderate adult acne. They were randomized to one of three study arms: azelaic acid 15% gel twice daily for 9 months; adapalene 0.1% gel once daily, or 3 months of twice-daily azelaic acid 15% gel followed by 6 months of observation with no treatment.
Inflammatory and noninflammatory acne lesion counts, microcomedones, acne grading scale scores, and Dermatology Life Quality Index scores improved similarly in all three groups after 3 months. For example, median total lesion counts decreased from approximately 50 to 20, and median scores on the Leeds revised acne grading system dropped from 4 to roughly 2.5. Similar degrees of additional improvement were seen during months 4-9 in the two groups who remained on active treatment.
In contrast, some backsliding – although less than Dr. Thielitz had anticipated occurred during the untreated observation period among patients who halted the azelaic acid 15% gel after 3 months. By month 9, their total lesion count was 31% greater than the group that stayed on the topical therapy for the full 9 months.
Of note, azelaic acid 15% gel is technically an off-label therapy for adult female acne. The medication’s approved indication is in treating mild to moderate rosacea.
Dr. Thielitz reported having no financial conflicts in this investigator-initiated randomized trial.
