Methods: Healthy females (14–45 years old) with moderate facial acne were randomized to 3 mg drsp/20 μg EE 24/4 (n=270) or placebo (n=268) for six cycles. The secondary efficacy variables measured included change from baseline to endpoint (cycle 6) in individual lesion count for nodules, papules, pustules, open and closed comedones.
Results: There were significantly greater reductions in individual lesion counts from baseline to endpoint in the 3 mg drsp/20 μg EE group than in the placebo group (P<0.05 from parametric model).
Conclusion: The 3 mg drsp/20 μg EE COC administered in a 24/4 regimen significantly reduced acne lesions.
