Management of Truncal Acne With Oral Sarecycline: Pooled Results from Two Phase-3 Clinical Trials.

BACKGROUND

Acne vulgaris is a common skin disease that affects the face, chest, and back. While truncal acne is present in at least 50% of patients, clinical studies have focused predominantly on facial acne.1,2 Few treatments to date have been evaluated for truncal acne. Sarecycline is a narrow-spectrum, third-generation, tetracycline-class oral drug approved for the treatment of acne. Pivotal phase-3 studies show that sarecycline is safe, well-tolerated, and effective treatment for moderate to severe acne vulgaris.

METHOD

Pooled analysis was performed for truncal acne results with sarecycline from the two phase 3 studies. Investigator Global Assessment (IGA) success was evaluated at weeks 3, 6, 9, and 12.

RESULTS

Chest IGA success rate were significantly greater with sarecycline versus placebo at weeks 3 (11.84% vs 7.71%, respectively; P=0.0192), 6 (18.81% vs 14.03%, respectively; P=0.0390), and 12 (33.42% vs 20.77%, respectively; P<0.0001). Back IGA success rate was also significantly greater with sarecycline versus placebo group at weeks 3 (12.13% vs 7.04%, respectively; P=0.0023), 6 (18.42% vs 14.34%, respectively; P=0.0412), 9 (29.05% vs 19.88%, respectively; P=0.0004) and 12 (33.07% vs 21.91%, respectively; P<0.0001)Conclusion: Sarecycline efficacy for truncal acne was observed within 3 weeks after treatment, supporting sarecycline as an optimal choice for oral treatment of moderate to severe truncal acne.
