Clascoterone: A Novel Topical Androgen Receptor Inhibitor for the Treatment of Acne.

Abstract

To review the efficacy and safety of clascoterone 1% cream for the treatment of acne vulgaris in patients 12 years of age and older. A literature search through PubMed, MEDLINE, and ClinicalTrials.gov was conducted using the following keywords: clascoterone, cream, acne, and CB-03-01. Articles published between 2004 and 2020 were included in this review. Preclinical and clinical studies describing the efficacy and safety of topical clascoterone cream were included. Early preclinical studies demonstrated that clascoterone exhibits local antiandrogenic effects without any systemic effects. Phase 2 and 3 trials demonstrated a statistically significant reduction in inflammatory and noninflammatory lesions and mild erythema with clascoterone use. Long-term studies confirmed the favorable safety profile of the drug in subjects for up to 9 months of use, with erythema being the most common treatment-emergent local skin reaction. Pharmacological treatment options for acne vulgaris include topical and systemic agents. Systemic antiandrogen medications are associated with adverse effects and should be avoided in pregnancy and male patients. Clascoterone is a novel topical antiandrogen drug with no systemic adverse effects. This drug provides prescribers with an appealing treatment option for male and female patients 12 years of age and older, who are not candidates for systemic drugs because of contraindications or adverse effects or who have failed other topical therapies. Clascoterone, a novel topical androgen receptor inhibitor, is a safe and effective treatment option for patients with acne vulgaris.
