Randomized Controlled Trial Multicenter Study Comparative Study
A Phase 2b, Randomized, Double-Blind Vehicle Controlled, Dose Escalation Study Evaluating Clascoterone 0.1%, 0.5%, and 1% Topical Cream in Subjects With Facial Acne
Androgens play a key role in acne pathogenesis in both males and females. Clascoterone (CB-03-01, Cortexolone 17α propionate) cream is a topical anti-androgen under investigation for the treatment of acne. The results from a phase 2b dose escalating study are discussed. Methods: Primary objective: to compare the safety and efficacy of topical creams containing clascoterone 0.1% (twice daily [BID]), 0.5% (BID), or 1% (daily [QD] or BID) versus vehicle (QD or BID) in male and female subjects ≥12 years with facial acne vulgaris. ⋯ Erythema was the most prevalent LSR; 36.8% had at least minimal erythema at some point during the study. Conclusions: All clascoterone cream concentrations were well tolerated with no clinically relevant safety issues noted. Clascoterone 1% BID treatment had the most favorable results and was selected as the best candidate for further clinical study and development. Two Phase 3 investigations of clascoterone topical cream, 1% for the treatment of moderate-to-severe acne vulgaris in individuals ≥9 years recently concluded. J Drugs Dermatol. 2019;18(6):570-575.

Review Case Reports
Arterial Occlusion and Necrosis Following Hyaluronic Acid Injection and a Review of the Literature
With the rising popularity of fillers for facial rejuvenation coupled with the paucity of regulations on credentialing of qualified injectors, the number of filler related complications is increasing. Although the majority of complications are mild, vascular occlusion is the most feared and dangerous. ⋯ Physicians who perform filler injections should also be able to promptly recognize complications and manage them. We report a case of vascular occlusion successfully managed using high dose hyaluronidase and provide a review of the literature including incidence, management, and techniques to prevent vascular complications.
