  • Submission to EMA is supported and based on the efficacy and safety evidence gathered in two identical, randomized, placebo-controlled phase III clinical trials enrolling >1,400 patients with acne vulgaris.
  • The trials were successful and Winlevi® met the three co-primary endpoints, demonstrating treatment success in Investigator’s Global Assessment (IGA) and reductions in acne inflammatory and non-inflammatory lesion count.
  • Winlevi® was well tolerated and showed a benign safety profile.
  • FDA approved Winlevi® in 2020, as a novel drug with a unique mechanism of action for the topical treatment of acne in patients aged 12 years and older.
  • This filing marks a significant milestone in pipeline progression, as approval will open the substantial EU market to already selected, high-standing partners.
