Lainate, Italy – August 20, 2019 – Cassiopea SpA (SIX: SKIN), a specialty pharmaceutical company that develops and markets prescription drugs with new treatments (MOAs) to treat previously unresolved and major dermatological conditions, has filed a new drug application with the US Food and Drug Administration (FDA). NDA) for approval of Clascoteron 1% acne treatment cream.

Clascoteron 1% cream is being developed as a new topical androgen receptor inhibitor for the treatment of acne. Clascoterone is a locally administered small molecule that penetrates the skin to reach the androgen receptors of the sebaceous glands. It will be the first effective and safe androgen therapy that has no systemic side effects.

Clascoterone 1% cream targets androgen receptors at the site of use and inhibits the local effects of dihydrotestosterone (DHT), a major cause of acne treatment. Laboratory studies show that clocoteron inhibits the production of lipids by oil-producing cells (sebocytes) and reduces proinflammatory cytokines, which are considered to be mediated and influenced by androgens. Consequently, clusterherons are disrupted mechanisms that trigger the development of acne lesions. Unlike oral hormone therapies for the treatment of acne, Clascoteron can be used by men and women.

It has been a long time since there has been a new molecule for acne treatment, especially considering that topical treatment targets androgen receptors directly to the sebocytes to reduce lipid production and inflammation. "said Dr. Lawrence Eichenfield, Head of Pediatric and Adolescent Dermatology at Rady Children's Hospital, San Diego." Dermatologists now have another option to treat their acne patients, which is invaluable. "

Cassiopea released the results of two key phase III clinical trials of Clascoterone 1% cream last year, which showed statistically significant improvements in all primary endpoints. Clinical trials have found no significant adverse reactions resulting from treatment; if local skin reactions were found to be similar to the vehicle and were classified predominantly as mild. The safety results, released earlier this year, were confirmed in an open-label safety study over a one-year treatment period. The face was treated, as was the trunk. The prolonged duration and increased scope of administration did not increase the incidence of significant adverse reactions.

"If approved, Clascoteron 1% Cream will be the first approved new mechanism of action for the treatment of acne in nearly 40 years, providing a new and effective therapeutic alternative to dermatologists and patients," said Diana Harbort, director of Cassiope. "We are focused on treating urgent skin diseases that can leave not only physical but also mental scars. Innovation is so important, and we are committed to finding a way to treat acne, which is the cause of the disease."
