FDA Approves Clinuvel’s Scenesse, the First Treatment for a Rare Genetic Metabolic Disorder that Causes Light Intolerance

MELBOURNE, Australia, Oct. 08, 2019 (GLOBE NEWSWIRE) — The US Food and Drug Administration (FDA) has approved a new drug as the first ever treatment for a rare genetic metabolic disorder which causes absolute intolerance to light. SCENESSE® (afamelanotide 16mg), the first drug developed by Australian biopharmaceutical company CLINUVEL, has been approved to “increase pain free light exposure in adult patients with a history of phototoxic reactions from erythropoietic protoporphyria (EPP)”.

“Today is a memorable day and victory for EPP patients, their families, and the global medical community who have all supported the development and US approval of the first ever treatment for this debilitating condition and the world’s first systemic photo protective drug,” CLINUVEL’s Chief Scientific Officer, Dr Dennis Wright said.

“EPP patients are born with the disease and need to avoid all sources of light exposure, including sunlight throughout their life, or risk incapacitating burns. SCENESSE® is a novel drug and formulation, developed by CLINUVEL to provide photo protection for EPP patients, enabling patients to expose to light, providing them a freedom they never had,” Dr Wright said.

EPP is an inherited metabolic disorder of the heme biosynthesis pathway which causes lifelong phototoxicity due to the accumulation and storage of the compound protoporphyrin IX (PPIX) in the blood and tissues. When exposed to visible light and near-visible ultraviolet radiation, PPIX is activated, causing damage to surrounding tissue. Patients report they experience excruciating burning pain underneath their skin which can last days or weeks and forces them to avoid all further exposure to light. It is estimated that there are 5,000 to 10,000 EPP patients worldwide.

In 2014, SCENESSE® was approved by the European Medicines Agency for EPP. The drug binds to the melanocortin-1 receptor on skin cells and sets in motion a cascade of cellular events, one of which is the activation of the pigment melanin to provide a physical barrier to visible and invisible light in EPP patients. The drug is administered as a 16mg controlled-release injectable implant, designed to provide protection for up to 60 days.

“On this day, there are many professionals, patient organisations and stakeholders to be grateful to, but I should not forget the FDA’s Divisional Director who led the review of SCENESSE® in EPP,” CLINUVEL’s Chief Executive Officer, Dr Philippe Wolgen said. “Our team is granted very little time to celebrate and now needs to shift its focus to facilitating drug product access for US EPP patients.”
