A novel Australian drug to protect patients who are intolerant of light and sunlight will begin trials in the US in April. The US Food and Drug Administration (FDA) has given clearance to Melbourne’s Clinuvel Pharmaceuticals to commence a Phase 2 study (CUV030) of its drug afamelanotide in up to 60 patients diagnosed with the rare light intolerance erythropoietic protoporphyria (EPP).
The six month study, to be conducted in medical centers in Alabama, California, New York, North Carolina, Texas and Utah, is the first therapeutic trial of afamelanotide in the US.
It’s estimated around 3,000 Americans are known to be afflicted with EPP, a disease characterized by intolerable pain: their skin blisters and burns when exposed to normal levels of light and sunlight. The disease is incurable and affects patients for life.
As a result, EPP patients spend most of their lives indoors and lead a secluded life. Sunscreens are of no use in this disease as they don’t block out visible light (in the blue spectrum), which is the cause of toxic reactions in EPP.
Clinuvel has spent over US$64 million the past 10 years developing afamelanotide as the world’s first photoprotective drug, which works to activate a barrier of pigmentation (melanin) between light and a person’s skin. The implantable drug, the size of a rice grain, is able to stimulate and increase skin pigmentation in fair- skin patients who are less protected from UV damage.
Afamelanotide has been administered to over 500 patients to date in clinical trials in Europe and Australia, with preliminary Phase III results showing good safety and first signs that EPP symptoms can be prevented.
