Clinuvel Pharmaceuticals (ASX:CUV) successfully administered Scenesse, or afamelanotide, to a nine-year-old patient in Switzerland with severe symptoms of erythropoietic protoporphyria, a type of genetic disorder characterized by a deficiency in the ferrochelatase enzyme, according to a Friday filing with the Australian bourse.
Scenesse is approved for the prevention of phototoxicity, or sensitivity to light after exposure to a chemical substance, in adult patients with erythropoietic protoporphyria, the filing said.
Following a 2024 pharmacokinetic study that identified no safety concerns in all patients, Clinuvel intends to seek a label update approval in Europe later this year to cover adolescents, the filing added.
The company's shares slipped 2% in recent Friday trade.
