Erythropoietic protoporphyria (EPP) is characterised by intense phototoxic reactions when exposed to visible light sources. These debilitating reactions have been described as akin to “lava flowing underneath the skin” and have a significant impact upon quality of life for those living with EPP.
A recent study asked EPP patients about the experience of their most recent phototoxic reaction. Adults reported an average pain score of 7.6 out of 10, and adolescents reported a score of 7.2, with symptoms typically lasting about five days before resolving.
CLINUVEL is committed to advancing care for EPP patients worldwide, helping them receive the treatment they urgently need to reduce the impact of phototoxic reactions and improve daily life.
