Summary
This study tested an experimental drug called MT-7117 in 102 adults with erythropoietic protoporphyria (EPP), a rare condition that causes severe pain from sunlight exposure. The goal was to see if the drug could increase the time people could spend in the sun without symptoms. Participants took either the drug or a placebo for 16 weeks, and researchers measured how long they could stay in sunlight before feeling pain.
