Common heartburn drug tested as potential lifeline for rare, painful sunlight disorder

NCT ID NCT05020184

Summary

This study tested whether cimetidine, a common heartburn medication, could help people with rare genetic disorders (EPP and XLP) that cause severe, painful reactions to sunlight. In this Phase 2 trial, 26 participants took either cimetidine or a placebo for three months to see if it reduced the harmful light-sensitive substance in their blood and improved their ability to tolerate light. The goal was to find a safe, repurposed drug to control this lifelong condition and prevent serious complications like liver damage.
