First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This completed Phase 3 trial tested a drug called MR13A9 in 178 adults on hemodialysis who suffer from severe itching (uremic pruritus). The study compared MR13A9 to a placebo to see if it reduces itch intensity, measured by a daily 0-10 rating scale. If successful, MR13A9 could become a new treatment option for this distressing symptom.
