New pill shows promise for rare skin cancer in early trial

NCT ID NCT05944562

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This early-phase trial tests a new drug called tulmimetostat (DZR123) in 24 people with advanced mycosis fungoides or Sézary syndrome, rare types of skin lymphoma. Participants must have tried at least one prior treatment. The study aims to see if the drug is safe and tolerable, and whether it can help control the disease. Because it is a Phase 1 trial, the main focus is on safety and finding the right dose, not yet on proving effectiveness.
