NCT ID NCT07190001

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

Summary

This early-phase trial will test a single dose of a new drug called YOLT-204 in 18 children and teens with transfusion-dependent β-thalassemia or sickle cell disease. The goal is to see if it is safe and can raise fetal hemoglobin levels enough to reduce the need for blood transfusions. Participants will be followed for at least a year, with long-term monitoring up to 15 years.
