First seen Jan 11, 2026 · Last updated May 14, 2026 · Updated 19 times

Summary

This early-stage study tested a gene-edited stem cell treatment (OTQ923) in 4 people with severe sickle cell disease. The goal was to boost fetal hemoglobin to reduce painful crises and other complications. The trial was terminated early, so full results are limited, but it aimed to see if the treatment was safe and could help control the disease long-term.
