Awards & highlights

Summary

This trial will test whether using gene therapy to change the expression of a particular gene will lead to increased fetal hemoglobin production in people with sickle cell disease.

Who is the study for?

This trial is for people aged 3-40 with severe Sickle Cell Disease (SCD) who've had multiple pain events, acute chest syndrome, or need chronic transfusions. They must have tried hydroxyurea without success and can't have a matching bone marrow donor. Participants should be in stable health otherwise and willing to follow up for 15 years.

What is being tested?

The trial tests gene therapy using the patient's own modified blood stem cells to treat SCD. It involves a single infusion of these engineered cells aiming to increase fetal hemoglobin production which could potentially cure SCD.

What are the potential side effects?

Potential side effects may include reactions similar to those experienced during bone marrow transplants such as infection risk due to immune suppression from chemotherapy, discomfort at the infusion site, and possible organ inflammation.
