Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 8-16 with clinically diagnosed transfusion-dependent β-thalassemia major.

Probably not a fit

Patients who have received gene therapy or allogeneic hematopoietic stem cell transplantation in the past may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This open-label study aims to assess the safety and efficacy of β-globin restored autologous hematopoietic stem cells in patients with β-thalassemia major. Participants aged 8-16 will have their own hematopoietic stem cells collected and modified using the LentiHBBT87Q system to restore β-globin expression. After a conditioning regimen, these modified cells will be reinfused into the patients, who will be monitored for two years to evaluate treatment outcomes.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients with β-thalassemia major by reducing their dependence on blood transfusions.

How similar studies have gone: While gene therapy approaches for β-thalassemia are being explored, this specific method using autologous stem cells with β-globin restoration is relatively novel.
