Severe Combined Immunodeficiency study: AProArt-CD34 vs Busulfan

Official title Autologous Gene Therapy for Artemis-Deficient SCID

ClinicalTrials.gov ID: NCT03538899

What this study is testing

What is AProArt-CD34?

This is an investigational gene therapy being studied as a potential treatment for Artemis-deficient Severe Combined Immunodeficiency (ART-SCID). It is designed to work by adding a normal copy of the DCLRE1C gene into the patient's own stem cells to help them make a functioning immune system.

Also referred to as lentiviral gene therapy using AProArt.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study will see if adding a normal DCLRE1C gene to the patient’s stem cells is safe and can create a functioning immune system.
Who it's for
Children newly diagnosed with Artemis‑deficient severe combined immunodeficiency who have no suitable sibling donor.
What's involved
Participants will receive a chemotherapy drug (busulfan) to prepare their body, then an infusion of their own stem cells that have been modified with a virus to carry a normal DCLRE1C gene. They will have regular check‑ups and lab tests.
Time commitment
Follow‑up lasts up to 15 years with scheduled visits after the infusion.
