Experimental gene therapy targets rare immune disorder

NCT ID NCT01855685

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This trial tested a gene therapy for X-linked chronic granulomatous disease (X-CGD), a rare genetic disorder that leaves boys unable to fight off infections. The treatment involved taking the patient's own blood stem cells, adding a working copy of the faulty gene, and returning them to the body. The goal was to restore immune function and reduce severe infections and inflammation. Only 3 patients were enrolled before the study was terminated.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

gene therapy (lentiviral vector with GP91PHOX gene)

What this could lead to

If successful, this gene therapy could provide a long-term treatment option for X-CGD patients who lack a donor for bone marrow transplant, reducing severe infections and inflammation.

What could go wrong

This was a very early, small trial (only 3 participants) that was terminated, so results are limited. Gene therapy carries risks like immune reactions or the treatment not lasting.
