Is this trial a fit for you?

Likely a good fit

Adults 18–45 with genetically confirmed X‑CGD who have good performance status, adequate organ function, and no prior bone marrow transplant or gene therapy are ideal candidates.

Probably not a fit

Patients with prior transplantation or gene therapy, active infections, significant organ dysfunction, thrombophilic history, or contraindications to NSAIDs, G‑CSF, or plerixafor are unlikely to benefit or are excluded.

What this trial studies

This phase II exploratory trial tests whether combining ibuprofen with standard G‑CSF and plerixafor mobilization improves collection of hematopoietic stem and progenitor cells (HSPCs) in adults with X‑CGD. Participants receive G‑CSF, plerixafor, and a short course of ibuprofen before leukapheresis, with monitoring of safety and stem cell yield. The rationale is that chronic inflammation in X‑CGD may impair HSPC mobilization and that a non‑steroidal anti‑inflammatory could reduce inflammation and increase harvest. If a synergistic effect is seen, the regimen could be used in future gene therapy protocols for X‑CGD.

Why it matters

Potential benefit: If successful, the regimen could enable reliable collection of enough stem cells to make gene therapy options feasible for more people with X‑CGD.

How similar studies have gone: G‑CSF plus plerixafor is an established method for HSPC mobilization in gene therapy programs, but adding ibuprofen for X‑CGD patients is a novel approach with limited prior evidence.
