New drug cocktail aims to boost stem cell harvest for rare immune disease
NCT ID NCT03055247
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This phase II trial tests whether a combination of ibuprofen, G-CSF, and plerixafor can safely and effectively mobilize stem cells from the bone marrow into the blood in people with X-linked chronic granulomatous disease (X-CGD). Only 3 adults aged 18-45 are being enrolled. The goal is to collect enough stem cells for future gene therapy, which could help control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ibuprofen, G-CSF, and Plerixafor
- What this could lead to
- If successful, this could improve stem cell collection for gene therapy in X-CGD, potentially enabling a one-time treatment that reduces infections.
- What could go wrong
- This is a very small early-phase trial with only 3 participants, so results may not apply broadly. The drug combination may cause side effects like bone pain or allergic reactions.
