What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

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.
