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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests a new gene therapy for children with a severe immune disorder called Artemis-SCID, where the body cannot fight infections. Doctors take the child's own blood stem cells, fix the faulty gene in a lab, and put the corrected cells back. The goal is to rebuild a working immune system without needing a bone marrow donor or lifelong medication.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient to 47 months * SCID patients with confirmed biallelic mutations in the Artemis (DCLRE1C) gene even in the case of leaky forms characterised by a residual activity * Absence of an HLA genoidentical donor or without rapidly available HLA-compatible unrelated donor (within six weeks of diagnosis) * The patient can be treated by gene therapy without delay in case of active life threatening infections compromising the short-term prognosis and for which the delay in finding a phenoidentical donor is incompatible with the patient's condition of health. Active life threatening infections are defined as: viral respiratory infection, CMV infection, adenovirus infection, disseminated BCGitis or other infections grade ≥ 4 according to CTCAE scale * Beneficiary of a social security scheme * Parental, guardian's patient signed informed consent. Exclusion Criteria * Unwillingness to return for follow-up during the first 2 years study and the long term follow-up * HIV-1 or 2 or HTLV1 infections * Hypersensitivity to G-CSF, busulfan or Fludarabine * Unable to tolerate general anesthesia and/or marrow harvest or peripheral blood stem cell collection (apheresis) or insertion of central venous catheter.
