NCT ID NCT00092235

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 Results may not be published yet.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

Summary

This study follows 650 people with chronic graft-versus-host disease (cGVHD), a complication after stem cell transplants. Researchers aim to track the disease over time, identify biological markers, and improve how it is diagnosed and managed. Participants undergo regular check-ups and tests to help doctors better understand and treat this condition.

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: 1. Any patient age 1 and older referred by the primary transplant physician for the evaluation of chronic graft-versus-host disease independently of age or underlying diagnosis 2. Patient or the patient's legal representative is able and willing to provide consent. EXCLUSION CRITERIA: 1. Significant medical condition or any other significant circumstance that could in the PIs assessment affect the patient's ability to tolerate, comply, or complete the study 2. Patients who in the PIs assessment have a life expectancy \<3 months. Note: Because it is not always possible to make a clear clinical distinction between acute and chronic GVHD, patients with acute GVHD are not a-priori excluded until the possibility of chronic GVHD is reliably excluded on the basis of the clinical assessments in the cGVHD clinic. 3. Pregnant women are excluded from this study because multiple tests would need to be excluded for safety of the patient and the fetus. Inclusion Criteria for control subjects without cGVHD: * Age 1 and older * Patient has undergone Allo-HSCT * Patient or the patient's parent/guardian is able and willing to provide consent Exclusion Criteria for control subjects without cGVHD: * Active GVHD * In the previous three months have received systemic immunosuppressant therapy for the treatment of GVHD * In the previous three months have received therapy for malignancy
