NCT ID NCT05417971

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests a reduced-intensity stem cell transplant for people with blood cancers like leukemia or lymphoma. The approach uses lower doses of chemotherapy and radiation before a half-matched donor transplant. Researchers hope this gentler method will help the body accept the new cells while lowering the chance of the cancer coming back. The study is currently recruiting 20 participants.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Fludarabine and total body irradiation followed by stem cell transplant
What this could lead to
If successful, this could offer a safer transplant option for people with blood cancers, reducing the risk of graft rejection and relapse.
What could go wrong
This is a small, early-phase trial with only 20 participants. The reduced-intensity approach may still carry risks like infection, graft failure, or relapse.

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: * Availability of 3/6 - 5/6 matched related donor with a negative HLA-cross match in the host vs. graft direction willing to donate peripheral blood stem cells * KPS \>/= 70% * Hematologic malignancy requiring allogeneic transplantation, with a predicted high risk of relapse following non-myeloablative, low intensity conditioning. Exclusion Criteria: * Poor cardiac function (LVEF \<45%) * Poor pulmonary function (FEV, FVC, DLCO \<60%) * Poor liver function (bilirubin \>/= 2.5mg/dL; AST or ALT \>3xULN) * Poor renal function (creatinine clearance \<40mL/min) * HIV-positive; active HepB or HepC * Uncontrolled infection * Pregnant female or not able to practice adequate contraception * Debilitating medical or psychiatric illness which would preclude their giving informed consent
