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 Results may not be published yet.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.

Summary

This phase 2 trial tests a reduced-intensity chemotherapy regimen (fludarabine, busulfan, melphalan) before stem cell transplant in 61 patients aged 55 and older with myeloid cancers like AML, MDS, or CMML. The goal is to see if this gentler approach can improve disease-free survival while reducing side effects. Participants must have a matched or haploidentical donor and be in remission or early disease stages.

What this could mean

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

Active substance
MBF-RIC (fludarabine, busulfan, melphalan)
What this could lead to
If successful, this milder chemo regimen could make stem cell transplants safer and more effective for older adults with myeloid cancers, potentially improving long-term survival without relapse.
What could go wrong
This is a small, early-phase study (61 participants) without a comparison group. The regimen may still cause serious side effects, and results may not apply to all patients or donors.
