Trial summary

The investigators hypothesize that long-term disease-free survival (DFS) in patients with JMML can be achieved with a treatment of busulfan (BU), cyclophosphamide (CY) and melphalan (L-PAM) followed by hematopoietic cell transplantation (HCT). Read more about this study

About this study

Official title: Hematopoietic Cell Transplantation in Children With Juvenile Myelomonocytic Leukemia

The investigators hypothesize that long-term disease-free survival (DFS) in patients with JMML can be achieved with a treatment of busulfan (BU), cyclophosphamide (CY) and melphalan (L-PAM) followed by hematopoietic cell transplantation (HCT).

Read the detailed description

Prior to transplantation, subjects will receive BUSULFAN via the central venous line, six times a day for four days, CYCLOPHOSPHAMIDE via the central venous line once a day for two days, and MELPHALAN via the central venous line for one day. Busulfan, cyclophosphamide, and melphalan are given to destroy the subject's leukemia. As well, these drugs will destroy the subject's own immune system to help ensure the new bone marrow takes and grows after transplantation.

On the day of transplantation, bone marrow or umbilical cord blood from the donor will arrive to the bone marrow transplant unit and be transfused via venous line. These new cells will replace the subject's bone marrow.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Stem Cell Transplant and Preparative Regimen in people with Juvenile Myelomonocytic Leukemia, run by Masonic Cancer Center, University of Minnesota at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Nov 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Determine Probability of Long-term Disease Free Survival in JMML (time frame: at 1 year after transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Nov 2023.
