About this study

Official title: A Phase Ib/2 Trial of Fludarabine/Melphalan/Total Body Irradiation With Post Transplant Cyclophosphamide as Graft Versus Host Disease Prophylaxis in Matched-Related and Matched-Unrelated Allogeneic Hematopoietic Cell Transplantation

This phase Ib/2 trial studies how well chemotherapy, total body irradiation, and post-transplant cyclophosphamide work in reducing rates of graft versus host disease in patients with hematologic malignancies undergoing a donor stem cell transplant. Drugs used in the chemotherapy, such as fludarabine phosphate and melphalan hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells. When the healthy stem cells from a donor are infused into the patient, they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells (called graft versus host disease). Giving cyclophosphamide after the transplant may stop this from happening.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the cumulative incidence of extensive chronic graft versus host disease (GVHD) at 1 year after transplantation utilizing the novel conditioning/GVHD prophylactic regimen for patients undergoing allogeneic hematopoietic cell transplantation, in patients who do not progress before day 100.

SECONDARY OBJECTIVES:

  1. To evaluate clinical response, engraftment rate, progression-free survival (PFS) at one year and, overall survival (OS).

II. To determine the cumulative incidence of relapse. III. To evaluate the day 100 transplant-related mortality rate. IV. To determine the cumulative incidence of grade III-IV acute GVHD.

OUTLINE: This is a dose-escalation study of melphalan hydrochloride.

CONDITIONING REGIMEN: Patients receive fludarabine phosphate intravenously (IV) over 30 minutes on days -5 to -2 and melphalan hydrochloride IV over 30 minutes on day -2. Patients undergo total body irradiation (TBI) on day -1.

STEM CELL INFUSION: Patients undergo allogeneic hematopoietic stem cell transplant on day 0.

GVHD PROPHYLAXIS REGIMEN: Patients receive cyclophosphamide IV over 2 hours on days 3-4, mycophenolate mofetil IV over 2 hours on days 5-35, and tacrolimus IV and then orally (PO) once tolerated on days 5-180 with a taper beginning on day 100.

After completion of study treatment, patients are followed up for 12 months and then annually thereafter.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Allogeneic Hematopoietic Stem Cell Transplantation, Cyclophosphamide and Fludarabine Phosphate in people with Acute Myeloid Leukemia in Remission and Adult Acute Lymphoblastic Leukemia in Complete Remission, run by Roswell Park Cancer Institute 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 30 inclusion and 8 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: under way, not looking for participants, as of the sponsor's last update on 14 Apr 2026. 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 14 Apr 2026). 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?

Extensive Chronic Graft Versus Host Disease (GVHD) (time frame: Up to 365 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03192397.

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 14 Apr 2026.
