About this study

Official title: A Study of a Reduced-Intensity Conditioning Regimen With Treosulfan and Fludarabine for Allogeneic Hematopoietic Cell Transplantation for Patients With Acute Leukemia

RATIONALE: Drugs used in chemotherapy, such as treosulfan and fludarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving treosulfan and fludarabine together with a donor bone marrow transplant or a peripheral stem cell transplant may be an effective treatment for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome.

PURPOSE: This phase II trial is studying giving treosulfan together with fludarabine to see how well it works in treating patients who are undergoing a donor stem cell transplant for acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndrome.

Read the detailed description

OBJECTIVES:

Primary Phase

  • Determine the best dose of treosulfan when administered with fludarabine as a reduced-intensity conditioning regimen followed by allogeneic hematopoietic stem cell transplantation, in terms of incidence of severe to fatal toxicity to major organ systems and incidence of graft failure, in patients with acute myeloid leukemia, lymphoblastic leukemia, or myelodysplastic syndrome.

Secondary Phase

  • Determine the safety of this regimen, in terms of incidence of grade II-IV acute and chronic graft-versus-host disease, in these patients.
  • Determine, preliminarily, the efficacy of this regimen, in terms of incidence of relapse, overall and disease-free survival, donor chimerism on days 28 and 100, and incidence of 200-day and 1-year nonrelapse mortality, in these patients.
  • Determine the pharmacokinetic and pharmacodynamic profile of treosulfan in patients treated with this regimen.

OUTLINE: This is a multicenter, dose-finding study of treosulfan.

  • Reduced-intensity conditioning: Patients receive treosulfan IV over 2 hours on days -6 to -4 and fludarabine IV over 30 minutes on days -6 to -2.

Cohorts of 5-10 patients receive escalating/de-escalating doses of treosulfan until the best dose is determined among the 3 pre-selected doses. The best dose is defined as the dose preceding that at which 4 of 10 patients experience dose-limiting toxicity.

  • Allogeneic hematopoietic cell transplantation (AHCT): Patients undergo allogeneic bone marrow or peripheral blood stem cell transplantation on day 0.

All male patients with acute lymphoblastic leukemia OR male patients with acute myeloid leukemia who have prior or current testicular involvement receive external-beam radiotherapy to the testicles before AHCT.

After completion of study treatment, patents are followed periodically.

PROJECTED ACCRUAL: A total of 60 patients will be accrued for this study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • fludarabineDrug

    30 mg/m2, IV for 5 days

  • treosulfanDrug

    12 or 14 g/m2, IV for 5 days

  • allogeneic blood or bone marrow transplantationProcedure or surgery

    bone marrow or peripheral blood stem cells

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Patients Experiencing Regimen-related Toxicity Events in Study Population

    Proportion of patients experiencing regimen-related toxicity to major organ systems from day minus 6 to day 28. Major organ systems: cardiac, bladder/renal, pulmonary, hepatic, neurologic and gastrointestinal

    Measured: 34 days and 2 years

  2. Number of Patients Experiencing Graft Failure

    Graft versus Host Disease (GVHD) is a frequent complication of allogeneic bone marrow transplant in which the engrafted donor cells attacks the patient's organs and tissue. Acute GVHD (aGVHD) usually occurs during the first three months following an allogeneic BMT. Chronic GVHD (cGVHD) usually develops after the third month post-transplant. Patients may experience one, both or neither.

    Measured: 42 days

  3. Incidence (Percent of Participants) With Nonrelapse Mortality (NRM) by Day 200 (Secondary Phase Only)

    NRM (Non relapse mortality) - death not attributed to the primary cancer.

    Measured: 200 days

Secondary outcomes (1)
  1. Number of Subjects Who Are Without Disease at One Year as Indicator of Disease Free Survival.

    Measured: One year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing fludarabine, treosulfan and allogeneic blood or bone marrow transplantation in people with Leukemia and Myelodysplastic Syndromes, run by OHSU Knight Cancer Institute at 3 sites 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?

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 1 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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 11 Feb 2011). 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?

Number of Patients Experiencing Regimen-related Toxicity Events in Study Population (time frame: 34 days and 2 years). The study lists 3 primary outcomes in all. 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 1 Jun 2012.
