About this study

Official title: Cyclophosphamide Plus Transplantation of Partially HLA-mismatched (Haploidentical), CD8+ T Cell-depleted Peripheral Blood Cells for Patients With Myelodysplastic Syndrome, Acute Myeloid Leukemia, Lymphoma, or Myeloproliferative Disorders

RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of abnormal blood cells, either by killing the cells or by stopping them from dividing. Giving cyclophosphamide together with donor lymphocytes that have been treated in the laboratory may be an effective treatment for myelodysplastic syndromes or myeloproliferative disorders.

PURPOSE: This clinical trial is studying the best dose of donor lymphocytes when given together with cyclophosphamide in treating patients with myelodysplastic syndromes or myeloproliferative disorders.

Read the detailed description

OBJECTIVES:

  • Determine the maximum tolerated dose of allogeneic CD8-positive T-cell-depleted, haploidentical donor lymphocytes when given after cyclophosphamide in patients with myelodysplastic syndromes or myeloproliferative disorders.

OUTLINE: Patients receive cyclophosphamide on days 1 and 2. Patients then undergo infusion of allogeneic T-cell depleted donor lymphocytes on day 3.

Cohorts of patients receive escalating doses of CD8-positive T-cell-depleted haploidentical donor lymphocytes until the maximum tolerated dose is determined.

PROJECTED ACCRUAL: A total of 44 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.

  • CyclophosphamideDrug

    Also called Cytoxan, Cy, CTX

    50 mg/kg/day intravenously (IV) on Days -2 and -1.

  • Donor T cellsBiological

    CD8-depleted T cells given IV on Day 0. Dose levels are as follows (all doses in cells/kg):

    Dose level 1: 1E5 CD4+ cells and less than 3.2E3 CD8+ cells Dose level 2: 1E6 CD4+ cells and less than 3.2E4 CD8+ cells Dose level 3: 1E7 CD4+ cells and less than 3.2E5 CD8+ cells Dose level 4: 5E7 CD4+ cells and less than 1.6E6 CD8+ cells

What is being measured

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

  1. Maximum tolerated dose of haploidentical donor lymphocytes

    Maximum dose in cells per kilogram that did not cause dose-limiting toxicity (defined as grade 3-5 non-hematologic toxicity, death within 60 days related to protocol treatment, aplasia related to treatment, or grade 3-4 graft-vs-host-disease).

    Measured: 60 days

Secondary outcomes (2)
  1. Disease response

    Percentage of participants who had a complete remission after protocol treatment.

    Measured: Up to 6 months

  2. Duration of response

    Median length of response (in months) of participants who had a complete remission after protocol treatment.

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Cyclophosphamide and Donor T cells in people with Leukemia and Myelodysplastic Syndromes, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins 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?

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: stopped early, as of the sponsor's last update on 20 Aug 2018. 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 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.

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

Are results available for this study?

The study was stopped early (reason given: Poor accrual). Results are not available in the source record.

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?

Maximum tolerated dose of haploidentical donor lymphocytes (time frame: 60 days). 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 20 Aug 2018; AzTrials last refreshed its copy on 6 Nov 2026.
