Show all 9Show fewer
  • DONOR: A positive anti-donor cytotoxic crossmatch is an absolute donor exclusion; donors are excluded when preexisting immunoreactivity is identified that would jeopardize donor hematopoietic cell engraftment; this determination is based on the standard practice of the individual institution; the recommended procedure for patients with 10 of 10 HLA allele level (phenotypic) match is to obtain a panel reactive antibody (PRA) screens to class I and class II antigens for all patients before HCT; if the PRA shows > 10% activity, then flow cytometric or B and T cell cytotoxic cross matches should be obtained; the donor should be excluded if any of the cytotoxic cross match assays are positive; for those patients with an HLA Class I allele mismatch, flow cytometric or B and T cell cytotoxic cross matches should be obtained regardless of the PRA results
  • DONOR: Patient and donor pairs homozygous at a mismatched allele are considered a two-allele mismatch, i.e., the patient is A*0101 and the donor is A*0102, and this type of mismatch is not allowed

About this study

Official title: A Phase II Study of Optimally Dosed Clofarabine in Combination With Low-Dose TBI to Decrease Relapse Rates After Related or Unrelated Donor Hematopoietic Cell Transplantation in Patients With AML

This phase II trial studies the side effects and how well clofarabine works when given together with low-dose total-body irradiation (TBI) in treating patients with acute myeloid leukemia (AML) undergoing donor peripheral blood stem cell transplant (PBSCT). Giving chemotherapy and TBI before a donor PBSCT helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem 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.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To determine the maximum tolerated dose of clofarabine in combination with 2, 3, or 4 Gy TBI in preparation for hematopoietic cell transplantation (HCT) from human leukocyte antigen (HLA)-identical related and HLA-matched unrelated donors in patients with AML. (Part 1)

II. To determine the efficacy of the maximum tolerated dose of clofarabine combined with 2, 3, or 4 Gy TBI in reducing the 6 month relapse rate in patients with AML compared to our historical experience with fludarabine and 2 Gy TBI. A satisfactory improvement will be considered 6 month relapse rate declines from 35% to 20% among high-risk (objective for low risk group terminated August 2014). (Part 2)

SECONDARY OBJECTIVES:

  1. Leukemia-free and overall survivals.

II. Non-relapse mortality (NRM) of < 5% at 100 days.

III. Engraftment rate of >= 95%.

IV. Prognostic significance of cytogenetics and genetic markers not detected by traditional karyotype analysis, with special respect to tyrosine kinase receptor mutations (such as fms-like tyrosine kinase 3 [FLT3]), retrovirus-associated deoxyribonucleic acid (DNA) sequences (RAS)- and nucleophosmin gene mutations along with CCAAT/enhancer binding protein, alpha (C/EBP) mutations.

  1. Rigorous monitoring for minimal residual/recurring disease by standard morphologic, flow cytometric, and molecular techniques in order to facilitate early intervention.

VI. To evaluate the pharmacokinetics of clofarabine (pharmacokinetic samples discontinued January 2017).

OUTLINE: This is a dose-escalation study of clofarabine.

CONDITIONING REGIMEN: Patients receive clofarabine intravenously (IV) over 2 hours on days -6 to -2. Patients also undergo TBI on day 0.

IMMUNOSUPPRESSION: Patients with related donors receive cyclosporine orally (PO) every 12 hours on days -3 to 56 with taper to day 180 and mycophenolate mofetil PO every 12 hours on days 0 to 28. Patients with unrelated donors receive cyclosporine PO every 12 hours on days -3 to 100 with taper to day 180 and mycophenolate mofetil PO every 8 hours on days 0 to 40 with taper to day 96.

TRANSPLANTATION: Patients undergo allogeneic PBSCT on day 0.

What is being measured

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

  1. Part 1: Number of Participants With Dose Limiting Toxicities (DLT)

    The primary objective of part 1 is to determined the highest dose of clofarabine that can be tolerated safely in conjunction with nonmyeloablative transplant. If three patients successfully transplant without DLT, dose escalation occurs. If one of those three patients experiences DLT an additional three patients will be treated using the same dose. If a second DLT is observed in the first 3-6 patients, or if three patients are successfully transplanted without DLT at the highest dose the study will proceed to Part 2 using the maximum tolerated dose.

    A Clofarabine related dose-limiting toxicity is defined as a grade 4 toxicity involving the lungs, heart, liver (not resolving in 48 hours), kidneys (not resolving in 48 hours), gastrointestinal tract, and/or central nervous system.

    Measured: 14 days post-transplant

  2. Part 2: Number of Participants With Relapsed Disease

    Number of high risk patients with relapsed disease after receiving the maximum dose of clofarabine. Relapse is defined as the presence of >5% aberrant blasts by morphology on a marrow aspirate or the presence of circulating blasts in the peripheral blood.

    Measured: 6 months post-transplant

Secondary outcomes (7)
  1. Number of Participants Surviving Progression-free.

    Number of patients surviving without progressive disease post-transplant. Progression is defined as the presence of >5% aberrant blasts by morphology on a marrow aspirate or the presence of circulating blasts in the peripheral blood.

    Measured: 1 Year post-transplant

  2. Number of Participants Surviving Overall

    Number of patients surviving overall post-transplant.

    Measured: 1 Year post-transplant

  3. Number of Non-Relapse Mortalities (NRM)

    Number of patients who expired without disease progression/relapse.

    Measured: 100 days post-transplant

  4. Number of Participants Who Graft Rejected.

    Number of patients who graft rejected post-transplant. Graft rejection is defined as <5% donor peripheral blood T cells (CD3+).

    Measured: 1 Year post-transplant.

  5. Prognostic Significance of Cytogenetic and Genetic Markers

    Potential prognostic markers will be assessed by polymerase chain reaction (PCR) to determine their prognostic value.

    Measured: 1 Year post-transplant

  6. Number of Participants With Minimal Residual/Recurring Disease (MRD) Post-transplant

    Number of patients with MRD post-transplant, detected in the bone marrow as cytogenetic abnormalities or <5% monoclonal blasts by flow cytometry.

    Measured: 1 Year post-transplant

  7. Pharmacokinetics (PK) of Clofarabine

    Pharmacokinetic measurement of the volume of plasma from which clofarabine is completely removed per unit time. Clearance normalized to actual body weight. Pharmacokinetic analyses were performed on only a subset of patients and no aggregate calculations were made using the data.

    Measured: Blood was drawn on day -6 before the first clofarabine dosing, at the end of the infusion, and at 3, 4, 5, 6 and 24 hours after the start of infusion. Only pre-dose samples were drawn on days -5, -4, and -3.
