This is a phase II multi-center, randomized, double blind, placebo-controlled trial.

The investigators are doing this study to see if a new drug, abatacept, can be used together with a calcineurin inhibitor (cyclosporine or tacrolimus) and methotrexate to provide better protection against Acute Graft versus Host Disease (aGvHD) without causing more infections.

Primary Outcome Measures:
  • Cumulative incidence of severe aGVHD at day +100 post-transplant in the standard and investigational study arms [ Time Frame: First 100 days after transplant ] [ Designated as safety issue: Yes ]
    The primary analysis will consist of estimating the cumulative incidence of severe aGVHD at day +100 post-transplant in the standard and investigational study arms. All registered patients will be considered for this analysis. The primary null hypothesis of the study is that there will be no difference in severe aGVHD between the investigational and standard GVHD prophylaxis arms. The primary outcome will be assessed in a final analysis to be performed after the last enrolled patient has been followed for 100 days post-transplant. The cumulative incidence and confidence interval will be calculated. The cumulative incidence will be compared between treatment arms using logistic regression models. Relapse will be considered a competing risk for aGVHD to negate the effect of measures, such as withdrawal of immune suppression and donor-lymphocyte infusion, often used in response to relapse.

Secondary Outcome Measures:
  • A cumulative incidence of serious infection, engraftment, relapse, and overall survival will be computed. [ Time Frame: 5 years post transplant ] [ Designated as safety issue: Yes ]
    A cumulative incidence of infection, serious infection, CMV viremia, CMV invasive disease, EBV viremia, PTLD, BK viremia and disease, adenovirus viremia and disease, engraftment of: neutrophils, platelets, lymphocyte count, total T cell counts, CD4+ T cell counts, and CD8+ T cell counts, secondary graft failure, graft rejection, all grades of early and late aGvHD, overlap syndrome, chronic GvHD, RRT, TRM, DFS, immunosuppression-free survival, immunosuppressive-free/relapse-free survival, relapse, and OS.

  Show Detailed Description


Ages Eligible for Study:   6 Years and older   (Child, Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Must be at least 6 years old and weigh 20 kg.
  2. Must have a willing unrelated adult donor (bone marrow or peripheral blood). Donors may have a single mismatch (i.e. be a 7/8) and this mismatch may be at the allele or antigen level; however, donors with allele level disparity should be given preference over those with antigen level disparity. The use of mismatched donors in which disparity is only in the host versus graft direction (because of recipient homozygosity) is discouraged because of the potentially heightened risk for graft rejection. Centers may perform extended typing (e.g. DQB1 and DPB1) according to institutional practices and use these results in selecting donors; however, it is recommended that this extending typing be used only to select between donors who are equally well matched with the recipient at the A, B, C and DRB1.
  3. All patients and/or their parents or legal guardians must sign a written informed consent. Assent, when appropriate, will be obtained according to institutional guidelines.
  4. Must have a high risk hematologic malignancy as defined below:

    1. Acute myeloid leukemia (AML).
    2. Myelodysplastic syndrome

    (i) Adult patients (≥21 years) must meet criteria for intermediate, high or very high-risk disease based on the World Health Organization classification based prognostic scoring system.

Intermediate risk (2 points), high risk (3-4 points), very high risk (4-5 points)

  • RA = refractory anemia, RARS = refractory anemia with ringed sideroblasts, RCMD = refractory cytopenia with multilineage dysplasia, RCMD-RS = refractory cytopenia with multilineage dysplasia and ringed sideroblasts, RAEB-1 = refractory anemia with excess of blasts-1 (5-9% blasts), RAEB-2 = refractory anemia with excess of blasts-2 (10-19% blasts).
  • *Karyotype: Good = normal, -Y, del(5q), del(20q), Poor = complex (≥ 3 abnormalities), chromosome 7 anomalies, Intermediate = other abnormalities.

    • *RBC transfusion requirement = having ≥ 1 RBC transfusion every 8 weeks over a 4-month period.

(ii) Pediatric patients with MDS, regardless of subtype, will be eligible.

(c) Acute lymphoblastic leukemia (ALL). (i) Given the poor prognosis of adults (≥21 years) with ALL, adults in 1st or greater complete remission will be eligible.. CR is defined as an M1 marrow (<5% blasts), no evidence of extramedullary disease, and an absolute neutrophil count ≥ 1.0 x 109/L. Complete remissions without platelet recovery (CRp) will be considered remissions (ii) Given the generally good prognosis of children (<21 years) with ALL, they will have to meet one of the criteria listed below. Additionally, children who are enrolled on a COG ALL trial for newly diagnosed or relapsed disease will have to meet the criteria for BMT outlined in that trial. CR is defined as an M1 marrow (<5% blasts), no evidence of extramedullary disease, and an absolute neutrophil count ≥ 1.0 x 109/L. Complete remissions without platelet recovery (CRp) will be considered remissions.

  1. In 1st complete remission with a very high risk for relapse.

    1. Haplodiploidy (<44 chromosomes)
    2. >1% residual marrow blasts by flow cytometry at the end of induction.
    3. >0.01% residual marrow blasts by flow cytometry at the end of consolidation.
    4. Early T-Cell Precursor (ETP) phenotype
  2. In 2nd complete remission with B-lineage disease after a marrow relapse occurring less than 36 months from diagnosis.
  3. In 2nd complete remission with T-lineage disease or Ph+ disease after a marrow relapse occurring at any time.
  4. In a 2nd complete remission with T-lineage disease after an extra-medullary relapse occurring less than 18 months from diagnosis.
  5. In 3rd or greater complete remission after a marrow or extramedullary relapse

    (d) Patients with acute undifferentiated, biphenotypic, or bilineal leukemia, which is in 1st or greater complete remission (CR) or partial remission (PR). Cr will be defined as an M1 marrow (<5% blasts), no evidence of extramedullary disease, and an absolute neutrophil count ≥ 1.0 x 109/L. CR without platelet recovery (CRp) will be considered complete remissions.) PR will be defined as an M2 marrow (5-19% blasts), no evidence of extramedullary disease, and an absolute neutrophil count ≥ 1.0 x 109/L.).

    (e) Chronic myelogenous leukemia (CML). (i) Chronic phase with resistance to tyrosine kinase inhibitors. (ii) accelerated phase (development of cytogenetic abnormality in addition to t(9:22), blood blast percentage ≥10, blood basophil percentage ≥20, platelet count <100,000 X 109/L) (iii) blast crisis. (iv) 2nd or greater chronic phase.

    (f) Acute Lymphoblastic Lymphoma in 2nd or greater complete remission. Complete remission includes confirmed complete response (CR) defined as the disappearance of all evidence of disease from all sites for at least 4 weeks. Bone marrow and CSF must be normal and any macroscopic nodules in any organs detectable on imaging techniques should no longer be present. Imaging should include PET scanning. CR will also include unconfirmed complete responses defined as a residual lymph node mass > 1.5 cm in greatest transverse diameter that has regressed by > 75% in sum of the products of the greatest perpendicular diameters (SPD), or any residual lesions in organs that have decreased by > 75%, with a negative PET scan, negative bone marrow and CSF.

    (h) Chronic lymphocytic leukemia (CLL) (i) Newly diagnosed disease with 17p- (ii) Disease beyond first CR that has been treated with a fludarabine containing regimen.

    (i) Chronic myelomonocytic leukemia.

    (j) Atypical (BCR-ABL negative) chronic myelogenous leukemia

    (k) Hodgkin lymphoma that has recurred or progressed after an autologous BMT. Disease must be chemosensitive; salvage chemotherapy must produce at least a partial response.

    (l) Non-Hodgkin lymphomas that has recurred or progressed after an autologous BMT.
