    PRIMARY OBJECTIVES: I. To compare event-free survival (EFS) and overall survival (OS) of patients with de novo acute myeloid leukemia (AML) without high allelic ratio fms-like tyrosine kinase (FLT3)/internal tandem duplications (ITD)+ mutations who are randomized to standard therapy versus bortezomib/standard combination therapy. II. To determine the feasibility of combining bortezomib with standard chemotherapy in patients with de novo AML. III. To compare the OS and EFS of high-risk patients treated with intensive Induction II with historical controls from AAML03P1 and COG-AAML0531. IV. To determine the feasibility of administering sorafenib (sorafenib tosylate) with standard chemotherapy and in a one year maintenance phase in patients with de novo high allelic ratio FLT3/ITD+ AML. SECONDRY OBJECTIVES: I. To assess the anti-leukemic activity of sorafenib in patients with de novo high allelic ratio FLT3/ITD+ AML. II. To compare the percentage of patients converting from positive minimal residual disease (MRD) to negative MRD after Intensive Induction II with historical controls from AAML03P1 and AAML0531. III. To compare OS, disease-free survival (DFS), cumulative incidence of relapse, and treatment-related mortality from end of Intensification I between patients allocated to best allogenic donor stem cell transplant (SCT) and comparable patients on AAML0531 who did not receive allogenic donor SCT. IV. To compare OS, DFS, cumulative incidence of relapse, treatment-related mortality, and severe toxicity between patients allocated to matched family donor SCT on AAML1031 and AAML0531. V. To assess the health-related quality of life (HRQOL) of patients treated with chemotherapy and SCT for AML. VI. To evaluate bortezomib pharmacokinetics (PK) in patients receiving the combination regimen. VII. To obtain sorafenib and metabolite steady state pharmacokinetics and pharmacokinetic-pharmacodynamic data in subjects with FLT3/ITD receiving sorafenib. VIII. To compare the changes in shortening fraction/ejection fraction over time between patients treated with and without dexrazoxane. IX. To refine the use of minimal-residual disease (MRD) detection with 4-color flow cytometry. X. To evaluate the prognostic significance of molecular MRD and its contribution to risk identification with multidimensional flow cytometry (MDF)-based MRD in patients with translocations amenable to quantitative real time (RT)-polymerase chain reaction (PCR) (e.g., t(8;21), inv(16), t(9;11), Wilms tumor 1 [WT1] expression). XI. To determine the leukemic involvement of the hematopoietic early progenitor cell and its role in defining response to therapy. XII. To define the leukemic stem cell population in patients with AML. XIII. To determine the prevalence and prognostic significance of molecular abnormalities of WT1, runt-related transcription factor (RUNX)1, mixed-lineage leukemia (MLL)-partial tandem duplication (PTD), tet methylcytosine dioxygenase 2 (TET2), Cbl proto-oncogene, E3 ubiquitin protein ligase (c-CBL), v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT), and other novel AML-associated genes in pediatric AML. XIV. To correlate the expression of cluster of differentiation (CD74) antigen as well as proteasome beta 5-subunit (PSMB5) gene expression and mutation with response to bortezomib. XV. To evaluate the changes in protein expression and unfolded protein response (UPR) in patients with AML. XVI. To determine the expression level of wild-type FLT3, and correlate with outcome and in vitro sensitivity to FLT3 inhibition. XVII. To collect biology specimens at diagnosis, treatment time points, and relapse for future biology studies XVIII. To create a pediatric-specific algorithm to predict the occurrence of grade 2-4 acute graft-versus-host disease (GVHD) prior to its clinical manifestations using a combination of pre-transplant clinical variables and serum GVHD biomarker concentrations in the first weeks after SCT.

  2. A Multi-Center, Phase III, Randomized Trial of Reduced Intensity (RIC) Conditioning and Transplantation of Double Unrelated Umbilical Cord Blood (dUCB) Versus HLA-Haploidentical Related Bone Marrow (Haplo-BM) for Patients With Hematologic Malignancies (BMT CTN #1101)
    Phoenix/Scottsdale, Ariz. View Summary

    A Multi-Center, Phase III, Randomized Trial of Reduced Intensity (RIC) Conditioning and Transplantation of Double Unrelated Umbilical Cord Blood (dUCB) Versus HLA-Haploidentical Related Bone Marrow (Haplo-BM) for Patients With Hematologic Malignancies (BMT CTN #1101)

    Location:

    Trial status:

    Open for Enrollment

    Why is this study being done?

    Reduced intensity conditioning (RIC) blood or marrow transplantation (BMT) has allowed older and less clinically fit patients to receive potentially curative treatment with allogeneic HCT for high risk or advanced hematological malignancies. Patients lacking an HLA-matched sibling may receive a graft from a suitably HLA-matched unrelated donor. However, up to a third of patients will not have an HLA-matched sibling or a suitably matched adult unrelated donor (i.e., no more than a mismatch at a single locus). Even when a suitably matched unrelated donor is identified, data from the National Marrow Donor Program (NMDP) indicate that a median of four months is required to complete searches that result in transplantation; thus, some number of patients succumb to their disease while awaiting identification and evaluation of a suitably matched adult unrelated donor. Single or dual center studies have shown that partially HLA-mismatched related bone marrow (haplo-BM) and unrelated double umbilical cord blood (dUCB) are valuable sources of donor cells for RIC HCT, thus extending this treatment modality to patients who lack other donors. In order to study the reproducibility, and thus, the wider applicability of these two alternative donor strategies, The Blood and Marrow Transplantation Clinical Trials Network (BMT CTN) conducted two parallel multicenter prospective Phase II clinical trials. These two studies evaluated the safety and efficacy of related haplo-BM (BMT CTN 0603) and dUCB (BMT CTN 0604) transplantation after RIC. Both of these alternative donor approaches produced early results similar to that reported with unrelated donor, and even HLA-matched sibling, HCT. These data demonstrate not only the efficacy of both of these approaches, but also that both can be safely exported from the single center setting. Both haplo-BM and dUCB grafts can be obtained rapidly for greater than 90% of patients lacking an HLA-matched donor. This study will test the hypothesis that progression free survival at two years after RIC haplo-BM transplantation is similar to the progression free survival after RIC dUCB transplantation.
