Bortezomib and Sorafenib Tosylate in Treating Patients With Newly Diagnosed Acute Myeloid Leukemia

This randomized phase III trial studies how well bortezomib and sorafenib tosylate work in treating patients with newly diagnosed acute myeloid leukemia. Bortezomib and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving bortezomib and sorafenib tosylate together with combination chemotherapy may be an effective treatment for acute myeloid leukemia.

PRIMARY OBJECTIVES: I. To compare event-free survival (EFS) and overall survival (OS) in 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 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. SECONDARY 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 stem cell transplant (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 methylcytosin Покажи пълното описание...
