Резюме

This randomized phase III trial studies clofarabine to see how well it works compared with daunorubicin hydrochloride and cytarabine when followed by decitabine or observation in treating older patients with newly diagnosed acute myeloid leukemia. Drugs used in chemotherapy, such as clofarabine, daunorubicin hydrochloride, cytarabine, and decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells. It is not yet known which chemotherapy regimen is more effective in treating acute myeloid leukemia.

Описание

PRIMARY OBJECTIVES:

I. To evaluate the effect of clofarabine induction and consolidation therapy on overall survival in comparison with standard therapy (daunorubicin [daunorubicin hydrochloride] & cytarabine) in newly-diagnosed acute myeloid leukemia (AML) patients age >= 60 years.

SECONDARY OBJECTIVES:

I. To evaluate complete remission (CR) rates, duration of remission, and toxicity/treatment-related mortality of clofarabine in comparison with standard therapy (daunorubicin & cytarabine) in newly-diagnosed AML patients age >= 60 years.

II. To evaluate the feasibility of consolidation with reduced-intensity conditioning and allogeneic hematopoietic stem cell transplantation from human leukocyte antigen (HLA)-identical donors in patients who achieve a response to induction therapy, including the incidence of successful engraftment, acute and chronic graft-versus-host disease, transplant-related mortality, and its impact on overall survival in comparison to patients receiving chemotherapy.

III. To evaluate the duration of remission and disease-free survival of patients in complete remission following completion of consolidation therapy who are subsequently randomized to receive scheduled low-dose decitabine maintenance in comparison with observation.

IV. To perform expression and methylation profiling on all patients receiving decitabine and to correlate their integrated epigenetic signatures with response to decitabine.

V. To examine the epigenetic profiles of remission marrow in patients randomized to observation vs. decitabine to determine whether epigenetic signature of apparently morphologically normal bone marrow is predictive of relapse or response to decitabine maintenance.

VI. To explore the possible association of response to clofarabine with ABC-transporter P-glycoprotein (Pgp).

VII. To assess the intensity of expression of CXC chemokine receptor type 4 (CXCR4) on diagnostic leukemia cells and to correlate this parameter with other established prognostic factors.

VIII. To assess the entire spectrum of somatic mutations and affected pathways at diagnosis of AML and elucidate the association between gene mutation and outcome.

IX. To examine the impact of smoking, obesity, regular acetaminophen use, regular aspirin use, benzene exposure, living in a rural/farm environment and some other underlying exposures and lifestyle factors associated with AML development on overall survival (OS).

X. To investigate potential correlative results between array comparative genomic hybridization (CGH) findings and acute myeloid leukemia patient characteristics.

TERTIARY OBJECTIVES:

I. To compare health-related quality of life (QOL) (physical, functional, leukemia-specific well-being) and fatigue in elderly AML patients receiving standard induction therapy with those receiving clofarabine.

II. To measure the change in health-related QOL that occurs over time (within treatment groups).

III. To comprehensively assess patient function at the time of study enrollment.

IV. To determine if components of a comprehensive geriatric assessment or QOL scales predict ability to complete AML treatment.

V. To describe the impact of transplant on QOL in AML patients above age 60.

OUTLINE:

INDUCTION THERAPY: Patients are randomized to 1 of 2 treatment arms.

ARM I (STANDARD THERAPY): Patients receive daunorubicin hydrochloride intravenously (IV) over 10-15 minutes on days 1-3 and cytarabine IV continuously on days 1-7. Patients with residual disease or those who do not achieve an aplastic bone marrow on day 12-14 (i.e., < 5% blasts and < 20% cellularity or markedly/moderately hypocellular) may receive a second course of induction therapy beginning no sooner than day 14.

ARM II: Patients receive clofarabine IV over 1 hour on days 1-5. Patients with residual disease or those who do not achieve an aplastic bone marrow on day 12-14 (i.e., < 5% blasts and < 20% cellularity or markedly/moderately hypocellular) may receive a second course of induction therapy beginning no sooner than day 21 and no later than day 56.

Patients who achieve a complete remission (CR) or CR with incomplete marrow recovery (CRi) after induction therapy proceed to consolidation therapy. Patients who are 60-69 years of age who achieve a "morphologic leukemia-free state" after induction therapy and who have an HLA-identical donor proceed to allogeneic stem cell transplantation.

CONSOLIDATION THERAPY: Beginning within 60 days after documentation of CR or CRi, patients receive consolidation therapy in the same arm they were randomized to for induction therapy.

ARM I (STANDARD THERAPY): Patients receive cytarabine IV over 1 hour once or twice daily on days 1-6. Treatment repeats every 4-6 weeks for 2 courses.

ARM II: Patients receive clofarabine IV over 1 hour on days 1-5. Treatment repeats every 4-6 weeks for 2 courses.

Patients who remain in CR after completion of consolidation therapy proceed to maintenance therapy.

MAINTENANCE THERAPY: Beginning within 60 days after completion of consolidation therapy, patients receive maintenance therapy and are randomized to 1 of 2 arms. Patients not eligible for randomization to decitabine maintenance after recovery from consolidation will be followed according to Arm I.

ARM I: Patients undergo observation monthly for 12 months.

ARM II: Patients receive decitabine IV over 1 hour on days 1-3. Treatment repeats every 4 weeks for 12 months the absence of unacceptable toxicity.

ALLOGENEIC STEM CELL TRANSPLANTATION WITH REDUCED-INTENSITY CONDITIONING REGIMEN: Patients begin reduced-intensity conditioning 30-90 days after the initiation of induction therapy.

CONDITIONING REGIMEN: Patients receive fludarabine phosphate IV over 30 minutes on days -7 to -3, busulfan IV over 2 hours every 6 hours on days -4 and -3 (for a total of 8 doses), and anti-thymocyte globulin IV over 4-6 hours on days -4 to -2.

TRANSPLANTATION: Patients undergo allogeneic peripheral blood stem cell transplantation on day 0.

After completion of study treatment, patients are followed up every 3 months for 4 years, every 6 months for 1 year, and then annually thereafter.

Резултат

Първични изходни мерки

1. Overall survival [Time between randomization and death from any cause, assessed up to 5 years]

Due to the potential confounding by maintenance therapy on the induction comparison, a weighted analysis (weighted Cox regression) will be used for the primary analysis.

Вторични изходни мерки

1. Mortality rate [30 days]

2. Induction complete response rates [Up to 5 years]

The induction response (CR + CRi) rates will be compared between the clofarabine arm and the standard treatment arm. At the end of the study, the 95% confidence interval on the difference in the CR + CRi rates (CR + CRi rate of standard treatment - CR + CRi rate of clofarabine) will be computed based on the normal approximation to the difference of two independent binomial proportions.

3. Disease-free survival (DFS) [Time from the second randomization to relapse or death without relapse, assessed up to 5 years]

The primary analysis of DFS will use a one-sided log rank test stratified on the induction therapy and on patient age and cytogenetics to determine the effect of decitabine on DFS as a maintenance therapy in comparison with observation.

4. Overall survival [Up to 5 years]

To evaluate the impact of consolidation with non-ablative conditioning and allogeneic hematopoietic stem cell transplantation with an HLA-identical sibling on overall survival in patients who achieve a 'morphologic leukemia-free state, a one-sided log rank test stratified on age, therapy-related AML, the presence of AHD at the time of diagnosis of AML, and the induction therapy they received will be used.

5. Epidemiological factors, measured using the Acute Leukemia Epidemiology and Survival in ECOG (ALESE) questionnaire [Baseline]

The proportions of obese patients and patients who had benzene exposure, ever smoked in their lifetime, took aspirin regularly, took acetaminophen regularly, ever lived in rural/farm environments, or had other exposures or lifestyle factors will be calculated separately, along with their 95% confidence intervals.

6. Change in the Functional Assessment of Cancer Therapy (FACT)-Leukemia-specific (Leu) Trial Outcome Index (TOI) score [Baseline to 30 days after beginning induction therapy]

Descriptive statistics will be provided and Cronbach's alpha will be calculated at each time point to assess reliability. Repeated measures analysis techniques will also be utilized to examine the treatment effect and time effect on FACT-Leu TOI score. For patients randomized to the induction treatments, the longitudinal scores collected from time of randomization, two weeks after beginning induction therapy (at the time of nadir), and at 28-30 days after beginning induction therapy, will be analyzed according to the methods described in Schluchter and Schluchter, Greene and Beck.

7. Change in the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue score [Baseline to 30 days after beginning induction therapy]

Descriptive statistics will be provided and Cronbach's alpha will be calculated at each time point to assess reliability. Repeated measures analysis techniques will also be utilized to examine the treatment effect and time effect on FACIT Fatigue score. For patients randomized to the induction treatments, the longitudinal scores collected from time of randomization, two weeks after beginning induction therapy (at the time of nadir), and at 28-30 days after beginning induction therapy, will be analyzed according to the methods described in Schluchter and Schluchter, Greene and Beck.

Други изходни мерки

1. Epigenetic signatures, determined by expression and methylation profiling [Up to 5 years]

The methods described in Thompson et.al will be used to identify epigenetics signatures which are different between patients who relapsed and patients who did not relapse. Signatures identified by epigenetic analysis will be correlated with DFS using a least angle regression and shrinkage (LARS)/least absolute shrinkage and selection operator (LASSO) approach for each maintenance arm.

2. Gene expression levels [Up to 5 years]

Genes will be filtered by examining ratios of standard deviation to the mean. Genes will be hierarchically clustered to find genes with high/low fold change/differences. Supervised analyses will be used to identify genes that are differentially expressed between patients who relapsed and patients who did not relapsed. Genes or epigenetic signatures identified by gene expression or epigenetic analysis will be correlated with DFS using LARS/LASSO approach.

3. Predictive mutations [Up to 5 years]

For each mutation a stratified log-rank test will be performed (using the strata at randomization) adjusted for multiple testing using resampling and the min-p method of Westfall and Young as implemented in the R package multtest. In addition tests for interaction between treatment assignment and mutational status will be performed to identify potential predictive mutations. The prognostic relevance of known mutations on overall survival and response to therapy will be assessed, and novel mutations identified in discovery studies and by other efforts will also be included.

4. Prognostic risk groups [Up to 5 years]

Prognostic risk groups will be identified by using recursive partitioning and logistic regression, both of which are highly suitable for binary predictors. A randomly chosen subsample of 423 (2/3 of 635) patients will be used for training these models and the remaining 212 for validation.

5. Pgp levels [Up to 5 years]

The possible association of response to clofarabine with Pgp will be explored using a Wilcoxon rank-sum test.

6. CXCR4 expression levels [Up to 5 years]

Expression intensity of CXCR4 will be divided into three groups (low, intermediate, high). The grading will be further simplified as high/intermediate vs. low. Data will be first analyzed by induction treatment arms. When data are available, logistic and Cox regression analysis, adjusted by treatment effect and prognostic factors (including cytogenetics), will be used to assess whether CXCR4 expression level is an independent predictor for response or survival.
