Clinical Trial Summary

This phase II trial studies how well dasatinib, nilotinib, and imatinib mesylate works in treating patients with newly diagnosed, previously untreated chronic myeloid leukemia in which fewer than 10% of the cells in the blood and bone marrow are blast cells (immature blood cells) (chronic phase). Dasatinib, nilotinib, and imatinib mesylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Description:

PRIMARY OBJECTIVE:

I. To assess incidence of major molecular response (MMR) at 12 months.

SECONDARY OBJECTIVES:

I. To assess progression free survival (PFS) at 12 and 24 months.

II. To assess accelerated phase (AP) or blast phase (BP) transformation-free survival at 12 and 24 months.

III. To assess incidence of deep MRs (≥ MR⁴) at 12 months and 24 months.

IV. To assess safety.

V. To assess patient reported outcomes (PRO).

TERTIARY OBJECTIVES:

I. To assess prognostic significance of detecting aberrant myeloid or lymphoid markers on diagnostic bone marrow.

II. To assess ability to enroll subjects who maintain deep molecular remissions in tyrosine kinase inhibitors (TKIs) discontinuation trials.

OUTLINE:

Patients receive dasatinib orally (PO) once a day (QD) or nilotinib PO twice a day (BID) at the discretion of the treating hematologist. Patients achieving either a 1 log reduction at 3 months or a 2 log reduction at 6 months in their breakpoint cluster region-abelson murine leukemia viral oncogene homolog 1 (BCR-ABL1) transcript levels may switch to imatinib mesylate PO QD.

After completion of study treatment, patients are followed up at 2 weeks and then up to 60 months.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	The Proportion of Subjects Who Achieve Major Molecular Response (MMR)	Response will be measured by a decrease in fusion transcript or protein resulting from the 9;22 chromosomal translocation responsible for formation of the Philadelphia Chromosome (BCR-ABL1) levels on a logarithmic scale. A 1 log reduction is a drop to below 10%, while a major molecular response (MMR) is defined as a 3 log reduction (0.1%).	At 12 months
Secondary	Accelerated Phase (AP) or Blast Phase (BP) Free Survival	Survival will be defined as the time from CML diagnosis to the time of transformation to accelerated phase (AP) or blast phase (BP).	The time of CML diagnosis to the time of transformation to AP or BP, assessed up to 24 months
Secondary	Change in Patient Reported Outcomes (PRO) Score Extracted From the MD Anderson Symptom Inventory-Chronic Myelogenous Leukemia (CML)	The patient reported outcomes (PRO) score extracted from the MD Anderson Symptom Inventory (MDASI)-Chronic Myelogenous Leukemia (CML) will be determined and intra and inter subject changes will be compared.	Baseline to up to 12 months
Secondary	Duration of Adverse Events (AEs) Using the Common Terminology Criteria for Adverse Events (CTCAE) v4.03 Criteria	Listings of laboratory test results will also be generated, and descriptive statistics summarizing the changes in laboratory tests over time will be presented. Exposure to drug over time will also be summarized. The AE incidence rates, as well as the frequency of occurrence of overall toxicity, categorized by toxicity grades (severity) will be described as obtained from subject forms and subject communications.	Up to 30 days after the end-of-treatment
Secondary	Frequency of Adverse Events (AEs) Using the Common Terminology Criteria for Adverse Events Version 4.03 (CTCAE v4.03) Criteria	Listings of laboratory test results will also be generated, and descriptive statistics summarizing the changes in laboratory tests over time will be presented. Exposure to drug over time will also be summarized. The AE incidence rates, as well as the frequency of occurrence of overall toxicity, categorized by toxicity grades (severity) will be described as obtained from subject forms and subject communications.	Up to 30 days after the end-of-treatment
Secondary	Progression Free Survival (PFS)	Progression free survival (PFS) will be defined as the time from CML diagnosis to the time of loss of major molecular response (MMR) or loss of hematologic response.	The time of CML diagnosis to the time of loss of MMR or loss of hematologic response, assessed up to 24 months
Secondary	Severity of Adverse Events (AEs) Using the Common Terminology Criteria for Adverse Events (CTCAE) v4.03 Criteria	Listings of laboratory test results will also be generated, and descriptive statistics summarizing the changes in laboratory tests over time will be presented. Exposure to drug over time will also be summarized. The AE incidence rates, as well as the frequency of occurrence of overall toxicity, categorized by toxicity grades (severity) will be described as obtained from subject forms and subject communications.	Up to 30 days after the end-of-treatment
Secondary	The Number of Subjects With Breakpoint Cluster Region-abelson Murine Leukemia Viral Oncogene Homolog 1 (BCR-ABL1) Transcript Levels = Deep Molecular Responses (MR4)	Descriptive statistics will summarize the changes in breakpoint cluster region-abelson murine leukemia viral oncogene homolog 1 (BCR-ABL1) testing over time will be presented.	Up to 24 months
