Dasatinib or Nilotinib Followed by Imatinib in Patients With Newly Diagnosed, Chronic Phase Chronic Myeloid Leukemia
First-Line Dasatinib or Nilotinib Followed by Response Guided Switch to Imatinib in Newly Diagnosed Chronic Phase Chronic Myeloid Leukemia
研究概览
详细说明
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.

描述
Inclusion Criteria:
- Newly diagnosed, previously untreated chronic phase chronic myeloid leukemia (CP-CML) (by World Health Organization [WHO] definition) (hydroxyurea permitted up to 7 days prior to enrollment)
- Clinically significant gastrointestinal disease, digestive dysfunction, or surgery that would compromise absorption of oral administration of medications
- Able to give written informed consent and comply with all study visits and procedures
Exclusion Criteria:
- Chronic myeloid leukemia (CML) in AP or BP

- Refuse or unable to perform telephone or video conferences with research coordinator
- Subjects who are pregnant, breast feeding or sexually active and unwilling to use effective birth control while on treatment with TKI
- Any medical or psychological condition that, in the opinion of the investigator, might interfere with the subject's participation in the trial, poses any additional risk for the subject, or confounds the assessment of the subject

The Proportion of Subjects Who Achieve Major Molecular Response (MMR)
大体时间:At 12 months
|
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

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

Change in Patient Reported Outcomes (PRO) Score Extracted From the MD Anderson Symptom Inventory-Chronic Myelogenous Leukemia (CML)
大体时间:Baseline to up to 12 months
