NCT ID: NCT00124748

Last Updated: 2012-02-03

Results Overview

MMR is defined as Bcr-Abl (A fusion gene of the breakpoint cluster region \[Bcr\] gene and Abelson proto-oncogene \[Abl\] genes) transcript ratio ≤0.1% (≥ 3 log reduction of BCR-ABL transcripts from a standardized baseline), as detected by reverse transcriptase polymerase chain reaction \[RT-PCR\] (performed centrally).

SECONDARY outcome

Timeframe: From first complete cytogenetic response to first confirmed loss or censoring

Population: Intent-to-treat (ITT) population consisted of all patients who are randomized into the study.

Duration of CCyR was defined as the time between date of CCyR and the earliest of either (1) loss of CCyR OR (2) (Chronic Myeloid Leukemia) CML-related death or progression to (Accelerated Phase/Blast Crisis) AP/BC during study treatment. Estimated rate of duration of first CCyR was analyzed by Kaplan-Meier estimate (percent probability and 95% Confidence interval).

Imatinib 400 mg
n=157 Participants
Oral dose of 400mg Imatinib once daily (q.d.). All patients received the assigned dose starting on Day 0 (Visit 3). The dose of Imatinib could be interrupted, reduced, or escalated based on guidelines defined in protocol.
Imatinib 800 mg
n=319 Participants
Patients randomized to receive 800 mg Imatinib were to receive 400 mg twice daily (b.i.d.) oral administration, in the morning and the evening.

Timeframe: start of treatment to Month 36

Population: Safety analysis population (SAP): consisted of all patients who received at least one dose of study medication.Subjects are summarized according to the safety treatment allocation (the dose they actually received).

The mean actual dose intensity per day from start of treatment up to last dose or discontinuation was evaluated up to Month 36. Actual dose intensity (mg/day) = total dose/time on treatment (periods of zero dose are included)

Timeframe: 42 months

Population: Intent-to-treat (ITT) population consisted of all patients who were randomized to the study treatment. Patients without a valid polymerase chain reaction (PCR) assessment or those who had experienced an event before the landmark were excluded from analysis

A Landmark Kaplan-Meier analysis was performed for PFS at 42 months by MMR status at 6, 12, and 18 months to investigate their prognostic value.

SECONDARY outcome

Timeframe: 48 months overall

Population: This analysis was not done because no major molecular improvement was observed in the 800mg dose compared to 400mg dose. Hence, analysis for complete molecular response was not necessary.

Complete Molecular Response is defined as a Bcr-Abl (a fusion of gene of Bcr and ABl genes) ratio ≤0.0032% on the International Scale Bcr = breakpoint cluster gene Abl = abelson proto-oncogene.
