Nilotinib Versus Standard Imatinib (400/600 mg Every Day (QD)) Comparing the Kinetics of Complete Molecular Response for Chronic Myelogenous Leukemia in Chronic Phase (CML-CP) Pts With Evidence of Persistent Leukemia by Real-time Quantitative Polymerase Chain Reaction (RQ-PCR)

4 oktober 2016 uppdaterad av: Novartis Pharmaceuticals

An Open Label, Randomized Study of Nilotinib vs. Standard Imatinib (400/600 mg QD) Comparing the Kinetics of Complete Molecular Response for CML-CP Patients With Evidence of Persistent Leukemia by RQ-PCR.

The primary goal of this study was to determine the rate of confirmed best cumulative complete molecular response (CMR) within the first year of study therapy with imatinib or nilotinib. The study also explored the impact and significance of the achieved CMR on patient outcomes (progression free survival (PFS), event free survival (EFS) and overall survival (OS), characterized the kinetics of CMR achieved in both treatment arms and after the cross-over.

Exclusion Criteria:

Patient has evidence of rising PCR (a confirmed >1 log increase in previous 6 months) Patient has received another investigational agent within last 6 months or tyrosine kinase inhibitors (TKIs) other than imatinib Prior allogeneic stem cell transplantation

Inability to monitor the QT interval on electrocardiogram (ECG) Long QT syndrome or a known family history of long QT syndrome. Clinically significant resting brachycardia (<50 beats per minute) QTc > 450 msec on baseline ECG (using the QTcF formula).

Åtgärdsbeskrivning
Tidsram
Rate of Confirmed Best Cumulative Complete Molecular Response (CMR)
Tidsram: 12 months
The rate of confirmed best cumulative CMR was defined as the number of participants who had confirmed CMR during the first 12 months of treatment after the randomization date. Participants who achieved confirmed best cumulative CMR during the first 12 months were considered responders. Participants who dropped out early or who did not provide sufficient data for any reason were considered to be non-responders. The definition of CMR is undetectable BCR-ABL (fusion gene formed between bcr gene from chromosome 22 and abl gene from chromosome 9) where BCR-ABL ratio in % international scale (IS) ≤ 0.00001 by real-time quantitative polymerase chain reaction (RQ-PCR) where there was no detectable BCR-ABL and 1) the test had a sensitivity of at least 4.5 logs below the standardized baseline; 2) RQ-PCR negativity was confirmed on the next RQ-PCR sample (usually 3 months later); and 3) the date of confirmed CMR was the date of the first of two negative results with sensitivity >4.5 logs.

PFS was defined as the time from the date of randomization to the date of the earliest documented progression-defining event as follows: transformation to blast crisis or accelerated phase disease, or death from any cause.

Event-free Survival
Tidsram: 48 months
Event-free survival was defined as the time from the date of randomization to the date of first occurrence of any of the following events on study treatment: loss of complete hematological response, confirmed loss of complete cytogenetic response (CCyR), confirmed loss of major molecular response (MMR), death from any cause during treatment, progression to the accelerated phase or blast crisis of chronic myelogenous leukemia (CML) per European Leukemia Network (ELN) criteria, whichever was earliest.
