What was measured

This outcome measure was defined as the time from the date of reinitiation of nilotinib treatment following loss of major molecular response (MMR) to the date of first documented achievement of molecular response 4.5 (MR4.5). Participants who did not regain MR4.5 after reinitiation of treatment on or before the data cut-off date were censored at the date of their last available BCR-ABN PCR assessment. MR4.5 corresponds to a BCR-ABN transcript level ≤0.0032% on the International Scale (IS).

Analysis population: The nilotinib treatment re-initiation (NTRI) safety set included all participants who received at least one dose of study medication during the nilotinib treatment re-initiation phase.

Groups in this outcome

NTRI Phase

Participants who experienced loss of major molecular response during the treatment-free remission (TFR) phase entered the nilotinib treatment re-initiation (NTRI) phase. During this phase, nilotinib treatment was re-initiated at a dose of 300 mg twice daily.

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
