Study Assessing Deep Molecular Response in Adult Patients With CML in Chronic Phase Treated With Nilotinib Firstline. (NILOdeepR)

Percentage of participants who were in deep molecular response MR4.5 (IS) at 24 months measured in a standardized EUTOS (European Treatment and Outcome Study for CML) MR4.5 laboratory. MR4.5 was defined as either (i) detectable disease ≤ 0.0032% BCR-ABL (fusion gene from breakpoint cluster region and Abelson genes) (IS) or (ii) undetectable disease in cDNA with 32000-99999 ABL1 transcripts or 77000-239999 glucuronidase beta (GUSB) transcripts.

Responders: Participants with a MR4.5 at 24 months, or if the assessment at this time point was missing, with a MR4.5 at 21 months Non-responders: Participants dropping out early or not providing sufficient data for any other reason. Participants who achieved MR4.5 before 24 months, but was no longer in MR4.5 at 24 months or progressed (or was no longer in MR4.5 at 21 months if evaluation at 24 months was missing).

Confidence intervals were calculated based on the Exact Clopper-Pearson method.

Percentage of participants with MR4 at 24 months of study treatment. MR4 (IS) is defined as either (i) detectable disease ≤0.01% BCR-ABL by IS or (ii) undetectable disease in cDNA with 10000 - 31999 ABL1 transcripts or 24000 - 76999 GUSB transcripts.

Confidence intervals were calculated based on the Exact Clopper-Pearson method.

Percentage of participants with MMR at 12 months of study treatment. MMR is defined as ≤ 0.1% BCR-ABL by IS, or equivalent to ≥ 3 log reduction of BCR-ABL transcript from standardized baseline.

Confidence intervals were calculated based on the Exact Clopper-Pearson method.

Percentage of participants with CCyR at 6 months of study treatment. Cytogenetic response was assessed as the percentage of Philadelphia positive (Ph+) metaphases in the bone marrow (a review of a minimum of 20 metaphases was required). CCyR was defined as a value of 0% Ph+ metaphases in bone marrow.

Confidence intervals were calculated based on the Exact Clopper-Pearson method.

Progression-free survival is defined as the time from the date of start of study treatment to the date of the first documented disease progression to accelerated phase (AP)/ blast crisis (BC) or death from any cause, whichever is earlier.

AP is defined as:

• 15% blasts in the peripheral blood or one marrow aspirate, but <30% blasts in both the peripheral blood and bone marrow aspirate
• 30% blasts plus promyelocytes in peripheral blood or bone marrow aspirate
• 20% basophils in the peripheral blood or bone marrow Thrombocytopenia (<100 x 109/Liter) that is unrelated to therapy Evidence of clonal evolution

BC is defined as:

≥ 30% blasts in peripheral blood or bone marrow aspirate Appearance of extramedullary involvement other than hepatosplenomegaly proven by biopsy (i.e., chloroma)

Time to progression to AP/BC is defined as the time from the date of start of study treatment to the date of earliest transformation to AP/BC, or CML-related death.

AP is defined as:

• 15% blasts in the peripheral blood or one marrow aspirate, but <30% blasts in both the peripheral blood and bone marrow aspirate
• 30% blasts plus promyelocytes in peripheral blood or bone marrow aspirate
• 20% basophils in the peripheral blood or bone marrow Thrombocytopenia (<100 x 109/L) that is unrelated to therapy Evidence of clonal evolution (with consensus of SC only)

BC is defined as:

≥ 30% blasts in peripheral blood or bone marrow aspirate Appearance of extramedullary involvement other than hepatosplenomegaly proven by biopsy (i.e., chloroma)

The EORTC QLQ-C30 is a patient completed 30 item questionnaire that is composed of both multi-item scales and single-item measures. These include five functional scales, three symptom scales, six single items and a GHS/QoL scale.

The GHS/QoL scale has 7 possible scores of responses (1=very poor to 7=excellent). Scores were averaged and transformed to 0 to 100. Higher scores indicate better quality of life.

A positive change from Baseline indicates improvement.

The physical functioning scale had 4 possible scores (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores were averaged and transformed to 0 to 100. Higher scores indicate better functioning. A positive change from baseline indicates improvement in physical functioning.

The role functioning scale had 4 possible scores (1=not at all, 2=a little, 3=quite a bit, 4=very much). Scores were averaged and transformed to 0 to 100. Higher scores indicate better functioning. A positive change from baseline indicates improvement in role functioning.

The EORTC QLQ-CML 24 is an internationally developed disease specific health-related quality of life questionnaire for CML patients. The questionnaire is composed of four multi-item scales and two single-item scales. The module consists of 24 items assessing symptoms burden (13 items), impact on worry/mood (4 items), impact on daily life (3 items), satisfaction with care and information (2 items) body image problems (1 item) and satisfaction with social life (1 item). The items were measured on four levels: 1=not at all, 2=a little, 3=quite a bit, 4=very much. For each domain, scores were averaged and transformed to 0 to 100. A higher score in symptom burden domain indicates a worse outcome. A negative change from baseline indicates improvement.
