Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Observe toxicity of drug combination See protocol Observe effect measured as response by molecular assesment of BCR-ABL transcript. fraction in So called major molecular rfemission (i.e 3 log below debut levels) ;Secondary Objective: Observe toxicity of drug combination See protocol Observe fraction of patients who achieve a very good response (So called major molecular remission, which is less than a thousandth of the disease burden at diagnosis;Primary end point(s): Primary endpoint: Safety endpoint in run-in phase (first 15 patients): Study stops if four out of the first five, six of the first 10 or 8 of the first 15patients experience grade IV hematological toxicity, grade III non-hematological toxicity or grade II serosal effusions during first 6 months of treatment. Data will be evaluated by an independent safety committee. Whole study efficacy endpoint: Rate of MMR after 12 months. ;Timepoint(s) of evaluation of this end point: 6 months for safety 12 months for efficacy | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary Endpoint (s) • Rate of CCgR after 3, 6, 12 and 18 months • Rate of MMR after 3, 6, 15, 18, and 24 months • Rate of MR4.0 and MR4.5 after 3, 6, 12, 15, 18, and 24 months • Rate of grade 2 non-hematological toxicity that poses a clinical problem (duration more than one month in spite of symptomatic treatment) • Rate of grade 3-4 hematological toxicity • Overall survival • Rate of patients who complete 3, 6 and 12 months of PegIFN treatment • QoL at 0, 3, 6, 12 and 18 months • Progression to advanced disease phase. • Comparison of safety and efficacy variables with historical cohorts from Nord CML006 and NordCML002 • Biomarkers of response, failure and toxicity. A) Fraction of leukemic cells in the stem cell (Ph+ CD34+CD38- cells) and progenitor cell (Ph+ CD34+CD38+) compartment at debut and 4 weeks of dasatinib treatment. B) Lymphocyte subpopulations at 0, 3 and 6 months by flow cytometry assay: Enumeration of CD4+ and CD8+ T-cells, NK-cells, NKT-cells, B-cells and regulatory T-cells. Correlation of these subpopulations to response. C) Functional assays of lymphocytes: Cytotoxicity of NK-cells. IFN-? production by T cells after stimulation. Granzyme B staining for evaluating the cytotoxic potential of T-cells. Functional assays will be performed both from pre- and post-drug samples. D) Clonality: TCR ?d rearrangements by PCR E) Plasma cytokine array: Luminex multiplex system F) Proteomics A simplified follow-up of treatment response by real-time quantitative reverse transcriptase PCR (RQ-PCR), treatment type, progression to advanced phase and survival will be performed yearly until end of year 5. ;Timepoint(s) of evaluation of this end point: See above | — |
