        Inclusion Criteria:

          1. Patients 18 years of age or older with advanced CML (CML-AP, CML-BP and Philadelphia
             chromosome-positive acute leukemia) or refractory chronic phase CML are eligible, as
             defined as follows: The phase I portion of the study will be conducted first in
             advanced phase (accelerated phase CML, blast phase CML or Philadelphia-positive acute
             leukemia) patients. Once MTD is identified, a cohort of 6 patients with CML chronic
             phase who have failed prior therapy with at least two tyrosine kinase inhibitor will
             be treated at the MTD to determine if this dose is also acceptable for chronic phase
             patients. The phase II will be conducted in two treatment arms as follows: Treatment
             Arm A (Advanced phase disease) and treatment Arm B (Therapy for CP-CML
             refractory/resistant/suboptimally responding to at least two prior TKI's)

             following: a. 15-29% blasts in peripheral blood (PB) or bone marrow (BM), b.>20%
             basophils in PB or BM, c.>30% blasts plus promyelocytes (with blasts <30%) in PB or
             BM, d.<100 x109/L platelets unrelated to therapy, or Clonal cytogenetics evolution
             (i.e., the presence of cytogenetic abnormalities other than the Philadelphia
             chromosome) except if only present at the time of diagnosis and not associated with
             other features of accelerated phase. CML-BP is defined by the presence of >/=30%
             blasts in the bone marrow and/or peripheral blood or the presence of extramedullary
             disease, with myeloid or lymphoid blast morphology. Philadelphia-chromosome acute
             leukemias are eligible and defined by >/=20% blasts in the peripheral blood or bone
             marrow at the time of diagnosis.

             response to at least two tyrosine kinase inhibitors, or have intolerance to two prior
             tyrosine kinase inhibitors. For patient with prior intolerance, they should have
             received at least 2 TKI and experienced intolerance to one TKI and
             resistance/suboptimal

             months 2. Failure to achieve CCyR after >/= 6 months of therapy

          5. Patients with cytogenetic BCR-Abl variants and additional chromosomal abnormalities
             ('clonal evolution') will be eligible. Cytogenetics to be performed, but results are
             not required to start therapy in patients with hematologic progression

          6. Patients who have failed nilotinib, including those who are refractory to nilotinib at
             any dose or have relapsed on nilotinib at any dose will be eligible for the study.
             Patients currently on nilotinib will continue on their prescribed dose of nilotinib
             and MEK-162 will be added based on the current cohort level in phase I or at the
             established MTD in phase II. In the instance the nilotinib dose is greater than the
             current cohort (in phase 1) or the MTD (in phase 2) patients will be dose reduced to
             the dosage as prescribed by protocol and then dose escalated as allowed in protocol at
             the PIs discretion.

          7. For the phase I portion of the study, patients who had received prior therapy with
             nilotinib should have been able to tolerate the dose equivalent to the starting dose
             of nilotinib in the dose level at which the patient is being entered. Patients who
             previously received nilotinib but never at the dose being proposed are eligible
             provided they tolerated the maximum dose they were prescribed with no grade 3 or 4
             toxicity not responding to optimal management.

             study therapy and recovered from the toxic effects of that therapy. Exceptions to
             these are hydroxyurea and TKIs (including but not limited to imatinib, nilotinib,
             dasatinib, ponatinib and bosutinib), which should be discontinued ≥48 hrs prior to the
             start of therapy. Patients who are receiving nilotinib prior to enrollment do not have
