Primary Outcome Measures :
  1. The primary objective of this study is to evaluate the safety of MS-553 in patients with CLL/SLL whose disease relapsed after or was refractory to at least one prior therapy. [ Time Frame: Assessments for DLT and TEAE will occur during cycle 1. The primary endpoint will be the rate of DLT and TEAE requiring study drug discontinuation in the first 28 days ]
    The primary endpoint of this study is the incidence rate of dose-limiting toxicities and treatment-emergent adverse events requiring study drug discontinuation


Secondary Outcome Measures :
  1. To evaluate the clinical activity (i.e. the overall response rate (ORR) of MS-553 in patients with CLL/SLL whose disease relapsed after or was refractory to at least one prior therapy. [ Time Frame: Screening, post cycle 3 and 6 cycles (each cycle is 28 days) ]
    This will be assessed according to the International Workshop on Chronic Lymphocytic Leukemia Response Criteria with modifications for treatment-related lymphocytosis.


Other Outcome Measures:
  1. Pharmacokinetic (PK) parameters of MS-553 [ Time Frame: Time Frame: Cycle 1 day1, Cycle 1 Day 8, Cycle 2 Day 1(each cycle is 28 days) ]
    Evaluate Cmax

  2. Pharmacokinetic (PK) parameters of MS-553 [ Time Frame: Cycle 1 day 1, Cycle 1 Day 8 (each cycle is 28 days) ]
    Evaluate Tmax

  3. Pharmacokinetic (PK) parameters of MS-553 [ Time Frame: Cycle 1 Day 1, Cyle 1 Day 8 (each cycle is 28 days) ]
    Evaluate t1/2

  4. Pharmacokinetic (PK) parameters of MS-553 [ Time Frame: Cycle 1 day1, Cycle 1 Day 8, (each cycle is 28 days) ]
    Evaluate AUC (0-24; 0-∞)

  5. Evaluate pharmacodynamics biomarker,ability of MS-553 to inhibit PKC signaling (phosphorylation of PKC Beta substrate in patients with CLL/SLL treated with MS-553 [ Time Frame: C1D1 Pre-dose and C1D8 pre dose and 3 hours post dose ]
  6. Evaluate pharmacogenomic biomarkers in patients with CLL/SLL treated with MS-553 to compare germline DNA with tumor DNA via changes in sequence analysis [ Time Frame: C1D1 and the 1st day of each cycle and end of treatment (each cycle is 28 days) ]

Criteria

Inclusion Criteria:

To be eligible for inclusion in the primary escalation and expansion cohort 1 in this study, patients must meet all of the following criteria:

  1. Age 18 years or older
  2. Diagnosis of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL):

    1. History of histologically documented CLL or SLL that meets IWCLL diagnostic criteria according to the 2008 guidelines, and
    2. Indication for treatment as defined by the 2008 IWCLL guidelines, or the need for disease reduction prior to allogeneic transplantation

Exclusion Criteria:

Patients who meet any of the following criteria are not eligible for the primary escalation and expansion cohorts of this study:

  1. Current or past transformation of CLL/SLL to prolymphocytic leukemia (PLL), non-Hodgkin lymphoma, or Hodgkin lymphoma aggressive lymphoma outlined in the inclusion criteria for the optional cohort.
  2. Active and uncontrolled autoimmune cytopenia(s)
  3. Any of the following prior therapies within 14 days prior to cycle 1, day 1:

    1. Major surgery
    2. Corticosteroids greater than 20 mg / day prednisone (or equivalent), unless used by inhalation or topical route, or unless necessary for premedication before iodinated contrast dye, or for autoimmune hemolytic anemia
    3. Cytotoxic chemotherapy or biologic therapy, excepting BCR pathway kinase inhibitors for which no wash out is required (but must be stopped before cycle 1 day 1)
