Primary Outcome Measures:
  • Hematologic response to include rate of response, actual values, change from baseline, and maximum change in hematologic parameters. [ Time Frame: 28 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and tolerability measures will include assessments of adverse events, vital signs, ECGs, physical exam findings, and laboratory assays (hematology, chemistry, and coagulation tests). [ Time Frame: 28 days of therapy, 2 week follow-up ] [ Designated as safety issue: Yes ]
  • Pharmacokinetic assessment will involve pre-dose plasma concentration of AKB-6548. [ Time Frame: 28 days ] [ Designated as safety issue: Yes ]
