• AST and ALT ≤ 2.5 x ULN or ≤ 5.0 x ULN if considered due to leukaemia
• Alkaline phosphatase ≤ 2.5 x ULN unless considered due to leukaemia
• Total bilirubin ≤ 1.5 x ULN, except know Mb Gilbert
• Serum lipase and amylase ≤ 1.5 x ULN
• Serum creatinine ≤ 1.5 x ULN

Exclusion Criteria:

• Pre-treatment with HU for > 3 months and with imatinib is not permitted

• Concurrent uncontrolled medical conditions (e.g. uncontrolled diabetes, active or uncontrolled infections,acute or chronic liver and renal disease) that could cause unacceptable safety risks or compromise compliance with the protocol
• Impaired gastrointestinal function or disease that may alter the absorption of study drug (e.g.ulcerative disease,uncontrolled nausea,vomiting and diarrhea,malabsorption syndrome,small bowel resection or gastric by-pass surgery)
• Concomitant medications with potential QT prolongation (see link for complete list: http://www.torsades.org/medical-pros/drug-lists/printable-drug-list.cfm)
