Brief summary
This study will assess the pharmacokinetics of nilotinib in Ph+ CML pediatric patients that are newly diagnosed or resistant or intolerant to imatinib or dasatinib or refractory or relapsed Ph+ ALL compared to the adult populations. It will also evaluate safety and activity of nilotinib as secondary objectives.
Interventions
Nilotinib capsules were delivered in bottles with dose strengths of 50mg, 150mg and 200mg. Patients were administered nilotinib 230 mg/m2 (per BSA) bid, orally, rounded to the nearest 50 mg (max single dose 400 mg) for 28 days (1 cycle) for up to 12 cycles prior to protocol amendment 3 and up to 24 cycles post amendment 3. Capsules were to be swallowed whole with water. Apple sauce (puréed apple) may have been used as a vehicle for dosing where capsules were not able to be swallowed whole with water.

| Number of Ph+ CML Participants With Cytogenic Response | minimum of 12 cycles (28 days per cycle) | Cytogenetic response was initially assessed as the percentage of Ph+ metaphases in the bone marrow (BM) and performed within 21 days prior to study entry. A major cytogenetic response (0% to 35% Ph+ metaphases test positive for the Philadelphia chromosome) combines both complete cytogenetic (CCyR) and partial cytogenetic response (PCyR). CCyR implies 0% Ph+ metaphases in the BM, PCyR is \> 0% to 35%, minor cytogenetic response (mCyR) is \> 35% to 65%, minimal response is \> 65% to 95% and no response is \> 95% Ph+ metaphases in the BM. |
