Brief Summary

whether Nilotinib at the two sequential dosage forms will induce quicker and deeper response in those patients, and if FISH on PB (Peripheral blood) would be an effective way to monitor response compared to conventional cytogenetics on bone marrow (BM) sample

Conditions

Myeloid Leukemia, Chronic

NIlotinib , Suboptimal Response , Imatinib

Outcome Measures

Primary Outcomes (1)

• The primary efficacy variable of this study is the overall Major molecular response at 12 month after starting Nilotinib 300mg twice daily for patient who suboptimally responded to Imatinib as per the ELN guidelines

  12 Months

Secondary Outcomes (6)

• Rate of cytogenetic response (complete cytogenetic response CCyR and Major cytogenetic response MCyR) and Major molecular response MMR at 3, 6 and 12 months of starting Nilotinib in patients who had a suboptimal response on Imatinib.

  12Months

• Rate of CCyR at 6 months and MMR at 6 and 12 months from Nilotinib dose escalating to 400 mg BID.

  12 months

• Rate and duration of Complete Hematologic Response CHR.

  12 months

• Rate of CMR at 12 months of Nilotinib.

  12 months

• Comparison of FISH results with conventional cytogenetics at 3, 6 & 12 months.

  12

Other Outcomes (1)

• Mutational analysis for the patients with suboptimal response at the pre defined end points as per the ELN guidelines.

  12 months

Study Arms (1)

Nilotinib 300 mg

EXPERIMENTAL

Patients diagnosed with chronic myeloid leukemia receiving treatment of Imatinib 400 mg but show sub-optimal response on Imatinib therapy as per the ELN 2013 guidelines will be switched to Nilotinib 300 mg twice daily and will be assessed for timely. In the absence of safety concerns, nilotinib could be escalated to 400 mg twice daily if patients had not obtained any of the following milestones: 1. BCR-ABL1 transcript level ≤ 10% at 3 months; 2. CCyR at 6 months, 3. BCR/ABL1 ≤ 1% at 6 months 4. MMR at 12 months, or 5. if they showed loss of cytogenetic or molecular response or disease progression at any time. Failure and thus, stopping nilotinib will be considered if any of above milestones happened while on the 400mg twice daily dose.

Drug: Nilotinib 300 mg.

Interventions

Nilotinib 300 mg. DRUG

Patients diagnosed with chronic myeloid leukemia receiving treatment of Imatinib 400 mg once a day but are determined to be sub-optimally responding to Imatinib therapy as per the ELN 2013 guidelines will be switched to Nilotinib 300 mg BID and then will be assessed for therapy response. ELN guidelines 2013 for imatinib therapy response states as: Minor cytogenetic response mCyR or minimal response at 3 months (Ph+ metaphases in BM 35 to 95 %); BCR-ABL1 transcript \> 10% at 3 months; Partial cytogenetic response at 6 months Ph+ metaphases in BM 0to 35); BCR-ABL1 transcript is 1 to 10% at 6 months. Less than a major molecular response at \> 12 months; i.e (BCR-ABL1 0.1 -1%)
