Brief Summary:
In this study, the efficacy of nilotinib at 400 mg BID will be compared with imatinib at 400 mg BID in suboptimal molecular response patients. To determine study eligibility, suboptimal molecular response will be defined as patients who have achieved a complete cytogenetic response (CCyR) but have not achieved a MMR, after at least 18 months of treatment on first line imatinib therapy at a minimum dose of 400mg daily (Baccarani 2006).

Condition or disease Intervention/treatment Phase
Chronic Myeloid Leukemia Drug: Nilotinib, Imatinib Phase 3

Detailed Description:

Imatinib mesylate (imatinib) binds to the inactive conformation of Bcr-Abl tyrosine kinase suppressing the Ph+ clone in CML (Giles et al, 2005). It is effective in CML and is a major advance in therapy. With standard dose imatinib, the MMR and complete molecular response (CMR) rates are 35% to 40% and 6% to 10% respectively at 12 months. These surrogate endpoints have been associated with high long term survival rates (Kantarjian et al, 2004).

For patients who had a CCyR and MMR (defined as a reduction in Bcr-Abl transcript levels of at least 3 log at 12 months following imatinib therapy), the probability of remaining progression-free was 100 percent at 24 months, compared with 95% for patients achieved a CCyR but no MMR and 85% for patients who did not achieve a CCyR (P<0.001) (Hughes et al, 2003/Druker et al, 2006).

With continued doses of imatinib 400 mg/day, MMR at 24 months is 54% (IRIS SmPC data), however with high dose imatinib 800 mg/day, MMR may be 70%. Higher doses of imatinib improved the CCyR rates to 90% both in patients who failed prior IFN-alfa therapy and in those previously untreated (Cortes et al, 2005). Higher doses are expected to yield higher MMR rates at 24 months (Cortes et al, ASH 2004 poster). There is also a continued increase in the cumulative major/complete cytogenetic and molecular response rates with therapy, even after 2 years (Kantarjian 2004).

Nilotinib is a novel, oral tyrosine kinase inhibitor with improved potency compared with imatinib. In pre-clinical models of imatinib-sensitive CML cell lines, nilotinib was 20-50 times more potent than imatinib, and 3-7 times more potent in imatinib-resistant cell lines. In a Phase I dose-escalation trial [Study CAMN107A2101], 119 imatinib-resistant Ph+ CML and ALL patients were treated with single oral doses of nilotinib ranging from 50-1200 mg daily or 400 mg and 600 mg given twice daily. Nilotinib produced high hematologic and cytogenetic response rates of 92% and 53%, respectively (CCyR in 35%), in patients with chronic phase CML, who were resistant to imatinib. Nilotinib was found to have an acceptable tolerability profile (Kantarjian et al, 2005). Preliminary results from an ongoing Phase II study appear to confirm the efficacy and safety profile of nilotinib (Kantarjian et al, 2006).

Achievement of a major molecular response is an important short-term goal in CML therapy as it appears to predict for long-term event-free survival. This study is designed to compare the efficacy of nilotinib 400 mg twice daily with patients' maximum tolerated doses of imatinib (optimally 800 mg/day) in producing a major molecular response after 12 months of treatment in individuals previously not in major molecular remission. It will also examine the rates of major molecular and complete molecular response in each of the treatment arms, as achievement of these endpoints may also be of prognostic significance.
