A Phase II, Single Arm, Open Label Study of Treatment-free Remission in Chronic Myeloid Leukemia (CML) Chronic Phase (CP) Patients After Achieving Sustained MR4.5 on Nilotinib

A clinical research study to find out if it is safe to stop the drug nilotinib (Tasigna) in chronic myeloid leukemia (CML) patients. Patients who started treatment with imatinib (Gleevec) when they were first diagnosed with CML, then switched to nilotinib (Tasigna) for at least 2 years with the combined time on imatinib (Gleevec) and nilotinib (Tasigna) for at least 3 years and have very small amount of leukemia cells remaining after the nilotinib (Tasigna) treatment will qualify for the study.

1 Interventions

Name: nilotinib

Description: Nilotinib will be labeled as AMN107 and supplied as 150 mg and/or 200 mg hard gelatin capsule. Nilotinib will not be dosed by weight or body surface area. Nilotinib will be administered orally at 300 mg twice daily (BID) or 400 mg BID, at approximately 12 hour intervals, and must not be taken with food. The capsules should be swallowed whole with water. No food should be consumed for at least 2 hours before the dose is taken and no additional food should be consumed for at least one hour after the dose is taken. Patients who were previously treated with 400 mg BID, and required subsequent permanent dose reduction to 400 mg QD will be allowed to enter this study on the same dose, 400 mg once daily.

Type: Drug

nilotinib


Primary Outcomes

Description: TFR is defined as no confirmed loss of MR4 (Molecular response 4.0 log reduction from baseline) or loss of MMR (major molecular response) and no re-starting of nilotinib therapy within 12 months following cessation of nilotinib. Confirmed loss of MR4 is two consecutive BCR-ABL > 0.01% IS. Loss of MMR does not require confirmationTFR is calculated by dividing the number of patients with no documented confirmed loss of MR4, no documented loss of MMR and no re-starting of nilotinib therapy in the first 48 weeks after starting nilotinib TFR phase by the number of patients who entered nilotinib TFR phase.

Measure: Percentage of patients in Treatment Free Remission (TFR) within 48 weeks

Time: First 48 weeks following nilotinib cessation.

Secondary Outcomes

Description: TFR is defined as no confirmed loss of MR4 (molecular response 4.0 log reduction from baseline) or loss of MMR (major molecular response) and no re-starting of nilotinib therapy within 12 months following cessation of nilotinib. Confirmed loss of MR4 is two consecutive BCR-ABL > 0.01% IS. Loss of MMR does not require confirmation.TFR is calculated by dividing the number of patients with no documented confirmed loss of MR4, no documented loss of MMR and no re-starting of nilotinib therapy in the first 96, 144, 192, 264 weeks and within 6,7,8,9 and 10 years after starting nilotinib TFR phase by the number of patients who entered nilotinib TFR phase.

Measure: Percentage of patients in Treatment Free Remission (TFR) within 96, 144, 192, 264 weeks and within 6,7,8,9 and 10 years

Time: 96, 144, 192, 264 weeks and within 6,7,8,9 and 10 years following nilotinib cessation

Description: Kaplan-Meier (KM) estimation of PFS. PFS is measured from the date of start of nilotinib TFR phase (cessation of nilotinib) to the date of the earliest of the event: progression to AP/BC, or death from any cause. Patients not known to have recurred or died on or before the cut-off date for the KM analysis will have their PFS interval right-censored at the earlier of the date of their last assessment (cytogenetic, hematology or extramedullary) for patients who are still on study and at the date of last contact for patients are in follow-up.

Measure: Progression free survival (PFS) to Accelerated phase/Blast crisis (AP/BC) or death

Time: nilotinib cessation up to approximately 580 weeks

Description: TFS is measured from the date of the start of the nilotinib TFR phase to the date of the earliest of the following: loss of MMR, confirmed loss of MR4, re-start of nilotinib treatment, progression to AP/BC or death from any cause. Patients not known to have had any of the events or died on or before the cut-off date for the KM analysis will have their TFS interval right-censored at the earlier of the date of their last assessment (PCR, cytogenetic, hematology or extramedullary) for patients who are still on study and at the date of last contact for patients are in follow-up.

Measure: Treatment free survival (TFS)

Time: nilotinib cessation up to approximately 580 weeks

Description: Kaplan-Meier (KM) estimation of OS. OS is measured from the date of start of nilotinib TFR phase to the date of death from any cause. If a patient is not known to have died, survival will be censored at the date of last contact.

Measure: Overall survival (OS)

Time: nilotinib cessation up to approximately 580 weeks

Description: Descriptive statistics of BCR-ABL over time after re-start of nilotinib therapy. ABL= Abelson leukemia virus and BCR=Break point cluster region

Measure: Change in BCR-ABL (oncoprotein product of BCR-ABL fusion gene) transcripts after re-start of nilotinib therapy

Time: re-start of nilotinib up to approximately 48 weeks

Description: Percentage of patients who are in stable MMR (stable MMR=BCR-ABL ≤ 0.1% IS) at 48, 96, 144, 192, 240,288 ,336, 384, and 432 weeks after achievement of that response in the nilotinib re-initiation phase for 48, 96, 144, 192, 240,288 ,336, 384, and 432 weeks is calculated by dividing the number of patients achieving MMR any time during the nilotinib re-initiation phase and having the same response at 48, 96, 144, 192, 240,288,336, 384, and 432 weeks after the first achievement of MMR, irrespective of whether there is loss of MMR in between, by the number of patients who achieved MMR at any time during the nilotinib re-initiation phase

Measure: Percentage of patients with stable MMR in nilotinib re-initiation phase

Time: start of nilotinib in re-initiation phase up to approximately 432 weeks
