Patients will commence taking oral nilotinib at 300mg twice daily for 3 months.

Brief summary
This study aims to determine the safety and efficacy of treatment with a tyrosine kinase inhibitor (TKI) and pegylated interferon in patients with previously untreated chronic myeloid leukaemia (CML).

Who is it for?
You may be eligible to join this study if you are aged at least 18 years and have been diagnosed with CML. You must have received no previous treatment for CML.

Trial details
All participants in this trial will commence treatment with the TKI oral nilotinib alone for 3 months. Provided the drug is tolerated, participants will commence injections of pegylated interferon at a dose of 30 micrograms per week. After a month of pegylated interferon and nilotinib treatment, and provided the pegylated interferon is tolerated, patients will escalate pegylated interferon treatment to a dose of 50 micrograms per week in combination with nilotinib. Participants will be assessed at regular timepoints until the end of the trial to determine the safety and clinical benefit of the treatments.
Treatment duration will be a minimum of 24 months.

This Phase II study will:

Investigate the survival benefit, the rate of remission and safety of the patients allocated to each group and compare the groups to eachother.
