De- Escalation and Stopping Treatment of Imatinib, Nilotinib or sprYcel in Chronic Myeloid Leukaemia

Summary

The purpose of this study is to investigate whether some patients with excellent responses to chronic myeloid leukaemia (CML) treatment are being overtreated, and can remain well on either a lower dose of treatment or without treatment at all. The dose of imatinib (Glivec), nilotinib (Tasigna) or dasatinib (Sprycel) treatment will initially be cut to half the standard dose for 12 months, and then treatment will be stopped completely for a further two years. The trial information will also help to develop a de-escalation and stopping strategy for future newly diagnosed CML patients in the next British national CML study (to be known as SPIRIT3).
