I have just had a look at the NICE website and see that there have been consultations in December and January about the remit and scope of an appraisal for dasatinib and nilotinib. there is a further 'scoping workshop' due to take place on Feb 8th. (see link below and scroll down page until you come to chronic myeloid leukaemia)
i have emailed the contact at NICE asking for infromation on dates and likely timelines for this appraisal. i will update you when I hear back from her.
