A randomized control trial comparing oral THU-decitabine to nicotinamide (1:1 randomization), and then comparing the effects of the combination of nicotinamide with THU-decitabine vs either treatment alone. Treatment with each agent alone is for 12 weeks followed by the combination for a further 12 weeks. Patients have the option to enter an extension phase of combination treatment for an additional 24 weeks (total of 48 weeks)
