To determine whether there is any significant difference between the duration of chronic phase and overall survival in patients given low-dose alpha IFN, to study toxicity profiles in the two arms of the trial as assessed by WHO criteria and by percentage of patients requiring dose reduction or abandoning therapy because of side effects, to study haematologic and cytogenetic response at six monthly intervals on treatment with either low-dose or high-dose alpha IFN.
