Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation of study drug will be done Iteractive Voice Register System
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Random allocation sequence is done by computer generated system. When a patient is confirmed as eligible for the study, the Investigator will phone the IVRS system and the next treatment number available will be allocated for this patient's randomization number. The pharmacist will then prepare the study drug using the allocated subject number.
