Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation - patients will be randomised through phone and fax via IVRS (Interactive Voice Response System).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be assigned to one of four treatment groups according to a computerised randomisation schedule. The clinical site will then randomise patients according to drug kit number generated via an Interactive Voice Response System (IVRS)
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
