Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The allocation sequence will be by sequentially numbered, opaque, sealed envelopes and will be generated by the data management team at The George Institute for Global Health
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients will be allocated to treatment (placebo or active study drug) using computer-generated random numbers. There will be no stratification.
