every visit: patients will be seen weekly for the first two weeks and then every fortnight thereafter to 8 weeks. When they enter the open label trial, they will be seen weekly for the first two weeks and then fortnightly to the end of the trial (that is after 8 weeks). Therefore, there will be 5 visits during the randomized controlled trial (RCT) phase and five visits during the open-label trial and 1 year follow up
Primary outcome [3] 5779 0

Timepoint [3] 5779 0
every visit: patients will be seen weekly for the first two weeks and then every fortnight thereafter to 8 weeks. When they enter the open label trial, they will be seen weekly for the first two weeks and then fortnightly to the end of the trial (that is after 8 weeks). Therefore, there will be 5 visits during the RCT phase and five visits during the open-label trial and one year follow-up.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Provided that an individual meets the inclusion criteria and does not meet exclusion criteria, the person is allocated the next available number. All pills (ie active ingredient or placebo) have been pre-packaged by the pharmacy who holds the randomization code. A sealed envelope is contained within each pill package only to be opened in an emergency (ie patient deteriorates significantly).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomization was done using software produced by www.randomization.com. Four lists were generated and the pharmacy randomly chose one list to use for the randomization.
