Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be preliminarily screened via on-line form and then by telephone, then requested to attend an information and question session where they will be informed of the trial process and asked to provide their consent prior to further involvement in the trial. Consenting participants will have a case history taken and undergo a brief medical assessment. The blinded product is supplied to the clinic staff and they allocate participants with a labelled trial product in numerical order (between 1 and 150) as they are enrolled.

Randomisation will be performed by the sponsor using Random Allocation Software, version 1.0, May 2004. Randomisation will be based on a total of 150 subjects, randomly allocated into either Active 1, Active 2 or Placebo arm of equal numbers of subjects (n=50 for each group).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is performed by the sponsor using Random Allocation Software, version 1.0, May 2004. Randomisation is based on a total of 150 subjects, randomly allocated into either Active 1, Active 2 or Placebo arm of equal numbers of subjects (n=50 for each group).
