Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After patients meet eligibility criteria, they will be centrally randomized by computer (1:1:1:1) to one of three treatment groups or to a placebo control group. Patients will be assigned a randomization number. The patient and study personnel will be blinded as to which treatment the patient is receiving. Thirty-five patients will be randomized to each study group for a total of 140 patients. Randomization will be stratified by gender.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
140 sequential patients numbered 001 to 140 will be randomised. The randomization will be stratified by gender.
Masking / blinding
