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)
During the treatment period, subjects will be randomised to receive sodium selenate (VEL015 10 mg tds [total of 30 mg daily]), VEL015 320 mcg tds [total 960 mcg daily] or or placebo tds in a ratio of 2 to 1 to 1 respectively. Subjects will be randomised on Day 0 (Visit 2). At the time of randomisation, the subject will be assigned a unique Randomisation Number, which will be allocated in ascending order of random numbers based on the predetermined randomisation schedule, and according to their chronological order of inclusion in the study. Subjects will then be allocated a corresponding treatment kit labelled with the same treatment number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated randomisation schedule will be prepared by a statistician prior to the start of the study.
Masking / blinding
