This is the most common clinical trial design for confirma- tory therapeutic (Phase 3) trials. Subjects are randomised to Multicentre trials one of two or more treatment ‘arms’. These treatments will include the investigational drug at one or more doses, and Multicentre trials are carried out for two main reasons. First, one or more control treatments such as placebo and/or an they are an efficient way of evaluating a new medication, by active comparator. Parallel group designs are particularly accruing sufficient subjects in a reasonable time to satisfy useful in conditions that fluctuate over a short term, e.
