There are many types of clinical trials. Most commonly, they are divided into phase I, II, III, and sometimes IV. The phases refer to the phases of testing of a new drug in humans. Some our previous posts describe the various phases and discuss phase I trials and phase III trials in more detail. Here we would like to share with you page 47 from our book, where we provide a succinct summary of the advantages and disadvantages of each trial type, from the perspective of trial participants. The table shown below may not apply to every single trial, but it does give you a quick and straight forward basic guide.
