Pilot vs Pivotal

αυτό το γλωσσάρι:
Pilot Study
A pilot trial is used to obtain information, and work out the logistics and management, deemed necessary for further clinical trials. Although pilot trials are often unblind and use open-label medicines, they may also be single or double blind and may include tight control on all appropriate variables. The term “pilot” refers to the purpose of the trial (2).
Pivotal Study
Usually a phase III study which presents the data that the FDA uses to decide whether or not to approve a drug. A pivotal study will generally be well-controlled, randomized, of adequate size, and whenever possible, double-blind.
