Administrative changes to a protocol that do not affect patient care or patient treatment, or a scientific change that does not substantively increase the patient’s risk/benefit ratio. Examples: Change of study coordinator, addition or deletion of a participating institution, or correction of an error. The revision date appears in the upper right hand corner of revised protocol pages.


Request for Applications. NCI sends out a request for studies dealing with their priority research areas. NCI sets aside money funding for these projects, should high quality applications get approved.
