The implementation of adaptive clinical trial methods, however, requires greater planning and simulation compared with a more traditional design, along with more advanced administrative infrastructure for trial execution.
These negative results may be related to the drug itself, the protocol in terms of patient selection and/or end points, and/or the trial execution.
While rules and regulations create an accepted factor in delaying trial execution, protocol issues and procedures are more often a delay factor than needed, particularly in industry-sponsored studies.
Erwin Rommel during World War II was found to have foreknowledge of the July 20 Plot on Hitler's life and was threatened with public trial, execution, and reprisals on his family unless he took his own life.
This low absolute incidence combined with high morbidity, poor response rates and short survival times pose practical problems for clinical trial execution, particularly if therapy is anticipated to target a molecularly-defined subset of tumors.
Second, CTS requires a trial execution model.
JTE, MM, SR, JS and IN contributed to trial execution.
MK assisted with the trial execution at the Yale site.
The trial execution model concerns other random events such as dropout rate, or other events related to trial execution, which may have an impact on the trial outcome.
In the trial execution phase it can be used to identify data elements for re-use.
