Abstract:
|
Stopping rules for toxicity are routinely used in phase II oncology trials. If the follow-up for toxicity is long, it is desirable to have a stopping rule that uses all toxicity information available, not only information from patients with full follow-up. Further, to prevent excessive toxicity in such trials, an enrollment rule is needed. The enrollment rule informs an investigator about the maximum number of patients that can be enrolled depending on the current enrollment and all available information about toxicity. We give recommendations on how to construct Bayesian and frequentist stopping and enrollment rules to monitor toxicity continuously in Phase II oncology trials with a long follow-up.
