Comparative StudyDose-finding designs in pediatric phase I clinical trials: comparison by simulations in a realistic timeline framework.
Usual dose-finding methods in oncology are sequential. Accrual is suspended after each group of patients to assess toxicity before increasing the dose. An adapted Continual Reassessment Method (CRM) and Rolling 6 (R6) method, designed to avoid this suspension of accrual in pediatric oncology, are compared with the traditional 3+3 design. ⋯ These new methods can reduce the number of skipped patients, but only provide limited gain in terms of ability to select the right dose. New designs are needed.
