Two-stage designs for cross-over bioequivalence trials. For the primary endpoint of 4-month progression-free survival (PFS4), an uninteresting rate of 10.9% obtained from historical controls and an anticipated rate of 28.9% were assumed. Cancer immunotherapy trial design with long-term survivors. Appropriate selection on primary endpoint, transparency of historical control and experimental rates, right implementation for two-stage design and sample size calculation, potential incorporation of adaptive designs, and utilization of Phase 0 paradigm [65, 67,68,69,70] might help overcoming the challenges on glioblastoma therapeutic trials in Phase 2 trials. Epub 2016 Sep 30. Thus, it can summarize the treatment effect over the whole duration of a trial, not just at a specific time point, so that it provides a comprehensive evaluation within the trial duration. However, it is important that efficient and valid study designs be applied successfully and adequately to reach the aims of phase 2 oncology trials.
