The synonyms and closely related words include phase 2 for phase II trials, GBM or high-grade glioma for glioblastoma, and 2-stage, Simon, Fleming or Gehan for two-stage design. Kalpathy-Cramer J, et al. Such a study design may not be suitable for immunotherapy cancer trials, when both long-term survivors (or even cured patients from the disease) and delayed treatment effect are present, because exponential distribution is not appropriate to describe such data and consequently could lead to severely underpowered trial. 2004;23(4):5619.

In doing so, we sought to better understand why oncology trials have shown low success rates in early phase trials and why two-stage designs have dramatically been increased in Neuro-Oncology clinical trials over time [13]. Chu Y, Yuan Y. MeSH Simons two-stage designs have been widely used for single-arm trials in glioblastoma since Simon proposed his landmark paper in 1989 [6], and has been extended with various methodological development like the basket trials [7, 8] and Bayesian approach [9,10,11].
