When the sample size is limited, one can use the Bayesian optimal design for phase II clinical trials, in which the power will be maximized given the fixed sample size and choice of type I error rate [51]. Glioblastoma clinical trials: current landscape and opportunities for improvement. An official website of the United States government. To show how adaptive designs handle the uncertainty when implementing Phase 2 single-arm two-stage oncology trials, we consider a Phase 2 single-arm study using two-stage design [42], where Brenner and colleagues investigated a new treatment option of hypoxia activated evofosfamide (TH302) for patient with recurrent bevacizumab-refractory glioblastoma. Among 29 reviewed articles, majority study types were glioblastoma (n=20, 69% over high-grade glioma, n=9, 31%) with recurrent patients (n=23, 79% over newly diagnosed patients, n=6 and 21%) and adult patients (n=22, 76% over pediatric population, n=7, 24%). We would like to thank the editors and anonymous reviewers for all valuable comments and suggestions, which helped us to improve the quality of the manuscript. Article Kim and Wong (2022) recently introduced novel designs that compromise on the two optimality criteria using the spatial information on the first stage's required sample size and the total required sample size [52]. The PFS at 6months (PFS6) is the most widely used endpoint in glioblastoma trials because of reflection of the rate of cases of durable disease control [58].

Most trials (n=22, 76%) successfully provided all key information while 7 trials (24%) failed to provide at least one key information (Six trials failed to provide two types of error rates, four trials failed to provide two response rates, and three trials failed to provide two or more than two key results from the sample size calculation). 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]. Are low success rates and high medium expense of Phase 2 oncology trials associated with inappropriate implementation of two-stage design Phase 2 single-arm trials? Please remove one or more studies before adding more. Among examined 29 trials, 12 trials (41%) appropriately provided key input parameters and sample size results from two-stage design implementation.

Optimized image-based surrogate endpoints in targeted therapies for glioblastoma: a systematic review and meta-analysis of phase iii randomized controlled trials. In this phase 2 study, we demonstrated that treatment with single-agent PD-1 inhibitor was safe and associated with a 3-month OS of 60% in a heavily pre-treated Cerebrospinal fluid neurofilament light chain as a potential prognostic biomarker for leptomeningeal metastasis. Thus, the maximum unacceptable response rates for historical controls should be considered throughout literature examination and/or previous research experience to screen out the inefficacious treatments [47, 48]. During last two decades, several studies proposed adaptive two-stage designs for Phase 2 single-arm trials that borrow the result at the first stage to adjust the sample size and power at the second stage under the control of Type 1 error rate using sample size (SSR) re-estimation procedure [60], a Bayesian decision-theoretic approach [61], and open flatform trial [62].
