MeSH Assuming a true rate of 28.9%, additional 10 patients are sufficient to achieve 80% power. The .gov means its official. 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]. We extracted disease type and setting, population, therapeutic drug, primary endpoint, input parameters and sample size results from two-stage designs, and historical control reference, and study termination status. Terms and Conditions, In these cases, researchers must use endpoints like response ratethat can demonstrate clinical impact in the absence of direct comparison data. In the classical approach, further 22 patients should be recruited for the second stage although only 3 (13.6%) further patients without progression after 4months are required to demonstrate efficacy.

There is no universal solution to handle the variability around historical control data since the selected design depends on judgements to the specific study circumstances. J Neurooncol. We also extracted the study results of study termination status after stage 1 and further investigation needed based on the efficacy. To improve test power, we proposed a new weighted one-sample log-rank test and provided a sample size calculation formula for designing trials. 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]. 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.

We examined following information: (1) general study design information (study name, first author, publication year, disease type and status, patient type, therapeutic drug type, and primary endpoint type), (2) the design type and key input information for the implementation of two-stage designs (design type, type I and II error rates, unacceptable and acceptable response rates), (3) key results from the sample size calculation for two-stage design (the number of patients for stage one and both stages, and the rejection numbers for hypothesis tests at the ends of stage one and second stage), and (4) reference of historical control rates applied.
