single arm phase 2 trial

Among examined 29 trials, 12 trials (41%) appropriately provided key input parameters and sample size results from two-stage design implementation. To improve test power, we proposed a new weighted one-sample log-rank test and provided a sample size calculation formula for designing trials. 2019 Dec 1;25(23):6986-6994. doi: 10.1158/1078-0432.CCR-19-0711.

Diffuse Large B-Cell Lymphoma (DLBCL): Early Patient Management and Emerging Treatment Options. This single-arm phase II interventional study aims to assess disease response to, and toxicity of, a Epub 2022 Dec 6. 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]. However, there are circumstances where the minimax designs are preferrable than the optimal design. Wu X, Wu C, Liu F, Zhou H, Chen C. A generalized framework of optimal two-stage designs for exploratory basket trials. The median follow-up of surviving patients was 6.3 months (range, 2.2-12.5 months). The other three trials used two-stage designs like Inadmissible design, Fleming and Gehan designs. J Neurooncol. Anand S, et al.

In this systematic review, we have examined 29 studies from Phase 2 single-arm two-stage trials in glioblastoma to assess the appropriateness and transparency of the study design and sample size calculation of Phase 2 single-arm two-stage trials in glioblastoma.

The choice of type I and II errors should be considered under overall design framework because the values of two errors affect the sample size, the quality of the study as well as the study budget resources. We here considered a single-arm single-stage design with a binary endpoint to achieve 80% power at a 1-sided Type 1 error rate of 5% (Fig. Study design input information and output results from sample size calculation related to two-stage design implementation were examined. eCollection 2022.

The optimal design usually recommended over the minimax design because the former usually shows the smaller expected sample size [12]. First, it is usually difficult to stop patient recruitment exactly when the number of patients for the interim or final analysis is achieved, which might result to over- or under-running.

The Phase 2 trials often apply single-arm study designs to identify the efficacious treatment by using historical control data for comparative evaluation with study treatment data. In this research, we proposed a piecewise proportional hazards cure rate model with random delayed treatment effect to design single-arm phase II immunotherapy cancer trials. Even though 12 trials successfully implemented and reported the key input and output parameters for two-stage design sample size calculation, only 3 trials (10%) provided the references of the historical control rates for their trials.
