Detailed Description: This is an international, single-arm, multicenter phase 2 trial, in Le Rhun, E. et al. Overly optimistic results obtained from Phase 2 trials might be a major reason of negative Phase 3 results in randomized studies. Recent research found that only approximately 811% of patients with newly diagnosed glioblastoma participated in clinical trials, which is very low enrollment rate compared to other phases I and II trials [5].

TACE-HAIC Plus Lenvatinib for Patients With Unresectable HCC: an Open-label, Single-arm, Phase 2 Trial (Thalen) The safety and scientific validity of this study The adaptive design allows the incorporation of interim results to adjust the second stage designs under still controlling the Type 1 error rate and may provide economic benefit by reducing the waste of resources (Fig. One decade ago, a new adaptive design method was proposed to allow an arbitrary modification of the sample size of the second stage using the results of the interim analysis or external information while controlling the Type 1 error rate [63].

Comput Stat Data Anal. Given the type I and II error rates and the proportion of adverse events experienced in the first stage cohort, we prescribe a procedure whether to terminate the trial or proceed with a stage 2 trial by recruiting additional patients. Burzynski SR, et al. Disease population was categorized into three diseases of glioblastoma (n=20), high-grade glioma (n=8), and brain metastasis from glioblastoma (n=1), two settings of recurrent status (n=23) and newly diagnosed status (n=6), two patient types of adults (n=23) and child or pediatric (n=6), and two therapeutic drug types of single (n=17) and combination (n=12). 2018 Sep;17(5):541-554. doi: 10.1002/pst.1878. 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 Phase II trials in journal of clinical oncology.

WebARTICLE Clinical Trials 2011; 8: 260269 Quantitative evaluation of single-arm versus randomized phase II cancer clinical trials Gregory R Ponda,b and Saqib Abbasia Background There is a debate among cancer researchers about the use of single-arm or randomized phase II clinical trial designs; however, there is limited published IEAC-assessed median DOR was not reached (NR; 95% CI, 1.87 months to NR).

Adult T-cell leukemia/lymphoma (ATL) is an aggressive non-Hodgkin lymphoma with poor prognosis and few treatment options for patients with relapsed, recurrent, or refractory disease. These factors are recommended to be considered carefully when planning a Phase 2 single-arm study. Lassen U, et al. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. Valemetostat demonstrated promising efficacy and tolerability in heavily pretreated patients, warranting further investigation in treating R/R ATL. Several important topics related to the design issues will be followed to handle the design issues by increasing the precision of efficacy from targeted therapeutic trials of Phase 2 two-stage designs in brain tumor.
