single arm phase 2 trial

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). Chu Y, Yuan Y. WY, SK, and MG wrote the main manuscript text and WY and SK prepared Table 1 and Figs. The followings were key words for the literature search as index terms or free-text words: phase II trials, glioblastoma, and two-stage design.

Better understanding on the study drug information and targeted molecular information might help the understanding of why the two-stage trials had been terminated after the stage 1 and ineffective after successful completion of both stages.

For instance, in Case 3, the 10% and 50% reductions of p0 are 0.45 (=0.50.9) and 0.25 (=0.50.5). To avoid this temptation, which poses a potential risk to patients, investigators should practice transparency by citing historical data sources used in the study protocol. The choice of type I and type II errors is highly important since researchers need to assure that potentially effective therapy is not abandoned and at the same time the insignificant studies with very small marginal effects should not be advanced to subsequent phase III studies.

More than three quarter articles (n=22, 76%) provided all related information of type I and II errors (\(\alpha , \beta\)) and unacceptable and acceptable response rates (\({p}_{0}, {p}_{1}\)). 2013;10(5):72034. And 7 trials were used with (1) 5% and 20% (2) 10% and 10% as their type 1 and 2 errors respectively. Pembrolizumab is safe and feasible and displays promising activity in patients with LMD.

Let us assume that the result of a two-stage design indicates 18 and 23 in total patients for the minimax and optimal respectively. MeSH Yoo, W., Kim, S., Garcia, M. et al. Grade 3 TEAEs included thrombocytopenia, anemia, lymphopenia, leukopenia, and neutropenia. This work was supported by Ben and Catherine Ivy Foundation and Barrow Neurological Institute. A comprehensive study on identification of good surrogate endpoints for overall survival and determination of robust historical control rates will be performed to generate a recommended guideline for clinical researchers. The most common grade 3 or higher treatment-emergent adverse events were neutropenia (37 [26%] of 145 patients), thrombocytopenia (26 [18%]), and increased gamma-glutamyltransferase (24 [17%]). 2012;110(1):1118. Breslow NE. Patients received valemetostat 200 mg/day until progressive disease or unacceptable toxicity. WebThe trial ended after accrual completion; the database lock was Dec 31, 2019. HHS Vulnerability Disclosure, Help Banerjee A, Tsiatis AA. Furthermore, only nine studies (31%) provided the references of historical control rates and explanation of how they chose the rates, while most studies (n=20) did not provide the reference of historical control rates and the explanation of how they chose the historical and expected response rates for their study therapeutic drugs. Estimated research and development investment needed to bring a new medicine to market, 20092018. Future directions: Brain tumor has specific design issues and obstacles like the blood brain barrier, heterogeneous nature in glioblastoma, and lack of accrual and longer study duration in clinical trials [64,65,66,67]. doi: 10.1016/S2352-3026(22)00072-2. 2014;30(12):205161.

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. As output results, the two-stage designs (Optimal, Minimax, and Admissible designs) produce following key outputs of the number of patients (\({n}_{1}\) and \({n}_{2}\)) for stage 1 and both stages and the rejection numbers (r and \({r}_{1}\)) for both stage 1 and both stages respectively.

Accessibility 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. Among appropriately implemented 12 trials, discouragingly only 3 trials (10%) explained the reference information of historical control rates. Cancer immunotherapy trial design with cure rate and delayed treatment effect. Cancers (Basel). Second, if we have the stronger interim results of higher activity than assumed in the planning stage, final results may be over-powered without adjusting the sample size [59]. Recent research reported that the success rate in proceeding from Phase 2 to Phase 3 was the lowest among all three rates of Phase 1 to 2, Phase 2 to 3, and Phase 3 to approval (e.g., 29.7%, 20.3%, and 35.5% for oncology and 35.2%, 27.4%, 59% for overall) [2]. 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 Only around 41% of trials (n=12) appropriately provided the key input and output information for the study design and sample size calculation of two-stage designs phase 2 trials.

Twenty-five patients (median age, 69.0) with a median of 3 prior lines of therapy were enrolled; 24 had prior mogamulizumab treatment. Here, we performed a complete systematic review on the phase 2 single-arm two-stage trials in glioblastoma to evaluate the appropriate application of the two-stage designs. Patients pretreated with mogamulizumab had an ORR of 45.8% (4 complete and 7 partial remissions). Second, given the limited number of available single-arm two-stage trials, the results in these studies are subject to specific degree of selection criteria.

The underestimation rate of p0 was ranged from 0.1 (i.e., 10% reduction) to 0.5 (i.e., 50% reduction). A complete systematic review and discussions for overcoming design issues might be important to better understand why oncology trials have shown low success rates in early phase trials. Bethesda, MD 20894, Web Policies Disclaimer, National Library of Medicine Federal government websites often end in .gov or .mil. 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. Experimental arms, which receive an experimental drug, are compared with control arms, which can receive an active comparator (another therapy used to treat the same condition as the experimental therapy), a placebo comparator (an inactive therapy), a sham comparator (an inactive therapy made to look identical to the active therapy), or no intervention. FOIA Dowlati A, Crosby L, Remick SC, Makkar V, Levitan N. Lung Cancer. IEAC-assessed median DOR was not reached (NR; 95% CI, 1.87 months to NR).

Protracted low doses of temozolomide for the treatment of patients with recurrent glioblastoma: a phase II study. We systematically reviewed published single-arm two-stage Phase 2 trials for patients with glioblastoma and high-grade gliomas (including newly diagnosed or recurrent). We conduct a multi-center single-arm phase 2 trial to test the efficacy and safety of an oral neoadjuvant therapy with pyrotinib, letrozole and dalpiciclib (a CDK4/6 If advanced to stage 2, the number of patients in both stages (\(n\)) and the response number (\(r\)) of the efficacy for the Phase 2 trial are provided. 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]. A common practice in sample size calculation is to assume that the event time in the new treatment follows exponential distribution. J Clin Oncol.
