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%]). Privacy The systematic review was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA)-statement. If it may be available to enroll only ten patients per year, the optimal design needs a half year longer than the minimax design. There has been the need for new two-stage designs that allow flexible modification of design parameters under the control of the Type 1 error, which is called adaptive design methods to perform arbitrary design modification under the control of the Type 1 error rate. Clin Cancer Res. The https:// ensures that you are connecting to the Phase II study of bevacizumab and temsirolimus combination therapy for recurrent glioblastoma multiforme. 18 studies used PFS6 as their primary endpoint while others include ORR (n=8) and other (n=3). 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]. Neurology 33, 15651572 (1983). J. Neurooncol. Pharm Stat. We show that Simon's two-stage designs for efficacy studies can be similarly used to design a two-stage safety study by modifying some of the design parameters.

Would you like email updates of new search results? Phase II clinical trials with time-to-event endpoints: optimal two-stage designs with one-sample log-rank test. Let us now assume that 4 (36.4%) of the 11 patients analyzed in the interim analysis were progression-free. 133, 419427 (2017). The two-stage design tests efficacy using the number of responses at the end of first stage of the trial and only if an efficacy threshold is met can the trial proceed to the second stage. Thus, the key input parameters (\(\alpha , \beta , {p}_{0}, {p}_{1}\)) and output results (\({n}_{1}, n, {r}_{1}, r\)) were investigated to assess the appropriate usage and report of the two-stage phase 2 trials. government site. -. Phase II open-label study of nintedanib in patients with recurrent glioblastoma multiforme. Multicenter, single arm, phase II trial on the efficacy of ortataxel in recurrent glioblastoma. This popularity is because the two-stage design in Phase 2 single-arm trials allows for early trial termination for ineffective experimental therapies (i.e., futility). Bookshelf Kieser M, Rauch G. Two-stage designs for cross-over bioequivalence trials. 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 Table 1 shows the summary of the included studies for Phase 2 single-arm two-stage clinical trials in glioblastoma. The percentage of patients who experienced one (or more) grade 3 or higher adverse events at least possibly related to treatment was 40%, the most frequent being hyperglycemia (n = 6), nausea (n = 7) and vomiting (n = 7). Google Scholar. 2020 Aug;26(8):1309. doi: 10.1038/s41591-020-0978-1. Figure1 shows flow diagram (PRIMA) of the literature search and study selection process. In The primary endpoint was overall response rate (ORR) centrally assessed by an independent efficacy assessment committee (IEAC). 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. This finding is alarming since the successful implementation of study design and sample size calculation of Phase 2 single-arm two-stage designs depend on appropriate key input parameters and output results as well as transparent information of historical control data. 2012;11(3):2419.

Since the two-stage design of Phase 2 trials aims to make a conclusion of go or no-go to the next second stage, the sample size calculation of two-stage designs produces the number of patients in first stage (\({n}_{1}\)) and the response number which is eligible to move to the second stage (\({r}_{1}\)). By doing so, the chance to capture the effectiveness of a treatment can be increased. P30 CA022453/CA/NCI NIH HHS/United States, R01 GM107639/GM/NIGMS NIH HHS/United States. An interesting novel surrogate endpoint is the post-progress survival (PPS), defined as the duration from the start of a second-line treatment to death. Phase 2 study of Pomalidomide (CC-4047) monotherapy for children and young adults with recurrent or progressive primary brain tumors. Trials involving several arms, or randomized Loncastuximab tesirine has substantial single-agent antitumour activity and produces durable responses with an acceptable safety profile, potentially offering a new therapeutic option for heavily pretreated patients with relapsed or refractory DLBCL. Methods: In this open-label, single-arm, single-center, exploratory phase II study, 10 patients (20 eyes) received EG-Mirotin once a day (3 mg/1.5 mL sterile saline) for 5 days and were evaluated for ischemic index changes and safety.

An increasing fraction of patients with metastatic cancer develop leptomeningeal dissemination of disease (LMD), and survival is dismal1-3. 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 (\({p}_{0}, {p}_{1}\)). Such an unexpected situation cannot be appropriately handled with the current system of two-stage designs because current designs require to prespecify the design information like sample size for each stage and stopping rules in the study protocol.

We conducted the prospective, open-label, single-arm, phase 2 TUXEDO-1 trial. 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. 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.

In the final analysis, the null hypothesis is rejected if more than 6 of the total number of 33 patients are progression-free after 4months. Englert S, Kieser M. Adaptive designs for single-arm phase II trials in oncology. In this manner, the two-stage designs allow stopping of a futile trial early.
