While Phase 3 trials are frequently randomized in order to provide more precise data on safety and effectiveness outcomes, a Phase 3 trial might use a single arm if a small target population makes conducting a randomized trial impractical.

Our simulation study showed that the proposed log-rank test performs well and is robust of misspecified weight and the sample size calculation formula also performs well. Careers. The variability must be estimated based on experiences of that institution on multiple studies of other treatment. 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. The two types of errors (\(\alpha , \beta\)) and unacceptable and acceptable response rates (\({p}_{0}, {p}_{1}\)) are key input information for successful sample size calculation of two-stage design.

Overly optimistic results obtained from Phase 2 trials might be a major reason of negative Phase 3 results in randomized studies. The rapid trials and ethical reasons generally lead the single-arm trials to be performed with interim analyses for possible early termination of the trials. PMC Neuro Oncol. Oncoimmunol. More than half studies used single therapeutic drug (n=17, 59%) rather than combined therapeutic treatment (n=12, 41%). 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].

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). 2018;15(2):14958.

Trippa L, et al. Phase 2 trial of dasatinib in target-selected patients with recurrent glioblastoma (RTOG 0627). 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). Invest New Drugs. Most trials (n=22, 76%) successfully provided all key information while 7 trials (24%) failed to provide at least one key information (Six trials failed to provide two types of error rates, four trials failed to provide two response rates, and three trials failed to provide two or more than two key results from the sample size calculation). 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. Phase 0 clinical trials in oncology new drug development. Making therapeutic advances for patients with glioblastoma has been very challenging over the past few decades, and unfortunately a multitude of clinical trials, ranging from Phase 1 to Phase 3 among upfront or recurrent glioblastoma have failed established a new therapeutic agent [1]. The purpose of this study is to evaluate the efficacy and safety in patients with FGFR2-Rearranged unresectable or metastatic intrahepatic cholangiocarcinoma who failed prior therapy Arms and Interventions Arm: Experimental Drug ICP-192 Outcome Measures 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. Phase II study of Dovitinib in recurrent glioblastoma. The Bayesian basket design for genomic variant-driven phase II trials. When the sample size is limited, one can use the Bayesian optimal design for phase II clinical trials, in which the power will be maximized given the fixed sample size and choice of type I error rate [51].

Clipboard, Search History, and several other advanced features are temporarily unavailable. Nonetheless, none has examined the usage for published articles that had applied the two-stage designs in Phase 2 single-arm trials in brain tumor. Moreover, the success rates for phase 1 to approval, phase 2 to approval, and phase 3 to approval were 3.4%, 6.7% and 35.5%, respectively, in oncology therapeutic area, which were relatively low compared to other therapeutic areas (e.g., 25.5%, 32.3%, and 62.2% of cardiovascular disease therapeutic area and 25.2%, 35.1%, and 75.3% of infectious disease therapeutic area) [3]. 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. In this 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).

Diffuse Large B-Cell Lymphoma (DLBCL): Early Patient Management and Emerging Treatment Options. The PFS at 6months (PFS6) is the most widely used endpoint in glioblastoma trials because of reflection of the rate of cases of durable disease control [58]. Second, if the patient accrual rate is low, the minimax design is more attractive because it requires the smaller number of patients in total (n). The sample size calculation for the two-stage designs is determined based on the historical control rate and difference between the two rates (\({p}_{0}, {p}_{1}\)).
