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. Eur J Cancer. Analysis of survival data under the proportional hazards model. 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. Inclusion of non-inferiority analysis in superiority-based clinical trials with single-arm, two-stage Simon's design. J. Clin. In addition, the several trials provided wrong results from sample size calculation even if they reported all related key information for two-stage design implementation (not shown in table).

Bethesda, MD 20894, Web Policies Adaptive two-stage designs in phase II clinical trials. A common practice in sample size calculation is to assume that the event time in the new treatment follows exponential distribution. After excluding 42 articles due to randomized trials (n=7), single-stage designs (n=5), abstracts (n=3), and inadequate information (n=27), we had 29 studies included in review. Bayesian hierarchical modeling of patient subpopulations: efficient designs of Phase II oncology clinical trials. OPTIM-ARTSAn adaptive phase II open platform trial design with application to a metastatic melanoma study. 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]. Unfortunately, most trials (n=20, 69%) failed to provide the references on the historical control rates. Unable to load your collection due to an error, Unable to load your delegates due to an error.

The .gov means its official. and transmitted securely. Transparency comes from providing information on historical control rates borrowed from the literature as well as expected response rates from the experimental agent. 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. An armof a clinical trial is a group of patients receiving a specific treatment (or no treatment). Valemetostat 200 mg orally once The therapeutic areas in oncology and immune-modulatory drugs were the most expensive, with a median of $2.8 billion and a mean of $4.5 billion [3]. To illustrate the effect of underestimated historical control on the study power, we carried out a simulation study as follows. Chu Y, Yuan Y. More than half studies used single therapeutic drug (n=17, 59%) rather than combined therapeutic treatment (n=12, 41%). Eur J Clin Pharmacol. Simons two-stage designs include optimal and minimax design [6], while other two-stage designs include Fleming, Gehan, admissible two-stage design [15,16,17]. The Bayesian basket design for genomic variant-driven phase II trials. Hargrave D, et al. J Neurooncol. Eur J Cancer. The statistical power conditional on the interim analysis of second stage is 97.3% for the true rate of 28.9%, which is far beyond the originally pre-specified 80% of power. Among appropriately implemented 12 trials, discouragingly only 3 trials (10%) explained the reference information of historical control rates. WebEVER-132-001 (NCT04454437) was a multicenter, single-arm, Phase IIb study in Chinese patients with mTNBC who failed 2 prior chemotherapy regimens. Modified Simon's minimax and optimal two-stage designs for single-arm phase II cancer clinical trials. Pharm Stat. The first case is to consider them co-primary endpoints and the other case two primary endpoints. If the parameters of two-stage designs (\({p}_{0}, {p}_{1}\)) are given, there are infinitely many two-stage designs satisfying the (\({\alpha }^{*}, {\beta }^{*})\) condition. Stat Med. We provide a real-life application and a free R package gen2stage to facilitate direct use of such two-stage designs in a safety study. Right implementation for two-stage design and sample size calculation, transparency of historical control and experimental rates, appropriate selection on primary endpoint, potential incorporation of adaptive designs, and utilization of Phase 0 paradigm might help overcoming the challenges on glioblastoma therapeutic trials in Phase 2 trials. Unable to load your collection due to an error, Unable to load your delegates due to an error. Due to duplicates (n=10), 71 articles were eligible to assess. 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. Lin Y, Shih WJ. Only three studies have been completed for both stages and two out of the three completed studies had shown the efficacy. Bayesian single-arm phase II trial designs with time-to-event endpoints. 2022;28(4):594602. Therefore, the two-stage design in phase 2 trials provide a proof of concept that an experimental treatment is effective with small-sample efficacy evaluation before moving toward to bigger and confirmatory large-sample phase 3. 2022 Dec 26;56:101779. doi: 10.1016/j.eclinm.2022.101779. Some clinical trial designs, such as the lung cancer master protocol design, allow for several experimental drugs to be tested simultaneously. 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 This phase 2 study assessed the efficacy and safety of the dual EZH1 and EZH2 inhibitor valemetostat in patients with R/R ATL. Biom Biostat Int J. Careers. 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.

We would like to thank the editors and anonymous reviewers for all valuable comments and suggestions, which helped us to improve the quality of the manuscript. Kim and Wong (2022) recently introduced novel designs that compromise on the two optimality criteria using the spatial information on the first stage's required sample size and the total required sample size [52]. The determinatio of the number of patients required in a preliminary and a follow-up trial of a new chemotherapeutic agent.

Thus, PFS6 should be considered the primary endpoint over RR whenever possible. J Neurooncol. Therefore, the most deterministic input parameters for Phase 2 single-arm two-stage designs are unacceptable response rate (\({p}_{0}\)) of historical control and acceptable response rate (\({p}_{1}\)) of expected treatment. J Clin Neurosci. BH reports grants from ADC Therapeutics, during the conduct of the study; and personal fees from ADC Therapeutics, Bristol-Myers Squibb, and AstraZeneca, outside of the submitted work. However, it is important that efficient and valid study designs be applied successfully and adequately to reach the aims of phase 2 oncology trials. Neurol. Diffuse Large B-Cell Lymphoma (DLBCL): Early Patient Management and Emerging Treatment Options. 2010;28(11):193641. 2012;11(3):2419. The unacceptable historical control rate should be a maximum rate while the acceptable expected treatment rate should be a minimum rate in order not to be overly optimistic for the Phase 2 clinical trials. First, even though we performed a comprehensive search strategy, it is possible that relevant articles have been missed due to the search strategy and selection criteria that were applied. Bookshelf The synonyms and closely related words include phase 2 for phase II trials, GBM or high-grade glioma for glioblastoma, and 2-stage, Simon, Fleming or Gehan for two-stage design. 2018;15(2):14958. 2021;11:660892. The primary endpoint was rate of overall survival at 3 months (OS3). Patients received valemetostat 200 mg/day until progressive disease or unacceptable toxicity. Trials involving several arms, or randomized The site is secure. Cancer immunotherapy trial design with cure rate and delayed treatment effect. Listing a study does not mean it has been evaluated by the U.S. Federal Government. [37] used Simons two-stage optimal design to evaluate the target PFS6 of 35% against the null PFS6 of 20% to achieve 90% power at a 1-sided 10% level, resulting in the required sample size of 58 patients. Among 29 reviewed articles, majority study types were glioblastoma (n=20, 69% over high-grade glioma, n=9, 31%) with recurrent patients (n=23, 79% over newly diagnosed patients, n=6 and 21%) and adult patients (n=22, 76% over pediatric population, n=7, 24%). 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]. The other three trials used two-stage designs like Inadmissible design, Fleming and Gehan designs. Warren KE, et al.
