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. OPTIM-ARTSAn adaptive phase II open platform trial design with application to a metastatic melanoma study. Together they form a unique fingerprint. Except for three clinical trials that didnt provide the methods used, almost all articles were Simons two-stage designs (n=23, 90%). 2012;110(1):1118.

The study met the primary endpoint, as 12 of 20 (OS3, 0.60; 90% confidence interval, 0.39-0.78) patients were alive at 3 months after enrollment. 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. Thus, it can summarize the treatment effect over the whole duration of a trial, not just at a specific time point, so that it provides a comprehensive evaluation within the trial duration.

Your comment will be reviewed and published at the journal's discretion. Glioblastoma clinical trials: current landscape and opportunities for improvement. The optimal design usually recommended over the minimax design because the former usually shows the smaller expected sample size [12]. Evaluating efficacy and safety of loncastuximab tesirine injection for the treatment of adult patients with relapsed or refractory large B-cell lymphoma. Table 1 shows the summary of the included studies for Phase 2 single-arm two-stage clinical trials in glioblastoma. The median follow-up of surviving patients was 6.3 months (range, 2.2-12.5 months). Most studies (n=27, 93%) provided the number of patients in stage 1 and both stages, so many trials (n=17) failed to report one or more from both response numbers of stage 1 and both stages which are key information to determine the study continuation toward the second stage (\({r}_{1}\)) at the end of first stage and hypothesis testing of efficacy (\(r\)) at the end of second stage.

Contemp Clin Trials. The .gov means its official. Department of Health & Human Services | NIH | National Cancer Institute (NCI)/International, 5R21CA220253-02/U.S. 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]. Accessibility Finally, we can calculate the expected sample sizes of \({n}_{1}\) or \(n\) with a true response rate of the experimental therapy since the sample size of \({n}_{1}\) and \(n\) are random variables [6, 12, 17]. Du XJ, et al. Unlike a survival rate at a specific time point, a HR is not a point estimate and uses all the information in the entire survival curve. Leveraging Molecular and Immune-Based Therapies in Leptomeningeal Metastases. doi: 10.1371/journal.pone.0246448. 2019;85:105807. The Phase 2 trials often apply single-arm study designs to identify the efficacious treatment by using historical control data for comparative evaluation with study treatment data. 2012;4(4):799801. For instance, in Case 3, the 10% and 50% reductions of p0 are 0.45 (=0.50.9) and 0.25 (=0.50.5). Comput Stat Data Anal. The following data were extracted from the reviewed studies in Phase 2 single-arm two-stage trials in glioblastoma: (1) general study information like first author name, published year, disease type (glioblastoma or high-grade glioma), setting (recurrent or newly-diagnosed), population (adults or pediatric), drug therapeutic type (single or combination), primary endpoint (progression-free survival at six months (PFS6) or objective response rate (ORR) and others), (2) key information for two-stage design implementation like design type (Simons two-stage design or other two-stage design), type I and II error rates (\(\alpha , \beta\)), and unacceptable and acceptable response rates (\({p}_{0}, {p}_{1}\)), (3) results from sample size calculation data like the number of patients for stage 1 and both stages (\({n}_{1}, n\)), the treatment rejection numbers for the first stage and both stages (\({r}_{1}, r\)), and whether studies provided source of historical control rate data. 2022 May;78(5):707-719. doi: 10.1007/s00228-021-03253-3. 2021;11:660892. Multistage designs for phase II clinical trials: statistical issues in cancer research. Spatial two-stage designs for phase ii clinical trials. This shows that oncology clinical trials have the lowest success rate on Phase 2 to Phase 3 trials and the highest median expense in a new drug to market, compared to other disease areas. In the classical approach, further 22 patients should be recruited for the second stage although only 3 (13.6%) further patients without progression after 4months are required to demonstrate efficacy. Chu Y, Yuan Y. Accessibility We conducted the prospective, open-label, single-arm, phase 2 TUXEDO-1 trial. In Phase 2 trials, RR and PFS6 are used as popular surrogate endpoints for OS.

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 Jung SH, et al. 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. J Neurooncol. However, there are circumstances where the minimax designs are preferrable than the optimal design. Epub 2022 Apr 1. J Neurooncol.

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. Lastly, this study focuses on right implementation for the study design and sample size calculation. Eur J Cancer. Careers. Mateos et al. To illustrate the effect of underestimated historical control on the study power, we carried out a simulation study as follows. We systematically reviewed published single-arm two-stage Phase 2 trials for patients with glioblastoma and high-grade gliomas (including newly diagnosed or recurrent). J Clin Oncol. Ott PA, Elez E, Hiret S, Kim DW, Morosky A, Saraf S, Piperdi B, Mehnert JM. Unable to load your collection due to an error, Unable to load your delegates due to an error. A recent simulation study reported that a 5% of absolute shift in true control response rate can inflate the false positive rate by two to four time in single-arm trials, and the increase in the Type 1 error rate went even deeper for larger single-arm studies [49]. Hyun JW, Kim Y, Kim KH, Kim SH, Park EY, Youn JH, Yoo H, Gwak HS, Kim HJ. Sort by Weight Alphabetically Medicine and Dentistry Patient 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). 1. Using four key input parameters of two types of error (\(\alpha , \beta\)) and two hypothesis rates of unacceptable maximum response rate of historical control (\({p}_{0}\)) and acceptable minimum response rate of study expectation (\({p}_{1}\)), we can implement the sample size calculation of the two-stage designs.

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]. Intrathecal administration of trastuzumab for the treatment of meningeal carcinomatosis in HER2-positive metastatic breast cancer: a systematic review and pooled analysis. A total of 17 drugs were used as single therapeutic treatment with Sunitinib (SNT) and Nintedanib (NIN) from two studies each, and Temozolomide (TMZ), Bendamustine (BEN), Temsirolimus (TMS), Gimatecan (GMT), Bosutinib (BOS), Dasatinib (DAS), Tivozanib (TIV), Imipridone (IMI), Ortatzxel (ORT), Dovitinib (DOV), Perifosine (PRF), Thrombopoietin receptor (THR), and Pomalidomide (POM) from single study each. 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%). mPFS does not include the events of disease progression but include the events of death within 3months after randomization.

Due to economical and ethical reasons, the two-stage designs have been widely used for Phase 2 single-arm trials in oncology because the designs allow us to stop the trial early if the proposed treatment is likely to be ineffective. Naxitamab and GM-CSF will be given for at least 8 cycles. Twenty-five patients (median age, 69.0) with a median of 3 prior lines of therapy were enrolled; 24 had prior mogamulizumab treatment.
