EClinicalMedicine. 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. 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. Anand S, et al. 2009;45(5):7416. Before The primary endpoint was met with a centrally reviewed ORR of 48.0% (90% CI, 30.5% to 65.9%), including 5 complete and 7 partial remissions.

WebZhao, Y., Zhang, X., Jin, C.X., et al. Tang H, et al. Optimal two-stage design of single arm Phase II clinical trials based on median event time test. Interpretation: 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. 2011;2(1):1322. 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. [56] proposed modified PFS (mPFS) for immune-oncology trials. An official website of the United States government. Please enable it to take advantage of the complete set of features! Wang Z-X, et al. 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].

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. Phase 2 trial of temozolomide and pegylated liposomal doxorubicin in the treatment of patients with glioblastoma multiforme following concurrent radiotherapy and chemotherapy. 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. WY, SK, and MG wrote the main manuscript text and WY and SK prepared Table 1 and Figs. Particularly, a recent research of the phase 2 basket trials has extended the two-stage design for multiple heterogeneous indications, which is an important tool to identify the effective drug through a generalized framework of an optimal basket design. Its interesting to see that most trials without mentioning specific design types (like Simons optimal or minimax, Gehan, Fleming, or admissible designs) failed to provide one or more than one key information for the implementation results of two-stage design sample size calculation. 2020;22(12 Suppl 2):iv196. Perspect Clin Res. Optimal two-stage designs for exploratory basket 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]. Friends of Cancer Research is a 501 (C)(3) non-profit organization.Our tax ID number is 52-1983273. 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).

Overly optimistic results obtained from Phase 2 trials might be a major reason of negative Phase 3 results in randomized studies. (Yes, No), (10) all key input and output information as well as reference of historical control rates provided (Yes, No)?, and (11) did the trial be stopped (Yes, No)? Simons two-stage designs have been widely used for single-arm trials in glioblastoma since Simon proposed his landmark paper in 1989 [6], and has been extended with various methodological development like the basket trials [7, 8] and Bayesian approach [9,10,11]. BMC Medical Research Methodology We also extracted the study results of study termination status after stage 1 and further investigation needed based on the efficacy. Pharm Stat.

Transl Cancer Res. Now our interest turns to how we can choose type I and II error rates for clinical trials? 2004;60(2):48290. Another option of two-stage designs is admissible design or spatial design, which came from an idea Can we find a good alternative design between the minimax and optimal design. Except for three clinical trials that didnt provide the methods used, almost all articles were Simons two-stage designs (n=23, 90%).

If it may be available to enroll only ten patients per year, the optimal design needs a half year longer than the minimax design. Disclaimer, National Library of Medicine 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. 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).

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 Based on this, we tested the activity and safety of alternate-day dosing of 4 mg pomalidomide on a 28/28 day schedule in a multicenter, open-label phase 2 trial Two-stage designs have become popular due to large resources for implementation and comprehensible theories with various methodologic expansion in many ways for last two decades. 2022 Feb 20;41(4):786-797. doi: 10.1002/sim.9258.

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. Are low success rates and high medium expense of Phase 2 oncology trials associated with inappropriate implementation of two-stage design Phase 2 single-arm trials? 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. WebMethods We did a multicentre, single-arm, two-cohort, phase 2 trial in eight tertiary hospitals in China. However, we should acknowledge there exist heterogeneities when we borrow the historical control information from other published studies due to different population conditions and quality of supportive care. 133, 419427 (2017).

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. 2006;25(19):338295. 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. J Clin Oncol. Loncastuximab tesirine: an effective therapy for relapsed or refractory diffuse large B-cell lymphoma. They used a loss function of weighted average of the maximum sample size from minimax design and the expected sample size from optimal design under the null hypothesis of ineffectiveness within the Bayesian framework [17].

We conducted a single-arm, phase 2 study of pembrolizumab in patients with solid tumor malignancies and LMD (NCT02886585). 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. 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). Among 29 Phase 2 single-arm trials, 23 trials (79%) used Simons two-stage designs, three trials used other two-stage designs (Gehan, Fleming and admissible design each), and 3 trials just mentioned two-stage design without specific design information.
