single arm phase 2 trial

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. Ott PA, Elez E, Hiret S, Kim DW, Morosky A, Saraf S, Piperdi B, Mehnert JM. Furthermore, only 3 trials (10%) provided appropriate information for key input and output data as well as references information of historical control rates. 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). J Clin Neurosci. MeSH 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.

Privacy To improve test power, we proposed a new weighted one-sample log-rank test and provided a sample size calculation formula for designing trials. Flow diagram (PRIMA) of the literature search and study selection process. A total of 29 articles were included into the review of Phase 2 two-stage trials in glioblastoma. As output results, the two-stage designs (Optimal, Minimax, and Admissible designs) produce following key outputs of the number of patients (\({n}_{1}\) and \({n}_{2}\)) for stage 1 and both stages and the rejection numbers (r and \({r}_{1}\)) for both stage 1 and both stages respectively. Department of Health & Human Services | NIH | National Cancer Institute (NCI)/International. 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. 2019;144(2):4037. J Cancer. Yoo, W., Kim, S., Garcia, M. et al. Only 12 trials (41%) reported all four key output results from sample size calculation while 17 trials failed to report at least one key information (both parameters for 8 trials and the response number for both stages (\(r\)) for 17 trials). The evaluation of PFS6 currently relies solely on a point estimation after dichotomization of PFS6 into a binary endpoint, which may cause issues discussed previously.

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]. Racine-Poon A, et al. The other three trials used two-stage designs like Inadmissible design, Fleming and Gehan designs. 133, 419427 (2017). 2011;11(5):65760. 2007;7(6):32534. 2001 May;32(2):155-62. doi: 10.1016/s0169-5002(00)00220-8.

EClinicalMedicine. Phase II study of bevacizumab and temsirolimus combination therapy for recurrent glioblastoma multiforme. 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]. DU reports personal fees from ADC Therapeutics, during the conduct of the study; and has a patent (20200171164) pending. Biostatistics. In the traditional study design of a single-arm phase II cancer clinical trial, the one-sample log-rank test has been frequently used. The primary endpoint was safety. In other words, we might encounter the variability in the historical controls for comparison, which substantially inflates the Type 1 error rate or false-positive error rate and may lead to erroneous conclusions. This phase 2 study assessed the efficacy and safety of the dual EZH1 and EZH2 inhibitor valemetostat in patients with R/R ATL. Furthermore, all trials except one trial did not explain how they chose the acceptable response rate. Single-arm studies have been traditionally used in Phase II oncology clinical trials. Optimal two-stage designs for exploratory basket trials. 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. government site. Patients received valemetostat 200 mg/day until progressive disease or unacceptable toxicity. 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%). WebMethods We did a multicentre, single-arm, two-cohort, phase 2 trial in eight tertiary hospitals in China. HHS Vulnerability Disclosure, Help Methods TOCIVID-19 is an academic multicenter, single-arm, open-label, phase 2 study. Dowlati A, Crosby L, Remick SC, Makkar V, Levitan N. Lung Cancer. Br J Cancer. The primary endpoint was overall response rate (ORR) centrally assessed by an independent efficacy assessment committee (IEAC). government site. Fifty-six of the 70 (80%) participants became desensitized to peanuts. 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.

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]. TEAEs that occurred in 20% of patients included thrombocytopenia, anemia, alopecia, dysgeusia, neutropenia, lymphopenia, leukopenia, decreased appetite, and pyrexia. Chu Y, Yuan Y. Let us assume that the result of a two-stage design indicates 18 and 23 in total patients for the minimax and optimal respectively. Results. Inclusion of non-inferiority analysis in superiority-based clinical trials with single-arm, two-stage Simon's design. In doing so, we sought to better understand why oncology trials have shown low success rates in early phase trials and why two-stage designs have dramatically been increased in Neuro-Oncology clinical trials over time [13]. 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 PMC The proportion of patients obtaining a centrally assessed complete response (CR) or partial response (PR) according to the International Neuroblastoma Response Criteria (INRC), The proportion of patients obtaining a centrally assessed CR or PR according to the INRC, The time from first centrally assessed overall response (OR) (CR or PR according to the INRC) to PD or death, the proportion of patients obtaining a centrally assessed CR according to the INRC, the time from initiation of IMP treatment until death or start of new anti-cancer treatment (prohibited as per protocol), the time from enrollment until progressive disease or death, whichever comes first, The proportion of patients alive and with no PD, Drug: Naxitamab and GM-CSF in combination with irinotecan and temozolomide. 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. Except for three clinical trials that didnt provide the methods used, almost all articles were Simons two-stage designs (n=23, 90%). Stat Med. Expert Rev Anticancer Ther. Trials involving several arms, or randomized trials, treat randomly-selected groups of patients with different therapies in order to compare their medical outcomes. Unable to load your collection due to an error, Unable to load your delegates due to an error. IEAC-assessed median DOR was not reached (NR; 95% CI, 1.87 months to NR). 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. 8600 Rockville Pike Perspect Clin Res. Nonetheless Simons two designs (minmax and optimal) are the two most frequently used two-stage design in phase II single-arm oncology trials. Bethesda, MD 20894, Web Policies Kinders R, et al. 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. 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. Bookshelf Federal government websites often end in .gov or .mil. Would you like email updates of new search results? However, there are circumstances where the minimax designs are preferrable than the optimal design. 2019 Mar;20(3):371-382. doi: 10.1016/S1470-2045(18)30812-X. Anand S, et al. 2022;169:107420. 2022 Dec 6;15:1481-1501. doi: 10.2147/OTT.S326632. Epub 2017 May 24. J Neurooncol. Lancet Oncol. Hargrave D, et al. Glioblastoma clinical trials: current landscape and opportunities for improvement. 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). Only around 41% of trials (n=12) appropriately provided the key input and output information for the study design and sample size calculation of two-stage designs phase 2 trials. One-sample multiple testing procedure for phase II clinical trials. In summary, Simons 2-stage designs, under the same type 1 error rate and power, the minimax design has a smaller total sample size than the optimal design, while the optimal design has a smaller stage 1s sample size than the minimax design. The x-axis is underestimation rate of a null hypothesis and y-axis is loss of power from the power of 80%. MeSH The followings were key words for the literature search as index terms or free-text words: phase II trials, glioblastoma, and two-stage design. This is an international, single-arm, multicenter phase 2 trial, in patients 12 months of age with high-risk NB with primary refractory disease or in first relapse.
