Bookshelf and transmitted securely. 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. Findings: Between March 30, 2015, and Aug 3, 2018, 79 patients were enrolled. Englert S, Kieser M. Adaptive designs for single-arm phase II trials in oncology. These factors are recommended to be considered carefully when planning a Phase 2 single-arm study. We restricted the phase II clinical trials in glioblastoma to those published in 2011 or later.

In this phase 2 study, we demonstrated that treatment with single-agent PD-1 inhibitor was safe and associated with a 3-month OS of 60% in a heavily pre-treated https://doi.org/10.1186/s12874-022-01810-7, DOI: https://doi.org/10.1186/s12874-022-01810-7. The outcomes of simulation are depicted in Fig. 2009;45(5):7416. Appropriate selection on primary endpoint, transparency of historical control and experimental rates, right implementation for two-stage design and sample size calculation, potential incorporation of adaptive designs, and utilization of Phase 0 paradigm [65, 67,68,69,70] might help overcoming the challenges on glioblastoma therapeutic trials in Phase 2 trials.

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. sharing sensitive information, make sure youre on a federal Among 23 Simons two-stage designs, 12 trials used Simons optimal designs, 4 trials used Simons minimax designs, and 7 trials just mentions Simons two-stage designs without specific design types of the two, Optimal and Minimax. 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. 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). Ivy Brain Tumor Center, Department of Translational Neuroscience, Barrow Neurological Institute, Phoenix, AZ, 85013, USA, Karmanos Cancer Institute, Department of Oncology, School of Medicine, Wayne State University, Detroit, MI, 48201, USA, Department of Radiation Oncology, Barrow Neurological Institute, Phoenix, AZ, 85013, USA, You can also search for this author in Protracted low doses of temozolomide for the treatment of patients with recurrent glioblastoma: a phase II study. 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.

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 Muhic A, et al. 1990;9(3):21528.

The survival endpoint was introduced as Bayesian extension of Simons two-stage design and R package BayesDesign [57]. Accessibility 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. 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. Please enable it to take advantage of the complete set of features! Valemetostat demonstrated promising efficacy and tolerability in heavily pretreated patients, warranting further investigation in treating R/R ATL. 4). Cancer immunotherapy trial design with long-term survivors. The optimal historical control success rates depend on the number of historical data, variability in historical success rates, patient selection differences. Current Status of Novel Agents for the Treatment of B Cell Malignancies: What's Coming Next? Optimized image-based surrogate endpoints in targeted therapies for glioblastoma: a systematic review and meta-analysis of phase iii randomized controlled trials. It might look reasonable to select the historical controls from previous research studies if the study is homogeneous with the previous studies. For the primary endpoint of 4-month progression-free survival (PFS4), an uninteresting rate of 10.9% obtained from historical controls and an anticipated rate of 28.9% were assumed. 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]. This multicenter phase 2 trial (NCT04102150; https://clinicaltrials.gov/ct2/show/NCT04102150; DS3201-A-J201) enrolled patients with R/R aggressive ATL (acute, lymphoma, unfavorable chronic type).

But interestingly almost 60% of studies (17/29, 59%) failed to provide at least one key output results of sample size calculation such as the number of samples of first stage and both stages (\({n}_{1}, n\)) and the treatment rejection numbers of the first stage and both stages (\({r}_{1}, r\)). The most common grade 3 or higher treatment-emergent adverse events were neutropenia (37 [26%] of 145 patients), thrombocytopenia (26 [18%]), and increased gamma-glutamyltransferase (24 [17%]). Furthermore, all trials except one trial did not explain how they chose the acceptable response rate.

Epub 2020 Jun 5. In the traditional study design of a single-arm phase II cancer clinical trial, the one-sample log-rank test has been frequently used. 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.

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. Talk with your doctor and family members or friends about deciding to join a study. We study the relationship between a two-stage design with a safety endpoint and an efficacy endpoint and use simulation studies to ascertain their properties. 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]. You have reached the maximum number of saved studies (100). Stat Med. 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. 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]. WebZhao, Y., Zhang, X., Jin, C.X., et al. 2006;25(19):338295. Methods: In this open-label, single-arm, single-center, exploratory phase II study, 10 patients (20 eyes) received EG-Mirotin once a day (3 mg/1.5 mL sterile saline) for 5 days and were evaluated for ischemic index changes and safety.
