Polatuzumab vedotin plus obinutuzumab and lenalidomide in patients with relapsed or refractory follicular lymphoma: a cohort of a multicentre, single-arm, phase 1b/2 study. Lancet Oncol. Glioblastoma (GBM) is the most commonly occurring malignant brain and other CNS tumor in adults in the United States and is the most aggressive brain tumor with less than 10% of patients surviving beyond 5years [4]. Anticancer Res. 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. The primary endpoint was overall response rate (ORR) centrally assessed by an independent efficacy assessment committee (IEAC). Phase 2 single-arm trial designs typically allow Type 1 and 2 error rates up to 20% [50]. 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]. 2021;13(15):3750. Phase II study of Dovitinib in recurrent glioblastoma.

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. Neuro Oncol. End of study was approximately 8 1 weeks (57 7 days) after the first drug administration. J Clin Neurosci. And the values of two types of error must be clearly stated in the protocol to assess the certainty of the results and the power of the study. Valemetostat 200 mg orally once daily demonstrated promising efficacy and manageable toxicity in heavily pretreated patients. Oncol. J Chronic Dis. 14. 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%).

Efficacy and safety of nimotuzumab in addition to radiotherapy and temozolomide for cerebral glioblastoma: a phase II multicenter clinical trial. Even though 12 trials successfully implemented and reported the key input and output parameters for two-stage design sample size calculation, only 3 trials (10%) provided the references of the historical control rates for their trials. Such an unexpected situation cannot be appropriately handled with the current system of two-stage designs because current designs require to prespecify the design information like sample size for each stage and stopping rules in the study protocol. An increasing fraction of patients with metastatic cancer develop leptomeningeal dissemination of disease (LMD), and survival is dismal1-3. Article Temozolomide (TMZ) was mostly used for combination therapeutic drugs (n=7 with pegylated liposomal doxorubicin (PLD), O6-benzylguanine (O6B), irinotecan (IRI), decitabine (DAC), Dendritic (DEN), Nintedanib (NIN), and Atorvastatin (ATO)) while Bevacizumab (BEV) was second mostly used for combination drugs (n=3 with temsirolimus (TEM), Ponatinib (PON), and Evofosfamide (EVO)). 2021;372:n160. 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].

Bayesian hierarchical modeling of patient subpopulations: efficient designs of Phase II oncology clinical trials. To avoid this temptation, which poses a potential risk to patients, investigators should practice transparency by citing historical data sources used in the study protocol. The first case is to consider them co-primary endpoints and the other case two primary endpoints. doi: 10.1016/S2352-3026(22)00072-2.

Using a 3+3 design, 13 patients with advanced cancer were enrolled and 12 were dose-limiting toxicity (DLT) evaluable. 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. Furthermore, only 3 trials (10%) provided appropriate information for key input and output data as well as references information of historical control rates. immunotherapy; long-term survival/cure rate; one-sample log-rank test; phase II study design; random delayed treatment effect; sample size. Brief Summary: An International, Single-Arm, Multicenter Phase 2 Trial. Phase II clinical trials with time-to-event endpoints: optimal two-stage designs with one-sample log-rank test. Cancer immunotherapy trial design with long-term survivors. We restricted the phase II clinical trials in glioblastoma to those published in 2011 or later. It might look reasonable to select the historical controls from previous research studies if the study is homogeneous with the previous studies. 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. Only three trials (11%) provided key input parameters, appropriately reported output results from sample size calculation of two-stage designs, and finally provided the reference and explanation of historical control rates. 2020;20(1):126. 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.

Together they form a unique fingerprint. Unable to load your collection due to an error, Unable to load your delegates due to an error. 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%]).

We enrolled patients aged 18 years with HER2-positive breast cancer and newly Assuming a true rate of 28.9%, additional 10 patients are sufficient to achieve 80% power. Regardless that more than 75% trials mentioned all key input parameters, many studies (17/29, 59%) failed to provide at least one key output of sample size calculation results of the number of samples of both stages (\({n}_{1}, n\)) and the treatment rejection numbers of the first stage and both stages (\({r}_{1}, r\)). 2020;21(4):47182.
