BMJ. A common practice in sample size calculation is Searches were conducted using the electronic database of PubMed, Google Scholar and ClinicalTrials.gov for potentially eligible publications from inception by two independent researchers up to May 26, 2022. 2012;106(3):6439. 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 enrolled patients aged 18 years with HER2-positive breast cancer and newly Among appropriately implemented 12 trials, discouragingly only 3 trials (10%) explained the reference information of historical control rates. Neurol. 2022 Dec;17(6):524-532. doi: 10.1159/000526431. BMC Med Res Methodol 22, 327 (2022). 133, 419427 (2017). Odronextamab, a human CD20CD3 bispecific antibody in patients with CD20-positive B-cell malignancies (ELM-1): results from the relapsed or refractory non-Hodgkin lymphoma cohort in a single-arm, multicentre, phase 1 trial. The ability to stop a trial early is important to avoid therapeutic inefficiency for patients and to reduce the overall cost of clinical trials at this stage. Phase II study of bevacizumab and temsirolimus combination therapy for recurrent glioblastoma multiforme. Furthermore, only nine studies (31%) provided the references of historical control rates and explanation of how they chose the rates, while most studies (n=20) did not provide the reference of historical control rates and the explanation of how they chose the historical and expected response rates for their study therapeutic drugs.

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. 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. Bendamustine treatment of Chinese patients with relapsed indolent non-Hodgkin lymphoma: a multicenter, open-label, single-arm, phase 3 study. 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.

In safety studies, a main concern is that there may be too many patients who experience an adverse event. To illustrate the effect of underestimated historical control on the study power, we carried out a simulation study as follows.

Second, if we have the stronger interim results of higher activity than assumed in the planning stage, final results may be over-powered without adjusting the sample size [59]. We systematically reviewed published single-arm two-stage Phase 2 trials for patients with glioblastoma and high-grade gliomas (including newly diagnosed or recurrent). 2022 Sep;11(9):3349-3356. doi: 10.21037/tcr-22-1211.

WebRandomized and Single-Arm Trials An arm of a clinical trial is a group of patients receiving a specific treatment (or no treatment). Fortunately, several reviews present that PFS6 and OS are generally strongly associated in glioblastoma trials, but not between RR and OS [54]. The Follow-Up period ends 2 years after End of Treatment. EG-Mirotin safety and efficacy were investigated in patients with type 1 or type 2 diabetes mellitus and moderate to severe NPDR.

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. The underestimation rate of p0 was ranged from 0.1 (i.e., 10% reduction) to 0.5 (i.e., 50% reduction).
