Wong CH, Siah KW, Lo AW. 8600 Rockville Pike How low levels for both errors are low enough to be a good design? Two types of errors (\(\alpha , \beta\)) are key information for all study designs. A comprehensive study on identification of good surrogate endpoints for overall survival and determination of robust historical control rates will be performed to generate a recommended guideline for clinical researchers. Several important topics related to the design issues will be followed to handle the design issues by increasing the precision of efficacy from targeted therapeutic trials of Phase 2 two-stage designs in brain tumor. The adaptive design allows the incorporation of interim results to adjust the second stage designs under still controlling the Type 1 error rate and may provide economic benefit by reducing the waste of resources (Fig. 2019;8(13):598894. 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]. 2020 Aug;26(8):1309. doi: 10.1038/s41591-020-0978-1.

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%]). In these cases, researchers must use endpoints like response ratethat can demonstrate clinical impact in the absence of direct comparison data.

Recent research reported that the success rate in proceeding from Phase 2 to Phase 3 was the lowest among all three rates of Phase 1 to 2, Phase 2 to 3, and Phase 3 to approval (e.g., 29.7%, 20.3%, and 35.5% for oncology and 35.2%, 27.4%, 59% for overall) [2]. Patients received valemetostat 200 mg/day until progressive disease or unacceptable toxicity. 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. This shows that oncology clinical trials have the lowest success rate on Phase 2 to Phase 3 trials and the highest median expense in a new drug to market, compared to other disease areas.
