Multicenter Phase II Study of Lenalidomide in Relapsed or Recurrent Adult T-Cell Leukemia/Lymphoma: ATLL-002. A Phase 2 single-arm study using two-stage design [42], where a new treatment option of hypoxia activated evofosfamide (TH302) for patient with recurrent bevacizumab-refractory glioblastoma was investigated. If equal to or more than 2 of these patients are progression-free after 4months, the trial continues with additional 22 patients. Findings: Between March 30, 2015, and Aug 3, 2018, 79 patients were enrolled. A phase 2 study of the first imipridone ONC201, a selective DRD2 antagonist for oncology, administered every three weeks in recurrent glioblastoma. Patients pretreated with mogamulizumab had an ORR of 45.8% (4 complete and 7 partial remissions). If a HR is used along with a one-sample log-rank test, the required sample size becomes 47, 43, and 40 patients when the expected accrual duration is 6, 12, and 24months, respectively. Wouters and colleagues reported that U. S. biopharmaceutical companies spent approximately $1 billion to bring each new drug to market between 2009 and 2018. 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 (\({r}_{1}, r\)). eCollection 2020 Dec.

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).

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. 2021;13(3):28694. 2021;150:5362. 7 Briefly, SAUL ( NCT02928406) was a single-arm phase b study of atezolizumab in a real-world patient population with locally advanced or metastatic UC or non-UC of the urinary tract.
