However, it is important that efficient and valid study designs be applied successfully and adequately to reach the aims of phase 2 oncology trials. Inclusion of non-inferiority analysis in superiority-based clinical trials with single-arm, two-stage Simon's design. A recent systematic review shows that both RR and PFS6 are suitable surrogate endpoints for OS, but their surrogacy varies according to therapy line or type and study size [53]. Phase 2 study of Pomalidomide (CC-4047) monotherapy for children and young adults with recurrent or progressive primary brain tumors. 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. 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]. 1990;9(3):21528. 2019;85:105807. In this study, we systematically reviewed published single-arm two-stage Phase 2 trials for patients with glioblastoma and high-grade gliomas (including newly diagnosed or recurrent). Suppose both RR and PFS6 are considered primary endpoints. Trippa and colleges [55] introduced a novel composite endpoint model by combining PFS6 and OS for glioblastoma trials. (Clinical Trial). Active disease despite previous aggressive multi-drug chemotherapy, defined as one of the following: The patients must have one of the following (locally assessed) obtained within 3 weeks prior to enrollment and at least 10 calendar days after end of any prior anti-cancer treatment: Unacceptable hematological status at screening, defined as one of the following: Unacceptable liver function at screening, defined as one of the following: To learn more about this study, you or your doctor may contact the study research staff using the contact information provided by the sponsor. The median follow-up of surviving patients was 6.3 months (range, 2.2-12.5 months). Phase II open-label study of nintedanib in patients with recurrent glioblastoma multiforme. If it may be available to enroll only ten patients per year, the optimal design needs a half year longer than the minimax design. 2019;8(13):598894. When there is uncertainty among endpoints as a surrogate for OS, several primary endpoints can be employed together. Multicenter Phase II Study of Lenalidomide in Relapsed or Recurrent Adult T-Cell Leukemia/Lymphoma: ATLL-002. Brenner AJ, et al. 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 (\({r}_{1}, r\)). 2019;144(2):35968.

The most widely used endpoints were PFS6 (n=18) and ORR (n=8) in Phase 2 single-arm trials. We evaluated the efficacy and safety of valemetostat, a potent EZH1 and EZH2 inhibitor, in treating relapsed/refractory (R/R) ATL. Better understanding on the study drug information and targeted molecular information might help the understanding of why the two-stage trials had been terminated after the stage 1 and ineffective after successful completion of both stages.

Among examined 29 trials, 12 trials (41%) appropriately provided key input parameters and sample size results from two-stage design implementation. We also sought to understand how these two-stage trials have been implemented and discussed potential design issues which we hope will be helpful for investigators who work with Phase 2 clinical trials in rare and high-risk cancer studies including Neuro-Oncology. An armof a clinical trial is a group of patients receiving a specific treatment (or no treatment). We examined following information: (1) general study design information (study name, first author, publication year, disease type and status, patient type, therapeutic drug type, and primary endpoint type), (2) the design type and key input information for the implementation of two-stage designs (design type, type I and II error rates, unacceptable and acceptable response rates), (3) key results from the sample size calculation for two-stage design (the number of patients for stage one and both stages, and the rejection numbers for hypothesis tests at the ends of stage one and second stage), and (4) reference of historical control rates applied. 2021 Dec;8(12):e891-e901.

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. The sample size calculation for the two-stage designs is determined based on the historical control rate and difference between the two rates (\({p}_{0}, {p}_{1}\)). The underestimation rate of p0 was ranged from 0.1 (i.e., 10% reduction) to 0.5 (i.e., 50% reduction). Thus, the key input parameters (\(\alpha , \beta , {p}_{0}, {p}_{1}\)) and output results (\({n}_{1}, n, {r}_{1}, r\)) were investigated to assess the appropriate usage and report of the two-stage phase 2 trials. 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. 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. KH, JF, SH, and YQ report personal fees from ADC Therapeutics, during the conduct of the study.

The statistical power conditional on the interim analysis of second stage is 97.3% for the true rate of 28.9%, which is far beyond the originally pre-specified 80% of power. Phase II trial of an AKT inhibitor (perifosine) for recurrent glioblastoma. Third, when expected sample sizes from both designs are close each other, the minimax design may be more appropriate than the optimal design because the minimax design produces the smaller total patients [6]. 2021 Jun;22(6):741-742. doi: 10.1016/S1470-2045(21)00191-1.
