Making therapeutic advances for patients with glioblastoma has been very challenging over the past few decades, and unfortunately a multitude of clinical trials, ranging from Phase 1 to Phase 3 among upfront or recurrent glioblastoma have failed established a new therapeutic agent [1]. Wang et al. Pharm Stat. 2022 Sep;11(9):3349-3356. doi: 10.21037/tcr-22-1211. PMC An interesting novel surrogate endpoint is the post-progress survival (PPS), defined as the duration from the start of a second-line treatment to death.

Patients will receive naxitamab + GM-CSF + irinotecan/temozolomide. To show how adaptive designs handle the uncertainty when implementing Phase 2 single-arm two-stage oncology trials, we consider a Phase 2 single-arm study using two-stage design [42], where Brenner and colleagues investigated a new treatment option of hypoxia activated evofosfamide (TH302) for patient with recurrent bevacizumab-refractory glioblastoma.

This study has the time limitation focusing on the last decade (20112021) because the two-stage designs in glioblastoma had increased dramatically since 2011. Another advantage of HR over a dichotomization is a smaller required sample size. 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. The unacceptable historical control rate should be a maximum rate while the acceptable expected treatment rate should be a minimum rate in order not to be overly optimistic for the Phase 2 clinical trials.

Phase 0 clinical trials: recommendations from the task force on methodology for the development of innovative cancer therapies. Br J Cancer. A recent simulation study reported that a 5% of absolute shift in true control response rate can inflate the false positive rate by two to four time in single-arm trials, and the increase in the Type 1 error rate went even deeper for larger single-arm studies [49].

Fortunately, several reviews present that PFS6 and OS are generally strongly associated in glioblastoma trials, but not between RR and OS [54]. Multistage designs for phase II clinical trials: statistical issues in cancer research. Phase 2 trial of hypoxia activated evofosfamide (TH302) for treatment of recurrent bevacizumab-refractory glioblastoma.

Patients received valemetostat 200 mg/day until progressive disease or unacceptable toxicity. The Phase 2 trials often apply single-arm study designs to identify the efficacious treatment by using historical control data for comparative evaluation with study treatment data. 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].

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. Eur J Cancer. 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]. Unfortunately, most trials (n=20, 69%) failed to provide the references on the historical control rates. 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.
