PS937 RANDOMIZED PHASE III HOVON-100 STUDY OF CLOFARABINE COMBINED WITH STANDARD TREATMENT IN ADULT PATIENTS WITH NEWLY DIAGNOSED ALL

TPS2072 Background: The standard treatment for patients with newly diagnosed glioblastoma comprises maximum safe surgery, radiotherapy (RT), and concomitant and up to six cycles of maintenance temozolomide (TMZ) chemotherapy (TMZ/RT→TMZ). Despite this intense therapy, the prognosis remains poor and there is an urgent need to develop new therapeutic options. Marizomib is a novel, irreversible and brain-penetrant pan-proteasome inhibitor. Following its successful assessment in phase I trials in patients with newly diagnosed as well as recurrent glioblastoma, marizomib is now being investigated in a phase III trial. Methods: EORTC 1709/CCTG CE.8 is a multicenter, randomized, controlled, open label phase III superiority trial. Eligibility criteria include histologically confirmed newly diagnosed glioblastoma and a performance status ≥70. Approximately a total of 750 patients will be enrolled and randomized 1:1. Stratification factors include institution, age, Karnofsky performance status and extent of surgery. The primary objective of this study is to compare overall survival in patients receiving marizomib in addition to standard of care (TMZ/RT→TMZ) with patients receiving standard treatment only. The testing strategy specifies the determination of this objective in both the intent-to-treat population and the subgroup of patients with tumors harboring an unmethylated MGMT promoter. Secondary endpoints include progression-free survival, safety, neurocognitive function and quality of life. The study is accompanied by a translational research program. The study will be opened at 50 EORTC sites in Europe and done as an intergroup collaboration with the Canadian Cancer Trials Group (CCTG) with 25 sites in Canada and additional sites in the US. Patient enrolment started in June 2018 and as of January 29, 2019, a total of 85 patients have been randomized. An update on the enrolment status will be provided at the ASCO conference. Clinical trial information: NCT03345095.

2004 Background: Patients with newly diagnosed glioblastoma receive postoperative standard therapy with radiotherapy (RT), and concomitant and up to six cycles of maintenance temozolomide (TMZ) chemotherapy (TMZ/RT→TMZ). Marizomib is a novel, irreversible and brain-penetrant pan-proteasome inhibitor with encouraging findings in preclinical models and early-stage clinical trials for patients with newly diagnosed and recurrent glioblastoma. Therefore, a phase 3 trial was designed to explore the activity of marizomib in addition to TMZ/RT→TMZ. ClinicalTrials.gov Identifier: NCT03345095 Methods: EORTC 1709/CCTG CE.8 is a multicenter, randomized, controlled, open label phase 3 superiority trial. Eligibility criteria included histologically confirmed newly diagnosed glioblastoma and a Karnofsky performance status (KPS) > 70. Eligible patients were stratified for institution, age, KPS as well as extent of surgery, and centrally randomized in a 1:1 ratio. The primary objective of this study is to compare overall survival (OS) in patients receiving marizomib in addition to standard treatment with patients receiving standard treatment only. Secondary endpoints include progression-free survival (PFS), safety, neurocognitive function, and quality of life. Results: The study was opened at 49 EORTC sites in Europe, 23 CCTG sites in Canada, and 8 sites in the US. Patient enrolment started in June 2018 and was close to completion at the time of a planned interim analysis in September 2020. A total of 749 patients (of the planned 750) were randomized when the IDMC recommended to discontinue enrollment. Age, KPS and extent of resection were well balanced between the 2 study arms. No difference in median OS was observed between the standard arm (15.9 months) and the marizomib arm (15.7 months; HR = 0.99). Median PFS was 6.1 vs. 6.2 months (HR = 1.02). Patients in the marizomib group had more often grade 3/4 treatment-emergent adverse events (TEAE) compared to the standard therapy group (42.6% vs. 20.5%), including ataxia, hallucinations and headache. Conclusions: The addition of marizomib to standard radiochemotherapy did not improve OS or PFS in patients with newly diagnosed glioblastoma. Final survival analyses including determination of MGMT promoter methylation status and analyses of other secondary endpoints are ongoing. Clinical trial information: NCT03345095.

BackgroundThe optimal treatment strategy for women with newly diagnosed ovarian cancer has yet to be determined. Poly(ADP-ribose) polymerase (PARP) inhibitors have demonstrated substantial improvement in progression-free survival as monotherapy maintenance treatment in the frontline setting versus active surveillance. Furthermore, preclinical and early clinical studies have shown that PARP inhibitors and immune checkpoint inhibitors have synergistic antitumor activity and may provide an additional therapeutic option for patients in this population.Primary ObjectivesIn women with newly diagnosed ovarian, fallopian tube, or peritoneal cancer, we wish to assess the efficacy of frontline maintenance treatment with the PARP inhibitor rucaparib versus placebo following response to platinum-based chemotherapy (ATHENA–MONO), and to assess the combination of rucaparib plus nivolumab (a programmed death receptor 1 (PD-1)–blocking monoclonal antibody) versus rucaparib alone (ATHENA–COMBO).Study Hypothesis(1) Maintenance therapy with rucaparib monotherapy may extend progression-free survival following standard treatment for ovarian cancer in the frontline setting. (2) The combination of nivolumab plus rucaparib may extend progression-free survival following standard treatment for ovarian cancer in the frontline setting compared with rucaparib alone.Trial DesignATHENA is an international, randomized, double-blind, phase III trial consisting of two independent comparisons (ATHENA–MONO and ATHENA–COMBO) in patients with newly diagnosed platinum-sensitive ovarian cancer. Patients are randomized 4:4:1:1 to the following: oral rucaparib+ intravenous nivolumab (arm A); oral rucaparib + intravenous placebo (arm B); oral placebo+ intravenous nivolumab (arm C); and oral placebo + intravenous placebo (arm D). The starting dose of rucaparib is 600 mg orally twice a day and nivolumab 480 mg intravenously every 4 weeks. ATHENA–MONO compares arm B with arm D to evaluate rucaparib monotherapy versus placebo, and ATHENA–COMBO evaluates arm A versus arm B to investigate the effects of rucaparib and nivolumab in combination versus rucaparib monotherapy. ATHENA–MONO and ATHENA–COMBO share a common treatment arm (arm B) but each comparison is independently powered.Major Inclusion/Exclusion CriteriaPatients ≥18 years of age with newly diagnosed advanced, high-grade epithelial ovarian, primary peritoneal, or fallopian tube cancer who have achieved a response after completion of cytoreductive surgery and initial platinum-based chemotherapy are enrolled. No other prior treatment for ovarian cancer, other than the frontline platinum regimen, is permitted.Primary EndpointThe primary endpoint is investigator-assessed progression-free survival by Response Evaluation Criteria in Solid Tumors v1.1.Sample SizeApproximately 1000 patients have been enrolled and randomized.Estimated Dates for Completing Accrual and Presenting ResultsThe trial completed accrual in 2020. While dependent on event rates, primary results of ATHENA–MONO are anticipated in early 2022 and results of ATHENA–COMBO are anticipated to mature at a later date.Trial RegistrationThis trial is registered at clinicaltrials.gov (NCT03522246).
