Phase 1, Multicenter, Open-label, Dose-escalation, Combination Study of Marizomib and Bevacizumab in Bevacizumab-Naïve Subjects With WHO Grade IV Malignant Glioma Followed by Phase 2 Studies of Single Agent Marizomib and Combination Marizomib and Bevacizumab, and Phase 1 Dose-Escalation Study of Enterally-administered Marizomib With Bevacizumab
In Brief
A Phase 2 clinical trial evaluating MRZ and BEV for Malignant Glioma and Glioblastoma. Completed, enrolled 121 participants across 5 sites in 2 countries.
Detailed Summary
This is a Phase 1/2 clinical trial to evaluate a new combination of drugs, marizomib (MRZ) and bevacizumab (BEV; Avastin®), for the treatment of WHO Grade IV malignant glioma. The study population includes subjects who are in first or second relapse and who have not previously received any bevacizumab or other anti-angiogenic agent or proteasome inhibitor for treatment of malignant glioma. Part 1 Phase 1 evaluates the combination of MRZ and BEV, while Part 2 Phase 2 evaluates single-agent MRZ. Part 3 (Phase 2) includes a combination MRZ using intra-patient dose escalation, and BEV at a fixed dose. Part 4 Phase 1 evaluates MRZ through enteral administration, and BEV at a fixed dose. Part 5 Phase 1 evaluates the repeat-dose pharmacokinetics of MRZ administered IV with ECG.

Interventions
MRZ dosing in Phase 1 to range from 0.55 to 0.8 mg/m2. Dose Escalation: MRZ dose-escalation will occur using a standard 3+3 study design. The RP2D of MRZ (0.8.mg/m2) will be used in a two stage design, with fifteen response-evaluable patients entered in the first stage. If 1 or more responses are observed at the MRZ RP2D, then the second stage will be implemented with an additional 15 response-evaluable patients treated.
BEV 10 mg/kg IV infusion administered for all cohorts in Phase 1 only.
