Stage 1: Marizomib + Bevacizumab in WHO Gr IV GBM; Stage 2: Marizomib Alone; Stage 3: Combination of Marizomib and Bevacizumab
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.
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 a Phase 2 Studies of Single Agent Marizomib and Combination Marizomib and Bevacizumab and Phase 1 Dose-Escalation Study of Enterally-administered Marizomib With Bevacizumab
One of the few treatment options currently FDA approved for recurrent WHO Grade IV malignant glioma is BEV. Additional treatment options are needed for these subjects. Published literature indicates that targeting the proteasome in glioma cells has shown significant anti-tumor activity.
MRZ is a novel, second generation proteasome inhibitor that prevents the breakdown of proteins involved in signal transduction which blocks growth and survival of cancer cells. In-vitro studies of multiple glioma cell lines were highly sensitive to MRZ. MRZ had relatively little effect on neural stem/progenitor cells suggesting minimal neurotoxicity while significantly affecting both malignant glioma stem cells and glioma cell lines.
Parts 1 and 2 of this trial have been completed with the Recommended Part 3 (Phase 2) Dose established at 0.8 mg/m2. Part 3 of this trial is enrolling at the MRZ RP2D determined in Phase 1 to assess the combination of MRZ and BEV activity and safety.
Parts 1, 2, and 3 of this trial have been completed with the Recommended Dose established at 0.8 mg/m2. Part 4 of this trial is enrolling.

- All subjects must have histologic evidence of G4 MG (including glioblastoma and gliosarcoma) and radiographic evidence of recurrence or disease progression (defined as either a greater than 25% increase in the largest bidimensional product of enhancement, a new enhancing lesion, or significant increase in T2 FLAIR).
- Subjects must have previously completed standard radiation therapy and been exposed to temozolomide. Patients must be in first or second relapse.

- No investigational agent within 4 weeks prior to first dose of study drug.
- At least 4 weeks from surgical resection and 12 weeks from end of radiotherapy prior to enrollment in this study, unless relapse is confirmed by tumor biopsy or new lesion outside of radiation field, or if there are two MRIs confirming progressive disease that are 8 weeks apart.
- Subjects with a history of seizures must be on a stable dose of anti-epileptic drugs (AEDs) and without seizures for 14 days prior to enrollment in patients enrolled prior to Amendment 2. Subjects enrolled after Amendment 2 is approved with a history of seizures must be on a stable dose of anti-epileptic drugs (AEDs) for 7 days prior to enrollment.
- . All AEs resulting from prior chemotherapy, surgery, or radiotherapy, must have resolved to at least NCI-CTCAE (v. 4.03) Grade 1 (except for laboratory parameters outlined below).
- . Laboratory results within 7 days prior to MRZ administration (transfusions and/or growth factor support may not be used to meet this criteria):

- Hemoglobin at least 9 g/dL
- Absolute neutrophil count (ANC) at least 1,500/mm3
- Serum bilirubin at least 1.5 × upper limit of normal (ULN) or at least 3 × ULN if Gilbert's disease is documented

You CAN'T join if...
- Co-medication that may interfere with study results, eg, immuno-suppressive agents other than corticosteroids. (Steroid therapy for control of cerebral edema is allowed at the discretion of the Investigator. Subjects should be on a stable dose of steroids for at least 1 week prior to first dose of MRZ. Co-medications must not be taken for 2 hours prior to and up to 2 hours after enteral administration of MRZ (Part 4 Phase 1).
- Evidence of CNS hemorrhage on baseline MRI or CT scan (except for post-surgical, asymptomatic Grade 1 hemorrhage that has been stable for at least 3 months for subjects enrolled prior to Amendment 2 and for at least 4 weeks in subjects enrolled after Amendment 2 is approved).
