ERC1671/GM-CSF/Cyclophosphamide for the Treatment of Glioblastoma Multiforme
Study Details
Study Description
Brief Summary
This phase II clinical trial studies how well ERC1671 plus Granulocyte-macrophage colony-stimulating factor (GM-CSF) plus Cyclophosphamide with Bevacizumab works compared to Placebo Injection plus Placebo Pill with Bevacizumab in treating patients with recurrent/progressive, bevacizumab naïve glioblastoma multiforme and gliosarcoma (World Health Organization (WHO) grade IV malignant gliomas, GBM).

Phase 2 |
Detailed Description
This is a blinded Phase II study of ERC1671 in combination with bevacizumab in patients with relapsed, bevacizumab naive glioblastoma. The patients who will be randomized (in a 1:1 ratio) to receive either ERC 1671 in combination with GM-CSF and cyclophosphamide or a placebo control, in combination with bevacizumab. The study will be double blinded.
ERC1671/GM-CSF will be intradermally administered, while cyclophosphamide is orally administered. GM-CSF dose is 500mcg fixed dose and cyclophosphamide dose is 50 mg/day. Bevacizumab or approved bevacizumab biosimilars are administered as standard of care at 10 mg/kg every 2 weeks.
The treatment cycles will be 28 days long.

Outcome Measures
Primary Outcome Measures
- Overall Survival at 12 months of patients with recurrent, bevacizumab naïve glioblastoma treated with ERC1671 in combination with GM-CSF and cyclophosphamide plus bevacizumab as compared with patients receiving bevacizumab plus placebo controls. [12 months]
To evaluate overall survival in patients with with recurrent, bevacizumab naïve glioblastoma treated with ERC1671 in combination with GM-CSF and cyclophosphamide plus bevacizumab as compared with patients receiving bevacizumab plus placebo controls.
Secondary Outcome Measures
- Rate of Progression-Free Survival [12 months]
Progression-free survival will be defined as the time from Day 1 to the date of progression or death due to any cause.
- Immune Response [12 months]
The patient's immune response evaluation will include cytotoxic T lymphocytes (CTL) (CD3+/cluster of differentiation (CD)8+) and Treg (CD3+/CD4+/cluster of differentiation 25+ (CD25+)/CD127low) populations where CD refers to cluster of differentiation. Cytokine analyses should initially be limited to IFN-ɣ, TNF and IL-6. Further immune studies should include transforming growth factor (TGF)-B2, IL-12, IL-10.
- Percentage of Grade 3-5 Adverse Events [12 months]
Toxicity and adverse events are based on the CTCAE (NCI Common Terminology Criteria for Adverse Events) Version 4.0. Safety will also be assessed by clinical laboratory tests, physical examinations, vital sign measurements and the incidence and severity of adverse events (AEs).
- Rate of Radiographic Response as assessed using MacDonald Criteria or IRANO [12 month]
Patients will be followed both clinically and radiographically every 6 weeks for evidence of tumor progression. Tumor response will be assessed using the MacDonald Criteria or iRANO, Immunotherapy Response Assessment in Neuro-Oncology. iRANO/MacDonald CRITERIA: Complete response (CR): Disappearance of all enhancing tumor on contrast enhanced MRI scan. Partial response (PR): Greater than or equal to a 50% reduction in the size (sum of products of the largest diameter, SPD) for all enhancing lesions. Stable Disease (SD): SPD <50% decrease to <25% increase, does not qualify for CR, PR, or progression. Progressive Disease (PD): Greater than or equal to a 25% increase in SPD. Unable to Assess (UA): Some target lesions cannot be evaluated because of technical factors.
