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).

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.

Conditions

Glioblastoma; Gliosarcoma

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: DOUBLE

Study Groups

(ERC1671/GM-CSF/Cyclophosphamide)+bevacizumab/bevacizumab biosimilar

ERC1671 and 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 will be repeated every 28 days until progression of disease or intolerance.

(Placebo Injection/Placebo Pill) +Bevacizumab/bevacizumab biosimilar

The control group will have the same study schedule except that the patients will be receiving the Oral Control on the Cyclophosphamide treatment days and the Injectable control on the GM-CSF + ERC1671 treatment days. The control group will receive bevacizumab or approved bevacizumab biosimilar just as the active treatment group above.

The treatment will be repeated every 28 days until progression of disease or intolerance.

Eligibility Criteria

Inclusion Criteria

1. Age ≥18 years of age.

2. Histologic diagnosis of glioblastoma or gliosarcoma (WHO Grade IV).

3. KPS of ≥ 70%.

4. Life expectancy > 12 weeks.

5. First or second relapse of glioblastoma.

6. Previous treatment for glioblastoma must include surgery (biopsy, partial resection, or full surgical resection), conventional radiation therapy and temozolomide (TMZ).

7. MRI record must be obtained showing the MRI was conducted at least 4 weeks after any salvage surgery, and at least 12 weeks after radiation therapy, or at least 4 weeks after radiation for a new lesion outside the prior primary radiation field unless relapse is confirmed by tumor biopsy or new lesion outside of radiation field, or if there are two MRIs confirming progressive disease per iRANO that are 8 weeks apart

8. If prior therapy with gamma knife or other focal high-dose radiation, must have subsequent histologic documentation of local relapse, or relapse with new lesion outside the irradiated field.
