Spots Global Cancer Trial Database for ERC1671 to Treat Malignant Gliomas When Given in Combination With GM-CSF, Cyclophosphamide, Bevacizumab and Pembrolizumab

Study Description

Brief Summary: This is a treatment clinical trial to assess the efficacy of ERC1671 in combination with bevacizumab and pembrolizumab in patients with GBM that has progressed following treatment with radiation and temozolomide. Patients will have surgery to collect the maximum amount of GBM tissue that can be reasonably collected. This tissue will be used to manufacturer ERC1671 for the patient. The patients will receive ERC1671 in combination with GM-CSF and cyclophosphamide, in combination with bevacizumab and pembrolizumab.

Detailed Description: The treatment cycles will be 28 days long and follow the schedule below. There are 28 days (± 7 days) from surgery date to start of Cycle 1 day 1 to permit production of ERC-D vaccine: The treatment will be repeated every 28-days until progression of disease, intolerance, or a decision by the physician and/or patient to withdraw from the treatment plan. Efficacy will be evaluated as a foundation of Overall Survival reported at twelve months (OS12) Safety will be evaluated, as a secondary objective, throughout the trial by the incidence of serious adverse events (AEs), physical examination findings, vital signs and clinical laboratory test results. SAEs will be graded for severity using NCI Common Terminology Criteria for Adverse Events (CTCAE) v. 5.0. Patients will undergo brain MRI as part of standard care before starting cycle 1 and every 8 weeks thereafter (+/- 7 days) until disease progression, and whenever progression is suspected based on clinical symptoms. Tumor response will be assessed using both the Macdonald and the iRANO response criteria for high-grade gliomas, which considers radiologic imaging, neurological status, and steroid dosing. Whenever clinically appropriate, stereotactic biopsy or resection will be performed in accordance with standard of care for patients with progressive disease. To differentiate true progression from potentially toxic or therapeutic inflammatory responses presenting as radiographic or clinical changes, histologic verification of progression will be performed whenever feasible and appropriate.
