Avelumab With Hypofractionated Radiation Therapy in Adults With Isocitrate Dehydrogenase (IDH) Mutant Glioblastoma

A Phase II, Open-label, Single Arm, Multicenter Study of Avelumab With Hypofractionated Radiation in Adult Subjects With Transformed IDH Mutant Glioblastoma

The purpose of this study is to test how safe and effective treatment with the combination of Avelumab and radiation is for IDH mutant gliomas that have transformed to glioblastoma after chemotherapy.

Study Overview

• Status: Completed
• Conditions: Glioblastoma
• Intervention / Treatment: Biological: Avelumab; Radiation: Hypofractionated radiation therapy (HFRT)

Detailed Description

The active pharmaceutical ingredient in Avelumab (MSB0010718C) is a fully human antibody of the immunoglobulin gamma-1 (IgG1) isotype that specifically targets and blocks the Programmed death-ligand 1(PD-L1) for Programmed cell death protein 1 (PD-1).

Avelumab binds PD-L1 and blocks the interaction between PD-L1 and PD-1. This removes the suppressive effects of PD-L1 on anti-tumor cluster of differentiation 8 (CD8)+ T cells, resulting in the restoration of cytotoxic T cell response.

Inclusion Criteria:

1. Male or female subjects aged ≥18 years.

Foundation Medicine's threshold for high mutation burden (HMB) in their panel NGS assays is ≥20 somatic mutations per Mb. Foundation Medicine's panel NGS assay has been validated by whole-exome and whole-genome sequencing to correlate tightly with tumor mutation burden (R2 = 0.94).96
3. Mutation in a mismatch repair gene or other genes known to be associated with hypermutator phenotypes or microsatellite instability, including but not limited to MSH2, MSH6, MLH1, POLE, PMS2, POLD as determined by validated methods.

4. Microsatellite instability as identified by polymerase chain reaction (PCR) or other validated methods.
