A Phase 2 Randomized Open-Label Pilot Study of Granulocyte Colony Stimulating Factor (G-CSF) to Preserve Brain Structure and Function Following Standard Chemoradiation in Patients With Newly Diagnosed MGMT-Methylated Glioblastoma
Massachusetts General Hospital
Summary
This research study involves the study of granulocyte colony stimulating factor (G-CSF) in patients with MGMT-methylated glioblastoma multiforme (GBM) that are undergoing standard chemoradiation. The study aims to evaluate G-CSF's effects on brain health and cognitive function. The name of the study drugs involved in this study are: * G-CSF (also called Filgrastim) * Temozolomide (TMZ), a standard of care chemotherapy drug
Description
This is an open-label, randomized, phase II clinical study of using G-CSF in patients with newly diagnosed, MGMT-methylated, GBM treated with standard of care radiation with concurrent and adjuvant chemotherapy with temozolomide. The investigators are testing whether G-CSF can reduce the negative side effects from radiation and chemotherapy on brain health. The investigators are specifically testing the effects of G-CSF on brain structure, cognitive function, and general brain health, and the safety and tolerability of G-CSF. Participants will be randomized, stratified by age, in a 1:1 fashio…

Inclusion Criteria: * Participants must have confirmed newly diagnosed glioblastoma multiforme (GBM), World Health Organization (WHO) grade 4, IDH wildtype, either by histological or molecular criteria. * Molecular analysis needs to confirm a positive MGMT promoter methylation status using standard institutional testing methods. * Treatment needs to involve a planned 6-week course of standard of care radiation therapy with concurrent and adjuvant 6 monthly chemotherapy with temozolomide. Patients scheduled to receive an abbreviated radiation course (e.g., 3 weeks in elderly patients) are elig…
Interventions
- DrugGranulocyte Colony Stimulating Factor (G-CSF)
Subcutaneously injected study drug; standard target dose of 5-7 µg/kg/d.
- RadiationRadiation Therapy + Temozolomide
Standard of care chemoradiation is radiation therapy + Temozolomide (TMZ). Chemoradiation (chemo-RT) includes an initial 6-week cycle, followed by a 4-week break, and up to 6 additional cycles of TMZ.
