Webb10 maj 2024 · MGMT methylation status is a common biomarker for GBM; patients with MGMT-unmethylated GBM are known to have a worse prognosis than MGMT-methylated patients. BMS head of oncology development Fouad Namouni said: “While we are disappointed the CheckMate -498 trial did not meet its primary endpoint, GBM is a … Webb8 maj 2008 · OncoMethylome's MGMT assay is based on studies that showed that silencing the MGMT gene, via methylation, may identify brain tumors that are more likely to respond to standard chemotherapeutic agents.
WebbINTRODUCTION The CeTeG/NOA-09 trial demonstrated superior median overall survival (mOS, 48.1 months) in MGMT-methylated glioblastoma treated with lomustine/temozolomide compared to temozolomide.
