Improvement of Functional Outcome for Patients With Newly Diagnosed Grade 2 or 3 Glioma With Co-deletion of 1p19q - IMPROVE CODEL the NOA-18 Trial

What this Trial Is About

Researchers are investigating treatments for oligodendrogliomas, a type of brain tumor classified by specific genetic markers including mutations in isocitrate dehydrogenase IDH and co-deletion of chromosomes 1p19q. This trial focuses on adults with newly diagnosed grade 2 or 3 gliomas, aiming to improve survival without loss of brain function, cognition, or quality of life. The study compares two treatment approaches to determine the best timing and combination of chemotherapy and radiotherapy. Participants are randomly assigned to receive either standard chemoradiation with procarbazine, CCNU lomustine, and vincristine PCV combined with radiotherapy, or an experimental approach starting with chemotherapy using lomustine and temozolomide CETEG followed by radiotherapy and PCV at tumor progression. Radiotherapy is delivered over about 5 to 6 weeks, with doses adjusted for tumor grade. Chemotherapy cycles last 6 weeks and include specified doses of oral and intravenous drugs. During the study, participants undergo regular magnetic resonance imaging MRI scans every three months, neurological assessments, quality of life questionnaires, and cognitive testing annually. The main outcome measured is qualified overall survival, which tracks survival without significant cognitive or functional decline. The study lasts up to 10 years, with ongoing monitoring of tumor progression, treatment response, and patient wellbeing. Safety and side effects are carefully assessed throughout the trial.
