Phase 3 Study Comparing Selumetinib With Carboplatin and Vincristine in Children and Young Adults With Newly Diagnosed or Untreated Low-Grade Glioma Without BRAFV600E Mutation or Neurofibromatosis Type 1

What this Trial Is About

Researchers are comparing two treatments for children and young adults aged 2 to 21 with newly diagnosed or untreated low-grade glioma LGG that does not have a BRAFV600E mutation or neurofibromatosis type 1 NF1. The study aims to find out if selumetinib, a drug that blocks enzymes needed for tumor cell growth, works as well as the standard chemotherapy treatment with carboplatin and vincristine CV. It also evaluates which treatment better improves quality of life and patient outcomes. Participants are randomly assigned to one of two groups. One group receives vincristine intravenously on specific days along with carboplatin intravenously on scheduled days, followed by maintenance cycles every 42 days for up to 8 cycles. The other group takes selumetinib orally twice daily in 28-day cycles for up to 27 cycles. Throughout the trial, patients undergo blood collection, MRI scans, and in the selumetinib group, echocardiography at baseline. Treatments continue unless there is disease progression or unacceptable side effects. During participation, patients have various assessments including tumor imaging, blood tests, and evaluations of vision and motor function. Quality of life and cognitive, social, emotional, and behavioral functions are also measured. After treatment, patients are followed every 3 months for the first year, every 6 months for years 2 and 3, and then annually up to 10 years. The main outcome measured is event-free survival over this period.
