Official title
Phase II Trial Evaluating Nivolumab In Patients With IDH-Mutant Gliomas With And Without Hypermutator Phenotype
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Gliomas are the most common malignant brain tumors. Some have certain changes (mutations) in the genes isocitrate dehydrogenase 1 (IDH1) or isocitrate dehydrogenase 2 (IDH2). If there are a high number of mutations in a tumor, it is called hypermutator phenotype (HMP). The drug nivolumab helps the immune system fight cancer. Researchers think it can be more effective in patients with IDH1 or IDH2 mutated gliomas with HMP. They will test gliomas with and without HMP. Objectives: To see if nivolumab stops tumor growth and prolongs the time that the tumor is controlled. Eligibility: Adults 18 years or older with IDH1 or IDH2 mutated gliomas Design: Participants will be screened with: Medical history Physical exam Heart, blood, and pregnancy tests Review of symptoms and activity levels Brain magnetic resonance imaging (MRI). Participants will lie in a cylinder that takes pictures in a strong magnetic field. Tumor samples Participants will get the study drug in 4-week cycles. They will get it through a small plastic tube in a vein (intravenous \[IV\]) on days 1 and 15 of cycles 1-4. For cycles 5-16, they will get it just on day 1. On days 1 and 15 of each cycle, participants will repeat some or all screening tests. After cycle 16, participants will have 3 follow-up visits over 100 days. They will answer health questions, have physical and neurological exams, and have blood tests. They may have a brain MRI. Participants whose disease did not get worse but who finished the study drug within 1 year of treatment may have imaging studies every 8 weeks for up to 1 year. Participants will be called or emailed every 6 months with questions about their health.
