Nivolumab in Patients With IDH-Mutant Gliomas With and Without Hypermutator Phenotype
NCT03718767 · View on ClinicalTrials.gov ↗
Study Summary
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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03718767
The ClinicalTrials.gov registry entry for NCT03718767 describes a study currently listed as active not recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 62 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Cancer Institute (NCI), which has 2,390 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 5 conditions, with Glioblastoma appearing as the primary indexed condition, and to 1 intervention — of which Nivolumab is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03718767 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
