Clinical trial for Anaplastic Oligodendroglioma
Official title Retifanlimab With or Without Difluoromethylornithine for the Treatment of Progressive High Grade Gliomas
ClinicalTrials.gov ID: NCT07468136
What this study is testing
What is Eflornithine?
Eflornithine is an investigational medicine, being studied as a potential treatment for anaplastic oligodendroglioma.
Also referred to as Alpha-Difluoromethylornithine, DFMO.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- To learn how safe the drugs are, what side effects occur, the best dose, and whether they show any early effect in treating progressive high‑grade glioma.
- Who it's for
- Adults with a progressive high‑grade glioma (such as glioblastoma, anaplastic oligodendroglioma, or astrocytoma).
- What's involved
- You will receive an injection of retifanlimab, and may also take oral DFMO, with regular clinic visits for exams, scans, and lab tests to check safety and tumor status.
- Time commitment
- The trial runs for several months and includes multiple treatment visits and follow‑up appointments.
- Phase 2: a mid-size study of how well it works
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
