NeoCast: A new embolic treatment for chronic subdural hematoma

Official title: RADIANT: A Pivotal Clinical Study of a Next-Generation Embolic for Chronic Subdural Hematoma

Funded at Arsenal Medical, INC. · NIH-11409547 · Data updated 2026-11-12

A new, fast-acting embolic therapy called NeoCast may reduce bleeding in chronic subdural hematoma patients and lower the need for extensive brain surgery.

Who could benefit from this research

Could help

Adults with chronic subdural hematoma who are considered for middle meningeal artery embolization.

Less likely to help

Patients whose cSDH is not due to bleeding from MMA vessels or those not eligible for embolization.

What this research studies

Chronic subdural hematoma is common in older adults and is caused by fragile brain vessels. This study tests NeoCast, a solvent-free, in situ curing embolic material designed to cut off blood supply to the bleeding vessels in the skull. By potentially improving vessel penetration and reducing pain and anesthesia needs, the approach aims to improve recovery after treatment. Participants would be adults with cSDH who are candidates for embolization as part of their care.

Why it matters

Potential benefit: If successful, this therapy could reduce recurrence of cSDH and shorten hospital recovery, improving outcomes for older patients.

How similar studies have gone: Early vascular embolic approaches have shown promise, but this specific NeoCast material is novel and aims to improve penetration and safety.
