NCT ID NCT06462222

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tests a new treatment for leptomeningeal metastasis, a condition where cancer spreads to the lining of the brain and spinal cord. The treatment combines an immune checkpoint inhibitor (a drug that helps the immune system fight cancer) with pemetrexed (a chemotherapy drug), both injected directly into the spinal fluid. The study involves 45 adults with solid tumors and aims to find the safest dose and check for side effects.
