Painless eye drops could save sight in kids with brain tumors
NCT ID NCT05733572
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new painless nerve growth factor eye drop (CHF6467) in 36 children and young adults with optic pathway glioma, a brain tumor that often causes vision loss. The goal is to see if the drops can protect or improve vision without the pain side effects of standard nerve growth factor. Participants receive either the active eye drops or a placebo, and their vision is monitored over time.
