New gene therapy hopes to fix fatal brain diseases
NCT ID NCT07445490
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new gene therapy for GM2 gangliosidosis, which includes Tay-Sachs and Sandhoff diseases. Researchers will take blood cells from 6 patients, fix the genetic defect in the lab, and then see if these cells can help brain cells work better. The goal is to show the treatment is safe and effective enough to move forward.
