Safety Evaluation of Cellavita HD Administered Intravenously in Participants With Huntington's Disease

Summary

Cellavita HD is a stem-cell therapy for Huntington's Disease. This is a first-in-human, non-randomized, phase I study in which participants with Huntington's Disease will receive three intravenous injections and will be followed for 5 years to evaluate safety and tolearability of product and preliminary evidence of effectiveness.
