Primary Mitochondrial Diseases Clinical Trial
Official title:
A First in Human Phase I, Open Label Dose-escalation Study to Evaluate the Safety of Infusion of MNV-BM-PLC (Autologous CD34+ Cells Enriched With Placenta Derived Allogeneic Mitochondria) in Patients With Primary Mitochondrial Diseases Associated With Mitochondrial DNA Mutation or Deletion
The study objectives are to evaluate the safety of a single intravenous (IV) infusion of autologous CD34+ cells enriched with placenta-derived allogeneic mitochondria in participant with primary mitochondrial disease associated with mitochondrial DNA mutations or deletions. 6 participants aged from 4 to 18 years old on the day of screening visit with primary mitochondrial disease associated with mitochondrial DNA mutations or deletions will be enrolled.
