Eligibility Criteria

Age50 Years - 86 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Assessment of safety and exploratory treatment efficacy in subjects who were enrolled and completed phase 1/2a clinical trial of NEUROSTEM®.
  • Subjects who have been treated with either NEUROSTEM® or placebo at least 12 months ago.
  • Subjects who voluntarily decided to participate and signed the consent form after receiving explanations on the clinical trial (in case it is difficult for the participant to sign, the consent of the legal representative)

You may not qualify if:
