The Safety and The Efficacy Evaluation of NEUROSTEM®-AD in Patients With Alzheimer's Disease

Phase 1

Completed

• Conditions: Dementia of the Alzheimer's Type
• Interventions: Biological: Human Umbilical Cord Blood Derived-Mesenchymal Stem Cells

• Registration Number: NCT01297218
• Lead Sponsor: Medipost Co Ltd.

Brief Summary

The primary purpose of this study is to evaluate the safety and the tolerability of NEUROSTEM®-AD (Human Umbilical Cord Blood Derived Mesenchymal Stem Cells) and to assess the maximum tolerated dose (MTD). This study is also to investigate the efficacy of this study drug in patients with dementia of Alzheimer's type.

Detailed Description

Most of the treatments for Alzheimer disease are chemical drug that is designed to temporarily increase acetylcholine, based on the cholinergic hypothesis. These drugs can improve the symptoms but is not able to inhibit the disease progression. New drugs from the disease have been developed but they have not been successful yet.

Mesenchymal stem cells (MSC) are capable of differentiating into various tissues. Due to the characteristics of the cells it has been widely investigated in tissue regeneration. In addition, the paracrine effect of MSC in microenvironment has been recently reported. MSC has been developed as an immunomodulation cell therapy product because it has been known that it does not cause immunological rejection in allo- and xeno-transplantation. Clinical studies showed that umbilical cord blood-derived MSC is immunologically stable and not toxic.

This study is to evaluate the safety and the tolerability of NEUROSTEM®-AD (Human Umbilical Cord Blood Derived Mesenchymal Stem Cells) and to assess the maximum tolerated dose (MTD). This study is also to investigate the efficacy of this study drug in patients with dementia of Alzheimer's type.
