Abstract

Introduction: We conducted a phase 1 clinical trial in nine patients with mild-to-moderate Alzheimer's disease to evaluate the safety and dose-limiting toxicity of stereotactic brain injection of human umbilical cord blood-derived mesenchymal stem cells (hUCB-MSCs).

Methods: The low- (n = 3) and high-dose (n = 6) groups received a total of 3.0 × 106 cells/60 μL and 6.0 × 106 cells/60 μL, respectively, into the bilateral hippocampi and right precuneus.

Results: No patient showed serious adverse events including fever during the 24-month follow-up period. During the 12-week follow-up period, the most common acute adverse event was wound pain from the surgical procedure (n = 9), followed by headache (n = 4), dizziness (n = 3), and postoperative delirium (n = 3). There was no dose-limiting toxicity.

Discussion: Administration of hUCB-MSCs into the hippocampus and precuneus by stereotactic injection was feasible, safe, and well tolerated. Further trials are warranted to test the efficacy.

Clinical trial registration: ClinicalTrial.gov identifier NCT01297218 and NCT01696591.

Keywords: Alzheimer's disease; Hippocampus; Mesenchymal stem cell; Precuneus; Stereotactic injection.

Intraoperative navigation–guided stereotactic administration of hUCB-MSCs. hUCB-MSCs were injected into the right and left hippocampus and right precuneus at four sites (5-mm intervals) along the inserted trajectory while retracting the cannula (A). However, in six of nine patients, the fourth injection was located on the temporal horn of the lateral ventricle, probably due to substantial hippocampal atrophy. In these cases, the omitted doses were injected into the right precuneus, resulting in three injection sites in each hippocampus and six sites in the right precuneus (B). An example of stereotactic administration of hUCB-MSCs into the left hippocampus (C). Each patient received 12 injections for a total of 3.0 × 106 cells/60 μL in the low dose group or 6.0 × 106 cells/60 μL in the high dose group. Abbreviation: hUCB-MSCs, human umbilical cord blood–derived mesenchymal stem cells.
