Details and patient eligibility


The purpose of this study is to evaluate the safety of multiple treatments of hAESCs treatments, while exploring the effectiveness of hAESCs treatments for PD.

Full description

The study plans to use randomized controlled trial and recruit 12 participants with Idiopathic Parkinson's disease. The trial will be divided into two groups, hAESCs treatment group and control group, each group 6 subjects. Through surgical robot technology, hAESCs will be precisely multiple transplanted into the lateral ventricles, that is two times consolidation hAESCs treatments or placebo were added to the four times basic hAESCs treatments. Therapeutic safety and effectiveness of multiple treatments of hAESCs on PD will be evaluated to further develop the optimal stem cell treatment strategy.

Inclusion criteria

  • 30-70 years old, with more than 5 years primary Parkinson's disease history, male or female;
  • The "off-age" UPDRS exercise score is between 38 and 70 points, two times before the operation, the "down period" UPDRS exercise score was stable, that is, (high value - low value) / high value ≤ 10%;

12 participants in 2 patient groups, including a placebo group

hAESCs treatment
Experimental group
A total of 6 times hAESCs transplants will be performed. 50 million (in 2ml) hAESCs will be transplanted into the ventricle of participants through the Ommaya sac (set as day 0 at the beginning of the trial). Subsequently, hAESCs ventricle transplants will be performed at 1 month ±5 days, 2 months ±5 days, 3 months ±5 days, 6 months ±5 days, and 9 months ±5 days after the first cell transplantation, with a volume of 50 million cells (in 2 ml) each time.
Biological: hAESCs treatment
Control group
Placebo Comparator group
Four times hAESCs transplants and two times placebo (cell preservation solution) injections will be performed by Ommaya sac. 50 million (in 2ml) hAESCs will be transplanted into the ventricle of participants (set as day 0 at the beginning of the trial). Subsequently, hAESCs will be transplanted into the ventricle for 3 times, respectively, at 1 month ±5 days , 2 months±5 days , and 3 months ±5 days after the first cell transplantation, with a volume of 50 million cells (in 2 ml) each time. Ventricle injection of 2 ml placebo (cell preservation solution) will be performed at 6 months ±5 days and 9 months ±5 days after the first cell transplantation.
Biological: placebo (saline)
