Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the safety and efficacy of allogenic pluripotent stem cells isolated from adipose tissue (PASCs) in patients with Parkinson's Disease.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pluripotent Adipose-Derived Stem Cells (PASCs) will be delivered intravenously at a dosage of 25 million PASCs/patient to Parkinson's Disease patients for three infusions each spaced 3 months apart (0, 3, and 6 months). Safety and efficacy of PASC treatment will be monitored over 0, 1, 3, 6, and 12 months.
