Brief Summary

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

OBJECTIVES:

I. Determine the effectiveness of fetal nigral transplantation in patients with Parkinson's disease.

Detailed Description

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

PROTOCOL OUTLINE: This is a placebo controlled, randomized, double blind study. Patients are randomly assigned to 1 of 3 treatment groups. All patients receive 2 separate operations in which the substantia nigra from either 4 fetuses (Group A) or 1 fetus (Group C) is implanted into the striatum of each side.

Group B patients receive 2 separate placebo operations without fetal transplantation.

The second surgical procedure begins approximately 1 week after the first operation.

After 2 years, treatments are compared. If transplant is shown to benefit Parkinson's disease, then patients who received placebo operation will be offered transplant surgery in the final year of the study.
