Fetal nigral transplantation in Parkinson Disease - Clinical Trials Registry

Study Overview

Status

Completed

Conditions

Parkinson Disease

Intervention / Treatment

Procedure: fetal nigral transplantation

Detailed Description

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.
