NCT02780895

Brief Summary

Implantation of Celavie human stem cells (OK99) is intended to address the underlying pathology of the disease by replacing damaged/destroyed cells of the brain, and/or stimulating the patient's brain to repair itself.

EXPERIMENTAL

stereotactic brain surgery of human stem cells (OK99)

Drug: Human Stem Cells

Interventions

MRI-guided stereotactic intraputaminal cell implantation into PD patients was performed. For target locations, measurements were made using CT-scan images fused with previous MR images. Bilateral parasagittal incisions and corresponding 14 mm burr holes were made in preparation for cell suspension injections. To ensure complete cell suspension delivery, injections were carried out slowly for 2 min with reciprocal withdrawal of the delivery needle to avoid both damage to stem cells and brain tissue, as well as to avert reflux or bubble formation. After surgery, patients were kept in a conventional post-operative care unit for 1 h. The day following surgery, MR images were obtained to confirm correct placement of cell suspensions. All patients were discharged 24 h after surgery.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
