Cont. of a Study to Evaluate Implanting Peripheral Nerve Grafts Into Subjects With Parkinson's Disease (PD) During DBS

NCT02369003 | Active Not Recruiting Phase 1

• 1 other identifier: 14-0729-F6A
• Study Type: interventional
• Target: 70
• Locations: 1 country
• Sites: 1

Brief Summary

This pilot study is designed to follow up on a previous, preliminary study and test the long-term safety and feasibility of the implantation of autologous peripheral nerve grafts into the substantia nigra, basal forebrain, putamen, and/or STN of participants with PD undergoing deep brain stimulation (DBS) surgery. Peripheral nerve tissue contains Schwann cells which produce growth factors that have been demonstrated to support the survival and function of neurons. Participants will serve as their own donor for the tissue, which will be implanted at the time they undergo DBS surgery.

Conditions

Parkinson's Disease

Keywords

Deep Brain Stimulation; Schwann Cells

Outcome Measures

Primary Outcomes (1)

• Number of Participants with Adverse Events as a Measure of Safety and Tolerability

  Safety and Tolerability of Nerve Graft Implantation. Adverse events will be collected in order to measure the safety and tolerability of the grafting procedure. Adverse events will be documented and compared to the known and reported adverse events of DBS of Subthalamic Nucleus (STN) or internal globus pallidus (GPi).

  15 years

Secondary Outcomes (1)

• DaTscan assessment

  12 or 24 months

Study Arms (1)

Peripheral Nerve Graft

EXPERIMENTAL

The intervention includes the surgical implantation of autologous peripheral nerve graft into the substantia nigra, basal forebrain, putamen, and/or STN of participants with Parkinson's Disease that are undergoing Deep Brain Stimulation (DBS).

Procedure: Autologous Peripheral Nerve Graft

Interventions

Autologous Peripheral Nerve Graft PROCEDURE

Implantation of Autologous Peripheral Nerve Graft into the substantia nigra, basal forebrain, putamen, and/or STN of participants with PD undergoing deep brain stimulation (DBS) surgery.
