This study is a follow up to the HP-CD-CL-2002 clinical study. It evaluates the long-term safety in patients with Parkinson's disease after implantation of an investigational drug delivery system (DDS) with or without infusions of CDNF. All patients will have at least the port explanted.
A patients participation in the study will last for up to 4 years and will include up to nine visits:
Study examinations and assessments:
