Brief Summary:
This study is an extension to the HP-CD-CL-2002 clinical study. It evaluates the long-term safety and tolerability of CDNF in patients with Parkinson's disease when dosed directly into the brain using an implanted investigational drug delivery system (DDS). Long-term safety of the DDS is also being evaluated. All patients will receive monthly infusions of either mid- or high-dose of CDNF for a period of 6 months.
