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.
Detailed Description

A patient's participation in the study will last for six months and will include nine visits:

Screening (1 visit, same as HP-CD-CL-2002 End-of-Study visit) Dosing visits: CDNF (6 visits) DAT-PET (1 visit) End-of-study visit (1 visit)

Study examinations and assessments

  • Physical examination: pulse rate, blood pressure, temperature, body weight and height, body mass index (BMI), neurological exam
  • ECG (electrocardiography) and blood and urine tests
  • Pregnancy tests for women of childbearing age
  • Completion of a patient diary to record mobility and time asleep
  • Parkinson's Kinetigraph (PKGTM) Data Logger: a watch-type movement recording device
  • Questionnaires, rating scales and forms: quality of life, mood, memory, impulse control, mental health
  • Assessment of the port and the skin around the port
  • Cerebrospinal fluid sampling by lumbar puncture
  • Magnetic resonance imaging (MRI)
  • Positron emission tomography scans (PET)
