Key inclusion & exclusion criteria

Inclusion Criteria:

- Diagnosis of idiopathic Parkinson's disease (PD) that is Levodopa-responsive.

- Must be taking a minimum of 400 mg/day of levodopa equivalents (LE) and be judged by
the investigator to have motor symptoms inadequately controlled by current therapy.

- Must have recognizable/identifiable "Off" and "On" states (motor fluctuations), and
have a minimum daily average of 2.5 hours of "Off" time (with a minimum of 2 hours of
"Off" time each day).

Exclusion Criteria:

- History of significant skin conditions or disorders (e.g., psoriasis, atopic dermatitis,
etc.) or evidence of recent sunburn, acne, scar tissue, tattoo, open wound, branding, or
colorations that in the investigator's opinion would interfere with the infusion of the
study drug or could interfere with study assessments.
