- Be at a stable dose of maintenance medication(s) for PD, including stable doses of CD/LD
- Subjects of childbearing potential who do not practice total abstinence must agree to use hormonal or two forms of nonhormonal contraception (dual contraception) consistently during the screening, treatment and follow-up periods of the study

- More than 2 alcoholic beverages daily or more than 14 alcoholic beverages weekly within 7 days of Day -1 or consume any alcohol within 48 hours of Day -1.
- Have motor fluctuations during the day (ie, effect of levodopa "wearing off" or having unpredictable "off" periods), or severe or intolerable levodopa-induced dyskinesia
- Have had previous exposure to opicapone, or have an allergy, hypersensitivity, or intolerance to opicapone or other COMT inhibitor.
- Have a history of a medical condition or surgical procedure that might interfere with absorption or metabolism.
