Details and patient eligibility


The purpose of this study is to investigate the effect of food on the catechol-O-Methyltransferase (COMT) activity after repeated doses of opicapone (OPC, development code BIA 9-1067) in healthy subjects and to characterize the effects of food on the pharmacokinetics (PK) and tolerability of OPC after repeated doses.

Full description

Single-centre, open-label, single-arm study in 28 healthy subjects. Subjects received a single-dose of 50 mg OPC once-daily (QD) in the evening for 12 days. On Day 1 (D1), 50 mg OPC was orally administered in the evening (reference hour for all other administrations) after a minimum of 6 hours fast. From D2 to D8 subjects were in ambulatory and received 50 mg OPC once-daily (evening administration after 2 hours fast). On D9, 50 mg OPC was orally administered in the evening after a minimum of 6 hours fast. On D10, 50 mg OPC was orally administered in the evening, thirty minutes after the start of a moderate meal (with a previous 6 hours fast). On D11 and D12 subjects received the last doses of 50 mg OPC (evening administration after 2 hours fast).
