Brief summary: To investigate the effect of three single oral doses of BIA 9-1067 (25 mg, 50 mg and 100 mg) on the levodopa pharmacokinetics when administered in combination with a single-dose of immediate-release levodopa/benserazide 100/25 mg (Prolopa® 100-25)


Eligibility criteria: Inclusion Criteria:

1. Availability for the entire study period and willingness to adhere to the protocol requirements as evidenced by the informed consent form (ICF) duly read, signed and dated by the volunteer prior to participation in the study.

5. Volunteers who are non- or ex-smokers. An ex-smoker is defined as someone who completely stopped smoking for at least 12 months before day 1 of this study.
6. Volunteers who are healthy as determined by pre-study (at screening) medical history, physical examination, vital signs, complete neurological examination and 12-lead ECG.
7. Volunteers who have clinical laboratory test results judged clinically acceptable (within the laboratory's stated normal range; if not within this range, they must be without any clinical significance) at screening and admission to first treatment period.
8. Volunteers who have negative tests for hepatitis B surface antigen (HBsAg), anti-hepatitis C antibodies (HCV Ab), and Human immunodeficiency viruses -1 and -2 antibodies (HIV-1 and HIV-2 Ab) at screening.
9. Volunteers who have negative screen of ethyl alcohol and drugs of abuse at screening.
10. Due to unknown risks and potential harm to the unborn fetus, sexually active men must agree to use a medically acceptable form of contraception throughout the study.

Exclusion Criteria:

1. Volunteers who do not conform to the above inclusion criteria, or in case of
2. Volunteers who have a clinically relevant surgical history.
3. Volunteers who have a clinically relevant family history.
4. Volunteers who have a history of relevant atopy.

6. Volunteers who have acute gastrointestinal symptoms at the time of screening or first admission (e.g., nausea, vomiting, diarrhoea, heartburn).
7. Volunteers who are vegetarians, vegans or have medical dietary restrictions.
8. Volunteers who cannot communicate reliably with the investigator.
9. Volunteers who are unlikely to co-operate with the requirements of the study.
10. Significant history of hypersensitivity to BIA 9-1067, tolcapone, entacapone, levodopa, benserazide or any related products (including excipients of the formulations) as well as severe hypersensitivity reactions (like angioedema) to any drugs.
11. Presence of significant gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs or known to potentiate or predispose to undesired effects.
12. History of significant gastrointestinal, liver or kidney disease that may affect drug bioavailability.
13. Presence or history of significant cardiovascular, pulmonary, hematologic, neurologic, psychiatric, lymphatic, musculoskeletal, genitourinary, endocrine, immunologic, dermatologic or connective tissue disease.
14. Suicidal tendency, history of or disposition to seizures, state of confusion, clinically relevant psychiatric diseases.
15. Presence of significant heart disease or disorder according to ECG.
16. Presence of suspicious undiagnosed skin lesions or a history of melanoma.
17. Previous history of Neuroleptic Malignant Syndrome (NMS) and/or nontraumatic rhabdomyolysis.
18. Presence or history of significant glaucoma.
19. Use of prescription medications including MAO inhibitors within 28 days before day 1 of the study.
20. Use of over-the-counter (OTC) products within 7 days before day 1 of the study.
21. Maintenance therapy with any drug, or significant history of drug dependency (drug abuse) or alcohol abuse (\> 3 units of alcohol per day, intake of excessive alcohol, acute or chronic).
22. Any clinically significant illness in the previous 28 days before day 1 of this study.
23. Use of any enzyme-modifying drugs, including strong inhibitors of cytochrome P450 (CYP) enzymes (such as cimetidine, fluoxetine, quinidine, erythromycin, ciprofloxacin, fluconazole, ketoconazole, diltiazem and HIV antivirals) and strong inducers of CYP enzymes (such as barbiturates, carbamazepine, glucocorticoids, phenytoin and rifampin), in the previous 28 days before day 1 of this study.
24. Volunteers who took an Investigational Product (in another clinical trial) or donated 50 mL or more of blood in the previous 28 days before day 1 of this study.
25. Poor motivation, intellectual problems likely to limit the validity of consent to participate in the study or limit the ability to comply with the protocol requirements or inability to cooperate adequately, inability to understand and to observe the instructions of the physician.
26. Donation of 500 mL or more of blood (Canadian Blood Services, Hema-Quebec, clinical studies, etc.) in the previous 56 days before day 1 of this study.
27. Positive urine screening of ethyl alcohol or drugs of abuse at admission to any treatment period.
28. Any history of tuberculosis and/or prophylaxis for tuberculosis.
29. Positive results to HIV, HBsAg or anti-HCV tests.
