TMC435350 is a protease inhibitor (PI), a class of drugs that selectively inhibit the replication of the virus thereby inhibiting the progression of HCV infection. Plasma levels of TMC435350 are circulating levels of TMC435350 in the blood that are important for the antiviral activity of TMC435350. Ritonavir has the ability to increase the circulating levels of other compounds administered on the same day as Ritonavir. The trial will consist of 2 sequential sessions (Session 1 and Session 2) and all participants enrolled in the study will enter each session. In Session 1, participants will take TMC435350 200mg orally (by mouth) once daily for 7 days. There will be a waiting period of at least 7 days to allow any drug left in the body after the last treatment in Session 1 to be eliminated before the start of Session 2 (referred to as a "washout period"). In Session 2, participants will take ritonavir 100 mg orally twice daily on Days 1 to 15 and TMC435350 200mg once daily on Days 6 to 12. All study drugs in both treatment sessions will be taken under fed conditions (i. e., participants will eat a standard breakfast within approximately 30 minutes before they take study drug). Full pharmacokinetic profiles of TMC435350 (to investigate how the drug moves through the body, including the absorption, distribution, metabolism and elimination of the drug) will be determined from blood samples obtained on Days 1 and 7 of Session 1 and on Days 6 and 12 of Session 2. Safety and tolerability will be recorded continuously. The total duration of treatment in the study for each participant will be approximately 30 days (includes 7 days of treatment in Session 1, 16 days of treatment in Session 2, and a washout period of at least 7 days between treatment sessions).'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* non-smoking for at least 3 months prior to selection\n\n * normal weight as defined by a Quetelet Index (Body Mass Index: weight in kg divided by the square of height in meters) of 18.0 to 30.0 kg/m2, extremes included\n * Informed Consent Form signed voluntarily, prior to the first trial related activity\n * normal 12-lead electrocardiogram (ECG) at screening\n * healthy on the basis of a medical evaluation and results fo the laboratory tests at screening.\n\nExclusion Criteria:\n\n* past history of heart arrhythmias,\n\n * female, except if postmenopausal for more than two years, or post-hysterectomy or post-tubal ligation (without reversal operation)\n * history or evidence of current use of alcohol, barbiturate, amphetamine, recreational or narcotic drug use\n * hepatitis A, B and C infections or human immunodeficiency virus type 1 (HIV-1) or HIV-2 infections at study screening\n * donation of blood or plasma in the 60 days preceding the first intake of trial medication'}, 'identificationModule': {'nctId': 'NCT01891851', 'briefTitle': 'A Study of Drug-drug Interaction Between Ritonavir and TMC435350 in Healthy Volunteers', 'organization': {'class': 'INDUSTRY', 'fullName': 'Tibotec Pharmaceuticals, Ireland'}, 'officialTitle': 'Phase I, Open-label Trial in Healthy Subjects to Evaluate the Drug-drug Interaction Between Ritonavir at Steady-state and TMC435350, a Viral Protease Inhibitor Against Hepatitis C Virus, After the First and the Last Dose of a Multiple Dosing Regimen', 'orgStudyIdInfo': {'id': 'CR014773'}, 'secondaryIdInfos': [{'id': 'TMC435350-TiDP16-C104', 'type': 'OTHER', 'domain': 'Tibotec Pharmaceuticals Limited, Ireland'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'TMC435350 / Ritonavir', 'description': 'TMC435350 2 capsules of 100-mg twice daily / Ritonavir one 100-mg capsule twice daily', 'interventionNames': ['Drug: TMC435350 200 mg', 'Drug: Ritonavir 100 mg']}], 'interventions': [{'name': 'TMC435350 200 mg', 'type': 'DRUG', 'description': 'Each patient will receive 200 mg (2 capsules) once daily orally from Day 1 to Day 7 in Session 1 and from Day 6 to Day 12 in Session 2', 'armGroupLabels': ['TMC435350 / Ritonavir']}, {'name': 'Ritonavir 100 mg', 'type': 'DRUG', 'description': 'Each patient will receive 100 mg (1 capsule) of ritonavir twice daily orally from Day 1 until Day 15 of Session 2', 'armGroupLabels': ['TMC435350 / Ritonavir']}]}, 'contactsLocationsModule': {'locations': [{'city': 'Aalst', 'country': 'Belgium', 'geoPoint': {'lat': 50.93604, 'lon': 4.0355}}], 'overallOfficials': [{'name': 'Tibotec Pharmaceuticals Limited, Ireland Clinical Trial', 'role': 'STUDY_DIRECTOR', 'affiliation': 'Tibotec Pharmaceuticals, Ireland'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Tibotec Pharmaceuticals, Ireland', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
