- •A Body Mass Index >18.5 and <30 kg/m2
- •Ability to swallow numerous large capsules without difficulty
- •Reasonable probability for completion of the study, in the opinion of the investigator
- •Acceptable laboratory values that indicate adequate baseline organ function are required at the time of screening. Laboratory values are considered to be acceptable if severity <= Grade1 based on the AIDS Clinical Trials Group (ACTG) Division of AIDS (DAIDS) Grading Scale. All abnormal laboratory values > Grade 1 (e.g., creatine phosphokinase (CPK), amylase, triglycerides) are subject to approval by the BIPI clinical monitor. Cholesterol <= 240mg/dL at the time of screening is necessary for study entry
- •Acceptable medical history, physical examination and ECG are required prior to entering the study
- •Willingness to abstain from alcohol for 48 hours prior to Study Day 0 and abstain from alcohol for the duration of the study. In addition, Cabernet Sauvignon must not have been ingested within 15 days prior to Day 0 (Visit 2)
- •Willingness to abstain from ingesting grapefruit and grapefruit juice within 15 days of Day 0, Visit 2 and for the duration of the study
- •Willingness to abstain from ingesting Seville oranges, strawberries or strawberry extract, garlic supplements, St. John's Wort, Milk Thistle, or methylxanthine-containing drinks or food (coffee, tea, cola, energy drinks, chocolate, etc) within 72 hours of pharmacokinetic (PK) sampling days
- •Willingness to abstain from use of tobacco products for the duration of the study
- •Urine drug screen negative for illegal non-prescription drugs
- •Negative HIV serology
- •Negative for Hepatitis B surface antigen and Hepatitis C
排除标准
- •Female subjects who are of reproductive potential who:
- •Have a positive serum B-HCG at Visit 1 or 2 or
- •Have not been using regular oral contraception (combined oestrogen and progestogen pill or progestogen only pill) for 3 months and a barrier contraceptive method for at least 30 days prior to Visit 3 (Day 1) or a barrier contraceptive method for at least 3 months prior to Visit 3 (Day 1) or
- •Are not willing to use a reliable method of double-barrier contraception (such as diaphragm with spermicidal cream/jelly or condoms with spermicidal foam)during the trial and 30 days after completion/termination or
- •Are breast-feeding
- •Participation in another trial with an investigational medicine for 30 days prior to Day 0 (Visit 2)
- •Ingestion of any known enzyme altering drug (such as phenothiazines, cimetidine, barbiturates, ketoconazole, fluconazole, rifampin, steroids, and herbal medications) for 30 days prior to Day 0 (Visit 2). Use of any other herbal/complementary treatment must be discussed in advance with the monitor and permission obtained prior to study entry
- •Ingestion of grapefruit, grapefruit juice, and Cabernet Sauvignon within 15 days prior to Day 0 (Visit 2)
- •Ingestion of Seville oranges, strawberries or strawberry extract, garlic supplements, St. John's Wort, Milk Thistle, or methylxanthine-containing drinks or food (coffee, tea, cola, energy drinks, chocolate, etc) within 72 hours of PK sampling days
- •Ingestion of antibiotics within 10 days prior to Day 0 (Visit 2)
- •Inability to comply with investigator's instructions
- •History of gastrointestinal, hepatic, or renal disorders within 60 days
- •History of alcohol abuse
- •Current use of cigarettes defined as greater than 10 cigarettes per day or rolling/pipe tobacco equivalent
- •Blood or plasma donations within 30 days prior to Day 0 (Visit 2)
- •Subjects with a seated systolic blood pressure either <100 mm Hg or >150 mm Hg; resting heart rate either <50 beats/min or >100 beats/min
- •Subjects with a history of any illness or allergy that, in the opinion of the investigator, might confound the results of the study or pose additional risk in administering tipranavir or ritonavir or tenofovir disoproxil fumarate to the subject
- •Subjects who have had an acute illness within 2 weeks prior to Day 0 (Visit 2)
- •Subjects who are currently taking any over-the-counter drug within 7 days prior to Day 0, (Visit 2) or who are currently taking any prescription drug that, in the opinion of the investigator in consultation with the clinical monitor and pharmacokineticist, might interfere with either the absorption, distribution or metabolism of the test substances
- •Hypersensitivity to tipranavir, ritonavir, or tenofovir disoproxil fumarate
