Brief Summary:
Rifampin (RIF) is used for the treatment of tuberculosis (TB), an infectious disease that affects many people with HIV. RIF was shown to lower concentrations and decrease the effectiveness of some anti-HIV drugs, including the HIV protease inhibitor (PI) atazanavir (ATV) boosted with ritonavir (RTV). The purpose of this study is to determine the interactions between RTV-boosted ATV and evaluate the safety and tolerability of giving these drugs together in HIV uninfected adults.
Detailed Description:
TB is common in resource-limited countries, and people infected with HIV are especially at risk for TB infection. The antituberculous drug RIF lowers plasma concentrations of PIs by increasing the activity of enzymes responsible for PI breakdown. RIF has been shown to reduce PI effectiveness, a particular concern for HIV infected patients who are also being treated for TB. RTV has been shown to delay the plasma clearance of ATV and increase the plasma half-life of ATV. This study will evaluate the safety, tolerability, and pharmacokinetic (PK) interactions of RTV-boosted ATV, taken concurrently with RIF in HIV uninfected people.
Medical and medication history, a complete physical exam, blood collection, and an electrocardiogram (ECG) will occur at screening. Participants will be enrolled in this study for 41 to 58 days; there will be 3 dosing periods. From Days 1 to 8, participants will receive 600 mg RIF every 24 hours. From Days 9 to 19, participants will receive 300 mg ATV and 100 mg RTV every 12 hours and 600 mg RIF every 24 hours. From Days 20 to 27, participants will receive 400 mg ATV and 100 mg RTV every 12 hours and 600 mg RIF every 24 hours. Study visits will occur at entry; at Days 5, 8, 11, 14, 19, 23, and 27; and at an additional visit between Days 41 and 48. Blood and urine collection will occur at all visits. A targeted physical exam, an ECG, and blood collection for PK analysis will occur at Days 8, 19, and 27.
