Impact of Steady State Cobicistat and Darunavir/Cobicistat on the Pharmacokinetics and Pharmacodynamics of Oral Anticoagulants (Rivaroxaban, Apixaban) in Health Volunteers
Impact of Steady State Cobicistat and Darunavir/Cobicistat on the Pharmacokinetics and Pharmacodynamics of Oral Anticoagulants (Rivaroxaban, Apixaban) in Healthy Volunteers
Background:
Rivaroxaban and apixaban are blood thinners. People with HIV may need to take them to treat or prevent blood clots. The anti-HIV drug darunavir (DRV) can increase the amount of these blood thinners in the body. This can cause bleeding or other health problems. The drug cobicistat (COBI) is used to help anti-HIV drugs work better. Researchers want to give healthy people DRV combined with COBI to learn how it affects rivaroxaban or apixaban blood levels.
Objective:
To test blood levels of rivaroxaban or apixaban when taken with COBI and DRV/COBI.
Eligibility:
Healthy volunteers ages 18-65
Design:
Participants will be screened with:
Medical history
Physical exam
Fasting blood and urine tests. (Urine tests will be performed in females of child-bearing potential only)
Participants will have 8 visits; 3 are long (about 10-12 hours) and 5 are about 1 hour. They include:
Baseline and final visits:
Fasting blood and urine tests
Day 1 visit (long day):
Fasting blood and urine tests
Catheter placement: A needle will insert a small tube into the participant's arm vein. Blood will be drawn up to 10 times.

Dose of rivaroxaban or apixaban
Dose of COBI
Day 8 (short day):
Fasting blood tests
Dose of DRV/COBI Participants will receive a bottle containing DRV/COBI tablets to take at home.
Day 13 (long day):
