View clinical trials related to HIV-1 Infection.
Filter by:Participants will be randomized (1:1) to one of two sequences of a vaginal ring (VR) containing 25mg of dapivirine to be inserted monthly for 24 weeks and 200 mg FTC/300 mg TDF oral tablets taken daily for 24 weeks. After completing the randomized sequence of two study product use periods, participants will then select between the two study products to use in the final 24 weeks of the trial. Participants will be able to choose either or neither study product every 4 weeks during the third product use period.
Dapivirine Gel Rectal Safety and PK Study
Since people started taking HIV medications, illnesses related to AIDS have decreased, but other serious illnesses like heart disease (heart attacks) and certain kinds of cancer have increased. Studies show that HIV causes changes in the lining of the arteries and also causes inflammation (irritation) inside the body that may play a role in diseases like heart attacks and strokes. The levels of inflammation and artery lining health can also affect how well your brain works. These changes cannot be felt, but can be measured. Artery lining health can be looked at with a test that uses a blood pressure cuff on your arm to see how the artery responds when air is let in and out of the cuff. An ultrasound (machine that uses sound waves) is used to look at the artery during the test. This test is called Flow Mediated Dilation or FMD for short. Inflammation can be checked with blood tests (blood tests that measure this irritation inside the body that you cannot feel). HIV medications can improve the artery lining health and can partially lower levels of inflammation in the blood; however, these levels of inflammation may not be able to return back to normal. Pravastatin sodium is a medication that is approved by the Food and Drug Administration (FDA) for treating high cholesterol. Pravastatin sodium has also been able to improve the health of the lining of the arteries and lower the level of inflammation in people with other diseases, but has not been studied or approved for this purpose in people who have HIV. This research study will look at the effects of two types of medications used separately or together on the health of the lining of arteries and levels of inflammation in the blood: Atripla (a HIV medication) and pravastatin sodium. This study will also look at the effects of Atripla and pravastatin sodium on cholesterol levels, tests that measure how well you can think and calculate (tests of neurocognitive function), and at the effects of Atripla on the levels of pravastatin sodium in the blood.
