Aging with HIV may be associated with an earlier development of frailty (weakness) or disability, including difficulties in tests of strength or walking speed. Few treatments have been shown to prevent or slow these impairments in people with or without HIV. Some studies have suggested that the class of drugs called statins, such as pitavastatin, might be helpful in slowing frailty or disability. This might happen by decreasing fat within the muscle, or by decreasing inflammation markers in the blood. This study uses the REPRIEVE Trial (A5332) and the REPRIEVE Mechanistic Substudy (A5333s) to study the impact of pitavastatin on muscle.
Requirements to enter the Study:
- You must already be enrolled in REPRIEVE trial (A5332) and the REPRIEVE Mechanistic Substudy (A5333s)
- Taking pitavastatin or placebo as part of REPRIEVE (A5332)
- Willing to complete study procedures
As part of A5361s, muscle strength and muscle function will be measured at yearly visits. Tests will include repeated chair rises, hand grip strength test, standing balance test and a 12 foot (4 meter) timed walk. Participants will also be asked questions about their physical activity.
CT scans (done already in A5333s) will be looked at carefully for muscle size and fat amount and blood samples (collected in A5332) will be analyzed for changes in biomarkers. No additional CT scans or blood will be collected on A5361s.
Duration of Study:
Participants will be followed for 48 months from the date of enrollment into A5332. Based on their date of enrollment into A5332, participants may be followed between 24 to 48 months.
