The REPRIEVE (A5332) trial is the first-ever, large scale clinical trial to test a strategy to prevent heart disease among people living with HIV. REPRIEVE showed that pitavastatin can prevent heart disease in this population, and participants in this trial have contributed meaningfully to the pursuit of new medical knowledge. 

FAQ About the Results of REPRIEVE

1What were the main findings of the REPRIEVE trial?
REPRIEVE results revealed that pitavastatin, a statin medication and the heart disease prevention strategy tested in the trial, reduced major heart disease events like heart attacks and strokes in people with HIV by 36% compared to placebo. Pitavastatin also reduced major heart disease events or death from any cause by 23% compared to placebo.
Pitavastatin was effective in both men and women, and the study participants experienced very few safety events.
The results of REPRIEVE have changed clinical guidelines and are helping clinicians to better support the heart health needs of people with HIV. There are many more questions that the REPRIEVE Team is working to answer in the future.
2Why was pitavastatin used in REPRIEVE, and which statin medication is right for me?
Revised treatment guidelines incorporating data from REPRIEVE that recommend statin therapy in this patient population were recently announced and are available here. Pitavastatin was chosen for REPRIEVE because it has minimal interactions with ART and has been shown to lower cholesterol and improve inflammation markers in people with HIV.
If pitavastatin is not available in your area, another statin medication that does not interact with your antiretroviral therapy may be a reasonable choice. Please discuss with your clinician about the choice that is right for you.
3Should I start taking a statin, given the results of REPRIEVE?
Revised treatment guidelines incorporating data from REPRIEVE that recommend statin therapy in this patient population were recently announced and are available here. Before the results of REPRIEVE were known, the decision to take statin medications for people with HIV depended on cholesterol levels and other risk factors for heart and blood vessel (cardiovascular) disease. REPRIEVE has shown that statins prevent heart disease in people with HIV in the absence of high cholesterol or other heart disease risk factors. However, you and your clinician should still consider all of your risk factors, like age, smoking history, and family history for heart attacks and strokes before starting a statin.
4Pitavastatin is not available in my region or it is not covered by my health insurance. Will a different statin medication also protect me from heart disease?
Revised treatment guidelines incorporating data from REPRIEVE that recommend statin therapy in this patient population were recently announced and are available here. Pitavastatin was chosen for REPRIEVE because it has minimal interactions with antiretroviral therapy and has been shown to lower cholesterol and improve inflammation markers in people with HIV. If pitavastatin is not available in your area or your health insurance does not cover it, another statin medications that does not interact with antiretroviral therapy may be a reasonable choice. Please discuss with your clinician about the choice that is right for you.
5Did REPRIEVE participants taking pitavastatin experience any muscle aches or pains?
A small proportion of REPRIEVE participants in REPRIEVE experienced general myalgias (muscle aches and pains), and muscle weakness, and this was slightly more common for participants taking pitavastatin vs. placebo (2.4% vs. 1.5%). But, these symptoms were mostly mild and only 1% of participants withdrew for muscle-related symptoms. These symptoms generally went away after the first year.
6Did REPRIEVE participants taking pitavastatin develop diabetes?
The rates of diabetes were higher for participants taking pitavastatin group compared to participants taking placebo (6.0% vs 4.7%). However, pitavastatin reduced the risk of heart disease even among people with diabetes. It is an important and personal choice to weigh your own risk of diabetes vs. heart disease like a heart attack or a stroke.
7Can someone living with HIV who already had a heart attack or a stroke in the past take a statin to reduce their chance of having another heart attack or stroke?
Yes, from many studies, we know that taking a statin may help prevent a second heart attack or stroke for people who already had a heart attack or stroke. It is important to discuss this with your healthcare provider your individual heart disease history and how best to protect your heart health.
8Is there anything else I can do to protect myself from heart disease?
Don't forget that a healthy lifestyle is still key for preventing heart disease! Lifestyle changes are key for reducing your risk of heart disease, whether you take a statin or not. Data from REPRIEVE have shown that poor heart health is associated with more blockages in the heart arteries, and that heart healthy behaviors can be enhanced in people with HIV. To reduce your risk:
  • Quit smoking and avoid secondhand smoke
  • Eat a healthy diet rich in vegetables, fruits, fish, and whole grains and low in saturated fat, trans fat, refined carbohydrates and salt.
  • Be physically active more often and sit less
  • Maintain a healthy weight

    • FAQ About the REPRIEVE Trial

    1What was the purpose of the REPRIEVE trial?
    Previous studies have shown that people with HIV are at higher risk for heart disease than people without HIV. The REPRIEVE trial tested a strategy to reduce the risk of heart disease–including heart attack and stroke–among people with HIV. In people with HIV, cardiovascular disease risk is thought to be influenced by traditional risk factors–such as cigarette smoking, high blood pressure, diabetes, and high cholesterol–and also by factors unique to HIV, such as chronic inflammation.
    2What are we learning from your participation in REPRIEVE?
    REPRIEVE found that pitavastatin, a statin medication and the heart disease prevention strategy tested in the trial, reduced major heart disease events like heart attacks and strokes in people with HIV by 36% compared to placebo. Pitavastatin also reduced major heart disease events or death from any cause by 23% compared to placebo. Pitavastatin was effective in both men and women, and the study participants experienced very few safety events. The results of REPRIEVE are helping clinicians to better support the heart health needs of people with HIV, and there are many more questions that the REPRIEVE Team is working answer in the future. A few of these questions are listed below:
  • Does pitavastatin help slow or prevent kidney disease in people with HIV?
  • How are people with HIV impacted by COVID-19?
  • What are the potential effects of a daily dose of pitavastatin and/or ART regimens on COVID-19?
  • Is COVID-19 a heart disease risk factor?
    • 3What are statins?
    Statins are medications that lower cholesterol levels in the blood and have also been shown to have anti-inflammatory effects. Statins have already been shown to reduce heart disease in the general population among individuals at high risk for heart disease based on traditional risk factors. At the conclusion of REPRIEVE, we observed that statins reduced heart disease among people with HIV with low to moderate traditional risk scores.
    4How did this trial work?
    Participants were randomized (like flipping a coin) to take either:
    • Pitavastatin calcium (Livalo) 4 mg, one pill daily
    • Placebo for pitavastatin calcium (Livalo), one pill daily
      • Pitavastatin calcium (Livalo) is a statin that has been approved by the US Food and Drug Administration for the treatment of high cholesterol, even though not all participants in the trial had high levels of cholesterol, as per the trial design. Advice on healthy diet and exercise was given to all participants in the trial. Pitavastatin calcium (Livalo) has been shown to be safe in individuals taking antiretroviral (ART) medications.
    5How many people participated in the REPRIEVE trial?
    REPRIEVE enrolled over 7500 people with HIV into the trial from around the world.
    6How long did it take to finish the REPRIEVE trial?
    Participants had visits approximately every 4 months during the trial. The median length of trial participation for individual participants was about 5 years.
    7Where was the REPRIEVE trial conducted?
    The REPRIEVE trial was conducted at research sites in United States, Canada, Thailand, South Africa, Brazil, Peru, Haiti, Zimbabwe, Botswana, Uganda, and India. Over 100 research sites enrolled participants into REPRIEVE. A map is posted providing links to participating sites, as well as contact information for the site.
    8Are there any substudies or ancillary studies that are a part of the REPRIEVE trial?

    There are 6 substudies and ancillary studies that are part of the REPRIEVE trial, including 2 additional study objectives included in REPRIEVE, they are:

    The Mechanistic Substudy of REPRIEVE (ACTG A5333s) is trying to understand ways in which statin therapy may achieve a reduction in cardiovascular disease. Some possible ways include:

    1. lowering cholesterol levels
    2. lowering the degree of inflammation
    3. stabilizing fatty plaques in the blood vessels surrounding the heart, preventing these plaques from rupturing.

    805 participants enrolled in the REPRIEVE substudy and the last visit was completed summer of 2020. Substudy participants had some additional tests and monitoring, including CT scan of the heart’s blood vessels.

    Pitavastatin to REduce Physical Function Impairment and FRailty in HIV (PREPARE) [ACTG #A5361s]

    PREPARE is an observational study of muscle strength and function among people with HIV who are receiving pitavastatin or placebo as part of the REPRIEVE study (A5332) and are also enrolled in the Mechanistic substudy (A5333s). 600 REPRIEVE participants are also participating in the PREPARE substudy.

    Sex-Specific Mechanisms of Cardiovascular Disease Risk and Risk Reduction

    This project is exploring among participants in REPRIEVE, sex-differences in immune activation in relation to heart disease events and statin-related heart disease prevention. This project is also assessing how menopause influences heart disease risk and risk reduction specifically among women with HIV.

    Evaluation of the Effects of Pitavastatin on Kidney Function in Persons with HIV

    To evaluate the effects of pitavastatin on clinical and subclinical kidney function and to investigate the relationship between chronic kidney disease and cardiovascular disease.

    Clonal Hematopoiesis of Indeterminate Potential (CHIP) and Incident Cardiovascular Outcomes

    The objective is to estimate the prevalence of & characterize risk factors for CHIP in PWH, associate CHIP with incident clinical outcomes in PWH, and discover mechanistic relationships of CHIP with HIV-associated outcomes.

    Mechanisms of Cardiac Dysfunction in HIV and the Effect of Statins: A Cardiac MRI Study

    This is a study assessing mechanisms of cardiac dysfunction among individuals with HIV on antiretroviral therapy and the effects of pitavastatin on myocardial fibrosis, myocardial steatosis, and cardiac function. Approximately 120 REPRIEVE participants also participated in this study and underwent additional testing including cardiac MRI.

    9Who funds the REPRIEVE trial?
    REPRIEVE is funded by the National Heart Lung and Blood Institute (NHLBI) at the National Institutes of Health (NIH), with significant support and collaboration from the National Institute of Allergy and Infectious Diseases (NIAID) through its Division of AIDS (DAIDS). In addition, Kowa Pharmaceuticals America, Inc. is donating pitavastatin and providing support for the study. Gilead Sciences, Inc. and ViiV Healthcare are also providing support. The REPRIEVE trial is a collaboration of government agencies, academic centers, research institutes and industry support working in partnership to determine if pitavastatin can reduce the risk of cardiovascular disease in people with HIV.
    10How did COVID-19 impact people with HIV?
    The REPRIEVE team is evaluating whether participants randomized to statin (vs. placebo) experienced protection from developing COVID-19 or serious COVID-19. REPRIEVE trial leadership received a grant from the NIH National Heart Lung and Blood Institute (NHLBI) to carry out this investigation.
