Exploratory Analysis Associates HIV Drug Abacavir with Elevated Cardiovascular Disease Risk in Large Global Trial
July 23, 2024
Current or previous use of the antiretroviral drug (ARV) abacavir was associated with an elevated risk of major adverse cardiovascular events (MACE) in people with HIV, according to an exploratory analysis from a large international clinical trial primarily funded by the National Institutes of Health (NIH). There was no elevated MACE risk for the other antiretroviral drugs included in the analysis. The findings will be presented at the 2024 International AIDS Conference (AIDS 2024) in Munich, Germany.
NIH Awards More than $20 Million to International HIV Database Centers
July 22, 2021
The National Institutes of Health has renewed grants to seven regional centers that compose the International epidemiology Databases to Evaluate AIDS (IeDEA), awarding $20.8 million in first-year funding. The 15-year-old IeDEA program efficiently advances knowledge about HIV by pooling and analyzing de-identified health data from more than two million people with HIV on five continents to answer research questions that individual studies cannot address. The grants are expected to last five years and to total an estimated $100 million.
Too Many People with HIV Fail to Achieve Durable Viral Suppression
November 29, 2021
Among people with HIV worldwide who are receiving antiretroviral therapy (ART), adults are getting closer to the global target of 95% achieving viral suppression, but progress among children and adolescents is lagging and long-term viral suppression among all groups remains a challenge.
Novel Vaccine Concept Generates Immune Responses that Could Produce Multiple Types of HIV Broadly Neutralizing Antibodies
May 30, 2024
Using a combination of cutting-edge immunologic technologies, researchers have successfully stimulated animals’ immune systems to induce rare precursor B cells of a class of HIV broadly neutralizing antibodies (bNAbs). The findings, published today in Nature Immunology, are an encouraging, incremental step in developing a preventive HIV vaccine.
An Isolated Viral Load Test May Generate False Positive Results for People Using Long-Acting PrEP
July 23, 2024
A single laboratory-based HIV viral load test used by U.S. clinicians who provide people with long-acting, injectable cabotegravir (CAB-LA) HIV pre-exposure prophylaxis (PrEP) did not reliably detect HIV in a multi-country study. In the study, a single positive viral load test was frequently found to be a false positive result. However, a second viral load test with a new blood sample was able to distinguish true positive results from false positive results for all participants whose initial viral load test was positive.

July 23, 2024
Long-acting injectable cabotegravir (CAB-LA) was safe and well tolerated as HIV pre-exposure prophylaxis (PrEP) before and during pregnancy in the follow-up phase of a global study among cisgender women. The analysis of outcomes from more than 300 pregnancies and infants will be presented at the 2024 International AIDS Conference (AIDS 2024) in Munich, Germany.
Long-Acting HIV Treatment Benefits Adults with Barriers to Daily Pill Taking and Adolescents with Suppressed HIV
March 6, 2024
Long-acting, injectable antiretroviral therapy (ART) suppressed HIV replication better than oral ART in people who had previously experienced challenges taking daily oral regimens and was found safe in adolescents with HIV viral suppression, according to two studies presented today at the 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver. Both studies were sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, in collaboration with other NIH institutes.
NIH Trial of Rectal Microbicide for HIV Prevention Begins in the United States
October 31, 2024
A clinical trial has launched to examine the safety and acceptability of a novel rectal HIV microbicide douche containing the antiretroviral drug tenofovir. While HIV incidence is slowly decreasing in the United States, 67% of U.S. HIV diagnoses from 2018-2022 were among gay, bisexual, and other men who have sex with men, pointing to the need for expanded HIV prevention options. The mid-stage study is sponsored by the National Institutes of Health’s National Institute of Allergy and Infectious Diseases and implemented through the NIH-funded HIV Prevention Trials Network.
Children Surpass a Year of HIV Remission after Treatment Pause
March 6, 2024
Four children have remained free of detectable HIV for more than one year after their antiretroviral therapy (ART) was paused to see if they could achieve HIV remission, according to a presentation today at the 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver. The children, who acquired HIV before birth, were enrolled in a clinical trial funded by the National Institutes of Health in which an ART regimen was started within 48 hours of birth and then closely monitored for drug safety and HIV viral suppression.
Semaglutide Reduces Severity of Common Liver Disease in People with HIV
March 5, 2024
A weekly injection of semaglutide was safe and reduced the amount of fat in the liver by 31% in people with HIV and metabolic dysfunction-associated steatotic liver disease (MASLD), according to a presentation today at the 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver. This is the first clinical trial of semaglutide for MASLD in people with HIV.
Vaginal Ring and Oral Pre-Exposure Prophylaxis Found Safe for HIV Prevention Throughout Pregnancy
March 5, 2024
The monthly dapivirine vaginal ring and daily oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate and emtricitabine were each found to be safe for HIV prevention among cisgender women who started using one of them in their second trimester of pregnancy, according to findings presented today at the 2024 Conference on Retroviruses and Opportunistic Infections (CROI) in Denver. Pregnant people are estimated to be three times more likely to acquire HIV through sexual intercourse than similarly aged people who are not pregnant.
Early HIV diagnosis and treatment important for better long-term health outcomes

October 20, 2022
A three-dose course of the hepatitis B vaccine HEPLISAV-B fully protected adults living with HIV who had never been vaccinated against or infected with the hepatitis B virus (HBV), according to study findings presented today at the IDWeek conference in Washington, D.C. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, sponsors the ongoing Phase 3 ACTG A5379 clinical study.

July 24, 2023
A National Institutes of Health-supported study found that statins, a class of cholesterol-lowering medications, may offset the high risk of cardiovascular disease in people living with HIV by more than a third, potentially preventing one in five major cardiovascular events or premature deaths in this population. People living with HIV can have a 50-100% increased risk for cardiovascular disease.
NIH Clinical Trial of Tuberculous Meningitis Drug Regimen Begins
December 7, 2023
A trial of a new drug regimen to treat tuberculous meningitis (TBM) has started enrolling adults and adolescents in several countries where tuberculosis (TB) is prevalent. The trial will include 330 participants aged 15 years and older who have or are likely to have TBM based on signs and symptoms, including people living with and without HIV. Because pregnant women are eligible to enroll in this study with appropriate consent, a small number of pregnant women are expected to be included.
