A5406: Pharmacokinetics and Safety of Double-dose Dolutegravir When Used with Rifapentine for HIV-associated Tuberculosis
A5406 is a study for people with pulmonary drug-sensitive (DS) tuberculosis (TB) without evidence of resistance to the TB drugs isoniazid (INH) or rifampin (RIF) and with HIV. All participants will receive anti-TB treatment (2HPZM: 8 weeks of rifapentine [RPT]-moxifloxacin [MOX] plus INH and pyrazinamide, then 2HPM: 9 weeks of RPT-MOX plus INH). Dolutegravir (DTG)-based anti-HIV therapy (ART) will be taken from week 6 until the end of the study (week 48), with a double-dose of DTG for the first 12 weeks.
A5409: A Phase 2 Randomized, Adaptive, Dose-Ranging, Open-Label Trial of Novel Regimens for the Treatment of Pulmonary Tuberculosis (RAD-TB)
The standard of care (SOC) treatment of tuberculosis (TB) was developed over 40 years ago, and the treatment is long (6 months) and hard. In many settings, the medicine does not work well because people stop taking it or miss doses, which leads to TB returning. For some people, the SOC treatment can cause negative side effects.
This study will evaluate new medication regimens for the treatment of TB. This study is adaptive, which means, as new medication regimens are identified for the treatment of TB, some of them will be selected for testing in this study. Therefore, there may be different drug regimens being used as part of the study at different times.
A5403: Giving Standardized Estradiol Therapy In Transgender Women to Research Interactions with HIV Therapy: the GET IT RIgHT Study
Transgender women (TW) are the fastest-growing group of people with HIV. Historically, TW have had few opportunities to participate in research, and often experience barriers to engaging in care. More research is needed to help providers when it comes to choosing HIV medications in TW on Feminizing Hormone Therapy (FHT). This is an open-label, non-randomized trial of adult TW on three types of HIV medications who will receive estradiol for FHT for 48 weeks.
A5354: Effect of Antiretroviral Treatment Initiated During Acute HIV-1 Infection on Measures of HIV-1 Persistence and on HIV-1-Specific Immune Responses
Will evaluate whether starting antiretroviral drugs very early in HIV infection will limit the virus from getting into hidden areas of the body (reservoirs) and change how the immune system helps to control the virus.
This study will include people who have very recently been infected with HIV and will start anti-HIV (antiretroviral) drugs right away to see how this may change HIV’s impact on the body.
A5321: Decay of HIV-1 Reservoirs in Participants on Long-Term Antiretroviral Therapy: The ACTG HIV Reservoirs Cohort (AHRC) Study
AHRC (pronounced “ARC”) is a study of differences and changes over time in HIV reservoirs (groups of HIV-infected cells that “hide” from anti-HIV medications). This study enrolls people into one of six groups, based on their different HIV treatment histories. The current version of this study is only enrolling for Group 6, which will include people who acquired or are suspected to have acquired HIV while taking long-acting cabotegravir (LA CAB) for pre-exposure prophylaxis (PrEP).
HIV comorbidities and complications
A5243: Non-US Genomic Sampling
Collecting blood and saliva samples from former and current ACTG study participants for future HIV-related genetic testing.
This is a study to collect blood and saliva samples from former and current participants in AIDS Clinical Trial Group (ACTG) studies at non-U.S. sites.
HIV comorbidities and complications
A5332: REPRIEVE Trial
In this study, people between the ages of 40 and 75 with HIV will be randomized (like flipping a coin) to take the pill pitavastatin OR a placebo (non-active pill) to see if pitavastatin can help prevent heart disease and death in people who are taking HIV medication. You will not know if you are taking pitavastatin or placebo. The REPRIEVE trial will enroll about 7500 people from several countries.
A5300B/I2003B: Protecting Households On Exposure to Newly Diagnosed Index Multidrug-Resistant Tuberculosis Patients (PHOENIx MDR-TB)
This trial is in household contacts (HHC) at high risk for developing multidrug resistant tuberculosis (MDR-TB) which is an infection that does not get better with standard treatment for TB. HHC means any person that lives with, has lived with, or shared housekeeping duties in a home or the same place with a person (an Index Case) who has pulmonary MDR-TB (a lung infection or pneumonia with TB) and started treatment for MDR-TB within the past 90 days. It is also for people who have spent more than 4 hours indoors with the index case, during the week before they started MDR-TB treatment.
High-risk household contacts are those with HIV or an immune system problem not from HIV like cancer , latent TB infection (a history of TB infection in the past based on testing), and young children below the age of 5 years.
A5379: B-ENHANCEMENT OF HBV VACCINATION IN PERSONS LIVING WITH HIV (BEe-HIVe): Evaluation of HEPLISAV-B
A5379 is a study looking at hepatitis B vaccination in adults living with HIV. Hepatitis B is a serious viral infection that affects the liver and is transmitted through blood and body fluids. The study will involve individuals who have received a previous hepatitis B vaccination but the vaccine did not respond well and individuals who have never received the vaccination. The study will take place both in the US and internationally. The study will compare how well an individual responds to the vaccine in different groups based on the type of vaccine and number of doses.
