A5385: An Observational Post-Intervention Cohort Destination Protocol

This study is a two-step, non-interventional extension study for individuals participating in another interventional HIV cure trial (parent study) that includes an analytical treatment interruption (ATI) (stopping anti-HIV therapy [ART] while monitoring viral load). Participants will be individuals who achieved post-intervention control (PIC) (maintaining HIV suppression after treatment interruption) in their parent study.

Step 1 will consist of an extended ATI period in which PICs will be monitored for safety, viral, and immune outcomes. Time to viral rebound and restart of antiretroviral therapy (ART) will be measured. Participants will begin Step 2 if they meet ART restart criteria and will be monitored for safety, immune, and viral outcomes through 48 weeks after ART restart.

A5374: A Phase I/IIa Randomized, Placebo-Controlled Trial of Conserved-Mosaic T-cell Vaccine in a Regimen with Vesatolimod and Broadly Neutralizing Antibodies in Adults Initiated on Suppressive Antiretroviral Therapy during Acute HIV-1

Current antiretroviral therapy (ART) does not cure HIV. ART just holds the virus in check so it cannot multiply and destroy the immune system. When most people talk about a cure for HIV, they generally imagine a cure that would remove all virus from the body. However, many researchers are looking for a different approach, known as a functional cure, that would improve the immune system response to HIV so that it controls the virus and allows for longer periods during which a person with HIV could stop taking ART.

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.

A5384: A Phase II, Randomized, Open-Label Trial of a Six-Month Regimen of High-Dose Rifampicin, High-Dose Isoniazid, Linezolid, and Pyrazinamide versus a Standard Nine-Month Regimen for the Treatment of Adults and Adolescents with Tuberculous Meningitis

Study Description

A5384 is a trial for people who have or might have tuberculous meningitis (TBM). TBM is an infectious disease that causes inflammation of the membranes that surround the brain and the spinal cord (meninges). TBM is caused by the bacterium Mycobacterium tuberculosis, which can be found elsewhere in the body, usually the lungs, but can travel via the bloodstream to the meninges, where the bacteria cause TBM.

This trial will compare a new experimental regimen of anti-TBM medicines taken over a 6-month time period with the current standard of care regimen of anti-TBM medicines taken over a 9-month time period.

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).

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.
