Studies for People Living with HIV

A5321 – Observational Study for People with New Confirmed or Suspected HIV Infection After Use of Injectable Cabotegravir for HIV PrEP (Group 6)
Basic Eligibility Criteria

Individuals who have used injectable cabotegravir for PrEP within 90 days of a blood sample concerning for possible HIV infection. Excludes those with HIV RNA >1000 copies/mL or who are currently on antiretroviral therapy (ART).

Study Design

This observational study aims to characterize the HIV reservoir, inflammatory consequences, and viral evolution after breakthrough infection, including after ART initiation. Participants will also be referred to the SeroPrep Study.
A5402 – An Open-Label, Randomized Controlled Trial of Pramipexole versus Escitalopram to Treat Major Depressive Disorder (MDD) and Comorbid MDD with Mild Neurocognitive Disorder (MND) in Persons with HIV
Basic Eligibility Criteria

Adults aged 18–70 living with HIV, with a confirmed diagnosis of MDD, stable on ART for ≥3 months, undetectable viral load, not currently on antidepressants, and able to take oral medication. Those who can become pregnant must test negative and use contraception.

Study Design

This study compares pramipexole extended release versus escitalopram for treating MDD and MDD with MND in people with HIV, while also examining impacts on daily functioning.
A5422 – Safety and Immunogenicity of Stabilized CH505 TF chTrimer Vaccination in Adults Living with HIV-1 on Suppressive Antiretroviral Therapy
Basic Eligibility Criteria

Adults aged 18+ living with HIV-1, on stable ART for ≥2 years, with a CD4+ count ≥200, HIV viral load <50 for the past year, no current Hepatitis B or C infection, and using birth control if applicable.

Study Design

Evaluates the safety and immune effects of an investigational HIV vaccine. Participants receive 10 injections (five per arm) over a year. Random assignment gives a 2-in-3 chance of receiving the vaccine and a 1-in-3 chance of placebo.
A5424 – Menopausal Hormone Therapy for Women Living with HIV (HoT Study)
Basic Eligibility Criteria

Individuals assigned female at birth, ages 40–60, in late perimenopause or early postmenopause, living with HIV, on ART for >1 year, not pregnant, and willing to use contraception and complete a daily diary.

Study Design

This two-group study compares hormone replacement therapy (estradiol gel with or without oral progesterone) to placebo in women with HIV.
GSK 209639 – The Embrace Study - Virologic Efficacy and Safety of VH3810109 + Cabotegravir Compared to Standard of Care (SOC) in Adults Living with HIV
Basic Eligibility Criteria

Adults 18-70 years of age, diagnosed with HIV-1, taking standard HIV treatment for at least 6 months, and who have had a successful response to treatment.

Study Design

The EMBRACE Study is testing a study drug combination to see whether it can maintain a low amount of HIV virus inside the body without daily dosing.
Merck 060 – Phase 2 Study of ISL+ULO Once Weekly in Virologically Suppressed Adults With HIV-1
Basic Eligibility Criteria

Adults living with HIV-1, currently taking BIC/FTC/TAF with good viral control for ≥6 months, and no history of treatment failure. Retesting allowed within 45 days if screening values are borderline.

Study Design

Compares once-weekly ISL+ULO treatment to daily BIC/FTC/TAF by evaluating HIV viral control after 24 weeks.
