Recruiting studies in California
- NCT05719441RecruitingPhase 2
Antibodies plus early HIV treatment to try for HIV remission
This study tests whether giving special HIV-fighting antibodies along with starting standard HIV medicine soon after infection can help you reach “HIV remission.” It may reduce or delay the return of detectable virus, but you must be willing to follow close monitoring and specific study steps.
Los Angeles, CaliforniaAges 18–70 - NCT05887557Recruiting
Mobile HIV care for people struggling to stay in treatment
This study tests a low-barrier, mobile HIV care program designed with input from patients and other stakeholders to help people stay engaged in care and reach an undetectable viral load. It may help if you’re having trouble keeping regular HIV appointments or staying on treatment.
Oakland, CaliforniaAges 15 years+ - NCT06263426Recruiting
Kidney transplant from donors with HIV: impact on rejection and long-term results
This study tests whether kidney transplants from donors with HIV are safe and effective for people with HIV who need a new kidney. It looks at long-term outcomes like rejection and survival.
Sacramento, CaliforniaAges 18 years+ - NCT02140255RecruitingPhase 1/Phase 2
Intensive early HIV treatment in newborns to aim for remission
This study gives very early, intensive HIV medicine to infants diagnosed with HIV and follows them closely to see if HIV can go into remission (stop being detectable without ongoing treatment). It may help families understand whether treating right after birth can change a child’s long-term HIV outlook.
La Jolla, CaliforniaAges Up to 2 days - NCT05488431RecruitingPhase 2
Bempedoic acid to lower cholesterol and inflammation in HIV
This Phase 2 trial studies whether bempedoic acid can lower cholesterol and inflammation in people with HIV who are already on effective HIV medications. It may help reduce signs of artery inflammation that can contribute to heart and stroke risk.
San Francisco, CaliforniaAges 40 years+ - NCT05642858Recruiting
Learn heart health tips for people living with HIV
This study tests a text-message education program to help people living with HIV manage cardiovascular (heart and blood vessel) health. It may be helpful if you are 40 or older and can use a smartphone to receive messages.
San Francisco, CaliforniaAges 40 years+ - NCT07044297RecruitingPhase 3
A study of a new long-acting shot to prevent HIV
This study tests an investigational long-acting shot (MK-8527) to prevent HIV. It is for HIV-negative people who are at higher risk through anal sex without condoms, and who have not used other long-acting HIV prevention before.
Los Angeles, CaliforniaAges 16 years+ - NCT07473778Recruiting
Study of Lenacapavir for HIV Prevention
This trial tests a new medication, lenacapavir, to see how well it works for preventing HIV. It is for people who want or need PrEP (a medicine to prevent HIV) and are interested in learning about different options.
Beverly Hills, CaliforniaAges 18 years+ - NCT04949464Recruiting
Smoking quit coaching plus lung scans for people with HIV
This study tests a behavior-change program to help people with HIV quit smoking, along with routine low-dose lung CT scans to find warning signs early. It’s a feasibility study, meaning the main goal is to see if the approach is practical and acceptable, and if people can follow through.
La Jolla, CaliforniaAges 45–80 - NCT07682961RecruitingPhase 3
Study of new HIV injection vs. standard injectables
This phase 3 trial tests a new long-acting, injectable two-drug combination (lenacapavir + teropavimab + zinlirvimab) vs. another injectable combo (cabotegravir + rilpivirine) for people whose HIV is already well-controlled on daily oral meds. It aims to see if the new combo can keep the virus under control with fewer injections.
San Francisco, CaliforniaAges 18 years+ - NCT07650916RecruitingPhase 3
A study of two ultra-long-acting HIV shots
This trial tests a new ultra-long-acting injectable combination of cabotegravir and rilpivirine for people with HIV who already have the virus under control. It aims to see if these shots can keep the virus suppressed with fewer doses.
Bakersfield, CaliforniaAges 12 years+ - NCT07216794RecruitingPhase 2
Alendronate trial to reduce hidden HIV
This study tests if alendronate, a bone-strengthening medicine, can shrink the reservoir of HIV that stays in your body even when on treatment. You must have well-controlled HIV on antiretroviral therapy for at least one year but no more than ten years, and meet specific health requirements.
San Francisco, CaliforniaAges 18–65 - NCT07461350Enrolling by invitation
Heart health study in people with and without HIV
This study uses MRI scans to look at how stimulant use and inflammation affect the heart in people with and without HIV. It aims to learn more about heart disease risks and may help guide future care.
San Francisco, CaliforniaAges 30 years+ - NCT06252402RecruitingEarly Phase 1
CAR T cells for HIV: A new immunotherapy study
This trial tests a new type of immune cell, called a CAR T cell, that is designed to target and kill cells infected with HIV. It may help control the virus without needing to take HIV medication all the time.
San Diego, CaliforniaAges 18 years+ - NCT07645287RecruitingPhase 2
New HIV Combination Therapy for People on Biktarvy
This study tests a new HIV medication (GS-3242) combined with lenacapavir against your current Biktarvy regimen. Both are all-oral treatments for people whose HIV is well-controlled.
Beverly Hills, CaliforniaAges 18 years+ - NCT07569029RecruitingPhase 1
HIV vaccine with treatment break to boost immune response
This Phase 1 trial tests two new HIV vaccines (DV700P-RNA and DV701B1.1-RNA) combined with a monitored break from HIV medications in people with well-controlled HIV. The goal is to see if this approach safely strengthens the immune system's ability to fight HIV.
San Francisco, CaliforniaAges 18–60 - NCT05143307Enrolling by invitationPhase 1
Follow-up study for adults who received EBT-101 for HIV
This study checks how adults are doing long-term after receiving an HIV treatment called EBT-101 in an earlier study. It helps researchers understand safety and longer-term effects over time.
San Francisco, CaliforniaAges 18 years+ - NCT01202305Recruiting
Lymph node biopsies to study HIV in different patients
This study uses a small tissue sample from an often-accessible lymph node to learn how HIV affects the body. It may help researchers understand why some people control HIV better than others.

What taking part in a hiv study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
