Helsingborg, Skåne CountyAges 18 years+ - NCT06749457RecruitingPhase 1/Phase 2
Study of a new drug for healthy adults and kidney patients on dialysis
This trial tests a new drug called AZD7760 in two groups: healthy adults (Phase I) and adults with end-stage kidney disease who are on hemodialysis through a central venous catheter (Phase IIa).

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+ - NCT04665037RecruitingPhase 2
Posaconazole study for infants under 2 with serious fungal infection
This trial tests whether posaconazole, given through a vein or by mouth, can treat invasive fungal infections in children under 2 years old. It may help improve outcomes for infants with hard-to-treat fungal disease.
San Diego, CaliforniaAges 1 day–2 years - NCT06866405RecruitingPhase 3
RSV vaccine boost in a new pregnancy
This study tests whether a second dose of the RSV vaccine during a new pregnancy protects you and your baby from RSV. If you received the RSVpreF or Abrysvo vaccine in a past pregnancy, you may be able to join.
Birmingham, AlabamaAges birth+ - NCT06679140RecruitingPhase 3
Study of Ibuzatrelvir for COVID-19 in high-risk patients
This trial tests if a new medicine called ibuzatrelvir can help people with COVID-19 who have certain health risks avoid severe illness. It is for patients who cannot or choose not to take another COVID-19 pill called Paxlovid.
Little Rock, ArkansasAges 12 years+ - NCT07040319RecruitingPhase 1/Phase 2
Hepatitis C treatment study for pregnant women
This study tests a medicine called glecaprevir/pibrentasvir for pregnant women with hepatitis C, with or without HIV. It aims to see how the medicine works in the body and if it is safe during pregnancy.
Los Angeles, CaliforniaAges 16–45 - NCT06680232RecruitingPhase 1
Gene therapy trial for chronic hepatitis B
This trial tests a gene therapy called PBGENE-HBV for people with chronic hepatitis B who are already on antiviral treatment. The goal is to see if it is safe and can help control the virus.
Boston, MassachusettsAges 18–70 - NCT07708727RecruitingPhase 2/Phase 3
Injectable HIV treatment vs daily pill for new patients
This trial tests a new injectable HIV treatment (GS-3242 plus lenacapavir) compared to the daily pill Biktarvy for people just starting HIV therapy. If you qualify, you would receive shots every few weeks instead of taking a daily pill.
Ft. Pierce, FloridaAges 18 years+ - NCT07246057Recruiting
Improving PrEP access with telehealth and community partners
This study looks at how telehealth can make PrEP (medication that helps prevent HIV) easier to get, by partnering with community organizations in Philadelphia. Researchers want to interview or survey clients and staff to understand what works and what could be improved.
Philadelphia, PennsylvaniaAges 16 years+ - NCT06893939RecruitingPhase 2/Phase 3
Feeding approach for very premature babies
This study compares two ways of starting tiny feedings in very premature babies. The goal is to see if a shorter or longer period of very small feedings leads to better growth and fewer feeding problems. If you are okay with your baby receiving donor breast milk when needed, this trial may be a good fit.
Birmingham, AlabamaAges birth–2 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.
Phoenix, ArizonaAges 12 years+ - NCT07763054Recruiting
Low-dose antifungal prevention for patients with low white blood cell counts
This trial tests a low dose of an antifungal medicine (liposomal amphotericin B) to prevent fungal infections in patients whose white blood cell counts are very low for more than a week. It may help patients who are at high risk for fungal infections and cannot take other antifungal drugs.
Hainan, HainanAges 18–75 - NCT07027475Recruiting
Acute treatment and long-term monitoring for adults with meningitis
This study looks at the best way to treat meningitis in adults right away and then checks how people recover over time. It aims to improve care and recovery for patients.
Fortaleza, CearáAges 18 years+ - NCT07285785RecruitingPhase 4
Rifaximin for children with acute diarrhea
This study tests whether a medicine called rifaximin, taken along with oral rehydration solution, helps children aged 6 to 11 recover faster from acute (short-lasting) diarrhea that is likely caused by a bacterial infection. The study compares rifaximin plus oral rehydration versus oral rehydration alone.
Lynwood, CaliforniaAges 6–12 - NCT05124392Recruiting
Observational study of biomarkers in people at risk for prion disease
This study looks for early signs of prion disease in people who are at risk, using blood tests, spinal fluid, and thinking tests. It hopes to find ways to diagnose and track the disease earlier.
Charlestown, MassachusettsAges 18–85 - NCT07672405RecruitingPhase 2
Sorfequiline-based treatment for new drug-sensitive TB
This study tests a new medicine called sorfequiline, given in a combination regimen, to treat adults with drug-sensitive TB. It aims to see if sorfequiline can work as well as or better than standard treatment and shorten the time to cure.
Port Elizabeth, BethelsdorpAges 18–65 - NCT06602557RecruitingPhase 2
Inhaled antibiotic for lung infection during ECMO support
This trial tests whether adding an inhaled antibiotic (amikacin) to standard IV antibiotics can better treat a serious lung infection (pneumonia caused by Gram-negative bacteria) in patients on a heart-lung machine (ECMO) and a breathing tube. If you or your loved one is on ECMO and has this type of pneumonia, this study may offer a new treatment approach.
ParisAges 18 years+ - NCT05419024RecruitingPhase 2
Imaging and biopsy during a planned HIV treatment pause
This Phase 2 study uses special scans (PET/CT) and tissue sampling (biopsy) to learn what is happening in the body while people with HIV take a planned break from antiretroviral therapy (ART) for up to 90 days. It may help researchers find better ways to control HIV without ongoing treatment, though joining involves careful monitoring during the pause.
Bethesda, MarylandAges 18–100 - NCT05813236Recruiting
