Breastfed infants of HIV-exposed mothers get a probiotic
This study gives a specific probiotic (from B. infantis) to babies born without HIV to see if it can improve the baby’s early immune health. It focuses on babies who are HIV-exposed because their mother has HIV and plans to exclusively breastfeed for the first 6 months.

Stopping antibiotics after 3 days for high-risk neutropenia
This study tests whether it is safe to stop broad antibiotics after 3 days in people at high risk of infection from low white blood cells (neutropenia) who are hospitalized with fever. It may reduce antibiotic exposure, while still watching closely to keep you safe.

Using frailty scores to predict death in ICU sepsis
This trial checks whether a “frailty” rating (how physically/mentally vulnerable someone is) can predict the risk of death in ICU patients with sepsis shock. It may help doctors identify higher-risk patients earlier and tailor care.
BéthuneAges 18–65 - NCT05931497Recruiting
Sauna heat treatment for long COVID fatigue
This trial tests whether regular sauna sessions using infrared heat can reduce fatigue from long COVID. You may be eligible if you have ongoing fatigue after a confirmed or strongly suspected COVID infection and can safely spend time lying in a sauna.

Early blood-pressure support in the emergency department
This Phase 3 study tests whether starting a blood-pressure medicine earlier in the emergency room can improve outcomes for people with low blood pressure or shock. It focuses on patients who have already received enough IV fluids and meet specific blood pressure and lab findings.
CopenhagenAges 18 years+ - NCT05934149Recruiting
Lupus health registry that stores samples for future research
This study keeps a long-term record of people with lupus (systemic lupus erythematosus) and collects samples so researchers can study the disease better. You may be able to join if you meet lupus diagnosis criteria, are not pregnant, and can follow the study visits and consent process.
Birmingham, AlabamaAges 18–110 - NCT05934305Recruiting
Help for shame and stigma in HIV and substance use
This study tests whether a program can reduce shame and stigma for people living with HIV who also have a substance use disorder. It may help you feel less judged and cope better, while supporting HIV care.

Arginine supplements to help prevent pregnancy complications
This study tests whether taking an arginine-based supplement during pregnancy can help lower the risk of bad pregnancy outcomes. You may be eligible if you are pregnant in the early-to-mid period and meet safety and location requirements.
KisumuAges 16–40 - NCT05935683Recruiting
Registry for severe, uncontrolled chronic sinusitis in Italy
This trial is a registry that enrolls people with severe, hard-to-control chronic sinusitis. It helps doctors better understand this specific type of inflammation and how it affects symptoms and quality of life.
Rozzano, MIlanAges 18 years+ - NCT05936073Recruiting
Study of patient data for people with HDV infection
This study looks at patient information (your health data) for adults who test positive for HDV. You may help researchers better understand HDV by allowing their team to collect and use your data.
LimogesAges 18 years+ - NCT05937178Recruiting
Real-World Study to Optimize Hepatitis B Tablet Treatment
This study looks at how to best use existing hepatitis B “nucleotide-analog” tablets in everyday care. It may help tailor when to start, and whether to continue or adjust treatment, based on your test results.
Hefei, AnhuiAges 18–80 - NCT05938192Recruiting
Treatments for HPV-related genital tract changes
This trial studies treatment approaches for conditions caused by human papillomavirus (HPV) in the female genital tract. It may help people whose HPV-related disease is being evaluated for new or combined treatment options.
Milan, LombardyAges 18 years+ - NCT05939167RecruitingPhase 1/Phase 2
Stem cell treatment study for people with late-stage HIV
This Phase 1/2 study tests whether mesenchymal stem cells can help people with HIV who have lower immune cell counts. You would join a treatment plan and follow study rules closely, while the researchers track safety and early signs of benefit.
BeijingAges 18–65 - NCT05941052Recruiting
Testing new at-home TB checks in the clinic
This study tests new tools that can check for tuberculosis (TB) more quickly at or near where care happens. It includes people with cough or TB risk factors, and also the health workers who perform TB testing, to see how well the tests work and how easy they are to use.
AbujaAges 12 years+ - NCT05943548Recruiting
Traditional healer support to help HIV reach low viral levels
This study tests whether support from traditional healers can help people with HIV get their viral load down to very low levels. You may be offered additional support and asked to attend clinic and nurse visits over 2 years.
