Improve how HIV prevention and treatment services are integrated
This study looks at ways to better connect HIV prevention services with HIV treatment services in participating clinics. It mainly involves interviewing clinic leaders and staff, plus public health staff, to learn what’s working and how to improve care.
MombasaAges Any age - NCT05406037Recruiting
Testing blood and tissue markers for invasive mucormycosis
This study looks for specific lab “biomarkers” in people with mucormycosis, a serious fungal infection. It compares results with people who have higher infection risk but no active infection, to help doctors diagnose and track this illness more accurately.

This is an observation study that compares outcomes after two types of skull repair: PEEK and titanium. It may help doctors understand which option works best and how patients recover, without requiring an experimental treatment plan.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT05418088RecruitingPhase 1
CAR T-cell therapy for hard-to-treat B-cell cancers
This Phase 1 study tests lab-made immune cells (CAR T-cells) that target CD19, CD20, and/or CD22 in people with certain relapsed or refractory B-cell cancers. It may help by attacking cancer cells that still carry these targets, but eligibility is very specific and includes prior treatments and health/lab requirements.
Columbus, OhioAges 2 years+ - NCT05418868RecruitingPhase 1
Long-acting cabotegravir injection safety in healthy adults
This Phase 1 study tests how the body handles a long-acting (slow-release) cabotegravir injection combined with a drug called hyaluronidase. It also checks safety and side effects in healthy adults to help future HIV-prevention or treatment plans.
Orlando, FloridaAges 18–55 - NCT05422508RecruitingPhase 2
Second chickenpox shot for healthy kids after one prior vaccine
This study gives a second chickenpox vaccine dose to healthy children who were vaccinated once before. It mainly checks safety and measures the body’s immune response to see how well the second dose works.
AnsanAges 4–6 - NCT05424302Recruiting
Home virtual reality therapy for vestibular problems by location
This study looks at how well a home-based virtual reality (VR) vestibular therapy works for people with ongoing (chronic) balance problems, and whether results differ based on where the problem is in the inner ear. It may help your care team understand who benefits most from VR therapy.
Vancouver, British ColumbiaAges 18 years+ - NCT05425524Recruiting
Hospital care bundle study for suspected leptospirosis
This trial tests a structured set of hospital treatments (“care bundle”) for adults with suspected leptospirosis, a serious infection often linked to flood water exposure. It may help by improving how quickly and consistently key care steps are delivered in the hospital.
Bangkok, BangkokAges 18 years+ - NCT05425264Recruiting
Home exercise coaching by video after COVID
This trial tests a home-based exercise and physical therapy program delivered by video after a COVID-19 infection. It may help you rebuild strength and breathing safely, especially if you also have certain long-term health conditions.
Baltimore, MarylandAges 50–85 - NCT05426720Recruiting
Looking for TB lung damage risk factors and blood markers
This study looks at what increases the risk of long-term lung damage after active pulmonary tuberculosis (TB). It also tests whether certain blood or other markers can predict who is more likely to have lung problems later.
BeijingAges 25–60 - NCT05431101Recruiting
Absorbable versus non-absorbable stitches after carpal tunnel surgery
This study compares two types of stitches used to close the skin after carpal tunnel release surgery. It may help show which stitch type leads to better healing and comfort afterward.
ApeldoornAges 18 years+ - NCT05432336Recruiting
Testing better lab diagnosis for serious eye infections
This study looks at how doctors collect and test eye infection samples to get more accurate results, especially in serious cases like corneal abscess or deep eye infection. If you have signs of a complex eye infection and a sample is needed, this trial may help improve the way diagnosis is done for patients like you.
Paris, IDFAges 18 years+ - NCT05432362Recruiting
Energy sensing brain study in depression and weight groups
This study tests how the brain and body respond to “energy sensing” in people with depression and in people with different body weights. You may be asked to do assessments and follow specific health and diet rules so the researchers can compare groups.
Graz, StyriaAges 18–40 - NCT05434104Recruiting
Trial tests vaginal lactoferrin instead of medicines for BV or thrush
This study checks whether using lactoferrin vaginal pessaries can work for bacterial vaginosis (BV) or thrush, compared with standard antibiotic or antifungal tablets. It’s a feasibility study, meaning the main goal is to see if the approach and home sample collection are practical.
LondonAges 16–50 - NCT05442515RecruitingPhase 1/Phase 2
CAR T-cell treatment for hard-to-treat B-cell cancers in youth
This trial tests a personalized immune-cell therapy (CAR T cells) made to attack B-cell cancers that have come back or did not respond to prior treatment. It aims to see how well the treatment works and how safe it is in children and young adults.
Bethesda, MarylandAges 3–39 - NCT05442710RecruitingPhase 2
Immune cell treatment for recovery from severe septic shock
This trial tests an immune-cell treatment given outside the body to help people recover from septic shock, a life-threatening reaction to infection. It aims to improve survival and organ recovery in patients who are still very ill despite standard care.
Freiburg im Breisgau, Baden-WurttembergAges 18 years+ - NCT05443178RecruitingPhase 1
Testing chloroquine added to tuberculosis treatment for safety
This Phase 1 study tests how safe and tolerable chloroquine is when given alongside standard tuberculosis medicine. It mainly involves healthy volunteers and helps researchers understand side effects and safe dosing.

Baricitinib to help reduce HIV in the brain
This Phase 2 study tests baricitinib to see if it can lower HIV activity in the brain (CNS) for people already on stable HIV treatment. If you have well-controlled HIV in your blood, this trial looks for additional benefit inside the nervous system.
