Study for children with severe strep skin or bloodstream infection
This trial is for people under 18 who have a confirmed invasive Group A strep infection, meaning strep bacteria found in places that are normally sterile (like the blood or deep tissues). It tests whether a specific study approach can help improve outcomes for children with these serious infections.
CréteilAges 1 day–17 years - NCT05789901Recruiting

Montreal, QuebecAges 14 years+ - NCT05790889RecruitingPhase 1/Phase 2
Study of an experimental malaria vaccine in babies in Burkina Faso
This Phase 1/2 study tests a new vaccine meant to protect young children against malaria. If you qualify, your baby would get the study vaccine and be followed for about 12 months to check safety and early signs of protection.
Siglé, Boulkiemdé ProvinceAges 5 months–1.4 years - NCT05791396RecruitingPhase 1/Phase 2
Fecal microbiome therapy to clear hard-to-treat gut germs
This trial looks at a treatment made from stool donors (called fecal microbiome therapy) to help remove carbapenem-resistant gut bacteria in the body. It’s mainly for adults who recently tested positive for these bacteria on a rectal swab, and it checks whether the therapy can help eradicate the germs.
RomaAges 18–85 - NCT05794880Recruiting
Immunotherapy lowering immune cells before transplant in children
This trial tests a special immune-cell “preparation” treatment (called T-cell and B-cell depletion) with adjusted anti-thymocyte globulin (ATG) dosing before a stem cell transplant. It aims to reduce immune-related transplant complications in people under 25 with certain blood cancers in a specific remission status.
Milwaukee, WisconsinAges birth–25 years - NCT05796505Recruiting
Community outreach to improve vaccine acceptance in prisons
This study tests community engagement approaches to help people in prison feel more comfortable accepting vaccines. It will focus on people in regular housing areas, and it may help increase vaccine willingness through trusted local outreach.
Schwenksville, PennsylvaniaAges 18 years+ - NCT05797415Recruiting
Check sentinel lymph node biopsy for several eye skin cancers
This trial studies whether a “sentinel lymph node biopsy” can better detect cancer spread in people with specific cancers of the eye surface and nearby tissues. It may help doctors find the right next treatment by learning whether lymph nodes are involved.
Roma, RomeAges 18–95 - NCT05797649Recruiting
Test a pleural fluid blood marker to tell heart failure vs others
This study checks whether a substance called NT-proBNP in pleural fluid can better identify if fluid around the lung is caused by heart failure. If you fit, the results may help doctors choose faster, more accurate diagnosis for your pleural effusion.
Hong Kong, New TerritoriesAges 18 years+ - NCT05805605RecruitingPhase 2
Low-intensity stem cell transplant with donor cells and blood-protection
This Phase 2 study tests a low-intensity bone marrow/stem cell transplant using a matched donor plus two medicines to help prevent the donor cells from attacking you. It aims to treat certain blood cancers—especially when standard treatment has not fully worked or when you are in remission but at higher risk.
Minneapolis, MinnesotaAges Up to 75 years - NCT05807399RecruitingPhase 2
Step2c trial for new, drug-susceptible lung TB
This Phase 2 study tests treatment for people with newly diagnosed, drug-susceptible pulmonary (lung) tuberculosis (TB). It aims to see whether the study treatment works well and is safe for curing TB.
LambarénéAges 18–65 - NCT05806762Recruiting
Wearable patch study to predict sepsis rehospitalization
This study uses a wearable skin patch placed on you during a sepsis hospital stay to help predict whether you might need to be readmitted after discharge. It may help doctors identify who is at higher risk of rehospitalization and plan follow-up care earlier.
San Diego, CaliforniaAges 18 years+ - NCT05807867Recruiting
Support program to help women with HIV keep treatment working
This study tests a stigma-reducing support program to help women living with HIV and serious mental illness stay adherent to HIV treatment. It focuses on sustaining viral suppression by addressing stigma that can make care harder, and it involves family and community leaders as part of the approach.
GaboroneAges 18–65 - NCT05814250Recruiting
Ultrasound in children after a first bladder infection
This trial studies whether doing an ultrasound scan after a child’s first febrile urinary tract infection (UTI) is useful. The goal is to see which children might need further attention based on the scan.
FlorenceAges 2 months–3 years - NCT05814237Recruiting
Study of new respiratory infections starting within 10 days
This is an observational study that follows adults who are newly sick with a respiratory infection that started within the past 10 days. It may help researchers understand what causes these infections and how patients do in emergency or hospital-care settings.
BrusselsAges 18 years+ - NCT05816083Recruiting
Virtual reality tool for teens and young adults after trauma
This study tests a virtual reality program to help young people who have been through serious violence or sexual assault (“ITE”). It’s also open to certain healthcare workers who support these young people.
Charleston, South CarolinaAges 15–30 - NCT05819229Recruiting
Antibiotics by mouth only for young babies with urine infection
This trial studies whether giving antibiotics by mouth alone is enough to treat a urinary tract infection (UTI) in very young babies. It may help reduce the need for stronger or more invasive antibiotic approaches if you meet the study’s stability and urine-test requirements.
CopenhagenAges 4 weeks–2 months - NCT05821478RecruitingPhase 3
Antibiotics plan for hidradenitis stage 2 flares
This Phase 3 study tests whether an adapted antibiotic treatment works better than the standard approach to control hidradenitis suppurativa (HS) symptoms and flares. It may help people with stage 2 HS reduce active inflammation and flare-ups.
MarseilleAges 18–59 - NCT05821075RecruitingPhase 1/Phase 2
Prednisolone vs Cerebrolysin for sudden facial weakness
This early-stage study compares two medicines—prednisolone and cerebrolysin—to see which works better for Bell’s palsy (sudden one-sided facial weakness with no clear cause). You may be asked to take one of the study treatments and be followed to measure how well facial movement improves.
GizaAges 18–60 - NCT05822141Recruiting
Omega-3 effects on body fat in cold exposure
This study tests whether omega-3 (fish oil–type) changes how your body fat responds when you are exposed to cold. It may help researchers understand how to regulate “brown fat,” which can be involved in how your body uses energy during cold.
Bloomington, IndianaAges 18–40 - NCT05822193Recruiting
Study of long COVID in Brazil
This study looks at how often “post-COVID-19 condition” (long COVID) happens, what factors are linked to it, and how much it affects people’s daily lives. It may help researchers better understand long COVID and who is most impacted.
Cachoeirinha, Rio Grande do SulAges 18 years+ - NCT05824442Recruiting
Testing a new PCR test for echinococcosis diagnosis
This study checks whether a new lab test (a PCR blood/tissue test) can more accurately diagnose echinococcosis. It may help doctors confirm the infection faster and more reliably so you can get the right treatment.

Oral drug for rifampicin-resistant lung tuberculosis
This Phase 3 trial tests an oral medicine (Sudapyridine/WX-081) to treat people with rifampicin-resistant pulmonary tuberculosis. It compares how well the study drug works when you stop prior tuberculosis medicines and go through a short “washout” period first.
Beijing, Beijing MunicipalityAges 18–65 - NCT05824988Recruiting
Testing antibiotic dose levels for MAC lung infection
This trial studies how much medicine is needed (based on lab results) to treat MAC lung disease, an infection in the lungs. If you already have MAC and are receiving the recommended core antibiotics, your care may help researchers link treatment details to lab measurements.
ShanghaiAges 18 years+ - NCT05826067Recruiting
Testing E. coli from repeat urinary infections
This study collects and studies bacteria (E. coli) found in urine from people with urinary tract infections, including those with repeat infections. It may help improve how doctors understand these infections and choose better future treatments.
