Study of ARV-6723 alone or with pembrolizumab for advanced solid tumors
This trial tests an experimental drug called ARV-6723, alone or with another drug called pembrolizumab, for people with advanced solid tumors that have not responded to other treatments. The goal is to see if these combinations can help shrink tumors or slow their growth.

Blinatumomab for leftover leukemia in children with B-ALL
This trial tests whether a drug called blinatumomab can clear leftover leukemia cells in children with B-cell acute lymphoblastic leukemia (B-ALL) who still have traces of disease after standard treatment. It aims to reduce the chance of relapse.
Hefei, AnhuiAges 1 month–18 years - NCT06610721Recruiting
Better UTI diagnosis for older adults
This trial tests a panel of markers in urine to see if it can more accurately diagnose urinary tract infections in people aged 65 and older. If successful, it could lead to faster and more precise treatment.
Leiden, South HollandAges 65 years+ - NCT06613256Recruiting
Study of blood vessel cells in different inflammatory conditions
This study looks at blood vessel cells in three groups: healthy adults, patients having major surgery, and critically ill patients with sepsis. It aims to understand how these cells change in different types of inflammation.
Guildford, SurreyAges 18 years+ - NCT07745530Recruiting
How platelets affect HIV reservoirs in the blood
This study looks at how platelets (small blood cells that help with clotting) might influence the hidden HIV that remains in your body even when your viral load is undetectable. The goal is to understand why some people's immune systems don't fully recover despite effective HIV treatment.
TourcoingAges 18 years+ - NCT07744321Recruiting
Bacteria in stool during long ICU stays
This study looks at how certain bacteria (Klebsiella pneumoniae and Enterobacter cloacae) change over time in the stool of ICU patients staying at least 28 days. It aims to understand why these infections occur and how they evolve, which could help improve future care.
CaenAges 18 years+ - NCT07745491Recruiting
AI tool to predict pneumonia after heart surgery
This study uses artificial intelligence to help predict if patients might develop pneumonia after heart or blood vessel surgery. It aims to find warning signs early so doctors can act sooner.
TomskAges 18 years+ - NCT07749508Recruiting
Study on gram-negative bacterial infections
This study looks at infections caused by gram-negative bacteria (a type of bacteria that can cause serious illness). It aims to learn more about these infections and how to treat them, which might help improve care for patients with such infections.
Madrid, MadridAges Any age - NCT07740811Recruiting
Bacteria on double-J stents: risks and effects
This study looks at whether bacteria build up on double-J stents (small tubes that help drain urine) and what that means for your health. By checking the stent and urine samples before and after, doctors hope to learn how to reduce infections and improve care.
CairoAges 18 years+ - NCT07746999Enrolling by invitation
Liver health study for transgender adults
This study looks at liver health in transgender individuals to better understand and improve care. You may join if you are 18 or older and can read and write in English.
Newark, New JerseyAges 18 years+ - NCT07748832Recruiting
Pneumonia germ study in young children
This study looks at how long the bacteria that can cause pneumonia and ear infections stay in a child's nose and throat. It may help researchers understand how these germs spread and how to prevent infections in the future.
Orlando, FloridaAges 4 weeks–4 years - NCT03827694Recruiting
Testing a noninvasive scan for serious lung mold infections in kids
This study uses noninvasive breathing/relates imaging (MRI or CT) to help diagnose mold infections in the lungs in children and young adults. It may help doctors find these infections sooner, especially in people with weakened immune systems.
Little Rock, ArkansasAges 4 months–21 years - NCT02979951Recruiting
IV fosfomycin for serious bacterial infections
This trial studies whether IV (through a vein) fosfomycin can treat severe bacterial infections in adults. It may help people whose infection is covered by the standard fosfomycin use and who need hospital-level care.
Hall in TirolAges 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 - NCT06341543Recruiting
CMV blood test to guide treatment after organ transplant
This study uses a blood test (QuantiFERON-CMV) to help decide whether people with a silent (no symptoms) CMV infection after a solid organ transplant need treatment. If you have a low-to-moderate level of CMV in your blood without fever or organ issues, this trial may help your doctor choose the safest approach.
Grenoble, MarylandAges 18 years+ - NCT06452199Recruiting
Bifidobacterium infantis for newborns study (BEGIN)
This study gives healthy newborns a probiotic supplement called Bifidobacterium infantis to see if it helps with growth, immune health, and reducing inflammation. It may be a safe way to support your baby's early development.
Herning, Central JutlandAges 1 day–1 week - NCT06499233RecruitingPhase 4
Study on preventing pneumocystis pneumonia in autoimmune disease
This trial tests whether a preventive treatment can stop pneumocystis pneumonia (a lung infection) in people with autoimmune inflammatory rheumatic diseases who are taking steroids or other immune-suppressing medicines. It aims to find the safest and most effective way to protect you from this serious infection.
