Testing a new antifungal for mold infections in immunocompromised people
This study tests a new antifungal drug (EL219) compared to two standard treatments (liposomal amphotericin B or voriconazole) for people with weakened immune systems who have a suspected or confirmed mold infection. The goal is to see if the new drug works as well or better at treating the infection.

Tissue samples from people with viral infections or cancer
This study collects tissue and blood samples from people who have or have been exposed to certain viruses (HIV, KSHV, HPV, EBV, or HTLV-1) or who have developed cancer or precancerous skin lesions. The samples help researchers understand how these viruses may lead to cancer.

Testing DARE-HPV to Clear Persistent HPV Infection
This study tests whether DARE-HPV, a new treatment, can help your body clear a persistent human papillomavirus (HPV) infection that hasn't gone away on its own. HPV is a common virus; persistent infection with certain high-risk types can lead to cervical cancer, so clearing it early may prevent future problems.

Fatigue study using digital outcomes in multiple sclerosis and long COVID
This study is investigating fatigue using digital outcomes in people with multiple sclerosis, long COVID, and healthy volunteers. Participants must own a smartphone, be fluent in German or English, and be willing to provide informed consent. Exclusion criteria include having taken certain medications recently, being pregnant or lactating, or having additional health conditions that could affect fatigue or the autonomic nervous system.

Testing a new catheter to reduce infections and blockages
This study tests a new type of urinary catheter (called 'NowCath Foley') to see if it reduces infections and blockages compared to standard catheters. If you use a long-term catheter and are under community nursing care, this might be relevant for you.
HerningAges 18 years+ - NCT07781878Recruiting
Skin staples vs stitches for planned belly surgery wounds
This trial compares two ways to close the skin after a planned belly operation: using metal staples or traditional stitches. Participation may help doctors learn which method leads to better healing and fewer wound problems.
Islamabad, CapitalAges 15–50 - NCT07783243Recruiting
Leishmaniasis vaccine response study in Ethiopia
This study tests how your immune system responds to parts of a potential vaccine for leishmaniasis. Doctors will take small blood or skin samples to see if your body's cells react to these vaccine pieces, which could help design a better vaccine in the future.
Addis AbabaAges 18–65 - NCT07706413Recruiting
Plasma exchange for children with severe sepsis
This trial tests whether removing harmful substances from the blood (plasma exchange) can help children with severe infections that cause organ failure or very low blood pressure. If your child is in the hospital with severe sepsis or septic shock and is between 1 month and 18 years old, this treatment might be an option.
Shibīn al Kawm, Menoufia GovernorateAges 1 month–18 years - NCT06293352Recruiting
Comparing two antibiotic spacers for knee infection
This trial compares two types of antibiotic spacers for people with a long-term knee replacement infection. It tests whether a spacer made entirely of antibiotic cement or one with a metal core works better to treat the infection before a new knee replacement.
Chicago, IllinoisAges 18 years+ - NCT07706647Recruiting
Oil pulling for gum health trial
This study tests if oil pulling (swishing oil in your mouth) can reduce gum inflammation and bleeding. It compares oil pulling to a standard mouthwash to see which is better for gum health.
San Antonio, TexasAges 18–70 - NCT07499544RecruitingPhase 3

This study tests a new drug, Libevitug, for people with chronic hepatitis D (HDV). It aims to see if the drug can help control the virus and improve liver health.
Garden Grove, CaliforniaAges 12–70 - NCT04405700Recruiting
Tracking birth outcomes and birth defects after delivery
This study follows pregnant people and their babies to better measure adverse outcomes and possible congenital (from birth) conditions. It may help improve how birth risks and birth defects are identified and recorded at the clinic.
