Comparing nurse-led and allergist-led penicillin allergy testing
This study compares two ways of evaluating penicillin allergies: one where a nurse works with an allergist, and another where only an allergist does the evaluation. If you have a penicillin allergy on record, this trial may help find out which approach works better.

Immunotherapy with donor NK cells for relapsed neuroblastoma
This trial studies a “quadruple immunotherapy” treatment using donor immune cells (NK cells) to fight neuroblastoma that has come back or did not respond to prior therapy. It may help by boosting the body’s immune attack, but only certain children meet the safety and donor requirements.

This study looks at whether being sensitive to nickel or certain proteins called LTPs is linked to ongoing stomach and bowel problems. It aims to find better ways to diagnose and help people with functional dyspepsia or irritable bowel syndrome.
NaplesAges 4–65 - NCT07198789Recruiting
Low-sugar carbs for better fat and sugar levels
This study tests whether special carbohydrates that release sugar slowly (low glycemic index) can improve your blood fats (triglycerides) and other health markers better than regular whole grains. If you have moderately high triglycerides, this diet swap might help your metabolism and blood vessels.
Bologna, BOAges 18 years+ - NCT07626606Recruiting
Gut Health and Rotavirus Vaccine Response in Adults
This study examines how the health of your digestive system affects how well your body responds to an oral rotavirus vaccine (a vaccine given by mouth to protect against rotavirus infection). You'll have two endoscopy procedures—a camera test to look inside your digestive tract—and provide samples to help researchers understand this connection.
Lusaka, Lusaka ProvinceAges 18–50 - NCT07230639RecruitingPhase 2
Shorter radiation with chemo and immunotherapy for high-risk colon cancer
This trial tests a shorter course of radiation combined with chemotherapy and an immunotherapy drug (PD-1 inhibitor) for people with a specific type of high-risk colon cancer that has not spread. The goal is to see if this approach can shrink the tumor before surgery and improve outcomes.
Guangzhou, GuangdongAges 18–75 - NCT07082179RecruitingPhase 2
Immunotherapy plus chemotherapy for stage III lung cancer
This trial tests combining immunotherapy with chemotherapy for people with stage III non-small cell lung cancer that cannot be removed by surgery. It aims to see if this combination can shrink the tumor and improve outcomes.
NanjingAges 18–75 - NCT07081698Recruiting
Walnuts as a first solid food for healthy babies
This study tests whether adding walnuts (ground into a powder or paste) as a first solid food is safe and healthy for breastfed babies. It may help families understand how to introduce nuts early.
Fort Collins, ColoradoAges 5 months–5 months - NCT07229742RecruitingPhase 2
Study of SHR-2173 for active lupus nephritis
This trial tests a new medicine called SHR-2173 for people with active lupus nephritis, a kidney inflammation caused by lupus. The goal is to see if it is safe and effective.
Nanjing, JiangsuAges 18–70 - NCT04331522Recruiting
Food or antibiotic allergy testing with controlled allergen exposure
This trial studies people who may have an allergy to certain foods or antibiotics by giving small, controlled exposures to help confirm what’s causing reactions. If your symptoms match, the results could help your doctors guide safer food or medication choices.
Odense, Odense CAges birth–18 years - NCT07527247RecruitingPhase 2
