Oral probiotic to prevent complications after stem-cell transplant
This Phase 2 study tests an oral “fecal microbiotherapy” treatment given before and around an allogeneic (donor) stem-cell transplant to help prevent transplant-related complications. It may help by improving gut and immune function during the high-risk transplant period.

Mistletoe extract added to immunotherapy for advanced solid tumors
This trial tests whether adding mistletoe extract (Iscador) to standard immunotherapy can make the treatment safer and boost the immune system's response against advanced solid tumors (excluding skin cancer). If you are already receiving or about to start a checkpoint inhibitor, this study may help understand if the combination works better.

Safety study of EDP-978 in healthy adults
This is an early-stage study testing a new experimental drug called EDP-978 in healthy volunteers to see if it is safe and how the body processes it. Researchers will give participants single or multiple doses and monitor for side effects and how the drug moves through the body.
San Antonio, TexasAges 18–65 - NCT07540221RecruitingPhase 3
Comparing two immune therapy infusions for nerve damage
This study tests whether a new immune therapy called XEMBIFY works as well as a standard treatment (Gamunex-C) for CIDP, a condition where the immune system damages nerves and causes weakness. Both are given as infusions under the skin every three weeks.
Rancho Mirage, CaliforniaAges 18 years+ - NCT07541287RecruitingPhase 2
JADE101 for IgA Nephropathy Kidney Disease
This study tests whether JADE101, a new medicine, can help slow kidney damage in people with IgA nephropathy (a type of kidney disease caused by immune system problems). You'll take it alongside your current blood pressure medications for about 48 weeks.
Chula Vista, CaliforniaAges 18–60 - NCT06690593Recruiting
Gut Microbiome Study for Healthy Adults Age 45+
This study compares the gut bacteria of healthy adults (age 45+) with those who have a blood condition called monoclonal gammopathy. The goal is to see if gut bacteria patterns differ between the two groups.
Guanzhou, GuangdongAges 45 years+ - NCT07535008Recruiting
Dental Cleaning to Prevent Graft-Versus-Host Disease
This study tests whether professional dental cleaning after a stem cell transplant can help prevent chronic graft-versus-host disease (GVHD), a condition where transplanted immune cells attack your body. You'll receive dental cleanings and be followed for one year to see if this simple preventive step reduces GVHD complications.
Seattle, WashingtonAges 18 years+ - NCT07537738Recruiting
Blood test to predict outcomes in MLL acute myeloid leukemia
This study uses a special blood test to see if it can predict which patients with a specific type of acute myeloid leukemia (AML with MLL changes) are more likely to relapse or have better survival. The test may help doctors plan better treatment.
BeijingAges 6–60 - NCT07535554RecruitingPhase 2/Phase 3
New PET scan to detect inflammation in three conditions
This study tests a new type of PET scan (a medical imaging test) that may better detect inflammation in the body compared to the standard scan currently used. Researchers will compare the two scans in patients with fever of unknown origin, IgG4-related disease, or inflammatory back pain.
LeuvenAges 18 years+ - NCT07536529Recruiting
Oxidative Stress in Autoimmune Joint Diseases
This study looks at a type of cellular damage called oxidative stress in people with autoimmune joint diseases like rheumatoid arthritis, psoriatic arthritis, or ankylosing spondylitis. Researchers want to understand how this damage relates to your disease and may help develop better treatments.
Larissa, ThessalyAges 18 years+ - NCT07536152RecruitingPhase 4
Antihistamine to prevent allergic reactions during heart surgery
This study tests whether giving an antihistamine (a common allergy medication) before heart surgery can prevent allergic-type reactions that sometimes happen during the surgery itself. The trial includes children with certain types of congenital heart disease (heart problems present from birth).
Giza, OctoberAges 1–7 - NCT07536503Recruiting
How Sleep Quality Affects Thinking and Function in MS
This study looks at whether better sleep helps people with multiple sclerosis (MS) think more clearly and stay more physically active. Researchers will measure your sleep quality and test your memory and everyday abilities to see if they're connected.
