Johor Bahru, JohorAges 18 years+ - NCT06337292RecruitingPhase 3
Wound vacuum therapy for high-risk leg fractures
This trial tests if a special wound vacuum (negative pressure therapy) applied after surgery can lower the risk of infections and other complications in people with severe leg fractures. If you have a high-risk tibia or ankle fracture, this treatment may help you heal better.
Baltimore, MarylandAges 18 years+ - NCT06338124Recruiting
Lab tests to predict outcomes in sepsis patients
This study looks at whether certain blood test results can help predict how well people with sepsis will do. Sepsis is a serious infection that can affect the whole body. You may be able to join if you have sepsis and are over 18.
AsyutAges 18–70 - NCT06338215Recruiting
Moderate drinking vs. abstention advice for adults
This study compares two approaches for adults who drink regularly: advice on drinking in moderation vs. advice to stop drinking entirely. The goal is to see which approach better prevents major diseases and early death over time.
Pamplona, NavarreAges 50–75 - NCT06339203Recruiting
Saline vs. special antiseptic for c-section wound cleaning
This study compares cleaning the wound with plain salt water versus a diluted antiseptic solution after a planned C-section. The goal is to see which method better prevents infections for mothers with certain health conditions.
Loma Linda, CaliforniaAges 18 years+ - NCT06340737RecruitingPhase 1
CD22-targeting CAR T cells for relapsed B cell lymphoma
This trial tests whether giving modified immune cells (CAR T cells) that target CD22 on cancer cells can help people with certain B-cell lymphomas that have come back or not responded to at least two prior treatments. The goal is to see if this approach can shrink tumors or control the disease.
Palo Alto, CaliforniaAges 18 years+ - 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+ - NCT06342752Recruiting
Breath test for early lung disease in premature babies
This trial studies a breath test to predict lung disease in very premature babies. It could help doctors start treatment earlier to prevent serious breathing problems.
Edegem, AntwerpAges birth–3 days - NCT06343090Recruiting
Comparing two CAR T cell treatments for children and adults with B-ALL
This trial tests whether giving two types of CAR T cells (CD19 and CD22) one after the other works better than giving just one type (CD19) followed by a stem cell transplant for people whose B-cell acute lymphoblastic leukemia (B-ALL) has come back or not gone away. The goal is to see which approach offers a better chance of long-term remission.
Beijing, Beijing MunicipalityAges 1–70 - NCT06346665Recruiting
