This trial tests whether a natural product can quickly change your immune system. It is looking for healthy adults who can keep a steady diet and lifestyle for the study period.
Klamath Falls, OregonAges 18–75 - NCT06276088Recruiting
SAA1 levels to predict cancer immunotherapy response
This trial measures a protein called SAA1 in your blood and tumor tissue to see if it can predict how your cancer will respond to immunotherapy. It aims to understand why some patients have rapid tumor growth after treatment.
Guangzhou, GuangdongAges 18 years+ - NCT07208058RecruitingPhase 3
Testing plonmarlimab for blood cell overactivation in people with rheumatic disease
This trial tests a new drug called plonmarlimab for people with a rheumatic (joint or immune) disease who also have a dangerous overreaction of their immune system called HLH (or MAS). The goal is to see if the drug can help when high-dose steroids have not worked or are not an option.
Beijing, Beijing MunicipalityAges 16–80 - NCT06271343Recruiting
Kidney transplant tolerance study
This trial is testing a way to help your body accept a kidney transplant without needing lifelong anti-rejection drugs. It is for people getting a kidney from a living donor who is a relative and has a compatible blood type.
Nantes, Loire-AtlantiqueAges 18 years+ - NCT06234761Recruiting
Study on immune responses in nasal polyps
This trial looks at how the immune system reacts in people with nasal polyps. It may help doctors better understand and treat this condition.
GhentAges 18 years+ - NCT06199427RecruitingPhase 2
Preventing graft-versus-host disease after stem cell transplant for immune disorders
This trial tests a combination of two drugs, ruxolitinib and PTCy, to prevent graft-versus-host disease (a common complication) in children receiving a stem cell transplant for inborn errors of immunity. The goal is to make the transplant safer and more effective.
MoscowAges birth–21 years - NCT07187583RecruitingPhase 4
Reducing biologic doses for chronic sinusitis with polyps
This trial tests if patients with chronic sinusitis and nasal polyps can safely reduce how often they take their biologic medication (dupilumab or mepolizumab) after their disease has been partly controlled for at least a year.
AalborgAges 18 years+ - NCT07081126Recruiting
Daratumumab for late antibody-mediated rejection in kidney transplant
This trial tests whether daratumumab can help treat a type of rejection that happens more than a year after a kidney transplant. It may be an option for people who have biopsy-proven antibody-mediated rejection and new donor-specific antibodies.
MartinAges 18 years+ - NCT06997471RecruitingPhase 1
Safety of modified stem cell infusion with organ transplant
This early-phase trial tests whether it is safe to give a special type of stem cell transplant (with the naïve T cells removed and only memory T cells left) to people receiving organ transplants. It is for children getting intestine or lung transplants, and for children or adults getting kidney transplants.
Madrid, MadridAges birth+ - NCT06203249Recruiting
Exploring lung health and immune system in a rare muscle disease
This trial looks at how the immune system and tiny organisms in the lungs may affect a rare condition called anti-MDA5 positive dermatomyositis, which can cause serious lung disease. It may help doctors understand why some patients get worse quickly and how to better treat them.
Beijing, Beijing MunicipalityAges 18–100 - NCT06162494Enrolling by invitationPhase 4
Shingles vaccine study for young adult transplant recipients
This study tests the shingles vaccine in young adults who have had a solid organ transplant (like a kidney or liver) more than a year ago. The goal is to see if the vaccine works well and is safe for people on stable anti-rejection medicines.
Chicago, IllinoisAges 19–40 - NCT06154538RecruitingPhase 2
Immunotherapy plus chemo vs. chemo alone for advanced colorectal cancer before surgery
This trial tests whether adding immunotherapy (a treatment that helps your immune system fight cancer) to standard chemotherapy before surgery works better than chemotherapy alone for people with locally advanced colorectal cancer.
