Recruiting studies
- NCT04339777RecruitingPhase 2

This trial studies how well a donor bone marrow (stem cell) transplant works for people with inherited immune system problems (called immune deficiencies). It’s for patients who haven’t improved with usual treatment or don’t have another good option.
Bethesda, MarylandAges 4–69 - NCT06930976Recruiting
Tracing sugar use in immune cells
This study uses a special sugar (glucose) to see how your immune cells use energy. You drink a labeled sugar, then give blood samples so researchers can track it.
Nashville, TennesseeAges 18 years+ - NCT05306925Recruiting
Arginine supplement study for newborns after major gut surgery
This study looks at whether giving an amino-acid supplement called arginine to newborns after major bowel surgery can improve the baby’s immune response. It may help doctors understand how to support recovery after conditions like necrotizing enterocolitis or certain birth defects.
Liverpool, MerseysideAges 5 months–10 months - NCT05273138Recruiting
Study of skin immune and support cells in systemic sclerosis
This study looks at skin cells and immune cells in people with systemic sclerosis to better understand what drives the disease. Your participation may help researchers learn how the immune system and skin support cells change over time.
LilleAges 18 years+ - NCT06842316Recruiting
Study on cannabis-like compounds for inflammatory arthritis
This trial tests whether plant-based compounds similar to cannabis (called phytocannabinoids) can help calm inflammation and improve immune function in people with certain types of arthritis or autoimmune diseases like lupus or Sjögren's disease. It aims to offer a new way to treat these conditions without the 'high' of marijuana.
OrléansAges 18 years+ - NCT05139706Recruiting

Klamath Falls, OregonAges 18–75 - NCT04871932Recruiting
Study of immune response to a COVID-19 vaccine
This trial studies how your immune system responds after a COVID-19 vaccine. It uses detailed blood tests to understand what changes happen in your immune cells and may help researchers improve future vaccines.
ShanghaiAges 18–50 - NCT05354765Recruiting
Collect immune cells by lymphapheresis to study cancer response
This trial studies how changing your immune system (with earlier treatments) affects cancer by collecting immune cells from your blood using a process called lymphapheresis. It may help researchers find better ways to monitor immune-related responses and side effects.
ParisAges 18 years+ - NCT07292493Enrolling by invitation
Immune system study for diabetic kidney disease
This study looks at how the immune system works in people with diabetic kidney disease. It tests whether certain blood pressure medicines can help protect the kidneys.
LjubljanaAges 40–65 - NCT06540027Enrolling by invitation
Minimally invasive surgery for rectal cancer inflammation
This study looks at how different types of surgery (open, laparoscopic, or robotic) affect inflammation throughout the body in people with rectal cancer. It may help doctors understand which approach is gentler on your immune system.
IstanbulAges Any age - NCT05507242RecruitingPhase 2
Drug that blocks TSLP to reduce COPD flare airway inflammation
This Phase 2 trial tests whether blocking TSLP can reduce inflammation in the airways of people with COPD, especially around flare-ups. If you often need prednisone and/or antibiotics for COPD exacerbations, this study may help determine a new treatment approach.
CopenhagenAges 40 years+ - NCT07127705Recruiting
How stem cells and immune cells respond to a supplement
This trial tests how a supplement affects your stem cells and immune cells over time. It may help researchers understand if the supplement supports your body's natural defenses.
Klamath Falls, OregonAges 18–75 - NCT05648136Recruiting
Blood test study for immune markers in miscarriage and IVF failure
This study looks at immune-related blood patterns and other measurements to better understand why some women have repeated pregnancy loss or repeated IVF implantation failure. If you qualify, your answers and test results may help researchers identify biomarkers that could guide future care.
Amiens, PicardieAges 18–39 - NCT07220915RecruitingPhase 3
Study of Panzyga to prevent infections in people with weak immune systems
This trial tests if a medication called Panzyga can help prevent infections in people with autoimmune conditions who have low antibody levels after B-cell therapy. It may be an option if you have a condition like multiple sclerosis, rheumatoid arthritis, or lupus.
Scottsdale, ArizonaAges 18 years+ - NCT06996652RecruitingPhase 2
Study of adalimumab to delay Parkinson's symptoms in sleep disorder
This trial tests whether adalimumab, an immune system drug, helps people with REM sleep behavior disorder (a condition that may warn of Parkinson's disease) stay healthy longer. Participants will receive injections of the drug or a placebo to see if it prevents Parkinson's-related brain problems.
Los Angeles, CaliforniaAges 50–80 - NCT06286644Recruiting
Hops compounds and your immune system
This study looks at how compounds found in hops (used in beer) affect your immune system. If you are a healthy adult, you may join and help researchers learn more about how these natural substances work.
ViennaAges 18–70 - NCT05334888Recruiting
Study how sex and gut bacteria relate to heart risk
This study follows people over time to understand how sex-related factors and gut bacteria may affect heart and blood-vessel risk. It may help researchers identify who could benefit from earlier prevention, based on personal risk patterns.
BerlinAges 18–50 - NCT05655273Enrolling by invitationPhase 4
Switch tacrolimus timing after liver transplant to Envarsus
This trial looks at whether changing your maintenance anti-rejection medicine from Prograf (usually twice daily) to Envarsus (once daily) can help keep your liver and kidney function stable. It targets people who may be having kidney side effects, symptoms from tacrolimus, or trouble taking a twice-daily medicine.
Toronto, OntarioAges 18–99 - NCT02257892Recruiting
Study of rare immune system genetic disorders
This study looks for genetic causes of immune problems, such as unusually frequent infections, abnormal allergies, or autoimmune or inflammation conditions. It may help by improving how doctors understand these disorders and by matching families with possible genetic diagnoses.
Bethesda, MarylandAges 3–99 - NCT06745102Recruiting
Hop compounds for immune health in people with extra weight
This trial tests if compounds from hops can help the immune system of people who are overweight and showing early signs of metabolic issues like prediabetes, fatty liver, or mild high blood pressure.
ViennaAges 18–75 - NCT07024238Enrolling by invitation
Short-chain fatty acid supplement for kidney transplant patients
This study tests whether taking a short-chain fatty acid (a type of fiber-like substance) supplement can improve gut health in people who have had a kidney transplant. It may help keep the transplant working well.

Steroids versus standard heart medications for heart inflammation
This study compares two treatment strategies for people with unexplained heart failure and irregular heartbeats caused by inflammation: one group gets standard heart medications plus an immune-suppressing steroid (prednisone), and the other gets standard medications alone. Doctors want to see whether adding steroids helps improve heart function and control dangerous heart rhythms.
Phoenix, ArizonaAges 18 years+ - NCT07632911Enrolling by invitation
How Exercise Affects Your Immune System
This study looks at how different types of exercise—aerobic (like running) and resistance (like weightlifting)—change how your immune system works. Researchers will track your immune health over time to understand which exercise style might boost immunity best.

Common questions
- Are there clinical trials for immune system?
- Yes. Clin2 currently lists 130 recruiting immune system studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a immune system trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a immune system trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
