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.

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 - NCT07735221Recruiting
Peanuts for stress and heart health
This trial tests whether eating peanuts every day can reduce stress, improve immune function, and lower inflammation in people who feel stressed. If you are stressed and generally healthy, you may qualify.
Davis, CaliforniaAges 18–65 - 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 - NCT04791488Recruiting
Testing oxygen level effects after diving or oxygen therapy
This study looks at how breathing extra oxygen (hyperoxia) and the body’s immune response change after diving or when people need hyperbaric oxygen therapy. It may help doctors understand what to expect and how to manage recovery after a diving accident.
ToulonAges 18 years+ - NCT07861854Recruiting
How young children fight flu: a nose and blood study
This study looks at how children's bodies protect against flu by checking their nose and blood. It aims to find better ways to prevent flu in young kids.
Jouberton, North WestAges 2–5 - NCT06331988Recruiting
Study of colon cancer, bacteria, and the immune system
This study looks at how bacteria in your gut, your immune system, and colon cancer interact. It aims to understand these connections to improve future treatments.
MilanAges 18–75 - NCT06390696Recruiting
Sand play for eczema: a biodiversity study
This study looks at whether playing in sand with different types of natural materials (to increase your contact with harmless microbes) can improve eczema symptoms. You would stop using your usual eczema creams during the trial to see if the sand play alone helps.
Helsinki, UusimaaAges 2–5 - NCT06271252RecruitingPhase 1
Study of OriCAR-017 for relapsed or refractory multiple myeloma
This trial tests a new type of CAR-T cell therapy called OriCAR-017 for people with multiple myeloma that has come back or not responded to treatment. It is for patients who have already tried several treatments, including ones that target BCMA, and their last treatment stopped working.
Atlanta, GeorgiaAges 18–75 - NCT05098821Recruiting
Study factors that affect eczema control on dupilumab
This trial studies why eczema (“atopic dermatitis”) varies in severity even when people receive the medicine dupilumab. It may help doctors better predict who responds well and how to monitor treatment.
BerlinAges 18–75 - NCT07733362Recruiting
Spirulina Protein Capsule Immune Health Study
This trial tests whether a spirulina protein capsule can help support the immune system in healthy adults. It may be a safe option for those looking to maintain immune function.
Phayao, Changwat PhayaoAges 25–60 - NCT06631937Recruiting
How infant feeding affects gut health and immunity
This study looks at how different feeding methods (like breast milk or formula) affect the development of healthy bacteria in a baby's gut and their immune system. It may help us understand what helps babies stay healthy.
AarhusAges birth–4 weeks - NCT06683248Recruiting
Night shifts and menstrual cycle health study
This study looks at how working night shifts affects your health throughout your menstrual cycle. It aims to help understand the risks and support better health for shift workers.
Uppsala, Uppsala CountyAges 18–35 - 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.
MalatyaAges 18–35 - NCT05432362Recruiting
Energy sensing brain study in depression and weight groups
This study tests how the brain and body respond to “energy sensing” in people with depression and in people with different body weights. You may be asked to do assessments and follow specific health and diet rules so the researchers can compare groups.
Graz, StyriaAges 18–40 - NCT06470607Recruiting
Lung tumor immune cell study for surgery patients
This study looks at immune cells inside lung tumors to better understand how they work. If you are having surgery for a thoracic tumor, your tissue could help researchers learn more.

Common questions
- Are there clinical trials for immune system?
- Yes. Clin2 currently lists 126 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.
