Recruiting studies
- NCT05899439Recruiting
Blood test study of immune changes in type 1 diabetes
This study looks at how your immune system changes over time and how that relates to developing type 1 diabetes. You may be able to join if you can have blood drawn, since the study focuses on blood samples.

This study tests whether a personalized, automated physical activity program (using a Fitbit and continuous glucose monitor) can improve immune function and health outcomes in people with advanced ovarian, primary peritoneal, fallopian tube, or newly diagnosed endometrial cancer. You'll wear an activity tracker, answer questionnaires, and provide blood and stool samples at Roswell Park.
Buffalo, New YorkAges 18 years+ - NCT06858683Recruiting
Time-restricted eating study for people with obesity
This study tests if eating only within a certain time window each day can improve immune function in people with obesity who are planning bariatric surgery. You would follow a time-restricted eating plan for 10-12 weeks before your surgery to see how it affects your health.

Alcohol and drug effects on immunity in ICU breathing patients
This study looks at how alcohol and other drugs can affect the body’s immune system in people who are very sick in the ICU due to breathing problems. It may help doctors better understand immune changes during critical illness and respiratory failure.
Aurora, ColoradoAges 18–90 - NCT03240328RecruitingPhase 1
CAR-T therapy study for rebuilding HIV immune defenses
This early-stage study tests whether CAR-T cells can help rebuild the immune system’s ability to fight HIV. You may be a candidate if your HIV is well controlled on standard treatment and you don’t have certain serious infections or organ problems.
Guangzhou, GuangdongAges 18–60 - NCT07490587RecruitingPhase 2
Probiotic study for healthy infant growth and allergy prevention
This trial tests a probiotic supplement (Bifidobacterium animalis subsp. lactis XLTG11) to see if it helps infants grow better and have fewer allergies. It is for healthy babies up to 3 years old who are at higher risk for allergies.
Pudong, Shanghai MunicipalityAges birth–3 years - NCT07676305Recruiting
6-week blood flow restriction exercise and diabetes
This study tests whether a special type of exercise (using bands to partially restrict blood flow to your arms or legs) can improve how your immune cells work and use energy. It's for people with type 2 diabetes who are not very active.
Kelowna, British ColumbiaAges 19–64 - NCT05324475Recruiting
Nutritional supplement to support immunity and energy in older adults
This trial tests whether a safe nutrition supplement can help older adults with malnutrition maintain immune function and energy (mitochondrial function). It may support recovery during rehabilitation, but you must meet specific nutrition and health criteria.
Lausanne, SwitzerlandAges 75 years+ - NCT05586360RecruitingPhase 2
Testing how a statin may change immune markers in prostate cancer
This Phase 2 study tests whether taking simvastatin can change “immune regulation” markers in men with intermediate- to high-risk localized prostate cancer. It also looks at whether this could help lower the risk of cancer coming back after planned prostate surgery.
Atlanta, GeorgiaAges 18 years+ - NCT01351545Recruiting
Cryopreserved cord blood access program for transplant patients
This trial studies an organized way to obtain and distribute unlicensed (not FDA-approved for general use) stored cord blood units that have been frozen and kept. It may help people who need a cord blood transplant but don’t fit the “licensed cord blood only” options.
Birmingham, AlabamaAges Any age - NCT07596316Recruiting
Understanding Immune Response to Chlamydia Infection
This study examines how your body's immune system responds to a Chlamydia trachomatis infection by analyzing urine and blood samples. Researchers hope to better understand infection patterns and improve future treatments.
Antwerp, AntwerpAges 18 years+ - NCT07284641RecruitingPhase 2
Stem cell transplant for immune disorders
This trial tests a stem cell transplant to treat common variable immunodeficiency (CVID) and other immune problems. It aims to replace a faulty immune system with a healthy one from a donor.
Pittsburgh, PennsylvaniaAges 5–40 - NCT05359796Recruiting
Study of long-term type 1 diabetes symptoms and characteristics
This study looks at what day-to-day health and medical features are like in people who have had type 1 diabetes for many years. It may help researchers better understand long-term needs in type 1 diabetes and guide future care.
Changsha, HunanAges Any age - 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.
Martin, SlovakiaAges 18 years+ - NCT06635863Enrolling by invitationPhase 4
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+ - NCT06493669Recruiting
Immune cells, muscle, and memory in aging
This study looks at how certain immune cells (Treg cells) in your body relate to your muscle strength and thinking skills as you age. It may help researchers understand how to keep older adults' minds sharp.
Zhuhai, GuangdongAges 40–90 - NCT07429773Recruiting
Immune markers in stubborn pelvic pain
This study looks at the immune system's response in people with chronic pelvic pain that hasn't gotten better with first treatments. By measuring certain immune markers, the researchers hope to better understand why the pain persists and find new ways to help.

Common questions
- Are there clinical trials for immune function?
- Yes. Clin2 currently lists 48 recruiting immune function 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 function 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 function 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.
