- NCT03914664Enrolling by invitation
Brain and sensation study in adults with Tourette syndrome
This study looks at brain activity and how sensory experiences feel in adults with Tourette syndrome. It compares you to carefully matched adults without neurologic or psychiatric conditions to understand what is different in the brain.
Nashville, TennesseeAges 18 years+ - NCT03856229Enrolling by invitation
Short steroid treatment for lung infection from PCP in HIV
This study tests whether short-term steroid treatment helps adults with a specific lung infection (PCP) that happens with HIV/AIDS. It compares outcomes in people who start steroids soon after admission while also taking standard PCP antibiotics.
México, State of MexicoAges 18–80 - NCT03815279Enrolling by invitationPhase 2
Trial for active or high-risk smoldering myeloma treatments
This Phase 2 study tests a treatment approach for adults with active multiple myeloma (MM) or a high/intermediate-risk “smoldering” MM that hasn’t been treated yet. It may help by trying to control the disease earlier or more effectively, depending on what the trial drug(s) do.
ReykjavikAges 18 years+ - NCT03755245Enrolling by invitation
Imaging study using a tracer to measure inflammation in joints and lungs
This trial tests how a radioactive imaging medicine (a tracer called 68Ga-DOTA-Siglec-9) spreads in the body and how well it shows inflammation. It includes both healthy volunteers and people with active rheumatoid arthritis, vasculitis, or pulmonary sarcoidosis to see if the scan matches disease activity.
TurkuAges 18–70 - NCT03727399Enrolling by invitation
Testing blood for grass or birch allergy antibodies
This study looks at your blood to find allergy-related antibodies if you have pollen allergies to grass or birch. It may help researchers better understand what in the immune system drives allergy symptoms.
Zurich, Canton of ZurichAges 18 years+ - NCT03713229Enrolling by invitation
Seville study of people with HIV at risk for anal cancer
This study follows people living with HIV who may be at higher risk for anal cancer. It aims to better understand risk and outcomes, which could help guide future screening or prevention.
SevilleAges 18 years+ - NCT03628612Enrolling by invitationPhase 2
Long-term follow-up after CAR T cell treatment
This study checks how people do over the long run after receiving a personalized, genetically modified CAR T cell treatment. It may help researchers understand long-term safety and outcomes, which can improve future care.
Miami, FloridaAges 1 year+ - NCT03576573Enrolling by invitation
Follow-up study for specific hip replacement components
This study checks outcomes after a specific type of hip surgery using specific brand parts. You may help by sharing follow-up visit information so the sponsor can confirm the components work as expected in everyday patients.
BuxtehudeAges 21 years+ - NCT03478670Enrolling by invitation
Registry follow-up for ADA-SCID patients treated with Strimvelis
This study keeps track of people with ADA-SCID (a rare immune system condition) who previously received Strimvelis or a related treatment. It helps doctors understand long-term outcomes and safety after treatment.
Milan, LombardyAges Any age - NCT03429426Enrolling by invitation
Tracking joint bone damage in rheumatoid arthritis with scans
This study uses high-resolution scans and regular X-rays to see how bone erosions (bone wear) progress in people with rheumatoid arthritis over time. It may help researchers better understand disease changes and how to measure them.
AarhusAges 18 years+ - NCT03369353Enrolling by invitation
Personalized immune testing study for bowel and transplant patients
This study looks at whether a precise lab test can help understand inflammatory bowel disease, functional gut disorders, and immune changes after stem cell transplant or cell therapy. It may help doctors choose better monitoring and treatments based on your immune and gut test results.
Boston, MassachusettsAges Any age - NCT03291756Enrolling by invitation
CorEvitas Multiple Sclerosis registry for people starting MS medicine
This registry collects health information from adults with multiple sclerosis (MS) when they start an MS medicine. It may help researchers better understand treatment patterns and outcomes in real-world care.
Waltham, MassachusettsAges 18 years+ - NCT03032601Enrolling by invitation
N-acetyl cysteine study for people with multiple sclerosis
This study tests whether N-acetyl cysteine (a supplement-like medicine) changes body and brain function in people with multiple sclerosis. It may help researchers understand how it affects brain chemistry and activity using special brain imaging.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02974647RecruitingPhase 2
Ruxolitinib for relapsed or hard-to-treat T/NK cell lymphoma
This trial studies ruxolitinib, a medicine that affects immune signaling, in people whose T-cell or NK-cell lymphoma has returned or hasn’t responded to treatment. It may help shrink lymphoma and improve symptoms after other therapies.
Miami, FloridaAges 18 years+
Common questions
- How many immune system & allergy clinical trials are recruiting?
- Clin2 is tracking 6,230 recruiting immunology & allergy studies from the U.S. registry right now, out of 9,786 we cover in this area in total.
- What does “Immune system & allergy” cover here?
- Autoimmune conditions, allergies, and disorders of the body’s immune defenses. We group each study into immune system & allergy based on the conditions it studies, so you can scan the whole therapeutic area at once and drill into a specific condition.
- How do I find a immune system & allergy trial near me?
- Use the search to filter immune system & allergy studies by location and eligibility. Every Clin2 trial page explains the criteria in plain English and offers a short, optional pre-screen for a fit read — the study team makes the final decision.
