Calgary, AlbertaAges birth+ - NCT04864886Recruiting
Study how immune-related conditions affect metabolism
This study collects blood and other samples to see how the immune system changes “metabolism” (how your body uses energy) in people with immune-related conditions. Your samples may also be stored for future research and could help researchers better understand immune health.
Bethesda, MarylandAges 18–75 - NCT04885959Enrolling by invitation
Study how an Asian diet affects gut bacteria and allergy risk in pregnancy
This study looks at whether eating a traditional Asian diet during pregnancy changes gut bacteria and body chemistry in a way that may lower (or change) a baby’s risk of developing allergies. You would follow the diet during pregnancy and be tracked after delivery.
Kota Bharu, KelantanAges 18–40 - NCT04772170Recruiting
Study wearable and symptom monitoring during respiratory virus challenges
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
Bethesda, MarylandAges 18–65 - NCT04751760Recruiting
Test a new blood test for IgE allergy markers
This study checks whether a new blood test can measure allergy-related immune signals (IgE) in people with known or suspected allergies. If it works well, it could help doctors diagnose and track IgE allergies more easily.
ToulouseAges 6 months–99 years - NCT04582903Recruiting
Send-in sample collection study for immune response to respiratory viruses
This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.
Rockville, MarylandAges 1 day–99 years - NCT04438525Recruiting
BAT test to replace sting challenge in venom allergy care
This study looks at whether a BAT (a blood test) can stand in for sting/venom “challenges” for people already receiving venom immunotherapy. If it works, it could help patients avoid more risky or uncomfortable challenge procedures while still checking whether treatment is working.
GrazAges 18–70 - NCT04259359Recruiting
Bee sting allergy trial for people starting venom immunotherapy
This trial studies whether having strong reactions to a specific bee venom protein can make venom immunotherapy less effective. It may help doctors better predict who is at higher risk for therapy failure after bee stings.
GrazAges 18–70 - NCT04367883Recruiting
Study of flu shots and blood-pressure medicines in COVID
This study looks at people who were admitted to the hospital in Terrassa starting in March 2020. Researchers want to see whether having a flu vaccine and using certain blood-pressure medicines (ACE inhibitors or ARBs) is linked to how COVID infection develops.
Terrassa, BarcelonaAges Any age - NCT04097561RecruitingPhase 1
Belimumab safety study for low CD4 counts and autoantibodies
This Phase 1 study tests how safe belimumab is for people with idiopathic CD4 lymphopenia (low protective white blood cells) and signs of autoantibodies. It aims to learn whether the treatment is tolerable and could be a future option for people with this immune condition.
Bethesda, MarylandAges 18–70 - NCT04047628RecruitingPhase 3
MS patients with active relapsing disease comparing two treatment plans
This Phase 3 study compares the best standard MS treatment (chosen by your doctors) versus an approach called autologous hematopoietic stem cell transplant (AHSCT) for people with highly active, treatment-resistant relapsing multiple sclerosis. It aims to see which option controls MS disease activity better and keeps you safer over time.
Palo Alto, CaliforniaAges 18–55 - NCT04052022Recruiting
Study of TB flare-ups in people without HIV
This study looks at why some people with tuberculosis (TB) get worse or develop new inflammation after they initially start improving on treatment—called a “paradoxical reaction.” It collects blood and tissue samples to better understand these flare-ups and guide future care.
Bethesda, MarylandAges 18–99 - NCT04034264Recruiting
Fever Study in Cambodia Using New DNA Testing
This study is looking at people in Cambodia who have a fever or have been in close contact with someone who has a certain infection. Researchers will use a new type of DNA test to try to find the cause of the fever.
Chbar MonAges 2 months+ - NCT03949855RecruitingPhase 2
Belimumab plus rituximab for primary membranous nephropathy
This study tests whether adding belimumab to rituximab helps people with primary membranous nephropathy (a kidney disease) that has the right blood test marker and specific protein levels. The goal is to improve kidney outcomes and reduce disease activity while keeping treatment safe.
Birmingham, AlabamaAges 18–75 - NCT03937817Recruiting
Donate samples to study globin gene variants
This study collects common body samples to learn how different globin gene variants work and how they relate to health. Your samples may also be used later for new research, including genetic testing.
Bethesda, MarylandAges 18–70 - NCT03878121RecruitingPhase 1
Ad4-HIV vaccine study for healthy adults and partners
This Phase 1 study tests whether an experimental HIV vaccine (made from a harmless viral vector) is safe and helps the body build immune defenses. It includes healthy volunteers and, in some groups, their close partners, with careful screening and follow-up visits.
Bethesda, MarylandAges 18–65 - 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+ - NCT03538600Recruiting
Sample collection from healthy volunteers to improve test accuracy
This study collects multiple types of samples (like blood, stool, saliva, and swabs) from healthy people. The goal is to optimize lab tests for future research, which may help doctors and scientists run more accurate immune-related measurements.
