Allergic Diseases and Eczema (Atopic Dermatitis)

Online Survey About Eczema

This 10- to 20-minute survey is available for patients with eczema or parents of patients with eczema.  These questions will help us learn more about patient experiences to improve current research and guide future research. 

Arthritis

Rheumatoid Arthritis Studies

NIAID is committed to advancing the understanding of how and why autoimmune diseases such as rheumatoid arthritis occur.

Asthma

Preventing Asthma in High Risk Kids (PARK)

This trial is a randomized, double-blind, placebo controlled trial designed to test whether two years treatment of preschool children aged 2-3 years of age at high risk for asthma with omalizumab (anti-IgE) for two years will prevent the progression to childhood asthma, as reflected by a reduction in the prevalence of active asthma in the Final 12 months during 2 year observation period off study drug.

Sorting and Expression Profiling of Airway Cells From Humans (The SEARCH Study) (SEARCH)

This will be a single site, mechanistic study of asthmatic subjects and healthy, non-asthmatic controls involving a baseline characterization visit and a research bronchoscopy visit.

Study of the Inflammation and Airway Changes That Occur After Exposure to Allergen in Asthmatics (ACE)

This protocol describes a single site mechanistic study to investigate microRNAs (miRNAs) that are differentially expressed in the airway epithelium of patients with asthma at baseline and in response to allergen challenge.

Chronic Granulomatous Disease (CGD)

Patients Treated for Chronic Granulomatous Disease (CGD) Since 1995

This study will determine the long term medical condition and daily functioning of participants with CGD after a transplant and if possible, compare these results to participants who do not undergo a transplant.

Study of Gene Therapy Using a Lentiviral Vector to Treat X-linked Chronic Granulomatous Disease

This study is a prospective non-controlled, non-randomized Phase I/II clinical trial to assess the safety, feasibility and efficacy of cellular gene therapy in patients with chronic granulomatous disease.

Coronaviruses

Big Effect Trial (BET) for Finding Promising Treatments of COVID-19

The primary purpose of NIAID's ACTIV-5/BET study is to evaluate the efficacy of  investigational therapeutics in adults hospitalized for COVID-19.

Diabetes

TrialNet Pathway to Prevention of Type 1 Diabetes

The goal of this study is to enhance understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes.

Type 1 Diabetes Extension Study (T1DES)

The goal of this study is to further the understanding of the immunologic mechanisms underlying maintenance and loss of beta cell function by evaluating the relationship between longitudinal changes in beta cell function and changes over time in biomarkers known to be associated with a response to immune modulating treatments used in prior clinical trials.

Eczema (Atopic Dermatitis)

Effect of Dupilumab on the Host-Microbe Interface in Atopic Dermatitis

Research teams across the United States are conducting this clinical trial to assess the effect of dupilumab in treating the skin of adults with chronic moderate to severe atopic dermatitis or eczema.

Targeted Microbiome Transplant in Atopic Dermatitis

The purpose of this study is to examine the safety and effectiveness of a new therapy, commensal lotion containing infection-fighting bacteria, on decreasing or eliminating the infection-causing bacteria found on the skin of atopic dermatitis patients.

Flu (Influenza)

Evaluating the Safety and Efficacy of Anti-Influenza Intravenous Hyperimmune Immunoglobulin (IVIG) in Adults Hospitalized With Influenza

The purpose of this study is to evaluate whether IVIG can reduce the severity and duration of flu in people who are hospitalized with the flu.

Respiratory Virus Hospitalization Study (FLU 003 Plus)

The purpose of this observational study is to describe the characteristics and outcomes over a 60-day follow-up period of participants with influenza virus infection (including influenza A subtypes such as H3N2 and 2009 H1N1, or influenza B), or a targeted non-influenza respiratory virus, who are hospitalized with severe illness and/or complication in geographically diverse locations.

Food Allergy

Six Food vs. One Food Eosinophilic Esophagitis Diet Study (SOFEED)

The purpose of this interventional study is to test and compare the effectiveness of two elimination diets—the 1-food elimination diet (1FED, milk only) and the 6-food elimination diet (6FED, milk, egg, wheat, soy, tree nut/peanuts, and fish/shellfish). The study will also test the effectiveness of swallowed glucocorticoid therapy in some of the study participants for whom diet therapy was not effective.

Hepatitis

Monitoring SOF/VEL in Treatment Naïve, HCV Participants With Active Infection (MINMON)

This study is trying to see whether taking an HCV treatment with fewer clinic visits and laboratory tests can cure just as many people as the standard approach that uses more visits and laboratory tests.

HIV/AIDS

Help End HIV - Red Ribbon Registry

HIV remains a major health issue globally and within the United States. Recent audience research found that many Americans are not aware that HIV is still a health issue in the U.S., are unsure if they might be vulnerable to exposure, and do not know if there is a cure.

Safety and Efficacy Study of Injectable Cabotegravir Compared to Daily Oral Tenofovir Disoproxil Fumarate/Emtricitabine (TDF/FTC), For Pre-Exposure Prophylaxis in HIV-Uninfected Cisgender Men and Transgender Women Who Have Sex With Men

This study will evaluate the safety and efficacy of the injectable drug cabotegravir (CAB LA), for pre-exposure prophylaxis (PrEP) in HIV-uninfected cisgender men and transgender women who have sex with men (MSM and TGW).

Immunologic Diseases

An Open-Label Trial of Losartan Potassium in Participants With Eosinophilic Esophagitis (EoE)

The purpose of this study is to test the safety and effectiveness of Losartan potassium in subjects with Eosinophilic Esophagitis (EoE), both those with a connective tissue disorder (CTD) and those without a CTD.

OMEGA Outcome Measures in Eosinophilic Gastrointestinal Disorders Across the Ages (OMEGA)

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms to see if scores on standard questionnaires can give us an idea how well the person is doing.

Lupus

Clinical Research Studies of Systemic Lupus Erythematosus

Lupus is an autoimmune disease characterized by inflammation of different tissues of the body. The most common type of lupus is systemic lupus erythematosus (SLE). Women are at far greater risk than men of developing lupus, and SLE disproportionately affects minority populations.

Lyme Disease (Borreliosis)

Human Immune Response to Ixodes Scapularis Tick Bites

The aim of this study is to learn how peoples’ bodies, particularly the skin, respond to tick bites.
