This study tests whether omega-3 fatty acid supplements from fish oil, combined with a healthy diet, can reduce disease activity in adults with dermatomyositis, a rare autoimmune disease causing muscle weakness and skin rashes. About 300 participants will take either fish oil cap…

This study tests a drug called H01 (hymecromone) in adults with interstitial lung disease, a condition that causes lung scarring and makes breathing hard. The goal is to see if H01 can lower a marker of lung damage and improve lung function. Participants take the drug as a tablet…

This study looks at how your genes and your environment—like what you eat, breathe, and experience—work together to influence common diseases such as diabetes, heart disease, and asthma. Researchers are collecting health questionnaires, genetic data, and other information from 25…

This study aims to learn more about myositis, a group of diseases that cause muscle inflammation and damage. Researchers will observe up to 1,200 children and adults with myositis, along with healthy volunteers, to track changes in the immune system and other health problems over…

This study aims to understand how reproductive disorders, such as delayed or early puberty, are inherited. Researchers will collect blood samples and medical histories from 850 people with these conditions and their family members. No treatment is provided; the goal is to identif…

This study follows 400 adults aged 18–60 with moderate-to-severe asthma for up to 5 years. Researchers collect blood, urine, stool, dust, saliva, and lung samples at regular visits to see how bacteria and other environmental factors affect asthma symptoms and flare-ups. The goal …

This study looks at how certain white blood cells (neutrophils and monocytes) sense signals in the body and what substances they release, especially when they might cause inflammation. Healthy adults aged 18 to 65 who weigh at least 110 pounds can join by donating blood up to six…

This study investigates whether certain environmental exposures—like infections, stress, or sun exposure—are more common in people with anti-synthetase syndrome, a rare autoimmune condition that causes muscle weakness and lung disease. Researchers will compare 580 participants, i…

This study looks at how the body's innate immune system responds to certain environmental exposures by measuring inflammation markers in blood. Researchers will collect blood samples from up to 725 healthy volunteers aged 18-45 to analyze how specific genes and proteins react. Th…

This study collects blood and urine from 2,000 healthy adults aged 18 and older to build a repository for future laboratory research. Participants provide samples during a single 2-hour visit. The goal is to help scientists develop better tests and improve sample handling methods…

This study looks at whether overweight girls start puberty earlier than girls of normal weight. Researchers will use breast ultrasound and other tests to tell the difference between breast tissue and fatty tissue. The study involves 150 healthy girls ages 8-14 who have some breas…

This study follows healthy girls ages 8-14 and teens with irregular periods to learn how their menstrual cycles become regular after their first period. Researchers also include girls at risk for PCOS and compare them to women with and without PCOS. The goal is to understand norm…

This study aims to understand the long-term mental, physical, and social impacts of COVID-19 on minority women and their families in North Carolina. About 700 healthy women aged 18 and older who are African American, Hispanic, Native American, Asian American, or Pacific Islander …

This study aims to understand how environmental factors like pollution, diet, and stress contribute to human disease. Researchers will collect samples such as blood, urine, and skin from 2,000 healthy adults aged 18 and older. Participants may also complete surveys and provide ho…

This study looks at how things in your environment—like pollution, chemicals, diet, and sleep—might affect your hormones and reproductive health. Researchers will follow 300 people aged 8 and older who have conditions like low or high hormone levels, early or late puberty, or inf…
