Nivolumab for advanced cancer with autoimmune disease
This trial tests whether the immunotherapy drug nivolumab can safely treat advanced cancer in people who also have an autoimmune disease like rheumatoid arthritis, lupus, or multiple sclerosis. It aims to find out if the drug may help control cancer while managing their autoimmune condition.
Birmingham, AlabamaAges 18 years+ - NCT03723928Recruiting
Blood test–guided monitoring for metastatic breast cancer treatment
This study checks whether specific blood “tumor marker” levels can help monitor how hormone receptor–positive, HER2-negative metastatic breast cancer responds to first-line therapy. It uses regular blood tests (and sometimes scans) to see if this marker-based monitoring is useful and reliable.
Anchorage, AlaskaAges 18 years+ - NCT03678194Recruiting
Smartphone app tool for doctors managing daily depression
This trial tests a smartphone app that helps doctors manage depression in everyday life. It may help improve how care is tracked and adjusted soon after starting antidepressant treatment.
BordeauxAges 18–65 - NCT03713203Recruiting
Light-based treatment for vulvar Paget’s disease
This study tests a special light treatment (photodynamic therapy) for non-invasive Paget’s disease on the vulva that has come back after surgery. It may help by treating remaining abnormal skin cells where surgery may not remove everything.
LilleAges 18 years+ - NCT03510442Recruiting
Study of genetics and causes of systemic juvenile arthritis and Still's disease
This study aims to learn more about the causes and genetics of two related inflammatory conditions: systemic juvenile idiopathic arthritis (sJIA) in children and adult-onset Still's disease (AOSD) in adults. By studying patients and healthy volunteers, researchers hope to understand these diseases better and find better ways to treat them.
Bethesda, MarylandAges 1 day–100 years - NCT03374215Recruiting
Study hormone causes of high blood pressure in Black adults
This study looks at the body’s hormone signals to understand what causes primary aldosteronism (a condition that can lead to high blood pressure). By comparing clinical results and lab data, researchers hope to improve how the condition is diagnosed and managed, especially in Black participants.
