A Study to Assess Change in Disease Activity and Adverse Events of Oral Upadacitinib in Adult and Adolescent Participants With Moderate to Severe Hidradenitis Suppurativa Who Have Failed Anti-TNF Therapy
Recruiting
Hidradenitis suppurativa (HS) is an inflammatory skin disease that causes painful lesions in the axilla (underarm), inguinal (groin) and anogenital (anal/genital) regions. This study will assess how safe and effective upadacitinib is in treating adult and adolescent participants with moderate to severe HS who have failed to respond to or are intolerant of anti-tumor necrosis factor (TNF) therapy. Adverse events and change in disease activity will be assessed. Upadacitinib is an approved drug fo... Read More

PV Loop & Coarctation Study
Recruiting
Coarctation of the aorta accounts for 4-7% of all congenital heart disease. While stent therapy, when feasible, is the standard of care for coarctation, it may not completely improve the work (and afterload) of the heart due to its effects on the elasticity of the aorta. This study will provide the information needed to understand the effects of current management on the cardiac mechanics and work.
