NCT03304678
Background: Lymphangioleiomyomatosis (LAM) is a rare, progressive disease. It usually affects women in the prime of their lives. It typically results in lung destruction. Studies have shown that a drug called sirolimus stabilizes lung function in people with LAM. But researchers do not know what drug dose and blood serum levels are needed to reach this stability. Researchers want to learn more about the right dose of sirolimus for people with LAM. Objective: To determine if blood and urine markers after 1 dose and again after 9 months can be used to evaluate the correct dose of sirolimus for people with LAM. Eligibility: Women ages 18-90 with LAM whose doctors have decided they should start taking sirolimus to treat it. Design: At visit 1, participants will take their first dose of sirolimus by mouth at the clinic. They will have blood and urine collected. Participants will take 1 tablet of the study drug each day. Visit 2 will be 3 months after visit 1. Participants will have blood and urine collected. Visit 3 will be 9 months after visit 1. Participants will have blood and urine collected. Participant samples will be stored in a secure place. No personal data will be connected to them.
NCT06455787
The primary objective of this study is to assess the safety and efficacy of the J-Valve Transfemoral (TF) System in patients with symptomatic, severe (grade 3 or 4), native aortic valve regurgitation (AR) and AR-dominant mixed aortic valve disease, who are judged by a multi-disciplinary heart team to be at high risk for open surgical aortic valve replacement (SAVR). A Cardiac Magnetic Resonance (CMR) sub-study will examine if intervention for AR translates to improved ventricular remodeling, the impact of LV remodeling on clinical outcomes and quality of life, as well as volumetric and myocardial differences between genders.
