This study is for people who have had a lung transplant and developed a condition called chronic lung allograft dysfunction (CLAD), which is a type of chronic rejection. Doctors often treat CLAD with a procedure called extracorporeal photopheresis (ECP), but it can take up to six months to know if the treatment is working. The goal of the study is to find early signs (biomarkers) that show whether ECP is helping, so patients can get the right care sooner. For participants in the study, small blood samples will be collected at three points during ECP treatment and, for some participants, two MRI scans of the lungs will be performed-one before starting ECP and one after finishing treatment. The MRI uses a safe contrast dye to help us see changes in lung blood flow and tissue. Investigators will also look at certain immune cells in the blood. This is not a study of a new drug or treatment-participants will receive the same ECP therapy their doctor already recommended. The study will help researchers understand how ECP works and identify markers that predict who benefits most. There is no direct benefit to participants, but participation may help improve care for future lung transplant patients.

Estrogen-dominant gender-affirming hormone therapy (GAHT) is standard of care for transgender women and gender-diverse individuals and typically consists of estrogen together with anti-androgen/ testosterone therapy. Estrogen and testosterone balance influences fat and muscle mass, muscular strength and the development of sarcopenia. Sarcopenia, a condition characterized by the loss of muscular mass, strength, and function, in turn, is associated with increased mortality and adverse health outcomes. Estrogen-dominant GAHT may have deleterious effects on body composition and muscular performance that place TGD individuals at-risk for sarcopenia. As part of NCT04128488, our investigative team found that appendicular lean mass (ALM)/ height2 decreases after estrogen-based GAHT, thereby portending a higher risk for sarcopenia after GAHT. Early recognition of the changes in body composition and muscular performance leading to sarcopenia are critical, providing potential avenues to intervene and abrogate untoward downstream health effects. A promising intervention is resistance exercise, which has been shown in select populations to improve muscular mass and strength and reduce fat mass, and, thus, mitigate progression to sarcopenia in at-risk populations. For this prospective, pilot clinical trial, investigators will enroll participants who are about to be initiated on estrogen-dominant gender-affirming hormone therapy. Investigators will be randomizing participants 1:1 to either an at-home resistance exercise intervention or no exercise intervention (nutritional and exercise counseling only) for 12 weeks and assess muscle mass, strength, and function both before and after this 12-week period. The exercise intervention group will be provided with the necessary materials to complete the exercise program along with weekly virtual visits with our study team in order to learn their assigned exercises for the week. Further, survey tools will be administered to ascertain whether the resistance exercise intervention may affect gender congruence.

Phase 2b Study of RPT904 as Monotherapy in Participants With IgE-Mediated Food Allergy: This is a Phase 2b randomized, double-blind, placebo-controlled clinical trial evaluating RPT904, a next-generation anti-IgE monoclonal antibody, in people with food allergy. RPT904 is a long-acting antibody that may allow for dosing every 8 to 12 weeks. Approximately 100 participants between the ages of 12 and 55 with documented allergy to at least one of the following foods: peanut, milk, egg, cashew, or walnut will be enrolled. In Part 1 (24 weeks), participants will be randomly assigned to receive RPT904 every 8 or 12 weeks (plus a loading dose at Week 2), or placebo. In Part 2 (24 weeks), participants who received RPT904 will continue on their assigned dosing schedule, and those who previously received placebo will be re-randomized to receive RPT904 either every 8 or 12 weeks (plus a loading dose at Week 26). All participants will attend study visits approximately every 2-6 weeks throughout both Part 1 and Part 2 to maintain blinding, regardless of treatment group or dosing frequency. The study is being conducted at multiple sites. The primary goal is to assess whether RPT904 helps participants tolerate higher amounts of a food allergen without dose-limiting allergic symptoms during a food challenge. The study will also monitor the safety and side effects of RPT904 over time. Each participant is expected to be in the study for about 68 to 74 weeks, including screening, treatment, and follow-up.

The goal of this clinical trial is to learn if therapy with activin ligand-trap biological therapy (an investigational drug) combined with exercise training can improve exercise capacity and cognitive function in heart failure with preserved ejection fraction (HFpEF). The main questions it aims to answer are: - Does activin-ligand trap biological therapy improve exercise capacity as measured by change in peak oxygen uptake (peak VO2) from baseline to week 12? - Does activin-ligand trap biological therapy improve cognitive function as assessed by the NIH-Toolbox Cognition Battery (NIHTB-CB) composite score and Rey Auditory Verbal Learning Test (RAVLT) from baseline to week 12? Researchers will compare activin-ligand trap biological therapy to a placebo (a look-alike substance that contains no drug) to see if activin-ligand trap therapy works to improve exercise capacity and cognitive function in patients with HFpEF.

The Comprehensive HHT Outcomes Registry of the United States (CHORUS) is an observational registry of patients diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). The purpose of this study is to better understand HHT, the symptoms and complications it causes, and the impact the disease has on people's lives. The investigators will collect long-term information about the participant, allowing us to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease. Another important goal of the study is to provide a way to contact people to participate in future clinical trials and other research. The registry will be a centralized resource for recruitment for clinical trials. People in the registry will not be obligated to join any of these additional studies, but if interested, can agree to be contacted if they may be eligible for a study. Participants will: - Be asked to provide permission to collect information from their medical records, including things like demographic information, diagnosis information, family history, test results, treatment information, symptoms, complications, lifestyle and other relevant medical information. - Be asked study-related questions by phone or at a clinic visit. - Be asked study-related questions every year after enrollment for up to 10 years or until the study ends. A member of the study team will communicate with participants by phone or at clinic visits to collect information regarding any changes to their health over the previous year/s including new test results, treatment information, symptoms, and complications from HHT.
