This study aims to evaluate whether tranexamic acid (TXA), a medication that helps reduce bleeding, can decrease fluid drainage after breast reduction surgery. Participants will be randomly assigned to receive either intravenous TXA or no TXA during surgery. Additionally, one breast will receive TXA through the surgical drain, while the other will receive saline. This approach allows to compare the effects of TXA on fluid buildup and healing. The goal is to improve recovery and reduce complications after breast reduction surgery.

This is a non-inferiority patient-centered and pragmatic comparative-effectiveness pregnancy randomized controlled trial (RCT) with postpartum maternal and child follow-up through 2 years of 1,572 individuals with gestational diabetes mellitus (GDM) randomized to oral metformin versus injectable insulin. This study will determine if metformin is not inferior to insulin in reducing adverse pregnancy outcomes, is comparably safe for exposed individuals and children, and if patient-reported factors, including facilitators of and barriers to use, differ between metformin and insulin. A total of 1,572 pregnant individuals with GDM who need pharmacotherapy will be recruited at 20 U.S. sites using consistent treatment criteria to metformin versus insulin. Participants and their children will be followed through delivery to two years postpartum.

Cephalosporin antibiotics are commonly used but can result in allergic reactions and anaphylaxis. There is no clear diagnostic approach for cephalosporin-allergic patients, and guidance for the use of other antibiotics in allergic patients is based on side chain chemical similarity and limited skin testing evidence. This project includes a clinical trial and mechanistic studies to optimize the approach to cephalosporin allergy and advance future diagnostics.

Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.

The goal of this clinical trial is to test a brief psychological intervention given to individuals in the first days following childbirth who have experienced a potentially stressful childbirth. The treatment is aimed at preventing post-traumatic stress disorder following childbirth and promoting maternal-infant bonding. In the days following childbirth, participants will be asked to write about their childbirth experience or a neutral event for three consecutive days, for around 15 minutes each day. Additionally, they will complete a short survey before and after the intervention about their birth experience and mental health. Around 2 months postpartum (with the option of up to around Month 3 PP), participants will take part in mental health and physiological assessments, and in a brief play session with their infant.

This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving pembrolizumab with radiation may kill more tumor cells than chemotherapy with radiation therapy in patients with non-muscle invasive bladder cancer.

This is a First-in-Human, Phase 1, Dose-Escalation and Dose-Expansion study of HM16390, as a single agent and in combination with pembrolizumab to assess safety, tolerability, MTD, RP2D, PK, and efficacy in patients with advanced or metastatic solid tumors. Dose-Escalation Part is planned to establish the MTD or RDs for the randomized Dose-Ranging Part. Based on the results of the Dose-Escalation Part, additional eligible subjects will be randomized 1:1 into each dose level. After a comprehensive review of available data from both Dose-Escalation Part and Dose-Ranging Part, the RDEs to be tested in the Dose-Expansion Part are determined. Dose-Expansion Part is designed to assess the potential efficacy of HM16390 as a single agent and in combination with pembrolizumab when administered at the RDEs to subjects in indication-specific expansion cohorts.

This study will evaluate how safe the study drug is, how well patients tolerate it, how it works in the body, and the disease's response to the drug. The study drug being tested is sarilumab, when given with the combination of ipilimumab, nivolumab, and relatlimab in patients like yourself, with stage III or stage IV melanoma that cannot be removed by surgery. Previous studies have provided a strong rationale for combining sarilumab, with ipilimumab, nivolumab and relatlimab in metastatic melanoma to reduce side effects and potentially work better for your type of cancer. Sarilumab is an FDA-approved inhibitor of the receptor for the cytokine IL-6, currently approved for the treatment of rheumatoid arthritis, but it is not FDA-approved to treat melanoma. This means that the use of Sarilumab to treat melanoma is considered investigational. The other drugs which will be administered in this study, ipilimumab and nivolumab, are also monoclonal antibodies, but they target different proteins. Ipilimumab and nivolumab are both approved by the FDA to treat advanced stage III and IV melanomas. The nivolumab + relatlimab FDC (fixed dose combination) being used in this study is considered investigational, meaning it is not approved by the FDA. The combination of sarilumab, ipilimumab, nivolumab and relatlimab is considered investigational because it has not yet been approved by the FDA. The FDA has given its permission to study the investigational combination of these drugs in this research study.
