This study is designed to characterize the safety, tolerability, and anti-tumor activity of MDX2001 in patients with advanced solid tumors.

Type: Interventional

Start Date: Jun 2024

open study

This clinical trial is studying solid tumor cancers. A solid tumor is one that starts in part of your body like your lungs or liver instead of your blood. Once they've grown bigger in one spot or spread to other parts of the body, they're harder to treat. This is called advanced or metastatic cancer. Participants in this study must have breast cancer or gastric cancer. Participants must have tumors that have HER2 on them. This allows the cancer to grow more quickly or spread faster. There are few treatment options for patients with advanced or metastatic solid tumors that express HER2. This clinical trial uses an experimental drug called disitamab vedotin (DV). Disitamab vedotin is a type of antibody drug conjugate or ADC. ADCs are designed to stick to cancer cells and kill them. This clinical trial uses a drug called tucatinib, which has been approved to treat cancer in the United States and some other countries. This drug is sold under the brand name TUKYSA®. This study will test how safe and how well DV with tucatinib works for participants with solid tumors. This study will also test what side effects happen when participants take these drugs. A side effect is anything a drug does to the body besides treating the disease.

The main purpose of this study is to: - Learn about the safety of ubamatamab and to find out what dose of ubamatamab can be given alone or with cemiplimab to patients with ovarian cancer or cancer of the uterus - The study will also look at the levels of ubamatamab and/or cemiplimab in the body and measure how well the body can remove the study drug(s). This is called pharmacokinetics - The study will also look at any signs that ubamatamab alone or with cemiplimab can treat recurrent advanced ovarian cancer or cancer of the uterus - To find out how safe and tolerable pretreatment is in combination with ubamatamab and to see how well it works to prevent or minimize Cytokine Release Syndrome (CRS)

The goal of this observational study is to learn about the natural progression of Angelman syndrome (AS) in children and adults with a confirmed genetic diagnosis of AS. The main questions it aims to answer are: - How do developmental skills, such as communication, motor abilities, and adaptive behaviors, change over a 1-year period in people with AS? - Are there specific patterns in brain activity or sleep that are associated with changes in AS symptoms over time? Participants will: - Visit the study site 5 times over 1 year (approximately every 3 months) for assessments. - Complete tests and questionnaires about development, behaviors, and sleep with the help of their caregivers. - Undergo electroencephalograms (EEGs) to measure brain activity and wear a sleep-monitoring device at home (to collect actigraphy data).

This is a multi-center, randomized, open label study that will assess the efficacy and safety of ACTEMRA(R) or one of its FDA-approved biosimilars Tocilizumab (TCZ) maintenance versus withdrawal in Giant cell arteritis (GCA) patients who are in remission after at least 12 months of high dose TCZ treatment. Eligible participants will also have discontinued glucocorticoids (e.g., prednisone (or equivalent)) entirely at least three months before randomization. High dose TCZ treatment includes 6-8 mg/kg intravenously (IV) monthly or 162 mg subcutaneously (SC) weekly, which are two forms of administration that are commonly used in clinical practice and are equally efficacious in controlling GCA This research study has three parts: 1. The screening phase (up to 42 days) consists of collecting information about your health and your GCA, a physical exam, and blood tests to see If you qualify to enroll in the study 2. The study treatment phase (withdrawal/step down dosing phase study months 0 - 18) consists of you either completely stopping or decreasing your current dose of tocilizumab while collecting information about your health and your GCA as well as blood samples every two months at clinic visits 3. The safety follow-up phase (months 19-30) consists of collecting information about your health and your GCA as well as blood samples every three months The primary objective is to determine the rate of disease relapse at 18 months in participants with GCA who receive low-dose TCZ compared to those who discontinue TCZ

The hypertensive disorders of pregnancy (preeclampsia and gestational hypertension) are associated with increased long-term maternal risk of developing cardiovascular disease. Recent evidence suggests that activation of the mineralocorticoid receptor promotes ongoing susceptibility to hypertension in women following hypertensive disorders of pregnancy. In addition, women with overweight/obesity are at increased risk for progression to chronic hypertension after experiencing hypertensive disorders of pregnancy. Among women with hypertensive disorders of pregnancy and pre-pregnancy overweight/obesity, the investigators will conduct a randomized trial to test the effect of pharmacologically blocking the mineralocorticoid receptor for three months after delivery on blood pressure and cardiac remodeling at nine months postpartum.

This study is structured around three main aims. In Aim 1, investigators will conduct community-based participatory research (CBPR) to develop culturally tailored methods to assess childhood adversity in multiple sclerosis (MS). Aim 2 will investigate the impact of childhood adversity on MS outcomes among individuals with relapsing-remitting MS (RRMS), among whom 70% belong to a group historically under-represented in MS research: Black, Hispanic, or poverty-impacted. Aim 2 procedures involve two visits that include a research blood draw and an MRI scan. In Aim 3, investigators will conduct interviews and surveys to explore environmental and social factors affecting quality of life for minority MS patients.
