PIONEER-ALS is a Phase 1/2, multicenter, open-label, ascending dose, uncontrolled, first-in-human study that will evaluate the safety, tolerability and effects on clinical and biomarker endpoints of intracisternal administration of Vtx-002 in participants with Amyotrophic Lateral Sclerosis (ALS). Two escalating dose (low dose and high dose) cohorts are planned. The duration of the study will be a maximum of 5 years and 5 weeks (265 weeks) for each participant. The screening period may last up to 5 weeks to complete screening procedures.

This is a study of LY4337713 in participants with certain types of cancer that is advanced or has spread. Participants must have cancer with high levels of a protein called fibroblast activation protein (FAP). The purpose of this study is to evaluate safety, side effects, and efficacy of LY4337713. In addition, this study will evaluate how much LY4337713 gets into the bloodstream, how it is broken down, and how long it takes the body to get rid of it. For each participant, the study will last about 5 years.

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 goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).

The main objective of this study is to evaluate the efficacy of satralizumab compared with placebo based on time from randomization to the first occurrence of an adjudicated MOGAD relapse in the double-blind (DB) treatment period. Participants who experience an adjudicated relapse or complete the DB period can enter open-label extension (OLE) period. After the primary clinical cutoff date (CCOD), additional adolescent participants may be enrolled directly into the OLE period.

There are few treatment options available for patients once they have failed standard psychopharmacological therapy for generalized anxiety disorder. Existing brain stimulation methods such as rTMS fail to target deep brain structures associated with anxiety disorders; structures such as the amygdala. In this double-blind sham-controlled clinical trial, the investigators propose to establish baseline severity of anxiety in 48 patients, then deliver eight treatments over four sessions of focused ultrasound stimulation to the amygdala. Anxiety severity will be assessed using standard psychometric scales after each session, and at follow-ups.

The Fabry Registry is an ongoing, international multi-center, strictly observational program that tracks the routine clinical outcomes for patients with Fabry disease, irrespective of treatment status. No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician. The primary objectives of the Registry are: - To enhance the understanding of the variability, progression, and natural history of Fabry disease, including heterozygous females with the disease; - To assist the Fabry medical community with the development of recommendations for monitoring patients and reports on patient outcomes to help optimize patient care; - To characterize and describe the Fabry population as a whole; - To evaluate the long-term safety and effectiveness of Fabrazyme® Fabry Pregnancy Sub-registry: This Sub-registry is a multicenter, international, longitudinal, observational, and voluntary program designed to track pregnancy outcomes for any pregnant woman enrolled in the Fabry Registry, regardless of whether she is receiving disease-specific therapy (such as enzyme replacement therapy with agalsidase beta) and irrespective of the commercial product with which she may be treated. Data from the Sub-registry are also used to fulfill various global regulatory requirements, to support product development/reimbursement, and for other research and non-research-related purposes. No experimental intervention is given; thus a patient will undergo clinical assessments and receive standard of care treatment as determined by the patient's physician. If a patient consents to this Sub-registry, information about the patient's medical and obstetric history, pregnancy, and birth will be collected, and, if a patient consents to data collection for her infant, data on infant growth through month 36 postpartum will be collected.

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.
