The purpose of this research study is to study the utility of advanced blood testing for patients who have had a stroke and tend to form blood clots more than usual. The study involves blood tests using a new testing system that may detect issues with blood clotting easier than conventional tests. This is a 12-month study and will involve one blood draw and follow-up phone calls

This research is being done to better understand how anti-cancer drugs affect cells within a tumor. Injecting very small amounts (microdoses) of pembrolizumab alone or in combination with MK-0482 or MK-4830 above may help the developer of these drugs to understand more about how these drugs work and what changes they make on the tumor. Subjects in this study will have their tumor injected with anti-cancer drugs using a CIVO device. The CIVO device delivers microdoses of multiple drugs or drug combinations directly into the tumor. Some of the procedures in this study include ultrasound assisted placement for tumor injection, a mucrodose injection of anti-cancer drugs into the tumor, and surgery to remove the tumor. Participation in the study will take 5 visits over a period if 56 days. The screening portion will be 28 days and the treatment portion will be 28 days from the time of the injection to the time of follow-up contact by the study team.

Pimavanserin is an antipsychotic may have some beneficial effects on core autism symptoms and co-morbid conditions such as irritability, anxiety, sleep disorders, mood instability due to epilepsy, etc.). These potential benefits stem from pimavanserin's impact on the serotonin system in the body. This study will investigate pimavanserin in the treatment of irritability, core autism symptoms, and co-morbid conditions in children ages 6-17 years old.

The study is for patients who have been diagnosed with non-squamous non-small cell lung cancer (NSCLC). The investigational drug in this study is ivonescimab (AK112). The study drug is an antibody, it blocks two proteins in the body that help cancer cells live, grow and spread. The study drug will be given in addition to pemetrexed and carboplatin. There are two groups that a participant may be assigned to, which group a subject is assigned on will be determined by type of cancer treatments that they have previously received. Treatment Group A will receive the study drug along with pemetrexed and carboplatin. Treatment Group B will receive placebo along with pemetrexed and carboplatin. The drugs will be given via an infusion. There is a 50% chance of being assigned to either group. Participation in the study will last about 36 months. The study consist of a screening visit, treatment visits, and a safety follow up visit.

This study is part of what is called a platform study. This platform study, called the "PRACTICAL" study is designed so that various interventions can be evaluated at the same time against standard therapy. This allows researchers to compare these newer interventions to each other as well as to the established usual practice and helps them explore different ways to potentially improve the management of lung injury. Within the platform study there are various different sub-studies that have their own interventions and procedures. This domain sub-study is the "Mechanical Ventilation Study" and it is a multi-centre, randomized, open-label trial that will evaluate multiple ventilation strategies in comparison to conventional lung-protective ventilation in patients with acute hypoxemic respiratory failure (AHRF). This domain will enroll perpetually, as interventions are added, continued, or discontinued. Researchers for this study are looking for different types of ventilation strategies (ways that the ventilators control settings can be adjusted) that may be the most helpful for people in their recovery, while also reducing lung damage caused by the ventilator.

This is a phase 4, prospective, multicenter, single-arm, open-label study designed
to evaluate the effect of early and rapid treprostinil therapy on mean pulmonary artery pressure (mPAP) reduction to improve Right ventricular (RV) function and reverse RV remodeling in patients with PAH. This study will use the CardioMEMS™ HF System (CardioMEMS) to measure and monitor mPAP, but may allow mPAP monitoring via RHC (right heart catheterization), if CardioMEMS is NOT available at a subject's Baseline Visit (Day 1) or if the CardioMEMS™ PA Sensor implantation is unsuccessful.

Participation is expected to be up to 37 months and will include about 10 office visits to the study doctor. This will be divided up into a 30-day Screening Period, a 12-month Treatment Period, and a 24-month Extended Treatment Period.

The purpose of this study is to assess the feasibility and safety of modified surgical eyeglasses to view bevonescein intraoperatively and the safety of bevonescein as it shows nerve tissue in the body. Bevonescein is an investigational drug being developed to help doctors identify nerves within the body during surgery.
The drug is administered through a vein in the arm and into the blood stream.t Bevonescein then travels through the blood where it makes nerve tissue fluorescent so that it can then be detected by the modified surgical eyeglasses used in this study by a surgeon. This may help the surgeon (study doctor) to tell the difference between nerve tissue and other tissue during surgery. Bevonescein and the modified surgical eyeglasses that your surgeon will wear (ReVealTM 475) are considered investigational because they are not approved by the Food and Drug Administration (FDA) to help with the visualization of nerves during surgery Alternatives to this study can include to undergo surgery without the study drug.

The duration of this study is about 2 months. The procedures of this study include administration of the study drug once (500 mg), collection of blood and urine samples, and ECGs. Surgery will happened as planned by the study doctor but as part of the research, the surgeon will ear modified surgical eyeglasses to view nerves and may take pictures or video clips. The glasses are FDA cleared but the modified filter and its use in combination with bevonescein is considered experimental.

The most commonly expected risks of fluorescein are nausea, vomiting, and stomach discomfort. Because bevonescein is cleared through the urine, there may be a potential risk to the kidneys and renal (kidney) system. The most serious risks of fluorescein may include severe local tissue damage, anaphylaxis, convulsions, cardiac arrest, and death.

The purpose of this study is to learn about the effects of an experimental treatment called RO7198457. This study is for patients with Stage II or III colon or rectal cancer, which has been treated surgically and with chemotherapy, and your blood has been found to have ctDNA (circulating tumor DNA) during a ctDNA screening test. RO7198457 (autogene cevumeran) is an immunotherapy that is individualized to a tumor and designed to mount an immune response against it. Treatment includes RO7198457 being injected in the vein, physical exams, blood sample collections, and CT scans for up to a year. Risks include fatigue, fever, and headache. Patients may or may not receive direct benefit while on the study, however, information collected during this study will help people with colon and rectal cancer in the future. RO7198457 is considered "experimental" because it has not been approved by the U.S. Food & Drug Administration (FDA) for the treatment of any disease.

This study is enrolling subjects who are scheduled for a ventricular tachycardia (VT) ablation. Ventricular tachycardia is a fast heartbeat that starts with an abnormal signal in the lower chambers of the heart, which are the ventricles. An ablation is a procedure where a catheter (thin, flexible tube) with a tip that can deliver energy is used to burn the heart tissue where those abnormal signals are coming from. The catheter being used in this study is called the FlexAbilityTM Ablation Catheter and was recently approved for commercial use by the Food and Drug Administration. (FDA) Since it is newly approved, the FDA wants to continue collecting more information about the catheter and its use, so this study is called a post approval study. Participation in this study will take about 1 year. During this year, data will be collected including your medical history, cardiac medication use, ablation procedure, and any medical events that may occur. You will be seen or contacted 4 times. There is a risk of loss of confidentiality and there may be risks that are not yet known. There may be no direct benefit to you but it is hoped the information learned may contribute to knowledge in this field.

The protocol aims to improve standard of care, by ensuring an agile research infrastructure, with an ability to rapidly assess interventions during epidemic transmission of one or more respiratory pathogens adversely affecting public health.

Trials within this protocol can be adaptive, will be randomized, and will have superiority as the primary objective. Comparisons in the trials may be between an unlicensed agent to a blinded placebo plus standard of care (SOC), between an approved off-label agent to a blinded placebo plus SOC, among several active interventions (blinded or non-blinded; i.e., a comparative effectiveness study), or among different treatment strategies.
