Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study. This trial focuses on patients with established atherosclerotic cardiovascular disease ASCVD or those at high risk for a first ASCVD event. The study aims to assess how AZD0780 compares to placebo in reducing the risk of major adverse cardiovascular events, also known as MACE-PLUS, over the course of the trial. Participants are randomly assigned to receive either oral AZD0780 once daily or a matching placebo once daily. The study continues until a primary analysis censoring date, which may be up to approximately 54 months from randomization. After this, a study closure visit will be conducted as the final visit for each participant. During the study, participants will be regularly monitored for cardiovascular events including heart attacks, strokes, urgent coronary revascularizations, and other related outcomes. Researchers will track the time to first occurrence of these events as the primary outcome. Safety and other secondary outcomes like all-cause mortality will also be assessed. The total participation time can last up to about 54 months, with ongoing evaluations throughout this period.

Researchers are evaluating the safety of an investigational varicella vaccine VNS Vaccine compared to an approved varicella vaccine called Varivax. This study focuses on healthy children aged 12 to 15 months who have not had chickenpox or received any varicella vaccine before. The goal is to understand how well the new vaccine is tolerated in this young population. Participants will receive one dose of either the investigational varicella vaccine or the marketed Varivax vaccine, both given by injection under the skin. Along with the varicella vaccine, each child will also receive one dose each of measles, mumps, and rubella MMR vaccine, hepatitis A vaccine, and a pneumococcal conjugate vaccine PCV, which may be PCV 13, Vaxneuvance, or PCV 20, depending on availability and national recommendations. All vaccines are given on the first day of the study. During the study, parents will record any side effects their child experiences, particularly those related to the injection site or systemic symptoms like fever, for up to 43 days. Researchers will monitor any adverse events, including serious and medically attended events, for up to 181 days after vaccination. This helps assess the safety and tolerability of the investigational vaccine over a period of about six months.

Researchers are evaluating the adaptation and implementation of an innovative clinical decision support CDS tool called ePNa, originally validated in emergency departments, for use in urgent care clinics to improve pneumonia diagnosis and treatment. This study aims to combine ePNa with Stanfords CheXED artificial intelligence model to classify chest images quickly and accurately. The goal is to enhance pneumonia care in ambulatory settings where high patient volumes may benefit from updated and efficient diagnostic tools, especially as COVID-19 evolves. The study involves adapting ePNa for use in urgent care clinics by modifying it to work with the more limited patient data available in these settings and incorporating a chest imaging prompt. The combined ePNa-CheXED tool will be piloted among super user clinicians during clinic shifts. One of two clusters of urgent care clinics will receive the adapted tool, while the other will serve as usual care control. Additionally, a physician survey will assess clinicians experiences with ePNa-CheXED six months after implementation. Participants will be patients aged 12 and older diagnosed with pneumonia, confirmed by radiographic imaging. Physicians and advanced practice clinicians in selected urgent care clinics will also participate by completing surveys. The study will monitor outcomes including the accuracy of pneumonia diagnosis, changes in transfer rates to emergency departments, unplanned subsequent ED visits or hospitalizations, and overall healthcare resource use. The study will continue for up to three years, with ongoing evaluation of ePNa use and impact in the urgent care clinical environment.

Researchers are evaluating the efficacy and safety of tozorakimab delivered under the skin in adults with uncontrolled asthma who are already using medium-to-high doses of inhaled corticosteroids. This phase IIb, double-blind, placebo-controlled study aims to find the optimal dosing range of tozorakimab in this population. The study is sponsored by AstraZeneca and uses a randomized, parallel design to compare different doses and placebo. Participants will receive subcutaneous injections of either tozorakimab at one of two dose levels or a placebo. The study arms include dosing with tozorakimab Dose 1, tozorakimab Dose 2, or placebo, administered under the skin. The treatment period lasts from 26 to 52 weeks, during which participants will be monitored for their asthma symptoms and lung function. Throughout the study, participants will undergo assessments including lung function tests such as forced expiratory volume in 1 second FEV1, asthma control questionnaires ACQ-6, quality of life questionnaires AQLQ12, and measurements of asthma exacerbations. Blood samples will be collected to measure drug levels and immune response. Safety and adherence will be closely monitored, and the primary outcome is the annualized rate of severe asthma exacerbations over the treatment period.

Researchers are examining the effect of abelacimab compared to a placebo in patients with atrial fibrillation AF who are considered unsuitable for oral anticoagulation therapy. This Phase 3 study focuses on high-risk patients with AF to evaluate whether abelacimab can reduce the occurrence of ischemic stroke or systemic embolism. The study is led by Anthos Therapeutics, Inc. and aims to address treatment options in patients where traditional anticoagulation is deemed inappropriate. Participants are randomly assigned in equal numbers to receive either abelacimab 150 mg or a matching placebo by subcutaneous injection once a month. The study consists of three periods a screening period lasting up to 60 days, a double-blind treatment period that continues until at least 111 patients experience a primary endpoint event, and an end-of-treatment visit. Following this, participants may enter a 30-day follow-up or an optional open-label extension to receive abelacimab, depending on eligibility and regulatory approval. During the study, participants undergo assessments to monitor stroke, systemic embolism, and bleeding events, with the primary outcomes measured up to 30 months. Safety is tracked by recording bleeding events classified by the Bleeding Academic Research Consortium. Secondary outcomes include cardiovascular and all-cause mortality and other thrombotic events. The study also involves regular monitoring and follow-up visits to assess efficacy and safety throughout the treatment and observation periods.
