Researchers are evaluating the effects of TX000045 in patients with pulmonary hypertension caused by heart failure with preserved ejection fraction (PH-HFpEF). This Phase 2, double-blind, randomized, placebo-controlled proof-of-concept study aims to assess two dosing regimens of TX000045 over a 24-week treatment period to understand its impact on pulmonary vascular resistance and safety profile. Participants will be randomly assigned to one of three groups: a placebo group receiving subcutaneous injections every two weeks, a group receiving Dose A of TX000045 subcutaneously every two weeks, and a group receiving Dose B of TX000045 subcutaneously every four weeks alternating with placebo every two weeks. The treatment period lasts for 24 weeks. Throughout the study, participants will undergo assessments including pulmonary vascular resistance measurements, physical examinations, laboratory tests, and monitoring for adverse events from baseline up to 30 weeks after the first dose. Safety evaluations focus on treatment-related side effects and changes in lab values. The study plans to enroll about 180 participants between 18 and 83 years old with specific heart and lung function criteria.

Researchers are evaluating the effects of dalcetrapib, a cholesterol ester transfer protein inhibitor, on cardiovascular risk in people who have recently been hospitalized for acute coronary syndrome (ACS) and have a specific genetic profile (AA genotype). This phase 3, placebo-controlled, randomized, double-blind study focuses on adults aged 45 years and older. Participants must be clinically stable and managed according to guidelines for low-density lipoprotein cholesterol (LDL-C). The study aims to measure the time to the first occurrence of any fatal or non-fatal myocardial infarction over an average follow-up of 30 months. Participants will be randomly assigned to receive either dalcetrapib 300 mg tablets or matching placebo tablets. The study includes a genetic screening phase to confirm the presence of the AA genotype using a specific genotype assay test. Screening and enrollment may start during hospitalization or after discharge, with randomization required within 12 weeks of the ACS event. Follow-up visits will be conducted virtually when possible every 3 months or as clinic visits until the study ends. If a participant stops the study medication early, assessments for study endpoints will continue every 3 months. Throughout the study, participants will undergo medical history reviews, genetic testing, and regular assessments to monitor cardiovascular events. Researchers will collect data on myocardial infarction occurrences as the primary outcome. Safety and adherence will be monitored through scheduled visits, and the study will continue until about 200 participants have experienced a primary event or until a planned interim analysis determines stopping. The total participation duration varies based on event occurrence but involves ongoing follow-up every 3 months after randomization.

Researchers are evaluating the effect of abelacimab compared to a placebo in patients with atrial fibrillation (AF) who are considered unsuitable for oral anticoagulation therapy. This study focuses on people at high risk for ischemic stroke or systemic embolism and aims to assess the safety and effectiveness of abelacimab in preventing these events. The study is a Phase 3, multicenter, randomized, double-blind, placebo-controlled trial involving patients with AF who have specific risk factors and treatment challenges. Participants will receive either abelacimab, provided as a liquid in vials at 150 mg/mL, or a matching placebo liquid. The study design includes parallel groups with blinded treatment assignment. The trial does not describe additional treatment phases or extensions but focuses on the comparison of abelacimab and placebo over the study duration. During the study, participants will be monitored for up to 30 months to measure the time until the first occurrence of ischemic stroke or systemic embolism, as well as the time until the first occurrence of serious bleeding as defined by the Bleeding Academic Research Consortium (BARC) type 3c/5 bleeding. Safety and efficacy will be closely evaluated, with ongoing assessments to track these outcomes throughout the follow-up period.

Researchers are evaluating whether the drug zilebesiran can reduce the risk of major cardiovascular events such as cardiovascular death, nonfatal heart attacks, strokes, or heart failure in adults who have hypertension that is not well controlled and who either have established cardiovascular disease or are at high risk for it. This Phase 3 global study is designed to continue until enough cardiovascular events have occurred to assess the treatment's effect. Participants will be randomly assigned to receive either zilebesiran or a placebo, both given as injections under the skin (subcutaneous administration). All participants will continue with their standard care, which includes treatment with at least two antihypertensive medications, one of which must be a diuretic such as a thiazide or loop diuretic. The study is double-blind, so neither participants nor researchers know who is receiving the active drug or placebo. During the study, participants will be closely monitored for cardiovascular events including heart attacks, strokes, heart failure hospitalizations, and cardiovascular deaths over approximately five years. Researchers will collect data on these events to determine the time until the first occurrence of any of these outcomes. Safety assessments and standard clinical evaluations will also be performed throughout the study period to ensure participant well-being.
