Researchers are evaluating the efficacy and safety of elecoglipron, an oral tablet taken once daily, for weight management in adults with obesity or overweight. This Phase III global, randomized, double-blind, placebo-controlled trial includes two independent pivotal studies one in adults without type 2 diabetes T2DM and the other in adults with T2DM, all having at least one weight-related health condition. The goal is to understand how elecoglipron compares to placebo when combined with diet and exercise. Participants will be randomly assigned to receive either one of two doses of elecoglipron or a matching placebo daily. Study 1 involves about 3000 adults living with obesity or overweight without T2DM, while Study 2 involves about 1500 adults with obesity or overweight and T2DM. Both studies last 72 weeks, during which changes in body weight and other health measures will be monitored. During the trial, participants will undergo regular health assessments including measurements of body weight, waist circumference, blood sugar control, blood pressure, and other related health indicators. Researchers will track percent change in body weight from baseline at 72 weeks as the primary outcome. Participants will be monitored closely throughout the study to assess safety and effectiveness of the treatment in managing weight and associated health conditions.

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 effectiveness, safety, and tolerability of elecoglipron alone or combined with dapagliflozin compared with a placebo in adults with type 2 diabetes mellitus T2DM who are not adequately controlled by lifestyle management alone or who are on other background glucose-lowering medications. This Phase III study aims to understand how these treatments impact blood sugar control and related health factors. Participants will be randomly assigned to one of four groups elecoglipron at dose level 1 with dapagliflozin-matched placebo, elecoglipron at dose level 2 with dapagliflozin-matched placebo, a combination of elecoglipron at one of the studied doses with dapagliflozin, or matching placebos for both drugs. All treatments are taken orally once daily. The study uses a quadruple-blind design to compare these options over a treatment period lasting up to 40 weeks. During the study, participants will have their blood sugar levels measured by changes in Hemoglobin A1c HbA1c from baseline to week 40. Other assessments include body weight, blood pressure, and the time to start any additional rescue medication. Participants will attend regular visits for monitoring and safety evaluations throughout the study duration, which extends until the primary completion date in July 2028.

Researchers are evaluating the efficacy, safety, and tolerability of a study drug called elecoglipron compared with oral semaglutide in adults with Type 2 Diabetes Mellitus T2DM who have an increased risk of cardiovascular events. The study focuses on adults whose diabetes is not adequately controlled by lifestyle changes or stable treatment with other glucose-lowering medications. This is a phase III randomized trial sponsored by AstraZeneca, aiming to compare these two oral medications in managing T2DM and cardiovascular risk. Participants will be assigned to receive either elecoglipron or semaglutide, both administered orally once daily at specified doses. The study runs in parallel groups, with one group receiving elecoglipron and the other receiving semaglutide. Treatment and observation will continue for 52 weeks, during which the effects on blood sugar control and other health indicators will be evaluated. Throughout the 52-week study period, participants will undergo regular assessments including measurements of Hemoglobin A1c HbA1c, body weight, and blood pressure. Researchers will monitor changes from baseline to week 52 to understand the drugs impact on diabetes control and cardiovascular risk factors. The study also tracks safety and tolerability to ensure participant wellbeing during the trial.

Researchers are evaluating the effectiveness, safety, and tolerability of a vaccine designed to reduce Clostridioides difficile C. difficile infections in adults aged 65 years and older. This phase 3 study compares the vaccine to a placebo in a group of older adults who have recent or planned contact with healthcare systems or recent antibiotic use. The purpose is to understand how well the vaccine works to prevent infections and to monitor any side effects or reactions. Participants will receive either the C. difficile vaccine or a placebo shot injected into the upper arm muscle. The study is randomized, double-blinded, and placebo-controlled. The vaccination period includes two doses and participants will be monitored for up to about three and a half years. Follow-up includes three planned clinical visits and three phone visits initially, then yearly clinic visits until the study ends. Participants are asked to report and save stool samples if they experience three or more loose stools in 24 hours to check for possible infection. During the study, researchers will track local and systemic reactions to the vaccine within seven days after each shot, adverse events up to one month after each vaccination, and serious adverse events for up to 18 months after the last dose. The main measurement is the occurrence of medically attended primary C. difficile infections from two weeks after the second vaccination through the surveillance period. Safety monitoring and annual visits will continue until the study is completed, which could be sooner or later depending on infection rates.

Researchers are evaluating ibuzatrelvir, an oral medication, to determine its effectiveness and safety in adults and adolescents aged 12 years and older with COVID-19 who are not hospitalized but are at high risk for severe illness. The study is a phase 3, randomized, double-blind trial comparing ibuzatrelvir with a placebo. Participants must have confirmed SARS-CoV-2 infection with symptoms starting within 5 days and meet specific risk factor criteria based on age. Eligible participants will be randomly assigned to receive either ibuzatrelvir or a matching placebo twice daily by mouth for 5 days. The study allows co-administration of standard care treatments available locally. The total study duration is about 6 months, including follow-up. Participants will be monitored for emergency department visits related to COVID-19, hospitalizations, and mortality up to 28 days after starting treatment. Additional evaluations include symptom resolution, occurrence of long COVID symptoms, viral RNA levels, and safety measures such as adverse events through 24 weeks. The study involves regular assessments, including clinical visits and laboratory tests, to track outcomes and safety over time.

This research aims to learn about the safety and effects of the study medicine PF-07328948 for adults with heart failure. The study evaluates whether PF-07328948 is safe and effective compared to a placebo in people who already take standard heart failure medicines including SGLT2 inhibitors. It is a phase 2 randomized, double-blind, placebo-controlled trial sponsored by Pfizer. Participants will take either placebo tablets or one of three doses of PF-07328948 tablets once daily by mouth for 36 weeks. The study includes four groups placebo, low dose, medium dose, and high dose of PF-07328948. Treatment lasts 36 weeks, followed by monitoring and assessments. Participants will be involved for about 48 weeks with 15 visits to the study clinic, of which 5 may be performed at home by phone and 10 in person. Researchers will assess clinical events, 6-minute walk test distance, and heart failure symptom scores at baseline and week 36. Safety will be monitored through adverse event reporting up to week 40. Various questionnaires and physical tests will track health status and treatment effects throughout the study.
