Researchers are conducting a multi-center clinical study to assess artificial intelligence AI algorithms for measuring heart function and size using echocardiography. The study aims to compare AI measurements with those of physicians at different experience levels, evaluate the accuracy and stability of AI, and explore its use in complex heart conditions like cardiomyopathy, valve disease, and coronary heart disease. The goal is to improve diagnostic consistency and clinical workflows across medical centers. The study involves measuring cardiac chamber size and function in 1600 participants using AI, senior physicians, and intermediate physicians. All measurements are made with Mindray ultrasonic machines. AI and intermediate physician results are completed within one day after data collection, while senior physician results are completed within one month. The study will establish a standardized reference system for AI-assisted echocardiographic measurements and evaluate AIs performance in special cases. Participants will undergo echocardiographic scans with measurements of left and right ventricular size and function, Doppler ultrasound indicators, and valve annulus displacements. Researchers will analyze data to compare AI and physician measurements, assess measurement deviations, and evaluate AIs efficiency in reducing analysis time. The study will run until July 2026, with ongoing data collection and analysis across multiple centers, aiming to promote wider clinical application of AI technology for cardiovascular disease diagnosis.

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 safety and effectiveness of tezepelumab in adults aged 40 to 80 years with moderate to very severe chronic obstructive pulmonary disease COPD. This phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on participants already receiving inhaled maintenance therapy and who have experienced multiple COPD exacerbations in the previous year. The trial aims to understand tezepelumabs impact on reducing COPD flare-ups and improving lung function compared to placebo. Participants are randomly assigned to receive monthly subcutaneous injections of one of two doses of tezepelumab or a matching placebo. The treatment period lasts between 52 and 76 weeks, followed by a 12-week safety monitoring period without treatment. Throughout the study, participants continue their inhaled COPD therapies, and their health is closely tracked to assess the study drugs effects. During the trial, participants will undergo various assessments including lung function tests, questionnaires measuring respiratory symptoms and quality of life, and blood tests to monitor drug levels and immune responses. Researchers will measure the annual rate of moderate or severe COPD exacerbations and other health outcomes over the study period. Safety will be monitored throughout treatment and during the follow-up period, with visits scheduled regularly to collect data and support participant care.

Researchers are investigating the effects of amlodipine alone versus amlodipine combined with folic acid in Chinese adults aged 45 to 74 years who have H-type hypertension, specific MTHFR 677 genotypes CC or CT, elevated plasma homocysteine levels, and low serum folate. This large, multi-center, randomized, double-blind, double-dummy clinical trial aims to evaluate which treatment better reduces the risk of first ischemic stroke over five years. Participants are first screened and then enter a 2 to 4 week run-in period where they take amlodipine to assess tolerance and compliance. Afterward, eligible participants are randomized by genotype into two groups one receiving amlodipine 5mg daily with a placebo, and the other receiving amlodipine 5mg combined with 0.8mg folic acid daily with a placebo. Other blood pressure medications may be added as needed to reach target blood pressure goals. Follow-up visits occur every three months during the five-year treatment period with medication provided at each visit. Throughout the study, participants undergo interviews, clinical evaluations, and laboratory tests including genetic and blood analyses. Researchers monitor adherence, blood pressure, and cardiovascular health. The main outcome measured is the occurrence of first ischemic stroke by the end of five years. Secondary outcomes include other cardiovascular events and kidney function. Two interim analyses will be conducted during the study to assess progress and safety.

Researchers are evaluating the effects of different amlodipine-based treatments on the risk of first ischemic stroke in Chinese adults aged 45 to 74 years with hypertension and the MTHFR 677 TT genotype. This large, multi-center, randomized, double-blind, triple-dummy controlled trial aims to compare amlodipine alone, amlodipine combined with folic acid, and amlodipine combined with folic acid plus 5-methyltetrahydrofolate over a 5-year period. The study focuses on preventing ischemic stroke as the primary outcome. Participants first undergo a screening period to confirm eligibility through interviews, clinical evaluations, and lab tests. Those who qualify enter a 2 to 4 week run-in phase with daily amlodipine to check treatment tolerance and compliance. Eligible participants are then randomly assigned to one of three daily oral treatment groups amlodipine alone, amlodipine folic acid, or amlodipine folic acid plus 5-MTHF. Additional antihypertensive medications may be added as needed to control blood pressure. Participants are followed every 3 months for drug distribution and monitoring. Throughout the study, participants will have regular clinical visits, interviews, and biological sample collections to monitor health and treatment effects. Researchers will track the incidence of first ischemic stroke and other cardiovascular and kidney outcomes over five years. Safety and treatment adherence are carefully observed, with two planned interim analyses during the trial. Total participation spans from initial screening through five years of treatment and follow-up.

Researchers are conducting a phase II clinical trial to evaluate the safety and effectiveness of RC1416 injection in adults aged 40 to 85 with moderate to severe chronic obstructive pulmonary disease COPD. The study is randomized, double-blind, and placebo-controlled, aiming to better understand treatment options for patients with this lung condition. The trial is sponsored by Nanjing RegeneCore Biotech Co., Ltd. Participants will receive either the RC1416 drug or a placebo through subcutaneous injections every two weeks for a year. The study focuses on two doses of RC1416 and compares them against placebo to assess impacts on COPD exacerbations and lung function. Treatment continues for 52 weeks under close medical supervision. Throughout the study, participants will undergo regular assessments including lung function tests such as forced expiratory volume in 1 second FEV1, and measurements of biomarkers like FeNO, total IgE, eosinophil count, and TARC levels. Safety, tolerability, pharmacokinetics, and immunogenicity will also be monitored. The trials total duration for treatment and evaluation is one year, with careful tracking of participants health and response to the study drug.

Researchers are evaluating pulsatile electrical impedance tomography EIT as a noninvasive, bedside, radiation-free method to diagnose and monitor acute pulmonary embolism, a serious type of venous thromboembolism. The study includes both retrospective and prospective phases to compare EIT parameters with CT pulmonary angiography and clinical indicators. This observational research aims to assess whether EIT can aid in diagnosis, risk stratification, and dynamic treatment monitoring for patients with pulmonary embolism. The study uses pulsatile EIT to measure ventilation-perfusion matching index, dead-space ventilation index, and intrapulmonary shunt index. In the retrospective phase, existing clinical and EIT data from patients confirmed with pulmonary embolism and healthy controls are collected and compared. The prospective phase enrolls newly diagnosed patients and healthy volunteers, performing EIT examinations alongside routine clinical evaluations and follow-up. Serial EIT measurements may track changes during treatment and recovery. No study treatments are assigned clinical care follows standard practice. Participants will undergo EIT examinations and routine clinical assessments including CT pulmonary angiography, D-dimer tests, and echocardiography. Researchers will measure diagnostic accuracy of EIT parameters and their correlation with embolic burden, thrombus location, clinical risk, and patient outcomes. Dynamic changes in EIT readings during treatment and follow-up will also be evaluated. The study spans multiple centers and involves healthy volunteers, with participation lasting through initial diagnosis and follow-up periods as determined by clinical care.

Researchers are evaluating the safety and effectiveness of TQC2731 injection in adults with severe asthma that is not well controlled. This is a Phase III clinical trial where 660 participants with asthma are randomly assigned to receive either TQC2731 or a placebo. The study aims to see if TQC2731 can reduce asthma worsening episodes over one year compared to placebo. Participants receive either the TQC2731 injection or placebo every four weeks for up to 48 weeks through subcutaneous injection. The treatment cycles repeat monthly from the start until Week 48. The study compares these two groups to assess the impact on asthma symptoms and lung function. Throughout the trial, participants will have regular assessments including lung function tests, asthma symptom diaries, quality of life questionnaires, and blood tests for inflammation markers and immune response. Researchers track the number of asthma exacerbations during the 52 weeks of treatment and up to 64 weeks for some outcomes. Safety and immune reactions are monitored carefully. The total study duration for each participant is about one year of treatment plus follow-up.
