Researchers are evaluating the efficacy and safety of volrustomig compared to observation in participants with unresected locally advanced head and neck squamous cell carcinoma LA-HNSCC who have not progressed after receiving definitive concurrent chemoradiotherapy cCRT. This phase III, randomized, open-label global study aims to assess whether volrustomig can improve outcomes in this patient population. Participants are randomly assigned to one of two groups those who receive volrustomig as sequential therapy, and those who undergo observation without additional treatment. The study compares these two approaches following prior curative concurrent chemoradiotherapy. The trial includes long-term follow-up to monitor patient outcomes. During the study, participants will be regularly assessed for progression-free survival, overall survival, physical functioning, and quality of life. Researchers will also monitor for the presence of anti-drug antibodies and adverse events related to volrustomig. Follow-up evaluations may continue for up to approximately eight years to fully understand the treatment impact and safety profile.

Researchers are evaluating the combination of baxdrostat and dapagliflozin in people with chronic kidney disease CKD and high blood pressure hypertension. This Phase III, double-blind, placebo-controlled study aims to assess whether this combination reduces the risk of serious kidney damage, heart failure events, or cardiovascular death compared to dapagliflozin alone. The study includes participants with CKD and hypertension who meet specific kidney function and blood pressure criteria. Participants who are not already taking SGLT2 inhibitors will first complete a 4-week dapagliflozin run-in period. Then, they will be randomly assigned to receive either baxdrostat plus dapagliflozin or a placebo plus dapagliflozin. Baxdrostat dosing may start low and be increased if needed. Study visits will occur at 2, 4, 8, 16, 34, and 52 weeks after randomization, and then approximately every four months until the study ends, which is based on the number of key kidney or heart-related events. Throughout the study, participants will have regular assessments including blood tests to monitor kidney function and potassium levels, blood pressure measurements, and evaluations of heart and kidney health. If participants stop the blinded study drug early, they will continue dapagliflozin if possible and remain in the study for ongoing visits and monitoring. The main outcome is whether the combination treatment reduces the risk of a 50% sustained decline in kidney function, kidney failure, heart failure events, or cardiovascular death over up to 37 months.

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 and safety of Datopotamab Deruxtecan Dato-DXd with or without Durvalumab compared to investigators choice chemotherapy combined with Pembrolizumab in patients with PD-L1 positive locally recurrent inoperable or metastatic triple-negative breast cancer TNBC. This Phase III, randomized, open-label, international study aims to determine if Dato-DXd with Durvalumab can improve progression-free survival and overall survival while assessing quality of life impacts in this patient population. Participants are assigned to one of three groups Dato-DXd with Durvalumab, investigators choice chemotherapy paclitaxel, nab-paclitaxel, or gemcitabine plus carboplatin combined with Pembrolizumab, or Dato-DXd alone. All study drugs are given by intravenous infusion. The study includes stratification by geographic region, disease-free interval, and prior PD-1PD-L1 treatment. Treatment continues with monitoring up to about 33 months for progression-free survival and safety, with some outcomes followed up to 64 months. Throughout the study, participants undergo assessments including imaging to measure tumor response using RECIST criteria, laboratory tests, and questionnaires to evaluate symptoms and quality of life. Researchers monitor time to disease progression, overall survival, response duration, and safety outcomes. Follow-up includes evaluation of subsequent therapies and pharmacokinetics. The total participation duration can be up to several years to capture long-term outcomes.

Researchers are evaluating the safety, immune response, and effectiveness of the V181 dengue vaccine in healthy children aged 2 to 17 years. This study aims to see if V181 can reduce the number of dengue infections caused by any of the four dengue virus types, regardless of whether participants have had dengue before. The trial is a phase 3, randomized, double-blind, placebo-controlled study sponsored by Merck Sharp & Dohme LLC. Participants will be randomly assigned to receive a single 0.5 mL dose of either the V181 vaccine or a placebo by subcutaneous injection on Day 1. About 3600 participants are included in the Reactogenicity and Immunogenicity Subset, which will be monitored for safety and immune response for 28 days after vaccination. A smaller group of about 620 participants from this subset will be followed for up to 5 years to assess long-term immune response using specific virus neutralization tests. During the study, participants will be monitored for adverse events, vaccine reactions, and dengue infections, including severity and hospitalization rates, up to 5 years after vaccination. Safety assessments include tracking medically attended and serious adverse events. Immune responses will be measured by antibody levels and seroconversion rates. Participants will have scheduled visits during the first month postvaccination and ongoing follow-ups for several years to evaluate the vaccines long-term effects and protective benefits.

Researchers are evaluating the effect of AZD6793, an oral medication, in adults with moderate to very severe chronic obstructive pulmonary disease COPD. This Phase IIb, randomized, double-blind, placebo-controlled study involves approximately 970 participants across about 350 global sites. The trial aims to compare the efficacy and safety of two different doses of AZD6793 against placebo over a 24-week period. Participants will be randomly assigned to one of three groups receiving either dose 1 of AZD6793, dose 2 of AZD6793, or a matching placebo tablet. The study medication is taken orally and the trial lasts for 24 weeks. The study is designed as a parallel-group format with a 111 allocation ratio among the three arms. During the study, participants will be monitored through various assessments including lung function tests measuring forced expiratory volume FEV1, questionnaires evaluating breathlessness, cough, sputum, and quality of life, and tracking of COPD exacerbation events. Blood samples will be collected to measure plasma concentrations of AZD6793. Safety and efficacy outcomes will be evaluated up to 24 weeks, with the main outcome being the rate of moderate or severe COPD exacerbations.

Researchers are evaluating the efficacy and safety of tezepelumab in adults with moderate to very severe chronic obstructive pulmonary disease COPD who are receiving inhaled maintenance therapy. This Phase 3, multicenter, randomized, double-blind, placebo-controlled study focuses on adults aged 40 to 80 years who have experienced multiple COPD exacerbations in the year prior to enrollment. The trial aims to assess tezepelumabs impact compared to placebo on COPD exacerbations and lung function. Participants will receive monthly subcutaneous injections of one of two doses of tezepelumab or a matching placebo. Treatment duration ranges from a minimum of 52 weeks to a maximum of 76 weeks. Following the treatment period, participants will undergo a 12-week off-treatment safety follow-up to monitor any lasting effects. Throughout the study, participants will be regularly assessed for COPD exacerbations, lung function changes measured by forced expiratory volume FEV1, and quality of life using questionnaires such as the St. Georges Respiratory Questionnaire and COPD Assessment Test. Blood samples will be collected to measure drug levels and immune responses. Safety and efficacy will be closely monitored, with total participation lasting up to approximately 88 weeks including follow-up.

This trial is for adults who have had an acute ischemic stroke caused by a blood clot blocking a brain vessel. It focuses on people whose stroke occurred or was discovered more than 4.5 hours ago, including those who woke up with stroke symptoms. The study aims to find out if the medicine tenecteplase helps recovery when given after this 4.5-hour window, compared to standard medical care. Tenecteplase is already used within 4.5 hours after stroke onset, but this study tests its effect when given later. Participants are randomly assigned to one of two groups one receives a single injection of tenecteplase into a vein, and the other receives the usual standard treatment. Both groups have an equal chance of receiving either treatment. The study lasts about three months, starting with approximately one week of hospital stay. During the study, participants have seven clinical examinations or visits, with the final two visits conducted remotely from home to allow for easier participation. Throughout the study, doctors regularly assess participants recovery using a scale that measures disability and dependence in daily activities. They also monitor overall health and record any side effects. The main outcome measured is the level of recovery 90 days after treatment, comparing the two groups. This includes neurological improvement, bleeding events, and survival over the study period.

Researchers are evaluating whether the combination of vicadrostat BI 690517 and empagliflozin helps adults with heart failure who have symptoms and a left ventricular ejection fraction LVEF of 40% or more. This phase III study is designed to compare the effects of vicadrostatempagliflozin tablets versus placeboempagliflozin tablets on heart failure outcomes. The study aims to understand if this combined treatment improves health and reduces heart-related events. Participants are randomly assigned to one of two groups one group takes vicadrostat plus empagliflozin tablets once a day, and the other takes placebo plus empagliflozin tablets once a day. The study has no fixed duration and continues as long as participants benefit and tolerate the treatment. Throughout the study, participants visit their doctors regularly for health checks, and study staff may also contact them by phone to monitor well-being and any side effects. During the study, researchers monitor participants health through regular doctor visits and phone contacts. They collect data on heart-related events such as cardiovascular death, hospitalizations for heart failure, and urgent visits for heart failure over up to 42 months. Participants also answer questions about their symptoms and well-being. The study carefully tracks safety and treatment tolerance while gathering information to determine if the combined treatment helps people with heart failure.

Researchers are evaluating two methods of epidural analgesia for relieving labor pain Programmed Intermittent Epidural Bolus PIEB and Continuous Epidural Infusion CEI, both combined with Patient-Controlled Epidural Analgesia PCEA. This randomized controlled trial aims to compare how well each method controls pain while reducing anesthetic use and preserving maternal motor function. Sixty women in labor at Family Hospital, Da Nang, will be randomly assigned to either the PIEB or CEI group, and outcomes like pain levels, drug consumption, maternal satisfaction, and newborn Apgar scores will be assessed. All participants receive an initial manual epidural dose of 10 mL containing 0.1% Ropivacaine and 2 mcgmL Fentanyl to start analgesia. The PIEB group then receives automated 8 mL boluses every hour, while the CEI group gets a continuous infusion at 8 mL per hour. Both groups can self-administer 5 mL boluses via PCEA with a 10-minute lockout and a maximum of 20 mL per hour. If pain remains high after two PCEA demands, a 5 mL rescue bolus is given by the anesthesia team. Participants will be monitored for pain intensity at multiple time points up to 4 hours after analgesia starts and during labor stages. Researchers will also measure total anesthetic consumption, maternal motor block incidence, maternal satisfaction, and newborn Apgar scores. Monitoring continues until perineal repair is complete, with assessments up to 24 hours after enrollment. The trial is scheduled to start in July 2025 and end in August 2026.
