Researchers are evaluating two different pacing methods for patients with slow heart rates, called bradycardia. This study compares the common right ventricular pacing approach with a newer physiological pacing method that includes His bundle and left bundle area pacing. The trial aims to better understand how these pacing techniques affect patient outcomes, including mortality and heart failure morbidity, in a large group of 2600 patients. Participants will receive a pacemaker implant and be randomly assigned to either right ventricular pacing or physiological pacing. The physiological pacing may involve His bundle pacing or left bundle pacing, but if these are not successful, biventricular pacing will be used. A subgroup of 500 participants will take part in an optional echocardiographic sub-study to assess heart function changes over a 24-month period. Throughout the study, patients will be assessed at baseline and every six months after randomization, with follow-up lasting up to 78 months. Researchers will monitor outcomes such as mortality, heart failure events, device-related safety issues, patient quality of life, symptoms, and pacemaker-derived data like arrhythmias and activity levels. The echocardiographic sub-study will measure specific heart function changes to understand pacing-induced cardiomyopathy. Participants involvement includes implantation, regular follow-up visits, questionnaires, and optional imaging assessments.

Researchers are evaluating whether less frequent dosing of pembrolizumab after six months of standard treatment is safe and effective for patients with advanced non-small cell lung cancer NSCLC. Pembrolizumab, an immunotherapy targeting the PD-1 receptor, has improved outcomes in NSCLC, but current dosing every six weeks for up to two years may result in overtreatment. This UK phase III trial aims to find if reducing dose frequency can maintain effectiveness while improving quality of life and lowering costs. Participants who have received six months of pembrolizumab, with or without chemotherapy, and plan to continue treatment will be randomized to receive pembrolizumab intravenously every six weeks control or every twelve weeks initially. If the 12-week dosing is found to be not less effective, additional groups receiving doses every nine, fifteen, and eighteen weeks will be included. Patients who experience disease progression while on reduced frequency dosing can return to the standard six-week schedule. Throughout the study, participants will be monitored for overall survival at 18 months from randomization, along with other outcomes such as progression-free survival, response rate, duration of response, and adverse events over two years. The study involves regular hospital visits for treatment and assessments, and the results may lead to safer, more convenient treatment options for NSCLC patients. The total participation time varies depending on individual treatment and follow-up schedules.

Researchers are comparing the effectiveness of two different combinations of immunotherapy drugs with chemotherapy for adults with stage IV or recurrent non-squamous non-small cell lung cancer that has PD-L1 expression of 1% or higher. This phase 3, randomized study focuses on participants who have not previously received systemic treatment for advanced disease. The goal is to determine which combination better improves overall survival and other outcomes in this patient group. Participants will be randomly assigned to receive either Nivolumab plus Relatlimab combined with chemotherapy or Pembrolizumab combined with chemotherapy. The chemotherapy drugs used include Carboplatin, Pemetrexed, or Cisplatin, given in specified doses on scheduled days. Treatment is given as first-line therapy for their cancer, with dosing details managed throughout the study period. During the study, participants will undergo imaging scans like CT or MRI to measure disease status, and blood tests to monitor safety and side effects. The main outcome measured is overall survival over up to five years, along with progression-free survival, response rates, duration of response, and adverse events. Researchers will also assess symptoms related to lung cancer over two years. Participants are monitored regularly to track these outcomes and ensure safety throughout the study duration, which may last several years.

Researchers are evaluating the effectiveness of icotrokinra JNJ-77242113 compared to a placebo in adults with active psoriatic arthritis PsA, including those who have and have not previously used biologic treatments. The study aims to assess how well icotrokinra reduces the signs and symptoms of PsA, focusing on improvements measured by the American College of Rheumatology ACR 20 response at Week 16. Participants are randomly assigned to receive one of two doses of icotrokinra or a matching placebo. Those initially receiving placebo will switch to one of the icotrokinra doses at Week 16. Participants who continue without discontinuing the study drug are eligible to enter a long-term extension phase, where they keep receiving their assigned icotrokinra dose. The treatment period involves regular monitoring and assessment of psoriatic arthritis symptoms. Throughout the study, participants will undergo various assessments, including evaluations of joint swelling and tenderness, skin psoriasis severity, fatigue, physical function, and quality of life. Laboratory tests such as C-reactive protein levels will be measured to monitor inflammation. Researchers will track responses using validated scales like the Psoriatic Area and Severity Index PASI and Investigator Global Assessment IGA. The total duration includes treatment and follow-up visits up to Week 16, with options for extended treatment in the long-term extension phase.

Researchers are evaluating whether skipping additional axillary treatment for patients with early-stage breast cancer who had cancer in their lymph nodes before chemotherapy but show no remaining cancer in those nodes after treatment is as effective as the standard approach. This study focuses on disease-free survival and reducing the risk of lymphoedema five years after treatment. It is a randomized, open, multicenter trial including patients with specific breast cancer stages and confirmed nodal metastases. Participants will all receive standard therapies including HER2-targeted treatment, endocrine therapy, and radiotherapy to the breast or chest wall if needed. They will be randomly assigned to one of two groups one group will not get further axillary treatment such as lymph node removal or radiotherapy, while the other group will receive these axillary treatments according to local guidelines. Follow-up visits will occur annually for at least five years. During the study, participants will undergo assessments to monitor disease-free survival and self-reported lymphoedema using specific questionnaires. Additional evaluations include arm function, quality of life, recurrence rates, survival, and cost-effectiveness analyses. The total study duration is planned for 120 months, including setup, recruitment, follow-up, analysis, and reporting.

Researchers are conducting Enroll-HD, a large, ongoing observational study that combines and expands previous Huntingtons disease HD registries across multiple continents, including Europe, North America, Australasia, and Latin America. This study collects longitudinal clinical data and biological samples from individuals with manifest HD, those carrying or at risk of carrying the HD gene mutation, and control participants without the mutation. The goal is to build a rich database to support research into disease progression, prognosis, and developing clinical trial endpoints. Participants include those with diagnosed HD, pre-manifest carriers, relatives with unknown or negative genotype status, family controls, and community controls. The study involves annual assessments with no planned end date, allowing for long-term data collection. Researchers collect demographic, clinical, family history, genetic, and blood sample information systematically from over 150 sites worldwide. During the study, participants undergo motor, functional, behavioral, and cognitive assessments using standardized tools such as the Unified Huntingtons Disease Rating Scale and Problem Behaviors Assessment-Short. Data are updated at each visit, including clinical signs and genotyping results. The study database is periodically made available to researchers globally, and participants may contribute for many years, helping to advance understanding and support future interventional studies in HD.

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.

Researchers are studying patients with newly diagnosed stage I, II, and III colorectal cancer CRC to understand how circulating tumor DNA ctDNA in the blood can predict disease relapse. The study evaluates whether using ctDNA to guide adjuvant chemotherapy decisions after surgery is as effective as standard chemotherapy, aiming to reduce unnecessary treatments and side effects. This multi-center, prospective research includes both observational and randomized components to better manage early-stage CRC. The study has two parts Part B focuses on collecting tumor tissue, serial blood samples, and clinical data to detect minimal residual disease MRD using ctDNA after curative surgery. Part C is a randomized trial comparing ctDNA-guided adjuvant chemotherapy versus standard care in patients with high-risk stage II or III CRC. Patients are randomized post-surgery to either standard chemotherapy or a ctDNA-guided approach where those testing negative for ctDNA may receive less chemotherapy. Participants will undergo regular blood sampling and clinical assessments to monitor ctDNA levels and disease status. Researchers will measure outcomes such as 3-year disease-free survival and the relationship between ctDNA detection and treatment response over several years. The study includes follow-up periods of 4 to 8 years to evaluate long-term outcomes and safety. Participants need to consent, adhere to follow-up schedules, and be suitable for chemotherapy if randomized to Part C.
