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 the combination of CGT9486 and sunitinib compared to sunitinib alone in patients with locally advanced, unresectable, or metastatic Gastrointestinal Stromal Tumors GIST. This Phase 3, open-label international trial involves multiple parts, including dose confirmation, drug interaction assessments, and efficacy comparisons. The study also includes substudies focusing on drug-drug interaction potential and first-line treatment in patients with specific genetic mutations KIT exon 9. Approximately 482 patients will participate across these parts.

Researchers are observing pregnant women whose unborn babies have been diagnosed with Congenital Diaphragmatic Hernia CDH. They aim to use medical images from routine care to create detailed 3D animations and models of the fetus and its CDH. This helps parents understand the condition and assists surgeons in planning the babys surgery after birth. The study involves no additional interventions instead, it uses images that mothers would normally receive as part of their prenatal care. The focus is on developing 3D visualizations from fetal MRI scans to better assess the size of the diaphragmatic hole and the position of organs. Participants will be pregnant women referred for fetal MRI at a specialized fetal medicine unit. Researchers will collect patient demographics and use routine imaging data to create these models. There is no treatment given, and participation involves allowing access to the MRI images taken during normal prenatal care. The study is expected to continue until June 2027.

Researchers are working to create and use a comprehensive database focused on intracranial aneurysms IA. This project collects and studies clinical history, imaging data, biological samples, and other information to understand factors linked to the formation and rupture of aneurysms. They aim to identify genetic, environmental, and anatomical markers, as well as evaluate outcomes from different treatment strategies and improve patient care protocols. Participants include patients with diagnosed aneurysms, both ruptured and unruptured, family members of affected individuals, and healthy volunteers. Data collected involves detailed clinical records, imaging scans like MRI angiography and CT angiography, and various biological samples such as blood, cerebrospinal fluid, saliva, and stool. Consent covers access to medical records, use of biological samples, and potential future research uses including genetic analyses. During the study, participants provide health and lifestyle information, imaging data, and biological samples. Researchers will monitor multiple long-term outcomes including disease progression, life expectancy, quality of life, neurological and cognitive status, and treatment effects over periods up to 20 years. Data confidentiality is maintained, and participants can withdraw at any time without affecting their medical care. The study aims to validate disease models and support advances in aneurysm management and research.

Researchers are studying pulmonary arterial hypertension PAH, a condition where lung blood vessels become thick and narrow, causing high blood pressure in the lungs and making it hard for the heart to work. PAH can cause difficulty breathing and limit activity. While standard treatments help symptoms, they do not stop the disease from worsening. This research focuses on sotatercept, a targeted therapy aimed at specific proteins involved in PAH, to learn about its long-term safety and tolerability when added to usual PAH treatments. Participants in this long-term follow-up study, who previously took part in certain sotatercept trials, may continue receiving sotatercept by subcutaneous injection every three weeks. Those coming from blinded studies start at 0.3 mgkg with possible increases up to 0.7 mgkg, while those from unblinded studies continue their current dose with possible titration to 0.7 mgkg. The study monitors participants over an extended period to assess continued effects alongside their usual PAH therapy. During the study, participants will have regular assessments including monitoring for adverse events, blood tests for blood components and chemistry, body weight, blood pressure, and ECG readings. Researchers will also evaluate exercise capacity, heart function markers, and risk scores related to PAH. The study aims to follow participants for up to approximately 7 to 8 years to understand long-term safety, treatment tolerability, and health changes while using sotatercept with standard PAH care.

Researchers are evaluating the dose-response relationship of galvokimig compared with placebo in adults with moderate-to-severe atopic dermatitis AtD. The study focuses on participants who have had chronic AtD for at least one year and aims to assess how different doses of galvokimig impact the condition. This phase 2 trial is designed to better understand the drugs effects on symptoms and safety in this population. Participants are randomly assigned to one of several groups receiving different predefined doses of galvokimig or a matching placebo during an initial 16-week intervention period. After week 16, participants continue treatment with the same or a modified dose of galvokimig. The study uses a double-blind design to compare the effects of these doses on atopic dermatitis. During the study, participants will undergo regular assessments including the Eczema Area and Severity Index EASI, Investigator Global Assessment vIGA, and Peak Pruritus Numerical Rating Scale PP-NRS. Safety is monitored through reported adverse events up to week 58. The primary outcome is the percentage of participants achieving a significant improvement in EASI score at week 16. The total study duration extends beyond 16 weeks to include ongoing safety and response evaluations.

Researchers are evaluating zorevunersen, an investigational antisense oligonucleotide drug, in children with Dravet syndrome, a rare and severe form of epilepsy. This Phase 3, global, multicenter, randomized, double-blind, sham-controlled study aims to assess the efficacy, safety, and tolerability of zorevunersen by measuring changes in major motor seizure frequency and other important aspects such as behavior, cognition, clinical status, and quality of life. Participants will be randomly assigned to receive either zorevunersen or a sham procedure during Treatment Period 1, which lasts about 52 weeks. Zorevunersen is given by intrathecal injection at specific doses and intervals throughout this period. After Treatment Period 1, all eligible patients enter Treatment Period 2, where everyone receives zorevunersen for additional dosing over several months. Patients who complete the study may have the chance to join an open-label extension to continue receiving the drug. During the study, participants will undergo regular assessments including seizure monitoring, behavioral and cognitive evaluations, and health-related quality of life measurements. The primary outcome is the change in major motor seizure frequency at Week 28, with secondary outcomes assessed at Week 52. Safety and tolerability are also closely monitored. Overall participation lasts through both treatment periods and possible extension, with detailed follow-up to evaluate the drugs potential for disease modification.

Researchers are evaluating the safety of LY3954068 in people with early symptomatic Alzheimers Disease. This study also examines how much of the drug enters the bloodstream and its effects on Alzheimers markers. It is a Phase 1 trial sponsored by Eli Lilly and Company focused on participants aged 50 to 85 years with early signs of the disease. The study includes two parts Part A and Part B. In Part A, each participant receives a single dose of LY3954068 or placebo injected into the spinal fluid. In Part B, participants receive two doses of either LY3954068 or placebo administered the same way. There is an optional bridging period after Part B where participants may receive LY3954068 in a separate study. Part A lasts about 45 weeks including screening, and Part B lasts about 100 weeks including screening. Participants will undergo regular assessments such as safety monitoring for adverse events related to the study drug, blood and spinal fluid sampling to measure drug levels and effects on tau proteins, and imaging with Flortaucipir F18 PET scans for tau pathology. Cognitive tests like the Mini Mental State Examination and Clinical Dementia Rating will be used. Safety and drug effects will be followed up to 24 weeks in Part A and up to 52 weeks in Part B, with additional monitoring during the bridging period if chosen.

Researchers are evaluating the long-term safety of subcutaneous guselkumab injections in children with moderately to severely active ulcerative colitis, Crohns disease, or juvenile psoriatic arthritis. This Phase 3 study focuses on pediatric participants who have previously been treated with guselkumab and will continue therapy in this extension study to monitor safety over an extended period. Participants who completed dosing in one of three primary pediatric guselkumab studies and are deemed by their investigator to benefit from continued treatment will join this long-term extension. Guselkumab is administered as a subcutaneous injection either every 8 weeks or every 4 weeks, depending on prior study assignment and clinical status. Some participants may switch dosing frequency once during the extension before unblinding, after which dosing aligns with their original regimen. Dose adjustments are restricted based on the primary study they came from. During the study, participants will receive guselkumab injections regularly and be monitored for treatment-emergent adverse events for up to nearly seven years. Researchers will assess safety outcomes through ongoing clinical evaluations over this time. Parents or legal representatives provide consent for children to participate, and children capable of understanding the study will give assent. The total participation duration may extend up to six years and nine months, allowing long-term safety data collection.

This research aims to gather long-term safety and effectiveness information for people treated with ibrutinib, a medicine taken by mouth that blocks a specific enzyme called brutons tyrosine kinase. The study focuses on participants who previously took part in ibrutinib studies that have finished and are still receiving ibrutinib treatment, continuing to benefit from it. It is an open-label study, meaning both participants and researchers know the treatment being given. Participants will continue taking ibrutinib capsules daily at the dose they were given in their prior study until the doctor decides the treatment is no longer helpful due to disease progression or side effects, the participant chooses to stop, other treatment options become available, or the study ends. Safety will be monitored throughout, and effectiveness data may be combined with previous study results. No formal testing of hypotheses is planned in this extension. During the study, participants will be regularly monitored for safety and disease status. The main outcome is the number of participants experiencing side effects within 30 days after the last ibrutinib dose or before starting another cancer therapy. Participants may continue treatment until alternative access to ibrutinib is arranged or the study ends, which is planned for December 2029. Researchers will collect ongoing data to understand the long-term effects of ibrutinib treatment.
