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 evaluating the use of 68GaGa-FAPI-46 PETCT imaging in patients with head and neck squamous cell carcinoma HNSCC to improve staging before surgery. The study focuses on cancer-associated fibroblasts CAFs, which contribute to metastasis by remodeling the tumor environment and promoting cancer spread. This trial aims to assess how 68GaGa-FAPI-46 PETCT can identify lymph nodes likely to develop metastases and to enhance tumor delineation in HNSCC patients. Participants will receive an intravenous injection of 68GaGa-FAPI-46 at a dose of 2 MBqkg, with the total dose ranging from 80 to 200 MBq. After about 60 minutes, a low-dose PETCT scan will be performed for approximately 20 minutes. This imaging will be added to the standard pre-surgical imaging protocol, which includes cervical MRI, contrast-enhanced CT, and 18F-FDG PETCT. The study compares PETCT imaging results with the pathology of resected lymph nodes to evaluate the ability of the imaging to detect premetastatic conditions. Participants will undergo standard pre-surgery imaging and lymph node dissection surgery as part of their care. The research team will analyze multiple imaging outcomes at 6 weeks, including tumor size, volume, SUVmax, number and location of lesions, and TNM tumor stage. Secondary outcomes include the ability of 68GaGa-FAPI-46 PETCT to visualize tumor infiltration in lymph nodes after 2 months. The total study duration extends through the surgery and follow-up imaging assessments. Safety and feasibility are monitored throughout the trial.

Researchers are investigating acute myocardial inflammation, a complex condition that includes acute cellular cardiac allograft rejection ACR, cardiac sarcoidosis CS, and immune checkpoint inhibitor induced myocarditis ICIM. This study aims to evaluate the accuracy of 68GaGa-PentixaFor PETCT imaging for detecting inflammatory cells in these patients, offering a potentially non-invasive diagnostic option. The study is a phase 2 trial focusing on these specific heart inflammation conditions where diagnosis is currently challenging. Participants will receive an intravenous injection of a maximum of 50 micrograms of PentixaFor labeled with 150 15 MBq of Gallium-68 68Ga as a bolus 60 15 minutes before undergoing PETCT imaging. The treatment involves this imaging procedure for all three patient groups ACR, CS, ICIM to assess the presence and characteristics of myocardial inflammation. During the study, researchers will evaluate imaging results by analyzing lesion number, location, and standardized uptake value SUV over one year. They will also monitor toxicity data for safety assessment. Participants will have regular clinical follow-ups at the cardiology department. The study involves signing informed consent and includes monitoring for any adverse effects related to the imaging agent or procedures throughout the study duration.

Researchers are exploring new treatment options for neovascular age-related macular degeneration NVAMD, a condition affecting the eyes. This trial aims to compare a new medicine called tiespectus also known as MK-8748 or EYE201 with the standard treatment aflibercept to see if tiespectus works as well in treating NVAMD. The study includes adults aged 50 and older who have not previously received treatment for this condition. Participants will be randomly assigned to one of three groups tiespectus low dose, tiespectus high dose, or aflibercept. Those in the tiespectus groups will receive three initial injections every 4 weeks, followed by injections every 8 weeks up to week 48. After week 48, treatment will continue at intervals based on individual response until week 92. The aflibercept group will receive three initial injections followed by injections every 8 weeks until week 92. During the study, participants will have their vision tested using the Best-Corrected Visual Acuity BCVA score and their eye structure examined with imaging techniques. Researchers will monitor changes in vision over one year and track any side effects up to approximately 96 weeks. Participants will attend regular visits for treatment and assessments throughout the study period lasting about 92 weeks.

Researchers are evaluating the efficacy and safety of trontinemab in people with early symptomatic Alzheimers disease, ranging from mild cognitive impairment to mild dementia due to Alzheimers. This Phase III trial aims to understand how trontinemab affects cognitive decline and disease progression in this population. Participants are randomly assigned to receive either intravenous trontinemab or a placebo in a parallel-group design. Treatment is administered by IV infusion, and the effects are compared over a period of 72 weeks. The study includes comprehensive safety and efficacy assessments throughout this period. During the 72 weeks of the study, participants will undergo various evaluations including cognitive tests such as the Clinical Dementia Rating-Sum of Boxes CDR-SB, Alzheimers Disease Assessment Scales, brain imaging with PET and MRI scans, and biomarker measurements in cerebrospinal fluid and blood. Safety monitoring includes tracking adverse events, infusion reactions, and antibody development. The study requires participants to have a study partner and to complete all study procedures over this time.

Researchers are evaluating the efficacy and safety of rilvegostomig compared to pembrolizumab monotherapy as the first-line treatment for patients with metastatic non-small cell lung cancer mNSCLC whose tumors express high levels of PD-L1. This Phase III, randomized, double-blind, multicenter global study focuses on patients with mNSCLC without certain genetic mutations who are suitable for this treatment approach. Participants are randomly assigned to receive either rilvegostomig or pembrolizumab intravenously on Day 1 of each 21-day cycle. The study compares these two drugs over repeated treatment cycles as first-line therapy. Both treatments are biological agents given by infusion, and the study is designed to monitor their effects over up to approximately five years. During the trial, participants will undergo regular assessments including physical exams, imaging scans such as CT or MRI to measure tumor lesions, and laboratory tests to evaluate organ function. Researchers will closely monitor overall survival, progression-free survival, treatment response, duration of response, and patient-reported outcomes on physical functioning and quality of life. Safety and immunogenicity of rilvegostomig will also be evaluated. Participants are followed and assessed for up to five years to gather comprehensive data on treatment effects and long-term outcomes.

Researchers are evaluating the efficacy and safety of combining durvalumab and domvanalimab compared to durvalumab plus placebo in adults with locally advanced Stage III, unresectable non-small cell lung cancer NSCLC whose disease has not progressed after definitive platinum-based concurrent chemoradiotherapy cCRT. This Phase III, randomized, double-blind, placebo-controlled, international study aims to provide new insights into treatment options for this patient population. Participants will receive either durvalumab and domvanalimab or durvalumab plus placebo as intravenous infusions every four weeks, beginning on Day 1 and continuing for up to 12 months. The study includes two groups one receiving the combination of durvalumab and domvanalimab, and the other receiving durvalumab with a placebo. Both treatments are given through infusion to assess their effects on disease progression and safety. During the trial, participants will undergo regular assessments including monitoring progression-free survival for up to 8 years after randomization. Other measures include overall survival, response rates, duration of response, and various time-to-event outcomes related to disease progression and symptom deterioration. Researchers will also evaluate drug concentrations and immune responses approximately 12 weeks after the last dose. Participants can expect scheduled visits for infusions and evaluations as part of this long-term study.

Researchers are studying the long-term safety of vedolizumab given as a subcutaneous injection to children and teenagers aged 2 to 17 years with moderate to severe active ulcerative colitis UC or Crohns disease CD. The study aims to understand medical problems that may arise from extended use of vedolizumab SC, as well as its impact on hospital visits due to bowel inflammation and on the quality of life for these young participants. This Phase 3b extension study follows participants from an earlier study VedolizumabSC-3003 who have responded well or not to treatment. Participants who responded well to vedolizumab SC in the parent study will continue treatment in this extension study, receiving the same dose and frequency. They will be randomly assigned to receive vedolizumab 108 mg either via a prefilled syringe with an autoinjector pen or with a needle safety device. Dosage is every two weeks for participants weighing at least 30 kg and every four weeks for those weighing between 10 and under 30 kg. Those who did not respond well or recently used corticosteroids will not receive vedolizumab in this study but will be observed in an observational cohort. Throughout the study, participants will visit their study clinic multiple times over up to two years. Researchers will monitor adverse events and serious adverse events up to 18 weeks after the last dose, as well as special safety events in the observational group. They will also assess time to major inflammatory bowel disease-related events and changes in quality of life using the IMPACT-III questionnaire at regular intervals. Participants will have a safety follow-up visit after treatment ends, and those in the observational group will be followed for about two years after their last dose in the parent study.

This trial studies adults aged 50 to under 80 with mild or moderate calcific aortic valve stenosis and elevated lipoproteina levels. Researchers are assessing the safety, tolerability, and ability of pelacarsen TQJ230 given once monthly by injection to slow the progression of this heart valve condition. The study compares pelacarsen to a placebo in a randomized, double-blind design. Participants receive either pelacarsen 80 mg or a matching placebo as a subcutaneous injection monthly. They continue treatment and monitoring for up to 36 months to observe changes in heart valve narrowing and calcium buildup. The study also tracks lipoproteina levels and clinical heart-related events during this period. Throughout the study, participants will have regular assessments including imaging to measure aortic valve function and calcium score, blood tests for lipoproteina, and monitoring for safety. The main outcomes analyzed after 36 months include changes in valve jet velocity and calcium score, alongside clinical events. Participants remain under medical care while being observed for any effects of the study drug or placebo.

Low back pain is a leading cause of disability worldwide and a common reason for primary care visits. This research aims to improve how low back pain is managed in primary care by testing a multilevel intervention developed with general practitioners, physiotherapists, and occupational therapists. The study evaluates the effectiveness of this new care approach compared to usual care, focusing on cost-effectiveness, imaging rates, and patient disability over time. The intervention includes training general practitioners, sending reminders, providing patient education, and using a clinical pathway based on risk of chronicity. Patients may receive education and self-management support, individual physiotherapy sessions after a specialized two-day workshop, and multidisciplinary group management if needed. Care pathways involve screening, follow-up questionnaires assessing risk and work ability, and tailored treatment steps over several weeks, with coordination among healthcare providers encouraged. Participants will be monitored for 12 months through questionnaires at multiple time points and administrative data. Outcomes measured include back-related disability, imaging referrals, opioid and sick leave prescriptions, pain intensity, quality of life, work participation, and beliefs about back pain. Healthcare professionals confidence and beliefs will also be assessed. Implementation outcomes such as acceptability and feasibility will be explored via interviews and focus groups with patients and practitioners to understand integration into routine care.
