Researchers are evaluating remibrutinib (LOU064) in adolescents aged 12 to under 18 years who have chronic spontaneous urticaria (CSU) that is not well controlled by H1-antihistamines. This Phase 3 trial aims to assess the effectiveness, how the drug is processed in the body, and safety of remibrutinib compared to a placebo. The study also intends to gather long-term data on how well remibrutinib works and its safety over several years after treatment ends. The trial includes three periods. First, the core period is a 24-week double-blind phase where about two-thirds of participants receive remibrutinib and one-third receive placebo, with about 10 site visits over approximately 32 weeks. Next is an optional open-label extension lasting from one to three years, where participants who completed the core period may receive remibrutinib or enter an observational treatment-free phase depending on their symptoms. Participants may cycle through treatment and observational periods up to six times. Finally, an optional long-term treatment-free follow-up can last up to three years with one site visit and up to four phone calls. During the study, participants undergo assessments including changes in urticaria activity scores (UAS7), itching severity (ISS7), and hive severity (HSS7) measured from baseline to 12 weeks. Regular visits monitor safety, symptoms, and drug effects. The study tracks these measures to understand remibrutinib's impact on CSU symptoms and overall safety profile during and after treatment, with total participation potentially lasting several years.

Preterm birth before 37 weeks' gestation is common and linked to many health challenges, especially when it occurs before 29 weeks. At this early stage, infants often face breathing difficulties due to immature lungs, sometimes requiring resuscitation. This study aims to compare two oxygen concentrations, 30% and 60%, used during resuscitation of very preterm infants to determine which leads to better survival and neurodevelopmental outcomes by about two years of age. The study uses a cluster randomized crossover design, where hospitals alternate between using 30% and 60% oxygen to resuscitate infants born between 23 and 28 weeks gestation. Infants receive the assigned oxygen concentration for the first 5 minutes after birth, with adjustments made based on oxygen saturation levels to maintain safe ranges. The intervention lasts 10 minutes, including initial resuscitation and oxygen titration to stabilize the infant. Participants will be closely monitored during their hospital stay and followed up at 24 months corrected age to assess survival and major neurodevelopmental outcomes. Data collected will include oxygen saturation, heart rate during resuscitation, and longer-term health measures. The study's results aim to guide safer oxygen use in resuscitating extremely preterm infants worldwide.

Researchers are evaluating the safety of the PET radiotracer 68Ga-DOTA-TATE in patients with neuroendocrine tumors (NETs). This pragmatic, prospective, and open-label clinical trial aims to establish 68Ga-DOTA-TATE PET/CT imaging as a standard diagnostic tool for NETs across Canada. Previous studies have already shown that this imaging method is superior to the former standard, Octreoscan, and this study seeks to gather additional data to support its routine use in clinical care. Participants receive an intravenous injection of the radiopharmaceutical 68Ga-DOTA-TATE followed by a saline flush. After 45 to 90 minutes, a PET/CT scan is performed to capture detailed images. This single-center study has no control group and focuses on monitoring the safety profile of the radiotracer over a five-year period. During the study, participants will undergo PET/CT imaging after the injection and be monitored for any safety concerns related to the radiotracer. The primary outcome measured is the safety profile of 68Ga-DOTA-TATE over five years. The study involves informed consent and includes patients with suspected or confirmed tumors expressing somatostatin receptors. Researchers will also collect clinical data to help support implementation of this imaging technique as a new standard of care for neuroendocrine tumors.

Neuroblastoma is the most common extracranial tumor in children, occurring in about 10.2 per million children yearly. This phase II pilot study aims to evaluate the feasibility and safety of using 68Ga-DOTATATE PET/CT imaging for detecting neuroblastoma and to compare its imaging results directly with those from 123I-MIBG scintigraphy in the same patients. The study includes both children and adults with confirmed or suspected neuroblastoma, addressing the challenges caused by differences in imaging methods that can lead to varied treatment plans. Participants will receive an injection of the radiopharmaceutical 68Ga-DOTATATE followed by a PET/CT scan lasting about 2 hours, performed a few days after their 123I-MIBG scan. This study uses advanced PET imaging technology that may offer clearer tumor visualization compared to traditional methods. The research is designed as a single-arm, non-randomized trial conducted over a 2-year follow-up period. During the study, clinical data including demographics, treatments, medications, pathology, and lab results will be collected from medical records. Researchers will monitor the rate of participant enrollment throughout the 6-year study duration and track any adverse events occurring within 24 hours after the 68Ga-DOTATATE injection. The study emphasizes safety and effectiveness of the radiopharmaceutical imaging and includes long-term follow-up to assess outcomes.

Researchers are working to create a comprehensive reference database focused on intracranial aneurysms (IA). This project aims to gather detailed clinical history, imaging data, biological samples, and other related information to better understand risk markers for aneurysm formation and rupture, along with prognostic factors for different management strategies. The study also seeks to develop patient-specific management protocols and assess how the database and its tools can improve care, reduce costs, and support new discoveries and industrial developments. Participants include patients with newly diagnosed or known intracranial aneurysms, healthy volunteers, and family members of patients with a familial history of IA. Data collected includes demographic details, medical history, imaging scans such as MRI angiography and CT angiography, and various biological samples like blood, cerebrospinal fluid, saliva, and stool. Participants are asked to provide consent for data and sample use, including genetic analysis and potential future research applications. There are no limits on the number of participants for this database. During the study, participants will provide access to their health records, complete questionnaires, and undergo imaging and sample collection. Researchers will track clinical outcomes, imaging results, and quality of life measures over time. The primary outcome is disease model validation over 5 years. Consent includes provisions for confidentiality, withdrawal without impact on care, and possible re-contact for additional information or consent. The study ensures safety through ethical oversight and insurance coverage for any direct harm related to participation.

Researchers are developing a new cardiovascular magnetic resonance (CMR) protocol that takes only 10 minutes and does not require contrast injection. This protocol aims to improve current CMR techniques by focusing on heart function and tissue characterization. It is designed to be standardized for about 70% of cardiac patients and hopes to enhance diagnostic decision-making while reducing costs. The study will test the new 10-minute CMR protocol in various patient groups, including those with non-ischemic cardiomyopathies, ischemic heart disease, and coronary artery disease. The protocol's clinical feasibility, performance, and cost-effectiveness will be evaluated. Compared to standard CMR, the study will assess how well the new protocol diagnoses heart conditions and its overall impact. Participants will undergo CMR exams using the new protocol. Researchers will monitor outcomes such as diagnosis accuracy and main findings compared to standard CMR from 2019 to 2025. Safety considerations include screening for MRI compatibility and restrictions on caffeine and nicotine use before exams. The study involves adults over 18 years old who provide informed consent, with participation details tailored to both healthy volunteers and patients with cardiac indications.

Researchers are evaluating the effectiveness of delgocitinib cream 20 mg/g applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis (PPP). This phase 2a, double-blind, two-arm trial focuses on adults diagnosed with PPP, a condition characterized by persistent pustules on the palms and/or soles, lasting more than three months. The study aims to assess skin improvement using the PPP Area and Severity Index (PPPASI) and other clinical evaluations over 16 weeks. Participants will be randomly assigned to apply either delgocitinib cream or the cream vehicle twice daily during a 16-week treatment period. The study involves approximately 9 visits over about 18 weeks in total. The trial is designed to compare the two treatments' effects on PPP severity, with a thorough monitoring process throughout the study period. During the trial, participants will undergo clinical assessments including photographic evaluations to confirm PPP diagnosis, PPPASI scoring to measure skin improvement, and physician global assessments. Safety and treatment adherence will be closely monitored. The main outcome measure is the number of participants achieving at least a 75% improvement in PPPASI score from baseline at week 16. The study also includes safety checks and follow-up to ensure participant well-being throughout the trial.

Researchers are evaluating whether an investigational drug called OHB-607 can prevent Bronchopulmonary Dysplasia (BPD), a common chronic lung disease, in extremely premature infants. The study compares infants receiving OHB-607 alongside standard neonatal care to those receiving standard care alone to reduce the burden of this lung condition. This is a Phase 2b, multicenter, randomized, open-label study focused on safety and clinical efficacy. Participants will receive an intravenous infusion of OHB-607 from birth until reaching a postmenstrual age (PMA) of 29 weeks and 6 days. The study includes two arms: one group receives the investigational drug plus standard care, while the other group receives only standard neonatal care. The treatment period ends at 29 weeks plus 6 days PMA, after which infants are monitored. Throughout the study, researchers will track the incidence of severe BPD or death up to 36 weeks PMA, whichever occurs first. Assessments will include clinical evaluations and monitoring for safety and any side effects. The study also involves long-term follow-up to observe the infants' health outcomes beyond the treatment period. Participation involves consent from parents and collection of birth and medical history information.

Researchers are evaluating new treatment options for adults with locally advanced or metastatic colorectal cancer that cannot be removed by surgery and has a specific KRAS G12C gene mutation. This study compares the safety and effectiveness of adding calderasib and cetuximab, both targeted therapies, to a standard chemotherapy regimen called mFOLFOX6. The goal is to see if this combination can help patients live longer without their cancer growing or spreading compared to current treatments that may include mFOLFOX6 with or without bevacizumab. The study has two parts. It involves treatment with calderasib taken as an oral tablet, cetuximab given according to standard procedures, and mFOLFOX6 chemotherapy combining oxaliplatin, leucovorin/levofolinate calcium, and 5-fluorouracil. Some participants may receive bevacizumab or a bevacizumab biosimilar as part of the comparison. The treatments are given following approved dosing schedules. This design allows researchers to assess the safety and tolerability of these drug combinations in treating this type of colorectal cancer with the KRAS G12C mutation. Participants will be monitored for side effects, treatment tolerability, and cancer progression over a period that may last up to about 44 months. Researchers will track outcomes such as how many participants experience dose-limiting toxicities or adverse events, how many stop treatment due to side effects, and progression-free survival time. Assessments include health evaluations, laboratory tests, and imaging to observe cancer status. This long-term follow-up aims to understand both safety and effectiveness of the treatment combinations.

Researchers are studying a medicine called enlicitide to reduce low-density lipoprotein cholesterol (LDL-C) in adults with high cholesterol (hyperlipidemia). This trial aims to find out if taking enlicitide together with rosuvastatin, a standard cholesterol-lowering drug, works better than a placebo in lowering LDL-C levels. The study is a Phase 3 trial that is randomized, double-blind, and placebo-controlled to ensure accurate and unbiased results. Participants will receive oral tablets of enlicitide or placebo along with oral capsules of rosuvastatin or placebo. The study compares the effect of enlicitide plus rosuvastatin against placebo to evaluate their impact on LDL-C. The treatment period lasts 8 weeks, during which participants take their assigned medications as directed. During the study, researchers will measure the average percent change in LDL-C from the start of the trial to week 8. Participants will be monitored for safety and any side effects throughout the study. The total participation time includes screening, treatment, and follow-up assessments to evaluate the medicines' effects and safety in adults aged 18 to 64 with hyperlipidemia.
