Approximately 482 patients will participate across these parts.

Preterm birth, defined as birth before 37 weeks of gestation, occurs in about 8 percent of pregnancies in Canada and is linked to many health challenges, especially when it happens before 29 weeks. At this early stage, infants often face breathing difficulties and may require resuscitation. This trial compares resuscitation using either low 30% or high 60% oxygen levels to determine which approach results in better survival and neurodevelopmental outcomes at around 24 months of age. The study uses a cluster randomized crossover design where hospitals alternate between starting resuscitation with 30% or 60% oxygen for groups of 30 infants. Resuscitation includes standard care steps like lung expansion and ventilation support as needed. Oxygen is initially given at the assigned concentration for the first 5 minutes, then adjusted based on the infants oxygen saturation levels and heart rate over the next 5 minutes to maintain target saturation ranges. This approach aims to balance risks of too much or too little oxygen. Participants are infants born between 23 and 28 weeks gestation who receive full resuscitation at participating centers. During the study, infants have oxygen saturation monitored continuously, and adjustments to oxygen concentration are made carefully. Researchers will evaluate survival and major neurodevelopmental outcomes at 24 months corrected age, along with several safety and health measures during the neonatal intensive care stay. The trial is expected to provide important evidence to guide oxygen use during resuscitation of extremely preterm infants.

Neuroblastoma is the most common extracranial tumor in children, occurring at a rate of about 10.2 cases per million yearly. This study is a phase II pilot trial designed to assess the use of a new imaging method, 68Ga-DOTATATE PETCT, for detecting neuroblastoma and compare it to the existing 123I-MIBG scan. Researchers aim to evaluate the feasibility and safety of 68Ga-DOTATATE and how accurately it identifies neuroblastoma lesions compared to 123I-MIBG. Participants will first undergo a 123I-MIBG scan followed by a 68Ga-DOTATATE PETCT scan a few days later. The 68Ga-DOTATATE is a radiopharmaceutical injected into the patient, and imaging is done approximately one hour post-injection, lasting about two hours. This single-arm study includes children and young adults up to 21 years old who have biopsy-proven or suspected neuroblastoma. The study monitors adverse events within 24 hours after the 68Ga-DOTATATE injection. During the study, researchers will collect clinical data from the imaging scans and participants medical records for up to two years, including demographics, treatments, medications, pathology, and laboratory tests. Outcome measurements focus on the rate of participant enrollment and any side effects from the 68Ga-DOTATATE injection, as well as lesion detection and differences between the two imaging methods. Participants health status will be followed regularly to assess the imaging techniques effectiveness and safety.

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 a new 10-minute cardiovascular magnetic resonance CMR imaging protocol designed to improve current CMR procedures for patients with various heart conditions, including coronary artery disease, cardiomyopathies, and other cardiac diseases. The study aims to develop a standardized, contrast-free imaging method that can be applied to about 70% of cardiac patients. The goal is to assess whether this shorter protocol enhances diagnostic decision-making and reduces healthcare costs. The study involves two groups healthy volunteers over 18 years old without significant cardiovascular or respiratory conditions, and patients over 18 years who require a clinically indicated CMR exam. The new protocol focuses on heart function and tissue characterization without using contrast agents. Researchers will compare the new 10-minute protocol to standard CMR imaging, evaluating its clinical feasibility, performance, and cost-effectiveness in different patient populations. Participants will undergo CMR scans using both the new and standard protocols. Researchers will monitor diagnostic results, scan completion rates, scan sequence times, adverse events, and cost differences between methods. Various heart tissue measurements and reproducibility between different readers and scanners will also be assessed. The study spans from 2019 to 2025, with ongoing safety monitoring during imaging sequences and a focus on improving the efficiency and quality of cardiac imaging.

Researchers are evaluating the effectiveness of delgocitinib cream 20 mgg applied twice daily compared to a cream vehicle in treating adults with mild to severe palmoplantar pustulosis PPP. This trial is a phase 2a, double-blind study focusing on this skin condition characterized by pustules on the palms and soles. The main goal is to see how well delgocitinib cream improves symptoms over a 16-week treatment period. Participants will be randomly assigned to one of two groups one group will apply delgocitinib cream twice a day for 16 weeks, while the other group will use a matching vehicle cream twice daily for the same duration. The study includes a total of approximately 18 weeks for each participant, involving around 9 visits. The trial compares the active cream to the placebo cream to assess efficacy and safety. During the study, participants will attend scheduled visits to monitor their condition and collect data on skin symptoms, pustule counts, and quality of life measures. Researchers will assess the improvement in PPP severity using specific scales such as the PPP Area and Severity Index PPPASI. Safety is monitored through reports of any treatment-emergent side effects. Overall participation lasts about 18 weeks, including screening and treatment phases.

Researchers are evaluating the effectiveness of delgocitinib cream applied twice daily compared to a cream vehicle for treating adults with mild to severe lichen sclerosus LS, a skin condition affecting mostly females in the anogenital area. The study is conducted in two parts Part 1 enrolls female participants to determine the best dose, and Part 2 includes both female and male participants to further assess the chosen dose and safety in males. Participants receive different dosing regimens of delgocitinib cream or cream vehicle applied twice daily during a 12-week initial treatment period, followed by a 40-week continuation treatment period. Different groups receive varying doses or sequences of delgocitinib cream and cream vehicle to compare effects. A substudy evaluates male participants separately to assess safety and efficacy. During the trial lasting between 55 and 60 weeks, participants undergo regular assessments including clinical evaluations of LS severity using IGA-LS scores, pain and itch numerical rating scales, and quality of life indexes. Safety is monitored through adverse event tracking and laboratory tests. The main outcome measured is the number of participants achieving a specific improvement in LS severity at Week 12, with additional evaluations continuing through Week 52.

Researchers are evaluating calderasib alone or combined with cetuximab to treat people with advanced solid tumors that have the KRAS G12C mutation, excluding colorectal cancer.
