Neonatology Complications

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.

Researchers are evaluating the maximum safe and tolerated dose of Levetiracetam LEV for treating neonatal seizures. This Phase IIb, open-label dose-escalation study aims to determine if higher doses of LEV than currently used can improve seizure control in newborns. The study includes infants at risk or confirmed to have neonatal seizures of mild to moderate severity, with continuous video EEG monitoring used to assess seizure activity and control. Participants initially receive a 60 mgkg dose of LEV. If seizures persist after this dose, they are randomized to either receive higher doses of LEV 90 mgkg, 120 mgkg, or 180 mgkg in increments or treatment with Phenobarbital PHB at 20-40 mgkg. Maintenance treatment with PHB may continue for five days either intravenously or orally if tolerated. The study includes three phases, with Phase 3 expanding to neonates with more severe seizure burden if earlier phases show efficacy. Throughout the study, participants are monitored with continuous EEG reviewed by neurophysiologists to assess seizure control over 24 hours and changes in seizure burden during the two hours after treatment. Safety, pharmacokinetics, seizure freedom rates, adverse events, and long-term outcomes up to eight years are evaluated. The study also assesses new technology for neonatal seizure detection. Participation may last several years due to extended follow-up for long-term outcomes.

Researchers are evaluating a predictive tool called the Multifactorial Dynamic Perfusion Index MDPI to estimate the risk of acute kidney injury after cardiac surgery involving cardiopulmonary bypass CPB. This observational study involves adults and infants undergoing cardiac surgery, aiming to validate the MDPI in adults, develop a version for infants under 20 kg, and explore if the MDPI can predict other complications including mortality. The MDPI combines seven variables measured during CPB, many of which can be modified by the surgical team to potentially improve patient outcomes. The study is divided into three parts first, validating the MDPI in 800 adult cardiac surgery patients from two centers using existing CPB monitors that collect data such as hematocrit, oxygen delivery, arterial pressure, and transfusions second, developing a modified MDPI for 200 infants under 20 kg undergoing congenital heart surgery with additional infant-specific variables and third, investigating whether the MDPI can predict other postoperative issues like low cardiac output, longer ICU stays, bleeding complications, and 30-day mortality. Data collection includes parameters recorded during surgery and postoperative creatinine values. Participants will undergo cardiac surgery with CPB, during which relevant physiological data will be continuously recorded by specialized monitors. After surgery, kidney function and other outcomes will be monitored for up to 48 hours, with extended follow-up for complications and mortality over 30 days. Researchers will analyze how well the MDPI predicts acute kidney injury and other clinical outcomes, aiming to incorporate the MDPI into real-time monitoring devices to guide therapeutic decisions during surgery.

Researchers are evaluating a new multi-component score called the Readiness for EXtubation score REXs to predict when ICU patients on invasive mechanical ventilation are ready to be extubated. The process of liberation from mechanical ventilation involves weaning, readiness assessment, and extubation, with success defined as not needing invasive support within 48 hours. This study focuses on developing and analyzing REXs to help clinicians assess extubation readiness more accurately in critically ill patients. The study involves daily screening of ICU patients undergoing weaning from invasive mechanical ventilation. Data collected include clinical parameters such as arterial blood gases, ventilation settings, sedation and agitation scores, heart rate, hemoglobin levels, nutritional status, and cough strength, among others. Clinicians will anonymously enter data into an electronic case report form to develop and evaluate the REXs score. Patients prepared for extubation will have their readiness assessed using this score. Participants will be monitored during their ICU stay, with data collected on extubation success or failure at 24, 48, and 72 hours after extubation. Researchers will also track length of ICU and hospital stays and mortality outcomes. The study uses routine clinical data, with anonymization to protect patient confidentiality. Statistical methods will analyze associations between clinical factors and extubation outcomes to validate the REXs scores predictive ability. The total study duration extends until the end of 2026.

Researchers are conducting a Phase 3 clinical trial to evaluate the safety and effectiveness of AOC 1044, also known as delpacibart zotadirsen, for treating Duchenne Muscular Dystrophy DMD in boys aged 7 to 16 with specific gene mutations suitable for exon 44 skipping. This study is designed as a randomized, double-blind, placebo-controlled trial to assess the impact of this intravenous treatment on muscle function over time. Participants will be randomly assigned to receive either AOC 1044 or a placebo infusion every 6 weeks for 54 weeks, totaling 9 doses during the double-blind treatment period. After this, all participants can join an open-label extension where they receive AOC 1044 every 6 weeks for another 54 weeks, adding 9 more doses. Following the final dose at week 102, participants will have assessments at weeks 108 and 114 to evaluate safety and treatment effects. During the study, participants will undergo various assessments including tests for time to rise velocity, muscle strength, walking and climbing abilities, and quality of life measures. Muscle enzyme levels and global impressions of severity and change from both patients and caregivers will also be monitored. Safety and tolerability will be reviewed regularly by an independent committee. Overall participation lasts over two years, including screening, treatment, extension, and follow-up phases.

Researchers are studying HLX3901 in an open-label, first-in-human phase I clinical trial involving patients with advanced small cell lung cancer SCLC or neuroendocrine carcinoma NEC. The study aims to evaluate the safety, tolerability, and how the drug behaves in the body, focusing on patients who have experienced intolerance, recurrence, or disease progression after prior treatments. The study has two parts Phase Ia uses dose escalation and backfill cohorts where patients receive HLX3901 via intravenous infusion at increasing doses, observing dose-limiting toxicities over 4 weeks. Phase Ib expands the dose to confirm safety and efficacy of HLX3901 monotherapy in selected groups based on Phase Ia data. Participants receive the recommended Phase 2 dose RP2D identified during dose escalation. Participants will undergo screening, treatment cycles of 4 weeks, and monitoring of side effects and tumor response using objective response rates and survival measures over approximately 24 months. Safety reviews guide dosing decisions, and tumor tissue will be collected to test for DLL3 expression. The study involves regular assessments including laboratory tests and imaging to monitor health and treatment effects throughout participation, which can last up to about two years.

Researchers are evaluating the safety and performance of the MOBYBOX System, an extracorporeal cardiopulmonary support device, in patients experiencing cardiac, respiratory, or combined cardiorespiratory failure. The study aims to gather prospective data on how well the device works and its safety profile in real-world use for patients with severe conditions affecting heart and lung function. The MOBYBOX System is used in two configurations veno-arterial for cardiac or cardiorespiratory failure and veno-venous for severe respiratory failure. The device provides extracorporeal support to help patients whose heart or lungs are failing. The study monitors device performance every 4 hours while patients are receiving extracorporeal membrane oxygenation ECMO with the MOBYBOX system and records serious adverse events within 24 hours. Participants will be closely observed during their treatment with the device, with assessments focusing on safety by tracking serious adverse events within 24 hours and mortality within 30 days. Device performance success is also recorded regularly during treatment. The study will continue to follow patients until December 2026, collecting data relevant to the devices safety and effectiveness in supporting heart and lung function in critically ill patients.

Many premature newborns have trouble breathing after birth and receive support with a breathing machine called nasal continuous positive airway pressure NCPAP. When their breathing worsens despite NCPAP, they may be treated with surfactant medication inserted into the windpipe using either a ventilation tube or a thin catheter. This research is studying the use of video laryngoscopes, which have a camera and display the airway on a screen, compared to standard direct laryngoscopes that require doctors to look directly into the babys mouth to insert the tube or catheter. The study aims to see if video laryngoscopy improves the success rate of inserting the thin catheter on the first attempt without causing drops in oxygen or heart rate. The study observes infants who need a thin endotracheal catheter inserted for surfactant administration. It compares two approaches using a video laryngoscope versus a direct laryngoscope during the insertion. This is done across multiple hospitals, each switching from direct to video laryngoscopy over time. The study does not assign which method is used but records which laryngoscope was used for each insertion attempt to compare outcomes. The main focus is on successful first attempts without physiologic instability, as well as secondary measures like number of attempts, duration, oxygen levels, heart rate, and any complications. Participants are newborn infants up to 28 days old who require thin catheter insertion for surfactant treatment and whose parents have consented to share data. Researchers will collect detailed information during and after the insertion attempt, including heart rate, oxygen saturation, duration of the procedure, and any adverse events such as oral trauma or need for chest compressions. Data will be analyzed to evaluate the success and safety of using video versus direct laryngoscopy. The total participation time depends on when the catheter insertion is performed and the follow-up assessments within 72 hours after the procedure.

Researchers are studying the use of two new surgical devices, the Karl Storz Curved and Straight Fetoscopes, to assist in minimally invasive in-utero surgeries. These devices help surgeons see inside the uterus during procedures to treat fetal conditions like twin-twin transfusion syndrome and other complex anomalies. The study aims to assess surgical outcomes, complications, and gestational age in patients treated with these scopes, helping to understand their potential benefits in fetal surgery. The curved fetoscope is designed for patients with an anterior placenta, while the straight fetoscope is used for those with a posterior placenta. Both scopes assist in fetoscopic laser photocoagulation, a procedure that seals abnormal blood vessels in the placenta using laser energy. This research is a non-randomized, single arm study where eligible patients undergo intrauterine procedures with either the curved or straight scopes based on placenta position. The study will collect data on the success of the procedures and related complications for descriptive analysis. Participants will be monitored through the procedure and follow-up until birth and shortly after. The study will evaluate outcomes such as the rate of completed fetoscopic procedures, fetal survival at birth, and various maternal and fetal complications. Researchers will also track gestational age at delivery, procedure length, and short-term neonatal health. The total study duration extends over several years to capture both immediate and longer-term results of using these devices in fetal surgery.

Researchers are evaluating whether the Play and Learning Strategies PALS parenting intervention improves caregiver responsiveness and supports the development of skills and brain growth in toddlers born prematurely. This study focuses on prevention by assessing how responsive parenting affects toddler self-regulation and neurological development. It is sponsored by The University of Texas Health Science Center, Houston. The study compares two groups one receiving the PALS intervention, which teaches a responsive parenting style through nine weekly coaching sessions delivered online via the ENGAGE platform, and a control group provided with weekly developmental milestone information and coach calls. The intervention includes teaching caregivers contingent responsiveness, warm sensitivity, attention maintenance, and verbal scaffolding. Both groups participate over nine weeks, with the control group maintaining communication to match the intervention contact. Participants will take part in assessments at baseline, shortly after the intervention, and again four months later. These assessments include observations of parent-child interactions, toddler attention and emotional regulation tasks, language development inventories, and brain imaging using MRI and EEG. Researchers will measure changes in parental behaviors, toddler skills, neurological markers, and family environment factors. The total participation spans several months, including follow-up evaluations to monitor lasting effects.
