Filter by:Following successful cardiopulmonary resuscitation (CPR) after out of hospital cardiac arrest (OHCA), 50% of patients admitted to the Intensive Care Unit (ICU) die. As most patients die due to brain damage sustained during cardiac arrest and the subsequent reperfusion phase, effective neuroprotective strategies could potentially improve outcome. In animal experiments, 2-Iminobiotin (2-IB), a selective neuronal and inducible nitric oxide synthase (NOS) inhibitor, given upon reperfusion has been shown to improve memory function. Since 2-IB has not shown any safety issues in preclinical and clinical studies. Before embarking on large studies with efficacy as primary endpoint, safety, tolerability and pharmacokinetics need to be established. Objective: Evaluate short term safety and tolerability, and the pharmacokinetic properties of 2-IB in adult patients after OHCA. Study design: Phase 2, single-centre, open-label, dose-escalation intervention study. Study population: Three cohorts of eight evaluable patients admitted to the ICU after OHCA due to a cardiac cause. Intervention: The first eight patients will receive 0,055 mg/kg 2-IB every 4 hours intravenously, 6 times in total (part A). The second eight patients (cohort B) will receive 0,165 mg/kg every 4h iv, 6 times in total. The third eight patients (cohort C) will receive 0,5 mg/kg every 4h iv, 6 times in total. Medication has to be given as soon as possible and within 6h after OHCA. Escalation to the next dose level will only be done after pharmacokinetic analyses have performed, no relevant safety issues have been encountered, and the DSMB approves to move to the next dose level. Main study parameters/endpoints: Study parameters to evaluate short term safety and tolerability will be vital signs (heart frequency, blood pressure, cardiac ischemia) before and until 15 minutes after administration. (Serious) Adverse Events will be recorded on the ICU (up to 7 days) or until discharge from the ICU. For evaluation of the pharmacokinetics profile of 2-IB, 9 plasma samples will be analysed. Secondary parameters: Biochemical markers Neuron specific Enolase and s100b at 24h and 48h after start of study drug, occurrence of SAEs until 30 days after OHCA including death, long term term efficacy as determined by the Cerebral Performance Category (CPC), the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) or the Telephone Interview Cognitive Status (TICS) scale at 30 days after OHCA.
The purpose of this study is to improve the ability of the investigators to monitor brain health in newborn babies at risk of brain injuries. The researchers will be using an investigational system of devices to non-invasively (that, is, without penetrating the skin), measure the amount of oxygen going to and being used by the brain. They will be taking some bedside research measurements during the babies' stay at the hospital. With these measurements, the intention is to study the role of oxygen in brain injury and test the efficacy of the research device and its potential as a permanent bedside diagnostic device.
