NCT ID: NCT05000320 Withdrawn - Status Epilepticus Clinical Trials

VIGAB-BIOSTAT: Neuronal Injury Panel Substudy

Start date: January 2023
Phase:
Study type: Observational

The purpose of this substudy is to collect and analyze control data to characterize the degree of neuronal injury in PASE patients who have not received vigabatrin to later compare with patients who received this therapy and expand data on the utility of the neuronal injury panel for neuroprognostication. Data from this cohort will be compared with the data generated by the treatment cohort in the main VIGAB-STAT study.

NCT ID: NCT04758052 Withdrawn - Clinical trials for Spinal Cord Injuries

Tracheostomy With Bedside Simultaneous Gastrostomy Vs Usual Care Tracheostomy And Delayed Gastrostomy Placement

BEGASTON
Start date: March 31, 2021
Phase: N/A
Study type: Interventional

There is currently no prospective study analyzing the effect of tracheostomy with bedside simultaneous gastrostomy versus tracheostomy with delayed gastrostomy placement (TSG versus TDG) on the outcomes of neurocritically-ill patients. The investigators will study TSG via concomitant PDT and PUG procedures, while TDG will occur per usual care. This study is a prospective randomized open-label blinded endpoint study to assess the effect of tracheostomy with bedside simultaneous gastrostomy (TSG) versus the usual care of tracheostomy with delayed gastrostomy (TDG) placement on outcomes of neurocritically-ill patients.

Hybrid Device DIALYTRODE for Multimodal Neuro-monitoring of Patients With Brain Injury and Status Epilepticus

Start date: March 2019
Phase: N/A
Study type: Interventional

This clinical trial evaluates the safety and diagnostic performance of a newly developed combined catheter that will be implanted into the brain of patients with severe brain injury for short time (up to 28 days) monitoring of the electric activity and the metabolism of brain tissue at risk. Ten patients will be monitored with the new device and seven patients will be monitored by intracerebral probes according to standard treatment.

NCT ID: NCT03115489 Withdrawn - Refractory Epilepsy Clinical Trials

Efficacy of Ketamine Infusion Compared With Traditional Anti-epileptic Agents in Refractory Status Epilepticus

Start date: May 4, 2017
Phase: Phase 2/Phase 3
Study type: Interventional

The study will investigate the efficacy of the N-methyl-D-aspartate receptor antagonist ketamine as a first line agent in refractory status epilepticus versus traditional general anesthetic agents used for burst suppression that target the gamma-aminobutyric acid adrenergic receptors.

NCT ID: NCT02726867 Withdrawn - Epilepsy Clinical Trials

Levetiracetam, Lacosamide and Ketamine as Adjunctive Treatment of Refractory Status Epilepticus

Start date: February 2014
Phase: Phase 3
Study type: Interventional

The purpose of the study is to evaluate the efficacy and safety of levetiracetam , lacosamide and ketamine treatment of refractory status epilepticus. This will be a randomized, open-label, four-arm pilot study comparing time to cessation of refractory status epilepticus, determined by continuous EEG monitoring, in patients with refractory status epilepticus. Patients with status epilepticus who have been treated with standard dose lorazepam (or midazolam) and ≥ 1000 mg phenytoin with documented levels of ≥20 mg/ml and continue to have clinical status epilepticus for ≥1-24 hours after phenytoin loading will receive intravenously (i.v.) either 4000 mg levetiracetam, 600 mg lacosamide (Group B), 2.5 mg/kg ketamine or phenobarbital 15 mg/kg phenobarbital (Group D)

NCT ID: NCT00603135 Withdrawn - Clinical trials for Status Epilepticus, Non-Convulsive

Intravenous Levetiracetam as First-line Anticonvulsive Treatment in Patients With Non-convulsive Status Epilepticus

Keppra
Start date: January 2008
Phase: Phase 2
Study type: Interventional

Status epilepticus (SE) represents the most common life-threatening neurological emergency requiring treatment on an intensive care unit. The incidence in Western European countries is about 12-18/100'000. Immediate and effective treatment of SE is obviously essential because of the deleterious effects of continuous seizures on the brain and the whole organism. Guidelines emphasize the use of benzodiazepines (BZD) as first-line anticonvulsive drugs. Alternatively, i/v Phenytoin (PHE), fosphenytoin (FOS), and valproate (VPA) were also tested as first-line anticonvulsants in SE. Direct comparison of PHE with lorazepam (LZP) showed significant superiority of LZP (evidence class I). Other trials i/v PHE or -VPA are of evidence class III or IV. BZD, VPA, and PHE have clinical and pharmacological disadvantages. BZD may cause respiratory depression or sedation and may be not suitable for patients with COPD or ambiguous in patients with BZD addiction. Some compounds also may induce tachyphylaxis or accumulate under concomitant renal failure. PHE has saturable metabolism subject to Michaelis-Menten kinetics increasing the risk of overdosing in an acute setting causing liver damage, serious cardiac arrhythmias, hypotension, cerebellar degeneration, peripheral neuropathy and local/systemic skin reactions. Although of unequivocal efficacy, PHE should no longer be used for long-term because of its adverse effects after chronic administration (irreversible cerebellar degeneration causing debilitating ataxia, painful polyneuropathy, and osteopenia increasing the risk of fractures). Metabolism by and self-induction of the hepatic CYP450 system make PHE prone to interactions with several other drugs, notably other antiepileptics. VPA may cause liver failure, hemorrhagic complications, pancreatitis, and hyperammonemic encephalopathy. To summarize, these three first-line agents for the treatment of SE may cause serious side effects in several patients with SE. Levetiracetam (LEV) is broad-spectrum antiepileptic drug. It binds to the presynaptic vesicular protein 2A abundantly present in different regions of the brain; LEV presynaptically modulates transmitter release, but the exact mechanism(s) remain unclear. Data also revealed that LEV stabilizes GABAA receptors upon repetitive activation what is important in treatment of SE because GABAA receptors undergo significant changes of subunit conformation within minutes after sustained activation like during SE. These changes render GABAA receptors the less anticonvulsive, the longer SE lasts. Levetiracetam has a favorable pharmacological profile with large safety margins. Its partly extrahepatic hydrolyzation bypasses the CYP450 system; renal excretion is 60-70% unchanged, and 23-27% metabolized. Dosage needs adjustment when renal function is impaired. LEV lacks interactions with any drugs yet. Drowsiness is the most common side-effect while respiration, liver and kidney function, and the blood system are not affected. LEV shows an important clinical effect even after the first dose and maximal efficacy within the first week of drug-intake. The favorable clinico-pharmacological profile predilects LEV for the first-line treatment of SE, especially in patients with multi-organ failure, sepsis, coma etc.. About 10 % of comatous patients may be in non-convulsive SE (NCSE) on ICU's. These patients are under polymedication whereby interactions of the anticonvulsants approved yet for the treatment of NCSE with their other drugs may have fatal effects. Conversely, non-interacting anticonvulsants would represent an advantage for the treatment of NCSE for these patients. Recently, the i/v formulation of LEV was approved by the FDA for the use in patients, but not specifically for the treatment of SE. Data about the single-dose bioavailability of i/v-LEV in comparison to oral tablets as well as multiple-dose pharmacokinetics and tolerability in healthy subjects were recently published. In addition, the administration of i/v-LEV dosages ranging from 2000-4000 mg within 15 minutes and of dosages ranging from 1500-2500 mg within 5 minutes was safe and well tolerated, and led to efficacious drug levels in a randomized, single-blind, placebo-controlled safety and pharmacokinetic study in healthy volunteers. Slight somnolence is expected to be the only adverse effect of i/v LEV, sharply contrasting with the sedation up to coma after i/v benzodiazepines. Thus, even severely ill patients will be accessible to neurological tests under LEV which is a big advantage in this clinical difficult setting of NCSE. I-v LEV is considered an ideal candidate for the first-line use (before benzodiazepines) in patients with NCSE, especially in those with important comorbidity and concomitant polymedication. Thus, we would like to test the feasibility, safety, and efficacy of i/v-LEV as first-line medication in a open-label, single-center, prospective pilot study as outlined below.
