Official Title  ICMJE A Phase 3, Randomized, Double-blind, Parallel, Placebo-controlled, Multicenter Study, With Optional Open-label Continuation, Of The Efficacy And Safety Of Vanquix(tm) Auto-injector (Diazepam Injection) For The Management Of Selected, Refractory, Patients With Epilepsy Who Require Intermittent Medical Intervention To Control Episodes Of Acute Repetitive Seizures
Brief SummaryTo evaluate the efficacy and safety of diazepam in the management of refractory epilepsy in selected patients who require intermittent medical intervention for the control of episodes of acute repetitive seizures. In addition, to assess the support provided by caregivers who are not themselves or not under the direct supervision of health care professionals at the time of administration.
Detailed DescriptionNot Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: Randomized

Intervention  ICMJE
  • Drug: Placebo
    Intramuscular autoinjector; administered at onset of an episode
  • Drug: Vanquix Auto-Injector (Diazepam Injection)
    Intramuscular autoinjector: 5, 10, 15, or 20 mg (based on participant's age and weight); administered at the onset of an episode
Study Arms  ICMJE
  • Placebo Comparator: Placebo
    During the Double-blind Period, participants received a single, age- and weight-appropriate dose of placebo solution as a deep intramuscular injection in the mid to outer thigh. Drug was administered by a caregiver using a spring-driven, pressure-activated, prefilled autoinjector at the onset of an episode of acute repetitive seizures (ARS).
    Intervention: Drug: Placebo
  • Experimental: Diazepam
    During the Double-blind Period, participants received a single, age- and weight-appropriate dose of diazepam solution, ranging from 0.2 to 0.5 mg/kg, as a deep intramuscular injection in the mid to outer thigh. Additional doses were permissible during the Open-label Period. Drug was administered by a caregiver using a spring-driven, pressure-activated, prefilled autoinjector at the onset of an episode of ARS.
