Primary Purpose: Treatment
Official Title: A Phase III, Randomized Double-Blind, Parallel, Placebo-Controlled, Multicenter Study, With Optional Open-Label Continuation, of the Safety and Efficacy of Vanquix 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

Primary Outcome Measures:
  • Time to next seizure or rescue beginning at least 15 minutes after and within 12-hours of study drug administration (Vanquix or placebo). [ Time Frame: 15 minutes - 2 hours post dose ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Number (%) of patients requiring rescue medication after treatment with study drug [ Time Frame: post-dose ] [ Designated as safety issue: No ]
  • Number (%) of patients requiring emergency room visits after treatment with study drug. [ Time Frame: post-dose ] [ Designated as safety issue: No ]
  • Caregiver global evaluations of treatment outcome, based on seizure frequency, severity, and overall outcome compared to previous episodes. The caregiver global evaluation will be rated on a 10 cm visual analog scale (VAS). [ Time Frame: post-dose ] [ Designated as safety issue: No ]
  • Physician global evaluations of treatment outcome will be rated on a 10 cm VAS. [ Time Frame: post-dose ] [ Designated as safety issue: No ]
