ABSTRACT
Intranasal formulations are commonly used for drug delivery, and the literature has shown that seasonal allergies do not affect nasal administration of some agents. Diazepam nasal spray (Valtoco®) is a proprietary intranasal formulation with n-dodecyl-beta-d-maltoside (Intravail® A3) that is indicated for acute treatment of seizure clusters in patients with epilepsy aged 6â¯years and older. The analysis presented here is from an interim cutoff of a phase 3 open-label study evaluating the safety and tolerability of diazepam nasal spray. This analysis assessed whether seasonal allergies alter control of seizures with an intranasal formulation, using administration of a second dose as a surrogate efficacy endpoint. Of 158 evaluated patients with epilepsy having seizures despite a stable anti-seizure regimen, 62 patients had medical histories that included seasonal allergies or rhinitis. The results of this analysis show that seasonal allergies did not appear to influence use of a second dose; the groups of patients with and without a history of seasonal allergies both presented with low rates of seizure episodes for which a second dose was used, which suggests that there is not a major difference in pattern of use. Diazepam nasal spray demonstrated a similar safety and tolerability profile in patients with and without a history of seasonal allergies.
