Pilot Study of Dexmedetomidine Sublingual Film for the Ambulatory Treatment of Hyperadrenergic Autonomic Crisis in Patients With Familial Dysautonomia

Running, not enrolling · Phase 2

Conditions studied: Familial Dysautonomia

In brief

This is a pilot open-label study to evaluate the feasibility of conducting a clinical trial using sublingual dexmedetomidine sublingual film to treat hyperadrenergic autonomic crises in patients with Familial Dysautonomia at home. The primary aims are to examine the feasibility of performing a clinical trial using dexmedetomidine at home to terminate autonomic crisis, and refine the interventions and assessments used to evaluate autonomic crisis termination.
