The primary endpoint was change in Item 1 on the Orthostatic Hypotension Symptom Assessment (OHSA) scale at Week 1. Item 1 assessed patients’ self-reported symptom ratings for dizziness, lightheadedness, feeling faint, or “feeling like you might black out.”1,2
a Based on 89 patients; 2 patients on NORTHERA were randomized but never treated.2
b Based on 85 patients; 1 patient on placebo was randomized but never treated.2
Concomitant medication use was common in Study 306B for patients taking both droxidopa and placebo.2
Concomitant Medications in Phase 3 Trials Included1:
No dedicated drug-drug interaction studies were performed for droxidopa.1
cStudy 301 included patients with primary autonomic failure and non-diabetic autonomic neuropathy with symptomatic nOH.2
dStudy 302 included patients with primary autonomic failure, dopamine beta-hydroxylase deficiency, and non-diabetic autonomic neuropathy with symptomatic nOH.2
eStudy 303 included patients with primary autonomic failure, dopamine beta-hydroxylase deficiency, and non-diabetic autonomic neuropathy with symptomatic nOH.2
Studies 301, 302, and 303 failed to reach statistical significance in their primary endpoint analyses. Considering these data, the effectiveness of NORTHERA beyond 2 weeks is uncertain, and patients should be evaluated periodically to determine whether NORTHERA is continuing to provide a benefit.1
