Brief Summary:
CONCERT (Clinical Outcomes in Narcolepsy and Cataplexy: An Evaluation of Reboxetine Treatment) is a Phase 2, double-blind, randomized, placebo-controlled, crossover, multicenter trial of AXS-12 in patients with narcolepsy. The study will enroll approximately 20 patients, all of whom will be treated with AXS-12 for three weeks, and with placebo for three weeks. Eligible patients will be randomized to receive either AXS-12 followed by placebo, or placebo followed by AXS-12. Efficacy assessments will include the frequency of cataplexy attacks, and measures of other symptoms of narcolepsy.

Arm Intervention/treatment
Experimental: AXS-12 (reboxetine) Drug: AXS-12 (Reboxetine)
Dosed orally, twice daily for up to 3 weeks

Placebo Comparator: Placebo Drug: Placebo
Dosed orally, twice daily for up to 3 weeks

Primary Outcome Measures :
  1. Number of cataplexy attacks [ Time Frame: Change from Baseline to end of Week 2 (Period 1) and Week 5 (Period 2) ]

Secondary Outcome Measures :
  1. Epworth Sleepiness Scale (ESS) [ Time Frame: Change from Baseline to end of Week 2 (Period 1) and Week 5 (Period 2) ]
