NCT02353299

Brief Summary

This is a Phase IV, randomized, double-blind, placebo-controlled, four-arm crossover study. The study will assess the effects of a single dose of Silenor 6 mg compared with matching placebo and a single dose of zolpidem 10 mg compared to its matching placebo at the respective T-max in normal healthy adult male volunteers. The study will be conducted in approximately 52 male subjects

Outcome Measures

Primary Outcomes (1)

  • Auditory Arousal Threshold (AAT) at T-max

    AAT will performed at T-max for Silenor and matching placebo at 4 hours post dose. Assessments performed at t max for zolpidem and placebo at 1.5 hours post dose. An acoustic stimulus (1000 Hz tone) was presented through audiometric earphones (E-A-RTone 3A Insert Earphones). Tones began at 30 dB and increased by 5 dB until the participant woke up or the maximum dB-level (110 dB) was reached.

    at either 1.5 or 4 hours post dose

Secondary Outcomes (6)

  • Tandem Walk Step-Offs

    at either 1.5 or 4 hours post dose

  • Tandem Walk Duration Over Five Trials

    at either 1.5 or 4 hours post dose

  • Berg Balance Test

    at either 1.5 or 4 hours post dose

  • Immediate Free Recall Task

    directly after the encoding task

  • Delayed Free Recall Task

    15 minutes after final awakening the morning

  • +1 more secondary outcomes
