- SECONDARY
- Title
- Maintenance of Entrainment (Cortisol) in Subjects With N24HSWD
- Description
Entrainment is a measure of synchronization of the master body clock to the 24-hour day. The circadian period (τ) was calculated using urinary cortisol collected over four separate 48 hour periods, approximately 1 week apart, during the run-in and randomized phases of the trial. Maintenance of entrainment is defined as the proportion of subjects who become non-entrained to a 24 hour day after randomization to tasimelteon or placebo. Non-entrainment was defined as having a post-baseline τ value ≥ 24.1 or the lower bound of the 95% CI \>24.0.
