E.5 End points |
E.5.1 | Primary end point(s) |
The primary efficacy endpoint is defined as the first two thirds of the night (TST2/3) on the worst of 3 nights of sleep calculated from Total Sleep Time as measured by polysomnography. The primary null hypothesis is that there is no difference in TST2/3 between subjects receiving tasimelteon and subjects receiving placebo. TST2/3 will be assessed by analysis of covariance, with treatment group, clinical site, baseline and time zone as a main effect. The primary efficacy analysis will be based on the ITT population.
If the primary null hypothesis is rejected at an alpha level of 0.05, then the step-down primary null hypothesis will also be tested at an alpha level of 0.05 to assess the efficacy of tasimelteon versus placebo as measured by the reduction in the proportion of patients with disturbed sleep on the worst night. The step-down primary endpoint will be summarized and analyzed by a two-sided unconditional exact test, Barnard’s exact test. The ITT population will be used in this analysis.
The Step-down Primary endpoint is to assess the effects of tasimelteon as measured by the reduction in the proportion of patients with disturbed sleep after transmeridian travel on the worst night. |
|
E.5.2 | Secondary end point(s) |
The key secondary/secondary efficacy outcomes include:
• MWT score
• PGI-S score
• TSTfn, LPS, SE and WASO as measured by PSG
• TSTs, SL, SQs as measured by Sleep Diaries KSS score
• JLQ score
For the continuous key secondary or secondary efficacy variables, descriptive statistics will be presented by treatment group, and the scores will be summarized and analyzed in a manner similar to that for the primary endpoint. Categorical variables will also be summarized and evaluated. Details of the analysis and the multiplicity adjustment for the key secondary endpoints and analysis will be described in the SAP. |
