Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Pain Related Sleep Interference Scale (PRSIS - Past Week Recall)

    The Pain Related Sleep Interference Scale (past week recall) consists of an 11-point rating scale ranging from 0 (pain did not interfere with sleep) to 10 (pain completely interfered with sleep). Change the rating scale from baseline to week 8 in each group. Subjects are to describe how their pain has interfered with their sleep during the past week by choosing the appropriate number between 0 and 10.

    Baseline, Final Visit (Week 8)

Secondary Outcomes (8)

  • Change From Baseline in Roland Morris Disability Questionnaire (RMDQ)-Total Score-

    Baseline, Visit2 (Week4), Final Visit (Week8 or discontinuation)

  • Change From Baseline in Roland Morris Disability Questionnaire (RMDQ)-Japanese Standardized Score-

    Baseline, Visit2 (Week4), Final Visit (Week8 or discontinuation)

  • Change From Baseline in Pain Numeric Rating Scale (Pain NRS - Past Week Recall)

    Baseline, Visit2 (Week4), Final Visit (Week8 or discontinuation)

  • Change From Baseline in Euro Qol 5-Dimensions (EQ-5D-5L)-QOL-Score-

    Baseline, Visit2 (Week4), Final Visit (Week8 or discontinuation)

  • Change From Baseline in Euro Qol 5-Dimensions (EQ-5D-5L)-Visual Analogue Scale -

    Baseline, Visit2 (Week4), Final Visit (Week8 or discontinuation)
