Secondary Outcome Measures:
  • Change From Baseline in Severity of Chronic Low Back Pain as Measured by NRS-Pain [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Change From Baseline in Severity of Low Back Pain as Measured by Visual Analogue Scale (VAS) [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Patient's Global Assessment of Disease Activity [ Time Frame: Week 6/ET ] [ Designated as safety issue: No ]
  • Physician's Global Assessment of Disease Activity [ Time Frame: Week 6/ET ] [ Designated as safety issue: No ]
  • Change From Baseline in Roland-Morris Disability Questionnaire (RMDQ) Total Score [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Change From Baseline in Modified Brief Pain Inventory (m-BPI-sf) [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Change From Baseline in Medical Outcomes Study (MOS) Sleep Scale [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Number of Subjects With Change From Baseline in MOS Optimal Sleep Scale Scores [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Change From Baseline in Work Limitations Questionnaire (WLQ) [ Time Frame: Baseline, Week 6/ET ] [ Designated as safety issue: No ]
  • Patient's Global Evaluation of Study Medication [ Time Frame: Weeks 1, 3, and 6/ET ] [ Designated as safety issue: No ]
  • Patient's Satisfaction Questionnaire (With Pain Relief Scale) [ Time Frame: Week 6/ET ] [ Designated as safety issue: No ]
  • Patient's Satisfaction Questionnaire (With Walking and Bending Ability Scale) [ Time Frame: Week 6/ET ] [ Designated as safety issue: No ]
  • Chronic Low Back Pain Responders Based on VAS, Patient's Global, and RMDQ [ Time Frame: Week 6/ET ] [ Designated as safety issue: No ]
