Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Daily Average Low Back Pain Intensity (LBPI) Score at Week 16: Baseline Observation Carried Forward (BOCF)

    Daily average back pain was assessed on an 11-point numeric rating scale (NRS) captured through an interactive voice response system (IVRS). The participant described the chronic low back pain (CLBP) during the past 24 hours on a scale ranging from 0 (no pain) to 10 (worst possible pain). Baseline value was calculated as mean of the scores over 5 days prior to randomization (initial pain assessment period). Post-baseline value was calculated as mean of the scores over the 7-day period prior to and including the post-baseline visit. Overall possible score range for daily average LBPI at specified visit was 0= no pain to 10= worst possible pain, where higher scores indicated higher pain intensity.

    Baseline, Week 16

Secondary Outcomes (18)

  • Change From Baseline in Roland-Morris Disability Questionnaire (RMDQ) Total Score at Week 2, 4, 8, 12 and 16: Baseline Observation Carried Forward (BOCF)

    Baseline, Week 2, 4, 8, 12, 16

  • Change From Baseline in Patient's Global Assessment (PGA) of Low Back Pain Score at Week 2, 4, 8, 12 and 16: Baseline Observation Carried Forward (BOCF)

    Baseline, Week 2, 4, 8, 12, 16

  • Change From Baseline in Daily Average Low Back Pain Intensity (LBPI) Score at Week 2, 4, 8 and 12: Baseline Observation Carried Forward (BOCF)

    Baseline, Week 2, 4, 8, 12

  • Number of Participants With Cumulative Reduction From Baseline at Week 16 in Daily Average Low Back Pain Intensity (LBPI) Score : Baseline Observation Carried Forward (BOCF)

    Baseline, Week 16

  • Percentage of Participants With at Least 30 Percent (%) and 50% Reduction From Baseline in Daily Average Low Back Pain Intensity (LBPI) Score at Week 2, 4, 8, 12 and 16: Baseline Observation Carried Forward (BOCF)

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Present with duration of low back pain of ≥3 months requiring regular use of analgesic medication (\>4 days per week for the past month). Analgesic medication may consist of NSAIDs, selective COX-2 inhibitors, immediate release opioids, or combinations, with certain protocol-defined limitations.

  • Must meet criteria for pain severity and global assessment of low back pain at Screening and Baseline visits
  • Female patients of child-bearing potential (and male patients with female partners who are of child-bearing potential) must use 2 methods of contraception throughout the study
  • Patients must be willing to discontinue all pain medications for chronic low back pain except rescue medication and not use prohibited pain medications throughout the duration of the study

You may not qualify if:

  • History of lumbosacral radiculopathy within the past 2 years.
  • Back pain due to visceral disorder (eg, endometriosis).
  • Back pain due to major trauma or osteoporotic compression fracture in the past 6 months.
  • History of rheumatoid arthritis, seronegative spondyloarthropathy, Paget's disease of spine, pelvis or femur; fibromyalgia; tumors or infections of the spinal cord.
  • Surgical intervention during the past 6 months for the treatment of low back pain or plans for surgical intervention during the course of the study.
  • Current or pending worker's compensation, litigation, disability, or any other monetary settlement regarding his/her CLBP or any other pain condition, or any closed claim within the past 5 years.
  • Use of any analgesic or muscle relaxant within 48 hours prior to the five days before Baseline
  • Patients receiving only acetaminophen, gabapentin or pregabalin to manage their chronic low back pain.
  • Patients taking \>325 mg/day of aspirin.
  • Use of any antidepressants with the exception of stable treatment with selective serotonin reuptake inhibitors (SSRIs).
  • Use of any sedatives/hypnotics, anxiolytics, tranquilizers, or benzodiazepines unless daily dose has been stable and will remain unchanged throughout the study period.
  • Systemic corticosteroid therapy within 30 days (inhaled and topical corticosteroids are permitted).
  • Local or epidural injection of corticosteroids, as well as injections of corticosteroids in the back within 3 months.
  • Botulinum toxin (Botox®) injection for chronic low back pain within 4 months.
