- •Have a body mass index <40 kilograms per meter squared (kg/m²) (inclusive).
- •Are willing to maintain a consistent regimen of any ongoing nonpharmacologic pain-relieving therapies (for example, physical therapy) and will not start any new nonpharmacologic pain-relieving therapies during study participation.
- •Are willing to discontinue all medications taken for chronic pain conditions for the duration of the study.
- •Have a history of low back pain for at least 3 months located between the 12th thoracic vertebra and the lower gluteal folds, with or without radiation.

- •Have surgery planned during the study for any reason, related or not to the disease state under evaluation.
- •Have, in the judgment of the investigator, an acute, serious, or unstable medical condition or a history or presence of any other medical illness that would preclude study participation.

结局指标
主要结局
Change From Baseline for Average Pain Intensity as Measured by the Numeric Rating Scale (NRS)
时间窗: Baseline, Week 8
The NRS was used to describe pain severity. Participants were asked to describe their average pain over the past 24 hours, on a scale of 0 to 10: 0 = no pain, and 10 = pain as bad as you can imagine. Posterior mean change from baseline, 95 percent (%) credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
次要结局
- Change From Baseline for Worst Pain Intensity as Measured by NRS(Baseline, Week 8)
- Change From Baseline on the EuroQuality of Life Five Dimensions (5D) Five Level (5L) Questionnaire (EQ-5D-5L) Health State Index (United States Algorithm)(Baseline, Week 8)
- Change From Baseline on the Roland Morris Disability Questionnaire (RMDQ)(Baseline, Week 8)
- Change From Baseline for Overall Improvement as Measured by Patient's Global Impression of Change(Baseline, Week 8)
- Change From Baseline on the Visual Analog Scale (VAS) for Pain(Baseline, Week 8)
- Change From Baseline on the Sleep Scale From the Medical Outcomes Study (MOS Sleep Scale) - Average Hours of Sleep(Baseline, Week 8)
- Total Amount of Rescue Medication Use as Measured by Average Daily Dosage(Week 8)
