The main purpose of this study is to assess whether LY3857210 is safe and efficacious in relieving chronic low back pain (CLBP). This trial is part of the chronic pain master protocol H0P-MC-CPMP (NCT05986292), which is a protocol to accelerate the development of new treatments for chronic pain.

Change From Baseline for Average Pain Intensity as Measured by the Numeric Rating Scale (NRS)
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. The data presented are the posterior mean with a 95% credible interval.
Time frame: Baseline, Week 8
Change From Baseline on the Roland Morris Disability Questionnaire (RMDQ)
The RMDQ is a simple, sensitive, and reliable method to measure disability in patients with back pain that consists of 24 statements relating to the participant's perceptions of back pain and associated disability based on physical ability/activity, sleep/rest, psychosocial, household management, eating, and pain frequency. Participants are asked if they feel the statement is descriptive of their own circumstance on that day. The total score is obtained by counting the number of ''Yes'' responses, ranging from: 0 = no disability to 24 = maximal disability. Posterior mean change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Time frame: Baseline, Week 8
Mean Overall Improvement as Measured by Patient's Global Impression of Change
Patient's global impression of change captured the participant's perspective of treatment apart from sub-aspects of the general improvement. This is a numeric scale from 1 to 7: 1 = very much better, and 7 = very much worse. Posterior mean, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Time frame: Week 8
Change From Baseline for Worst Pain Intensity as Measured by NRS
The NRS was used to describe pain severity. Participants were asked to describe their worst 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, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.

Change From Baseline on the Visual Analog Scale (VAS) for Pain
VAS was a graphic, single-item scale where participants were asked to describe their pain intensity over the past week, on a scale of 0 to 100: 0 = no pain, and 100 = worst imaginable pain. Participants completed the VAS by placing a line perpendicular to the VAS line at a point that described their pain intensity. Posterior mean change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Time frame: Baseline, Week 8
Change From Baseline on the Sleep Scale From the Medical Outcomes Study (MOS Sleep Scale) - Average Hours of Sleep
The MOS Sleep Scale consists of 12 questions addressing the past week. Question 1 asks time to fall asleep and it is reported in 5-point timeframe categories. Question 2 asks average hours of sleep. In the remaining 10 questions participants report how often a sleep symptom or problem was present on a scale ranging from '0=all of the time' to '5=none of the time.' MOS Sleep scale dimension scores range from 0 to 100 with lower score indicating improvement, except for the dimension of sleep adequacy, where higher scores indicate improvement. Here, the average hours of sleep (i.e., Question 2) is reported as the average number of hours slept each night during the past week (range 0 to 24 hours). Higher number of hours slept indicates improvement. Posterior mean change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.

Total Amount of Rescue Medication Use as Measured by Average Daily Dosage
Total amount of rescue medication use as measured by average daily dosage. Posterior mean and 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.

Change From Baseline on the EuroQuality of Life Five Dimensions (5D) Five Level (5L) Questionnaire (EQ-5D-5L) Health State Index (United States Algorithm)
The EQ-5D-5L assessed quality of life based on 5 dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The participant was asked to 'check the ONE box that best describes your health TODAY,' choosing from 5 options (no problems, slight problems, moderate problems, severe problems, extreme problems) provided under each dimension. The scores in the 5 dimensions were summarized into a health state index score using the United States algorithm. The health state index value is a single value on a scale from less than 0 to 1 (negative values are valued as worse than dead) with higher scores indicating better health: 0=a health state equivalent to death, and 1=perfect health. Posterior mean change from baseline, 95% credible intervals was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
