What is being measured
The primary outcome is the main question the study is designed to answer.
Change From Baseline in 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. Data presented are posterior mean with 95% credible interval.
Measured: Baseline, Week 8
Secondary outcomes (7)
Change From Baseline in the Brief Pain Inventory-Short Form Modified (BPI-SFM) Total Pain Interference Score
The BPI-SFM is a numeric rating scale that assesses the severity of pain (severity scale), its impact on daily functioning (Pain Interference scale), and other aspects of pain (for example, location of pain, relief from medications). BPI-SFM pain interference scale has been reported here. Pain interference scale has 7 items, including general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life assessed on 10-point scale. All the 7-items are averaged to produce a total score ranging from 0 to 10 where, 0=no interfere to 10=completely interferes and the mean is reported here. Higher score represents worse outcome. 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.
Measured: Baseline, Week 8
Change From Baseline for Overall Improvement as Measured by Patient's Global Impression of Change
Patients 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 change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Measured: Baseline, 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 change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Measured: Baseline, Week 8
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.
Measured: 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.
Measured: Baseline, Week 8
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 change from baseline, 95% credible interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Measured: 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)
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 interval was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.
Measured: Baseline, Week 8

A Phase 2 study testing LY3556050 in people with Diabetic Peripheral Neuropathic Pain, run by Eli Lilly and Company at 37 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 2 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 37 sites in United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change From Baseline in Average Pain Intensity as Measured by the Numeric Rating Scale (NRS) (time frame: Baseline, Week 8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2023.
