Brief Summary

The purpose of this study is to test the safety and efficacy of study drug LY3526318 for the treatment of diabetic peripheral neuropathic pain (DPNP). 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.

Conditions

Diabetic Peripheral Neuropathic Pain

Outcome Measures

Primary Outcomes (2)

• 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 intervals was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.

  Baseline, Week 4

• 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% credible intervals was derived using Bayesian mixed model repeated measures. Data presented are posterior mean with 95% credible interval.

  Baseline, Week 8

Secondary Outcomes (14)

• Change From Baseline in the Brief Pain Inventory-Short Form Modified (BPI-SFM) Total Pain Interference Score

  Baseline, Week 4

• Change From Baseline in the Brief Pain Inventory-Short Form Modified (BPI-SFM) Total Pain Interference Score

  Baseline, Week 8

• Change From Baseline for Overall Improvement as Measured by Patient's Global Impression of Change

  Baseline, Week 4

• Change From Baseline for Overall Improvement as Measured by Patient's Global Impression of Change

• Have a history of daily pain for at least 12 weeks based on participant report or medical history.
• 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 pain medications taken for chronic pain conditions for the duration of the study.
• Have daily symmetrical foot pain secondary to peripheral neuropathy present for at least 6 months and as diagnosed through use of the Michigan Neuropathy Screening Instrument Part B ≥3 (©University of Michigan).

• Have surgery planned during the study for any reason, related or not 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.
