Study Endpoints

Primary Endpoints

Change From Baseline for Average Pain Intensity as Measured by the NRS
Baseline, up to Week 8

The NRS was used during the preliminary data entry period and daily throughout the study 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 interval (CrI) was derived using Bayesian mixed model repeated measures. The Bayesian analyses include posterior probabilities instead of p-values, and 95% credible intervals instead of 95% confidence intervals

Change From Baseline in Average Pain Intensity as Measured by the Numeric Rating Scale (NRS)
Baseline, up to Week 8

The NRS was used during the preliminary data entry period and daily throughout the study 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 interval (CrI) was derived using Bayesian mixed model repeated measures.

Number of Participants Who Were Allocated to Each ISA
Baseline, Up to Week 8
Part B:Change From Baseline in Proteinuria
Baseline, 16 Weeks

Proteinuria is defined as the ratio of protein to creatinine.

Part A and Part B: Number of Participants With One or More Treatment Emergent Adverse Events (AEs) or Any Serious AEs
Baseline up to 32 Weeks

Treatment-emergent adverse events (TEAEs) are events which were not present at baseline or pre-existing conditions at baseline that worsened in severity following the start of treatment. A summary of other non-serious Adverse Events (AEs), and all Serious Adverse Events (SAE's), regardless of causality, is located in the Reported Adverse Events section.

Secondary Endpoints

Change From Baseline on the Roland Morris Disability Questionnaire (RMDQ)
Baseline, up to Week 8
Change From Baseline for Overall Improvement as Measured by Patient's Global Impression of Change (PGI)
Baseline, up to Week 8

Frequently asked questions about LY3016859

What is LY3016859 used for?

LY3016859 is an investigational medicine being studied for chronic pain conditions. Eli Lilly and Company is evaluating it in chronic low-back pain, diabetic peripheral neuropathic pain, and osteoarthritis, including osteoarthritis of the knee. It is not approved for any use and remains in clinical development.

Who is developing LY3016859?

LY3016859 is being developed by Eli Lilly and Company, which trades on the New York Stock Exchange under the ticker LLY. Lilly is running the clinical program, including a chronic pain master protocol that tests the drug across several pain indications.

What phase is LY3016859 in?

LY3016859 is in Phase 2 clinical development. It has been studied in completed Phase 2 trials in chronic low-back pain, diabetic peripheral neuropathic pain, and osteoarthritis, and it continues to be evaluated in a recruiting Phase 2 master protocol in chronic pain.

What clinical trials is LY3016859 in?

LY3016859 has been tested in three completed Phase 2 trials: NCT04529096 in chronic low-back pain, NCT04476108 in diabetic peripheral neuropathic pain, and NCT04456686 in osteoarthritis. It is also included in the recruiting master protocol NCT05986292, which covers knee osteoarthritis, diabetic neuropathic pain, and chronic low-back pain.

Is LY3016859 the same as LY3016859 intravenous or LY3016859 ISA?

Yes. LY3016859 intravenous and LY3016859 ISA refer to the same investigational compound as LY3016859. ISA stands for intervention-specific appendix, the substudy structure used in Lilly's chronic pain master protocol, and intravenous describes the route of administration.

Is LY3016859 FDA approved?

No. LY3016859 is an investigational drug and is not approved by the FDA. It is still in Phase 2 clinical development for chronic pain conditions, including chronic low-back pain, diabetic peripheral neuropathic pain, and osteoarthritis.
