A Master Protocol Study (LY900028) of Multiple Intervention-Specific-Appendices (ISAs) in Participants With Chronic Pain

Study Overview
=================
Brief Summary
-----------------
The purpose of the chronic pain master protocol is to compare independent pain interventions and establish an overarching structure for the disease-state addenda (DSA) and intervention-specific appendices (ISAs). The ISAs may start independently of other ISAs as interventions become available for clinical testing.

Detailed Description
-----------------
The chronic pain master protocol (CPMP) establishes entry criteria and includes DSA for osteoarthritis of the knee, chronic low back pain, and diabetic peripheral neuropathic pain. The DSA have specific study elements to appropriately define the target population and unique scales for assessment. Also, the master protocol governs ISAs that may start independently of other ISAs as interventions become available for clinical testing. Note: Results for all outcomes are posted in the intervention records. No need for duplication.

Eligibility Criteria
