Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Other | Exploratory Efficacy: Prosthetic Use | Average hours of prosthetic use per week averaged across two weeks compared at Month 3, Month 6 and Month 12 to Baseline. | 12 months post implant | |
Primary | Primary Effectiveness Endpoint: Reduction of Pain Level by 50% From Baseline | Demonstration of 50% reduction in a Numerical Rating Scale (NRS) pain score from pre-treatment to post-treatment for more than 50% of all pain episodes. Study success will be determined by a superiority test on the difference between responder rates in the Test group (those receiving the treatment) and Control group (those who do not receive treatment). | Randomized Testing Window (Month-1 to Month-3 post implant, 2 Month duration) | |
Primary | Primary Safety Endpoint: Incidence of Reported and Adjudicated Serious Adverse Events | Incidence of all serious adverse events including serious adverse device events and unanticipated adverse device events. | From screening injection visit through 3 months post implant | |
Secondary | Secondary Effectiveness: Pain Relief After 2 Hours | Average percent change of pain intensity from before treatment, 30 minutes post treatment, and 2 hours post treatment | 12 months post implant | |
Secondary | Secondary Effectiveness: Pain Days Per Week | Average number of pain days compared at Month 3, Month 6 and Month 12 to Baseline. | 12 months post implant | |
Secondary | Secondary Effectiveness: Pain Medication Use | Average morphine equivalent dose per day over two weeks compared at Month 3, Month 6 and Month 12 to Baseline. | 12 months post implant | |
Secondary | Secondary Effectiveness: Pain Interference to Activities of Daily Living (ADL | Brief Pain Inventory summary score compared at Month 3, Month 6 and Month 12 to Baseline. | 12 months post implant | |
Secondary | Secondary Effectiveness: Health-related Quality of Life (HR-QOL) | EQ-5D summary index, SF-12 physical component and mental component summary compared at Month 3, Month 6 and Month 12 to Baseline. | 12 months post implant | |
Secondary | Secondary Effectiveness: Patient Global Impression of Change (PGIC) | Comparison of Patient Global Impression of Change across the Month 3, Month 6 and Month 12 office visits | 12 months post implant | |
Secondary | Secondary Safety | Incidence of all Non-Serious Adverse Events, including Non-Serious Adverse Events, Non-Serious Adverse Device Events, and Unanticipated (Non-Serious) Adverse Device Events from the time of consent through 12 months post implant. | 12 months post implant |
