Clinical Trial Summary

The purpose of the clinical trial is to learn whether electrical nerve block via the Altius System is a safe and effective treatment for patients with post-amputation pain.


Description:

The Altius System is an implanted device designed to electrically block nerve signals and alleviate pain. Use of this device may be associated with providing an effective, mechanism-based yet non-destructive, treatment for managing intractable limb pain in amputees. In a given patient, the Altius System will be deemed effective if treatment results in 50% reduction of pain score for more than 50% of all pain episodes.

Outcome

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
