Outcome Measures
Primary Outcome Measures
- Average change from baseline to 3 months in treatment responder rates [3 months]
Responder is defined as a subject who has at least 50% reduction in lower limb pain from baseline as measured by a 10 cm Visual Analog Scale (VAS).
Secondary Outcome Measures
- Average change from baseline to 6 months in treatment responder rates assessed by Visual Analog Scale (0-10 cm) [6 months]
0 no pain at all, 10 worse pain imaginable
Other Outcome Measures
- Percentage of patients with change from baseline in sensory neurological assessment at 3 months [3 months]
Assessed by the healthcare provider.
- Average change from baseline to 3 months in severity of neuropathic pain as measured by Neuropathic Pain 4 Questions (DN4) (0-10) [3 months]
score of 4 or greater indicates neuropathic pain
- Average change from baseline in CGM metrics from AGP report at 3 months [3 months]
- Average change from baseline in health-related quality of life at 3 months as assessed by Patient-Reported Outcomes Measurement Information System (PROMIS-29) [3 months]
- Average change in proportion of remitters (remission is defined as having a lower limb pain Visual Analog Score score ≤ 2.5 cm) at 6 months [6 months]
- Average change in health-related quality of life as assessed by Patient-Reported Outcomes Measurement Information System (PROMIS-29) at 6 months [6 months]
- Average change from baseline to 3 months in opioid dosage measured in total morphine milligram equivalents (MME) [3 months]
- Proportion of participants with clinically meaningful improvement on sensory neurological examination as determined by the investigator at 6 months compared to baseline. [6 months]
- Average change from baseline to 6 months in opioid dosage measured in total MME [6 months]
- Average change from baseline to 6 months in severity of neuropathic pain as measured by DN4 [6 months]
- Difference in average percentage change from baseline in CGM metrics from AGP report at 6 months [6 months]
- Assessment of subject outcomes satisfaction as measured through Patient Global Impression of Change (PGIC) (1-7 where higher scores mean better outcome) at 3 months and 6 months. [3 & 6 months]
