The Up-LIFT Study of Non-Invasive ARC Therapy for Spinal Cord Injury

Not Applicable

Completed

• Conditions: Chronic Spinal Cord Injury
• Interventions: Device: LIFT System

• Registration Number: NCT04697472
• Lead Sponsor: ONWARD Medical, Inc.

Brief Summary

The Up-LIFT Study is a prospective, single-arm study designed to evaluate the safety and effectiveness of non-invasive electrical spinal cord stimulation (ARC Therapy) administered by the LIFT System to treat upper extremity functional deficits in people with chronic tetraplegia.

Detailed Description

The primary endpoint of this pivotal study will report device related safety and changes in established metrics of upper extremity performance after treatment with the study device.

To ensure that the benefits realized in the study are directly attributable to the ARC Therapy, all enrolled subjects will first undergo a guided, in-clinic conventional functional task practice (FTP) program lasting approximately two months to regain their upper extremity (UE) function. Performance gains realized during this wash-in period provide a subject specific control that reflects the limits of conventional functional task practice without stimulation (standard of care). At the conclusion of the wash-in period, subjects will complete pre-stimulation testing of UE function.

To test the additive benefit of training with stimulation, combined functional task practice and ARC Therapy will then be administered over a period of approximately two months using the LIFT System. Functional task practice will follow established rehabilitation protocols that are specific to the individual subject's specific needs and capabilities (Beekhuizen \& Field-Fote, Functional Task Practice versus Functional Task Practice with Stimulation: Effects on Upper Extremity Function and Cortical Plasticity in Individuals with Incomplete Cervical Spinal Cord Injury, 2005). Training will be graded to accommodate performance improvement over time, thus maximizing the potential benefit to subjects. Subjects will participate in up to 20 in-clinic training sessions per month. At the end of training period, the improvement in UE function will be measured and used to assess the progress of primary study endpoints.

The choice of primary outcome measures for this pivotal study is dictated by the following factors -

1. Safety,

2. Relevance to UE function,

3. Capture improvements in performance, and

4. Magnitude of changes that are clinically meaningful.

All performance metrics will be assessed at enrollment, at the completion of the wash-in period and at the end of the ARC Therapy assessment period. Subjects with clinically meaningful gains in multiple performance domains resulting from the ARC Therapy with LIFT will be considered responders. Additionally, gains during the wash-in (control) period will be compared to gains during the ARC Therapy with LIFT (test) period. Safety will be evaluated throughout the entire study through periodic monitoring and analysis of all reported adverse events.

Arm && Interventions

Group	Intervention	Description
Functional task practice (FTP) followed by FTP + ARC Therapy	LIFT System	Clinic-based functional task practice (FTP) for two months followed by FTP + ARC Therapy for an additional 2 months.

Primary Outcome Measures

Name	Time	Method
Incidence of serious adverse events (SAEs)	Through completion of the study, an average of 16 months	Safety demonstrated through observational data regarding the incidence of serious adverse events (SAEs) related to the use of the study device and treatment procedures will be reported.
Number of participants with change in upper extremity strength and function	Through completion of the study, an average of 16 months	Change in upper extremity strength and function performance metrics after treatment with ARC Therapy administered by the LIFT System and Functional Task Practice (FTP) is assessed using ISNCSCI, GRASSP,CUE-T, pinch/grasp forces.; The primary effectiveness outcome measure will test the hypothesis that a majority of the subjects will experience clinically significant improvement in UE performance metrics (defined as therapy responders) after treatment with ARC Therapy administered by the LIFT System and Functional Task Practice (FTP).

Secondary Outcome Measures

Name	Time	Method
Superiority of combined FTP and ARC Therapy with LIFT vs. FTP alone.	Through completion of the study, an average of 16 months	Superiority as demonstrated by statistically significant difference in the proportion of subjects reporting improvement between the two treatment groups.
