Brief summary
The objective of the proposed study is to conduct the first ever prospective, dose-exploration trial to test the feasibility of early administration of gabapentin as an intervention for neurorecovery. This research project falls under the Intervention Development stage of research as the primary goal is to assess the feasibility of conducting a well-designed intervention efficacy study in the future.
Detailed description
Gabapentin is a medication commonly used in spinal cord injury (SCI) to manage neuropathic pain. Emerging preclinical and clinical evidence suggests that early initiation of low to medium doses of gabapentin and continued delivery for a range of 2 weeks to 4 months has a persistent, positive effect on motor and autonomic neurologic recovery. The objective of the proposed study is to conduct the first ever prospective, dose-exploration trial to test the early administration of gabapentin as an intervention for neurorecovery. A mock efficacy design will be employed. Participants will be stratified based on ASIA Impairment Scale (AIS) grade A-B or C-D and randomized to 1 of 3 arms. Study medication will be initiated within 5 days post-injury and administered for 90 days. Participants will be followed for an additional 90 days after stopping treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of participants recruited | During the first 120 hours post-injury | Feasibility question - Can the target population be recruited? Feasibility measure - Number screened/month; number enrolled/month; reasons for not enrolling Quantitative benchmark of success - Screen an average of 4/month; Enroll an average of 1/month |
| Adherence rate to drug treatment protocol | Across 90 day treatment window | Feasibility question - Can the drug treatment protocol be delivered? Feasibility measure - Proportion of enrolled who receive the full drug treatment protocol (placebo arm; two gabapentin dose arms); number of dosing deviations/arm; reasons for dosing deviations Quantitative benchmark of success - 70% enrolled in placebo arm receive full dosing protocol; 70% enrolled in each gabapentin arm receive full dosing protocol |
| Number of occurrences of unblinding | Across 6 month study duration per participant | Feasibility question - Can the assessors remain blinded? Feasibility measure - Number of occurrences of unblinding; reasons for unblinding Quantitative benchmark of success - 5% or fewer occurrences of unblinding |
| Retention rate | Across 6 month study duration per participant | Feasibility question - Will participants complete the study? Feasibility measure - Retention rate; reasons for dropout; proportion of planned assessments completed Quantitative benchmark of success - 70% of participants stay enrolled until the end of the study and complete 3 of the 4 assessment visits |
