Brief summary

The safety and efficacy of AK1320 MS will be evaluated in patients with degenerative spondylolisthesis and concomitant symptomatic spinal stenosis who are undergoing decompression and single level instrumented posterolateral lumber autograft fusion surgery.

Detailed description

This will be a first in human Phase I, ascending dose, multi-center, randomized patient study evaluating the efficacy, safety, PK of AK1320 MS. The study will enroll up to 4 dose escalating cohorts with each cohort having 2 treatment groups. Cohort 1 and Cohort 2 (AK1320 MS group (n=3-7); Control group (n=0-3)) and Cohort 3 and Cohort 4 (AK1320 MS group (n=6-7); Control group (n=0-3)).

Design outcomes

Primary

MeasureTime frameDescription
Incidence of Treatment Emergent Adverse Events (TEAEs) and Serious Adverse Events24 months
Summary of Neurological Status24 monthsNeurological status will be determined preoperatively and postoperatively using a comprehensive neurological status scale. Neurological status is based on four types of measurements: lower extremity motor, dermatomal sensation, reflexes and straight leg raise.

Secondary

MeasureTime frameDescription
Successful Fusion24 monthsFusion will be evaluated through CT scans. Successful fusion will be defined as complete bridging bone between the index level transverse processes with a lack of lucency or lucent lines through the fusion mass.
Oswestry Low Back Pain Disability Questionnaire (ODI)24 months
36-Item Short Form Survey (SF-36v2®)24 months
AK1320 plasma concentrationsPre-op(day 0), Post-op (day 0, day1), 1 week, 2 weeks, 3 weeks, 4 weeks, 5 weeks and 6 weeks
