Clinical Trial Summary

Primary Objective: The primary objective of this study is to compare postsurgical opioid consumption through 72 hours postsurgery in patients receiving local infiltration analgesia (LIA) with EXPAREL and bupivacaine HCl (EXPAREL group) with that of patients receiving standard of care (SOC) (control group) in adult subjects undergoing posterior lumbar spine surgeries where both groups are receiving a multimodal pain regimen. Secondary Objectives: The secondary objectives of this study are to: 1. Compare safety and effectiveness outcomes following LIA with EXPAREL and bupivacaine hydrochloride (HCl) versus SOC in adult subjects undergoing posterior lumbar spine surgeries through 72 hours, including time to first opioid and opioid-related adverse events (ORAEs). 2. Compare health outcomes following LIA with EXPAREL and bupivacaine hydrochloride (HCl) versus SOC in adult subjects undergoing posterior lumbar spine surgeries, including discharge readiness, hospital (or other facility) length of stay (LOS), discharge disposition, hospital readmissions, and health service utilization.

Description:

This is a Phase 4, multicenter, prospective, active-controlled, real world, study in approximately 225 adult subjects undergoing posterior lumbar spine surgery under general anesthesia. Subjects will be screened within 30 days prior to surgery; screening on the day of surgery will be allowed but is discouraged. If a subject can only be screened on the day of surgery, the informed consent process must still be started at least 24 hours prior to the conduct of any screening procedures that are not considered SOC at the institution and such procedures may not be performed until written informed consent is provided. All screening procedures that are not SOC must be performed and documented within the 30-day time window (inclusive of the day of surgery for those subjects who can only be screened on the day of surgery) as described here. During the screening visit, subjects will be assessed for any past or present medical conditions that in the opinion of the investigator would preclude them from study participation. After the ICF is signed, the following information will be recorded and procedures done: medical history, surgical history, medication history, the subject's opioid use history will be recorded to calculate mean daily mg oral morphine equivalent dosing (MED PO) in the last 30 days, demographic and background information, height, weight and body mass index (BMI), a urine pregnancy test for women of childbearing potential, and the subject's current adverse experiences (AEs), if any. Subjects will be asked questions and/or be asked to fill forms as part of the following assessments: Brief Pain Inventory - short form (BPI-sf), 5-item Opioid Compliance Checklist (OCC), Hospital Anxiety and Depression Scale (HADS), Survey of Pain Attitudes (SOPA), Numeric Rating Scale (NRS) ti assess pain and Opioid Related Symptom Distress Scale (ORSDS). Based on the planned surgical procedure, subjects will be placed in one of three cohorts: - Cohort 1 - Open lumbar spinal fusion technique; ("open" cohort) - Cohort 2 - Minimally invasive tubular and/or percutaneous pedicle screw insertion for lumbar decompression with or without fusion;("tubular/percutaneous without midline incision" cohort) - Cohort 3 - Lumbar decompression surgery (LDS) without fusion (discectomy or laminectomy outpatient cohort) The initial sample size in each study cohort (i.e., cohort 1, cohort 2 and cohort 3) is estimated at 75 subjects (50 subjects with EXPAREL and 25 subjects with Control group), for a total of 225 subjects in all three cohorts. Within each assigned cohort, subjects will be allocated in a 2:1 ratio to the EXPAREL (50 subjects) and Control group (25 subjects). The following sequence will be followed for all cohorts: First, the subjects who meet eligibility criteria will be treated according to the institution's SOC. Their data will be collected prospectively. Next, at each investigational site, the administration of EXPAREL and bupivacaine HCl to the first 1 to 3 subjects in each cohort will be observed to ensure that the correct procedure for infiltration as described in the infiltration guide is being followed. If the infiltration was performed correctly, the subject will be included in the study. If the infiltration was performed incorrectly, the subject will continue in the study but will be removed from statistical analysis and will be replaced to ensure at least 50 evaluable EXPAREL patients are enrolled per cohort. If subjects are discontinued for other reasons, they will be replaced such that a total sample size of 75 fully evaluable subjects is obtained in each study cohort, with 50 in the EXPAREL group and 25 in the Control group.
