Overview
Brief Summary
This is a research study testing SABER-Bupivacaine (an experimental pain-relieving medication). SABER-Bupivacaine is designed to continuously deliver bupivacaine, a common local anesthetic, for a few days in order to treat local post-surgical pain.
The purpose of this study is to investigate safety (if there are any side effects) associated with the use of SABER-Bupivacaine and how well it works in reducing pain and opioid-related side effects following shoulder surgery.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Patients must be able to read and understand the consent form, provide written consent, complete trial-related procedures, and communicate with the trial staff.
- •Males and females, 18 to 65 years of age, scheduled for shoulder surgery.
- •Patients must be healthy or have only mild systemic disease.
- •Patients must have ECG wave form within normal limits
- •Patients must have blood pressure within normal range.
- •Male and female patients must agree to use medically acceptable method of contraception throughout the entire trial period and for 1 week after the trial is completed.
- •Patients must refrain from strenuous activities and avoid changes to prescribed exercise levels throughout the course of the trial.
Exclusion Criteria
- •Patients with previous arthroscopic surgery or open surgery on the study shoulder.
- •Patients with chronic pain conditions requiring continuous use of corticosteroids for greater than 3 months.
- •Patients with fibromyalgia, rheumatoid arthritis, and/or sero-negative inflammatory arthropathies.
- •Patients with a below normal calculated creatinine clearance.
- •Patients who are pregnant or lactating.
- •Patients currently receiving more than 20 mg of hydrocodone daily (or equivalent narcotic dose) on routine basis.
- •Patients, who in the Investigator's opinion, have developed opioid tolerance.
- •Patients with current or regular use of anticonvulsants, antiepileptics, antidepressants, or monoamine oxidase inhibitors at screening.
- •Patients with current or regular use of drugs known to significantly prolong the corrected QT interval
- •Patients with known hypersensitivity to local anesthetic agents of the amide type (e.g., lidocaine, bupivacaine).

Outcomes
Primary Outcomes
Mean Pain Intensity on Movement AUC (Time Normalized Area Under the Curve) During the Period 0 to 72 Hours Post-dose.
Time Frame: 0 to 72 hours post-dose
Mean pain intensity on movement AUC (time normalized area under the curve) during the period 0 to 72 hours post-dose. Subjects assessed their pain intensity using an 11-point Pain Intensity Numeric Rating Scale (PI-NRS) with NRS scores ranging from 0 (no pain) to 10 (worst pain possible). The pain intensity AUC on movement was computed for each subject using the standard trapezoidal rule. For the purpose of better clinical interpretability of the pain AUC, a normalized AUC was computed by dividing it using the time-interval length over which it was computed.
Supplemental Opioid Use
Time Frame: 0 to 72 hours post-dose
Mean total morphine-equivalent dose during the period 0 to 72 hours post-dose
Secondary Outcomes
- Time-to-first Use of Opioid Supplemental Pain Medication(0 to 14 days post-dose)
- Number (Frequency) of Participants Reporting Opioid-related Adverse Events(0 to 72 hours post-dose)
- Supplemental Opioid Use(0 to 48 hours post-dose)
- Severity of Opioid-related Side Effects(0 to 14 days post-dose)
- Mean Pain Intensity on Movement AUC (Time-normalized AUC) During the Period 0 to 48 Hours Post-dose (0 to 2 Days Post-dose).(0 to 48 hours post-dose)
