Primary Outcome Measures:
  • Duration of analgesia [ Time Frame: 10 days ] [ Designated as safety issue: No ]
    The primary outcome measure is the duration of analgesia, measured by the time from the end surgery to the subject's first postsurgical opioid administration.


Secondary Outcome Measures:
  • Efficacy measures of EXPAREL. [ Time Frame: 10 days ] [ Designated as safety issue: No ]

    Postsurgical assessments will include:

    • Date, time, amount, and route of all opioid and non-opioid analgesics administered in the surgical center.
    • Subject's assessment of pain intensity using a numeric rating scale (NRS) upon waking in the post-anesthesia care unit (PACU) and at time of hospital discharge
    • Date and time the hospital discharge order is written.
    • Overall subject satisfaction with postsurgical pain control (using a 5-point Likert scale) at the time of hospital discharge and at the Day 10 visit.

  • Safety Assessment [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
    Postsurgical safety assessments will include adverse events (AEs) and serious adverse events (SAEs).

Arms Assigned Interventions
Active Comparator: Infiltration - EXPAREL
Group 2 will receive diluted EXPAREL (i.e., the contents of one 20 mL vial, 266 mg, diluted with 20 mL of preservative-free 0.9% normal saline to a total of 40 mL) for postsurgical analgesia. Half of the resulting mixture (i.e., 20 mL) will be administered via local infiltration into each surgical site per the surgeon's normal practice at the beginning of surgery.
Drug: Instillation - EXPAREL
Intravenous (IV) morphine sulfate, hydromorphone, or oral oxycodone with acetaminophen (5/325 mg) will be permitted following surgery, as needed.
Other Name: bupivacaine liposomal injectable suspension
Experimental: Instillation - EXPAREL
Group 1 will receive diluted EXPAREL (i.e., the contents of one 20 mL vial, 266 mg, diluted with 20 mL of preservative-free 0.9% normal saline to a total of 40 mL) for postsurgical analgesia. Half of the resulting mixture (i.e., 20 mL) will be instilled into each breast pocket at the beginning of surgery.
Drug: Infiltration - EXPAREL
IV morphine sulfate, hydromorphone, or oral oxycodone with acetaminophen (5/325 mg) will be permitted following surgery, as needed.
Other Name: bupivacaine liposomal injectable suspension

Detailed Description:

Each subject will undergo bilateral augmentation mammoplasty and will receive the same dose of EXPAREL. This primary objective of this study is to assess the efficacy of EXPAREL when administered via infiltration versus instillation as part of bilateral augmentation mammoplasty. The secondary objectives are to further assess other efficacy measures and the safety profile of EXPAREL.

  Eligibility

Ages Eligible for Study:   18 Years to 75 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Female, 18-75 years of age inclusive.
  • American Society of Anesthesiologists (ASA) physical status 1-3.
  • Undergoing bilateral augmentation mammoplasty without any concurrent surgical procedure(s).
  • Physically and mentally able to participate in the study and complete all study assessments.
  • Able to give fully informed consent to participate in this study after demonstrating a good understanding of the risks and benefits of the study components.

Exclusion Criteria:

  • History of hypersensitivity or idiosyncratic reactions to amide-type local anesthetics.
  • Any subject whose anatomy or surgical procedure might, in the opinion of the Investigator, preclude the potential successful local administration of EXPAREL.
  • Subjects currently pregnant or who may become pregnant during the course of the study.
  • Any subject who in the opinion of the Investigator might be harmed or be a poor candidate for participation in the study.
  • Subjects who have received any investigational drug within 30 days prior to study drug administration, or planned administration of another investigational product or procedure during their participation in this study.
