Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: In each cohort, subjects will be randomized in a 2:1 ratio to HTX-011 or bupivacaine HCl, respectively. All subjects will receive a scheduled postoperative non opioid multimodal analgesic (MMA) regimen.
Primary purpose: TREATMENT

Brief summary: This is a Phase 4, randomized, blinded, active-controlled, multicohort study to evaluate HTX-011 compared with bupivacaine HCl in subjects undergoing abdominoplasty (Cohort 2).


Eligibility criteria: Inclusion Criteria:

* Has American Society of Anesthesiologists (ASA) Physical Status of I, II, or III.
* Is scheduled to undergo abdominoplasty.

Exclusion Criteria:

* Is undergoing a revision surgery.
* Has a known or suspected history of hypersensitivity or clinically significant idiosyncratic reaction to bupivacaine (or other local anesthetics), NSAIDs, acetaminophen, oxycodone, morphine, or hydromorphone.
* History of severe allergic reaction to aspirin or other NSAIDs, or known history of severe gastrointestinal adverse reactions associated with NSAID use.
* Has taken meloxicam within 10 days prior to the scheduled surgery, or any NSAID within 24 hours prior to the scheduled surgery, with the exception of subjects on low-dose (≤100 mg) daily acetylsalicylic acid for cardioprotection.
* Opioid use for most days within the last 3 months prior to Screening in the opinion of the Investigator.
* Has been administered immediate-release bupivacaine HCl within 5 days prior to the scheduled surgery, or a modified-release bupivacaine product within 14 days prior to the scheduled surgery.
* Has initiated treatment with any of the following medications within 1 month prior to study drug administration: selective serotonin reuptake inhibitors, selective norepinephrine reuptake inhibitors, gabapentin, pregabalin, duloxetine, or cyclooxygenase-2 inhibitors.
* Has been administered systemic steroids within 5 half-lives or 10 days prior to the scheduled surgery (whichever is longer).
* Has a known or suspected history of drug abuse, a positive drug screen (except for cannabinoids) on the day of surgery, or a history of alcohol abuse within the past 5 years.
* Suspected or confirmed active coronavirus disease 2019 (COVID-19) infection.
* Had a malignancy in the last year, with the exception of nonmetastatic basal cell or squamous cell carcinoma of the skin or localized carcinoma in situ of the cervix.
* Has undergone 3 or more surgeries within 12 months, other than for diagnostic procedures (eg, colonoscopy).
* Has a body mass index (BMI) \>40 kg/m2.
* Had undergone prior abdominoplasty or major abdominal wall surgery.
