A Prospective Study to Compare Bupivacaine and Exparel Versus Bupivacaine or Exparel Alone for Postoperative Pain Relief

Study Purpose

The purpose of this study is to collect information about how patients feel when doctors manage their pain after lumbar spine surgery using a combination of EXPAREL® and bupivacaine injected into the lumbar spine at the end of surgery, compared to the patients that doctors use only EXPAREL® or bupivacaine to manage their pain. This information will help doctors determine which approach works best for patients who will receive surgery in their lumbar spine in the future.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
