Study in Pediatric Subjects Evaluating Pharmacokinetics and Safety of EXPAREL

Phase 1

Completed

• Conditions: Postoperative Pain Management
• Interventions: Drug: Exparel

• Registration Number: NCT03485014
• Lead Sponsor: Pacira Pharmaceuticals, Inc

Brief Summary

Primary objective: The primary objective of this study is to evaluate the pharmacokinetics (PK) of EXPAREL in pediatric subjects 12 to less than 17 years of age undergoing spinal surgery.

Secondary objective: The secondary objective of this study is to evaluate the safety of EXPAREL in pediatric subjects 12 to less than 17 years of age undergoing spinal surgery.

Detailed Description

This is a Phase 1, single-center, open-label study designed to evaluate the safety and PK profile of EXAPREL when administered intraoperatively at the end of surgery via local infiltration. Fifteen pediatric subjects 12 to less than 17 years of age undergoing spinal surgeries are planned for enrollment.

Subjects will be screened within 30 days prior to study drug administration. During the screening visit, subjects will be assessed for past or present neurologic, cardiac, and general medical conditions that, in the opinion of the investigator, would preclude them from study participation.

Subjects will undergo their pre-planned spinal surgeries per the institution's standard of care. On Day 1, eligible subjects will receive a single dose of EXPAREL 4 mg/kg intraoperatively at the end of surgery via local infiltration into the surgical site. There is no required length of stay in the hospital; subjects may be discharged based on the medical judgment of the treating physician.

A follow-up phone call will be scheduled for all subjects on Day 7. A final follow-up visit will be made on Day 30 to all subjects who received study drug.

2. Administration of EXPAREL or bupivacaine HCl within 30 days prior to study drug administration.

3. Subjects with coagulopathies or immunodeficiency disorders.

4. Administration of an investigational drug within 30 days or 5 elimination half-lives of such investigational drug, whichever is longer, prior to study drug administration, or planned administration of another investigational product or procedure during the subject's participation in this study.
