简要总结
The purpose of this study is to evaluate the safety and pharmacokinetics of redosing EXPAREL via local subcutaneous infiltration in healthy volunteers.
详细描述
During Dosing Period 1, blood samples for pharmacokinetic (PK) analysis will be obtained predose (15 minutes prior to administration of EXPAREL) through 12 hours postdose (i.e., at 15 and 30 minutes, 1, 2, 4, 8, and 12 hours) for Cohort 4; through 36 hours postdose (i.e., at 15 and 30 minutes, 1, 2, 4, 8, 12, 24, and 36 hours) for Cohort 3; through 60 hours postdose (i.e., at 15 and 30 minutes, 1, 2, 4, 8, 12, 24, 36, 48, and 60 hours) for Cohort 2; and through 72 hours postdose (i.e., at 15 and 30 minutes, 1, 2, 4, 8, 12, 24, 36, 48, 60, and 72 hours) for Cohorts 1 and 5.
During Dosing Period 2 (Cohorts 2, 3, and 4 only), blood samples for PK analysis will be obtained predose (15 minutes prior to administration of EXPAREL) through 72 hours postdose (i.e., at 15 and 30 minutes, 1, 2, 4, 8, 12, 24, 36, 48, 60, and 72 hours).

- •History of abnormal bleeding tendencies/clotting disorders.
- •Regular use of anticoagulants (except for low dose aspirin for cardioprotection).
- •Received any investigational drug within 30 days prior to study drug administration, and/or has planned administration of another investigational product or procedure during his/her participation in this study.
- •Currently pregnant, nursing, or planning to become pregnant during the study or within 1 month after study drug administration.
- •Subjects with significant medical conditions or laboratory results that, in the opinion of the Investigator, would constitute a contraindication to participation in the study, or cause inability to comply with the study requirements.
