Pilot Herniorrhaphy Study for Postoperative Analgesia

This study includes multiple formulations for formulation selection of the fixed-combination product and for the factorial design assessment of the contribution of each component. HTX-011 is the initial formulation studied (HTX-011-19). HTX-011A is the second formulation studied (HTX-011-49). HTX-011B is the final formulation studied (HTX-011-56), which was also included in subsequent Phase 2b and Phase 3 studies. For the factorial design assessment, HTX-002, a bupivacaine-only formulation in the same HTX-011 proprietary polymer, and HTX-009, a meloxicam-only formulation in the same HTX-011 proprietary polymer, were evaluated.
