Study Overview
Brief Summary
This is a Phase 2, randomized, double-blind, 2-part comparator- and placebo-controlled study to evaluate the safety, PK, and efficacy of TLC590 via a single infiltrative local administration in adult subjects following bunionectomy.
Detailed Description
This is a Phase 2, randomized, double-blind, 2-part comparator- and placebo-controlled study to evaluate the safety, PK, and efficacy of TLC590 via a single infiltrative local administration in adult subjects following bunionectomy.
The primary objective of this study is to evaluate the analgesic efficacy of TLC590 for post-surgical pain management in subjects following bunionectomy.
The secondary objectives of this study are:
- To evaluate the pharmacokinetic (PK) profile and dose-exposure relationship of TLC590, as well as the bioavailability as compared with Naropin®.
- To evaluate the safety and tolerability of TLC590 for post-surgical pain management in subjects following bunionectomy.
- To evaluate the exposure-response relationship between PK parameters and pain intensity.
The study will be divided into two parts:
