Brief summary

Phase I/II, randomized, double-blind, comparator-controlled, dose-escalation study to assess the safety, PK, and efficacy of single postsurgical application of TLC590 compared with Naropin®

Detailed description

A Phase I/II, randomized, double-blind, comparator-controlled, dose-escalation study to assess the safety, PK, and efficacy of single postsurgical application of TLC590 compared with Naropin® via a single infiltrative local administration in adult subjects following inguinal hernia repair surgery. Approximately 64 evaluable subjects across 4 cohorts. Dose escalation of a single postsurgical administration of TLC590 or Naropin® will be performed. Dose escalation will be determined by review of treatment-related adverse events and all serious adverse events (AEs) by a safety monitoring committee.

QUADRUPLE (Subject, Caregiver, Investigator, Outcomes Assessor)

Masking description

To maintain objectiveness, the study drug will be managed and administered by an independent unblinded team. Subjects, investigators, and all other site staff who directly interact with subjects, evaluate safety and efficacy, and collect subject data, will remain blinded and must not communicate or discuss any study information with the unblinded team.

Intervention model description

Subjects will be enrolled to each cohort in a 3:1 ratio. Each cohort will comprise subjects receiving a dose of TLC590 and active comparator drug (Naropin® 150 mg) in accordance with the randomization schedule and dose-escalation scheme.
