Brief Summary

A Phase 1, Open-Label, Randomized, Single-Dose, Parallel-Group Study to Evaluate the Food Effect on the Pharmacokinetics of TP-05 under Fed and Fasted Conditions in Healthy Participants.

Detailed Description

This is a Phase 1, open-label, randomized, single-dose, parallel-group study to evaluate the food effect on the pharmacokinetics of TP-05 under fed and fasted conditions in healthy participants.

The study will consist of a screening period of up to 28 days. Participants who are eligible for the study will check into the clinical research site on Day -1. All participants will undergo an overnight fast of at least 10.5 hours prior to dosing. On Day -1 participants will be randomized to receive one of three treatment regimens on Day 1: single dose of TP-05, fasted; single dose of TP-05 following a high-fat breakfast; or single dose of TP-05 following a low-fat breakfast.

Participants will be resident at the clinical research site from Day -1 until completion of assessments at 96 hours post-dose (Day 5) and return on Day 60 for a follow-up visit. Participants will complete a telephone safety follow-up visit at Day 120.

Safety will be assessed by adverse events, vital signs, performing physical examinations, electrocardiograms, and evaluating clinical laboratory results.
