A Study of Single and Multiple Oral Doses of TollB-001

Toll Biotech Co. Ltd. (Beijing)122 enrolled

Overview

The primary objective is to evaluate the safety and tolerability of TollB-001 following the administration of single or multiple oral doses in healthy adult subjects

This is a Phase I, randomized, double-blind, placebo-controlled study to evaluate the safety, tolerability, PK, and PD of single or multiple dose(s) of TollB-001 administered orally in healthy adult subjects and the food effect on the PK of a single dose of TollB-001 with a randomized, open-label and two-period crossover design. This study includes three parts. Part A: single ascending dose (SAD) study; Part B: multiple ascending dose (MAD) study; and Part C: FE study.
