Brief Summary

This is a phase 1 single-center study to assess the pharmacokinetics (PK), safety and tolerability of KT07 capsules in healthy adult subjects. This study consists of 2 parts: Part 1 and Part 2.

The primary objectives of Part 1 include selection of suitable PK markers for bioanalysis, development and validation of GLP bioanalytical methods for follow-up PK studies, assessment of PK of potential markers following an oral administration of KT07, and provision of PK sampling strategy for Part 2.

The primary objective of Part 2 is to evaluate the PK profile following a single dose and multiple doses in healthy adult subjects.

Detailed Description

This is a 2-part PK study. Each Part consists of 3 phases: a 2-week screening phase, drug administration and PK sampling phase, then a safety follow-up visit at Day 7 after the last dose. Subjects enter screening at Visit 1.

Part 1: Pilot single-dose PK Study Part 1 is an open-label study. Six (6) eligible male adult healthy volunteers aged between 18 to 65 years will receive a single oral dose of KT07 capsules on Day 1.

Part 2: Single and multiple-dose PK Study A total of 20 healthy subjects will participate in this part of the study, which consists of 2 cohorts with 10 subjects each. Subjects will receive either active treatment or placebo treatment in each cohort in a double-blind manner to evaluate PK and safety of KT07.
