Brief Summary:
This is the first time HTL0014242 will be administered to humans. The principal aim of this study is to obtain safety and tolerability data when HTL0014242 is administered orally as single doses to healthy subjects. This information, together with the pharmacokinetics data, will help establish the doses and dosing regimen suitable for future studies in patients

Condition or disease Intervention/treatment Phase
Healthy Drug: HTL0014242 Drug: Placebo oral capsule Phase 1

Detailed Description:

This study will comprise a single dose, sequential group design. Overall, 48 subjects will be studied in 6 planned groups (Groups 1 to 6), with each group consisting of 8 subjects.

Subjects will be screened within 28 days prior to dosing. Each subject will participate in 1 treatment period only. Subjects will reside at the clinical research unit from Day -1 (the day before dosing) to Day 5.

All subjects will return for a follow-up visit 7 to 14 days after dosing. The investigator (or designee) may also request that the subject return for an additional follow up visit.

In each of groups 1 to 6, 6 subjects will receive a single dose of HTL0014242 and 2 subjects will receive placebo oral capsule in accordance with a randomisation schedule.
