A Study to Evaluate if AC-084 is Safe, Its Fate in the Body as Well as Its Potential Effects on the Body in Healthy Subjects

A Three-part Single-center, Phase 1 Study to Assess the Tolerability, Safety, Pharmacokinetics (Including Food Interaction), and Pharmacodynamics of Ascending Single and Multiple Doses of AC-084 in Healthy Subjects and to Investigate the Pharmacokinetics of a Single Dose of AC-084 in Healthy CYP2C9 Poor Metabolizers

Brief summary

The primary purpose of this first-in-man study is to investigate whether AC-084 is safe and well-tolerated when orally administered at single- and multiple-ascending dose to healthy adults

Detailed description

The study is designed in three parts, A, B and C Part A: single-center, double-blind, randomized, placebo-controlled, single ascending dose Part B: single-center, double-blind, randomized, placebo-controlled, multiple ascending dose Part C: single-center, open-label, single dose in CYP2C9 poor metabolizers

Interventions

DRUGAC-084

Hard gelatin capsules for oral administration formulated in strengths of 1 mg, 10 mg, and 100 mg

DRUGPlacebo

Placebo capsules matching AC-084 capsules

Inclusion criteria

* Signed informed consent in the local language prior to any study-mandated procedure * Healthy male subjects for Part A, healthy male and female subjects for Part B and Part C aged between 18 and 55 years (inclusive) at screening * No clinically significant findings on physical examination at screening * Body mass index (BMI) of 18.0 to 28.0 kg/m2 (inclusive) at screening * CYP2C9 poor metabolizers (Part C)

Exclusion criteria

* History or clinical evidence of any disease and/or existence of any surgical or medical condition that might interfere with the absorption, distribution, metabolism or excretion of the study treatment (appendectomy and herniotomy allowed, cholecystectomy not allowed) * Previous history of fainting, collapse, syncope, orthostatic hypotension, or vasovagal reactions * Treatment or substances known to induce CYP enzyme drug metabolism within 30 days prior to first study treatment administration * Any circumstances or conditions, which, in the opinion of the investigator, may affect full participation in the study or compliance with the protocol * Known allergic reactions or hypersensitivity to the study treatment or drugs of the same class, or any of their excipients * For Part A and Part B, CYP2C9 poor metabolizers enrolled in a cohort to be dosed with single or multiple dose of 500 mg or higher of ACT-774312 (confirmed by genotyping before enrollment)
