About
This is a randomized, placebo-controlled, double-blind, 3-way crossover phase I study being conducted on healthy volunteers to investigate the effect of single dose of AZD6094 (600 mg) on cardiac repolarization under well-controlled conditions in accordance with the International Council for Harmonization (ICH) E14 guidelines. An open-label Moxifloxacin (400 mg), a fluoroquinolone broad spectrum antibiotic will be used as a appositive control for the time between the start of the Q wave and the end of the T wave (QT) prolongation in accordance with ICH E14 guidelines, to establish assay sensitivity. The core study consists of screening period, 3 treatment period (AZD6094, placebo and moxifloxacin; with a minimum washout period of 14 days between each treatment period) and follow-up. The study drugs will be administered orally. The study is planned to determine effect of AZD6094 at therapeutic dose, safety and tolerability. This study provides adequate and well-controlled mechanisms to deal with potential bias, facilitate identification of effects related to investigational product (IMP) administration and tolerability issues.
Full description
The study is planned to include approximately 45 healthy non-Japanese vasectomized male participants aged 18 to 55 years (inclusive) or male participants over 40 (and up to 55) years old not intending to father children will be enrolled. The study consists of 5 visits comprised of 3 treatment periods with 6 treatment sequences and will have a minimum washout period of 14 days between each treatment period.
Visit 1: Screening period (28 days) - Assessments done on Day -1 of treatment period 1.
Visits 2 to 4: 3 Treatment periods - Participants will be resident form day before IMP (single oral dose of AZD6094 (600 mg) tablet/AZD6094 matching placebo/moxifloxacin (400 mg) capsule) dosing (Day -1) until at least 48 hours post-dose and will be discharged on Day 3.
Visit 5: Follow-up - Participants will have clinical visit 14 days after discharge from the treatment period 3.
Participants will be randomized to 6 treatment sequences (ABC, ACB, BAC, BCA, CAB and CBA). In each sequence, participants will receive single oral dose of all 3 treatments (A - AZD6094 600 mg (3X 200 mg tablet), B - Placebo tablet, C - Moxifloxacin 400 mg capsule) with a washout period (14 days) between each treatment period.
The study duration will be approximately 84 days.

Inclusion criteria
Participants must fulfill the following criteria:
- Provision of signed and dated, written informed consent prior to any study specific procedure.
- Healthy vasectomized male participants with suitable veins for cannulation or repeated venipuncture, non-Japanese vasectomized male participants aged 18 to 55 years (inclusive) or male participants over 40 (and up to 55) years old not intending to father children.
- Body mass index (BMI) between 18 and 30 kg/m2 inclusive and weigh greater than 50 kg and no more than 100 kg.
- Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBL) less than or equal to the upper limit of normal for the institution.
- Have a calculated creatinine clearance (CrCL) greater than 80 mL/min using the Cockcroft-Gault formula at Screening.
- Provision of signed, written and dated informed consent for optional genetic/biomarker research. If a subject declines to participate in the genetic component of the study, there will be no penalty or loss of benefit to the subject. The subject will not be excluded from other aspects of the study described in this Clinical Study Protocol (CSP).
Exclusion criteria
Participants must not be randomized if any of the following exclusion criteria are fulfilled:
-
Healthy participants of Japanese ethnicity and any healthy subject that has 1 parent or grandparent (maternal or paternal) that is Japanese.
-
History of any clinically important disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
-
History or presence of gastrointestinal (GI), hepatic or renal disease or any other condition known to interfere with absorption, distribution, metabolism or excretion of drugs.
-
Any clinically important illness, medical/surgical procedure or trauma within 4 weeks of the first administration of IMP.
-
Planned in-patient surgery, dental procedure or hospitalization during the study.
-
Any clinically important abnormalities in clinical chemistry, hematology or urinalysis results as judged by the Investigator.
-
Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody and human immunodeficiency virus (HIV).
-
Abnormal vital signs, after 10 minutes supine rest, defined as any of the following:
- SBP < 90 mmHg or ≥ 140 mmHg; DBP < 50 mmHg or ≥ 90 mmHg; HR < 45 or > 85 beats per minute.
-
Any clinically important abnormalities in rhythm, conduction or morphology of the 12-lead resting ECG that may interfere with the interpretation of QTc interval changes. These include healthy participants with any of the following:
- Abnormal ST-T-wave morphology, particularly in the protocol defined primary lead (V2) or left ventricular hypertrophy.
- PR interval shortening < 120 ms (PR > 110 ms but < 120 ms is acceptable if there is no evidence of ventricular pre-excitation).
- PR interval prolongation (> 200 ms). Intermittent second (Type 1 second degree block [Wenckebach Phenomenon] while asleep is not exclusive]) or third degree atrioventricular (AV) block, or AV dissociation.
- Persistent or intermittent complete bundle branch block (BBB), incomplete bundle branch block (IBBB), or intraventricular conduction delay (IVCD) with QRS > 110 ms. Participants with QRS > 110 ms but < 115 ms are acceptable if there is no evidence of e.g. ventricular hypertrophy or pre-excitation.
- Prolonged QTcF > 450 ms or shortened QTcF < 340 ms or family history of long QT syndrome.
-
A history of additional risk factors for torsades de pointes (TdP) (e.g., heart failure, hypokalemia, family history of long QT syndrome or sudden death at young age).
