Inclusion Criteria:
- Male or female >=40 and <=80 years of age at the time of signing the informed consent.
- A female subject is eligible to participate if she is of:
Non-childbearing potential defined as premenopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone >40 milli international unit per milliliter (mIU/mL) and oestradiol <40 picogram [pg]/mL [<147 picomole per liter (pmol/L)] is confirmatory); females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the contraception methods (i.e., in accordance with the approved product label and the instructions of the physician for the duration of the study from Screening to follow-up contact) if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrolment. For most forms of HRT, at least 2 to 4 weeks should elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. After confirmation of their postmenopausal status, they can resume use of HRT during the study without use of a contraceptive method; child-bearing potential and is abstinent or agrees to use one of the contraception methods for an appropriate period of time (as determined by the product label or investigator) before the start of dosing to sufficiently minimise the risk of pregnancy at that point. Female subjects must agree to use contraception until at least 2 days post the last dose of study treatment; abstinence from penile-vaginal intercourse must be consistent with the preferred and usual lifestyle of the subject.

- Oropharyngeal Examination: A subject will not be eligible for the Run-in Period if he/she has clinical visual evidence of candidiasis at Visit 1 (Screening and Run-in Visit)
- An abnormal and clinically significant 12-lead ECG result. For the purposes of this study, an abnormal ECG result is defined as a 12-lead tracing that is interpreted as demonstrating (but not limited to) any of the following: Myocardial ischemia, clinically significant conduction abnormalities (e.g., left bundle branch block, Wolff-Parkinson-White syndrome), clinically significant arrhythmias (e.g., atrial fibrillation, ventricular tachycardia). The study investigator will determine the clinical significance of any ECG abnormality and determine if a subject is precluded from entering the study.
