Eligibility
Key inclusion criteria
Each subject must meet all of the following criteria to be enrolled in this study:

1. Male and female subjects must be 18 years or older.
2. Subjects must be willing to provide written informed consent to participate in the study.
3. Subjects must be in generally good health as determined by pre-study medical history, physical examination, clinical laboratory tests, and 12 lead ECG measurements.
4. Subjects must be willing to remain in confinement at the clinical study unit for up to 8.5 consecutive days and to return to the unit as specified for additional blood tests and safety evaluations during the study period.
5. Subjects must have a body mass index (BMI) of 19-32 kg/m2. Participants with a BMI below 19 kg/m2 may be enrolled at the Investigator's discretion.
6. Subjects must have a systolic blood pressure (BP) of 90-160 mmHg, diastolic BP of 50-90 mmHg, and resting HR of 40-100 beats per min without medication at Screening.
7. Subjects must have clinical chemistry values for electrolytes, alkaline phosphatase (ALP), alanine aminotransferase (ALT <1.5x ULN), aspartate aminotransferase (AST, <1.5x ULN), lactate dehydrogenase (LDH), creatine phosphokinase (CPK), creatinine, bilirubin (<2x ULN), and urea that are within the normal range without medication or not clinically significant for a healthy population in the opinion of the Investigator at Screening. Renal clearance measured by eGFR must be normal (=80 mL/min). Urinalysis values must be within normal limits or not clinically significant for a healthy population in the opinion of the Investigator at Screening. Laboratory analyses and urinalysis may be repeated once at the Investigator's discretion to confirm the accuracy of the results.
8. Subjects must have an early morning (drawn seated between 0600 am and 0800 am) serum cortisol level >5 mcg/dL (>137.9 nmol/L) and early morning adrenocorticotropic hormone (ACTH) and aldosterone levels within the normal range at screening. Randomization will be conditional to a normal cortisol response to ACTH stimulation during screening [serum cortisol level =16 mcg/dL (=440 nmol/L) after IM ACTH injection].
9. Subjects must be non-smokers or previous smokers who have not smoked within the previous 6 months prior to Screening.
10. Male participants must use, from randomization until at least 2 months after the last dose, a highly effective contraception method (less than 1 pregnancy per 100 people using the method for one year), e.g.: sterilisation (e.g., vasectomy), and/or barrier forms of contraception, including condoms (external or internal) and diaphragm ('cap').
11. Male subjects must not donate sperm during the study and for 12 months after receiving the last dose of study drug.
12. Female subjects must be non-pregnant, non-lactating, and either postmenopausal for at least 1 year, or surgically sterile (bilateral tubal ligation ('clipping or tying tubes' or hysterectomy) for at least 3 months, or they must agree to use a highly effective contraception method (less than 1 pregnancy per 100 people using the method for one year), from 28 days and/or their last confirmed menstrual period prior to study enrollment (whichever is longer) until 2 months after clinic discharge. Highly effective contraception methods include: Intra-uterine device (IUD) containing either copper or levonorgestrel (e.g., Mirena®), and/or barrier methods of contraception, including condoms (external or internal) and diaphragm ('cap'). Hormonal methods of contraception (with the exception of hormonal IUD) are not permitted within this study. Female participants will refrain from using hormonal contraceptives for at least 28 days prior to study entry until the end of the study period. Participants/Participant's partner(s) must also use a barrier form of contraception, from the first dose of study drug through until 2 months after the last dose. For all females of childbearing potential, the pregnancy test result must be negative at Screening and Pre-Study Baseline (Day -1).

8. Subjects who have used (within 30 days of randomization) or plan on using during the duration of the study any dietary aids, supplements, or foods that are known to modulate drug metabolizing enzymes (e.g., St. John's wort, grapefruit juice).
9. Subjects with difficulty in swallowing oral medications.
10. Subjects with serious psychosocial comorbidities as determined by the Investigator.
11. Subjects with current cognitive or major psychiatric disorders, or any other condition that could interfere with compliance with study procedures and/or confinement in a clinical study unit for up to 8.5 days.
12. Subjects with a positive drug or alcohol test during Screening and/or admission (a positive THC test will be allowed as long as it consists of minimal social use, per discretion of Investigator).
13. Subjects who have used any other investigational drug within 1 month prior to Screening.
14. Subjects who have used any over-the-counter medications within 2 weeks of randomization, or paracetamol or ibuprofen within 7 days of randomization

19. Subjects with confirmed COVID-19, or suspected COVID-19 (e.g., developed symptoms of a respiratory infection such as cough, sore throat, shortness of breath, or fever, but did not get tested for COVID-19) at the time of Screening.
20. Subjects with confirmed moderate-severe COVID-19 within 2 months of randomization or with confirmed asymptomatic or mild COVID-19 within 4 weeks of randomization.
21. Subjects who have received a COVID-19 vaccine within 4 weeks of randomization or are planning on receiving it during the study duration.
