Description
Inclusion Criteria:
- Male or non-childbearing potential female, non-smoker (no use of tobacco or nicotine products within 3 months prior to screening), ≥ 18 and ≤ 50 years of age, with BMI > 18.0 and < 30.0 kg/m2 and body weight ≥ 50.0 kg for males and ≥ 45.0 kg for females.
Healthy as defined by:
- The absence of clinically significant illness and surgery within 4 weeks prior to the first dosing. Subjects vomiting within 24 hours pre-dose will be carefully evaluated for upcoming illness/disease. Inclusion pre-dosing is at the discretion of the Investigator.
- The absence of clinically significant history of neurological, endocrine, cardiovascular, respiratory, hematological, immunological, psychiatric, gastrointestinal, renal, hepatic, and metabolic disease.
Non-childbearing potential female is defined as:

or
- Surgically sterile female (hysterectomy or tubal ligation at least 6 months prior to drug administration).
Male subjects who have not been vasectomized for at least 6 months prior, and who are sexually active with a female partner of childbearing potential (childbearing potential females are defined as women that are neither post-menopausal nor surgically sterile) must be willing to use one of the following acceptable contraceptive methods from the first study drug administration until at least 90 days after the last study drug administration:
- Simultaneous use of a male condom and, for the female partner, hormonal contraceptives used since at least 4 weeks prior or intra-uterine contraceptive device placed since at least 4 weeks prior;
- Simultaneous use of a male condom and, for the female partner, a diaphragm or cervical cap with intravaginally applied spermicide.
- Male subjects (including men who have had a vasectomy) with a pregnant partner must agree to use a condom from the first study drug administration until at least 90 days after the last study drug administration.
- Male subjects must be willing not to donate sperm until 90 days following the last study drug administration.
- Capable of consent.
Exclusion Criteria:
- Any clinically significant abnormality at physical examination, clinically significant abnormal laboratory test results or positive test for hepatitis B, hepatitis C, or HIV found during medical screening.
- Positive urine drug screen, alcohol breath test, or urine cotinine test at screening.
- History of allergic reactions to TBN or other related drugs, or to any excipient in the formulation.
- Positive pregnancy test at screening.
- Clinically significant ECG abnormalities or vital sign abnormalities, systolic BP lower than 90 or over 140 mmHg, diastolic BP lower than 50 or over 90 mmHg, or HR less than 50 or over 100 bpm; orthostatic BP: decrease in systolic BP of 20 mmHg or higher, decrease in diastolic BP of 10 mmHg or higher, or increase in HR of 30 bpm or higher within 2 to 3 minutes after passing from a supine to a standing position at screening.
- History of significant alcohol abuse within 1 year prior to screening or regular use of alcohol within 6 months prior to the screening visit (more than 14 units of alcohol per week [1 unit = 150 mL of wine, 360 mL of beer, or 45 mL of 40% alcohol]).
- History of significant drug abuse within 1 year prior to screening or use of soft drugs (such as marijuana) within 3 months prior to the screening visit or hard drugs (such as cocaine, PCP, crack, opioid derivatives including heroin, and amphetamine derivatives) within 1 year prior to screening.
- Participation in a clinical research study involving the administration of an investigational or marketed drug or device within 30 days prior to the first dosing, administration of a biological product in the context of a clinical research study within 90 days prior to the first dosing, or concomitant participation in an investigational study involving no drug or device administration.
Use of medications for the timeframes specified below, with the exception of medications exempted by the Investigator on a case-by-case basis because they are judged unlikely to affect the PK profile of the study drug or subject safety (e.g., topical drug products without significant systemic absorption):
- Prescription medications within 14 days prior to the first dosing;
- Over-the-counter products and natural health products (including herbal remedies, homeopathic and traditional medicines, probiotics, food supplements such as vitamins, minerals, amino acids, essential fatty acids, and protein supplements used in sports) within 7 days prior to the first dosing, with the exception of the occasional use of acetaminophen (up to 2 g daily);

- Any drugs known to induce or inhibit hepatic drug metabolism (including St. John's wort) within 30 days prior to the first dosing.
- Donation of plasma within 7 days prior to dosing. Donation or loss of blood (excluding volume drawn at screening) of 50 mL to 499 mL of blood within 30 days, or more than 499 mL within 56 days prior to the first dosing.
- Any reason which, in the opinion of the Investigator, would prevent the subject from participating in the study.
- Breast-feeding subject.
- Any history of thyroid/gland abnormalities.
- Any history of suicidal ideation or suicidal behavior (within 2 years prior to screening), as assessed by the C-SSRS (baseline version).
