  3. Female subject with a negative pregnancy test at screening and admission.
  4. Male subject (and partner of childbearing potential) willing to use a highly effective method of contraception or 2 effective methods of contraception, if applicable (unless anatomically sterile or where abstaining from sexual intercourse is in line with the preferred and usual lifestyle of the subject) from first dose until 3 months after last dose of the investigation medicinal product (IMP).
  5. Male subjects (including men who have had vasectomies) with a pregnant partner must agree to use a condom from first dose until at least 3 months (90 days) after last dose of IMP.
  6. Male subjects must be willing to not donate sperm until 3 months (90 days) following last dose of IMP.
  7. Subject with a body mass index (BMI) of >18.5 and <30 kg/m2 and body weight ≥50.0 kg for males and ≥45.0 kg for females (BMI = body weight (kg) / [height (m)]2), at screening.
  8. Healthy as defined by:

    1. Absence of clinically significant illness and surgery within 4 weeks prior to dosing. Subjects vomiting within 24 hours (h) pre-dose will be carefully evaluated for upcoming illness/disease. Inclusion pre-dosing is at the discretion of the PI.
    2. Absence of clinically significant history of neurological, endocrinal, cardiovascular, pulmonary, haematological, immunologic, psychiatric, gastrointestinal, renal, hepatic and metabolic disease.
  9. Continuous non-smoker who has not used tobacco or nicotine-containing products for at least 3 months prior to Screening and throughout the study, or users of cigarette replacements (i.e., e-cigarettes, nicotine patches or gums).
  10. No clinically significant history of previous allergy / sensitivity to PBI-4050 or any of the excipients contained within the IMP(s).

  22. Subjects with any special food restrictions that would hinder ability to consume the high fat breakfast provided during the study; e.g. vegetarian, lactose intolerance, vegan, low-fat, low sodium, and/or restrictions for medical, religious, social or cultural reasons, etc).
  23. Any reason which, in the opinion of the PI, would prevent the subject from participating in the study.
