Safety, Tolerability, and Pharmacokinetics, of Single and Multiple Ascending Doses of FP-020 in Healthy Adult Volunteers

1. Subject must be ≥ 18 years and ≤ 60 years of age at the time of signing informed consent.
2. Subjects must be in good general health in the opinion of the Investigator, with no significant medical history, no clinically significant abnormalities on physical examination, vital signs, ECG, and laboratory safety tests performed at Screening and/or before administration of the first dose of study drug.
3. Clinical laboratory test values within normal ranges or \< 1.5 times the upper limit of normal (ULN) as specified by the testing laboratory unless deemed not clinically significant (NCS) by the Investigator, with the exception of bilirubin as described below.
4. Nonsmoker or ex-smoker who has discontinued smoking and/or use of nicotine containing products for at least 6 months prior to the first dose of study drug, confirmed by a negative cotinine test at Screening and Day -1. Note however that casual smoking (e.g., 5 cigarettes [or equivalent] per week) is permitted during that period (i.e., within 3 months prior to dosing) as long as the cotinine test on Day 1 is negative.
5. Ability to communicate well with the Investigator, in the local language, and to understand and comply with the requirements of the study.
6. Body mass index (BMI) within the range 18 to 32 kg/m2 (inclusive).
7. Females of childbearing potential and not abstinent must be willing to use a double barrier contraceptive method (progesterone-only hormone contraceptive [oral, injectable, implantable], intrauterine device [IUD], diaphragm, cervical cap, contraceptive sponge, condom) and refrain from oocyte donation from screening to 30 days after the last dose of study intervention. Estrogen-containing products are not allowed. Females who are abstinent are not required to use a contraceptive method unless they become sexually active. Alternatively, females must be postmenopausal for ≥1 year or surgically sterile (with tubal ligation, hysterectomy, or bilateral oophorectomy) for ≥6 months, confirmed by FSH level >40mIU at Screening. Note that females on HRT are not eligible.
8. Males with female partners of childbearing potential will agree to use barrier contraceptive (i.e., condom) and their female partners must use a highly effective method of contraception from screening to 90 days after the last dose of study drug. Males must also refrain from sperm donations during this time period. Males who are abstinent will not be required to use a contraceptive method unless they become sexually active.
9. Subjects capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.

Exclusion Criteria:

1. Recent (less than 6 weeks) wound, or presence of an ongoing non-healing skin wound.
2. Presence of any underlying physical or psychological medical condition that, in the opinion of the Investigator, would significantly alter the absorption, metabolism, or elimination of drugs; constitute a risk when taking the study intervention; interfere with the interpretation of data; or would make it unlikely that the subject will complete the study per protocol.
3. Active malignancy and/or history of malignancy in the past 5 years, with the exception of completely excised non-melanoma skin cancer or low grade cervical intraepithelial neoplasia.
4. Serious local or systemic infection within 1 month of Screening requiring antibiotic treatment or history of recurrent infections.
5. Surgery within the past 3 months prior to the first dose of study drug administration determined by the Investigator to be clinically relevant.
6. The subject has a history of severe drug allergy or hypersensitivity or food allergy, including anaphylaxis.
7. The subject has donated more than 1 unit (500 mL) of blood within 4 weeks prior to the first dose of study drug.
8. Positive for human immunodeficiency virus (HIV) antibody or antigen.
9. Positive hepatitis C virus (HCV) antibody or positive hepatitis B surface antigen (HBsAg).
10. Positive urine drug screen/alcohol breath test on Day -1 (admission). Repeat urine drug screens will be permitted for suspected false positive results.
11. Positive COVID-19 test (conducted as per institutional guidelines).
12. Abnormal vital signs (resting heart rate \< 40 or > 100 bpm; resting systolic blood pressure >150 or \< 90 mmHg or diastolic blood pressure > 90 or \< 50 mmHg) at Screening or before administration of the first dose of study drug.
13. Any other abnormal vital signs that are considered to be clinically significant by the Investigator.
14. QTcF interval (QT with Fridericia's correction) > 450 msec in males and > 470 msec in females (based on the mean of triplicate measurements taken at screening), cardiac arrhythmia, or any clinically significant abnormality in the resting ECG as deemed by the Investigator.
15. Females with heavy menstruating cycles and borderline-low iron studies.
16. Alanine transaminase (ALT) or aspartate aminotransferase (AST) >1.5 upper limit of normal.
17. Bilirubin outside of the normal range (total bilirubin between 0.1 and 1.2 mg/dL (1.71 to 20.5 µmol/L).
18. Creatinine clearance \< 90 mL/min (estimated from Cockcroft Gault equation).
19. Subject is pregnant, lactating, or is planning to become pregnant during the study.
20. Inability to tolerate oral medications.
21. All prescription and over-the-counter medications (including herbal medications) except for non-estrogen contraceptives, are prohibited within 7 days before dosing through EOS.
22. Any estrogen-containing products, e.g., contraceptives, patches, creams, implants, within 14 days prior to administration of the first dose of study drug through EOS.
23. Live vaccine(s) within 1 month before Screening or plans to receive such vaccines during the study.
24. Treatment with biologic agents (such as monoclonal antibodies including marketed drugs) within 3 months or 5 half-lives (whichever is longer) before dosing.
25. Current participation in any other investigational drug study or receipt of an investigational drug within 30 days or 5 half-lives (whichever is longer) before dosing.
26. Significant weight loss or gain between Screening and administration of first dose of study drug.
27. Blood donation or significant blood loss within 60 days prior to administration of first dose of study drug.
28. Plasma donation within 7 days prior to administration of first dose of study drug.
29. Diets that could alter metabolism (i.e., high protein, Slim Fast®, Nutrisystem®, etc.) within 7 days prior to administration of first dose of study drug.
30. History or presence of alcohol or drug abuse (including recreational marijuana use) within 1 year prior to administration of first dose of study drug and unwillingness to abstain during the dosing period.
31. Intake of alcohol or caffeine-containing products 48 hours before administration of first dose of study drug.
32. Use of tobacco products (e.g., cigarettes, e-cigarettes, cigars, smokeless tobacco) confirmed by a positive cotinine test on Day -1.
33. Failure to satisfy the Investigator of fitness to participate for any other reason.
