Criteria

Inclusion Criteria:

• Age : 18 to 65 years, inclusive, at screening

• Weight : 50 to 110 kg, inclusive, at screening

• Body mass index : 18.0 to 30.0 kg/m2, inclusive, at screening

• At screening, females can be of childbearing potential (but not pregnant or lactating), or of nonchildbearing potential (either surgically sterilized or physiologically incapable of becoming pregnant, or at least 1 year postmenopausal [amenorrhea duration of 12 consecutive months]); nonpregnancy will be confirmed for all females by a negative serum pregnancy test at screening, (each) admission, and follow-up.

• Female subjects of childbearing potential who have a fertile male sexual partner must agree to use adequate contraception from at least 4 weeks prior to (first) administration of the study drug until 90 days after the follow up visit. Adequate contraception is defined as using hormonal contraceptives or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm, a cervical cap, or a condom. Total abstinence from heterosexual intercourse, in accordance with the lifestyle of the subject, is also acceptable.

• Male subjects, if not surgically sterilized, must agree to use adequate contraception and not donate sperm from (first) admission to the clinical research center until 90 days after the follow-up visit. Adequate contraception for the male subject (and his female partner, if she is of childbearing potential) is defined as using hormonal contraceptives or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm, a cervical cap, or a condom. Total abstinence from heterosexual intercourse, in accordance with the lifestyle of the subject, is also acceptable.

• Supine systolic blood pressure between 90 to 140 mmHg, inclusive, diastolic blood pressure between 45 to 90 mmHg, inclusive, and a heart rate between 40 to 100 bpm, inclusive, at screening. If initial results do not meet these criteria, blood pressure may be repeated if in the judgment of the Investigator there is a reason to believe the initial result is inaccurate.

• All prescribed medication must have been stopped at least 30 days prior to (first) admission to the clinical research center. An exception is made for hormonal contraceptives, which may be used throughout the study.

• All over-the-counter medication, vitamin preparations and other food supplements, or herbal medications (eg, St. John's wort) must have been stopped at least 14 days prior to (first) admission to the clinical research center. An exception is made for paracetamol, which is allowed up to admission to the clinical research center.

• Ability and willingness to abstain from alcohol from 48 hours (2 days) prior to screening and (first) admission to the clinical research center.

• Ability and willingness to abstain from methylxanthine-containing beverages or food (coffee, tea, cola, chocolate, energy drinks) and grapefruit (juice) from 48 hours (2 days) prior to (each) admission to the clinical research center.

• Good physical and mental health on the basis of medical history, physical examination, clinical laboratory, ECG, and vital signs, as judged by the Investigator.

• Willing and able to sign the ICF.

• Average intake of more than 24 units of alcohol per week: 1 unit of alcohol equals approximately 250 mL of beer, 100 mL of wine, or 35 mL of spirits).

• Participation in a drug study within 30 days prior to (the first) drug administration in the current study. Participation in 4 or more other drug studies in the 12 months prior to (the first) drug administration in the current study.

• Donation or loss of more than 450 mL of blood within 60 days prior to (the first) drug administration. Donation or loss of more than 1.5 liters of blood (for male subjects)/more than 1.0 liters of blood (for female subjects) in the 10 months prior to (the first) drug administration in the current study.

• Significant and/or acute illness within 5 days prior to (the first) drug administration that may impact safety assessments, in the opinion of the Investigator.

• Unwillingness to consume the FDA breakfast.

• Unsuitable veins for infusion or blood sampling.

• Vaccination against SARS-CoV-2 planned between 2 weeks prior to (first) admission and follow-up.
