Study Investigation Pharmacokinetics and Pharmacodynamics of CS1

Inclusion criteria

• Willing and able to give written informed consent for participation in the study
• Male and female subjects age ≥ 40 years, ≤ 75 years inclusive.
• BMI 27- 35 kg/m2
• PAI-1 levels minimum 15 kIE/L (applies only to the MAD study)
• Acceptable medical history, physical findings, vital signs, ECG and laboratory values at the time of screening, as judged by the Investigator. Subjects with stable hypertension with one or more antihypertensive drugs can be accepted as acceptable medical history.
• Male subjects who has not documented a vasectomy, must be willing to use condom from the date of dosing until three months after dosing of the IMP to prevent drug exposure of a partner and refrain from donating sperm and if they have a fertile partner, she must use contraceptive methods with a failure rate of < 1% to prevent pregnancy .
• The females must be of non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or post-menopausal defined as 12 months of amenorrhea (simultaneous determination of follicle stimulating hormone 25-140 IU/l and estradiol < 200 pmol/l is confirmatory) -

• Any planned major surgery within the duration of the study.
• Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody and Human Immunodeficiency Virus (HIV).
• After 10 minute supine rest at the time of screening, any vital signs values outside the following ranges:

• Systolic blood pressure > 160 mm Hg
• Diastolic blood pressure > 100 mm Hg

Subjects consented and screened but not dosed in previous phase I studies are not excluded.
