Details and patient eligibility

About

SAD study:

Eighteen subjects will be included in the SAD study (single dose) in 3 parallel arms, each with 6 subjects. The 3 arms will receive a single dose of one of the CS1 formulations I, II or III. The result of the pharmacokinetics analysis from the 6 first subjects is defined as SAD Pilot and will be used to evaluate the timing of PK sampling. Based on pharmacokinetic evaluations from all 18 subjects one of the formulations I (275 mg), II (276 mg) or III (276 mg) will be chosen to proceed into the MAD study. If none of the formulations show the desired PK properties the formulations may be re-dosed with a slightly different timing of the dose, i.e the IMP to be administered earlier or later during the evening.

MAD study:

Fifteen subjects will be included in a dose escalating study with 2 dose levels. The subjects will receive the lowest dose level (275 or 276 mg depending on the outcome of SAD) for the first 2 weeks before the dose is doubled (550 or 552 mg depending on the outcome of SAD) for the following 2 weeks.

Enrollment: 30 patients

Sex: All

Ages: 40 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Willing and able to give written informed consent for participation in the study
2. Male and female subjects age ≥ 40 years, ≤ 75 years inclusive.
3. BMI 27- 35 kg/m2
4. PAI-1 levels minimum 15 kIE/L (applies only to the MAD study)
5. 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.
6. 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 .
7. 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) -

Exclusion criteria:

1. History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.

2. Subjects with active or chronic liver disease or personal or familiar history of drug related severe hepatic dysfunction.

3. Subjects with phorphyria.

4. Subjects with Systemic lupus erytematosus (SLE)

5. Subjects with TPK, APTT, INR levels which are significant outside the reference intervals as judged by the investigator.

6. History of severe bleeding disease or thrombotic disease.

7. Subjects on regular treatment with anticoagulant or antiplatelets drugs

8. Subjects with significant cardiac disease.

9. Subjects with significant pancreatic disease.

11. Any clinically significant illness, medical/surgical procedure or trauma within four weeks of the first administration of IMP.

12. Any planned major surgery within the duration of the study.

13. Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibody and Human Immunodeficiency Virus (HIV).

14. 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

Administration of another new chemical entity (defined as a compound which has not been approved for marketing) or has participated in any other clinical study that included drug treatment with less than three months between administration of last dose and first dose of IMP in this study. Subjects consented and screened but not dosed in previous phase I studies are not excluded.
