The main purpose of the study is to determine whether the test product and the reference product are bioequivalent based on the pharmacokinetics after administration of ug/kg as a single intravenous dose and as a single subcutaneous dose of each of the formulations. The study is consisted of randomization, 2 parts, 4 treatments, 2 way cross over.

6. Females of child-bearing potential, with a fertile male sexual partner, should be willing to use adequate contraception from screening 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 or cervical cap, or a condom.

Other exceptions are multivitamins and vitamin C, which are allowed up to 7 days before admission to the clinical research center.
9. All regular non-topical medication must have been stopped at least 30 days prior to (the first) admission the clinical research center. An exception is made for hormonal contraceptives, which may be used throughout the study.

11. Medical history without major pathology as judged by the PI
12. Normal resting supine blood pressure and pulse showing no clinically relevant deviations as judged by the PI.
13. Computerized (12-lead) electrocardiogram (ECG) recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the PI.
14. All values for clinical laboratory tests of blood and urine within the normal range or showing no clinically relevant deviations as judged by the PI. Hb, Hct, RBC count and thrombocytes should not exceed the upper limit of normal. Minor deviations can be accepted at the discretion of the PI
15. Willing and able to sign the ICF
