Inclusion Criteria:

• The written informed consent must be signed before any study specific tests or procedures are done
• Age: 21 to 65 years (inclusive) at the first screening examination visit
• Body mass index (BMI) 18.5 to 32.0 kg/m2 (both inclusive) and a total body weight of 55 to 100 kg (both inclusive)
• Healthy male subject, as determined by a responsible and experienced physician, based on a medical evaluation including medical history, laboratory tests, physical, cardiac and full ophthalmologic examination
• Subjects of reproductive potential with a partner of child-bearing potential must agree to use adequate contraception when sexually active. This applies from signing of the ICF until 3 months after the study drug administration. The definition of adequate contraception will be based on the judgment of the investigator and on local requirements. Acceptable methods of contraception include, but are not limited to, (i) condoms (male or female, should not be used together) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device; (iv) hormone-based contraception. Subjects must agree to utilize two reliable and acceptable methods of contraception simultaneously. This is not required if safe contraception is achieved by a permanent method, such as vasectomy of the subject or bilateral fallopian tube blockage of the subject's partner; OR if the subject has no requirement for contraception (e.g. same sex partners).
