Inclusion Criteria

• Healthy males and females, 18 to 65 years (both inclusive) at signing of informed consent.
• Body Mass Index (BMI) between 18.5 and 30 kg/m2 (both inclusive).
• Body mass not less than 50 kg.

• Females, if:
• Not of childbearing potential, e.g., has been surgically sterilized, undergone a hysterectomy, amenorrhea for ≥ 12 months and considered post-menopausal, Note: In postmenopausal women, the value of the serum pregnancy test may be slightly increased.

• Participation in another study with an experimental drug, where the last administration of the previous IMP was within 8 weeks (or within 10 elimination half-lives for chemical entities or 2 elimination half-lives for antibodies or insulin), whichever is the longer) before administration of IMP in this study, at the discretion of the investigator.
• Treatment within the previous 3 months before the first administration of IMP with any drug with a well-defined potential for adversely affecting a major organ or system.
• A major illness during the 3 months before commencement of the screening period.
