Description

Inclusion Criteria

1. Provision of signed and dated, written informed consent prior to any study specific procedures.
2. Capable of giving signed informed consent as described in Appendix A which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
3. Aged 18 to 45 years (inclusive, at the time of signing the ICF).
4. Healthy, non smoking Chinese participants. Definition of non-smoker: non-smoker for at least the past 12 months with pack history ≤5 pack years.
5. Able and willing to comply with the requirements of the protocol and complete the study until the end of the safety follow up period.
6. Have a body mass index between 19 and 24 kg/m2 , inclusive.
7. Male and female.

8. Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception from enrolment throughout the study until their final follow-up visit. Cessation of contraception after this point should be discussed with a responsible physician. Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhoea method are not acceptable methods of contraception. Female condom and male condom should not be used together. All women of child bearing potential must have a negative serum pregnancy test result at Visit 1.

   • A highly effective method of contraception is defined as one that results in a low failure rate (i.e., less than 1% per year) when used consistently and correctly. Highly effective birth control methods include: a vasectomised partner, Implanon®, bilateral tubal occlusion, intrauterine device/levonorgestrel intrauterine system, Depo-Provera™ injections, oral contraceptive, and Evra Patch™, Xulane™, or NuvaRing®.

   Females not of childbearing potential who are either permanently sterilized (hysterectomy, bilateral oophorectomy, or bilateral salpingectomy), or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment prior to the planned date of randomization and follicle stimulating hormone (FSH) levels in the postmenopausal range.

9. Nonsterilised males who are sexually active with a female partner of childbearing potential must use condom and spermicide from enrolment through the study period until their final follow up visit. Because male condom and spermicide is not a highly effective contraception method, female partners of a male study participants must also use a highly effective method of contraception as defined above throughout this period.

Exclusion Criteria

14. Received administration of an investigational drug or participated in a device trial within 3 months and 5.5 half-lives, prior to screening (Visit 1).
15. History or current diagnosis of cancer, with the exception of cancer treated with apparent success with curative therapy (response duration of > 5 years).
16. History of an underlying condition that predisposes the participant to infections (e.g., history of splenectomy, known primary or secondary immune deficiency syndromes).
17. History of Inflammatory Bowel Disease or microscopic colitis.
18. A known history of severe reaction to any medication including biologic agents and human gamma globulin therapy.
