Study Overview
=================
Brief Summary
-----------------
This study will evaluate safety, tolerability, pharmacokinetics and immunogenicity of MEDI7352 in healthy participants.

Detailed Description
-----------------
The study will comprise: A Screening Period of up to 36 days (approximately 5 weeks); A Treatment Period of 6 weeks where participants will be given 1 dose of study treatment every 2 weeks (4 doses in total). Participants will be required to stay in the Clinical Unit from Days -1 to 8 (Visit 2), from Days 14 to 15 (Visit 6), from Days 28 to 29 (Visit 9), and from Days 42 to 50 (Visit 12). In addition, participants will have multiple visits to the Clinical Unit to complete the study assessments; A Follow-up Period of 42 days (6 weeks) where participants will also have multiple visits to the Clinical Unit to complete the study assessments, and; A final Follow-up Visit after 42 days after the Treatment Period. Participants will receive fixed multiple subcutaneous (SC) doses of MEDI7352 or placebo on 4 occasions; one dose every 2 weeks on Days 1, 15, 29 and 43, under fasted conditions.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Cohort 1: Japanese MEDI7352<br>Randomized Japanese participants will receive single doses of MEDI7352 subcutaneously. | Drug: MEDI7352<br>* A dose of MEDI7352 will be administered as two 1.5 mL injections in the abdomen. Following an overnight fast of at least 8 hours, each participant will receive a single dose of MEDI7352 on 4 occasions.<br>|
| Placebo Comparator: Cohort 1: Japanese Placebo<br>Randomized Japanese participants will receive matching placebo subcutaneously. | Drug: Placebo<br>* Matching placebo will be administered as two 1.5 mL injections in the abdomen.
