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.

Eligibility criteria: Inclusion Criteria:

* Healthy male or female of non childbearing potential participants aged 18 to 65 (inclusive) years for Caucasian participants and 20 to 65 (inclusive) years for Japanese participants with suitable veins for cannulation or repeated venepuncture
* Japanese or Caucasian ethnicity
* Post-menopausal women must have had ≥ 12 months of spontaneous amenorrhea with an follicle stimulating hormone (FSH) concentration consistently ≥ 40 mIU/mL and a negative serum or urine pregnancy test result at Screening or Day -1. Surgically sterile women must have had a hysterectomy, and bilateral ovariectomy (oophorectomy), must provide documentation of the procedure and have had a negative serum or urine pregnancy test at Screening or Day -1. An intermediate or positive pregnancy test, can be confirmed by repeating the pregnancy test and demonstrating non-doubling of β-human chorionic gonadotropin levels every 48 to 72 hours
* Men who are biologically capable of fathering children must agree and commit to use of an adequate form of a highly effective method of contraception and refrain from sperm donation for the duration of the Treatment Period and for 3 months after the last administration of study treatment
* Body mass index 18 and 30 kg/m\^2, weight at least 50 kg
* No clinically significant abnormality identified on medical or laboratory evaluation at Screening unless the Investigator considers that the finding will not introduce additional risk factors and will not interfere with the study procedures
* 12-lead electrocardiogram recorded at Screening and Day -1 that is normal for the age group and shows no significant abnormalities that will compromise safety
* Physical examinations with no significant findings at Screening and on Day -1.

Exclusion Criteria:

* Participation in another clinical study or use of any experimental medication, device, or biologic with an investigational product (IP) within 5 half-lives of that IP or 3 months (whichever is longer) prior to first dosing
* Participation in another study investigating any form of anti-NGF or anti-TNF therapy in the 6 months prior to Screening and until after the final Follow-up Visit
* Any positive laboratory result at screening for COVID-19
* Blood donation or draw in excess of 400 mL within 2 months prior to Screening or plasma donation in excess of 50 mL within 30 prior to Screening
* Inability to comply with study-related restrictions and requirements related to consumption of alcohol, provision of meals and snacks, nicotine use, activity, blood donation, and contraception

* Clinically significant osteoarthritis (OA) currently affecting a major joint in the upper or lower extremity or axial spine; or other degenerative disease affecting any joint in participants for whom, there is an identified risk of osteonecrosis, rapidly progressing OA, subchondral insufficiency fractures, neurogenic arthropathy, or analgesia-induced arthropathy; or history of trauma or surgery involving any major joint or axial spine
* Radiological significant abnormalities reported on baseline MRI of hips and knees that are considered to present a risk of osteonecrosis, rapidly progressive OA, subchondral insufficiency fractures; or other coincidental finding(s) that present a risk to the safety or welfare of the participant
* History of excessive alcohol intake
* History of cancer within 5 years, with the exception of non-metastatic basal cell carcinoma of the skin, carcinoma in situ of the cervix or non-progressive prostate cancer
* History of drug abuse or positive test for drugs of abuse or alcohol

* Any clinically important or significant abnormality on a physical examination, vital signs, ECG or clinical laboratory test results that could be detrimental to participant safety or compromise the study
* Positive serologic findings at Screening for Human immunodeficiency virus antibodies, hepatitis B surface antigen or hepatitis C virus antibodies
* Positive QuantiFERON test for tuberculosis
* Any minor medical or surgical procedure or trauma within 28 days of Day 1 or planned surgical procedure during the study.
