study which will be conducted at four clinical units. Participants will be randomized to receive AZD5148, or placebo administered by intramuscular (IM) injection into the lateral thigh muscle or intravenous (IV) bolus (single, discrete dose of a drug).\n\nThis study will include 7 dose cohorts, two of which will include exclusively participants of Chinese descent, Cohort 2b and 4b. Each dose cohort will begin with a Sentinel Group of 2 participants randomized 1:1 (AZD5148:placebo). The participants in the Sentinel Group will undergo a safety monitoring period of 24 hours before the remaining participants in that cohort are dosed. If there would be no safety concerns, the remaining participants in the cohort will be dosed in a 9:1 ratio (AZD5148: placebo). Each participant will be involved in the study for up to 56 weeks (including Screening Period)\n\nThe study will comprise:\n\n* A Screening Period of maximum 28 days (Day -28 to Day -1 inclusive).\n* A Treatment and Follow-up Period lasting 12 months after the administration of the study drug.\n\n * Participants will be resident at the Clinical Unit from the day before study drug administration (Day -1) until all assessments are completed on Day 2.\n * A final Follow-up Visit will occur within 361 ± 14 days after the study drug administration.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Healthy participants with suitable veins for cannulation or repeated venipuncture at the time of consent.\n* All women must have a negative serum pregnancy test at the Screening Visit.\n* Women of childbearing potential must have a negative urine pregnancy test on admission to the Clinical Unit.\n* Women of childbearing potential must not be lactating and if heterosexually active must agree to use an approved method of highly effective contraception, to avoid pregnancy from 3 months prior to administration of the study drug and until 360 days after the dose of the study drug.\n* Women of non-childbearing potential must be confirmed at the Screening Visit by fulfilling one of the following criteria:\n\n 1.
