Investigational Product (IP): INS018_055 Presentation: Liquid in a glass vial: 2 ml at 50 microgram/ml Mode of Administration: Intravenous Participants will be admitted to the CRU on Day 1 where they will be domiciled until Day 2 (i.e. 24 hours after administration of INS018_055). On Day1, participants will be administered a single dose of INS018_055 via IV injection and will be monitored for safety. Blood for PK analysis will be collected before and after (i.e. 5, 15, and 30 minutes, and 1, 2, 4, and 8 hours) the administration of INS018_055. On Day 2 (i.e. after 24 hours after INS018_055 administration), a final blood sample for PK analysis will be collected and participants will undergo safety assessments before being discharged from CRU.
