Overview
Brief Summary
This clinical pharmacology study will evaluate the relative bioavailability, safety, and tolerability of two different concentrations of sotrovimab injections administered at different injection sites in male or female healthy participants aged 18 to 65 years. The study will be conducted in three parts (Part A, an optional Part B and Part C).

Outcomes
Primary Outcomes
Part A (Treatment Arms 1 and 2): Area Under the Serum Concentration-time Curve (AUC) From Day 1 to Day 29 (AUC[D1 to 29]) Following Administration of Sotrovimab
Time Frame: Day 1: Pre-dose, 1, 2, 6 and 8 hours post-dose; Days 2, 3, 5, 8, 15 and 29 post-dose
Blood samples were collected at indicated time points for pharmacokinetic analysis of sotrovimab. Pharmacokinetic (PK) parameters were calculated using standard non-compartmental analysis.
Part A (Treatment Arms 1 and 2): Maximum Observed Concentration (Cmax) Following Administration of Sotrovimab
Time Frame: Day 1: Pre-dose, 1, 2, 6 and 8 hours post-dose; Days 2, 3, 5, 8, 15 and 29 post-dose
Blood samples were collected at indicated time points for pharmacokinetic analysis of sotrovimab. PK parameters were calculated using standard non-compartmental analysis.
Part A (Treatment Arms 1 and 2): Number of Participants With Serious Adverse Events (SAEs), Adverse Events of Special Interest (AESI) and Common (>=5%) Non-serious Adverse Events (Non-SAEs) Through Day 29
Time Frame: Up to Day 29
An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose: results in death, is life- threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, significant medical events that may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed before. Adverse events which were not Serious were considered as non-serious adverse events. Number of participants who had common (\>=5%) non-SAEs and SAEs are presented. AESIs included hypersensitivity reactions and injection site reactions based on a predefined list of terms.
Part C (Cohorts 1 and 2): Number of Participants With SAEs, AESIs and Common (>=5%) Non-SAEs Through Day 29
Time Frame: Up to Day 29
