Relative Bioavailability, Safety, and Tolerability of Single-dose Sotrovimab Injection in Adults (COSMIC)

Stopped early · Phase 1

Conditions studied: Covid19

In brief

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). Part B and Part C (cohort 2) were optional so they were not initiated. Part C cohort 1 was discontinued early in the context of evolving variants with increased fold changes in the in vitro half maximal inhibitory concentration (IC50) and uncertainty in the clinical relevance of these changes.
