Study of Belimumab Administered Subcutaneously to Healthy Subjects

1 août 2013 mis à jour par: Human Genome Sciences Inc.

A Randomized, Parallel-Group, Open-Label Study to Evaluate the Absolute Bioavailability, Pharmacokinetics, Tolerability and Safety of a High Concentration Formulation of Belimumab (HGS1006), a Fully Human Monoclonal Anti-BLyS Antibody, Administered Subcutaneously to Healthy Subjects

The purpose of this study is to measure the amount of belimumab in the blood when given as an injection under the skin (subcutaneously; SC) and to evaluate the safety and tolerability of multiple injections under the skin in healthy subjects.

Bioavailability (F) is a measurement of the rate and extent to which a drug reaches the systemic circulation.
