Trial overview

Official title: An open label positron emission tomography (PET) imaging study using 89Zirconium labeled GSK3128349 to investigate the biodistribution and clearance of an albumin binding domain antibody (AlbudAb) GSK3128349 following single dose intravenous administration in healthy male subjects
Trial description: GSK3128349 is a small protein molecule (biopharmaceutical) that binds to albumin in the body, and by itself, has no pharmacological action. A pharmacologically active drug can be attached to GSK3128349 with the goal of changing the distribution and/or duration of action of the attached drug. This study will determine the distribution and pharmacokinetics (duration) of GSK3128349 itself after a single intravenous infusion. GSK3128349 has been labeled with and the radioisotope 89Zirconium allowing it to be visualized in the organs of the body using a PET scanner at multiple time points after GSK3128349 dosing. The data from this study will help predict the distribution of future drugs attached to GSK3128349. The total duration of a subject’s participation is about approximately 10 weeks, including the screening period.
