About

This study is divided into two parts:

Part A of the study is double blinded, randomized, placebo-controlled and aims to assess the safety, tolerability, pharmacokinetics (PK) and Pharmacodynamic (PD) effect of a single intravenous (IV) infusion dose of GSK1070806 when administered to healthy participants of Japanese, Chinese and European/Caucasian ancestry.

Part B of the study is an open label single cohort arm to assess the safety, tolerability, PK and PD effect of a single IV bolus low dose of GSK1070806 in healthy participants of European/Caucasian ancestry.

Enrollment: 38 patients
