The study will be a randomised, single-blind (sponsor-unblinded), placebo-controlled, study to investigate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of repeat intravenous infusions (2 doses 4-weeks apart) of GSK1070806 in obese patients with T2DM. The primary objective of the study will be to assess improvements in fasting and postprandial glucose control. This will be a parallel-group study in 30 obese subjects with T2DM who are poorly controlled on metformin monotherapy (HbA1C>7% but <9.5%), and who have levels of microalbuminuria indicative of progressive kidney disease i.e. 30-300mg/L albumin in urine or ACR ≥3.5 mg/mmol (female) or ≥2.5 mg/mmol (male) and ≤30mg/mmol. There will be three treatment groups comprising two active and one placebo arm with 10 subjects per dose group. The study contains a broad range of biomarker assessments, the purpose of which is to evaluate the mechanistic basis by which GSK1070806 exerts its therapeutic benefit in subjects with T2DM.~Subjects will be randomised into one of the three treatment groups where they will receive two intravenous infusions of GSK1070806 or placebo twenty-eight days apart. A MMT challenge will be conducted on Day 1, Day 29, Day 57 and Day 85 for evaluation of the primary endpoints.
GSK1070806 is a humanised IgG1/kappa antibody which is directed against the soluble cytokine interleukin-18 (IL-18). The aims of this placebo controlled study are to evaluate the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of GSK1070806 in obese subjects with Type 2 diabetes mellitus (T2DM), and to gain a better understanding of the mechanism by which GSK1070806 exerts its therapeutic effects.
