Brief Summary

GSK2330811 is a humanised monoclonal antibody, that blocks Oncostatin M (OSM), which is being developed for the treatment of inflammatory and fibrotic diseases. This first time in human study will evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD) and immunogenicity profile of single ascending subcutaneous (s.c.) doses of GSK2330811, in healthy subjects. This study will be a randomised, double-blind (sponsor open), placebo-controlled, single centre, single dose escalation study of s.c. administrations of GSK2330811 in healthy subjects. Approximately 40 subjects will be enrolled in the study, across 5 cohorts. Each cohort is planned to consist of 8 subjects, randomised such that 6 subjects will receive GSK2330811 and 2 subjects will receive placebo. The starting dose for the study will be 0.1 milligram (mg)/kilogram (kg) s.c. single dose and the highest dose will be 6 mg/kg s.c. single dose. Subjects will be admitted to the clinical unit on the day prior to dosing (Day -1). On Day 1, each subject will receive a s.c. dose of GSK2330811 or placebo. Subjects will then remain as an in-patient until discharged on Day 8, after assessments have been performed. The duration of the study, including screening, is approximately 19 weeks for Cohorts 1 to 4 and 23 weeks for Cohort 5.

Outcome Measures

Primary Outcomes (4)

• Safety and tolerability as assessed by number of subjects with adverse event (AEs) and serious adverse events (SAEs)

  From Day 1 up to Day 105 (For Cohort 5 up to Day 133)

• Safety and tolerability as assessed by composite of clinical laboratory tests: clinical chemistry, hematology and urinalysis

  Clinical laboratory tests will include clinical chemistry, hematology and urinalysis.

These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
• Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the consent form and in this protocol.
• Subjects with any values for alanine aminotransferase (ALT), aspartate aminotransferase (AST), or creatinine that are above the upper limit of normal (ULN); any values for platelets or haemoglobin that are below the lower limit of normal (LLN); or any out of normal range values for white blood cells (WBC), reticulocytes, serum sodium, or serum potassium.
• Any history of gastreointestinal bleeding disorders such as peptic ulcer disease, haematemesis or other gastrointestinal bleeding.
• Subjects with medical conditions associated with increased risk of complications from bleeding.
• A history of haematological disease, such as anaemia, or acquired platelet disorders and coagulation disorders, including drug-induced thrombocytopaenia, idiopathic thrombocytopaenia or von Willebrand's disease.
• Donation of blood in excess of 500 mL within a 56 day period prior to dosing.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
