Trial overview
Official title: A phase 1, randomised, double-blind, placebo-controlled study of the safety, tolerability, pharmacokinetics and pharmacodynamics of single subcutaneous doses of GSK2330811 in healthy Japanese participants
Trial description: This is a randomized, double-blind (sponsor-open), placebo-controlled, single-center study involving Japanese participants. The purpose of the study is to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and immunogenicity after a single subcutaneous (SC) dose of GSK2330811 in healthy Japanese participants. GSK2330811 is a humanized immunoglobulin G1 (IgG1) monoclonal antibody that binds and inhibits the action of Oncostatin M (OSM) and is being developed for the treatment of Crohn’s disease (CD) and Systemic sclerosis (SSc). Participants will be randomized to receive either GSK2330811 (450 milligram [mg]) or placebo in an approximate ratio of 7:3.

Accepts healthy volunteers
Yes
- Participant must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
- Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests and 12-lead ECGs.
- Participants with sensitivity to any of the study treatments or components there of (including humanized monoclonal antibodies) or history of severe post treatment hypersensitivity reactions including erythema multiforme major, linear immunoglobulin A (IgA) dermatosis, toxic epidermal necrolysis and exfoliative dermatitis.
- Participants with any other history of significant allergy that in the opinion of the investigator contraindicates their participation in this study.
Inclusion and exclusion criteria
Inclusion criteria:
- Participant must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
- Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests and 12-lead ECGs.
- A participant with a clinical abnormality or laboratory parameters outside the reference range for the healthy population being studied that is not specifically listed in the inclusion or exclusion criteria may be included if the investigator and sponsor medical monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures or interpretation.
- Participants with body weight >=45 kilogram (kg) and body mass index (BMI) within the range 18.5-29.9 kg per square meter.
- Male participants.
- Participants capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol.
- Participants with Japanese ancestry, defined as having been born in Japan, being descendants of four ethnic Japanese grandparents and two ethnic Japanese parents, holding a Japanese passport or identity papers, and being able to speak Japanese. Participants should have lived outside Japan for less than 10 years at the time of screening.
Exclusion criteria:
- Participants with sensitivity to any of the study treatments or components there of (including humanized monoclonal antibodies) or history of severe post treatment hypersensitivity reactions including erythema multiforme major, linear immunoglobulin A (IgA) dermatosis, toxic epidermal necrolysis and exfoliative dermatitis.

- Participants with alanine aminotransaminase (ALT) >1.5 times upper limit of normal (ULN) at any time during screening.
- Participants with bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin <35 percent) at any time during screening.
- Participants with presence of hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb), or positive hepatitis C virus (HCV) antibody result at screening. Participants with positive HCV antibody due to prior resolved disease can be enrolled only if a confirmatory negative HCV Ribonucleic acid (RNA) test is obtained.
- Participants with positive human immunodeficiency virus (HIV) antibody test at screening.
- Participants with positive pre-study drug or alcohol screen.
- Participants with history of regular alcohol consumption within 6 months of the screening visit in excess of an average weekly intake of >21 units. One unit is equivalent to 8 gram of alcohol: a half-pint (approximately 240 mL) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
