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.

Eligibility Criteria

Inclusion Criteria

• Between 18 and 65 years of age inclusive, at the time of signing the informed consent.
• Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, vital signs and a 12-lead ECG.

Exclusion Criteria

• Cohorts 1-4: Body weight <=100 kg and body mass index (BMI) within the range 18.5 - 29.9 kilogram per meter square (kg/m^2) (inclusive); Cohort 5: Body weight <=80 kg and BMI within the range 18.5 - 29.9 kg/m^2 (inclusive).
• Female subjects are eligible to participate if not pregnant (as confirmed by a negative serum [screening] and urine [Day -1] human chorionic gonadotrophin [hCG] test), not lactating, and at least one of the following conditions applies:
• Pre-menopausal females with one of the following: Documented tubal ligation, Documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, Hysterectomy, Documented Bilateral Oophorectomy.
• Postmenopausal defined as 12 months of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone [FSH] and estradiol levels consistent with menopause). Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of post-menopausal status prior to study enrolment.
• Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until 15 weeks after dosing of study medication:
• Vasectomy with documentation of azoospermia.
• Male condom plus partner use of one of the contraceptive options as follows: Contraceptive subdermal implant that meets the Standard Operating Procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label; Oral Contraceptive, either combined or progestogen alone injectable progestogen; Contraceptive vaginal ring; percutaneous contraceptive patches. 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.

• History of regular alcohol consumption within 6 months of the study defined as an average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 grams of alcohol: a half-pint (~240 mL) of beer, 1 glass (125 mL) of wine or 1 (25 mL) measure of spirits.
• Smokers who would not be able to refrain from smoking whilst in the phase I unit.
• History of sensitivity to any components of the study medication, or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation.

• Exposure to more than four new chemical or four new biological entities within 12 months prior to the first dosing day.
• Subject is unable to abstain from travelling to regions of high endemic infection, as determined by the investigator, for the duration of the study.
