Safety, Tolerability, Pharmacokinetics, Pharmacodynamics of GSK2330811 in Healthy Japanese Participants
April 28, 2021 updated by: GlaxoSmithKline
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
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.

Measure Description |
Time Frame |
---|---|---|
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Up to Day 126
|
An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention.
A SAE is defined as any untoward medical occurrence that, at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, congenital anomaly/birth defect, any other situation according to medical or scientific judgment.
Safety Population consisted of all randomized participants who received at least one dose of study treatment.
|
Up to Day 126
|
Number of Participants With Worst Case Vital Sign Results Relative to Potential Clinical Importance (PCI) Criteria Post-Baseline Relative to Baseline
Time Frame: Baseline (Pre-dose, Day 1) and up to Day 126
|
Vital signs were measured in semi-supine position after 5 minutes of rest and included systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR).
Participants were counted in the worst case category that their value changed to low, within range or high, unless there was no change in their category.
Participants whose value category was unchanged (e.g., High to High), or whose value became within range, were recorded in the "Within Range or No Change" category.
Participants were counted twice if values changed 'To Low' and 'To High', so the percentages were not added up to 100 percent (%).
Participants with missing Baseline values were assumed as within range value.
PCI ranges were: SBP (lower: <85, upper: >160 millimeter of mercury [mmHg]); DBP (lower: <45, upper: >100 mmHg); HR (lower: <40, upper: >110 beats per minute).
Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
|
Baseline (Pre-dose, Day 1) and up to Day 126
|
Change From Baseline in Body Temperature

|
Body temperature was measured in semi-supine position after 5 minutes of rest for the participants in a quiet setting without distractions.
Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.
|
Baseline (Pre-dose, Day 1), Day 1: 1, 4, 8 hours; Days 2, 3, 5, 7, 10, 14, 21, 28, 42, 56, 84 and 126
|
Number of Participants With Worst Case Abnormal Electrocardiogram (ECG) Findings
Time Frame: Up to Day 126
|
12-lead ECGs were recorded in semi-supine position using an ECG machine.
Number of participants with worst-case clinically significant and not clinically significant abnormal ECG findings have been presented.
Clinically significant abnormal laboratory findings were those which were not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
|
Up to Day 126
|
Number of Participants With Maximum Common Terminology Criteria for Adverse Events (CTCAE) Grade 1 or Higher Clinical Chemistry Parameters
Time Frame: Up to Day 126
|
Blood samples were collected for the analysis of clinical chemistry parameters.
Clinical chemistry parameters were summarized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0: Grade 1: mild; Grade 2: moderate; Grade 3: severe; Grade 4: life-threatening or disabling.
Higher grade indicates more severity.
Clinical chemistry parameters included: total bilirubin, calcium, creatinine and triglycerides.
|
Up to Day 126
|
Number of Participants With Grade Increase Post-Baseline Relative to Baseline in Hematology Parameters
Time Frame: Baseline (Pre-dose, Day 1) and up to Day 126
|
Blood samples were collected for the analysis of the following hematology parameters: hemoglobin (Hb), lymphocytes (Lympho), platelet count (PC), neutrophil count (Neutro) and White Blood Cell count (WBC).
The laboratory parameters were graded according to NCI-CTCAE version 5.0.
Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences.
Higher grade indicates more severity.
Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
An increase was defined as an increase in CTCAE Grade relative to Baseline Grade.
|
Baseline (Pre-dose, Day 1) and up to Day 126
|
Number of Participants With Worst Case Any Increase in Urinalysis Results Post-Baseline Relative to Baseline
Time Frame: Baseline (Pre-dose, Day 1) and up to Day 126
|
Urine samples were collected for analysis of blood, glucose, ketones and protein by a dipstick method.
The dipstick test gives results in a semi-quantitative manner, and results for urinalysis parameters of urine glucose, protein, blood and ketones can be read as negative (-), trace, 1+, 2+, 3+ indicating proportional concentrations in the urine sample.
Baseline was defined as the pre-dose Day 1 assessment, unless unavailable, in which case it was the latest pre-dose assessment.
Any increase means any increase to trace, 1+, 2+ or 3+ post-Baseline relative to Baseline.
Number of participants with worst case any increase in urinalysis results post-Baseline relative to Baseline has been presented.
