GSK256073

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, may jeopardize the participant or require medical or surgical intervention to prevent one of the other outcomes listed in the definition above, or is an event of possible drug-induced liver injury.

Mean of triplicate measurements at each time point was considered for the summary. Baseline was defined as pre-dose of Day 1 visit. Change from Baseline was calculated by subtracting the Baseline values from the corresponding post-treatment values. It was assessed on Baseline, Day 1 (12 hours), Day 2 (pre-dose and 12 hours), Week 3, 6 (pre-dose and 12 hours), 9 and 12.

Mean of triplicate measurements at each time point was considered for the summary. Baseline was defined as pre-dose of Day 1 visit. Change from Baseline was calculated by subtracting the Baseline values from the corresponding post-treatment values. It was assessed on Baseline (pre-dose Day 1), Day 1 (12 hours), Day 2, Week 3, 6, 9 and 12.

Single 12-lead ECGs were obtained at each time point during the study using an ECG machine that automatically calculated the heart rate and measured PR, QRS, QT, and QTc intervals. It was assessed at Baseline (pre-dose Day 1), Day 2, Week 3, Week 6 and 12. Participants with normal, abnormal not clinically significant and abnormal clinically significant ECG were presented.

Clinical chemistry parameters included blood urea nitrogen (BUN), potassium, aspartate aminotransferase (AST), total bilirubin, direct bilirubin, creatinine, chloride, alanine aminotransferase (ALT), uric acid, fasting glucose, total carbon dioxide, gamma glutamyltransferase (GGT), albumin, sodium, calcium, alkaline phosphatase (ALP), total protein, creatine phosphokinase (CPK) and fasting lipid panel including total cholesterol, triglycerides, high density lipoprotein (HDL) cholesterol and low density lipoprotein (LDL) cholesterol. It was assessed on Baseline (pre-dose Day 1), Week 3 and 12. Data for parameters with high and low of PCI is provided.

Hematology parameters included platelet, red blood cell (RBC) count, mean corpuscular volume (MCV), neutrophils, white blood cell (WBC) count (absolute), mean corpuscular hemoglobin (MCH), lymphocytes, reticulocyte count, mean corpuscular hemoglobin concentration (MCHC), monocytes, hemoglobin, eosinophils, hematocrit and basophils. It was assessed on Baseline (pre-dose Day 1) and 12. Data for parameters with high and low of PCI is provided.

Urinalysis parameters included glucose, protein, blood and ketones by dipstick. It was assessed on Baseline (Day -1) and 12. Urine glucose was measured as grams per deciliter (G/dL).

Blood samples for analysis of HbA1c were collected at Baseline (Day -1), Day 41, Week 9 and Week 12. Change from Baseline was calculated by subtracting the Baseline values from the corresponding post-treatment values. Baseline was defined as Day -1 visit. Statistics is provided for least square mean at Week 12.

The potential PK/PD relationship was to be assessed by plotting GSK256073 AUCs against HDLc. The PK/PD model that was to be used for the simulations in the study design was to be refined with the Part A observed AUC exposures and HDLc levels. However, the study was stopped for futility at the end of Part A due to lack of a compelling PK/PD relationship between GSK256073 and lipid effects that would predict success in achieving significant HDLc raising.
