Study Description

Brief Summary

This study is being conducted to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of GSK2330672 compared to sitagliptin when administered with metformin for 14 days to subjects with type 2 diabetes mellitus (T2DM). Approximately 72 male and female subjects aged 30-64 years with T2DM and currently taking metformin will be recruited for this study. Eligible subjects will begin a run-in period of 13-15 days to stabilize on metformin 850 milligram (mg) twice a day (BID). Subjects will then be randomized to GSK2330672 10 mg, 20 mg, 30 mg, 90 mg, matching placebo or open-label sitagliptin 50 mg for 14 days BID. Subjects will return for a follow-up visit 7-10 days after discharge.

    The change from Baseline was calculated by subtracting the Baseline values from the individual post-Baseline values. Baseline was defined as pre-dose Day -1 value. It was assessed on Baseline, Day 7 and 14. Data for fasting and weighted mean (WM) AUC(0-24 hour) glucose is provided. Statistics for least square mean is provided and participants withdrawing early were excluded. Results were based on an analysis of covariance (ANCOVA) model: change from Baseline = Baseline + treatment.

  2. Number of Participants With Incidence and Nature of Adverse Events (AEs) and Serious Adverse Events (SAEs) [Up to 14 days (treatment period)]

    An AE was defined as any untoward medical occurrence (MO) in a participant temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. The SAE was any untoward MO that, at any dose, results in death, life threatening, persistent or significant disability/incapacity, results in or prolongs inpatient hospitalization, congenital abnormality or birth defect, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition and alanine aminotransferase (ALT) >= 3× upper limit of normal (ULN) and total bilirubin >=2 × ULN (>35% direct) or ALT >=3 × ULN and international normalized ratio >1.5.

The normal range (NR) and PCI definition for abnormal parameters are: ALT (NR: 0-44, 0-32, 2-33; PCI: >=2×upper limit of normal [ULN]); AST (NR: 0-40; PCI: >=2× ULN) and total bilirubin (NR: 0.00-20.52; PCI: >=1.5× ULN).

  5. Number of Participants With Abnormal Urinalysis Data [Baseline (pre-dose Day -1), Day 7 and 15]

    Urinalysis included urine occult blood: trace to 3+, glucose: negative to 3+, protein: negative to 2+ and ketones: trace to negative by dipstick and microscopic examination included cast, cellular cast, granular cast, hyaline cast (none seen to 1) and RBC: 0-2, 3-10, 11-30, >30, WBC: none seen, 0-5, 1, 2, 4, <5, 6-10, 11-30, 19, >30). The plus sign increases with a higher level of occult blood, glucose, ketones, proteins, RBC, WBC in the urine: 1+: slightly positive, 2+: positive, 3+: high positive. Participants were categorized as none seen or 1 based on the absence or presence, respectively, of cast, cellular cast, granular cast and hyaline cast. Higher value indicates higher abnormality.

  6. Summary of Urinalysis Data-mean Specific Gravity [Baseline (pre-dose Day -1), Day 7 and 15]

    Data for mean specific gravity is provided. Specific gravity is a measure of the amount of material dissolved in the urine. Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. Normal urine has a specific gravity between 1.010 and 1.020.

  7. Summary of Urinalysis Data-mean pH [Baseline (pre-dose Day -1), Day 7 and 15]

    Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0).

  8. Number of Participants With Abnormal Electrocardiogram (ECG) Findings Any Time Post-Baseline [Up to Day 15]

  14. Number of Participants With Gastrointestinal Tolerability Assessments as Rated Using the Gastrointestinal Symptom Rating Scale (GSRS; With Worsening Symptoms >=2 Levels) [Day 7 and 14]

    GSRS is a rating scale consisting of 15 items. Each item was scored from 1: no discomfort at all, 2: minor discomfort, 3: mild discomfort, 4: moderate discomfort, 5: moderately severe discomfort, 6: severe discomfort, 7: very severe discomfort. The overall GSRS score is the mean of these 15 items, varying from 1 to 7; a score of 1 indicates that no symptoms are present, and a score of 7 indicates the worst possible degree of all symptoms. A higher score relative to Baseline indicates worsening of severity. There were 5 defined syndrome scores and 1 overall score that was derived by computing the mean of the scores for specific subsets of questions as indicated below: abdominal pain (1, 4, 5); reflux syndrome (2, 3); diarrhea syndrome (11, 12, 14); indigestion syndrome (6, 7, 8, 9); constipation syndrome (10, 13, 15) and overall GSRS (1-15).

Participant Flow

Recruitment Details The study was conducted from 27 August 2014 to 30 January 2015. After interim analysis of safety, tolerability, pharmacodynamic and/or pharmacokinetic (PK) data, GSK2330672 10 and 20 milligram (mg) doses were dropped and GSK2330672 60 mg was added.
Pre-assignment Detail A total of 187 participants were screened, of these, 112 were screen failures and 75 entered the run-in period. Five participants were withdrawn prior to taking a metformin dose in the 14 days of run-in period. A total of 64 participants were randomized to receive investigational product, as 6 participants were withdrawn prior to randomization.

Outcome Measures

1. Primary Outcome
Title Change From Baseline in Derived Plasma Glucose Parameter Over a 24-hour Period-fasting and Weighted Mean Glucose Area Under Curve (AUC[0-24 Hour])
Description The change from Baseline was calculated by subtracting the Baseline values from the individual post-Baseline values. Baseline was defined as pre-dose Day -1 value. It was assessed on Baseline, Day 7 and 14. Data for fasting and weighted mean (WM) AUC(0-24 hour) glucose is provided. Statistics for least square mean is provided and participants withdrawing early were excluded. Results were based on an analysis of covariance (ANCOVA) model: change from Baseline = Baseline + treatment.
Time Frame Baseline (Day -1) and Day 14 (Fasting Pre-dose [within 15 minutes of dose], 30 minutes, 1, 1.5, 2, 4 [pre-lunch], 5.5, 10 [pre-dinner], 11.5, 14 [bed time] and 24 hours) and Day 7 (30 minutes, 2, 4 [pre-lunch], 5.5, 10 [pre-dinner], 11.5, and 24 hours)

2. Primary Outcome
Title Number of Participants With Incidence and Nature of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Description An AE was defined as any untoward medical occurrence (MO) in a participant temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP and can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with its use. The SAE was any untoward MO that, at any dose, results in death, life threatening, persistent or significant disability/incapacity, results in or prolongs inpatient hospitalization, congenital abnormality or birth defect, that may not be immediately life-threatening or result in death or hospitalization but may jeopardize the participant or may require medical or surgical intervention to prevent one of the other outcomes listed in this definition and alanine aminotransferase (ALT) >= 3× upper limit of normal (ULN) and total bilirubin >=2 × ULN (>35% direct) or ALT >=3 × ULN and international normalized ratio >1.5.

5. Primary Outcome
Title Number of Participants With Abnormal Urinalysis Data
Description Urinalysis included urine occult blood: trace to 3+, glucose: negative to 3+, protein: negative to 2+ and ketones: trace to negative by dipstick and microscopic examination included cast, cellular cast, granular cast, hyaline cast (none seen to 1) and RBC: 0-2, 3-10, 11-30, >30, WBC: none seen, 0-5, 1, 2, 4, <5, 6-10, 11-30, 19, >30). The plus sign increases with a higher level of occult blood, glucose, ketones, proteins, RBC, WBC in the urine: 1+: slightly positive, 2+: positive, 3+: high positive. Participants were categorized as none seen or 1 based on the absence or presence, respectively, of cast, cellular cast, granular cast and hyaline cast. Higher value indicates higher abnormality.

6. Primary Outcome
Title Summary of Urinalysis Data-mean Specific Gravity
Description Data for mean specific gravity is provided. Specific gravity is a measure of the amount of material dissolved in the urine. Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. Normal urine has a specific gravity between 1.010 and 1.020.

Title Summary of Urinalysis Data-mean pH
Description Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0).

Title Number of Participants With Gastrointestinal Tolerability Assessments as Rated Using the Gastrointestinal Symptom Rating Scale (GSRS; With Worsening Symptoms >=2 Levels)
Description GSRS is a rating scale consisting of 15 items. Each item was scored from 1: no discomfort at all, 2: minor discomfort, 3: mild discomfort, 4: moderate discomfort, 5: moderately severe discomfort, 6: severe discomfort, 7: very severe discomfort. The overall GSRS score is the mean of these 15 items, varying from 1 to 7; a score of 1 indicates that no symptoms are present, and a score of 7 indicates the worst possible degree of all symptoms. A higher score relative to Baseline indicates worsening of severity. There were 5 defined syndrome scores and 1 overall score that was derived by computing the mean of the scores for specific subsets of questions as indicated below: abdominal pain (1, 4, 5); reflux syndrome (2, 3); diarrhea syndrome (11, 12, 14); indigestion syndrome (6, 7, 8, 9); constipation syndrome (10, 13, 15) and overall GSRS (1-15). The data is presented for participants with worsening of symptoms in >=2 levels.
