Brief Summary:
Metformin may have complex interactions in the gut and is generally first line therapy for type 2 diabetes mellitus (T2DM). It is important to understand whether there are significant pharmacokinetic or pharmacodynamic interactions when GSK2330672 is co-administered with metformin in subjects with T2DM. The purpose of this study is to investigate the safety and tolerability of GSK2330672 administered for 7 days to subjects with T2DM taking metformin. This will be a two-period crossover study; subjects will receive either GSK2330672 or placebo for 7 days in each period separated by a washout period of 13 to 15 days. All subjects will receive metformin throughout the study

    12-lead ECG assessments were obtained pre-dose at Day 1, Day 3, Day 8 (before discharge) and Follow-up.

Bristol Stool Form Scale Rating: 1=separate hard lumps, like nuts, 2=sausage shaped but lumpy, 3=like a sausage or snake but with cracks on its surface, 4=like a sausage or snake, smooth and soft, 5=soft blobs with clear cut edges, 6=fluffy pieces with ragged edges, a mushy stool, 7=watery, no solid pieces. Data is reported for number of events in participants with each category of BSFR scale across Day 1 to 7 post morning dose.

  12. Mean Change From Baseline in Overall Gastrointestinal Symptom Rating Scale (GSRS) Scores [ Time Frame: Baseline (Day -1) and Day 8 of each treatment period ]
    The impact of gastrointestinal (GI) symptoms on health-related quality of life was assessed using the GSRS. The GSRS is a 15-item related to abdominal pain, reflux, indigestion, diarrhea and constipation syndromes, self-administered questionnaire that assesses the impact of gastrointestinal symptoms during the past week on a scale from 1 (no discomfort at all) to 7 (very severe discomfort). Overall GSRS is the mean of questions 1-15 and range from 1 to 7, with lower scores indicating a better quality of life with respect to gastrointestinal symptoms. Baseline was defined as the assessment done on Day -1. Change from baseline was calculated by subtracting the baseline (Day -1) values from the post-baseline value (Day 8).


Secondary Outcome Measures :
  1. Maximum and Weighted Mean Change From Baseline in Plasma Glucose Concentrations Over a 24 Hour (h) Period on Day 7 [ Time Frame: Baseline (Day -1) and Day 7 of each treatment period ]
    Baseline was defined as the time matched assessment done on Day -1. Change from baseline was calculated by subtracting the baseline (Day -1) time matched values from the post-baseline value (Day 8). Data is reported for fasting glucose level and for weighted mean and maximum values for fasting, 0-4 h, 4-10 h, 10-14 h and 0-24 h. Area under the curve (AUC) with respect to these time interval was calculated using the linear trapezoidal rule by the sum of the areas between each chronological pair of assessments (using observed times). The weighted mean was then determined by dividing the AUC by the observed length of the collection interval (time of last assessment - time of first assessment in h). Analysis was done using analysis of covariance (ANCOVA) model where, change from baseline was summation of baseline, period, sequence and treatment. Participants were fitted as a random effect.

  2. AUC From Time 0 to 10 h (AUC 0-10 h) of Metformin in Presence of GSK2330672 or Placebo on Day 7 [ Time Frame: Pre-dose (0 h), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7 of each treatment period ]
    AUC(0-10) for metformin when co-dosed with GSK2330672 or placebo is defined as the the area under the plasma concentration-time curve from time 0 to 10 h. It was determined using the linear trapezoidal rule for increasing concentrations and the logarithmic trapezoidal rule for decreasing concentrations. Blood samples were collected at 0 h (pre-dose within 15 min of dose and began eating breakfast immediately after taking study drug and finished eating in 15 min), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7. Analysis was done using a mixed effects model with fixed effect terms for treatment, period, and sequence. Participant within sequence was fitted as a random effect in the model.

  3. Maximum Plasma Concentration of Metformin (Cmax) in Presence of GSK2330672 or Placebo on Day 7 [ Time Frame: Pre-dose (0 h), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7 of each treatment period ]
    Cmax is defined as the first occurrence of the maximum observed plasma concentration determined directly from the raw concentration-time data Blood samples were collected at 0 h (pre-dose within 15 min of dose and began eating breakfast immediately after taking study drug and finished eating in 15 min), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7. Analysis was done using a mixed effects model with fixed effect terms for treatment, period, and sequence. Participant within sequence was fitted as a random effect in the model.

  4. Median Time to Observed Peak Plasma Concentration (Tmax) When Co-dosed With GSK2330672 or Placebo on Day 7 [ Time Frame: Pre-dose (0 h), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7 of each treatment period ]
    Tmax is defined as the time at which Cmax is observed, determined directly from the raw concentration-time data. Blood samples were collected at 0 h (pre-dose within 15 min of dose and began eating breakfast immediately after taking study drug and finished eating in 15 min), 0.25 h, 0.50 h, 1 h, 2 h, 3 h, 4 h (pre-lunch), 5 h, 5.5 h, 6 h, 8 h and 10 h (pre-dinner) on Day 7.

Subjects with a history of cholelithiasis and uncomplicated cholecystectomy more than 3 months before screening may be eligible if approved by the GlaxoSmithKline (GSK) Medical Monitor; No excessive alcohol intake.
  • C-peptide of >0.8 nanogram (ng)/mL at screening visit.

  • In good general health with (in the opinion of the investigator) no clinically significant and relevant abnormalities of medical history or physical examination that would introduce additional risk factors or interfere with study procedures or objectives, based on a medical evaluation including medical history, physical examination, vital signs and laboratory tests.
  • Female subjects of non-childbearing potential. Non-childbearing potential is defined as: Pre-menopausal females with a documented tubal ligation or hysterectomy [for this definition, "documented" refers to the outcome of the investigator's/designee's review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records]. Postmenopausal defined as 12 months of spontaneous amenorrhea. In questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli international units (MIU)/mL and estradiol < 40 picograms (pg)/mL (<147 picomole [pmol]/liter [L]) is confirmatory. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the acceptable 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 enrollment. For most forms of HRT, at least 2 to 4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.
