Outcomes

Primary Outcomes

Area Under the Plasma Concentration-Time Curve From Time Zero to Time of Last Quantifiable Concentration (AUClast) of Metformin

Area under the plasma concentration vs time curve from time zero to the last sampling time t at which the concentration was at or above the lower limit of quantification (LLQ). AUC0-t was to be calculated according to the mixed log-linear trapezoidal rule.

Time frame: Part 1 (fasted): Pre-dose and 0.5, 1, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 24 and 32 hours post dose. Part 2 (fed): Pre-dose 1, 2, 3, 4, 5, 5.5, 6, 6.5, 7, 8, 9, 10, 12, 24 and 32 hours post dose

Maximum Observed Plasma Concentration (Cmax) of Metformin

Cmax was obtained directly from the concentration versus time curve.

Secondary Outcomes

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious TEAEs

An Adverse event (AE) was defined as any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease associated with the use of study drug, whether or not considered related to the study drug or worsening of pre-existing medical condition, whether or not related to study drug. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. An AE was considered as 'treatment emergent' if it occurred after the first drug administration of each period or if it was present prior to drug administration but exacerbated after the drug administration. TEAEs included both Serious TEAEs and non-serious TEAEs.

Time frame: From Day 1 up to 3 weeks

Number of Participants Taking Concomitant Medications

Concomitant medications included medications administered from the first administration of study interventions to the end of observation.

Time frame: From Day 1 up to 3 weeks

Number of Participants With Clinically Significant Change From Baseline in Laboratory Values

The laboratory measurements included hematology, blood chemistry, urinalysis and Blood Sugar Test (BST). Number of participants with clinically significant changes from baseline in laboratory values were reported. Clinically Significance was decided by investigator.

Time frame: From Day1 (baseline) up to 3 weeks

Number of Participants With Clinically Significant Change From Baseline in 12-lead Electrocardiogram (ECG) Findings

The 12-lead ECG recordings were obtained after 5 minutes of rest in a semi-supine position. ECG recordings included rhythm, ventricular rate, PR interval, QRS duration, QT and QTc intervals. Number of participants with clinically significant changes from baseline in 12-lead ECG findings were reported. Clinically significance was decided by investigator.

Time frame: From Day 1 (baseline) up to 3 weeks

Number of Participants With Clinically Significant Change From Baseline in Vital Signs

Vital sign assessment included blood pressure, pulse rate, body temperature and respiration rate. Number of participants with clinically significant changes from baseline in vital signs were reported. Clinically significance was decided by investigator.

Time frame: From Day 1 (baseline) up to 3 weeks

Number of Participants With Clinically Significant Change From Baseline in Physical Examination Findings

Physical examination included assessments of the skin, lungs, cardiovascular system, abdomen (liver and spleen), and the symptoms reported by the participant. Number of participants with clinically significant changes from baseline in vital signs were reported. Clinically significance was decided by investigator.

Time frame: From Day 1 (baseline) up to 3 weeks

Area Under Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Metformin

AUC0-inf was calculated by combining AUC0-t and AUC extra. AUC extra represents an extrapolated value obtained by Clast/ lambda z, where Clast is the calculated plasma concentration at the last sampling time point at which the measured plasma concentration is at or above the Lower Limit of quantification (LLQ) and lambda z is the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase.

Ratio of Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Sampling Time (AUC0-tlast) to Area Under the Plasma Concentration-Time Curve From Time Zero Extrapolated to Infinity (AUC0-inf) of Metformin

The ratio of AUClast to AUCinf were reported.

Apparent Terminal Half-Life (t1/2) of Metformin

Terminal half-life is the time measured for the concentration to decrease by one half. Terminal half-life calculated by natural log 2 divided by lambda z.

Time to Reach Maximum Observed Plasma Concentration (Tmax) of Metformin

Time to reach the maximum plasma concentration (Tmax) was obtained directly from the concentration versus time curve.
