Primary Outcome Measures
NameTimeMethod
Metformin Pharmacokinetic (PK) Parameter Area Under the Plasma Concentration Versus Time Curve From Time 0 Extrapolated to Infinity (AUC[0-inf])Periods 1, 2, 3, & 4: pre-dosing, 15, 30, 45 mins & 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36 & 48 hrs post-dosing

PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. AUC (0-inf) is the area under the plasma concentration-time curve from time zero extrapolated to infinite time.

Metformin PK Parameter Observed Maximum Plasma Concentration (Cmax)Periods 1, 2, 3, & 4: pre-dosing, 15, 30, 45 mins & 1, 1.5, 2, 3, 4, 6, 8, 12, 18, 24, 36 & 48 hrs post-dosing

PK is the process by which a drug is absorbed, distributed, metabolized, and eliminated by the body. Cmax is the maximum observed concentration of drug substance in plasma.

Secondary Outcome Measures
NameTimeMethod
Participants With Abnormal Vital Sign Findings Reported as an AEFrom Day 1/Period 1 to study discharge or premature discontinuation. Duration of study was approximately 45 days (including screening).

per investigator

Participants With Adverse Events (AEs), Discontinuations Due to AEs, Deaths, and Serious AEs (SAEs)AEs: from study drug administration Day 1/Period 1 till study discharge. SAEs: from date of written consent until 30 days after discontinuation of dosing or study participation. Duration of the study was approximately 45 days (including screening).

AE=any new untoward medical occurrence or worsening of a pre-existing medical condition in a subject administered an investigational product and that does not necessarily have a causal relationship with this treatment. SAE=any untoward medical occurrence that results in death, is life-threatening, requires or prolongs inpatient hospitalization (including elective surgery), results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event.

Participants With Electrocardiogram Abnormalities Considered Clinically Significant or Reported as an AEFrom study drug administration Day 1/Period 1 till study discharge. Duration of the study was approximately 45 days (including screening).

Clinically significant was determined by the investigator. ECGs were recorded after participants had been supine for at least 5 minutes.

Participants With Abnormal Physical FindingsFrom Day 1/Period 1 to study discharge or premature discontinuation. Duration of study was approximately 45 days (including screening).

Physical findings that were considered abnormal by the investigator.

Participants With Clinical Laboratory Findings Considered Clinically Significant or Reported as an AE: HematologyFrom study drug administration Day 1/Period 1 till study discharge. Duration of the study was approximately 45 days (including screening).

Clinically significant was determined by the investigator.

Participants With Clinical Laboratory Findings Considered Clinically Significant or Reported as an AE: Serum ChemistryFrom study drug administration Day 1/Period 1 till study discharge. Duration of the study was approximately 45 days (including screening).

Clinically significant was determined by the investigator.

Participants With Clinical Laboratory Findings Considered Clinically Significant or Reported as an AE: UrinalysisFrom study drug administration Day 1/Period 1 till study discharge. Duration of the study was approximately 45 days (including screening).

Clinically significant was determined by the investigator.
