What is being measured
The primary outcome is the main question the study is designed to answer.
Area Under the Plasma Concentration-Time Curve From Time Zero to the Last Sampling Time (AUC 0-t) of Metformin (GIR Tablet Active Ingredient)
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.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Maximum Observed Plasma Concentration (Cmax) of Metformin (GIR Tablet Active Ingredient)
Pharmacokinetic (PK) parameter Cmax was obtained directly from the concentration versus time curve.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Secondary outcomes (10)
Time to Reach Maximum Plasma Concentration of Metformin (GIR Tablet Active Ingredient)
Time to reach the maximum plasma concentration (Tmax) was obtained directly from the concentration versus time curve.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Apparent Terminal Half-Life (t1/2) of Metformin (GIR Tablet Active Ingredient)
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 λz.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Area Under the Plasma Concentration-Time Curve From Time 0 to Infinity (AUCinf) of Metformin (GIR Tablet Active Ingredient)
AUC0-inf was calculated by combining AUC0-t and AUCextra. AUC extra represents an extrapolated value obtained by Clast/ λz, 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 λz is the apparent terminal rate constant determined by log-linear regression analysis of the measured plasma concentrations of the terminal log-linear phase.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Area Under the Plasma Concentration-Time Curve From Time Tlast Extrapolated to Infinity (AUCextra) of Metformin (GIR Tablet Active Ingredient)
AUCextra% was defined as area under the curve from time tlast extrapolated to infinity as percentage of AUC 0-infinity. Here, tlast is the last sampling time at which the concentration is at or above the lower limit of quantification.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Elimination Rate Constant (λz) of Metformin (GIR Tablet Active Ingredient)
λz was determined from the terminal slope of the log-transformed plasma concentration curve using linear regression method.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Total Body Clearance (CL/f) of Metformin (GIR Tablet Active Ingredient)
Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Apparent Volume of Distribution at After Extravascular Administration (Vz/f) of Metformin (GIR Tablet Active Ingredient)
Vz/f is defined as the distribution of a study drug between plasma and the rest of the body after oral dosing.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
Apparent Volume of Distribution at Steady-State After Extravascular Administration (Vss/f) of Metformin
Vss/F was derived from concentration versus time data for all participants.
Measured: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10, 14 hours post-dose on Day 1; 24 and 36 hours post-dose on Day 2; 48 hours post-dose on Day 3
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.
Measured: Baseline up to Day 15
Number of Participants With Clinically Significant Abnormalities in Vital Signs, Laboratory Parameters, Physical Examination Findings and 12-lead Electrocardiogram (ECG) Findings
The laboratory measurements included hematology, blood chemistry and urinalysis. Vital sign assessment included blood pressure, pulse rate and body temperature. ECG parameters included heart rate, PR, QRS,QT, RR, QTcB and QTcF Here, we are reporting number of participants with clinically significant abnormalities in Vital signs, laboratory parameters, physical findings and ECG findings.
Measured: Baseline up to Day 15
