This is a Phase 1, randomized, 2 way crossover, open label study of the effect of PF-04965842 on metformin (a probe for MATE1/2K activity) PK in healthy adult participants. The effect of PF-04965842 on N1-methylnicotinamide (NMN; an endogenous biomarker for MATE1/2K) PK and its correlation to the effect on metformin PK will also be assessed. Participants will be randomized to 1 of 2 treatment sequences as described below. A total of 12 healthy male and/or female participants will be enrolled in the study so that 6 participants will be enrolled in each treatment sequence. Each treatment sequence will consist of 2 periods.

Primary | Renal Clearance (CLr) of Metformin | CLr was calculated as cumulative amount of drug recovered unchanged in urine during the dosing interval (Ae) divided by area under the plasma concentration time-curve from time zero to end of dosing interval (AUCtau). | For both Period 1 and Period 2 at intervals of 0-12, 12-24, 24-36, and 36-48 hours post metformin dose | |
Secondary | Area Under the Plasma Concentration-time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) of Metformin | AUCinf is a measure of the serum concentration of the drug over time. It was used to characterize drug absorption. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Maximum Plasma Concentration (Cmax) of Metformin | Cmax is maximum observed plasma concentration. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Time for Cmax (Tmax) of Metformin | Tmax of metformin administrated with or without PF-04965842. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Area Under the Plasma Concentration Time Profile From Time 0 to the Time of Last Quantifiable Concentration (AUClast) of Metformin | AUClast of metformin administrated with or without PF-04965842. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Apparent Clearance (CL/F) of Metformin | CL/F is a quantitative measure of the rate at which drug was removed from the blood. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Apparent Volume of Distribution (Vz/F) of Metformin | Vz/F is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Terminal Half-life (t1/2) of Metformin | t1/2 is the time measured for the plasma concentration to decrease by one half. | Pre-dose and at 0.5, 1, 2, 4, 6, 8, 12, 16, 24, 36 and 48 hours post-dose of metformin on Day 1 for both Period 1 and Period 2 | |
Secondary | Cumulative Amount of Drug Recovered Unchanged in Urine From 0 to 48 Hours (Ae) of Metformin | Ae is the cumulative amount of drug recovered unchanged in urine during the dosing interval. Cumulative amount was calculated as sum of urine drug concentration in sample volume for each collection interval. Sample volume = (urine weight in gram [g]/1.020), where 1.020 g/mL is the approximate specific gravity of urine. | For both Period 1 and Period 2 at intervals of 0-12, 12-24, 24-36, and 36-48 hours post metformin dose | |
Secondary | Percent of Dose Recovered Unchanged in Urine From 0 to 24 Hours (Ae%) of Metformin | Ae% is percent of dose recovered unchanged in urine from 0 to 24 hours post-dose of metformin. | For both Period 1 and Period 2 at intervals of 0-12 and 12-24 hours post metformin dose | |
Secondary | Number of Participants With Laboratory Abnormalities | Laboratory parameters included: hematology (hemoglobin, hematocrit, erythrocytes, ery. mean corpuscular volume, ery. mean corpuscular hemoglobin, ery. mean corpuscular HGB concentration, platelets, leukocytes, lymphocytes, neutrophils, basophils, eosinophils, monocytes, activated partial thromboplastin time, prothrombin time, prothrombin intl. normalized ratio, large unstained cells/leukocytes and large unstained cells), clinical chemistry (bilirubin, direct bilirubin, indirect bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, protein, albumin, blood urea nitrogen, urea, creatinine, urate, sodium, potassium, chloride, calcium, bicarbonate, urobilinogen and glucose -FASTING), urinalysis (specific gravity, pH, urine glucose, ketones, urine protein, urine hemoglobin, urine bilirubin, nitrite and leukocytes). Clinical significance of laboratory parameters is determined at the investigator's discretion. | Screening (within 28 days prior to Day 1) to Day 7 | |
Secondary | Number of Participants With Categorical Vital Signs Meeting Pre-defined Criteria | Criteria for change in vital signs: pulse rate value less than (<) 40 beats per minute (bpm) or value over than (>) 120 bpm, systolic blood pressure (SBP) value < 90 millimeter of mercury (mmHg) or change from baseline (Chg) equal to or over than (=) 30 mmHg increase or = Chg 30 mmHg decrease, diastolic blood pressure (DBP) value < 50 mmHg or Chg = 20 mmHg increase or Chg = 20 mmHg decrease. | Screening (within 28 days prior to Day 1) to Day 7 | |
Secondary | Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) (All Causalities and Treatment-related) | AEs with all causalities were any untoward medical occurrences in a study subject administered a product or medical device which did not necessarily had causal relationship with the treatment or usage. An SAE was an AE resulting in any of the following endpoints or deemed significant for any other reason: death; life threatening (immediate risk of death); inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect; or considered to be an important medical event. Treatment-related AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent are events between first dose of study drug and up to 35 days after last dose that were absent before treatment or that worsened relative to pretreatment state. | Day 1 up to Day 40 (35 days after the last dose of metformin) | |
