Physical examination included assessment of height, weight, blood pressure and pulse rate. Criteria for abnormal physical findings was based on investigator's discretion and were reported as adverse event (AE), as planned.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 22 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

Total number of participants with any laboratory abnormalities was reported.

Criteria for vital signs abnormalities: supine systolic blood pressure (SBP) <90 millimeter of mercury (mmHg), supine diastolic BP (DBP) <50 mmHg, supine pulse rate <40 beats per minute (bpm). Maximum increase or decrease from baseline in supine SBP >=30 mmHg and maximum increase or decrease from baseline in supine DBP >=20 mmHg.

Criteria for potential clinical concern in ECG parameters: maximum PR interval of greater than or equal to (>=) 300 milliseconds (msec), maximum QRS interval >=140 msec, maximum QTCF interval (Fridericia's Correction) of 450 to <480 msec, 480 to <500 msec and >=500 msec, maximum increase of >=25 percent (%) for baseline value of >200 msec for PR interval and maximum increase of >=50% for baseline value of less than or equal to (<=) 200 msec for QRS interval, maximum increase from baseline of >=30 msec to <60 msec and maximum increase from baseline of >60 msec in QTCF interval (Fridericia's Correction).

Capillary blood glucose levels were collected to observe any hypoglycemic adverse events. Hypoglycemia was assessed as following categories; Severe hypoglycemia (1. Participant was unable to treat himself/herself, requiring assistance of another person to actively administer carbohydrate, glucagon 2. Exhibited one of following neurological symptoms memory loss, uncontrollable behavior, irrational behavior, unusual difficulty in awakening, suspected seizure, seizure or loss of consciousness, 3. Glucose <50 mg/dL confirmed on repeat measure); Documented symptomatic hypoglycemia (1. Symptoms of hypoglycaemia accompanied by a measured glucose concentration <=70 mg/dL); asymptomatic hypoglycemia (not accompanied by typical symptoms of hypoglycaemia but with a measured glucose concentration <=70 mg/dL), and probable hypoglycemia (typical symptoms of hypoglycaemia are not accompanied by a glucose determination, but was presumably caused by a plasma glucose concentration <=70 mg/dL).

Criteria for blood glucose abnormality: Blood glucose levels <0.6*lower limit of normal (LLN) or >1.5*upper limit of normal (ULN).

Plasma terminal half-life is the time measured for the plasma concentration to decrease by one half at the terminal phase. Participants who received PF-05231023 with C-terminal and N-terminal t1/2 were reported.

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.Participants who received PF-05231023 with C-terminal and N-terminal CL were reported.

Volume of distribution 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. PF-05231023 with C-terminal and N-terminal Vz were reported.

AUC (0 - ∞)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞). PF-05231023 with C-terminal and N-terminal AUC (0 - ∞) were reported.

C0 was estimated by back-extrapolating from the first 2 concentration values using the log-linear regression on the first 2 data points (where second concentration was less than [<] first concentration) to back-extrapolate C0. PF-05231023 with C-terminal and N-terminal C0 were reported.

Vss was calculated by dividing the area under the first moment curve from time zero to infinity [AUMC(0-∞)] with the product of area under the curve from time zero to extrapolated infinite time [AUC (0 - ∞)] and apparent clearance (CL). PF-05231023 with C-terminal and N-terminal Vss were reported.
