Safety And Tolerability Of Multiple Doses Of PF-04950615 (RN316) In Subjects With Hypercholesterolemia

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Dose limiting and intolerable treatment-related AEs were the AEs resulting from drug overdose, drug withdrawal, drug abuse, drug misuse, drug interactions, drug dependency, extravasation, exposure in utero, exposure during breast feeding.

An AE was any untoward medical occurrence in 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-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 Day 78 that were absent before treatment or that worsened relative to pretreatment state.

An AE was any untoward medical occurrence in a participant who received study drug. AE was assessed according to common terminology criteria for adverse events (CTCAE) version 4.0 severity grades- Grade 1: mild (asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated); Grade 2: moderate (minimal, local or non invasive intervention indicated); Grade 3: severe (medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling); Grade 4: Life-threatening consequences; urgent intervention indicated and Grade 5: Death related to AE.

Criteria: Haemoglobin(Hgb), hematocrit, RBC: <0.8*lower limit of normal(LLN),mean corpuscular volume, mean corpuscular Hgb concentration <0.9*LLN or>1.1*upper limit of normal(ULN), platelet<0.5*LLN or>1.75*ULN, WBC<0.6*LLN or>1.5*ULN, lymphocyte, neutrophil<0.8*LLN or>1.2*ULN, basophil, eosinophil, monocyte>1.2*ULN; bilirubin>1.5*ULN, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, gamma glutamyl transferase, lactate dehydrogenase>3.0*ULN,total protein,albumin<0.8*LLN or>1.2*ULN; blood urea nitrogen, creatinine>1.3*ULN,uric acid>1.2*ULN;sodium<0.95*LLNor>1.05*ULN,potassium,chloride,calcium,bicarbonate<0.9*LLN or>1.1*ULN; glucose<0.6*LLN or >1.5*ULN, urine specific gravity<1.003 or>1.030,urine pH<4.5or>8,urine glucose, ketones, urine protein,urine blood/Hgb,urobilinogen,bilirubin,nitrite, leukocyte esterase>=1; urine RBC,WBC>=20,urine epithelial cells>=6,urine granular casts,hyaline casts>1,urine bacteria>20,partial thromboplastin time,prothrombin:>1.1*ULN.

Criteria for clinically relevant vital signs: supine and standing systolic blood pressure (SBP): less than (<) 90 millimeter of mercury (mmHg); supine and standing diastolic blood pressure (DBP): <50 mmHg. Maximum increase from baseline (IFB) or decrease from baseline (DFB) in supine and standing SBP: greater than or equal to (>=) 30 mmHg and maximum IFB or DFB in supine and standing DBP: >=20 mmHg. Supine pulse rate: <40 and greater than (>) 120 beats per minute (bpm); standing pulse rate: <40 and >140 bpm.

Criteria for clinically relevant ECG parameters: PR interval: maximum IFB of >=25 percent or 50 percent; QRS complex: maximum IFB of >=25 or 50 percent; QTcF interval (Fridericia's Correction): maximum IFB of >=30 millisecond (msec) to <60 msec and maximum IFB of >=60 msec.

The number of participants with at least one positive ADA were summarized for each treatment arm. Participants with positive antibody titer of >4.32 milligram/milliliter (mg/mL) were considered as ADA positive.

AUCtau is area under the concentration-time profile from time zero to time tau (τ), the dosing interval, where tau =168 hours.

Tmax is the time at which maximum plasma concentration (Cmax) occurred.

t1/2 was the time measured for the plasma concentration of PF-04950615 to decrease by one half. t1/2 was calculated as Loge(2)/kel, where kel was the terminal phase rate constant calculated by a linear regression of the log-linear concentration-time curve.

CL was calculated as Dose/AUCtau. AUCtau is area under the concentration-time profile from time zero to time tau, the dosing interval, where tau=168 hours.

Vss was calculated as CL*MRT. CL was calculated as Dose/AUCtau, where AUCtau was area under the concentration-time profile from time zero to time tau (τ), the dosing interval, where tau=168 hours. MRT was mean residence time (predicted) extrapolated to infinity.

Rac was calculated as Day 22 AUCtau divided by Day 1 AUCtau, where AUCtau is area under the concentration-time profile from time zero to time tau (τ), the dosing interval, where tau =168 hours.
