A Multiple Dose Study of PF-04950615 (RN316) in Subjects on High Doses of Statins

Lipid parameters included: high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), non-high-density lipoprotein-cholesterol (non-HDL-C), triglyceride (TG), apolipoprotein B (ApoB) and apolipoprotein A1 (ApoA1). Baseline value was calculated as the average of Day 7 and Day 1 measurements collected prior to study drug administration.

Baseline value was calculated as the average of Day 7 and Day 1 measurements collected prior to study drug administration.

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. Serious adverse event (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. TEAEs are events between first dose of study drug and up to Day 141 that were absent before treatment or that worsened relative to pretreatment state. Treatment related: a TEAE deemed related to the study drug by the investigator. TEAEs included SAEs (TESAEs) as well as non-serious AEs which occurred during the study. The participants with TEAEs, SAEs and treatment-related TEAEs were reported.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. Investigator assessed TEAEs as mild (did not interfere with participant's usual function), moderate (interfered to some extent with participant's usual function) or severe (interfered significantly with participant's usual function). TEAEs are events between first dose of study drug and up to Day 141 that were absent before treatment or that worsened relative to pretreatment state.

Criteria for clinical significant vital signs: maximum increase or decrease from baseline in supine systolic blood pressure (BP) greater than or equal to (>=) 30 millimeter of mercury (mmHg), maximum increase or decrease from baseline in supine diastolic BP of >=20 mmHg. Criteria for clinically significant ECG parameters: maximum increase of >=25 percent (%) for baseline value of >200 millisecond (msec) and maximum increase of >=50% for baseline value of less than or equal to (<=) 200 msec for PR and QRS interval; maximum increase from baseline of >30 to <=60 msec and maximum increase from baseline of >60 msec for QT interval corrected using the Fridericia's formula (QTCF).

Human serum ADA samples of participants who received PF-04950615 (RN316) were analyzed for the presence of anti-PF-04950615 (RN316) antibodies by using the semi quantitative enzyme-linked immunosorbent assay (ELISA). Results with titer value >=4.32 nanogram per milliliter of anti-PF-04950615 antibodies were counted as positive. Number of participants with presence of anti-PF-04950615 antibodies were reported in this outcome measure.
