Change from baseline = observed value minus baseline value.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) or Serious Adverse Events (SAEs)Baseline up to Day 169

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 169 that were absent before treatment or that worsened relative to pretreatment state. Adverse events included treatment emergent injection site adverse events and any clinically significant abnormal laboratory value.

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - ∞)] of PF-04950615Multiple dose (Day 99: pre-dose, 24, 72, 120, 168, 336, 504, 672, 1008 hr post-dose)

Area under the plasma concentration-time profile from time zero extrapolated to infinite time. This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.

Plasma Concentration of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9)Day 1, 5, 8, 15, 22, 29, 36, 43, 50, 57, 71, 85, 99, 106, 113, 127, 141

Concentration versus time summary was calculated by setting concentration values below the lower limit of quantification (LLQ =6.99 nanogram per milliliter \[ng/mL\]) to zero. Summary statistics were not to be presented if number of observations above lower limit of quantification (NALQ) =0. Here, 'Number analyzed' = Participants evaluable for this outcome measure at specified time points.

Percent Change From Baseline in Total Cholesterol (TC) / High Density Lipoprotein- Cholesterol (HDL-C) Ratio at Day 85 and Day 113Baseline, Day 85, 113

Fasting was required at least 10 hours before blood sample collection. Baseline was defined as the mean of the last two non-missing measurements collected prior to the first dose of study treatment. Both measurements must be within 10 days prior to the first dose of study treatment; if only one measurement was available 10 days prior to the first dose of study treatment, then that measurement served as the baseline value. Percent change from baseline = (\[observed value divided by baseline value\] minus 1) multiplied by 100.

Terminal Elimination Half-Life (t1/2) of PF-04950615Multiple dose (Day 99: pre-dose, 24, 72, 120, 168, 336, 504, 672, 1008 hr post-dose)

Terminal elimination half-life is the time measured for the plasma concentration to decrease by one half. This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.
