Dose Ranging Study Of Bococizumab (PF-04950615; RN316) In Hypercholesterolemic Japanese Subjects

The purpose of this study is to evaluate the low density lipoprotein cholesterol (LDL-C) lowering effect of Bococizumab (PF-04950615;RN316) administered subcutaneously at every two weeks (Q14D) in hypercholesterolemic Japanese subjects whose LDL-C is not controlled by a stable dose of atorvastatin, or who are naïve to a treatment by lipid lowering drug and whose LDL-C is not controlled.

Primary outcomes

  1. Percent Change From Baseline in Fasting Low Density Lipoprotein-Cholesterol (LDL-C) at Day 85

    Time frame: Baseline, Day 85

    LDL-C is cholesterol in the bloodstream that is carried by low density lipoprotein. Fasting was required at least 10 hours before blood sample collection.

Percent change from baseline = ([observed value divided by baseline value] minus 1) multiplied by 100.

    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.

  41. Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of PF-04950615

    Time frame: Multiple 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 to the time of the last quantifiable concentration. This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.

  42. Maximum Observed Plasma Concentration (Cmax) of PF-04950615

    Time frame: Single dose (Day 1: pre-dose, 24, 48, 72, 96, 120, 144, 168 hr post-dose), Multiple dose (Day 99: pre-dose, 24, 72, 120, 168, 336, 504, 672, 1008 hr post-dose)

    This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.

  43. Minimum Observed Plasma Trough Concentration (Cmin) of PF-04950615

    Time frame: Multiple dose (Day 99: pre-dose, 24, 72, 120, 168, 336, 504, 672, 1008 hr post-dose)

    This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.

  44. Time to Reach Maximum Observed Plasma Concentration (Tmax) of PF-04950615

    Time frame: Single dose (Day 1: pre-dose, 24, 48, 72, 96, 120, 144, 168 hour (hr) post-dose), Multiple dose (Day 99: pre-dose, 24, 72, 120, 168, 336, 504, 672, 1008 hr post-dose)

    This outcome measure was to be analyzed in participants who received at least 1 dose of the PF-04950615.

  45. Terminal Elimination Half-Life (t1/2) of PF-04950615

    Time frame: Multiple 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.

  46. Plasma Concentration of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9)

    Time frame: 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.
