Purpose
This study is to evaluate the safety, tolerability and immunogenicity of single, ascending or multiple fixed subcutaneous and intravenous administrations of PF 05335810 to hypercholesterolemic subjects when added on to a daily statin dose.

Primary Outcome Measures:
- Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Baseline up to Day 85/169 or Early Termination (ET) ]Counts of participants who had treatment-emergent adverse events (TEAEs), defined as newly occurring or worsening after first dose. Relatedness to [study drug] was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.
- Number of Participants With Laboratory Test Values of Potential Clinical Importance [ Time Frame: Baseline up to Day 85/169 or Early Termination (ET) ]Pre-defined criteria were established for each laboratory test to define the values that would be identified as of potential clinical importance.
- Change From Baseline in Heart Rate [ Time Frame: Baseline, Day 1 to 85/169 or ET ]
- Diastolic Blood Pressure [ Time Frame: Baseline, Day 1 to 85/169 or ET ]
- Change From Baseline in Electrocardiogram (ECG) Parameters [ Time Frame: Baseline, Day 1 to 85/169 or ET ]
- Number of Participants With Laboratory Test Values of Potential Clinical Importance [ Time Frame: Baseline, Day 1 to 85/169 or ET ]Pre-defined criteria were established for each laboratory test to define the values that would be identified as of potential clinical importance.
Secondary Outcome Measures:
- Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0 - 8)] [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]AUC (0 - 8)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - 8). It is obtained from AUC (0 - t) plus AUC (t - 8).
- Area Under the Curve From Time Zero to Last Quantifiable Concentration [AUC (0-t)] [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]AUC (0-t)= Area under the plasma concentration versus time curve from time zero (pre-dose) to time of last quantifiable concentration (0-t)
- Maximum Observed Plasma Concentration (Cmax) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]
- Time to Reach Maximum Observed Plasma Concentration (Tmax) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]
- Apparent Volume of Distribution (Vz/F) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]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. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.
- Apparent Oral Clearance (CL/F) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.
- Plasma Decay Half-Life (t1/2) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.
- Absolute Bioavailability (%F) [ Time Frame: Day1 pre-dose to Day 85/169 or ET ]
