Study Endpoints
Primary Endpoints
Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64
Time to Reach Maximum Observed Plasma Concentration (Tmax) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64
Maximum Observed Plasma Concentration (Cmax) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64
Plasma Decay Half-Life (t1/2) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64

Plasma decay half-life is the time measured for the plasma concentration of PF-04950615 to decrease by one half.

Systemic Clearance (CL) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64

CL is a quantitative measure of the rate at which a drug substance is removed from the body.

Volume of Distribution at Steady State (Vss) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64

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 blood concentration of a drug.

Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUC0-inf) of PF-04950615
0 (pre-dose on Day 4), 1, 4, 8 and 12 hours (hrs) post intravenous PF-04950615 (RN316) dose, pre atorvastatin dose on Day 5, 6, 7, 15, 22, 29, 36, 43, 50, 57 and 64
Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4

AUCtau was the AUC from time 0 to the end of the dosing interval, where the dosing interval was 12 hours.

Time to Reach Maximum Observed Plasma Concentration (Tmax) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4, pre atorvastatin dose on Day 5, 6 and 7
Maximum Observed Plasma Concentration (Cmax) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4, pre atorvastatin dose on Day 5, 6 and 7
Plasma Decay Half-Life (t1/2) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4, pre atorvastatin dose on Day 5, 6 and 7

Plasma decay half-life is the time measured for the plasma concentration of atorvastatin to decrease by one half.

Apparent Oral Clearance (CL/F) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4

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.

Apparent Volume of Distribution (Vz/F) of Atorvastatin
0 (pre-dose), 0.25, 0.5, 1, 2, 3, 4, 6, 8 and 12 hrs post-dose on Day 4

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.
