Human serum anti-drug antibody (ADA) samples were analyzed for the presence or absence of anti-tanezumab antibodies by using the semi-quantitative enzyme-linked immunosorbent assay (ELISA).

Area Under the Curve From Time Zero to Extrapolated Infinite Time [AUC (0-infinity)] - Part 1Part 1: Pre-dose, Day 1 (10 minutes, 0.5, 1, 4, 12 hours post intravenous infusion), Day 2, 3, 4/5, 8, 15, 22, 29, 43, 57, 71, 92, 120 post-infusion

AUC (0-infinity) is defined as the area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-infinity). It is obtained from AUC (0-t) plus AUC (t-infinity).

Systemic Clearance (CL) - Part 1Part 1: Pre-dose, Day 1 (10 minutes, 0.5, 1, 4, 12 hours post intravenous infusion), Day 2, 3, 4/5, 8, 15, 22, 29, 43, 57, 71, 92, 120 post-infusion

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

Plasma Decay Half-Life (t1/2) - Part 1Part 1: Pre-dose, Day 1 (10 minutes, 0.5, 1, 4, 12 hours post intravenous infusion), Day 2, 3, 4/5, 8, 15, 22, 29, 43, 57, 71, 92, 120 post-infusion

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