Trial Outcomes & Findings for CP-690,550 Thorough QTc Study (NCT NCT01743677)

NCT ID: NCT01743677

Last Updated: 2020-09-16

Results Overview

Triplicate 12-lead electrocardiogram (ECG) measurements (each recording separated by approximately 2 minutes) were performed and average was calculated. The time corresponding to the beginning of depolarization to repolarization of the ventricles (QT interval) was adjusted for RR interval using the QT and RR from each ECG by Fridericia's formula (QTcF = QT divided by cube root of RR). Data is reported as Least Squares (LS) mean difference (CP-690,550 minus Placebo, baseline-adjusted).

AUC (0 - ∞)= Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0 - ∞). It is obtained from AUC (0 - t) plus AUC (t - ∞). Variation in CYP2C19 gene affected the pharmacokinetics of CP-690,550. AUC (0 - ∞) categorized by genotype into poor metabolizer, extensive metabolizer and ultra extensive metabolizer of CYP2C19.
