Ratios of Risankizumab Cmax and AUC in Healthy Japanese and Chinese Subjects Relative to White Subjects
Regimens | Exposure Ratiosa (Not Accounting for Body Weight) | Exposure Ratiosa (Adjusted for Body Weight) | |||
---|---|---|---|---|---|
Test vs Reference | Pharmacokinetic Parameter | Point Estimate | 90%CI | Point Estimate | 90%CI |
Japanese vs white | Cmax | 1.32 | 1.03–1.69 | 0.84 | 0.61–1.14 |
AUC∞ | 1.31 | 1.10–1.56 | 1.02 | 0.81–1.30 | |
Chinese vs white | Cmax | 1.35 | 1.06–1.70 | 1.08 | 0.86–1.35 |
AUC∞ | 1.22 | 1.03–1.45 | 1.05 | 0.88–1.25 |
AUC∞ indicates area under the plasma concentration‐time curve from time 0 to infinity; Cmax, maximum plasma concentration.
Ratio was calculated by exponentiation of the difference between the logarithms of the least‐squares means calculated based on 1‐way ANOVA.
