Lapatinib steady-state plasma trough concentrations (ng/mL) in gastric cancer subjects with and without prior partial gastrectomy
Parameter | Intact stomach | Resected stomach | Ratioa |
---|---|---|---|
Cmin (ng/mL) at Week 1 | 821 (633–1,064; n = 57) | 532 (279–1,017; n = 9) | 0.65 (0.36–1.16; P = 0.219) |
Cmin (ng/mL) at Week 6 | 1,027 (712–1,482; n = 40) | 175 (68–452; n = 6) | 0.17 (0.07–9.40; P = 0.001) |
Abbreviations: Cmin, minimum plasma concentration.
Ratio, comparing steady-state plasma trough concentrations (ng/mL) between patients with gastric cancer with and without prior partial gastrectomy; geometric means, 90% CI.
