and 1.13 ± 0.51 ng/mL, respectively) and oral contraceptive plus prucalopride (0.92 ± 0.51 ng/mL and 1.11 ± 0.48 ng/mL, respectively) [Fig. 3]. On day 5, Cmax was reached at a median time of 1 hour after dosing. There were no statistically significant differences in tmax, Cmin, Cmax, AUCτ, or t½ between treatments (Table 2). The geometric mean treatment ratios for Cmax and AUCτ were 98.07 % and 91.36 %, Interleukin-3 receptor respectively, and the associated 90 % CIs were within the predefined equivalence limits of 80–125 % for Cmax and AUCτ (Table 2). For Cmin, the geometric mean treatment ratio and the lower limit of the 90 % CI were below 80 % when all participants were included in the analysis. However, these parameters fell within the predefined equivalence limits when the data from the suspected non-compliant participant were omitted (Table 2). 3.4 Prucalopride Pharmacokinetics On day 1, the mean near-peak (3-hour) concentration of prucalopride was 4.56 ± 0.87 ng/mL. On day

5, prucalopride steady state was reached, with similar plasma concentrations pre-dose on days 5 and 6 and at 24 hours post-dose on day 6 (3.00 ± 1.16 ng/mL, 3.20 ± 0.84 ng/mL, and 3.13 ± 0.58 ng/mL, respectively). On day 5, the mean near-peak (3-hour) steady-state plasma concentration of prucalopride was 8.18 ± 1.64 ng/mL. 3.5 Prucalopride Safety and Tolerability No unexpected safety findings for prucalopride were identified on administration with ethinylestradiol and norethisterone. No deaths or serious or severe treatment-emergent AEs were reported. Treatment-emergent AEs were more common in participants receiving prucalopride plus oral contraceptive (39 events, n = 15 [93.8 %]) than in those receiving oral contraceptive alone (4 events, n = 4 [30.8 %]).
