Results
A total of 527 patients were randomized before scheduled
surgery; of which, 130 (25%) experienced breakthrough
PONV and became eligible to receive the study medications
(Table 1, Fig. 1). The proportion of subjects completing the
study as planned per treatment arms ranged from 88% to
96% with an overall average of 93%, with no patient being
withdrawn due to AEs.
Complete response, defined as no emesis and no further
rescue medication from 10 min after infusion end up to 24 h
or discharge from the hospital orclinic, was achieved in the majority
of patients (56%) in the total population of patients
treated with vestipitant compared with 42% in the ondansetron
group (Table 2). The only vestipitant dose group which
had a lower complete response rate than the ondansetron
group was the vestipitant 18 mg group with a complete
