Abstract
e19532 Background: Netupitant (NETU) is a highly selective neurokinin 1 receptor antagonist (NK1 RA) developed to provide protection from nausea and vomiting in patients undergoing emetogenic chemotherapy. Three individual studies were aimed at determining NETU effect on the metabolism of the new generation 5-HT3 RA palonosetron (PALO), dexamethasone (DEX) and oral contraceptives which may be coadministered in clinical practice. Methods: Two 3-way crossover studies to determine the interaction between NETU (450 mg, day 1) and PALO (0.75 mg PO, day 1), and between NETU (100 mg, 300 mg or 450 mg PO, day 1) and DEX (20 mg PO, day 1; 8 mg BID PO, days 2-4), were performed in 18 and 25 healthy subjects, respectively. The study investigating the effect of NETU/PALO (300 mg/0.5 mg PO) as a fixed dose combination on the PK of oral contraceptives ethinylestradiol and levonorgestrel (60 μg/300 μg) was a 2-way crossover trial of 24 healthy women. Serial blood samples were collected over the course of the three studi...
