A Study to Assess the Effects of Fluvoxamine on Savolitinib Exposure in Healthy Male Subjects

This study will be a Phase I, open-label, fixed-sequence, 2-treatment period study.

The study will consist of 2 periods. During period 1 of the study, each subject will receive a single oral dose of savolitinib following an overnight fast. A low-fat breakfast will be provided prior to dosing. There will be a minimum washout period of 10 days (14 days between two successive savolitinib doses) between period 1 and period 2.

During period 2 of the study, subject will take oral doses of fluvoxamine alone from Days 1 to 4. There would be no dietary restrictions for fluvoxamine dosing. On Day 5, subjects will take a single oral dose of savolitinib and oral dose of fluvoxamine. On Day 6, subject will receive an oral dose of fluvoxamine alone. Each subject would be involved in the study for 9 weeks (including screening window).
