About this study

This is a prospective, multicenter, double-blind, placebo-controlled, randomized Phase 3 study.

Participants with primary stage IV or recurrent disease who are in partial or complete response after having completed a single line of at least 12 weeks of taxane-platinum combo therapy will be randomized in a 2:1 manner to maintenance therapy with 80 milligram (mg) with selinexor once weekly (QW) or placebo until progression.
