This is a randomized, double-blind, sequential, dose-escalation, Phase 1 trial to evaluate the safety and tolerability of verdinexor. Verdinexor or placebo will be given on Days 1 and 3 to healthy adult participants.~Cohorts of 8 participants each (6 active, 2 placebo) will be sequentially administered verdinexor or placebo (one dose on Day 1 and one dose on Day 3) using a dose-escalation scheme. A conservative, sequential, dose-escalation strategy employing decreasing escalation increments will be used.
