Description: For this double-blind, multi-center, randomized phase 2/3 trial (ClinicalTrials.gov Identifier: NCT02606461), researchers are evaluating the safety and efficacy of selinexor, an orally administered inhibitor of CRM1, among patients with unresectable dedifferentiated liposarcoma.

In the phase 2 portion of this trial, an estimated 100 patients will be randomly assigned 1:1 to selinexor or placebo; in the phase 3 portion, an estimated 195 patients will be randomly assigned 2:1 to selinexor or placebo.

The primary endpoint is progression-free survival. Total estimated enrollment is 245 patients.
