The Phase 3 XPORT-EC-042 trial of selinexor maintenance in TP53 wild-type endometrial cancer did not meet its primary PFS endpoint. A numerical trend favoring selinexor was seen in the mITT population (HR 0.76, p=0.0791) but did not reach statistical significance. The company will present full data at a future medical meeting and states that results do not affect other ongoing selinexor trials.
