This is a randomized, multicenter, open-label phase 2 study of the SINE compound, selinexor given orally versus restricted investigator choice (i.e., one of three potential salvage therapies).~Participants who have never been transplant eligible, are currently deemed unfit for intensive chemotherapy, ≥ 60 years old, who have AML (except Acute Promyelocytic Leukemia: APL, AML M3) after one prior treatment of either hypomethylating agent or a regimen including Ara-C, and are meeting the inclusion and exclusion criteria will be randomized to receive either oral selinexor or physician's choice (one of three potential treatments: best supportive care (BSC) alone, or BSC + hypomethylating agent, or BSC + low dose Ara-C until disease progression, death or intolerance has occurred.

Participants age ≥ 60 years with relapsed or refractory AML of any type except for AML M3, after one prior therapy only, who have never undergone and who are not currently eligible for stem cell transplantation and are currently deemed unfit for intensive chemotherapy.
