Indications and Usage
Selinexor is used along with dexamethasone to treat multiple myeloma (a type of cancer of the bone marrow) that has returned or that did not respond to at least 4 other treatments. Selinexor is also used with bortezomib and dexamethasone to treat multiple myeloma in patients who have previously been treated with at least one other medication. It is also used to treat certain types of diffuse large B-cell lymphoma (DLBCL; a type of cancer that begins in the white blood cells) in adults whose cancer has returned or is unresponsive to at least two other treatments. Selinexor is in a class of medications called selective inhibitors of nuclear export (SINE). It works by killing cancer cells.

For use in combination with dexamethasone for the treatment of multiple myeloma or for the treatment of DLBCL, selinexor is usually taken on days 1 and 3 of each week. For use in combination with bortezomib and dexamethasone for the treatment of multiple myeloma, selinexor is usually taken once a week.
