A new medicine for multiple myeloma has been approved by the US Food and Drug Administration giving patients whose disease is resistant to several other drugs, an option for treatment. The small molecule drug, Xpovio (selinexor), can now be used by patients who have received at least four other therapies, but without success. Resistance in these patients has been shown to proteasome inhibitors, immunomodulatory agents and an anti-CD38 monoclonal antibody.
