Drug Overview
Selinexor (Karyopharm Therapeutics/Ono Pharmaceutical) selectively inhibits the transport protein exportin-1 (XPO1), also called chromosome region maintenance-1.
XPO1 is responsible for the transport of around 220 proteins from the nucleus of the cell to the cytoplasm, including many growth regulators and tumor suppressors. By preventing the export of these proteins, they are retained in the nucleus, leading to growth inhibition. XPO1 has been shown to be crucial for multiple myeloma (MM) cell survival, and selinexor inhibits MM cell growth and induces apoptosis in vivo and in vitro. It has also been shown to overcome proteasome inhibitor resistance in cells when added to Kyprolis (carfilzomib; Amgen/Ono Pharmaceutical) or Velcade (bortezomib; Takeda/Johnson & Johnson).
