About Karyopharm
Karyopharm Therapeutics Inc. (Nasdaq:KPTI) is a clinical-stage pharmaceutical company focused on the discovery and development of novel first-in-class drugs directed against nuclear transport targets for the treatment of cancer and other major diseases. Karyopharm’s Selective Inhibitors of Nuclear Export (SINE) compounds function by binding with and inhibiting the nuclear export protein XPO1 (or CRM1). The inhibition of XPO1 by Karyopharm’s lead drug candidate, Selinexor (KPT-330), a first-in-class, oral SINE compound, leads to the accumulation of tumor suppressor proteins in the cell nucleus, which subsequently reinitiates and amplifies their tumor suppressor function. This is believed to lead to the selective induction of apoptosis in cancer cells, while largely sparing normal cells. SINE compounds have shown biological activity in models of cancer, autoimmune disease, certain viruses, and wound-healing.  Karyopharm was founded by Dr. Sharon Shacham and is located in Natick, Massachusetts.
