NATICK, Mass., March 26, 2013 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc., a leader in the new field of nuclear transport modulators, announces fifteen (15) poster presentations covering its Selective Inhibitors of Nuclear Export (SINE), oral small molecule XPO1/CRM1 antagonists, at the AACR meeting on April 6 – 13, 2013, in Washington DC. Karyopharm's lead oral XPO1 inhibitor KPT-330 is currently in Phase 1 testing in adult patients with advanced hematologic and solid tumors (NCT01607892, NCT01607905). Karyopharm's related oral XPO1 inhibitor KPT-335 is currently in a potentially pivotal study in dogs with spontaneous non-Hodgkin's lymphomas.
Karyopharm's founder and Chief Scientific Officer Dr. Sharon Shacham commented, "At this AACR meeting, we are fortunate enough to share the results of our ongoing collaborative and internal work on the mechanisms of action and broad anti-tumor activity of SINE compounds for the treatment of a variety of malignant conditions. We believe that these data strengthen the basis for our two Phase 1 first-in-human clinical studies in adults with either solid tumor or hematologic malignancies, and support the future combination of SINEs with other forms of cancer therapy."
The AACR presentations are being made by academic collaborators studying the use of Karyopharm's novel SINEs, along with Karyopharm scientists, and cover the treatment of a variety of adult and pediatric solid tumor and hematologic malignancies as follows:

Karyopharm Therapeutics Inc. is a clinical-stage pharmaceutical company leading the development of small molecule modulators of nuclear transport. The company was founded by Drs. Sharon Shacham and Michael Kauffman in 2009 and has emerged as a leader in the new field of nuclear transport modulators. Karyopharm's selective inhibitors of nuclear export (SINE) function by trapping multiple tumor suppressor proteins in the nucleus, resulting in anti-cancer activity across multiple tumor types. In collaboration with many academic laboratories, SINEs, targeting the major nuclear exporter XPO1 (also called CRM1), exert robust anti-cancer activity in diverse preclinical models of cancer. The lead SINE KPT-330 is in two Phase 1 clinical studies for advanced solid tumor and hematologic malignancies. The related SINE KPT-335 is being evaluated as an oral treatment for dogs with Non-Hodgkin's Lymphoma, one of the most common canine cancers. The Company is also testing SINEs in autoimmune, viral and dermatologic disorders. Karyopharm Therapeutics is located in Natick, Massachusetts.
