NEWTON, Mass., March 18, 2015 (GLOBE NEWSWIRE) -- Karyopharm Therapeutics Inc. (Nasdaq:KPTI), a clinical-stage pharmaceutical company, today announced that five abstracts describing the company's PAK4 allosteric modulators (PAMs) have been selected for presentation at the 2015 Annual Meeting of the American Association for Cancer Research (AACR) taking place April 18-22 in Philadelphia. These preclinical abstracts, which represent both company and investigator-sponsored research, present data related to intercellular PAMs effects on K-Ras and WNT/ß-catenin signaling pathways and the characterization of single agent antitumor activity. Detailed results from these studies will be presented at the conference.
"We are pleased to be presenting updated research on Karyopharm's PAK4 allosteric inhibitors at the AACR annual meeting," said Sharon Shacham, PhD, MBA, President and Chief Scientific Officer of Karyopharm. "Presentations on our PAK4 inhibitors include effects on key signaling pathways along with activity in several solid tumor models, supporting further development of these novel oral PAMs."
Abstracts related to Karyopharm's novel, selective, oral small-molecule PAMs include:

P21-Activated Kinase 4 (PAK4) is a member of the PAK family of proteins that regulate cell survival, cell division and apoptosis. PAK4 is a key downstream effector of the K-Ras pathway and mediates cell motility, proliferation, and survival. Karyopharm has identified selective, novel, orally-bioavailable small molecule PAK4 allosteric modulators (PAMs) with demonstrated anti-tumor activity both in vitro and in vivo. Karyopharm's lead PAMs have shown promising results in many preclinical models for the treatment of a wide variety of cancers.
