SALT LAKE CITY, Sept. 16, 2010 (GLOBE NEWSWIRE) -- Myrexis, Inc. (Nasdaq:MYRX), a biotechnology company focused on discovering, developing, and commercializing novel treatments for cancer, today announced it will present a poster at the Cancer and Metabolism: Pathways to the Future meeting in Edinburgh, Scotland, as well as two additional posters at the 22 nd European Organisation for Research and Treatment of Cancer (EORTC), National Cancer Institute (NCI) and American Association for Cancer Research (AACR) Symposium on "Molecular Targets and Cancer Therapeutics" November 16-19, 2010, in Berlin, Germany.

The posters will highlight key findings from Myrexis' cancer metabolism inhibitor (CMI) program, including the Company's potential best-in-class Nampt inhibitor, MPC-9528, which is currently in preclinical IND studies and has demonstrated flexible dosing and dramatic tumor regression across multiple tumor types.

About MPC-9528

MPC-9528 is an orally-bioavailable, small molecule Cancer Metabolism Inhibitor (CMI) discovered by Myrexis that is currently in preclinical development for the treatment of a variety of cancers.  MPC-9528 potently and selectively inhibits nicotinamide phosphoribosyltransferase, or Nampt, an enzyme critical for converting nicotinamide into nicotinamide adenine dinucleotide (NAD). Cellular processes such as glucose metabolism, DNA repair and gene expression require and consume NAD. Cancer cells have increased NAD requirements and are highly sensitive to NAD depletion.  Blocking the Nampt-NAD pathway severely inhibits cancer cell metabolism, resulting in energy deprivation and ultimately cell death. In non-clinical models, MPC-9528 causes dramatic tumor regressions across multiple tumor types. 

Normal healthy human cells produce NAD by a number of different pathways. Additional research however, indicates that that many cancers, as much as 40% of all cancers, lose the ability to produce NAD by these alternative pathways and become absolutely dependent upon Nampt activity.  Patients with these tumor types may be particularly responsive to MPC-9528 therapy and a simple companion diagnostic could be used to easily identify these patients.  MPC-9528 is primed to be the best-in-class Nampt inhibitor with potential for treating a wide variety of cancers.
