Myriad Pharmaceuticals Announces the Identification of an IND Candidate for the Treatment of Cancer, Obesity, and Diabetes

Significant Commercial Potential for An Exciting New Drug Candidate Targeting IKK Epsilon


SALT LAKE CITY, Oct. 13, 2009 (GLOBE NEWSWIRE) -- Myriad Pharmaceuticals, Inc. (Nasdaq:MYRX) today announced the identification of an Investigational New Drug (IND) candidate targeting a novel molecular target, the protein kinase IKK epsilon.

A recent publication in the September issue of Cell from the laboratory of Dr. Alan Saltiel (Chiang et al, (2009) Cell 138, 961-975) identified IKK epsilon as a central regulator of chronic inflammation, obesity and diabetes. Based upon that Cell paper, inhibitors of IKK epsilon are expected to have significant potential for the treatment of obesity, diabetes and associated diseases. This conclusion was reiterated in an editorial by Dr. Jerrold Olefsky of the University of California, San Diego.

Myriad Pharmaceuticals' IKK epsilon antagonist and IND candidate, MPI-0485520, is a selective and potent inhibitor of IKK epsilon, with high oral bioavailability and demonstrated on-target, in vitro and in vivo biological activity.

Myriad Pharmaceuticals' IKK epsilon program was originally launched to exploit the potential of IKK epsilon as a novel oncology target. Published reports and internal research at Myriad Pharmaceuticals have demonstrated that IKK epsilon expression is amplified in human breast, ovarian, and prostate tumor cells. Overexpression of IKK epsilon transforms cells in culture and conversely, reduction of IKK epsilon expression or inhibition of activity inhibits tumor cell growth.

"MPI-0485520 represents a potential very large commercial opportunity for Myriad Pharmaceuticals," said Adrian N. Hobden Ph.D., President and CEO of Myriad Pharmaceuticals. "IKK epsilon is, perhaps, the most exciting new target for the treatment of obesity and diabetes that has emerged in the last ten years. It was opportune that Myriad Pharmaceuticals' scientists have developed expertise with this important target and have been studying MPI-0485520 for some time."

MPI-0485520 is a product of Myriad Pharmaceuticals' internal research and development efforts. Myriad Pharmaceuticals expects to seek to partner MPI-0485520 for clinical development in the fields of obesity and diabetes but intends to pursue by itself the development of this and other compounds in the IKK epsilon program for the treatment of cancer.

About obesity, diabetes and cancer

More than 25% of Americans are obese with an estimated annual cost to the healthcare system of more than $140 billion. Diabetes affects more than 7% of the American population and direct costs to the healthcare system exceed $110 billion annually. The National Cancer Institute reports that obesity leads to one in five cancer deaths in women and one in seven cancer deaths in men.

Myriad Pharmaceuticals' Clinical Pipeline

MPC-4326

MPC-4326 (bevirimat dimeglumine) is Myriad Pharmaceuticals' investigational new drug being developed as an oral treatment of human immunodeficiency virus 1 (HIV-1) infection. MPC-4326 is a potent small-molecule that acts as a viral maturation inhibitor and is a first-in-class drug candidate with a novel mechanism of action. New drugs with novel mechanisms of action are needed to combat the evolution of HIV drug resistance to the currently available therapies. MPC-4326 has been granted Fast Track designation by the U.S. Food and Drug Administration. Myriad Pharmaceuticals expects to initiate a 24-week, controlled, two-arm efficacy study (Phase 2b) of MPC-4326 in HIV treatment-experienced patients in the fourth quarter of 2009.

Azixa (MPC-6827)

Azixa is Myriad Pharmaceuticals' most advanced cancer drug candidate. Azixa is currently in three Phase 2 studies for the treatment of glioblastoma multiforme and metastatic melanoma. Azixa has two unique distinguishing activities. In non-clinical studies, Azixa has demonstrated the ability to effectively cross the blood-brain barrier and accumulate in the brain at levels as much as 3000% of that in plasma. Also, Azixa does not appear to be subject to multiple drug resistance (MDR) mechanisms. Frequently primary and secondary tumors develop multiple drug resistance and stop responding to the chemotherapeutic agents used today, thus significantly limiting their effectiveness and leaving patients few additional therapeutic options. Glioblastoma multiforme is diagnosed in about 20,000 Americans each year. Metastases in the brain are a very common problem in late stage cancers with an annual US incidence of approximately 170,000 patients.

MPC-3100

MPC-3100 is currently in Phase 1 clinical studies. MPC-3100 is a novel, fully-synthetic, orally-bioavailable, small-molecule inhibitor of Heat shock protein 90 (Hsp90). Hsp90 is a proven target for cancer treatment. Early natural product inhibitors of Hsp90 demonstrated activity in several human cancer clinical studies, including studies of Her2+ breast cancer, multiple myeloma and gastric cancers. However, these compounds have also demonstrated significant toxicity, which appears not to be related to inhibition of Hsp90. Unlike these molecules, MPC-3100 is a fully-synthetic, small molecule which is orally-bioavailable and has very encouraging, non-clinical safety and efficacy data. MPC-3100 has the potential to treat a wide range of cancers.
