Jan 7, 2009

New Canaan, CT, January 7, 2009   Marshall Edwards, Inc. (NASDAQ: MSHL) today announced that it has been granted an Investigative New Drug (IND) approval by the United States Food and Drug Administration to undertake clinical studies with triphendiol as a chemosensitising agent in combination with gemcitabine.  This approval will enable a Phase Ib study of triphendiol in combination with gemcitabine in patients with unresectable, locally advanced or metastatic pancreatic and bile duct cancers.
 
About Triphendiol
 
Triphendiol (NV-196) is an investigational drug in the Marshall Edwards, Inc., oncology drug pipeline, currently being developed as an orally-delivered chemosensitizing agent, intended for use in conjunction with standard chemotoxic anti-cancer drugs for the treatment of late stage pancreatic cancer, cholangiocarcinoma, and melanoma.  Triphendiol was granted orphan drug status by the U.S. Food and Drug Administration for pancreatic cancer and cholangiocarcinoma in January 2008 and for treatment of stage IIb-IV malignant melanoma in February, 2008.

Triphendiol is broadly cytostatic and cytotoxic against most forms of human cancer cells in vitro, and has been shown to cause cell cycle arrest (or stop cells increasing in number) and to induce apoptosis (or initiate programmed cell death) in various cancer cell lines.  Biological studies suggest a mechanism of cytotoxicity that involves mitochondrial depolarization and downregulation of XIAP.  It exhibits high selectivity, little effect on non-tumor cells and no observable toxicity in animals at therapeutically effective doses.  In human studies conducted in Australia, no adverse events or side effects have been reported when administered to volunteers.

About Marshall Edwards, Inc.

Marshall Edwards, Inc. is a specialist oncology company focused on the clinical development of novel anti-cancer therapeutics.  These derive from a flavonoid technology platform, which has generated a number of novel compounds characterized by broad ranging activity against a range of cancer cell types with few side effects.  The combination of anti-tumor cell activity and low toxicity is believed to be a result of the ability of these compounds to target an enzyme present in the cell membrane of cancer cells, thereby inhibiting the production of pro-survival proteins within the cell.  Marshall Edwards, Inc. has licensed rights from Novogen Limited (ASX: NRT  NASDAQ: NVGN) to bring three oncology drugs - phenoxodiol, triphendiol and NV-143 - to market globally.  The Company's lead investigational drug, phenoxodiol, is in a Phase III multinational multi-centered clinical trial for patients with recurrent ovarian cancer.  More information on the trial can be found at http://www.OVATUREtrial.com.
 
Marshall Edwards, Inc. is majority owned by Novogen (ASX: NRT, NASDAQ: NVGN), an Australian biotechnology company that is specializing in the development of therapeutics based on a flavonoid technology platform.  Novogen is developing a range of therapeutics across the fields of oncology, cardiovascular disease and inflammatory diseases.  More information on phenoxodiol and on the Novogen group of companies can be found at www.marshalledwardsinc.com and www.novogen.com.
