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.
