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 has licensed rights from Novogen Limited (ASX: NRT NASDAQ: NVGN) to bring four oncology drugs - phenoxodiol, triphendiol, NV-143 and NV-128 - to market globally.

Marshall Edwards is majority owned by Novogen Limited, 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.
