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, 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.

Under U.S. law, a new drug cannot be marketed until it has been investigated in clinical trials and approved by the FDA as being safe and effective for the intended use.
