Novogen Limited (ASX:NRT; NASDAQ: NVGN), Australian/US biotechnology company, announces that it has confirmed that its lead candidate product, TRXE-009, originally developed for the treatment of brain cancers, has been shown in pre-clinical studies also to be highly active against melanoma.
The Company believes this is an important breakthrough discovery for two reasons. The first is that it confirms that TRXE-009 is an important new potential treatment for melanoma, including for the treatment of secondary brain cancers due to melanoma, for which there currently are no effective therapies. The second is that it offers evidence for the first time of an hypothesized link between brain cancer and melanoma.
The link has long been considered a possibility because nerve cells and melanocytes (the melanin pigment-bearing cells in skin that lead to melanoma) have a common origin in the embryo known as the neural crest. This primitive tissue gives rise to the neural cells that go on to form the brain, spinal cord, and peripheral nerves, as well as cells that form the structures of the skull; melanocytes also come from this embryonic tissue. Up till now, no functional link has been found between brain cells and melanocytes, or between brain cancer and melanoma. TRXE-009 is the first compound to demonstrate the possibility of a common link, suggesting that is the first drug with the ability to identify cancers arising in cells that have the neural crest as their common origin.
