Key data confirming Cantrixil kills ovarian cancer stem cells
Unique action of inhibiting pro-survival mechanisms and promoting pro-death mechanisms
SYDNEY, March 30, 2015 /PRNewswire/ — US-Australian drug discovery company, Novogen Ltd, (ASX:NRT; NASDAQ:NVGN) and its subsidiary, CanTx, Inc., and Yale University, on March 27 released pre-clinical data on experimental anti-cancer drug, Cantrixil. The data was presented as an oral presentation by Professor Gil Mor MD PhD of Yale Medical School to the 62nd Annual Scientific Meeting of the Society of Reproductive Investigation in San Francisco, CA.
In both in vitro and in animal studies, Cantrixil, has proved highly effective at killing human ovarian stem (tumor-initiating) cells, cells that otherwise are highly resistant to standard of care cytotoxic drugs and which generally are believed to be responsible for diseases recurrence following initial therapy. Researchers have been keen to understand how the active ingredient in Cantrixil, TRXE-002, is able to achieve this effect where other drugs have failed.
The data shows that Cantrixil specifically activates the JNK-Jun pathway leading to mitochondrial damage and the induction of genes associated with cell death (apoptosis). In addition, Cantrixil blocks the survival pathway pERK. The combination of these two cellular effects (down-regulation of pro-survival and up-regulation of pro-death pathways) provides a unique advantage to target chemo-resistant cancer stem cells.
Cantrixil is due to enter its first-in-man study in late-2015. The study will enroll patients with the terminal condition, malignant ascites, associated with late-stage abdominal carcinomatosis of various types of cancer, but mainly targeting ovarian cancer and colo-rectal cancer.
Cantrixil is a cyclodextrin envelope containing the active ingredient, TRXE-002. The construct has been designed as an intra-cavity chemotherapy to be injected directly into the peritoneal and pleural cavities without causing local irritation or toxicity. Its purpose is to achieve high drug levels in the environment in which the cancer is spreading through the migration of the cancer stem cells are spreading. The ultimate primary indication of Cantrixil to be sought is first-line therapy of early-stage cancers of the abdominal cavity (eg. ovarian, uterine, colo-rectal and gastric carcinomas). Cantrixil will enter the clinic in later-stage cancers where the abdominal carcinomatosis has resulted in the terminal condition of malignant ascites.
Cantrixil is owned by CanTx, Inc.
TRXE-002 is a small molecule cytotoxic belonging to a family of compounds whose anti-cancer function is based on various biological effects including inhibition of trans-membrane electron-transfer mechanisms. TRXE-002 is pan anti-cancer acting, resulting in caspase-dependent apoptosis of both stem cell-like cancer cells and their daughter cancer cells. The compound has a high therapeutic index with little cytotoxic effect on non-tumor cells.
About CanTx, Inc.
CanTx is a joint venture company between Novogen and Yale University. Novogen has licensed the drug candidate, TRXE-002, to CanTx for use in Cantrixil. CanTx is based in New Haven, CT.

About Novogen Limited
Novogen is a public, Australian-US drug-development company whose shares trade on both the Australian Securities Exchange (‘NRT’) and NASDAQ (‘NVGN’). The Novogen group includes US-based, CanTx Inc, a joint venture company with Yale University.
Novogen has two main drug technology platforms: super-benzopyrans (SBPs) and anti-tropomyosins (ATMs). SBP compounds have been designed to kill the full heterogeneity of cells within a tumor, but with particular activity against the cancer stem (tumor-initiating) cell.
The ATM compounds target the micro-filament component of the cancer cell’s cytoskeleton and have been designed to combine with anti-microtubule drugs (taxanes, vinca alkaloids) to produce comprehensive and fatal destruction of the cancer cell cytoskeleton.
The Company pipeline comprises two SBP drug candidates (TRXE-002, TRXE-009) and one ATM drug candidate (Anisina).
