ASX:NRT   NASDAQ:NVGN   Novogen Ltd (Company)   ABN 37 063 259 754     Capital Structure   Ordinary Shares on issue:   250 M       Board of Directors   Dr Graham Kelly Chairman & Executive Director   Steve Coffey Non Executive Director   John O’Connor Non Executive Director   Prof Peter Gunning Non Executive Director		ASX RELEASE 4 March 2015   US STUDIES CONFIRM ABILITY OF TRXE-009 TO KILL BRAIN CANCER STEM CELLS   •    Potent killing of highly resistant adult and pediatric brain cancer cells   •    Opportunity to effect prevention of recurrence of brain cancer   4 March 2015, Sydney, Australia: Novogen Limited (ASX:NRT; NASDAQ:NVGN): Australian/US biotechnology company, Novogen Limited, today announces that it has confirmed that one of its lead candidate products, TRXE-009, is showing the potential to become an important new therapy in the fight against adult and pediatric brain cancer.   The latest study looked at the ability of TRXE-009 to kill a library of patient-derived cell cultures from subjects with glioblastoma multiform (GBM). The cells were cultured under conditions that promote cancer stem cell growth. These stem-like cancer cells are believed to be responsible for chemotherapy resistance and tumor recurrence.   Killing these highly-resistant GBM cancer stem cells is considered to be a fundamental requirement to successfully treating this highly destructive disease.   All patient derived cancer cells represented in the library responded to TRXE-009 at clinically relevant doses, suggesting a strong therapeutic potential.   The studies were conducted by Drs John Boockvar and Marc Symons at the Feinstein Institute for Medical Research (Feinstein) and with which Novogen is forging a strong collaboration to oversee advancing TRXE-009 into the clinic for adult and pediatric brain cancers.   These findings join with other recently announced pre-clinical studies showing that TRXE-009 is highly cytotoxic of chemo-resistant pediatric brain cancers such as Diffuse Intrinsic Pontine Glioma (DIPG) as well as other pediatric neural and neural crest-derived tumors (i.e. medulloblastoma and neuroblastoma, respectively). Together, these studies suggest that TRXE-009 is a unique drug candidate in preferentially targeting tumors with a common embryonic origin in neural/neural crest cells.   The next step in this drug’s development is to confirm it’s ability to cross the blood-brain barrier, a key filtering mechanism that effectively blocks the majority of chemotherapic drugs from reaching brain tissue.   TRXE-009 was designed to cross the blood-brain barrier and has been formulated as a proprietary drug product known as Trilexium. It is anticipated that Trilexium will have application in the treatment of cancers both with and without brain involvement. Trilexium is due to enter a Phase 1 study in early-2016.

In conjunction with Feinstein, alternative means of delivering TRXE-009 to the brain are under investigation including direct injection into the brain cancer by the process known as convection-enhanced delivery, and the use of lipid brain-targeting particles injected intravenously.

Dr Graham Kelly, Novogen Group CEO, said, “TRXE-009 has been a drug development success story, thanks to a team led by Andrew Heaton PhD and Eleanor Ager, PhD. The TRXE-009 story started with the discovery of a compound that was highly cytotoxic against GBM brain cells that came from patients who had failed to respond to Temozolomide, the only standard of care chemotherapy for GBM; it then showed itself to be an equally effective killer of GBM cancer stem cells; it also is highly active in vitro against a range of pediatric brain cancer cells that are notoriously resistant o chemotherapy; it has been designed to cross the blood-brain barrier; it shows little toxicity against normal human brain cells (astrocytes) in vitro; in its parenteral delivery form, the Trilexium drug-product is highly active in animal models of xenografted human tumors, including GBM, and is reasonably well tolerated. So far it has ticked every box asked of it.”

“The urgent need to find a successful treatment for devastating cancers such as primary and secondary brain cancers in adults and children is what is driving our collaboration with Feinstein to bring TRXE-009 into the clinic,” Kelly added.

About Novogen Limited

Novogen is a public, Australian 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, including the cancer stem cells. The molecular target is a trans-membrane electron-transfer pump mechanism oncogene that is common to all cancer cells. Cells die by respiratory distress and mitochondrial disintegration.

The ATM compounds target the micro-filament component of the cancer cell’s cytoskeleton and have been designed to combine with anti-microtubular drugs (taxanes, vinca alakaloids) to produce comprehensive and fatal destruction of the cancer cell cytoskeleton.

The Company pipeline comprises three SBP drug candidates (TRXE-002, TRXE-009, TRXE-0025) and one ATM drug candidate (‘Anisina’).

About TRXE-009

TRXE-009 is an SBP compound generated by the Company’s VAL-ID (Versatile Approach to Library-based Iterative Design) drug discovery process, with structure-activity relationship driving design based on activity against brain cancer stem cells and the known required chemical criteria to facilitate passage across the blood-brain barrier.

About Trilexium

Trilexium is the name give to a proprietary parenteral formulation of TRXE-009 selected for its ability to maximize systemic drug delivery and effectiveness in pre-clinical rodent models of human cancer.
