MARKET RELEASE 24 June 2015
ANISINA ON TRACK TO ENTER THE CLINIC IN 2016
Anisina delivers potent anti-tumor effect in vivo
Human melanoma tumors respond to Anisina treatment
Potent anti-cancer effect with no observed toxicity
Sydney, Australia, 24 June 2015: US-Australian drug discovery company, Novogen Limited (NRT: ASX; NVGN: NASDAQ) (Company), announced today that its candidate cytotoxic chemotherapy drug, Anisina, has proved an effective anti-cancer agent in animals, the result of which it now has been fast-tracked by the Company to come into the clinic.
Anisina targets the cytoskeleton of cancer cells. This is the same target of the most widely used chemotherapy drugs in cancer, the taxanes and vinca alkaloids. These latter drugs are standard of care for some of the most common cancers in adults embracing both solid cancers (breast, ovary, prostate, lung, bladder, testicle) and non-solid cancers (acute leukaemias, Hodgkins Disease), as well as in pediatric cancers (neuroblastoma, Wilms tumor). Beyond these approved uses, they are widely used off-label across most forms of cancers following failure of standard of care drugs.
Despite their common use, the taxanes and vinca alkaloids come with the significant disadvantages of (i) being non-selective, resulting in significant side-effects, (ii) not working in many forms of cancer, and (iii) readily inducing resistance in cancer cells.
There remains a significant clinical need to improve on both the efficacy and safety of these commonly used drugs. Novogen believes that Anisina has the features to meet that need across a range of cancer types. |
The taxanes and vinca alkaloids target a structural component of the cytoskeleton known as the microtubule. De-stabilizing this structure prevents the cancer cell from dividing and promotes its death.
Anisina is a first-in-class drug candidate that targets the other main structural component of a cancer cell known as the microfilament.
There is a 20-year history of attempts to produce drugs against microfilaments. The commercial success of the taxanes and vinca alkaloids in the 1970s validated the cancer cells cytoskeleton as a target for anti-cancer drugs, making the destruction of the microfilaments an obvious alternative drug target. These attempts failed because of the inability to limit the destructive effect to cancer cells microfilaments, with loss of muscle function being a pronounced toxic side-effect.
The breakthrough came 10 years ago with the discovery by Professor Peter Gunning and Dr Justine Stehn at the University of New South Wales (Sydney, Australia) of the role of a structural protein known as Tmp3.1 in the function of microfilaments. Cancer cells are far more reliant on Tmp3.1 for the integrity of their microfilaments than are normal cells. Anisina specifically targets Tmp3.1, destroying the microfilaments of cancer cells with proportionally much less effect on normal cells.
Compared to the taxanes and vinca alkaloids, Anisina offers three potential advantages, viz. (i) being more selective against cancer cells, (ii) being able to kill cancer cell types inherently insensitive to taxanes and vinca alkaloids, and (iii) not being subject to the same drug-resistance mechanisms that affect the taxanes and vinca alkaloids.
Ahead of bringing Anisina into the clinic, Novogen has focused on three indications melanoma, prostate cancer, neuroblastoma with animal studies underway in each indication in support of IND applications over the next 9 months.
We have previously announced that Anisina is active in vitro against human melanoma cells, a cancer that is relatively insensitive to the taxanes and vinca alkaloids. We also have announced that Anisina kills human melanoma cells irrespective of their mutational status.
Todays announcement concerns the important key step of establishing a significant anti-tumour effect in vivo. The study reported here is with melanoma; the neuroblastoma animal studies are being reported to a scientific conference on July 13; the prostate cancer studies will be reported shortly after that.
Mice bearing the human malignant melanoma cell line A-375 (BRAF-mutant) were treated with Anisina either intravenously (60 mg/kg/twice weekly) or orally (100 mg/kg/daily). Both dosing regimens delivered a significant anti-tumor effect with no observed toxicity.
Justine Stehn PhD, Novogen Anti-Tropomyosin Program Director, said, This result clears the way for Anisina to enter the clinic. The potent effect observed here of the drug on a cancer as difficult to treat as malignant melanoma, combined with the lack of any obvious toxicity of the drug, justifies our earlier speculation that destroying a cancer cells microfilaments would yield an equivalent therapeutic benefit to destroying the microtubules, but without the toxicity of the latter.
Large-scale manufacture of the compound now is underway with a target of being in a first-in-man study in 2Q16, Stehn added.
About Novogen
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 drug technology platforms yielding drug candidates that are first-in-class with potential application across a broad range of degenerative diseases. In the oncology field, the ultimate objective is to see both drug technologies used in combination as first-line therapy across most forms of cancer, with the objective of preventing tumor recurrence. This objective is based on a strategy of achieving comprehensive destruction of the full hierarchy of cells within a tumor with the super-benzopyran technology platform killing the tumor-initiating cells and the anti-tropomyosin technology, combined with vinca alkaloids, to deliver a potent chemical debulking effect on their daughter cells.
