LOGO

Conventional cancer therapy

Almost all forms of human cancer are thought to comprise a majority of standard cancer cells (red) and a small (<0.01%) minority of cancer progenitor cells known as cancer stem cells (yellow).

• With some notable exceptions (e.g. melanoma, mesothelioma, glioblastoma), the bulk of standard cancer cells in a tumour have a reasonably high degree of sensitivity to radiation or chemotoxic drugs, typically leading to shrinkage of the tumour (‘REMISSION’).

• Cancer stem cells (yellow), however, are almost completely insensitive to radiotherapy and chemotherapy and remain unaffected by anti?cancer therapy.

• In time, the cancer stem cells reproduce to create a new tumour, this time populated by cancer cells (brown) inheriting the radio?resistance and chemo?resistance of the cancer stem cells (‘RECURRENCE’).

• The RECURRENT cancer typically is more aggressive and now resistant to all standard anti?cancer drugs.

Comprehensive anti?cancer therapy

Short term Remission Long?term Remission

??Comprehensive anti?cancer therapy refers to the ability to kill both standard cancer cells and cancer stem cells with first?line therapy, in this way avoiding the regeneration of cancer cell populations with high?level multi?drug resistance mechanisms.

??It is ‘comprehensive’ as it aims to provide long?term remission of cancer through effective removal of the source of the cancer, not just dealing with the cells that come from that source.

Strategy

Company Strategy: To develop the first comprehensive cancer therapy capable of killing both standard tumour cells and cancer stem cells

?CS?6 is Novogen’s first super?benzopyran drug candidate. CS?6 is:

?highly active in the laboratory against all forms of human cancer so far tested; ?most active against glioblastoma multiforme cells (main form of brain cancer); and ?highly active against (ovarian) cancer stem cells (nanomolar levels).

?Novogen aims to bring CS?6 to market as a treatment for late?stage brain cancer and late?stage ovarian cancer.

?Ability to destroy both cancer stem cells and their chemo?resistant daughter cells is a game changer as

no other drug (currently approved or in development ) knocks out both the highly resistant cancer stem cells and

their daughter cancer cells in a selective manner with acceptable side?effects.
