Exhibit 4.7

4 December 2014

Triaxial Pharmaceuticals Pty Ltd (Triaxial)

Dear Shareholders,

Amendment to Convertible Note Deed Poll

I refer to the Convertible Note Deed Poll (Deed) signed by Novogen Limited (Novogen or Company) on the 4^th of November 2013, which superseded the precedent Loan Agreement between Triaxial shareholders and Novogen.

The Deed in which you are referred to as Convertible Note Holders (Note Holders) was signed by Novogen with the intention to extinguish the liability created by the Loan Agreement and transform your interest as creditor into an equity interest in Novogen, provided that the Company achieved defined milestones established in the schedule of the Deed (Milestone).

However, it appears that the Company’s auditors, Grant Thorton, have formed the view that some clauses in the Deed are at the origin liability. Clause 2.7(a)(ii), 2.8 and 4 (Liability Clauses) create a liability by qualifying the Convertible Note as a debt and by allowing you to redeem for cash the remaining value of your Convertible Note that has not been converted yet, if after 3 months of achieving a Milestone the convertible note has not been converted into the corresponding amount of equity as set out by the Milestone.

The Liability Clauses maintain the liability of the Company towards the Note Holders and affects considerably the debt of the Company.

Considering the recent letter received from Nasdaq (See “Novogen Received Nasdaq Deficiency Notice” announced on the 12^th of November 2014), the Company needs to increase its equity to regain compliance with Nasdaq listing rule.

The Liability Clauses affect directly Novogen’s equity and this is why I propose that the Deed Poll is amended by deleting these clauses to finally extinguish the debt component of the transaction.

A Deed of Amendment (Amendment) has been prepared and is attached with this letter.

Please read it carefully and if you agree to the proposed Amendment, sign the Approval Page of this letter where your name is indicated.

Once the approval of all the Note Holders has been collected, the Company will sign the Amendment.

You can contact me at any time if you need clarification regarding this letter or the Amendment.

Yours faithfully,

Dr. Graham Kelly

Chairman and CEO
