Issuance of this patent also completes the IP coverage for AB8939 and AML across all key geographic areas where AB8939 could be marketed, including Europe (patent EP 3253749), USA (US 10,570,122), Canada (CA 2975644), China (CN 107531685), South Korea (KR 10-2544132), Japan (JP 6713000), Hong Kong (HK 1243700), Israel (IL 253779), Australia (AU 2016214283), Russia (RU 2758259), Brazil BR (112017016883-9), Mexico (MX 377742), India (IN 480996), and South-Africa (ZA 2017/05537). AB8939 is a novel microtubule destabilizer, currently evaluated in early phase clinical trials for the treatment of AML. The phase 1 clinical trial of AB8939 has completed its first steps, consisting in determining the maximum tolerated dose following 3 consecutive days and then 14 consecutive days of AB8939 treatment. The next step will be to determine the maximum tolerated dose in the combination of AB8939 with Vidaza (azacitidine). In addition to patent protection, AB8939 is also eligible for regulatory data protection in Canada, preventing generic competition for a period of 8 years following initial approval.

AB8939 has also received orphan drug designation for AML from both the European Medicines Agency (EMA) and the US Food and Drug Administration (FDA). This orphan drug designation provides 10 and 7 years of market exclusivity in Europe and the United States, respectively, after product approval. A separate secondary medical use patent application was filed to protect the use of AB8939 for the treatment of AML with certain chromosomal abnormalities, which if granted, would extend AB8939 protection until 2044 in these sub-populations of AML patients.

About AB8939

AB8939 is a new synthetic molecule which jointly targets cancer cells, by destabilizing the microtubules essential for cell division, and cancer stem cells, by inhibiting enzymes (ALDH1A1 and ALDH2) essential for maintaining their physiological state and survival. The molecule ‘1-{4-[2-(5-ethoxymethyl-2-methylphenylamino)-oxazol-5-yl]phenyl}imidazolidin-2-one’ is the chemical name of AB8939. The intellectual property of AB8939 is 100% owned by AB Science.

The phase 1/2 DART study is an Australian investigator-initiated trial, led by Principal Investigators Professor David Ziegler and Dr Marion Mateos and sponsored by the Australian and New Zealand Children’s Haematology / Oncology Group (ANZCHOG) in collaboration with FivepHusion. The trial is designed to investigate Deflexifol monotherapy as a treatment for paediatric ependymoma and other childhood brain cancers. All major paediatric oncology centres in Australia are participating in the trial, and major trial funding has been provided by the Kids with Cancer Foundation, through Sydney Children’s Hospitals Foundation, and the Robert Connor Dawes Foundation. An abstract summarising the results of the Phase 1 component has been submitted to the Society of Neuro-Oncology for consideration of presentation at their international meeting in November.

Dr Christian Toouli, CEO and Managing Director of FivepHusion commented, "Completion of Part A of the DART study, and confirmation of a safe and tolerable phase 2 dose, are major milestones in our plans to develop Deflexifol as a potential treatment for paediatric ependymoma and other brain cancers. We thank the patients and their families for their participation in this trial, and our collaborators and partners for conducting this important study."

Deflexifol is an advanced clinical-stage, next-generation co-formulation of 5-fluorouracil (5-FU) and leucovorin (LV), a drug that significantly enhances 5-FU activity. Deflexifol has previously been evaluated in two successfully completed clinical trials in adults with a variety of solid tumours; the DART study is the first clinical evaluation of Deflexifol in paediatric patients. FivepHusion is harnessing the proven cytotoxic activity of 5-FU together with the unique, optimised attributes of the Deflexifol co-formulation to pursue Deflexifol development in a range of strategic solid tumour indications presenting with significant unmet medical needs, including paediatric ependymoma.

Ependymomas are rare central nervous system tumours (annual incidence of ~4 patients per million) that are more common in young children 0-4 years of age. The current standard treatment for ependymoma is surgery and radiotherapy, though relapse occurs in one third of all paediatric patients and is associated with a poor prognosis. Currently, there are no drugs approved for the treatment of ependymoma, presenting a significant unmet medical need for the development of safe and efficacious new treatments for this disease.

Previously, 5-FU has been reported as a promising drug candidate for the treatment of paediatric ependymoma by independent research groups1,2, and in a clinical trial conducted at the St Jude Children’s Research Hospital (Memphis, Tennessee, USA)3. Recently, independent studies have gained further insights into understanding the susceptibility of paediatric ependymoma to 5-FU4. Research by FivepHusion collaborators indicates that Deflexifol, as an optimised co-formulation of 5-FU and LV, may be efficacious against paediatric ependymoma and other brain cancers. Due to its improved safety, tolerability, and potentially superior anti-tumour efficacy, Deflexifol offers the exciting opportunity of addressing the limitations of current 5-FU formulations to enable development as potentially the first approved drug for ependymoma and possibly other brain tumours.

The purchase agreements provide certain registration rights, pursuant to which the Company has agreed to file a registration statement within 30 business days to register the resale of the common shares sold in the private placement and the common shares issuable upon exercise of the pre-funded warrants sold in the private placement.

The private placement is exempt from the registration requirements of the Securities Act under Section 4(a)(2) of the Securities Act in that the private placement is between an issuer and sophisticated investors not involving any public offering. The Company is relying on this exemption from registration based in part on representations made in the purchase agreements for the private placement, a form of which is attached to this Current Report on Form 8-K as Exhibit 10.1.

The pre-funded warrants are exercisable at any time after their original issuance until the tenth anniversary of their original issuance. At any time during the last 90 days of the term, the holder may exchange the pre-funded warrant for, and the Company will issue, a new pre-funded warrant for the number of common shares then remaining under the pre-funded warrant. The pre-funded warrants will be exercisable, at the option of each holder, in whole or in part (but not for less than a common share) by delivering to the Company a duly executed exercise notice and by payment of the aggregate exercise price; provided that any exercise of the pre-funded warrants must be for at least 50,000 common shares (or, if less, the remaining common shares available for purchase under the pre-funded warrants). A holder will not be entitled to exercise any portion of any pre-funded warrants that, upon giving effect to such exercise, would cause the aggregate number of the Company’s common shares beneficially owned by the holder (together with its affiliates and certain attribution parties) to exceed 9.99% (or, 61 days after a written notice from such holder, any other percentage not in excess of 19.99%) of the number of the Company’s common shares outstanding immediately after giving effect to the exercise, as such percentage ownership is determined in accordance with the terms of the pre-funded warrants. The exercise price per common share purchasable upon the exercise of the pre-funded warrants is CHF 0.08 per share, subject to customary adjustments. In lieu of making cash payment of the aggregate exercise price, a holder may elect to exercise the pre-funded warrants on a cashless basis. However, if the Company, at the time of receipt of an exercise notice electing cashless exercise, (i) does not, or has reason to believe that the Company does not, have a sufficient amount of freely distributable equity to fund the nominal value of the number of common shares the Company would be required to deliver upon such cashless exercise, and (ii) (x) holds common shares representing more than 2% of its share capital registered in the commercial register at that time (the "Minimum Stock") in treasury, then the Company will not be obligated to (but may) deliver more than such number of common shares to the holder as exceeds the Minimum Stock or (y) holds up to the Minimum Stock in treasury, then the Company will not be obligated to deliver any common shares to the holder. The exercise notice will be deemed to be null and void to the extent the holder receives fewer common shares than to which such exercise notice relates. In the event of (i) a sale, lease or other transfer of all or substantially all of the Company’s assets, (ii) a merger or consolidation involving the Company in which the Company is not the surviving entity or in which the Company’s outstanding share capital is converted into or exchanged for shares of capital stock or other securities or property of another entity, or (iii) any sale by holders of the Company’s outstanding voting equity securities in a single transaction or series of related transactions of shares constituting a majority of the Company’s outstanding combined voting power, and (x) if the consideration received by the Company’s shareholders consists solely of cash and/or marketable securities, then holders of the pre-funded warrants will be deemed to have exercised their pre-funded warrants (without regard to the exercise limitations described above) immediately prior to the closing date of such transaction or (y) if the consideration received by the Company’s shareholders does not consist solely of cash and/or marketable securities, then the Company will cause the successor or surviving entity to assume the pre-funded warrants. Subject to applicable laws, the pre-funded warrants may be offered for sale, sold, transferred or assigned without the Company’s consent. The pre-funded warrants are governed by the laws of Switzerland. The foregoing description of the pre-funded warrants does not purport to be complete and is qualified in its entirety by reference to the form of pre-funded warrant, which is attached to this Current Report on Form 8-K as Exhibit 10.2.
