Noxopharm Limited (ASX: NOX) (‘Noxopharm’ or the ‘Company’) today releases its Appendix 4C for the quarter ended 30 June 2019, as well as providing guidance for the next 12 months. This report is for the Noxopharm Group covering both Noxopharm Limited and its majority-owned subsidiary, Nyrada Inc.

Much of the Company’s efforts and resources have been and will continue to be directed to the clinical development of our first clinical-stage asset, Veyonda®. Veyonda® has a range of lethal effects within cancer cells and in the surrounding cancer microenvironment that include immune-stimulating effects. The breadth of these effects means that Veyonda® may add-to or enhance the efficacy of a number of different types of anti-cancer treatments. Together with the good tolerability profile observed to-date in clinical studies combining Veyonda® with various forms of radiotherapy or chemotherapy, the Company is confident Veyonda® has the potential to be an extremely versatile cancer treatment.

1.  Veyonda® Clinical StrategyThis versatility means that the Company is, in many ways, spoilt for choice. A challenge that is preferable to having too few options, but one that still needs to be managed. Our approach to this has been to focus the clinical development program as much as possible, whilst ensuring we maintain enough diversity in our program to manage technological and commercial risk. In always following the valid leads that our scientific work discovers, the thinking behind our clinical strategy can be summarized under three key action statements:

  • Focus on one cancer where the unmet-need burden for the community is huge e.g. prostate cancer
  • Focus on one cancer where the challenge due to too few treatment options is huge e.g. sarcoma
  • In focusing on prostate cancer and sarcoma, follow the technological mega-trends e.g. immuno-oncology and advancement in radiotherapeutics

This thinking has led us to two key strategic priorities:

  1. Establish Veyonda® as an essential adjunct to radiotherapy1 in the treatment of prostate cancer2
  2. Broaden the clinical value of Veyonda® by improving outcomes in sarcoma3 and increasing response-rates with immuno-oncology agents

2.  Veyonda® Clinical ProgramIn progressing towards our two strategic priorities, the Company currently is conducting, supporting or in late stages of planning for four clinical trials:

  1. With radiotherapy: the DARRT-1 trial, the LuPIN trial and the DARRT-2 trial
  2. With chemotherapy: the CEP-2 trial
2.1. DARRT-1
  The Direct and Abscopal Response to RadioTherapy -1 trial combines low dose, external beam radiotherapy delivered over 5-8 days with Veyonda® administered twice daily for 13-16 days to treat men with late-stage metastatic castration-resistant prostate cancer (mCRPC). During the June quarter we announced that this treatment combination led to lasting disease control, with 57% of the 14 patients in the first phase of the trial remaining progression free over six months. Pain responses also were encouraging with two patients being completely free of pain at 6 months. We also announced that enrolment of the second cohort of 12 patients was completed in May, meaning that we anticipate topline 12-week and 24-week follow-up results for this cohort to be announced in August and November of this year respectively. We look forward to full disclosure of the trial results at an international scientific congress in H1 2020.
   
2.2. LuPIN
  The Lu-PSMA and IdroNoxil trial is investigating the combination of 177Lu-PSMA-617 and Veyonda® in the treatment of patients with late-stage mCRPC. Treatment includes up to six, 42-day treatment cycles consisting of an intravenous injection of 177Lu-PSMA on day 1 of the cycle and daily administration of Veyonda® on days 1-10. Initially 16 patients were recruited to the trial (8 patients treated with 400 mg daily and 400 mg twice daily of Veyonda, respectively). This was subsequently expanded to include another 16 patients (400 mg twice daily) and in the June quarter the company announced that the trial is being expanded again by recruiting a further 24 patients who will be treated with 600 mg twice daily. This decision was driven by our desire to study the 1200 mg dose (target dose for our phase 2, DARRT regimen trial) and by the encouraging data pertaining to the first 16 patients in the trial. Prostate-specific antigen (PSA) response-rates in these patients were high, with 69% of patients achieving a response. Overall survival trends in the study also are encouraging, with 81% of the first 16 patients still alive following a median follow-up of 12 months. This compares favourably with background epidemiological data suggesting that patients with extensively treated, end-stage mCRPC currently have a median life-expectancy of 12-months or shorter4.
   
2.3. DARRT-2
  Planning is well underway for a phase 2, randomized, controlled trial of the DARRT regimen (low dose radiotherapy plus Veyonda®) in mCRPC. A range of potential designs will be discussed with world renowned radiation oncologists, medical oncologists and nuclear medicine physicians in the U.S. and in Australia at upcoming advisory boards planned for Q3 2019. This trial is intended to address questions that will lay the foundation for a range of potential phase 2/3 trial designs in prostate cancer, enabling the company to carefully select and sequence indications to target for regulatory approval.
   
2.4. CEP-2
  The Chemotherapy Enhancement Program – 2 trial will combine Veyonda® with doxorubicin to treat adult patients with metastatic soft tissue sarcomas (mSTS). mSTS is a rare but devastating group of over 70 different subtypes of cancers that has seen few advances in pharmaceutical treatment in the last 50 years. The company has worked with internationally acclaimed clinical experts in the U.S. to develop the protocol for this trial which will be conducted in the U.S. Currently the Company is in dialogue with the Food and Drug Administration (FDA) with the goal of achieving Investigational New Drug (IND) status in the U.S before the end of the year. The Company also is in preparation to apply to the FDA for Orphan Drug Designation in H2 2019. If successful, this will open access to a range of regulatory and financial benefits that will greatly assist the Company to develop Veyonda® for sarcoma.5

3.  Non-Clinical Programs

3.1. Preclinical research
  The Company’s preclinical research program is currently focused on complementing the Veyonda® clinical development program. This includes research to support regulatory requirements such as characterizing its pharmacological properties (e.g. pre-clinical safety) and research to inform therapeutic indications. The research informing therapeutic indications is focused on three main areas:
  3.1.1. Mechanisms of radio-sensitisation and abscopal effects
    Encouraging results from studies exploring the abscopal effect accrued in the June quarter and the Company anticipates disclosing and publishing these findings as soon as remaining confirmatory studies conclude. We expect these studies to conclude in Q4 2019.
  3.1.2. Immuno-oncology effects
    During the June quarter the Company disclosed its discovery that the active ingredient in Veyonda®, idronoxil, promotes both the innate and the adaptive immune systems, activating natural killer (NK) cells and increasing numbers of CD4 and CD8 lymphocytes. The Company believes that these effects are associated with idronoxil activating the STING (Stimulating Interferon Genes) pathway, a self-defence pathway that alerts the innate immune system to cells with damaged DNA e.g. virally infected cells or cancer cells. There currently is considerable interest in the pharmaceutical industry in drugs that trigger STING (known as STING agonists) as a means of boosting the overall low response rates to immuno-oncology drugs. Current STING agonists under development on the whole have been limited to being injected directly into individual tumours. This is because of serious safety concerns related to their mechanism of action that precludes dosing them in a way that exposes the whole body to their pro-STING effect. Veyonda® does not have this limitation, a fact that has been borne out by its high level of tolerability in clinical trials to date. The Company regards this as a major development, with Veyonda® representing the first known means of delivering a well-tolerated STING agonist able to reach all cancer cells throughout the body. More work is underway to better characterize the nature and extent of the molecule’s STING effects, with the goal of informing designs for combination immuno-oncology trials.
  3.1.3. Sarcoma
    With over 70 subtypes of soft tissue sarcoma, our work has focused on exploring how consistently Veyonda® can be expected to work across these subtypes and how well Veyonda® can be expected to work in combination with various chemotherapeutic agents. We remain encouraged by the results we have obtained and continue confidently with planning for CEP-2.
     
 3.2. Manufacturing and dosage form 
  The maturation of Veyonda® as a clinical candidate is being matched by increases in data generation pertaining to the drug substance (e.g. strength, quality, purity) and the drug product (e.g. detailed description of manufacturing processes). Progress also has been made on our 600 mg dosage form and on development of our placebo suppositories which will be identical in appearance to Veyonda® itself to ensure adequate blinding in our phase 2 and phase 3 trials. 
     
3.3. Drug Discovery
  With the Veyonda® program now well-advanced, the Company is accelerating and expanding its drug discovery efforts in its goal to evolve into a biopharmaceutical company with a robust pipeline of anti-cancer drug candidates developed in-house and fully owned by the Company. Several leads have been identified, all with the objective of leveraging the science and know-how that led to the discovery of Veyonda® to bring more medicines to the growing number of people living with cancer.

BoardThe Board saw a number of changes around the end of the June quarter, reflecting preparation for the Company’s anticipated growth over the next 12 months.

The first change was the appointment of CEO and Founder, Dr Graham Kelly, to Chairman, with the appointment of Dr Greg van Wyk as CEO. The purpose of this was to free up Dr Kelly to oversee the proposed dual listing of Noxopharm on a U.S. securities exchange and to deliver the independence of Nyrada Inc from the parent company whilst leveraging Dr van Wyk’s strategic and operational expertise to lead the Company into the next stage of its lifecycle – one in which the company will take Veyonda® into late stage clinical testing while seeking to grow into a leader in the development of small molecule oncology drugs.

The second change was the resignation of Non-Executive Director, Mr John Moore, in order for him to take up the position of Chairman of Nyrada Inc, thereby creating the third change which was the appointment of Dr Beata Niechoda MD, PhD, MBA as a replacement for Mr Moore. Dr Niechoda had been appointed Special Advisor to the Board earlier this year, providing the Board with an expert and independent view of the Company’s clinical and commercial strategies. The Board is pleased now to have on a formal basis the considerable international pharmaceutical industry experience of Dr Niechoda.

Funding The Company remains aware of its cash position and constantly strives to balance financial security with the cost (and attendant dilutionary effect) of capital raised on-market. The Company last raised capital some 15 months ago (April 2018), which together with the Australian Government’s R&D Rebate Scheme and prudent spending, has allowed it to run and even grow its business over that period.

The latter half of 2018 proved to be a challenging time for raising capital in the biotech sector, a situation which according to the Company’s advisors has only started to improve in recent months, leading the Company to look to raise new capital in June/July. With an eye on a proposed dual listing of Noxopharm on a U.S. securities exchange, the Company believed that it was appropriate to seek to raise that new capital in the U.S. as a necessary introduction of the Company to the U.S. capital markets.

The Company has worked with U.S. and UK investment bank, Laidlaw and Company, on capital raising strategies, reviewing a range of options offered to the Company towards the end of the Financial Year.  As the market was informed, the Company entered into a funding package that it believed best suited its strategy of using a form of short-term financing that provided the flexibility of utilizing funds when  required. Importantly, this will allow the Company to take advantage of any positive market responses to the anticipated news flow up to the time of the proposed U.S. listing and IPO, following which this financing will no longer be used.

The facility provides an immediate injection of AU$4 million, plus the ability to place up to AU$2 million worth of ordinary shares each month for a further 12 months, should this be required. While the facility has a nominal maximum AU$26 million value, (and which could increase with agreement of all parties) the Company does not anticipate utilising anywhere near this amount. The Company intends to work closely with the two U.S. funds who provided this facility to seek to capitalise on what the Company believes will be an upcoming period of strong news flow.

The Company also is anticipating reimbursement of a minimum of $3M in Q3, 2019 through the Federal Government’s R&D Rebate scheme.

Nyrada IncThis last quarter saw important progress in this Company’s development.

A number of steps were taken in preparation for its independence from parent, Noxopharm. Starting with the expansion of the Board from Mr Peter Marks and Dr Graham Kelly, to Mr John Moore (Independent Director and Executive Chairman), Mr Marcus Frampton (Independent and Non-Executive Director) and Dr Rüdiger Weseloh (Independent and Non-Executive Director). Preparation of a Prospectus also has been undertaken in readiness for a proposed listing on ASX in the second half of this year.

There was important progress across the three main R&D programs, with significant progress made in the identification of a lead candidate in the Company’s two main programs – the PCSK9 inhibitor program and the neuroprotectant program. The Company remains strongly of the view that it has identified two potentially major new therapeutics and shortly will be in a position to take both drug candidates on their journey into the clinic.
