Commenting on the Results, Professor Malcolm Young, CEO of e-Therapeutics, said: “This has been another period of significant progress. In the past six months we have advanced our most important product, the cancer drug ETS2101, into two phase I trials. We have also continued to re-shape our drug pipeline, with a clear determination to focus investment into the most promising assets in our discovery and development portfolios. We now look forward to some major clinical milestones and to new outputs from our unique drug discovery platform in network pharmacology.”

Chairman’s statement

Overview

We are pioneers of a new approach to drug discovery based on network pharmacology. Our business revolves around monetising drugs resulting from our discovery programme. Our strategy is to advance the most promising of these through clinical trials to a point where they can be licensed on attractive terms to larger companies. We expect this to provide us with revenues in the form of upfront payments, progress-based milestone payments and royalties on any sales. During the past six months we have taken our most important product candidate, the cancer drug ETS2101, forward into two phase I trials. This is a key step in executing our business plan. We have also continued to build a broadly based business through work to discover more new drugs at our Network Pharmacology Centre near Oxford and by selectively advancing other candidates alongside ETS2101.

Cancer drug enters trials

Our principal objective for 2012 was to move our cancer drug ETS2101 into clinical trials. The phase I trial programme began in June, when investigators at the UC San Diego Moores Cancer Center in La Jolla, California, started enrolling patients with primary or metastatic brain cancer into an investigator-initiated study. Up to 24 patients will be included in the trial, which has a dose-escalating design intended to establish a dose for phase II development, assess safety and tolerability and identify any initial signs of anti-cancer activity. In September, we started a second phase I trial at two hospitals in the UK. This will enrol around 45 patients with a variety of solid tumours. The aims and design of the UK trial are similar to those of the brain cancer study. First findings from the phase I programme are anticipated late this year, with further data from both trials available during 2013. We expect final results from the brain cancer study in Q4 2013 and from the solid tumour study in Q1 2014.

ETS2101 represents a significant commercial opportunity because of its potential to address unmet needs in multiple high-value oncology market segments. An early focus on brain cancers reflects particularly encouraging preclinical data from brain cancer cell lines and evidence that the drug crosses the blood-brain barrier, which compromises the effectiveness of many other cancer drugs in this setting. However, positive findings from other cancer lines suggest the drug could have wider potential. Our broad phase I programme is the first step in evaluating which cancer patients might be most likely to benefit from the product.

Decisions and progress on other candidates

Our second priority in the clinic is to complete a phase IIb trial of ETS6103 in patients with major depressive disorder. We have experienced a delay in the programme because it took longer than we anticipated to produce tablets that release the drug over an optimal time period. We now expect to complete a submission to the UK regulator by the end of this year and to start dosing patients in Q2 2013. Our phase IIb trial will build on an earlier, small phase IIa study that produced encouraging results with ETS6103 in comparison with the approved tricyclic anti-depressant amitriptyline. The forthcoming trial will compare two doses of ETS6103 with amitriptyline in a randomised protocol including around 120 patients who have failed prior treatment with an SSRI anti-depressant. Results are expected in Q2 2014. We regard ETS6103 as a more modest commercial opportunity than ETS2101 but one that clearly justifies the limited further investment needed to complete a proof-of-concept trial designed to demonstrate the product’s value to potential partners.

We have two preclinical programmes targeting infectious diseases. One of these, ETX1153a, was designed as a topical treatment for MRSA. Final preclinical tests have reinforced the case that this drug kills a wide range of MRSA strains at low concentrations and has a good resistance profile, as predicted by our network pharmacology platform and shown in earlier testing. However, re-evaluation of development considerations and the commercial opportunity for the drug has led us to decide that there are better uses of our resources than pursuing this programme, and it will therefore be discontinued. Our second anti-infective, ETX1153c, designed for treatment of C. difficile infection, remains of significant interest. We announced in May that additional preclinical work was needed to surmount practical issues in formulating the drug’s two active ingredients in a single tablet. These ingredients have a synergistic (more than additive) effect against C. difficile when used in combination. Our preclinical work is ongoing and we expect to make a decision on whether to advance a candidate into the clinic in mid-2013.

Discovery – fuelling future growth

At our Network Pharmacology Centre near Oxford, which was opened in February by UK Prime Minister David Cameron, our scientists are generating a pool of new drug candidates. We will select the most attractive of these, based on technical, clinical and commercial criteria, to advance into the clinic. Our effort is concentrated on complex diseases in which we believe our technology has particular strengths, principally cancer and nervous system disorders, although we also have an important research strand in pain. We remain on track to advance at least one new candidate from discovery into development by the end of 2013. In addition, we continue to explore opportunities for discovery collaborations with other companies. Our leading position in network pharmacology-based drug discovery gained further support in August through the grant of another European patent.

Strong balance sheet supports investment

Our investment in discovery and development is reflected in an increase in our first-half net loss to £1.8 million from £1.5 million during the equivalent period last year. There were no revenues to offset our operating expenses (H1 2012: nil). The income statement shows tax receivable of £0.3 million for the first half, reflecting our expected receipt of R&D tax credits associated with qualifying R&D expenditure.

We maintain a strong balance sheet that supports our investment in R&D. At 31 July 2012 we had cash and short-term investments of £11.7 million, compared with £15.3 million at 31 July 2011 and £13.9 million at 31 January 2012.

The Company’s strategy is to license its products to pharmaceutical companies for late-stage development and commercialisation. The Company may also enter discovery collaborations with selected partners. We anticipate continuing losses until revenues from these sources exceed investment in R&D. Based on our latest projections, we expect our current funds to support our planned investment in discovery and development through mid-2014 even in the absence of any income from partners.

Board enhanced by new appointment

In February we appointed Dr Rajesh Chopra, a senior executive at Celgene Corporation, as a Non-Executive Director. Raj has brought a wealth of relevant R&D and clinical experience to our Board.

Outlook

We are now close to reporting our first clinical data since our refinancing in 2011. Initial findings from the cancer programme with ETS2101 will be followed next year by more extensive data, with final results from the brain cancer study expected in late 2013 and final results from the solid tumour study expected in Q1 2014, followed soon afterwards by data from the phase IIb trial of our antidepressant, ETS6103. Advancing these two drugs rapidly towards potential partnering deals is our key priority, but we are also very enthusiastic about applying our unique discovery platform to generate further new candidates that will fuel long-term growth.
