Richard Goodfellow, Joint CEO of Scancell, said:
“We are delighted with the results and progress generated from both our ImmunoBody® and Moditope® platform technologies during the period. In particular, the immune response data released today from our lead programme, the SCIB1 ImmunoBody® vaccine for advanced melanoma, has exceeded our highest expectations. We anticipate reporting data from the high dose 8mg arm of this Phase 1/2 trial by 2014 calendar year end. While treated patient numbers are small, we believe our results to date add to the growing body of evidence that suggests that training T cells to target and control tumour growth could be one of the most promising new ways of treating cancer. With that in mind, the discovery of the Moditope® platform technology could add a new dimension to cancer immunotherapy and form the basis of a completely new class of immuno-oncology treatments. We are actively planning the preclinical and clinical development for Modi-1, our lead vaccine arising from this platform, as an immunotherapeutic provisionally for the treatment of triple-negative breast cancer, ovarian and endometrial cancers.
“As previously indicated at the time of our investor update in October, in view of the short to medium term licensing and partnership potential that both the Moditope® and ImmunoBody® programmes now bring to the Company, our strategy requires a more flexible approach. Whilst we are still fully focused on securing a sale of the business at the earliest opportunity, we will also consider technology validating and revenue generating deals on each platform in order to enhance the value of the Company when it is eventually sold.”

Scancell is developing novel immunotherapies for the treatment of cancer based on its ImmunoBody® and Moditope® technology platforms. Scancell’s first ImmunoBody®, SCIB1 is being developed for the treatment of melanoma and is in Phase 1/2 clinical trials. Preliminary evidence from Part 1 of the study showing that SCIB1 produced an immune response which might be associated with clinical benefit in patients with malignant melanoma was released in December 2012.
Scancell’s ImmunoBody® vaccines target dendritic cells and stimulate both parts of the cellular immune system; the helper cell system where inflammation is stimulated at the tumour site; and the cytotoxic T-lymphocyte or CTL response where immune system cells are primed to recognise and kill specific cells.
Scancell has also identified and patented a series of modified epitopes that stimulate the production of killer CD4 that destroy tumours without toxicity. The Directors believe that the Moditope® platform could play a major role in the development of safe and effective cancer immunotherapies in the future.
I am pleased to report the Company’s interim results for the six month period ended 31st October, 2013. During this period the Group has continued progress with the SCIB1 clinical trials and in August 2013 raised £6.1m (net proceeds) in additional investment through a placing and open offer of shares. These funds will enable the Company to commence work on the pre-clinical development of the first Moditope® immunotherapy product and will provide working capital for the completion of the existing SCIB1 clinical trials as well as enable the Company to recruit the further ten patients for the 8mg cohort of the Phase 1/2 trial.
We have also announced today (see separate release) the extremely encouraging new results from the ongoing Phase 1/2 clinical trial in patients with advanced melanoma. This data from Part 2 of the trial shows that all 14 patients produced a melanoma-specific immune response to treatment and all are still alive. Only three patients have any evidence of disease progression to date. In addition, the four patients from Part 1 of the study who were still alive at the time of the Part 1 report (December 2012) are still alive with a median survival time since treatment commenced of 25 months. Furthermore no serious drug related adverse events have been reported.
Profit and Loss Account
The Group made an overall operating loss for the six month period to 31st October 2013 of £1,306,556 (2012: loss of £989,981).
Overall the loss for the six month period was £1,187,574 (2012: loss £923,020).
The cash at bank at 31 October 2013 was £6,395,927 (30 April 2013: £1,491,320) and net assets amounted to £10,006,318 (30th April, 2013: £5,092,145)
SCIB1 melanoma vaccine
Additional encouraging results from the on-going Phase 1/2 clinical trial with SCIB1 in patients with Stage III/IV melanoma were announced today (see separate announcement).
In Part 1 of the study, 5/6 patients allocated to the 2mg and 4mg dose cohorts and who received at least three doses of SCIB1 produced a melanoma-specific immune response to treatment and 4/6 are still alive. In one of these patients all of the lung metastases showed partial or complete regression during treatment. All four surviving patients from Part 1 are still alive after a further 12 months on study. The median survival time from study entry in these two higher dose groups is now 25 months, although in three of these patients there is evidence of disease progression.
Part 2 of the study was conducted in 14 patients with resected Stage III/IV disease. All 14 patients (100%) produced a melanoma-specific SCIB1-induced T cell response to treatment. Only three patients have experienced progressive disease to date and all patients are still alive. The median survival time since initiating treatment with SCIB1 in Part 2 is currently 15 months and 21 months from diagnosis of metastatic disease. Six of these patients are continuing on extended, long-term treatment with SCIB1.
There have been no serious drug-related adverse events to date.
As a result of the positive results and minimal side effects seen with the 4mg dose, Scancell commenced evaluating an 8mg dose in parallel with Part 2 of the Phase 1/2 study. The higher 8mg dose SCIB1 study has been implemented for two reasons:
Firstly, one of the goals of Part 1 of the Phase 1/2 study was to establish a "maximally tolerated dose" of SCIB1 for use in Part 2. As there were no drug related side effects observed at 4mg, a maximally tolerated dose was not reached and a higher dose could improve the immune response even further.
Secondly, we were pleased to see a significant effect on tumour burden in one late stage patient in the Part 1 study. The Part 2 study, however, is primarily designed to assess immune response in resected Stage III/IV patients and although we will be monitoring the time to disease progression, we will not be able to measure an effect on tumour size. The extended Part 1 study using the 8mg dose is in patients with tumour load and will therefore provide the opportunity to assess whether we can reproduce the valuable data reported from Part 1 in an additional group of patients and at a higher dose. Data from this cohort of patients is expected in by 2014 calendar year end.
Moditope® vaccine technology platform
The Company has developed a new platform technology, Moditope® which has been used to develop the lead product, which will henceforth be described as Modi-1. Planning is underway for the preclinical and clinical development of Modi-1 as an immunotherapeutic, provisionally for the treatment of triple-negative breast cancer, ovarian and endometrial cancers. First in-man clinical studies are scheduled to start in 2016. Moditope® harnesses CD4+ cells to eradicate tumours and represents a new class of immunotherapeutic agents. The platform deploys citrullinated tumour-associated peptide epitopes to overcome self-tolerance and destroy tumour cells, with no requirement for blockade inhibitors (for example CTLA4 antibodies and PD-1 inhibitors). It can potentially be expanded to develop multiple immunotherapeutic agents for different cancers.
The ImmunoBody® platform induces a high avidity CD8+ T cell response to tumour associated antigens. As the Moditope® platform stimulates a potent CD4+ T cell response to modified self-antigens both platforms are complementary relying on a response by different classes of T cell for their therapeutic effect. Thus, in principle, a combination of ImmunoBody® and Moditope® derived therapeutics may be a powerful approach to the treatment of both early and late stage cancers.
A patent for Scancell’s DNA ImmunoBody® technology has been granted in Australia. This is the first jurisdiction to approve the DNA patent and is a key landmark on the road to comprehensively protecting Scancell’s DNA ImmunoBody® platform technology.
The patent, which covers the DNA ImmunoBody® platform technology and is of importance for the protection of Scancell’s entire pipeline of ImmunoBody® vaccines, has also been filed in the US, Europe and other major markets. The composition of matter patent for SCIB1, Scancell’s ImmunoBody® vaccine for the treatment of melanoma, has already been granted in Europe, Turkey and South Africa. Scancell’s protein ImmunoBody® patent has also been approved in the US, Europe, Japan and Australia.
A broad patent for Scancell’s Moditope® has been filed to protect this platform and covers the use of multiple tumour-associated modified epitopes for the treatment of cancer.
Scancell signed an agreement with Ichor in July 2009 which provides for the supply and use of the TriGrid™ device for Scancell’s pre-clinical and clinical studies with SCIB1 and gives Scancell an option (‘The Option’) to license TriGrid™ for commercial use on payment of certain undisclosed milestones and royalties. The Option could be exercised at any time up to July 2014. In return, Ichor was granted share options to subscribe for Scancell shares at a subscription price of 4.5p including an option over 1,592,310 shares upon regulatory approval to start clinical trials being granted in the UK.
Since the end of the period, Scancell has been granted an extension of The Option to commercialise Ichor’s proprietary TriGrid™ electroporation delivery system with SCIB1, Scancell’s ImmunoBody® vaccine for the treatment of melanoma. Under the terms of the extension, Scancell’s Option, which had been due to expire in July 2014, will be extended until July 2016. In exchange, Scancell agreed to waive the two year lock-in period following the exercise of Ichor’s options over 1,592,310 shares at 4.5p which have been subsequently placed on the market.
Share Capital – Placing and Open Offer
On 1st August 2013 the shareholders of the Company approved resolutions for; (i) the placing of 20,000,000 ordinary 0.1p shares at a price of 22.5p and (ii) an open offer to qualifying shareholders, who had not taken part in the placing, to subscribe for 8,888,888 ordinary 0.1p shares at a price of 22.5p. Following the approval of these resolutions the company raised £6.1m, net of costs.
The results released today from Part 2 of the Phase 1/2 study with the SCIB1 vaccine in advanced melanoma support the encouraging results from Part 1 of the study reported last year. Importantly, we have confirmed that SCIB1 induces a consistent melanoma-specific immune response in Stage III/IV melanoma patients, especially in those with resected disease. Whilst the numbers are still small, the results suggest that SCIB1 may be contributing to prolonged survival by controlling tumour growth. We remain confident that, as further long-term data is generated, both in these patients and those treated with the higher 8mg dose, the clinical and commercial potential of Scancell’s ImmunoBody® vaccine approach will be fully apparent. The results from this trial to date have exceeded our highest expectations and support our belief that the highly targeted ImmunoBody® approach is delivering potent T cells that can control malignant disease and adds to the growing body of evidence that suggests that training T cells to target and control tumour growth could be of the most promising new ways of treating cancer. Furthermore, in patients with more extensive metastases, it is feasible that combining SCIB1 with the latest checkpoint inhibitor drugs, which allow T cells to work better within the tumour environment, may offer further patient benefit.
The discovery of the Moditope® platform technology and its ability to induce potent CD4+ T cells against tumour associated epitopes could add a new dimension to cancer immunotherapy and form the basis of a completely new class of immune-oncology treatments.
As previously indicated at the time of our investor update in October, in view of the short to medium term licensing and partnership potential that both the Moditope® and ImmunoBody® programmes now bring to the Company, our strategy requires a more flexible approach. Whilst we are still fully focused on securing a sale of the business at the earliest opportunity, we will also consider technology validating and revenue generating deals on each platform in order to enhance the value of the Company when it is sold.
