About Scancell

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 being evaluated in a Phase 1/2 clinical trial. Data from the trial demonstrate that SCIB1, when used as monotherapy, has a marked effect on tumour load, produces a melanoma-specific immune response and highly encouraging survival trend without serious side effects.

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 Tlymphocyte or CTL response where immune system cells are primed to recognise and kill specific cells. 

Pre-clinical data on a combination of SCIB1 and checkpoint inhibition (blockade of the PD-1 immune checkpoint pathway) has shown enhanced tumour destruction and significantly longer survival times than
when either treatment was used alone.

Scancell has also identified and patented a series of modified epitopes that stimulate the production of killer CD4+ T cells 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.

CHAIRMAN’S STATEMENT

I am pleased to report the Company’s interim results for the period ended 31 October 2015. During the period the Company has continued to make good progress across all fronts.

  • The latest survival and safety data from the Phase 1/2 clinical trial continues to suggest that SCIB1has the potential to become both the first stand-alone adjuvant treatment for early stage metastatic melanoma and an attractive partner with checkpoint inhibitors for later stage disease.
  • Results from a pilot study with ImmunID illustrate ImmunTraCkeR®’s potential to be used as a companion diagnostic to predict early clinical response to SCIB1, both during further clinical trials and during subsequent routine clinical use.
  • Scancell is to work with leading US melanoma specialists to conduct a Phase 2 checkpoint inhibitor combination study with SCIB1. This pivotal initiative which aims to demonstrate an increase in the response rates to checkpoint inhibitor therapy without additional toxicity is expected to commence in early 2017.
  • The Company’s second immunotherapy platform received a significant boost following the publication of a paper in Cancer Research underpinning the scientific basis for the Moditope® platform.
  • Progress has been made in the pre-clinical development of Modi-1, the lead pipeline candidate from the Moditope® platform significantly increasing the number of patients with triple negative breast and ovarian cancer eligible for treatment.

Financial

Profit and Loss Account

The Group made an overall operating loss for the six month period to 31 October 2015 of £1.37 million (2014: loss of £1.56 million). The reduced loss reflects a fall in research and development expenditure in the period as the SCIB1 clinical trial reaches completion and includes a reduction in administrative expenditure.

Overall the loss for the six month period was £1.17 million (2014: loss £1.34).

Balance Sheet

The cash at bank at 31 October 2015 was £1,813,718 (30 April 2015: £3,059,001) and net assets amounted to £5,606,941 (30 April 2015: £6,754,002).


ImmunoBody® platform

Scancell’s ImmunoBody® immunotherapy platform uses the body’s immune system to identify, attack and destroy tumours. This is achieved by enhancing the uptake and presentation of cancer antigens to harness
high avidity T cell responses. Each ImmunoBody® vaccine can be designed to target a particular cancer in a highly specific manner, offering the potential for enhanced efficacy and safety compared with more
conventional approaches. The platform has been validated both in animals and in the clinic with the Company’s first cancer vaccine, SCIB1, and many opportunities also exist for the development of a pipeline of ImmunoBody® vaccines, both for cancer and chronic infectious diseases.

SCIB1 melanoma vaccine
In July this year the Company announced that it has closed patient recruitment for its SCIB1 ImmunoBody® Phase 1/2 clinical trial in patients with Stage III/IV melanoma.

The Phase 1/2 clinical trial, conducted across six UK centres, is an open label, non-randomised study to determine the safety and tolerability of SCIB1 administered intramuscularly using an electroporation device (TriGrid Delivery System, manufactured by Ichor Medical Systems, USA). Part 1 was a dose-escalation to determine the dose for Part 2. While the primary objective of the study was to assess safety and tolerability, the study is also assessing immune response, anti-tumour activity and the ability of SCIB1 to delay or prevent disease recurrence in patients with resected disease.

In line with previously reported results, SCIB1 continues to be a safe and well tolerated treatment with no withdrawals from the study due to drug-related adverse events. All 20 patients with resected disease remain alive. The median observation time in the 16 patients with resected disease who received 2-4 mg doses of SCIB1 is now 42 months since study entry and 11 are still disease free. The median observation time for the resected patients on the 8mg dose who were recruited to the study later is 10 months and all are still disease free to date. Patients on long-term continuation treatment will continue to be dosed for up to five years from the end of the main study period. Nine patients are currently on long-term treatment (up to 11 treatments given) and all remain disease free for periods of up to 39 months from the start of treatment.

The main study closed on 29 October 2015. The Company is in the process of analysing the data and preparing a final clinical study report which is expected to be completed during the first half of 2016.

The enhanced survival and safety in our SCIB1 study combined with the novel mechanism of action which delivers high T cell avidity, has re-ignited the interest of pharmaceutical companies, especially in combination with checkpoint inhibitors.

SCIB2 vaccine
Our second ImmunoBody® vaccine, SCIB2 has been designed to be effective in over 90% of patients that over express the cancer antigen NY-ESO-1, including those with lung and other epithelial cancers.

US Clinical Study
The Company has announced the formation of a core US investigator team to lead a checkpoint inhibitor combination study with Scancell’s lead cancer vaccine, SCIB1. The team will be led by Principal Investigator Dr Keith Flaherty, Director of the Termeer Center for Targeted Therapy at Massachusetts General Hospital and Associate Professor at Harvard Medical School and will be supported, amongst others yet to be announced, by:

  • Dr Paul Chapman (Memorial Sloan Kettering)
  • Dr Jennifer Wargo and Dr Michael Davies (MD Anderson)
  • Dr Rene Gonzalez (University of Colorado)

The clinical study will assess the impact of adding SCIB1 to checkpoint inhibitors in patients with late stage melanoma. The aim will be to improve the objective response rates of anti-PD-1 (“checkpoint inhibitor”) monotherapy without adding additional toxicity. It is expected that the study will enrol approximately 80 Stage III/IV metastatic melanoma patients and commence in early 2017, with completion approximately 18 months later. We are delighted to have secured the help and support of such a prestigious group of US specialists to undertake this important study.

ImmunID Collaboration
The Company is continuing to work with ImmunID on a research project aimed at predicting which patients will respond best to SCIB1 treatment. This collaboration is providing further insight into T cell diversity in patients treated with our SCIB1 vaccine and their response to the treatment over time. Results from the first pilot study with ImmunTraCkeR® have indicated its potential to be used as a companion diagnostic to predict early clinical response to SCIB1 both during further clinical trials with SCIB1 and during routine clinical use; further studies are planned.

Moditope® platform

Modi-1
Scancell’s Moditope® immunotherapy platform is based on exploiting the normal immune response to stressed cells, which is largely mediated by CD4+ T cells, and harnessing this mechanism to eradicate cancer cells. Scancell’s first target for Moditope® is vimentin – a major cytoskeletal protein found in mesenchymal cells. Many epithelial tumours switch from expression of cytokeratin to vimentin during metastasis in a process known as epithelial mesenchymal transition (EMT); this change in phenotype enables the cell to become mobile and metastasize to new locations in the body.

The pre-clinical development of Modi-1, the lead candidate from our Moditiope® platform technology is continuing to progress and the peptide components have now been modified to include an additional enolase peptide. This improvement has meant that the product is expected to be effective in up to 95% of patients with triple negative breast and ovarian cancers. The Company expects to start clinical trials with Modi-1 in 2017.

The Company was also delighted to announce in January the publication of a paper in Cancer Research underpinning the scientific basis for the Moditope® platform. Cancer Research is one of the most highly regarded and widely read cancer journals and publication in this prestigious journal is a tribute to Scancell’s scientific team under the leadership of Prof Lindy Durrant.

Board

Scancell has strengthened its commercial and clinical development expertise with the appointment of Dr Peter Brown as an advisor to the Company and myself to the Board, initially as a senior Non-Executive Director and now as Chairman. David Evans has stepped down as Chairman and the Board would like to thank him for his exemplary leadership and sage advice during his tenure.

Peter is a highly experienced pre-clinical and clinical development consultant to the pharmaceutical industry and his expertise in designing and managing international late stage oncology clinical trials in both small and large pharmaceutical companies will be of enormous help as the Company continues to grow.

Outlook
The latest data on SCIB1, both in terms of the unprecedented survival of Stage III/IV melanoma patients with resected disease, combined with anti-tumour responses in late stage patients and compelling animal data showing the potential value of a SCIB1/checkpoint inhibitor combination, has set the stage for an expanded clinical trial programme with a prestigious group of US specialists.

Progress has also continued to be made with the Moditope® platform and it is anticipated that the first product, Modi-1, will be moving into the clinic in 2017. Publication of the scientific data supporting the Moditope® platform in Cancer Research is also a key milestone and a tribute to the strength of the Company’s research team.

These developments have reignited interest in the Company from all of its stakeholders, including the pharmaceutical industry and potential new investors, especially in the US.

The Board believes that investment in further focused clinical studies on both SCIB1 and Moditope® could add significant value to the Company and is exploring with its advisers a number of funding options to ensure
that the Company has the resources to progress these programmes further.

As part of this process, the Board and management will be further strengthened to prepare the Company for its future as a later stage development company.

I have become Chairman as the Company is poised for an exciting future and I am committed to strengthening our presence in the US and to building the Company into one of the leaders in immunooncology.

Key Moditope® paper published in Cancer Research

Moditope® citrullinated peptides stimulate potent anti-tumour responses

Scancell Holdings Plc, (AIM:SCLP), today announced the publication, on line, of a full paper in Cancer Research describing the rationale behind the Company’s Moditope® platform and the experimental results that support it.1 Cancer Research is the official journal of the American Association for Cancer Research and is one of the world’s foremost peer-reviewed journals in the field of oncology.

Prof Lindy Durrant, Joint CEO of Scancell, said: “The publication of this paper on the science behind Moditope® in such a prestigious and widely read cancer journal is not only a great achievement for the research team at Scancell, it provides a ringing endorsement from the scientific community for this completely innovative approach to the treatment of cancer. This important paper lays out the foundation, rationale and experimental basis for the Moditope® platform and its potential to generate effective cancer vaccines.”

The lead product from the Moditope® platform, Modi-1, is progressing through pre-clinical development with first in man studies targeted in triple negative breast cancer and ovarian cancer patients.

Abstract

Citrullinated vimentin presented on MHC-II in tumor cells is a target for CD4+ T cell-mediated antitumor immunity

“Stressful conditions in the harsh tumor microenvironment induce autophagy in cancer cells as a mechanism to promote their survival. However, autophagy also causes post-translational modification of proteins which are recognized by the immune system. In particular, modified self-antigens can trigger CD4+ T cell responses that might be exploited to boost antitumor immune defenses. In this study, we investigated the ability of CD4 cells to target tumor-specific self-antigens modified by citrullination, which converts arginine residues in proteins to citrulline. Focusing on the intermediate filament protein vimentin, which is frequently citrullinated in cells during epithelial-to-mesenchymal transition of metastasizing epithelial tumors, we generated citrullinated vimentin peptides for immunization experiments in mice. Immunization with these peptides induced IFNγ- and granzyme B-secreting CD4 T cells in response to autophagic tumor targets. Remarkably, a single immunization with modified peptide, up to 14 days after tumor implant, resulted in long term survival in 60-90% of animals with no associated toxicity. This antitumor response was dependent on CD4 cells and not CD8+ T cells. These results show how CD4 cells can mediate potent antitumor responses against modified self-epitopes presented on tumor cells, and they illustrate for the first time how the citrullinated peptides may offer especially attractive vaccine targets for cancer therapy.”

About Scancell

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 being evaluated in a Phase 1/2 clinical trial. Data from the trial demonstrate that SCIB1, when used as monotherapy, has a marked effect on tumour load, produces a melanoma-specific immune response and highly encouraging survival trend without serious side effects. In patients with resected disease there is increasing evidence to suggest that SCIB1 may delay or prevent disease recurrence.

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 Tlymphocyte or CTL response where immune system cells are primed to recognise and kill specific cells.

Pre-clinical data on a combination of SCIB1 or SCIB2 and checkpoint inhibition (blockade of the PD-1 or CTLA-4 immune checkpoint pathways) have shown enhanced tumour destruction and significantly longer survival times than when either treatment was used alone.

Scancell has also identified and patented a series of modified epitopes that stimulate the production of killer CD4+ T cells 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.

Translating innovative science into ground-breaking new products

Scancell Holdings Plc, (AIM:SCLP), the developer of novel immunotherapies for the treatment of cancer, will today provide a business and R&D update following the Company’s AGM. Dr Richard Goodfellow and Prof Lindy Durrant, Scancell’s joint CEOs, will present a summary of the latest available data from the SCIB1 Phase 1/2 clinical trial in malignant melanoma, the lead programme from the Company’s ImmunoBody® platform. The Company will also provide an update on the latest data and plans for the Moditope® platform.

Highlights

  • Maturing survival and safety data from Phase 1/2 clinical trial continues to suggest that SCIB1 has the potential to become the first effective stand-alone adjuvant treatment for early stage metastatic melanoma, a billion US dollar market opportunity
    • All 20 patients with resected tumours at study entry remain alive
      • Of the 16 patients who received 2-4mg doses of SCIB1
        • Median survival since entry is 39 months or 44 months since first diagnosis of metastatic disease
        • Only five patients have progressed
      • Of the four patients who received an 8mg dose (recruited after lower dose cohorts)
        • None have progressed
        • Median survival since entry is 7 months to date
    • Final Clinical Study Report for trial expected H1 2016
  • Further animal data has confirmed that SCIB1 offers the potential to be combined with checkpoint inhibition thereby increasing response rates beyond the 25-30% of patients responding to checkpoint inhibitors alone
  • Progress in pre-clinical development of Modi-1, lead pipeline candidate from Moditope® platform
    • Modi-1 peptide components broadened to include additional enolase peptide
      • Significantly extends tumour coverage and patient eligibility in triple negative breast and ovarian cancer patient populations
      • First in Man studies in these settings provisionally targeted for Q4 2016
  • Roadmap for further clinical development of Immunobody® and Moditope® assets outlined
  • Continuing to explore various options for the Company consistent with maximising shareholder value

Prof Lindy Durrant, Joint CEO of Scancell, said: “We continue to be excited by the compelling data emerging from our Phase 1/2 clinical trial in metastatic melanoma with SCIB1, the lead pipeline candidate from our ImmunoBody® platform. In particular the encouraging survival data in patients with resected disease continues to support its potential to become the first effective, stand-alone adjuvant treatment for early stage metastatic melanoma. We have also continued to progress the pre-clinical development of Modi-1, the lead candidate from our second platform technology, Moditope®. The product has been further improved to be potentially effective in up to 95% of patients with triple negative breast and ovarian cancers. We look forward to progressing Modi-1 into the clinic in these indications towards the end of 2016.”

Dr Richard Goodfellow, Joint CEO of Scancell, added: “The commercial launch of the first cancer immunotherapies has cemented the importance of this approach in the treatment of cancer. We continue to believe that Scancell has a complementary and potentially valuable pipeline of immuno-oncology assets that is underpinned by two differentiated technology platforms.

“We look forward to communicating the findings from the final Clinical Study Report from our SCIB1 Phase 1/2 trial during the first half of 2016 and to progressing Modi-1 into the clinic towards the end of that year. While we continue to refine our roadmap for the future development of assets from both our platforms, we also continue to explore various options for the Company that are consistent with maximising shareholder value.”

David Evans, Non-Executive Chairman of Scancell, commented: “Given the strength of the clinical data and product pipeline, the Board believes that investment in further focused clinical studies on both SCIB1 and Moditope® could add significant value to the Company and is actively evaluating the possibility of conducting one or more of these studies on its own behalf alongside other strategic opportunities for realising shareholder value. The Company is poised for an exciting future as one of the leaders in immuno-oncology and we anticipate strengthening both the Board and management as the Company evolves into a later stage development business.”

About Scancell

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 being evaluated in a Phase 1/2 clinical trial. Data from the trial demonstrate that SCIB1, when used as monotherapy, has a marked effect on tumour load, produces a melanoma-specific immune response and highly encouraging survival trend without serious side effects. In patients with resected disease there is increasing evidence to suggest that SCIB1 may delay or prevent disease recurrence.

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.

Pre-clinical data on a combination of SCIB1 or SCIB2 and checkpoint inhibition (blockade of the PD-1 or CTLA-4 immune checkpoint pathways) have shown enhanced tumour destruction and significantly longer survival times than when either treatment was used alone.

Scancell has also identified and patented a series of modified epitopes that stimulate the production of killer CD4+ T cells 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.

PIVAC Conference Presentations

Six scientific presentations at the Progress in Vaccination against Cancer Conference highlight potential of ImmunoBody® and Moditope® platform technologies

Scancell Holdings plc (‘Scancell’ or the ‘Company’), the developer of novel immunotherapies for the treatment of cancer, today announces that six scientific presentations on the Company’s ImmunoBody® and Moditope® immunotherapy platforms will be delivered at the 15th International Conference on Progress in Vaccination against Cancer (PIVAC-15), 6-8 October 2015. The presentations exemplify the growing body of data that are emerging from these platform technologies that suggest that they could be potentially important approaches to delivering effective and complementary immunotherapies to treat a range of cancers.

The six presentations are as follows:

  • “Citrullinated vimentin, which is presented on MHC-II on tumour cells, is a novel rejection target for CD4 T cells”1 (Moditope®)
  •  “A clinical trial of a DNA vaccine (SCIB1) that targets dendritic cells in vivo in fully resected melanoma patients; a vaccine to prevent disease recurrence?”2 (SCIB1 ImmunoBody®)
  •  “SCIB1 DNA vaccination synergises with PD-1 blockade to induce efficient tumour therapy of poorly immunogenic tumours”3 (SCIB1 ImmunoBody®)
  •  “SCIB2 targets NY-ESO-1 epitopes to induce potent anti-tumour immunity which is enhanced by Treg depletion or checkpoint blockade”4 (SCIB2 ImmunoBody®)
  •  “Adjuvant choice modulates self antigen specific CD4 responses generated by peptide vaccination”5 (Moditope®)
  •  “Anti-tumour immune responses to citrullinated enolase”6 (Moditope®)

Prof Lindy Durrant, Joint CEO of Scancell and Professor of Cancer Immunotherapy at Nottingham University, commented: “Scancell’s presentations at this important conference exemplify the growing body of exciting data emerging from both our SCIB1 clinical trial and our ImmunoBody®, and Moditope®, immunotherapy technology platforms, and provide a solid foundation for building a broad immuno-oncology franchise in the future.”

Final Results for the year ended 30th April 2015

Survival data for lead vaccine SCIB1 strengthens; new data demonstrates potential benefits of combining ImmunoBody® vaccines with checkpoint inhibition

Scancell Holdings plc, (‘Scancell’ or the ‘Company’) the developer of novel immunotherapies for the treatment of cancer, announces results for the year ended 30 April 2015.

Highlights during the period:

  • Positive data showing highly encouraging survival times from the on-going Phase 1/2 clinical trial in patients with Stage III/IV melanoma treated with the SCIB1 ImmunoBody
  • Adjuvant melanoma* represents a significant new market opportunity for SCIB1
    • All 20 resected patients in the Phase 1/2 clinical trial are still alive
    • SCIB1 may offer protection from recurrence of melanoma without serious side effects
  • Data supporting the rationale for combining Scancell's ImmunoBody® vaccines with checkpoint inhibitors has continued to strengthen
  • Pre-clinical data demonstrates that combining SCIB1 and SCIB2 with checkpoint inhibition (PD-1 and CTLA-4 blockade), produced enhanced tumour destruction and longer survival times than when either treatment was used alone
  • SCIB2 is ready for further pre-clinical development as a potential immunotherapy for tumours expressing the NY-ESO-1 antigen
  • Scancell received US patent for its DNA ImmunoBody® platform technology, following grant of counterparts in Australia, China and Japan
  • Modi-1, Scancell’s lead vaccine from Moditope® platform, is on schedule to start clinical trials in Q4 2016
  • Two new Moditope® protein targets have been identified
  • Loss for the year of £2,414,630 (2014: loss £2,222,954) as a result of expected additional expenditure on the SCIB1 clinical trials and the further development of Moditope®
  • Group cash balance at 30 April 2015 was £3,059,001 (30 April 2014: £5,566,234)

*Patients without measurable disease following surgery but where there remains a high risk of relapse

Dr. Richard Goodfellow, Joint CEO of Scancell, said: “We continue to make significant progress with both of our platform technologies and pipeline. We remain excited with the data arising from our SCIB1 Phase 1/2 clinical trial in patients with Stage III/IV melanoma. In particular, the increased survival times and low incidence of adverse events in those patients with resected tumour demonstrates that SCIB1 has the potential to be an effective new treatment option in patients with adjuvant melanoma. With recruitment now closed we expect to report headline results from this open label trial around the end of this year. Additionally, evidence is emerging that our ImmunoBody® vaccines may also be effectively deployed as part of a combination therapy to treat late stage melanoma patients. Our second platform technology, Moditope®, has also yielded its first development candidate, Modi-1, which is on track to start clinical trials in 2016 and two further Moditope® protein targets have been identified.

“We remain confident in the prospects for the Company and its differentiated pipeline of cancer immunotherapies as we continue to evaluate all potential opportunities for increasing shareholder value.”

AGM research and development update highlights progress in both SCIB1 clinical trial and Moditope®

Scancell Holdings Plc

AGM research and development update highlights progress in both SCIB1 clinical trial and Moditope® platform

 Scancell Holdings Plc, (AIM:SCLP), the developer of novel immunotherapies for the treatment of cancer, will today provide a research and development update following the Company’s AGM. Dr Richard Goodfellow and Prof Lindy Durrant, Scancell’s joint CEOs, will present an update on progress with the new Moditope® platform as well as the ongoing SCIB1 Phase 1/2 clinical trial in malignant melanoma, the lead programme from the Company’s ImmunoBodyplatform.

Highlights

  • Encouraging survival and safety data from Phase 1/2 clinical trial suggests that SCIB1 has the potential to become the first effective stand-alone treatment for adjuvant melanoma. All 16 patients with fully resected disease are still alive with a median survival of 26 months after starting treatment and only four have shown disease progression
  • Adjuvant melanoma represents a significant new market opportunity for SCIB1.
  • Combining SCIB1 and PD-1 blockade in animals enhances tumour destruction and extends survival times supporting the use of the combination for later stage disease
  • Modi-1 on schedule to be ready for clinical trials in 2016
  • Two new Moditope® protein targets identified

Dr Lindy Durrant, Joint CEO of Scancell, comments: “Modi-1 remains on track for start of first-in man clinical trials in 2016. The identification of new targets suggests that Moditope has significant potential as a platform for generating multiple cancer immunotherapeutics. In addition to the reported positive data from SCIB1, our Immunobody® platform continues to make good progress with a second vaccine target for lung cancer and the potential to take the platform into chronic infectious diseases.”

Dr Richard Goodfellow, Joint CEO of Scancell, adds: “Cancer immunotherapy is emerging as one of the most exciting areas of pharmaceutical research and development. Scancell now has two innovative technology platforms in this emerging field, both of which are currently being evaluated by a number of pharmaceutical companies under a CDA. The encouraging survival data on SCIB1, especially in patients with resected disease, offers an even greater market opportunity for SCIB1 and our pipeline of ImmunoBody® vaccines than was originally envisaged.”

Research and Development Update

SCIB1

We are pleased to announce further encouraging data from the on-going Phase 1/2 clinical trial in patients with Stage III/IV melanoma treated with SCIB1. To date, 32 patients have been treated with SCIB1, including seven at the higher 8mg dose. Six patients are currently on long-term treatment and have received between 4 and 6 further doses of SCIB1 every 3-6 months. Although recruitment of patients with advanced disease remains challenging it is expected that enrolment for the study will be completed during 2Q15. A new clinical centre has been established at the Royal Surrey County Hospital in Guildford to accelerate recruitment. SCIB1 continues to be a safe and well tolerated treatment with no withdrawals from the study due to adverse events.

Overall, only five of the 27 patients who have received at least three doses of 2-8mg SCIB1 since commencement of the study in 2010 have died. Median survival time in Part 1 patients who received at least three treatments with the 2mg/4mg doses of SCIB1 is now 34 months since study entry. This group of patients had 1-year, 2-year and 3-year survival rates of 100%, 67% and 50%, respectively. For the Part 1 8mg cohort of patients, who were recruited later, the median survival time is currently 13 months since study entry. The median survival time since initiating treatment with SCIB1 in Part 2 patients with resected disease (and receiving 4mg doses of SCIB1) is currently 25 months.

Importantly, all 16 patients (two in Part 1 and 14 in Part 2) with fully-resected metastatic disease (nine Stage III and seven Stage IV) are still alive with a median survival time of 26 months since study entry (range 20-39 months) and only four have shown evidence of disease progression. The Stage III patients have a median survival time of 26 months since study entry and two (22%) have progressed. This compares extremely favourably with results from a peptide vaccine trial (Slingluff et al., 2011) where 52% of fully-resected Stage III patients had progressed and 33% had died two years after the start of treatment. The Stage IV patients treated with SCIB1 have a median survival time of 24 months since study entry and two of these patients (22%) have also progressed. In the Slingluff study, 50% of the fully-resected Stage IV patients had progressed and 19% had died after two years of treatment.

These results in patients with resected disease suggest that SCIB1 may have an important role to play as first line treatment in adjuvant melanoma. These are patients who no longer have measurable disease (following surgery) and are often generally quite well. However, they are at a high risk of recurrence and currently have very few, if any, effective treatment options. This represents a significant and as yet untapped market opportunity, including some 360,000 patients in the US alone, of whom around 45% have the MHC antigen HLA-A2 and are therefore suitable for SCIB1 treatment.

Animal data supporting the synergistic effect of combining SCIB1 with PD-1 blockade was announced in August. Any patients that progress following SCIB1 monotherapy, or indeed any patient with more advanced disease, may therefore benefit from the combination of SCIB1 with a checkpoint inhibitor.

ImmunoBody® platform

Scancell’s Immunobody® immunotherapy platform enhances the uptake and presentation of cancer antigens to harness the high avidity T cell responses that destroy tumours. The platform has been validated both in animals and in the clinic with SCIB1 but many opportunities also exist for the development of a pipeline of ImmunoBody® vaccines, both for cancer and chronic infectious diseases.

A second ImmunoBody® vaccine targeting the lung cancer antigen NY-ESO-1 (SCIB2) has been developed to the point at which the product is fully defined and ready for further preclinical development as a potential immunotherapy for any tumour that expresses the NY-ESO-1 antigen such as lung, oesophageal, gastric, ovarian and bladder cancers. During the past 12 months research on other ImmunoBody® vaccines for prostate, liver and colorectal cancer have also been further advanced.

In addition, Scancell has conducted proof of concept studies with ImmunoBody® constructs expressing antigens from influenza and Epstein Barr virus and is in early discussions with potential partners for the co-development of ImmunoBody® vaccines for the treatment or prophylaxis of infectious diseases.

Modi-1

Scancell’s Moditope® immunotherapy platform is based on exploiting the normal immune response to stressed cells, which is largely mediated by CD4+ T cells, and harnessing this mechanism to eradicate cancer cells. Scancell’s first target for Moditope® is vimentin – a major cytoskeletal protein found in mesenchymal cells. Many epithelial tumours switch from expression of cytokeratin to vimentin during metastasis in a process known as epithelial mesenchymal transition (EMT); this change in phenotype enables the cell to become mobile and metastasize to new locations in the body.

Scancell has now selected two modified vimentin peptides in which the arginine residues have been substituted by citrulline to form the basis of its first Moditope® development candidate, Modi-1. The inclusion of additional modified peptides from other Moditope® target proteins into Modi-1 is currently under review. Animal studies have shown that the two vimentin peptides stimulate potent anti-tumour responses and leads to significant improvements in survival, suggesting that the Modi-1 product could have outstanding potential as a novel immunotherapy. Immune response studies with cells isolated from cancer patients have confirmed that T cell responses were stimulated by both modified vimentin peptides.

Optimisation studies have identified the adjuvant, dose and administration route for testing Modi-1 in the First in Man study. In animal studies, an aggressive tumour cell line confirmed that the two vimentin peptides eradicate tumour cells in a therapeutic, and therefore clinically relevant, setting. Remarkably, these responses were evident when tumours had reached a late stage of development.

Moditope vaccines have the potential to treat a wide variety of cancers. Scancell is currently further evaluating the initial indications for the first clinical trial with Modi-1 in terms of clinical need and market opportunity and based upon the possible addition of other peptide targets into the product.

Scancell is considering options for conducting the initial Modi-1 study in both Europe and the US and is designing the development and regulatory strategy to allow for either approach. The development programme will include manufacture plus toxicology and stability testing of the final formulated product. This data will form the basis of a clinical trial application, which is anticipated to be ready for submission in the first half of 2016.

Moditope® platform

Having exemplified the Moditope® platform with modified vimentin peptides, Scancell has been expanding the platform to other citrullinated tumour proteins that could be incorporated into Modi-1 or developed into a pipeline of other multiple-cancer immunotherapeutics. We are therefore pleased to announce today the identification of two further Moditope® protein targets, alpha-enolase and ING4.

Human alpha-enolase is a glycolytic enzyme that is overexpressed by lung, liver and other cancers. We have identified a citrullinated peptide within human alpha-enolase that induces a powerful and specific immune response and that elicits both increased survival and decreased tumour volume compared to control groups in animal models. Analysis of blood samples from donors has indicated that humans have a T cell repertoire that is able to recognise citrullinated alpha-enolase.

The tumour suppressor protein encoded by the ING4 gene plays a role in many cancer related processes. Two citrullinated peptides from human ING4 have been shown to induce specific T cell responses. Further studies are ongoing to evaluate the effect of these citrullinated peptides on tumour volume and survival. Both alpha-enolase and ING4 are believed to offer excellent prospects for future Moditope® immunotherapies.

About Scancell

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 being evaluated in a Phase 1/2 clinical trial. Data from the trial demonstrate that SCIB1, when used as monotherapy, has a marked effect on tumour load, produces a melanoma-specific immune response and highly encouraging survival trend without serious side effects.

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.

Pre-clinical data on a combination of SCIB1 and checkpoint inhibition (blockade of the PD-1 immune checkpoint pathway), has shown enhanced tumour destruction and significantly longer survival times than when either treatment was used alone.

Scancell has also identified and patented a series of modified epitopes that stimulate the production of killer CD4+ T cells 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.
