Scancell to conduct Phase II checkpoint inhibitor combination study with SCIB1 with leading US melanoma specialists

Harvard, MD Anderson, Memorial Sloan Kettering, University of Colorado clinical team to lead checkpoint inhibitor combination trial with SCIB1 

Aim of study will be to improve objective response to anti-PD-1 monotherapy without additional toxicity.

Scancell Holdings Plc, (AIM:SCLP), today announced formation of its core US investigator team to lead a Phase II checkpoint inhibitor combination study with Scancell’s lead cancer vaccine SCIB1. Dr Keith Flaherty, M.D., Director of the Termeer Center for Targeted Therapy at Massachusetts General Hospital and Associate Professor at Harvard Medical School has been named the Principal Investigator. Joining Dr Flaherty are Dr Jennifer Wargo of the Department of Surgical Oncology at MD Anderson, Dr Michael Davies of the Department of Melanoma Oncology at MD Anderson, Dr Paul Chapman in the Melanoma/Sarcoma Service at Memorial Sloan Kettering and Dr Rene Gonzalez of the Division of Medical Oncology at University of Colorado.

Dr Keith Flaherty, Associate Professor, Medicine, Harvard Medical School and Director of Developmental Therapeutics, Henri and Belinda Termeer Center for Targeted Therapies, Massachusetts General Hospital said: “Based on the scientific and translational research behind SCIB1, I believe there is a compelling case for further investigation in both the metastatic and adjuvant melanoma settings. Despite meaningful recent advances in the treatment of this disease there still remains a significant unmet medical need. I am very excited to be working with Scancell and my other colleagues in the investigator team to bring this innovative treatment to patients."

Dr Paul Chapman, Dept. of Medicine, Memorial Sloan Kettering Cancer Center added: “SCIB1 represents a potentially important complement to checkpoint inhibitor therapy. Despite the unquestionable clinical utility of anti-PD-1 drugs, only around 30% of patients respond to treatment. Available data supports testing the hypothesis that the use of SCIB1 in combination with these agents may increase the number of patients responding to treatment and prolong progression free survival without the additional burden of significant further side effects.”

Dr Richard Goodfellow, Joint CEO of Scancell, said: “The latest data on SCIB1, both in terms of the unprecedented survival of Stage 3/4 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 regimen sets the stage for an expanded clinical trial programme. We are delighted to have secured the help and support of such a prestigious group of US specialists, led by Dr Flaherty.”

The clinical study will assess the impact of adding SCIB1 to a checkpoint inhibitor 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 trial will enrol approximately 80 Stage 3/4 metastatic melanoma patients and commence in the second half of 2016, ending around 18 months later.

Notes to Editors

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.

Results of AGM

Scancell Holdings Plc, (AIM:SCLP), the developer of novel immunotherapies for the treatment of cancer, announces that all resolutions proposed at the Annual General Meeting held today were duly passed.

AGM Business and R&D Update

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.”

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.”

Presentation entitled: ‘‘Peptides or DNA vaccines? Could ImmunoBody® be the answer?”

Scancell Holdings plc (‘Scancell’ or the ‘Company’), the developer of novel immunotherapies for the treatment of cancer, today announces that Dr Stephanie McArdle, Senior Research Scientist from The John van Geest Cancer Research Centre, Nottingham Trent University will be giving a presentation entitled: ‘‘Peptides or DNA vaccines? Could ImmunoBody® be the answer?” at the Cancer Vaccines Conference in London, 16-17 September 2015. The presentation will cover the criteria for designing an effective cancer vaccine, with particular reference to Scancell’s ImmunoBody®.

ImmunoBody® is a DNA plasmid that encodes a human antibody or fusion protein engineered to express helper cell and CTL epitopes from tumour antigens over-expressed by cancer cells. Unlike current vaccine approaches that rely on a single activation mechanism, ImmunoBody® vaccines activate dendritic cells through two distinctly different and complementary mechanisms that maximise T cell activation and avidity: direct- and indirect/cross-presentation.

Scancell’s first ImmunoBody®, SCIB1, is being developed for the treatment of melanoma and is currently being evaluated in a Phase 1/2 clinical trial. The latest data suggests that SCIB1 may have the potential to significantly extend survival times in patients, especially in those with resected disease. The John van Geest Cancer Research Centre is also engaged on collaborative research with Scancell on the development of an ImmunoBody® for the treatment of prostate cancer targeting PAP (prostate acid phosphatase).

Prof Lindy Durrant, Joint Chief Executive Officer of Scancell, said: “Cancer vaccines help boost the immune system to recognise and destroy cancer cells. The design of a cancer vaccine is extremely important and needs to deliver very high avidity T cells in order to be effective. ImmunoBody® delivers high avidity T cells by combining the advantages of DNA and peptide vaccines in one molecule. We are delighted to be working with The John van Geest Cancer Research Centre on this exciting project.”

Notes to Editors

SCIB1 mechanism of action
SCIB1 is a DNA ImmunoBody® immunotherapy encoding a human IgG1 antibody, with three epitopes from gp100 and one from TRP-2 engineered into its CDR regions. This immuno-stimulatory antibody targets dendritic cells in vivo via the high affinity Fc receptor, CD64, and stimulates high avidity T cells. Extensive research studies suggest SCIB1 ImmunoBody® has a dual mechanism of action that combines crosspresentation with direct-presentation. This results in amplification of the immune response to induce high frequency, high avidity T cells which translates into a potent anti-tumour response.

Scancell and ImmunID announce collaboration to predict SCIB1 responders using ImmunTraCkeR®

Nottingham, UK and Grenoble, France, 30 July 2015 - Scancell Holdings plc (‘Scancell’ LSE:AIM SCLP), the developer of novel immunotherapies for the treatment of cancer, and ImmunID, an immune molecular diagnostics company, today announce an agreement to collaborate on a research project aimed at predicting which patients will respond best to SCIB1 treatment.

The study will use ImmunID’s flagship clinical product, ImmunTraCkeR®, before and during treatment, to assess the immune-modulatory effect of Scancell’s SCIB1 ImmunoBody® vaccine in patients with Stage III/IV metastatic melanoma. The ImmunTraCkeR® assay will be used to:

  • understand pre-existing immunity of Stage III/IV metastatic melanoma patients;
  • monitor T cell diversity over time in order to assess immune-modulatory effect of the SCIB1 cancer vaccine;
  • make a preliminary assessment of ImmunTraCkeR® acting as a predictor of response to SCIB1; and
  • identify any other predictive or prognostic clinical value of T cell diversity.

ImmunID has been a pioneer in the field of immune molecular diagnostics for a decade. Its clinical product ImmunTraCkeR® evaluates a patient’s immune status, from a simple liquid biopsy (5ml EDTA blood), based on T lymphocyte repertoire diversity. ImmunID has developed and patented the ImmunTraCkeR® diagnostic assay and is expanding its clinical utility to become the general immune companion diagnostics for all immune therapies and especially immune checkpoint agents.

Scancell’s first ImmunoBody®, SCIB1, is being developed for the treatment of melanoma and is currently being evaluated in a Phase 1/2 clinical trial. The latest data suggests that SCIB1 may have the potential to significantly extend survival times, especially in patients with resected disease.

Dr Richard Goodfellow, Joint Chief Executive Officer of Scancell, said: “We are delighted to be working with ImmunID. This collaboration will provide an insight into T cell diversity in patients treated with our SCIB1 vaccine and their response to the treatment over time. We believe that ImmunID’s ImmunTraCkeR® test will deliver valuable data that will provide deeper insight into the strong clinical results we have generated to date with our novel treatment for metastatic melanoma.”

Dr Bernhard Sixt, Chairman and CEO of ImmunID, added: “We see this collaboration as an opportunity to provide Scancell with a relevant tool to measure the patient’s immune status in the rapidly growing immunooncology field, while also widening the clinical value of our ImmunTraCkeR® assay. Ultimately, ImmunTraCkeR® may be used to predict which patients respond best to treatment.”

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.

SCIB1 mechanism of action
SCIB1 is a DNA ImmunoBody® immunotherapy encoding a human IgG1 antibody, with three epitopes from gp100 and one from TRP-2 engineered into its CDR regions. This immuno-stimulatory antibody targets dendritic cells in vivo via the high affinity Fc receptor, CD64, and stimulates high avidity T cells. Extensive research studies suggest SCIB1 ImmunoBody® has a dual mechanism of action that combines crosspresentation with direct-presentation. This results in amplification of the immune response to induce high frequency, high avidity T cells which translates into a potent anti-tumour response.

About ImmunID
ImmunID adds precision to the immuno-oncology revolution by personalizing immunotherapy. With its decade-long experience in immune molecular diagnostics, ImmunID provide doctors with clinically meaningful data on the highly complex immune system to select the right therapy for individual patients and to monitor their response. ImmunID’s flagship CE-marked product, ImmunTraCkeR®, evaluates the patient’s immune status based on the T lymphocyte diversity, from a simple liquid biopsy. The company is establishing ImmunTraCkeR® as the general immune companion diagnostic assay for immune checkpoint inhibitors and other immunotherapies. In addition, ImmunID collaborates with pharma and biotech companies to optimize the development of their next-generation immunotherapies. ImmunID is ISO 9001 and ISO 13485 certified and runs a CAP-accredited laboratory in the MINATEC high-tech campus in Grenoble, France.

About ImmunTraCkeR®
ImmunTraCkeR® is a proprietary CE-marked immune molecular diagnostics assay, which evaluates a patient’s immune status in the blood based on combinatorial T cell diversity. Unlike most companion diagnostics tests, ImmunTraCkeR® is patient-specific rather than drug- or disease-specific, as it approaches the disease from the patient’s own immune system perspective. ImmunTraCkeR® provides information on the patient’s complex immune profile to evaluate clinical benefit or risk under treatment with immunotherapies. ImmunTraCkeR® may ultimately be used as immune companion diagnostics and answer the urgent medical need for efficient patient stratification tools in melanoma and other solid cancers.

Patient recruitment completed for SCIB1 Phase 1/2 clinical trial

SCIB1 continues to deliver strong survival data in resected melanoma patients with Stage III/IV disease

Scancell Holdings plc (‘Scancell’ or the ‘Company’), the developer of novel immunotherapies for the treatment of cancer, today announces 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 five 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 designed trial to determine the dose for Part 2. While the primary objective of the study is to access safety and tolerability, the study is also assessing immune response and anti-tumour activity, and the ability of SCIB1 to delay or prevent disease recurrence in patients with resected disease.

In total, 35 patients have now been treated with SCIB1, including ten patients at the higher 8mg dose. Six patients remain on long-term treatment and have received between one and nine additional 4mg or 8mg doses of SCIB1 every three to six months.

As with previously reported data, 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 including the four patients on the 8mg dose. The median survival time in the 16 patients with resected disease who received 2-4 mg doses of SCIB1 is now 35 months.

The last patient in the formal six month study will be dosed in October this year after which the Company will analyse the data and prepare a clinical study report. Patients on long-term continuation treatment will continue to be dosed for up to five years from the start of their treatment regime.

Dr Richard Goodfellow, Joint Chief Executive Officer of Scancell, said: “With the recruitment of the SCIB1 Phase 1/2 melanoma trial coming to a close, we continue to see highly encouraging survival times and melanoma-specific immune responses in patients, especially those with resected tumours. We believe that our ImmunoBody® platform offers melanoma patients a new treatment option that has the potential to extend life expectancy and improve their quality of life. We look forward to reporting the final results of the study in due course.”
