SCIB1 continues to deliver compelling survival data in melanoma

Scancell to present update at the Oxford Technology VCT AGM and Proactive Investors One2One Forum

Scancell Holdings plc, (‘Scancell’ or the ‘Company’) the developer of novel immunotherapies for the treatment of cancer, today provides an update from the SCIB1 Phase 1/2 clinical trial in malignant melanoma, the lead programme from the Company’s ImmunoBody® platform and will be presenting at the Oxford Technology VCT AGM and Proactive Investors One2One Forum later this week.

Dr Richard Goodfellow, CEO of Scancell, said: “SCIB1 continues to deliver compelling survival data in patients with resected Stage III/IV melanoma. It is particularly interesting to note that there has only been one new case of disease progression since November 2013 in the resected patients receiving 4mg doses of SCIB1, which gives us hope that SCIB1 might offer curative potential in this currently untreated patient group.”

Dr Keith Flaherty, Director of the Termeer Center for Targeted Therapy at the Massachusetts General Hospital Cancer Center and Professor of Medicine at Harvard Medical School, commented: “The SCIB1 overall survival and progression free survival data generated to date go well beyond established norms for this group of melanoma patients. We have a lot of enthusiasm for validating these results in subsequent trials.”

SCIB1 Survival Update

As of 27 June 2016, SCIB1 continues to deliver strong survival data:

  • Currently 19 of the 20 patients with resected tumours at study entry remain alive
  • One patient who first experienced disease progression in September 2013 died in April 2016, despite additional treatment with checkpoint inhibitors and radiation therapy
  • Of the 16 patients who received 2-4mg doses of SCIB1 Median observation time since entry is 46 months and 52 months since first diagnosis of metastatic disease
  • Only five patients have progressed and one has died
  • Only one new incidence of disease progression has been seen since November 2013
  • Of the four patients who received 8mg doses of SCIB1 (recruited after lower dose cohorts)
  • Median observation time since entry is 16 months and 21 months since first diagnosis of metastatic disease
  • None have progressed and none have died
  • As announced on 17 June 2016, treatment for the eight patients in the long-term continued dosing phase has been suspended due to the clinical trial supplies no longer being within the original specification
  • New SCIB1 material being manufactured to support a new study of SCIB1 in combination with a checkpoint inhibitor will also be made available to these continuation patients (subject to regulatory approval)
  • New SCIB1 material will be ready for use in approximately 9-12 months
  • Plans for the US clinical study of SCIB1 in combination with a checkpoint inhibitor remain on track
  • The final Clinical Study Report, which will be issued later this year, will provide safety, immunology and clinical data from all patients up to 29 October 2015 (the date of the last patient’s dose in the main study) to support our US regulatory submission

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. Data from the Phase 1/2 clinical 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 Drug Product Supply

Scancell Holdings Plc, (AIM:SCLP), the developer of novel Immunotherapies for the treatment of cancer, announces that it is suspending dosing with the current clinical trial supplies of SCIB1 with immediate effect.

Ongoing quality control analysis has revealed that the stored drug product is no longer within the original specification. In discussion with the MHRA Clinical Trials Unit, and with patient safety of primary importance, the Company has concluded that it is no longer suitable for further use, although no new side effects have emerged.

The suspension of dosing affects eight patients in the long term extension arm of the Phase 1/2 trial, SCIB1- 001 (out of the 35 patients that have been dosed), investigating SCIB1 as a monotherapy for the treatment of melanoma. All study investigators have been informed and their patients will be notified as soon as possible.

SCIB1-001 was originally started in 2010 with a prospectively planned treatment period of only six months. However, continuing encouraging results and an excellent side effect profile led to successive amendments to the clinical trial protocol to investigate increasing doses of the drug and eventually to examine a long term dosing regimen. As a result, some of the trial materials have now been stored for over 7 years.

The Company is planning to make a fresh batch of SCIB1 and has recently signed an agreement with a new GMP manufacturer. The primary reason for this is to support a new study of SCIB1 in combination with a checkpoint inhibitor, as previously announced. However, the Company also intends to make this material available to patients currently in the long term extension of SCIB1-001 who wish to continue receiving the drug. While it is expected that there will be a delay of approximately 9-12 months before the new SCIB1 material will be available for clinical use, it is anticipated that the anti-tumour response induced by SCIB1 should persist and eliminate any remaining tumour cells. Further doses of SCIB1 have been given for added protection to ensure the immune cells continue to patrol for any emerging cancer cells; subsequent administration of the new SCIB1 material should reactivate these memory immune cells to eliminate any recurring tumours.

Prof Poulam Patel, Chief Investigator for the SCIB1-001 clinical trial and Professor of Clinical Oncology at the University of Nottingham commented: “Results from the SCIB-001 trial to date have been very encouraging and SCIB1 clearly warrants further investigation as a potential treatment for melanoma.

However as patient safety is our primary concern, the deterioration of stored clinical trial material from the original specification necessarily means that dosing of SCIB1 must be suspended until new drug product becomes available.”

Dr Richard Goodfellow, CEO of Scancell added: “Patient safety has always been our primary responsibility. Although we have seen no new adverse events it is unfortunate, but nevertheless appropriate, that we suspend dosing of SCIB1 at this time while we work as quickly as possible to secure new supplies of this promising potential treatment for melanoma. Starting further efficacy studies with SCIB1 is only possible due to the results we have seen so far in the long-running SCIB1-001 study and we would again like to convey our thanks to the patients in that trial for their participation and support over the past 6 years.”

ImmunoBody® vaccine to be developed for the treatment of glioblastoma multiforme

Research undertaken by scientists at Nottingham Trent University and the University of Portsmouth

Scancell Holdings Plc, (AIM:SCLP), the developer of novel immunotherapies for the treatment of cancer, announces that researchers at Nottingham Trent University and the University of Portsmouth have initiated a new preclinical study aimed at developing a vaccine for the treatment of glioblastoma multiforme (GBM) by utilising Scancell’s ImmunoBody® technology platform.

GBM is the most common and aggressive form of glioma and carries a very poor prognosis. Around 5,000 people are diagnosed with a primary malignant brain tumour in the UK each year and GBM accounts for just over half of them. Treatments are limited and even with intensive chemotherapy patients have an average survival time of just 14 months.

Due to the highly aggressive nature of GBM and the lack of successful curative treatments to date, there is an urgent need for novel therapeutic approaches such as immunotherapy.

By using Scancell’s ImmunoBody® technology platform, scientists at Nottingham Trent University and the University of Portsmouth are aiming to develop a vaccine that stimulates protective immune responses against tumour molecules such as ‘HAGE’ and ‘TRP2’, which are proteins that are expressed in the cancer cells of GBM patients.

The vaccine treatment will be assessed for its ability to generate strong anti-GBM tumour immunity, as well as the ability to reduce and eradicate established tumours.

The researchers will also determine whether the vaccine stimulates HAGE and/or TRP2-specific immune cells in the blood of GBM patients that are capable of recognising the GBM tumours. This will demonstrate the ability of a patient’s immune system to identify and kill the cancer cells, providing insight into the effectiveness of the treatment.

The £95,000 study is being funded by the Headcase Cancer Trust, the only UK charity which dedicates its funding solely to research which aims to find a cure for GBM brain tumours.

Professor Lindy Durrant, Chief Scientific Officer of Scancell commented:

“We are keen to collaborate on this exciting project to add HAGE to our TRP-2/gp100 vaccine to target GBM. It is an aggressive disease and we believe the high avidity T cells generated by ImmunoBody® will be needed to control its growth.”

Dr Stephanie McArdle, a scientist in the John van Geest Cancer Research Centre at Nottingham Trent University, said:

“Vaccines can be extremely powerful when correctly formulated, so we are very hopeful that combining HAGE and TRP-2/gp100 with Scancell’s ImmunoBody® technology will lead to better disease outcomes.”

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.
