About Scancell

Scancell is developing novel therapeutic vaccines for the treatment of cancer and infectious diseases based on its groundbreaking ImmunoBody® technology platform. Scancell’s first cancer vaccine SCIB1 is being developed for the treatment of melanoma and has recently entered clinical trials.

Treating cancer by vaccination allows small non-toxic doses of a vaccine to be administered to a patient, stimulating an immune response. Effective cancer vaccines need to target dendritic cells to 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.

A limitation of many cancer vaccines currently in development is that they cannot specifically target dendritic cells in vivo. Several groups have demonstrated successful vaccination by growing dendritic cells ex vivo, pulsing them with tumour antigens and re-infusing them. However, this procedure is patient specific, time consuming and expensive. Scancell has developed its breakthrough patent protected ImmunoBody® technology to overcome these limitations.

An ImmunoBody® is a human antibody or fusion protein engineered to express helper cell and CTL epitopes from tumour antigens over-expressed by cancer cells. Antibodies are ideal vectors for carrying T cell epitopes from tumour antigens as they have long half-lives and can effectively target dendritic cells via their Fc receptors, allowing efficient stimulation of both helper and CTL responses.

The Immunobody® technology can be adapted to provide the basis for treating any tumour type and may also be of potential utility in the development of vaccines against hepatitis, HIV and other chronic infectious diseases.

Withdrawal from PLUS and Admission to AIM

The Board of Scancell Holdings plc, (PLUS:SCLP), the developer of therapeutic cancer vaccines, is pleased to announce that it intends to apply for the Company’s Ordinary Shares to be admitted to trading on AIM and, immediately prior to the Admission to AIM, it intends to withdraw the Company’s Ordinary Shares from trading on PLUS.

During 2010, the Company has raised £2.54 million, before expenses, to fund its foreseeable working capital requirements. The Directors believe that the existing funds held by or available to the Group together with future anticipated revenues will be sufficient to allow completion of the Phase I/IIa clinical trial of SCIB1, its lead melanoma therapeutic vaccine.

The Ordinary Shares of the Company were originally admitted to trading on PLUS in September 2008. However, now that the Company has further strengthened its financial position and progressed the development of SCIB1, the Directors believe that it would be in the best interests of the Company and its shareholders for the Ordinary Shares to be admitted to trading on the AIM market of the London Stock Exchange.

The Directors believe that this represents a natural transition for the Company and that the potential benefits of an AIM listing will include an increased public profile for the Company.

Under the AIM Rules, prior to Admission, the Company is required to publish an admission document. The Company is therefore sending an admission document to Shareholders to inform them that the Ordinary Shares of the Company will be withdrawn from trading on PLUS from the close of business on 29 July 2010 and that the Ordinary Shares of the Company are expected to be admitted to trading on AIM at 8.00 a.m. on 30 July 2010.

The Directors of the issuer accept responsibility for this announcement.

Research collaboration with immatics to develop novel ImmunoBody® vaccines for colorectal cancer

Scancell Holdings Plc, (PLUS:SCLP), the developer of therapeutic cancer vaccines, today announces a research collaboration with immatics biotechnologies GmbH (“immatics”) to explore the development of novel ImmunoBody® vaccines for colorectal cancer.

immatics discovers and develops tumor-associated peptides (TUMAPs) for the immunotherapy of cancer. TUMAPs with the highest specificity for particular cancers are identified directly from primary human tumour tissue samples. From thousands of identified TUMAPs the most suitable ones are selected and combined to a single multi-peptide product to form a therapeutic cancer vaccine. The goal is to provoke a number of specific T-cell responses which finally result in the destruction of tumour cells presenting the TUMAPs.

immatics’ most advanced product, IMA901, has been evaluated in a Europe-wide multi-centre Phase II clinical trial in renal cancer. Positive data of this Phase II study have recently been published at the ASCO 2010 meeting. immatics’ pipeline also includes IMA910 for the treatment of colorectal carcinoma which has recently entered a large Phase I/II clinical trial.

Scancell’s first vaccine using its patented ImmunoBody® technology is SCIB1, a novel DNA vaccine being developed for the treatment of melanoma, which is currently in Phase 1 clinical trials. An advantage of Scancell’s Immunobody® platform is that it specifically targets dendritic* cells, leading to a significant enhancement of the immune response. This enhanced immune response against TRP-2 (a melanoma protein called Tyrosinase-Related Protein 2) is anticipated to lead to the inhibition and regression of both primary and metastatic melanoma tumour growth.

In the research collaboration with immatics, colorectal cancer-specific TUMAPs will be incorporated into ImmunoBody® constructs to create ImmunoBody® vaccines targeted towards colorectal cancer. If the research project is successful, immatics and Scancell will explore the further development of any product candidates.

Paul Higham, CEO of Immatics said

“We are very pleased to enter this research collaboration with Scancell as the colorectal TUMAPs identified by immatics have the potential to complement and enhance Scancell's ImmunoBody technology. We eagerly await the results.”

Professor Lindy Durrant, Chief Executive Officer of Scancell, commented:

“Our research collaboration with immatics will create the opportunity to bring together two world class technologies. We will be working together with immatics to evaluate the combination of the immatics’ TUMAP technology with Scancell’s ImmunoBody® technology for the development of novel vaccines for the treatment of colorectal cancer.”

SCIB1 Phase I Trial Commences - First Patient Treated

Scancell Holdings Plc, (PLUS:SCLP), the developer of therapeutic cancer vaccines, today announces the enrolment and treatment of the first patient in its multicentre Phase I clinical trial of SCIB1, its DNA ImmunoBody® vaccine being developed for the treatment of melanoma. The trial will evaluate the safety and tolerability of SCIB1 in patients with late stage melanoma.

The trial, which is commencing on schedule, will be in nine, Stage IV or inoperable Stage III patients and is being conducted in three UK centres. All patients in the clinical trial will be treated with Scancell’s SCIB1 ImmunoBody® vaccine, delivered by Ichor Medical Systems’ TriGrid™ electroporation delivery device.

ImmunoBody® vaccines generate the high-avidity T-cells* that kill cancer cells, which may overcome the current limitations of most cancer vaccines. In vivo electroporation is widely regarded as an effective method of enhancing the potency of DNA vaccines by up to 100-fold compared to conventional methods of delivery.

Advanced melanoma currently has a very poor prognosis with late stage (stage IV) disease having a median survival of approximately six months. According to the World Health Organisation, 132,000 melanoma skin cancers occur globally each year and the incidence is increasing, especially in the United States, Europe and Australia.

Professor Lindy Durrant, CEO of Scancell Holdings and Professor of Cancer Immunotherapy at Nottingham University, commented:

“This is the first time we will be taking the SCIB1 ImmunoBody® vaccine into patients with late stage melanoma and follows our very positive research studies with the vaccine against this deadly form of cancer. We are very excited about the prospects for SCIB1 and are very pleased that it has moved a step closer to becoming available for the treatment of cancer patients.”

Professor Poulam Patel, Lead Researcher, commented:

“Advanced melanoma is one of the most deadly cancers we have and there is an urgent need for new treatments. The data from the laboratories looks very promising and we’re very excited to take SCIB1 into the clinic.”

David Evans, Chairman of Scancell Holdings, commented:

“The beginning of enrolment in the Phase I trial for SCIB1 is a key milestone for Scancell and we are delighted that the Company is continuing in its progress.”

The Directors of the issuer accept responsibility for this announcement.

*High avidity T-cells – A type of white blood cell composed of CTL and Helper cells. CTL cells recognise and kill tumour or virally infected cells, Helper cells recognise and secrete molecules to alert the immune system to the presence of a tumour or virally infected cell. Avidity measures the strength of the T-cell interaction.

About Scancell

Scancell is developing novel therapeutic vaccines for the treatment of cancer and infectious diseases based on its groundbreaking ImmunoBody® technology platform. Scancell’s first cancer vaccine, SCIB1, is being developed for the treatment of melanoma and will enter clinical trials in 2010.

Treating cancer by vaccination allows small non-toxic doses of a vaccine to be administered to a patient, stimulating an immune response. Effective cancer vaccines need to target dendritic cells to 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.

A limitation of many cancer vaccines currently in development is that they cannot specifically target dendritic cells in vivo. Several groups have demonstrated successful vaccination by growing dendritic cells ex vivo, pulsing them with tumour antigens and re-infusing them. However, this procedure is patient specific, time consuming and expensive. Scancell has developed its breakthrough patent protected ImmunoBody® technology to overcome these limitations.

An ImmunoBody® is a DNA vaccine encoding a human antibody or fusion protein engineered to express helper cell and CTL epitopes from tumour antigens over-expressed by cancer cells. Antibodies are ideal vectors for carrying T cell epitopes from tumour antigens as they can effectively target dendritic cells via their Fc receptors, allowing efficient stimulation of high avidity and high frequency helper and CTL responses.

The ImmunoBody® technology can be adapted to provide the basis for treating any tumour type and may also be of potential utility in the development of vaccines against hepatitis, HIV and other chronic infectious diseases.
