Subdivision of share capital and Placing to raise £1.73 million

Scancell Holdings plc, (‘Scancell’ or the ‘Company’) the developer of therapeutic cancer vaccines, is pleased to announce the following:

  • The proposed subdivision of each Existing Ordinary Share of 1p into 10 new Ordinary Shares of 0.1p each (the “Subdivision”); and
  • A placing to raise £1.73 million, before costs, by means of the issue of 34,575,410 new Ordinary Shares at 5 pence per share (the “Placing”) to fund the working capital of the Company.

The Directors consider the Placing and Subdivision to be in the best interests of the Company and its Shareholders as a whole. Since the Placing and Subdivision are conditional on the Company obtaining Shareholders’ approval the Directors have therefore convened a General Meeting for 10.45 a.m. on 25 July 2011 in order to allow Shareholders to consider, and, if thought fit, approve the Resolutions.

Professor Lindy Durrant, commented:

“We believe that, following completion of the Placing, we will have sufficient funding to complete the Phase I trials of our melanoma treatment and to advance the development of our series of new ImmunoBody® cancer vaccines to the pre-clinical proof of principle stage. After the Phase I clinical trial has been completed, and if the data is positive, the Company will seek to generate revenues from a commercial deal on the ImmunoBody® technology and will continue with the Phase II clinical trial. A successful outcome should present Scancell as an excellent acquisition opportunity with an exit remaining firmly on the agenda following the completion of the Phase II trial, expected early 2013.”

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, which entered clinical trials in 2010, is being developed for the treatment of melanoma.

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.

SCIB1: Safety Review and Dose Escalation

Scancell Holdings Plc, (AIM: SCLP), the developer of therapeutic cancer vaccines, is pleased to announce that the first group of patients receiving the lowest dose of SCIB1 (its DNA ImmunoBody® vaccine being developed for the treatment of melanoma) in the Phase I clinical trial has been evaluated by the Cohort Review Committee.

Following review of the safety data from the first three patients after three treatments, the Cohort Review Committee has approved escalation of the dose and recruitment of the next group of patients as planned.

The trial, which commenced in June 2010, is designed to evaluate the safety and tolerability of SCIB1 in patients with late stage melanoma and also to gather data on the effects of SCIB1 on tumour growth and cellular immune response.

Professor Lindy Durrant, CEO of Scancell Holdings and Professor of Cancer Immunotherapy at Nottingham University, commented: “We are pleased that the Cohort Review Committee has given us the go-ahead to escalate the dose of SCIB1. This initial data, combined with the recent recruitment of a fourth trial centre at Leeds and the approval by GTAC and MHRA for recruitment of earlier stage patients is a very encouraging development. There remains a pressing need for safe new treatments for this devastating disease and these developments have allowed us to make further progress towards this goal.”

Re: SCIB1 Clinical Trial Patient Recruitment

Scancell Holdings Plc, (AIM: SCLP), the developer of therapeutic cancer vaccines, is pleased to provide shareholders with an update on patient recruitment for its Phase I clinical trial of SCIB1, its DNA ImmunoBody® vaccine being developed for the treatment of melanoma. The trial has to date been conducted in three UK centres with Stage IV or inoperable Stage III melanoma patients.

Scancell has now obtained approval from the Gene Therapy Advisory Committee (‘GTAC’) and the Medicines and Healthcare products Regulatory Agency (‘MHRA’) Medicines Division to open a fourth UK site in Leeds. In addition, approval has been granted by GTAC and the MHRA to expand the patient population in the Phase I part of the study to include all patients with Stage III and Stage IV malignant melanoma.

As noted in the AGM Statement on 14 December 2010, patient recruitment has been slightly slower than originally anticipated. The Company sought approval to open a fourth centre and to be able to treat earlier stage patients in order to increase the rate of patient recruitment. In addition, it is hoped that the earlier stage patients might show a better immune response to SCIB1.

Professor Lindy Durrant, CEO of Scancell Holdings and Professor of Cancer Immunotherapy at Nottingham University, commented: “The approval to open a fourth centre in Leeds and to start recruiting patients with earlier stage disease is excellent news for Scancell. The Board remains confident that the Phase I/II clinical trial is on track to be completed by the end of 2012.”

AGM Statement

At the Annual General Meeting of Scancell Holdings Plc, (AIM: SCLP), to be held later today, David Evans, Chairman will give shareholders an update and review of the business. This will include the following statement:

This has been an exciting and busy year for Scancell in which the Company has successfully achieved all of its commercial and scientific aims in line with its strategy. Of particular note is the successful progression of Scancell’s first vaccine, SCIB1 for melanoma, which entered clinical trials in June 2010. The Company also successfully raised £2.5 million in April 2010 and moved from PLUS to AIM in July 2010.

SCIB1 Phase I Clinical Trial

Clearly, a move into clinical trials for SCIB1 represents an important milestone. This followed Clinical Trial Approval from the Gene Therapy Advisory Committee and by the Medicines and Healthcare Products Regulatory Agency Medicines Division. The approvals enabled Scancell to commence its Phase I clinical trial of SCIB1 in June 2010, to evaluate the safety and tolerability of SCIB1 in patients with late stage melanoma. To date, four patients have been enrolled on the trial which is currently taking place at three centres. Recruitment has been slower than anticipated due to the fact that a number of patients with advanced melanoma - the patients we require - are either being recruited into B-raf* studies or offered ipilimumab** on a compassionate use basis. By the time the patients have failed to respond to either (or both) of these treatments, they are often too ill to enter our study. Overall this has had an impact on the recruitment rates for the Phase I study, however the Company still expects to complete the clinical trial by the end of 2012.

To accelerate the advancement of the trial, two further centres will be opened, and Scancell has also filed protocol amendments to recruit patients with less severe disease. These earlier stage patients should make better immune responses which should ultimately have a positive effect on the outcome on our trial. The issue of patient recruitment is not expected to apply to the Phase II trial which will be conducted in less severely ill patients. The delay to patient recruitment may also have resource implications. Without Phase I clinical results (due in late 2011), it may be difficult to generate revenues from a commercial deal on the ImmunoBody® technology and it may therefore be necessary to augment the Company’s capital resources to complete the Phase II study.

Agreements and Collaborations

Scancell secured two key agreements during the year: a worldwide non-exclusive licensing agreement with the National Institutes of Health, an agency of the United States Department of Health and Human Services, for use of two melanoma antigens as key components of SCIB1; and, a licensing agreement with Cancer Research Technology Ltd, Cancer Research UK's commercialisation and development arm to use a human antibody for the development of new ImmunoBody® vaccines for any immunotherapy indication.

The Company also entered two important strategic collaborations: with ImmuneRegen BioSciences, Inc.®, a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTC BB:IRBS.OB) to investigate the synergy between ImmuneRegen's Homspera® and Scancell's ImmunoBody® vaccine technologies; and with immatics biotechnologies GmbH to explore the development of novel ImmunoBody® vaccines for colorectal cancer.

The Directors are pleased with Scancell’s progress during 2010 and look forward to updating shareholders on the future advancements in due course.

Notes to Editors

During the past year, data has emerged from studies of two new treatments in Stage IV patients.

* Firstly, a study of a B-raf inhibitor in patients with advanced melanoma demonstrated tumour regression in 80% of patients (although this did not result in a long-term survival advantage).

** Secondly, a Phase III trial of the anti-CTLA4 monoclonal antibody ipilimumab has demonstrated prolonged survival of Stage IV melanoma patients, with 23.5% still alive after two years. This is the first drug to have a positive impact on survival and is likely to receive approval for use in patients with advanced metastatic melanoma next year. Even if this drug is approved, this still leaves 75% of patients with no appropriate therapy and in potential need of our vaccine.

Collaboration With ImmuneRegen BioSciences® Yields Positive Results in Cancer Vaccine Studies

Scancell Holdings Plc, (AIM: SCLP), the developer of therapeutic cancer vaccines, announces that a treatment utilising a DNA vaccine based on its ImmunoBody® technology, in combination with ImmuneRegen BioSciences, Inc.®’s lead compound, Homspera®, has significantly improved the immune response of the vaccine in an animal model. Follow-up studies are currently being performed to optimize the effects of Homspera in enhancing the next generation of Scancell’s cancer vaccines.

Scancell recently announced the commencement of a Phase I clinical trial utilizing its SCIB1 product being developed for the treatment of melanoma. SCIB1 is a novel DNA vaccine being developed using Scancell’s patented ImmunoBody® technology. ImmunoBody® vaccines generate the high-avidity T-cells that kill cancer cells, which may overcome the current limitations of most cancer vaccines. A unique advantage of Scancell’s Immunobody® technology is that it specifically targets dendritic cells, leading to a significant enhancement of the immune response.

ImmuneRegen’s Homspera has previously been found to improve the efficacy of a melanoma cancer vaccine in mice, resulting in persistent and specific immune responses associated with inhibition of melanoma tumor growth. Additionally, previous studies have demonstrated efficacy of Homspera in enhancing immune responses to infectious disease vaccines, such as influenza. Both applications are being aggressively developed by ImmuneRegen in combination with significant academic and industry partners.

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

“I am pleased with the results achieved by this collaboration to date and look forward to continuing to work with ImmuneRegen as we progress with follow-up studies.”

Hal Siegel Ph.D., Chief Scientific Officer of ImmuneRegen, commented:

“We are pleased to see if we can positively augment immune responses elicited by Scancell’s ImmunoBody® vaccines. Based on our previous demonstration of enhanced dendritic cell responses to TRP2-encoding DNA vaccine following Homspera exposure, Scancell’s ImmunoBody® vaccine technology presents a very desirable developmental opportunity. We are very happy with our ongoing relationship and recognize that ongoing studies could potentially benefit both companies.”
