Scancell Establishes Clinical Advisory Board and Provides Update on Modi-1 Progress

Appoints six world class clinical oncologists to guide the Moditope® clinical development strategy

Modi-1 manufacturing and toxicity testing underway to support anticipated start of Phase 1/2 study in

Q1 2020

Scancell Holdings plc, the developer of novel immunotherapies for the treatment of cancer, today announces that it has appointed six world-leading clinicians to establish its Clinical Advisory Board ("CAB"). The Board will be chaired by Professor Robert Coleman and will provide strategic guidance and support as the Company prepares for its lead Moditope® candidate, Modi-1, to enter the clinic in Q1 2020 in multiple tumour types, including head and neck, breast and ovarian cancer.

The CAB comprises: Professor Robert Coleman, Emeritus Professor of Medical Oncology at Weston Park Hospital and the University of Sheffield; Professor Christian Ottensmeier, Professor of Experimental Cancer Medicine at the University of Southampton; Professor Poulam Patel, Professor of Clinical Oncology at the University of Nottingham and Honorary Consultant Medical Oncologist at the Nottingham University Hospitals NHS Trust; Professor Iain McNeish, Professor of Oncology and Head of the Division of Cancer within the Department of Surgery and Cancer, Imperial College London; Professor David Miles, Lead Clinician for breast cancer at Mount Vernon Cancer Centre; and Professor Stephen Chan, Director of Clinical Trials in Breast Cancer and Gynaecological Cancer at Nottingham University Hospital.

The Company also provides an update on progress towards initiating the Modi-1 Phase 1/2 clinical trial.

· Good Manufacturing Practice (GMP) synthesis of the bulk Modi-1 peptide conjugates is underway at the PolyPeptide Group's facilities in The Netherlands.

· The Company signed an agreement at the end of April 2019 with AMRI (Glasgow, UK), a global contract and manufacturing organisation, to formulate, manufacture and package the Modi-1 GMP final product for clinical testing.

· The preclinical toxicity testing programme required prior to the start of the clinical trial commenced in April 2019 and is anticipated to be completed during H2 2019.

Scancell's Moditope® platform acts by stimulating the production of CD4 T cells using citrullinated tumour-associated peptide epitopes. This technology overcomes the immune suppression induced by tumours themselves, allowing activated T cells to seek out and kill tumour cells that would otherwise be hidden from the immune system. Previous pre-clinical data demonstrated that conjugation of the Modi-1 peptides to Amplivant® enhances anti-tumour immune responses 10-100 fold and resulted in highly efficient tumour eradication, including protection against tumour recurrence.

Dr Cliff Holloway, Chief Executive Officer, Scancell, said:

"We are delighted to welcome all six experienced clinicians to our Clinical Advisory Board and the creation of this Board is part of our wider strategy to fully develop and deliver the full potential of the Moditope® platform across multiple tumour types. The initial focus of the Board will be to inform the clinical strategy for the planned Modi-1 clinical trial and to ensure the best possible outcome in several solid tumour indications, including ovarian cancer, head and neck cancer, and triple negative breast cancer. Significant progress has been made towards completing the GMP manufacture of the Modi-1 product and the preclinical testing required prior to the anticipated start of the trial early in 2020."

Chair of the Clinical Advisory Board, Professor Robert Coleman said:

"I am pleased to be working alongside Christian, Poulam, Iain, David and Stephen, who collectively have long, established track records in scientific and clinical research in oncology. I am looking forward to chairing the Clinical Advisory Board and working closely with my Board colleagues and the Scancell team to realise the full potential of Scancell's Moditope® immunotherapy platform through future clinical development."

About Scancell

Scancell is developing novel immunotherapies for the treatment of cancer based on its ImmunoBody® and Moditope® technology platforms.

ImmunoBody® vaccines target dendritic cells and stimulate both parts of the cellular immune system. They can be used as monotherapy or in combination with checkpoint inhibitors. This platform has the potential to enhance tumour destruction, prevent disease recurrence and extend survival.

· SCIB1, the lead programme, is being developed for the treatment of melanoma. A phase 1/2 clinical trial has so far successfully demonstrated survival data of more than five years.

· SCIB2 is being developed for the treatment of non-small cell lung cancer and other solid tumours. Scancell has entered into a clinical development partnership with Cancer Research UK for SCIB2.

Moditope® represents a completely new class of potent and selective immunotherapy agents based on stress-induced post-translational modifications (siPTM). It stimulates the production of killer CD4 T cells which overcome the immune suppression induced by tumours, allowing activated T cells to seek out and kill tumour cells that would otherwise be hidden from the immune system. Moditope® alone, or in combination with other agents, has the potential to treat a wide variety of cancers.

· Modi-1 is being developed for the treatment of solid tumours including triple negative breast cancer, ovarian cancer and head and neck cancer.
