Immunocore's IMCgp100 Starts Phase I Trial for the Treatment of Uveal Melanoma

OXFORD, England, March 30, 2016 /PRNewswire/ --

Immunocore, a world-leading biotechnology company developing novel T cell receptor (TCR) based biological drugs to treat cancer, infectious diseases and autoimmune disease, today announced that it has recruited the first patient into a Phase I monotherapy trial of its lead programme, IMCgp100, for the treatment of uveal melanoma.

Uveal melanoma, a rare disease in which cancer cells form in the tissues of the eye, comprises approximately 3% of all melanomas, and is the primary intraocular malignancy of the adult eye. There are currently no effective treatments on the market for this debilitating disease.

The trial will include three Phase I escalation cohorts to determine the optimal dose for the pivotal Phase II study, which is expected to start in 2016, and will take place at a number of leading centres around the world.

The US Food and Drug Administration (FDA) in January 2016 granted Orphan Drug Designation to IMCgp100 for the treatment of uveal melanoma. Orphan Drug status qualifies Immunocore for a number of development incentives to enable rapid progress in the clinical development of IMCgp100 in advanced uveal melanoma, its most advanced therapeutic.

The Orphan Drug Designation programme provides orphan status to drugs and biologics, defined as those intended for the safe and effective treatment, diagnosis or prevention of rare diseases or disorders where the prevalence of the condition affects no more than 200,000 people in the US.  

IMCgp100 is Immunocore's wholly-owned and most advanced ImmTAC (Immune mobilizing mTCR Against Cancer), currently in Phase I/IIa clinical trials for the treatment of late stage metastatic melanoma. Promising results from the Phase I/IIa clinical trial of IMCgp100 in advanced cutaneous and uveal melanoma patients demonstrated that responses were durable, with five objective responses to date, two of which are partial responders in patients with uveal melanoma. To date, more than 85 patients have been treated with IMCgp100.

Christina Coughlin, Chief Medical Officer of Immunocore, commented: "Advanced uveal melanoma is a rare and devastating disease for which there are currently no effective treatment options. IMCgp100 has shown some promising signs of early clinical activity in this disease setting and could be an effective treatment for this group of patients. We are excited to be able to explore the activity of IMCgp100 in this clinical study in advanced uveal melanoma."

About Immunocore 

Immunocore is one of the world's leading biotechnology companies, with a highly innovative immuno-oncology platform technology called ImmTACs. ImmTACs are a novel class of biologic drugs based on the Company's proprietary T cell receptor (TCR) technology which have the potential to treat diseases with high unmet medical need including cancer, infectious diseases and autoimmune diseases.  Immunocore, based on decades of world-leading scientific innovation in the discovery of HLA targets and T cell receptor technology, has a pipeline of wholly-owned and partnered ImmTAC programmes with robust clinical data, validated by collaborations with world-leading pharmaceutical companies.  Immunocore aims to leverage the utility of its platform across a wide range of indications to become a Premier Biotech company and world-leader in its field.

Immunocore's world-leading science and strong IP position has attracted major pharmaceutical companies including Genentech, GlaxoSmithKline, MedImmune, the biologics division of AstraZeneca, via discovery collaborations, as well as a co-discovery and co-development partnership with Lilly. The Company has also entered into combination trials with its lead programme, IMCgp100 in melanoma, with MedImmune and Lilly.   Founded in 2008 originally out of Oxford University and headquartered outside Oxford with US offices outside Philadelphia, Immunocore now has more than 200 staff. Immunocore's current investors are well-renowned, leading international institutions including Woodford Investment Management, Malin Corporation, Eli Lilly and Company, RTW Investments, Fidelity Management & Research Company as well as other private shareholders.

About ImmTACs 

Immunocore's proprietary technology is focused on small protein molecules called ImmTACs (Immune mobilising mTCR Against Cancer) that enable the immune system to recognise and kill cancerous or bacterially/virally infected cells. Immunocore's ImmTACs, a new class of drug with ultra-high affinity for intracellular cancer targets, are synthetic, soluble T cell receptors (TCRs) that recognise diseased cells containing disease specific targets. The ImmTACs enable circulating T-cells to selectively identify and kill diseased cells.  The ImmTAC platform is unique in its high specificity and potency and broad applicability to a wide range of intracellular targets and disease indications. ImmTACs can access up to nine-fold more targets than typical antibody-based therapies, including monoclonal antibodies.

TCRs naturally recognise diseased cells and Immunocore's world-leading competitive advantage is its ability to engineer high affinity TCRs and link them to an antibody fragment that activates a highly potent and specific T cell response to recognise and destroy cancer cells. The most advanced ImmTAC, IMCgp100, is currently in Phase I/IIa clinical trials for the treatment of late stage melanoma. Immunocore has a growing internal pipeline of ImmTACs addressing many different cancer types and has developed a broad database of intracellular cancer targets.  

ImmTACs can address a significantly larger range of disease indications than currently respond to existing immuno-oncology agents and combine the characteristics of very high potency, encouraging safety and low cost of goods.

About Uveal Melanoma 

Melanoma arises from pigment containing cells (melanocytes) present in the skin, eye and mucus membranes.  Melanoma most frequently occurs in the skin, however ocular melanoma arises from pigmented cells in the eye. The primary cause of melanoma is thought to be radiation induced DNA damage from ultraviolet (UV) light exposure.  Melanoma is the most deadly of skin cancers.  Globally, in 2012, melanoma occurred in 232,000 people and resulted in 55,000 deaths. Uveal melanoma (UM) is a rare type of melanoma where the incidence has ranged from 5.3 to 10.9 cases per million (Singh 2003). Despite its rare incidence rate (representing approximately 3% of melanoma cases, approximately 4000 cases globally per year), UM is the most frequent primary intraocular malignancy of the adult eye in 85% of cases (Patel 2011, Maio 2013). Advanced uveal melanoma currently has no effective treatment options.
