On April 16, 2015 AstraZeneca reported that MedImmune has entered into a collaboration to conduct clinical trials in immuno-oncology with Immunocore (Press release, AstraZeneca, APR 16, 2015, View Source;medimmune-and-immunocore-announce-new-collaboration [SID:1234503020]). Schedule your 30 min Free 1stOncology Demo! Under the terms of the agreement, Immunocore will conduct a Phase Ib/II clinical trial combining MedImmune’s investigational checkpoint inhibitors MEDI4736 (anti-PD-L1) and/or tremelimumab (anti-CTLA-4) with IMCgp100, Immunocore’s lead T-cell receptor-based investigational therapeutic, for the potential treatment of patients with metastatic melanoma. MedImmune has an exclusive relationship with Immunocore for the development of IMCgp100 in combination with MEDI4736 and/or tremelimumab, and will have first right of negotiation for the future commercial development of these combinations for tumours expressing glycoprotein 100 (gp100), a tumour-associated antigen. Know more, wherever you are: Immunocore and MedImmune will collaborate to establish a dosing regimen for IMCgp100 combined with MEDI4736 and/or tremelimumab within the Phase Ib study. The Phase II study will assess the safety and efficacy of the different combinations.

The companies have a pre-existing research collaboration and licensing agreement, announced in January 2014, to develop novel cancer therapies using Immunocore’s Immune Mobilising Monoclonal T-Cell Receptor Against Cancer (ImmTAC) technology.
"We are pleased to expand our partnership with Immunocore, a leader in the discovery and development of novel T-cell receptor-based drugs, to include this combination clinical trial in melanoma," said Dr. Ed Bradley, Senior Vice President and Head of the Oncology Innovative Medicines unit at MedImmune. "Immuno-oncology is a priority area for us and by employing combinations with biological synergies, we believe we have the potential to enhance treatment effectiveness and ultimately to see improved overall survival rates. Our partnership with Immunocore is further evidence of our belief that combination therapies have the potential to be one of the most effective ways of treating cancer."
"We are excited to deepen our relationship with MedImmune through this combination study agreement. We look forward to a successful partnership in the development of novel combination treatments in metastatic melanoma, which we believe have the potential to be best-in-class treatments," said Eliot Forster, Chief Executive Officer of Immunocore.
MEDI4736, tremelimumab and IMCgp100 are members of a new class of cancer treatments known as immunotherapies, which are designed to enhance the body’s own immune system in fighting cancer.
AstraZeneca and MedImmune have a broad programme of immuno-oncology combination trials underway and planned to address multiple immune pathways, harnessing the company’s own extensive pipeline and working in partnership to explore the significant potential of immunotherapies in transforming the way cancer patients are treated.
NOTES TO EDITORS
About IMCgp100 and 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 cells.
ImmTACs have 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 and has very high specificity and potency as well as broad applicability to a wide range of intracellular targets. ImmTACs can access up to nine-fold more targets than typical antibody-based therapies, including monoclonal antibodies.
The most advanced ImmTAC, IMCgp100, is currently in Phase IIa clinical trials for the treatment of late stage melanoma. Following completion of a Phase I study at the end of 2013, which showed promising results with an encouraging safety profile and early signs of efficacy, Immunocore initiated a Phase IIa study to optimize the dosing regimen of IMCgp100. Immunocore has a growing internal pipeline of ImmTACs addressing many different cancer types and has developed a broad database of intracellular cancer targets.
About MEDI4736
MEDI4736 is an investigational human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumours avoid detection by the immune system. MEDI4736 blocks these signals, countering the tumour’s immune-evading tactics.
MEDI4736 was accelerated into Phase III clinical development in non-small cell lung cancer and head and neck cancer. The OCEANS clinical development programme will evaluate MEDI4736 as monotherapy and in combination with a CTLA-4 (tremelimumab) in lung cancer, across the spectrum of the disease. In head and neck cancer, MEDI4736 is being investigated both as monotherapy and in combination with tremelimumab, looking at patients with different PD-L1 expression status who have failed on chemotherapy.
About tremelimumab
Tremelimumab is a fully human monoclonal IgG2 antibody, which stimulates the immune system to destroy cancer cells through binding to the protein CTLA-4, expressed on the surface of activated T-lymphocytes.
Tremelimumab has been granted Orphan Drug Designation by the US FDA for the treatment of patients with malignant mesothelioma. It is also currently being studied in combination with AstraZeneca’s anti -PD-L1 investigational immunotherapy, MEDI4736, in tumour types including non-small cell lung cancer and head and neck cancer. It is also being studied in combination with Iressa (gefitinib) in EGFR mutated non-small cell lung cancer and with MEDI6469 (a murine OX40 agonist) in solid tumours.
