Previous phase 1 and 2 clinical trials have been conducted into Tebentafusp, a new anti-tumour immune response drug for patients with metastatic melanoma. The results from Immunocore and the University of Oxford, found that this first-of-its-kind treatment showed great promise in helping the immune system fight off melanoma cancers of both the eye and skin. The phase 3 clinical trial for this drug is the first for an affinity optimised T-cell receptor drug, making it the first of its kind.
Today, Immunocore the company behind the drug have announced trial results showing tebentafusp works better for patients with untreated metastatic uveal melanoma, when compared to other treatment choices.
A positive survival benefit for tebentafusp represents a major step towards bringing a potential new treatment for cancer patients with a high unmet need. If approved, it would be the first new therapy to improve the overall survival in 40 years and to be specifically used in the treatment of metastatic uveal melanoma, a disease with poor survival where new therapies are urgently needed
- Bahija Jallal, CEO of Immunocore
Tebentafusp comes out of clinical trials led by Prof Mark Middleton (Department of Oncology). Now, we see the potential for this drug coming into the clinic, subject to regulatory approval, as early as next year.
It is very exciting that our observations in the first trial of tebentafusp, that it could make some uveal melanomas shrink, have now been borne out in larger studies. There’s still a way to go but there is every hope that this will prove an option for the treatment of this difficult cancer quite soon,
- Prof Mark Middleton, University of Oxford and the National Institute for Health Research Oxford Biomedical Research Centre
Uveal melanoma is a rare and aggressive form of cancer that affects the eye, and typically has a poor prognosis and has no accepted optimal treatment and management. After the cancer metastases, 50% of patients have life expectancy of less than a year. Tebentafusp has the potential to be the first new therapy to improve the life expectancy of patients in over 40 years.

The National Institute for Health Research (NIHR) Oxford Biomedical Research Centre (BRC) is based at the Oxford University Hospitals NHS Foundation Trust and run in partnership with the University of Oxford.
The NIHR is the nation's largest funder of health and care research. The NIHR:
- Funds, supports and delivers high quality research that benefits the NHS, public health and social care
- Engages and involves patients, carers and the public in order to improve the reach, quality and impact of research
- Attracts, trains and supports the best researchers to tackle the complex health and care challenges of the future
- Invests in world-class infrastructure and a skilled delivery workforce to translate discoveries into improved treatments and services
- Partners with other public funders, charities and industry to maximise the value of research to patients and the economy
The NIHR was established in 2006 to improve the health and wealth of the nation through research, and is funded by the Department of Health and Social Care. In addition to its national role, the NIHR supports applied health research for the direct and primary benefit of people in low- and middle-income countries, using UK aid from the UK government.
This work uses data provided by patients and collected by the NHS as part of their care and support and would not have been possible without access to this data. The NIHR recognises and values the role of patient data, securely accessed and stored, both in underpinning and leading to improvements in research and care. www.nihr.ac.uk/patientdata
