Press release: First patient receives potential new treatment for wet age-related macular degeneration in London Project to Cure Blindness.London Monday 28 September: A pioneering trial of a new treatment derived from stem cells for people with ‘wet’ age-related macular degeneration (AMD) has commenced at Moorfields Eye Hospital following a successful operation on a patient.
This first operation is a major milestone in the London Project to Cure Blindness, which was established 10 years ago with the aim of curing vision loss in patients with wet AMD, and is the result of a partnership between the hospital, the UCL Institute of Ophthalmology, and the National Institute for Health Research (NIHR). Pfizer Inc. joined the partnership [in 2009] with the goal of helping to turn the original idea into a potential therapy.
The trial is investigating the safety and efficacy of transplanting eye cells (retinal pigment epithelium) derived from stem cells to treat people with sudden severe visual loss from wet AMD. These cells are used to replace those at the back of the eye that are diseased in AMD. This is done using a specially engineered patch inserted behind the retina in an operation lasting one to two hours.
The first surgery was successfully performed on a patient last month and there have been no complications to date. The patient wishes to remain anonymous, but the team hope to determine her outcome in terms of initial visual recovery by early December (2015).
“There is real potential that people with wet age-related macular degeneration will benefit in the future from transplantation of these cells,” says retinal surgeon Professor Lyndon Da Cruz from Moorfields Eye Hospital, who is performing the operations and is co-leading the London Project.
The trial will recruit 10 patients in total over a period of 18 months. Each patient will be followed for a year to assess the safety and stability of the cells and whether there is an effect in restoring vision.Professor Pete Coffey of the UCL Institute of Ophthalmology, who is also co-leading the London Project, said: “We are tremendously pleased to have
reached this stage in the research for a new therapeutic approach. Although we recognise this clinical trial focuses on a small group of AMD patients who have experienced sudden severe visual loss, we hope that many patients may benefit in the future.”
Professor Sir Peng Tee Khaw, Director of the National Institute for Health Research (NIHR) Biomedical Research Centre based at Moorfields Eye Hospital and the UCL Institute of Ophthalmology, added: “We are delighted to be the site for this very exciting new clinical trial in stem cell therapy, which has the potential to give hope and make such a difference to the lives of people with blinding retinal conditions,”.
Professor Philip J Luthert, Director of the UCL Institute of Ophthalmology, said: “The trial has shown the power of collaboration between the University, Moorfields Eye Hospital NHS Foundation Trust and Pfizer in establishing a new treatment paradigm for AMD. The London Project has been funded by large philanthropic donations, government funding agencies, charities, the NIHR and many private donors over the past few years, and Pfizer’s commitment has been vital in moving this project forward.”
Dr Berkeley Phillips, UK Medical Director, Pfizer Ltd concluded: “At Pfizer we believe that great science comes through collaboration; no one person has all the answers and together, we can achieve more and move faster. Stem cell-derived therapy was only a theory until recent years, and to be part of a project that is applying the latest scientific breakthroughs to help restore patients’ eyesight is truly rewarding”The London Project to Cure Blindness would like to thank:

About ‘wet’ AMD Macular degeneration accounts for almost 50% of all visual impairment in the developed world. It usually affects people over 50 years of age and is known as age-related macular degeneration (AMD). It affects around 25% of over 60s in the UK, a figure that is set to increase. In people with AMD, the central (reading) vision is affected and the surrounding vision remains normal. There are two types of AMD, wet and dry. Wet AMD is generally caused by abnormal blood vessels that leak fluid or blood into the region of the macula, in the center of the retina. Wet macular degeneration almost always begins as dry macular degeneration. Dry AMD is the most common type of macular degeneration and affects 90% of the people who have the condition. In the dry form, there is a breakdown or thinning of the layer of retinal pigment epithelial cells (RPE) in the macula. These RPE cells support the light sensitive photoreceptor cells that are so critical to vision. There is no treatment at present for dry AMD. NIHR Biomedical Research Centre at Moorfields Eye Hospital NHS Foundation Trust and UCL Institute of Ophthalmology was established in April 2007 and awarded a second five-year term by the NIHR from April 2012. Its purpose is to conduct 'translational research' that is designed to take advances in basic medical research from the laboratory to the clinic, enabling patients to benefit more quickly from new scientific breakthroughs. Our centre is currently one of 11 biomedical research centres that were awarded in 2012 to NHS/university partnerships with an outstanding international reputation for medical research and expertise, and experience of translating that research into the clinical setting.

About the NIHR The National Institute for Health Research (NIHR) is funded by the Department of Health to improve the health and wealth of the nation through research. Since its establishment in April 2006, the NIHR has transformed research in the NHS. It has increased the volume of applied health research for the benefit of patients and the public, driven faster translation of basic science discoveries into tangible benefits for patients and the economy, and developed and supported the people who conduct and contribute to applied health research. The NIHR plays a key role in the Government’s strategy for economic growth, attracting investment by the life-sciences industries through its world-class infrastructure for health research. Together, the NIHR people, programmes, centres of excellence, and systems represent the most integrated health research system in the world.
