Pulling out of research into Alzheimer’s

Drug company Pfizer has announced it is pulling out of research into drugs to treat Alzheimer’s disease. The US-based pharmaceutical giant said it would be ending its neuroscience discovery programmes following a review, and 300 jobs would be lost. The Alzheimer’s Society called the news “disappointing” and a “heavy blow” to those living with dementia. Companies should be encouraged to invest in research into neuroscience, Alzheimer’s Research UK said. The move means Pfizer will also stop looking for treatments for Parkinson’s disease, but the company said it planned to create a new fund dedicated to neuroscience research in the future. A statement from the company said: “We have made the decision to end our neuroscience discovery and early development efforts and re-allocate funding to those areas where we have strong scientific leadership and that will allow us to provide the greatest impact for patients.” Complex brain Prof Tara Spire-Jones, a neuroscientist at Edinburgh University, told the Today programme on BBC Radio 4 that despite the decision, there was still a lot of hope. “Not all pharmaceutical companies are pulling out and there are over 100 clinical trials at the moment. “There is a lot going on in the basic science - we need to understand the complexity of the brain.” She said Pfizer’s decision was understandable because of the failure rate of clinical trials. “More than 99% of trials for Alzheimer’s drugs have failed in past 15 years. “So companies are justifiably cautious, but we are making great advances on the scientific front.” Prof Spire-Jones added: “We’ve learned from these failures of trials that we need to take a step back and understand brain changes. “At the moment we don’t fully understand how memory and thinking work fully in a healthy brain.” Pharmaceutical companies including Novartis, Janssen, Biogen, Abbvie and Eli Lilly are still developing medicines to treat Alzheimer’s disease and a spokesman for the ABPI (Association of the British Pharmaceutical Industry) said they continued “to make progress in unravelling the complexities of the brain and identifying the underpinnings of the disease”. Could drugs delay the diseases of ageing? What are the secrets of the superagers? Dr James Pickett, head of research at Alzheimer’s Society, said: “Of course it’s disappointing to hear that Pfizer, one of the world’s leading pharmaceutical companies, will be terminating their research efforts in neuroscience, including Alzheimer’s disease drug discovery.
