New study shows researchers’ reluctance to abandon animal research despite decades of failure

This new study by Pandora Pound and Rebecca Ram from Safer Medicines, published in BMJ Open Science, analyses the opinions of scientists who conduct animal studies of stroke. At present there is only one drug available for patients with acute stroke, a ‘clot buster’ called Alteplase (and this drug was not directly dependent upon animal research for its development). Alteplase can only be given to a minority of stroke patients, half of whom will not benefit from it, so there is an urgent need for effective treatments in this area. Given the failure to develop treatments for acute stroke despite decades of animal research in this field, the study aimed to explore scientists’ views about the way forward.

We found that scientists conducting animal studies of stroke agreed that the field was in crisis, and many robustly criticised the science in this area. When it came to identifying the causes of this crisis, most scientists focused on the poor quality of animal studies. Similarly, when it came to solutions, most proposed improving the quality of animal studies in the hope that this would ultimately translate into benefits for stroke patients. A small number of researchers proposed using human in vitro methods alongside animal studies and one proposed using human focused methods instead of animal studies. Although there is evidence then, that a minority of scientists are beginning to consider human focused approaches, our study indicates a strong resistance to relinquishing the use of animal models in stroke research, despite decades of their failure to produce any benefits for stroke patients.

New paper discusses  in silico New Approach Methodologies (NAMs) and increasing use of ‘big data’ to advance human relevant research

A new paper by Safer Medicines scientific consultant Rebecca Ram, Dr. Domenico Gadaleta of the Mario Negri Institute, Italy and Dr. Tim Allen of the MRC Toxicology Unit, Cambridge discusses the progress of in-silico methods in New Approach Methodologies (NAMs) as well as the increasing need for use of ‘big data’ and artificial intelligence (AI) […]

World Animal Free Research Day

One of our partner charities in the Alliance for Human Relevant Science is Animal Free Research UK. They have initiated an annual World Animal Free Research Day on the anniversary of their founding, 27th May. Our goals are very complementary: Animal Free Research UK’s vision is “To create a world where human diseases are cured faster without animal suffering”, while […]
