Primate poposal by Netherlands government ‘will severely limit progress on biomedical research’.

EARA has responded to a call by the Dutch Science Minister for the Biomedical Primate Research Centre (BPRC), in the Netherlands, an EARA member, to draw up a proposal, by the beginning of next year, to reduce the number of experiments with no-human primates (NHP) by up to 40%.

Ahead of a debate, which took place in the Netherlands House of Representatives earlier this month, EARA wrote to Ingrid van Engelshoven, Minister of Education, Culture and Science and Carola Schouten, Minister of Agriculture, Nature and Food Quality, urging them not to set an artificial limit on the number of NHP used in research.

The letter, written by EARA, said that any reduction was “highly likely to severely limit the progress that can be made in both fundamental research and the development of innovative medicines and treatments for life-threatening diseases and infectious disease control”.

Currently the main areas of primate study are infectious diseases, neuroscience and fertility and foetal research. Primates are an important model for the development of vaccines and treatments for HIV/AIDS, Ebola, Zika and malaria and for investigations into treatments for conditions ranging from Alzheimer’s disease to Schizophrenia. They are also used in safety testing for new medicines and vaccines.

Presently, the use of animals in research, especially NHP, is highly regulated and under EU Directive 2010/63 no animal can be used if there is any practical alternative method. The Scientific Committee on Health Environmental and Emerging Risks (SCHEER) confirmed in its 2017 updated opinion, the continued need and benefit of the use of NHP in research, and stated, “the current state of knowledge does not permit to propose a timetable for phasing-out the use of NHP in Europe”.

The letter also explains that research primates continue to be used in relatively small numbers (currently 0.05% of all research animal used in the EU) but they have made an extremely important contribution to many significant medical advances, for example the polio vaccine, life support systems for premature babies and deep brain stimulation for Parkinson’s Disease.
EARA Executive Director, Kirk Leech, said: “BPRC carries out essential research on diseases such as AIDS, malaria and MS and we are working together with it to ensure its message is heard and understood by the Dutch government.”

The letter went on to say: “The research community is fully committed to the 3Rs principles: replacement; reduction; and refinement and we support the minister’s call for greater sharing of data in research with laboratory animals, including the publishing negative results, which is in line with the sector’s own desire for greater transparency and openness.

“The sector actively seeks opportunities to replace animal studies with alternative methods, to design studies that enable us to reduce the number of animals needed to obtain a scientifically valid result and to refine studies to minimise pain and distress to the animals involved. This has already led to a significant reduction in the numbers of animals used, of all species, in recent years.”

Germany sees 7% rise in animal research procedures in 2016

This article first appeared in Speaking of Research 06/02/18

Germany’s Federal Ministry of Food and Agriculture (Bundesministerium für Ernährung und Landwirtschaft) has produced its 2016 annual statistics on animal research procedures for Germany. These statistics have seen some big changes from previous years and we will attempt to show comparisons according to the different methodologies used. Germany produces two sets of data as part of the Animal Protection Act.

  • 7(2) – procedures on animals
  • 4(3) – animals killed solely for tissues or organs without any prior procedures

A mouse procedure

Historically, Germany has used data from animals used under both §7(2) and §4(3) of the Animal Protection Act to create a dataset of animals used in research. This dataset was broken down by varying categories including use, severity, genetic status and more. This year, while the old totals can be seen, the main datasets are numbers of procedures on animals, excluding animals killed for tissues or organs (under §4(3)). This newer methodology puts Germany in line with the EU reporting requirements for animals in research – allowing for easier comparisons between countries.

In 2016, Germany reported 2,189,261 procedures on animals, up 7.1% from 2015. The number of animals is slightly lower at 2,131,448 (due to some animals being used in more than one procedure during 2016). Continue reading

Animal research – a debate between a primate researcher and an opponent

This article was first printed in Spiegel on 28 December 2017 and is reprinted here in the English translation.

A moderated debate between Prof. Stefan Treue, (pictured below) animal physiologist, neuroscientist and director of the German Primate Center – Leibniz Institute for Primate Research in Göttingen and Jörg Luy, philosopher, veterinarian and animal ethicist at the Research and Advisory Institute for Applied Ethics and Animal Welfare Instet in Berlin.

Thousands of monkeys are kept in Germany alone for animal experiments. Is that justifiable?

Spiegel Moderation: Ann-Katrin Müller and Philip Bethge.

SPIEGEL: Mr. Lucy, researchers in Japan have recently transplanted cynomolgus nerve cells that had previously been bred in the laboratory. The monkeys were suffering from Parkinson’s disease. After the transplant they could move better again.

Luy: That sounds great, but it’s not, because Parkinson’s disease was artificially caused in the animals. If you want my short ethical assessment: unacceptable.

SPIEGEL: Would you stick to this assessment if a close relative of yours had Parkinson’s and would benefit from the monkey-engrafted transplant?

Luy: Unfortunately, we have a Parkinson’s case in the family. But that does not change my assessment. It is unlikely that the Javan monkeys have voluntarily consented to this transplantation experiment, let alone the procedure that artificially causes Parkinson’s disease. Therefore, the experiment is ethically not allowed. One would never make such attempts on people.

SPIEGEL: Does not the healing of a disease have a higher ethical value?

Luy: That’s a very dangerous thought. If you continue to spin, you will end up with human experiments. They might also help patients. If we even weigh process and utility, then the crucial point is: is it worth it for the test object to participate in the experiment? Is it a fair deal?

SPIEGEL: Mr. Treue, in Germany about 3,000 primates are currently being kept for animal research, especially crab ape and rhesus monkeys, and there are tens of thousands worldwide. Socially, experiments on primates are apparently considered justifiable throughout the world. Also from you?

Treue: No one is happy about animal testing, but on certain research questions they are necessary and justifiable. Exactly this is also the legal situation: There is no general prohibition of animal experiments, but a process of consideration. In other words, experiments on animals are prohibited unless a long list of conditions are met. Continue reading

Hundreds of scientists sign letter supporting primates in neuroscience

Over 400 primate and neuroscience researchers signed a letter supporting the use of non-human primates in neuroscience, which was published in the Guardian today. Coordinated by Understanding Animal Research (UAR), the letter emphasises the key role that primate research has played and continues to play in vital neuroscience research. EARA signed the letter alongside 20 other institutions, as well as reaching out to our networks in Europe to gain further support. The letter can still be signed via this link.

The letter is a timely response to mounting pressure by animal rights groups against the use of non-human primates in biomedical research. Last week, the Independent published a letter coordinated by Cruelty Free International denouncing primate research, and earlier this year, the Australian Senate rejected a proposed ban on importing non-human primates for scientific research. The UAR letter is the latest in a series of efforts from the scientific community to underline the importance of this type of research, including the Foundation of Biomedical Research’s White Paper on primate research and the National Institutes of Health workshop held last week.

Kirk Leech, EARA’s Executive Director, said:

“NHP research continues to underpin our understanding of brain processes and debilitating brain conditions and allows assessing the efficiency and safety of a candidate drug. Animal research, in particular with regard to primates, is highly regulated on legal and ethical grounds as enshrined in European Directive 2010/63.

“Out of the 4.14 million procedures completed in the UK in 2015, only 0.16% were performed on primates, which accounts for 3,600 procedures. This number does not even represent the real number of primates used in procedures, since some animals undergo several procedures to reduce the use of animals. Out of this small proportion, only 0.8% were classified as severe. 

“Accurate and contrasted information is necessary to ensure a balanced dialogue that considers all risks and opportunities involved, especially in such a contentious issue as using primates in neuroscience research. We encourage and support the scientific community in the quest to provide timely and truthful information to promote scientific research.”

Full text of the letter:

Nonhuman primates have long played a key role in life-changing medical advances. A recent white paper by nine scientific societies in the US produced a list of 50 medical advances from the last 50 years made possible through studies on nonhuman primates. These included: treatments for leprosy, HIV and Parkinson’s; the MMR and hepatitis B vaccines; and earlier diagnosis and better treatment for polycystic ovary syndrome and breast cancer.

The biological similarities between humans and other primates mean that they are sometimes the only effective model for complex neurodegenerative diseases such as Parkinson’s. More than 10 million people suffer from Parkinson’s worldwide, and a recent study estimated that one in three people born in 2015 will develop dementia in their lifetime. Primate research offers treatments, and hope for future treatments, to patients and their families. Already over 200,000 Parkinson’s patients have had their life dramatically improved thanks to deep brain stimulation surgery, which reduces the tremors of sufferers. This treatment was developed from research carried out in a few hundred monkeys in the 1980s and 1990s.

Given that primates are intelligent and sensitive animals, such research requires a higher level of ethical justification. The scientific community continues to work together to minimise the suffering of primates wherever possible. We welcome the worldwide effort to replace, refine and reduce the use of primates in research.

We, the undersigned, believe that if we are to effectively combat the scourge of neurodegenerative and other crippling diseases, we will require the careful and considered use of nonhuman primates. Stringent regulations across the developed world exist to ensure that primates are only used where there is no other available model – be that the use of a mouse or a non-animal alternative – and to protect the wellbeing of those animals still required. The use of primates is not undertaken lightly. However, while not all primate research results in a new treatment, it nonetheless plays a role in developing both the basic and applied knowledge that is crucial for medical advances.

Studying the Zika virus in rhesus macaques

The 2016 Olympic Games are due to begin in Rio de Janeiro this weekend. In the lead-up to this year’s Games, the Zika virus has never been far from the headlines. A number of top golfers and basketball players have decided to pull out and other athletes have also expressed their concerns, despite the risk to anyone who is not pregnant being minimal. As it is not currently mosquito season in Brazil, experts say the Olympics will not accelerate the spread of the virus.

It is thought the epidemic has reached its peak in Latin America and will slowly burn out over the next few years. Still, there have been over 60,000 confirmed cases of the Zika virus in Brazil since the outbreak began in early 2015 and the virus has reached Europe, with the first baby with Zika-related microcephaly born in Spain. Mosquitoes in Florida have now also been seen to transmit the virus, and the Centers for Disease Control and Prevention (CDC) in the US have issued a travel warning for Florida.

The Zika virus remains a prominent public health concern and a priority for the biosciences. In March, EARA spoke to Dr Koen van Rompay, who helped to develop and test the anti-viral drug tenofovir, which is currently the most frequently used HIV drug in the world. We interviewed him on the day before he and his team at the California National Primate Research Center (CNPRC) infected two female rhesus macaques with Zika virus to understand how the disease progresses. We asked him about his current study on the Zika virus, why he uses primate models in his work and how he responds to critics of animal research. Continue reading

Australian Senate rejects bill to ban the importation of non-human primates

Last week, the Australian Senate released their report in response to a proposed law amendment to ban the importation of non-human primates to Australia for the purposes of scientific research. After receiving submissions opposing the bill from scientific organisations and individuals from around the globe, including EARA, the Senate has decided not to pass the bill. Continue reading

Babies’ sight restored thanks to new surgical technique first tested in animals

Thanks to an innovative new surgery first tested in rabbits and macaques, twelve babies born with cataracts have regained their sight.

The current way of treating cataracts is to surgically remove the clouded-over lenses and to replace them with artificial ones. But Kang Zhang and his colleagues at the Shiley Eye Institute at the University of California in San Diego found that stem cells around the lens can regrow healthy lenses if left undamaged by the surgery.
