Drug trial breakthrough shows that Ebola is ‘no longer incurable’

EARA Executive Director, Kirk Leech, looks at the remarkable progress in biomedical research in the search for a cure for Ebola virus which has devastated parts of central Africa in the last year.

This week, marking the first anniversary of the most recent Ebola outbreak, scientists running a clinical trial of new drugs in the Democratic Republic of the Congo (DRC) have announced a dramatic increase in survival rates.

For countries, such as the DRC, Liberia, Guinea, and Sierra Leone, Ebola is a serious health emergency. They are among the poorest countries in the world, only recently emerging from years of civil war and unrest that has left basic health infrastructures severely damaged or ruined. Living conditions are often restricted and unclean, water supplies are limited, medical treatment is scarce, and trust in officialdom, pretty much non-existent.

Massive underdevelopment and the attendant problem of political dysfunction have created a situation in which a virus like Ebola can flourish. Since 2014 a total of 28,616 cases of Ebola and 11,310 deaths were reported in Guinea, Liberia, and Sierra Leone. This is what is driving research into finding a way to halt the spread of the disease

Now, thanks in part to research involving mice and non-human primates the sponsors of the current clinical trial in DRC have announced a real breakthrough. While an experimental vaccine that was proven to be effective in monkeys had previously been shown to shield people from catching Ebola, this new development marks a first for people who have already been infected.

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

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.

The Research Animals That Have Made A Difference

Over the last 40 years, every Nobel Prize in physiology or medicine but one has depended on work using animals. From modern vaccines that protect us against polio, TB and meningitis, to the development of Tamoxifen that has led to a 30% fall in death rates from breast cancer, the role of research animals cannot be underestimated.
