Implementation of non-animal botox test hindered for commercial reasons

Dramatic increase in animal experimentation over recent years,
due to botox testing

The IAVS has been protesting against the dramatic increase in animal experimentation over recent years, which has been driven largely by the testing of botox-type products. Positive news emerged in March 2012 when ‘Botox’ producer Allergan announced they had developed a non-animal alternative to the extremely severe mouse LD50 test, which they claim will eventually reduce their animal testing by around 95%.

However, the IAVS was dismayed to learn that other botulinum toxin producers in Ireland, such as Ipsen and Merz, would continue to perform animal LD50 tests, contradicting the spirit of laws supposed to ensure that an animal test shall not be permitted if a scientifically satisfactory non-animal method is available. This scandal is compounded by the fact that most of these products are for the sake of vanity. But, according to the Irish Medicines Board and the Department of Health, this situation arises because the new Allergan test is effectively that company’s trade secret and so they had the right to keep it confidential rather than having to openly share it with Ipsen and Merz. Relatively trivial commercial considerations are resulting in severe animal cruelty.

This turns the spotlight on Allergan’s ethics: why have they failed to reach commercial terms with their competitors to share their non-animal test? Our concerns were reported in the Irish Times.   Janet Kettles, Allergan’s ‘spin doctor’, claimed in a reply to the Irish Times that her company has published information about their new non-animal test in order to allow other botulinum toxin producers to develop similar assays. This gives the impression that the blame for this current situation lies mainly with the other botulinum producers. However, there may be more to this than meets the eye: Allergan has set conditions that appear to be dissuading other companies from using their data to develop replacements for their own harmful LD50 tests.

Given the acute animal welfare issues at stake, the IAVS urges the botulinum toxin industry to do the right thing and work constructively to end the severe and unnecessary animal testing of their products.

However, in a positive development, Ipsen has recently confirmed to the group GAIA, who are our European Coalition (ECEAE) colleagues in Belgium, that it intends to end animal testing of their botulinum toxin products ‘Azzalure’ and ‘Dysport’ by the end of 2014. We hope they fulfil this commitment. Ipsen’s replacement test appears to be being developed without input from Allergan’s data, which raises a serious question: how many animals might have been spared pain and death if these companies had managed to cooperate? The IAVS recommends that the EU should tighten up its requirements to use non-animal alternatives and put in place procedures to abolish unnecessary delays in the use of such cruelty-free tests.

Growing old disgracefully

THE COSMETIC USE OF BOTOX Summary of article in FRAME News Issue 57

Botulinum toxin, produced by Clostridium botulinum, is one of the most powerful poisons known. In 1989 the US Food and Drug Administration approved the use of BOTOX for the treatment of strabismus (squint) and blepharospasm (involuntary and uncontrollable, forcible closure of the eyelids). In 1987 an ophthalmologist noticed that patients treated for blepharospasm also showed shallower frown lines between their eyes.

The effect of botulinum toxin on facial wrinkles has caught the imagination of celebrities and its uptake has been fueled by the media hype arising around the promise of a semblance of youth. The toxin can also prevent the functioning of sweat glands, thus making it a treatment for excessive sweating. Underarm BOTOX injections were part of a package offered to the participants in the Oscar ceremony in 2002!

The paralytic action of BOTOX on wrinkles is temporary. It is necessary to receive a new injection every 3-4 months. There is therefore continuing demand from BOTOX users. Over the four years up to 2002, the use of BOTOX to treat facial wrinkles increased by 1500% in the United States. It is estimated that future sales could reach a figure of $1 billion per year by 2006.

The eagerness of some people to be injected with a highly potent toxin in order to turn their faces into expressionless masks would be simply risible were it not for the fact that the benefit of such a sop to vanity is obtained at an extremely high cost in terms of animal suffering.

Like other biological products, such as vaccines, the potency of botulinum toxin varies from batch to batch. Therefore each batch has to be tested and this consists of the classic LD50 test in which mice are injected with various doses of the toxin to see which dose will kill half of them. The testing of each batch requires at least 100 mice to be observed for 3-4 days. During this time, the animals experience diffuse muscular paralysis, impaired vision, and paralysis of the diaphragm leading to suffocation and death. This lethality test remains the gold standard used by all manufacturers to express the potency of their preparations.

It is a paradox that the public opposition to the testing of cosmetics has seemingly not been transferred to the testing of botulinum toxin for cosmetic use. However, information on this topic is lacking. An extensive search of news and internet sources did not retrieve a single article aimed at the general public.

There is no excuse for the fact that animals are being subjected to very severe procedures in order to permit the marketing of a product for cosmetic purposes. It is scandalous that this poor, universally criticised LD50 test is still being used. In an ideal world, a moratorium would be declared on the trivial, non-medical use of botulinum toxin, at least until such time it can be tested by humane methods. In reality commercial opportunism and individual vanity will undoubtedly prevail over ethics, especially if public pressure is lacking. This sad fact adds even more urgency to the pressing need for valid alternatives to the in vivo potency test.

The IAVS is producing a leaflet to highlight the cruelty behind Botox injections.
