PARIS | BY MATTHIAS BLAMONT
One person has been left brain dead and five others have been hospitalized after taking part in a clinical trial in France of an experimental drug made by Portuguese drug company Bial, French Health Minister Marisol Touraine said on Friday.
In total, 90 people have taken part in the trial, taking some dosage of the drug aimed at tackling mood and anxiety issues, as well as movement coordination disorders linked to neurological issues, Touraine said.
The six men aged 28 to 49 had been in good health until taking the oral medication at the Biotrial private facility that specializes in clinical trials, she said.
“This is unprecedented,” Touraine told a news conference after meeting volunteers and their families in Rennes, western France. “We’ll do everything to understand what happened.”
Prosecutors have opened an investigation into the case.
The six men started taking the drug on Jan. 7. The brain-dead volunteer was admitted to hospital on Monday, the minister said.
For three of the five others – who went in on Wednesday and Thursday – there are fears of irreversible handicap, doctor Gilles Edan said, though he still hoped that would not be the case. One of the six had no symptoms but was being carefully monitored, he said.
Testing had already been carried out on animals, including chimpanzees, starting in July, Touraine said.
All trials on the drug have now been suspended and all volunteers who have taken part in the trial are being called back, the health ministry added.
The medicine involved is a so-called FAAH inhibitor that works by targeting the body’s endocannabinoid system, which is also responsible for the human response to cannabis.
Bial said in a statement it was committed to ensuring the wellbeing of test participants and was working with authorities to discover the cause of the injuries, adding that the clinical trial have been approved by French regulators.
The company said five people, rather than six, had been hospitalized, including one left brain dead, without explaining the discrepancy with the official French figures.
Cases of early-stage clinical trials going badly wrong are rare but not unheard of. In 2006, six healthy volunteers given an experimental drug in London ended up in intensive care. One was described as looking like “the elephant man” after his head ballooned. Another lost his fingertips and toes.
In the initial Phase I stage of clinical testing, a drug is given to healthy volunteers to see how it is handled by the body and what is the right dose to give to patients.
“Undertaking Phase 1 studies is highly specialist work,” said Daniel Hawcutt, a lecturer in clinical pharmacology at Britain’s University of Liverpool.
Medicines then go into larger Phase II and Phase III trials to assess their effectiveness and safety before they are finally approved for sale.
Europe has strict regulations governing the conduct of clinical trials, with Phase I tests subject to particular scrutiny. But Ben Whalley, a professor of neuropharmacology at the University of Reading, said these could only minimize risks, not abolish them.
“There is an inherent risk in exposing people to any new compound,” he said.
The 2006 London trial led to the collapse of Germany’s TeGenero, the company developing a medicine known as TGN1412. The drug has since gone back into tests for rheumatoid arthritis and is showing promise when given at a fraction of the original dose.

Fransa’da yapılan bir ilaç deneyi faciayla bitti. Deneye katılanlardan 6’sı da yoğun bakıma kaldırıldı. Birinin beyin ölümü gerçekleşti. Olay, deneylerin güvenliği hakkında soru işaretleri yarattı.
Fransa’nın Rennes kentinde yapılan bir “ilaç deneyi” sonucu bir kişinin beyin ölümü gerçekleşirken, 5 kişi yoğun bakıma kaldırıldı. Fransa sağlık Bakanlığı, gönüllü olan 6 kişinin hapı almadan önce oldukça “sağlıklı” olduğunu belirtirken, ilacın Avrupa’da bir laboratuvarda üretildiğini açıkladı. Bakanlık ayrıca ilacın özel bir tesiste klinik deney yürüten uzmanlar tarafından geliştirildiğini vurguladı. Paris savcılığı konu hakkında soruşturma başlattı.
Ağrı kesici hapıymış
Sağlık Bakanlığı, Biotrial isimli ilaç firması tarafından denemeleri yapılan ilacın ne tür bir tedavi için kullanılacağına dair somut bir bilgi paylaşılmadı. Ancak, Fransız basınında yer alan haberlerde, ilacın içeriğinde kenevir bulunduğu ve Ağrı kesici olarak kullanılmak üzere denendiği ifade edildi. İlacın deneme çalışmaları da durduruldu.
