A BATTLE by animal rights activists to save 14 chimpanzees from science and medical testing may well sound the death knell for all US medical experiments on the primates.
Rights and ethics groups led by the Physicians Committee for Responsible Medicine (PCRM) have seized on the case, which pits them against a powerful federal research agency, the National Institutes of Health (NIH), and revives debate the usefulness, as well as the ethics, of experimenting on humankind's closest living relatives.
Dallas doctor John Pippin, a PCRM senior adviser, said the NIH "acted unlawfully" in June and July 2010 when it transferred four female and 10 male chimps to a controversial laboratory in San Antonio, Texas, for use in invasive experiments.
Pippin and several other experts who are members of the non-profit PCRM filed a legal petition seeking immediate return of the chimps to their home at a non-research government facility in Alamogordo, New Mexico, where they lived with 186 other chimpanzees.
..Moving the animals "was arbitrary, capricious, an abuse of agency discretion, and in violation of the federal Administrative Procedure Act", Pippin told AFP in an interview.
The animals sent to the Southwest National Primate Research Center (SNPRC) are "old and sick," Pippin said. The research, he added, "is scientifically useless and also horribly inhumane".
The experts cite Rosie, a 29-year-old chimpanzee who was chemically immobilised 99 times by researchers in years of invasive experiments, as one of the 14 brought out of retirement and sent to Texas.
Chimpanzees have been used in research for decades, but many scientists have dismissed their usefulness in AIDS and malaria research, and their effectiveness in studies of hepatitis and other infections is in dispute.
After the European Union's 27 member states banned primate experiments last year, the US is now the only industrialised nation which has not done likewise.
Contacted by AFP, the NIH had yet to make a comment on the case as of late on Friday - but there are signs it is reacting to mounting pressure over the chimpanzees.
Activist groups and the then-governor of New Mexico, Bill Richardson, managed to convince NIH to suspend transfer of other chimpanzees from Alamogordo, according to Pippin.
NIH has agreed to await the findings of the independent Institute of Medicine, which has now launched what NIH acknowledged is "in-depth analysis to reassess the scientific need for the continued use of chimpanzees to accelerate biomedical discoveries".
It could take up to two years for the findings of the institute's study to emerge.
The PCRM notes the institute that oversees the Texas primate centre endorses primate studies involving "bioterrorism agents and other deadly pathogens" including Ebola virus and anthrax, in addition to work on AIDS and other infections.
Pippin and others insist the chimp research has no scientific value.
"The proof is that we don't have any hepatitis C vaccine, we don't have any AIDS vaccine, malaria vaccine," he said.
"We don't have an effective treatment for any of these diseases that have been studied on chimpanzees for decades."
But some researchers insist the experiments are vital, and vigorously defend lab research on animals such as mice and chimpanzees to advance medicine.
"We've made a lot of progress in research on hepatitis using chimpanzees," SNPRC director John VandeBerg told the Washington Post this week.
VandeBerg acknowledged that other developed nations no longer use chimpanzees for medical experiments, but stressed European societies "made a decision that was driven by animal rights advocates," and that European scientists still come to the US to do research on primates.
"They need chimpanzees just as badly as we do," he said.
About 1000 chimpanzees remain in US laboratories, including 500 at NIH facilities. Their number has decreased in recent years as breeding chimpanzees in captivity is now banned and importing them is illegal.
