Merck joins companies ending chimp research

TRENTON, N.J. – Drugmaker Merck & Co. is joining two dozen other pharmaceutical companies and contract laboratories in committing to not use chimpanzees for research.

The growing trend could mean roughly 1,000 chimps in the U.S. used for research or warehoused for many years in laboratory cages could be “retired” to sanctuaries by around 2020.

That’s according to Kathleen Conlee of the Humane Society of the United States, which seven years ago began urging companies to phase out all chimp research.

The trend is driven by improved technology, animal alternatives and pressure from animal rights groups, the National Institutes of Health and Congress.

Last June, reacting to an Institute of Medicine study Congress had requested that concluded nearly all chimp research is unnecessary, the NIH announced it would retire and send about 90 percent of government-owned research chimps to the Chimp Haven sanctuary in Keithville, La. It’s now home to about 160 chimps, with nearly 60 more to arrive soon.

After several years, the NIH plans to decide whether the remaining chimps in government labs can also be moved to sanctuaries. Roughly 450 other chimps are owned by private labs that do research under contract for drugmakers and other companies.

“It’s been a long road in trying to end the use of chimpanzees in research, and we’re now at a turning point,” Conlee told the Associated Press on Thursday. “We’re going to keep on (advocating) until the chimpanzees in laboratories are all in sanctuaries.”

Merck spokeswoman Caroline Lappetito said the company, based in Whitehouse Station, N.J., decided late last year to stop research on chimpanzees and switch to alternative types of testing.

“The science has advanced, and we don’t really need it,” Lappetito said.

Merck, the world’s third-biggest drugmaker, is the largest to make the switch.

Companies that develop medicines and consumer products such as cosmetics have long used animals to test safety and effectiveness. In the case of experimental medicines, drugmakers must test on animals before the Food and Drug Administration will let them do the human testing needed for approval of a new therapy.

Nearly all animal experiments in the U.S. involve mice, rats and guinea pigs, although some are done on dogs and great apes, almost always chimpanzees.

Many companies previously said it was necessary to test medicines and vaccines on nonhuman primates because they needed an animal in which the anatomy and disease course were very similar to that in humans.

That thinking changed as technology allowed researchers to do initial testing via computer simulations, in bacteria or cells, and in animals as small as fish.
