Drug disapproval COULD US drug regulators be feeling the heat of government scrutiny? On 13 June, federal health advisers unanimously declined to approve a new weightloss drug because of concerns that it might cause suicidal thoughts and other psychiatric problems. In studies presented to a panel
Worm turned PREVENTION is proving better than cure yet again. The parasitic Guinea worm – which grows up to 60 centimetres long and is usually extracted painfully by hand – faces eradication by 2009. And that’s without the aid of drugs. Instead, millions of Africans broke the cycle of infection by following a global prevention campaign led by the Carter Center in Atlanta, Georgia. Guinea worms mainly infect people who drink water

contaminated with fleas that carry the worm larvae. These grow in the body, but must re-emerge to reach water and complete their life cycle by producing more larvae. The eradication programme, started in 1980, involves villagebased surveillance to prevent the worm spreading. In Uganda, for example, elderly villagers serve as “pond caretakers”, preventing people with emerging worms from entering the water, and fetching water for them instead. “It’s a really great example of old-fashioned public health measures without the usual burden of money and drugs,” says Michele Barry at Yale University –IT, we have a problem– School of Medicine in New Haven,

Clifford Rosen, who chaired the panel, says that while the FDA always presents panels with evidence on drug safety, the amount for Accomplia was “a bit unusual”. “I think they’re being very cautious right now.” The FDA says the amount of evidence considered was set many years ago and not influenced by the PDUFA. The FDA is expected to make a final decision by 27 July.
