Elan, Wyeth report success in Alzheimer drug trial
MADISON, N.J. and DUBLIN, Ireland Elan and Wyeth have announced preliminary findings from a 18-month Phase 2 study of their drug bapineuzumab in patients with mild to moderate Alzheimer’s disease, and say the findings support plans to take the drug to the large-scale trials stage, according to published reports.
The 18-month trial saw statistically significant and clinically meaningful benefits for patients not carrying a gene known as “ApoE4,” which apparently accounts for 40 percent to 70 percent of Alzheimer’s sufferers.
According to Elan, for non-carriers of ApoE4, the study’s preliminary results showed a smaller loss of brain volume among treated patients than for placebo patients. Loss of brain volume is associated with the onset of Alzheimer’s.
The bapineuzumab treatment is an antibody designed to clear amyloid from the brain, which is seen as the most likely path to success for fighting Alzheimer’s. Amyloids are protein deposits found in the brains of Alzheimer’s victims.
Major drug companies agree to six-month moratorium on DTC ads
WASHINGTON Under pressure from some of the top members of the House of Representatives, top drug companies, including Merck, Johnson & Johnson and Pfizer, are agreeing on a six-month moratorium on advertising new drugs to consumers and will limit how doctors are used in their ads, according to reports.
The changes were unveiled in letters the manufacturers sent the House Energy and Commerce Committee responding to a request from committee chairman John Dingell, D-Mich., and Rep. Bart Stupak, D-Mich., who head the committee’s oversight and investigations panel.
Dingell and Stupak had wanted the companies to impose a two-year voluntary moratorium on advertising of new prescription drugs to consumers – and possibly even longer in the case of drugs for which not all studies have been completed. The lawmakers also asked the drug companies to limit the use of doctors in their advertising and agree to “black box” warnings on ads if the Food and Drug Administration requested them.
In the letters, executives of J&J, Merck, Merck/Schering-Plough and Pfizer agreed to take several steps, while the Pharmaceutical Research and Manufacturers of America agreed to hold further meetings with the committee. The companies will start following the American Medical Association’s guidelines about using actors to portray doctors, and at least one marketer, J&J, said it would not use doctors in ads to discuss the benefits of a drug.
The drug companies said in their letters that the six-month moratorium formalized industry practice, which is to educate doctors before moving to consumer communications. “We drugs [that] requires that our operating companies spend at least six months after approval have adopted internal guiding practices on direct-to-consumer advertising for prescription of a new medicine educating health professionals before commencing a direct-to-consumer advertising campaign,” wrote William Weldon, chairman and chief executive officer of J&J. He added that the company “does not believe a particular fixed period of time for an advertising moratorium is appropriate in all circumstances.”
Dingell and Stupak said they were pleased with the response, but wanted the drug companies to go further, with a two-year limit.
