TRENTON, N.J. -- A closely watched experimental Alzheimer's treatment has failed to slow the disease in one late-stage study, a big disappointment for doctors and patients but not the end of the road for the drug.
Pfizer Inc. said Monday that it will continue to study its effect on a different group of patients.
Pfizer, which is testing bapineuzumab with partner Johnson & Johnson, said the injected drug didn't slow mental or functional decline in patients with mild or moderate Alzheimer's disease. The study included about 1,100 patients who carry a gene called ApoE4, which gives people a higher risk of developing the memory-robbing disorder.
