Stimulus money will fund nicotine vaccine trial
A $10-million grant to Nabi Pharmaceuticals of Rockville, Md., from the National Institute on Drug Abuse will fund a Phase 3 clinical trial of a new vaccine designed to prevent relapses among smokers -- the final step before the vaccine can be approved for general use. It is the first large trial of an anti-smoking vaccine.
The vaccine, called NicVax, stimulates the production of antibodies that bind to nicotine in the bloodstream.
Some evidence suggests that the antibodies may persist for only six to 12 months, but that may be long enough to allow smokers to get through the extremely difficult first months of withdrawal.
