Nabi NicVax Phase II data

This article was originally published in Pharmaceutical Approvals Monthly

Executive Summary

Nabi's nicotine conjugate vaccine NicVax yielded a 33% quit rate in smokers in a Phase II study, compared to 9% for placebo, the company announces Sept. 28. The vaccine was tested at three doses, with the highest dose (200 mcg) producing the 33% cessation rate. "In addition, results showed a substantial reduction in average cigarette consumption in smokers who received the highest dose…versus lower doses or placebo," the company reports. Nabi expects NicVax to enter Phase III studies in the second half of 2005. The firm says the product has the potential for use as both an initial smoking cessation aid as well as longer-term relapse prevention. By producing antibodies to bind to nicotine, NicVax is designed to prevent nicotine from entering the brain, "thereby preventing the 'rush' that occurs when nicotine binds to receptors in the brain," the company explains.

Prolonged abstinence was significantly higher for 20 mg vs. placebo (36.2% vs. 20.6%), but only 20.2% for 5 mg rimonabant. The double-blind, placebo-controlled study, which enrolled 787 smokers who were motivated to quit but had previously failed, is the first of three Phase III studies in the STRATUS program; a European trial is ongoing, as is a one-year maintenance study, with data expected in the next 12 months. A selective CB1 blocker, rimonabant acts on the endocannabinoid system, which regulates the body's intake of food and is involved in tobacco dependency.
