Firm designs nasal spray to fight obesity

Dieters may find some welcome assistance from a new nasal spray that could help resist the appetizing aromas of cinnamon bun stands, pizza parlors or tempting bakeries.

Compellis Pharmaceuticals of Cambridge, Massachusetts said it will begin human trials next year of a nasal spray designed to fight obesity by blocking the senses of smell and taste. It won a patent for the product this month.

"The pleasurable effect of eating is all stimulated by smell and taste," Christopher Adams, the company's founder and chief executive, told Reuters on Tuesday.

"The premise is that olfactory activity that controls both smell and taste is a trigger and a feedback mechanism to eat. If you have some kind of reduced sense of smell or taste, you tend to eat less," he said.

The product, known as CP404, is among the latest devices and treatments under development in the multibillion-dollar fight against obesity.

An estimated 65 percent of adult Americans are overweight or obese, putting them at higher risk of heart disease, diabetes and other conditions that account for more than $100 billion of the country's $1.9 trillion annual healthcare bill.
