The sleek, penlike iQOS device heats tobacco but does not burn it. The company hopes to convince the US Food and Drug Administration advisory panel that the product contains fewer harmful chemicals than cigarettes and reduces the risk of smoking-related diseases for smokers who switch.
The panel will discuss the company’s application for two days and on Thursday will vote on whether the company’s data supports one of three potential “modified risk” claims that would be used on the product’s label and in marketing.
The vote is not binding but will influence the FDA’s decision.
Electronic cigarettes currently on the market use a nicotine-laced liquid. Most toxic chemicals in cigarette smoke are produced when tobacco combusts.
IQOS is used by nearly 4 million people in 30 markets outside the United States but needs FDA authorisation to be marketed in America.
Philip Morris says iQOS produces up to 95 percent fewer potentially harmful chemicals than regular cigarettes. The company said if 15 percent of US daily smokers switched completely to iQOS it would translate to about 6 million smokers over seven to 10 years. The figure does not include smokers who might use iQOS in addition to cigarettes.
Moira Gilchrist, Philip Morris’ vice president of scientific and public communications, estimated that 90,000 smoking-related deaths could have been averted over 20 years based on an assumed switch rate of 15 percent.
The panel’s discussion comes amid an intense debate over the potential risks and benefits associated with e-cigarettes. On Tuesday, the National Academies of Sciences, Engineering and Medicine, summarising data from hundreds of scientific studies, said e-cigarettes are safer than cigarettes and help smokers quit. But the report also found “substantial evidence” that youths who use e-cigarettes are more likely to try traditional cigarettes.
FDA staff in a preliminary review of Philip Morris’ application said that iQOS contains fewer harmful chemicals than cigarettes but that it was unclear whether reduced exposure translates into reduced risk of disease.
Results of a study in mice that could shed additional light on additional cancer risk are expected in June.
