Star Scientific Files Application with FDA for Ariva-BDL(TM) Approval as First 
Modified Risk Tobacco Product 
 
GLEN ALLEN, Va., Feb. 25 /PRNewswire-AsiaNet/ -- 
 
    Star Scientific, Inc. (Nasdaq: CIGX) announced that on Friday, February 19 the 
company filed an application with the Food & Drug Administration for approval to 
market Ariva-BDL(TM) as a "modified risk" tobacco product under the Family Smoking 
Prevention and Tobacco Control Act of 2009. This submission is the first such 
application to be filed with the Tobacco Products Center of the FDA, which has been 
established to oversee all aspects of tobacco regulation outlined in the 2009 Act. 
 
 
    Ariva-BDL(TM), a dissolvable tobacco lozenge with wintergreen flavoring, 
is made with flue-cured tobacco that contains levels of tobacco-specific 
nitrosamines (TSNAs) that are below detectable limits ("BDL") by most current 
standards of measure. TSNAs have been identified in scientific literature 
since the early 1950s as one of the most deadly and abundant groups of 
carcinogens in tobacco and its smoke. Achieving this reduction, known within 
Star as "ZNT" (zero-nitrosamine tobacco) was accomplished by new work on the 
StarCured(R) tobacco curing technology that originally was developed in the 
1990s. This innovation is the subject of a patent application filed in 
December 2008. A recent article by Rickert et al. (Regulatory Toxicology and 
Pharmacology 2009;53(2):121-33) reported total TSNA levels in currently 
marketed popular moist snuff and "pouch" tobacco products that ranged from 
8,814 - 14,557 parts per billion. This range is 1000 times greater than the 
levels measured in Ariva-BDL(TM), as outlined in the company's submission. 
 
    Star Scientific believes these developments are of great significance in 
light of the reality that 43 million Americans -- roughly half of them women 
-- smoke each day. More than half of this population is looking for an 
acceptable alternative to cigarettes. Cigarette revenues in the United States 
currently total $75 - $80 billion, according to the Wall Street Journal. 
While a number of male smokers in the US now use traditional smokeless 
tobacco as an alternative to smoking, female smokers do not accept the 
unpleasant aesthetics of using moist snuff. As a completely dissolvable 
lozenge, Ariva-BDL(TM) would offer a useful alternative -- with greatly 
reduced toxin levels -- to adult smokers of both genders. 
 
    Star Scientific originally introduced dissolvable smokeless tobacco to 
the marketplace almost ten years ago when it launched Ariva(R) in 2001, and 
Stonewall Hard Snuff(R) in 2003. Both products are pieces of powdered and 
compressed StarCured(R) tobacco that dissolve completely in the mouth and 
leave no residue. Ariva(R), launched in 2001, was developed for adult 
dependent smokers who cannot or choose not to smoke. Stonewall Hard Snuff(R), 
launched in mid-2003, is an alternative for adults who use traditional 
smokeless tobacco products or who identify themselves as "heavy smokers". 
Over the past nine years the company has learned that Ariva(R) customers 
range in age from 30 - 70, and more than half of whom are women. Stonewall 
Hard Snuff(R) purchasers range in age from 25 - 65. Customers who are looking 
for an alternative to moist snuff are largely male, while roughly 30 - 40% of 
those who purchase the products as an alternative to "heavy" daily cigarette 
smoking are female. According to callers to the product consumer call center, 
the majority of purchasers are concerned about continued smoking. Both Ariva 
and Stonewall are available with wintergreen flavoring, which have been the 
blend most often purchased by Star's customers. 
 
    Ariva(R) and Stonewall(R) were the subjects of a federally funded pilot 
study published last month in Nicotine & Tobacco Research that was conducted 
at the Medical Center of South Carolina. The two-week study involved 
recruiting smokers uninterested in quitting cigarettes who randomly were 
either given Ariva(R) or Stonewall(R), or continued smoking cigarettes. The 
data analysis revealed that among the Ariva/Stonewall group there was a 40% 
reduction in cigarettes smoked per day, and "significant increases in two 
measures of readiness to quit, either in the next month or within the next 
six months. No such changes were found among smokers maintained on 
conventional cigarettes". 
 
    When Star had the opportunity to read the published study, the company's 
management team was gratified by this new information but did not consider 
the authors' conclusions unexpected. The independent Scientific Advisory 
Board that provided input on tobacco-related research to Star directed the 
company's attention to a body of research indicating that smoking rates among 
Swedish men (17.9%) were probably among the lowest in the developed world, a 
dramatic reduction from much higher smoking rates (36%) twenty years before. 
During the intervening two decades a transition in tobacco use occurred: 20% 
of Swedish men were now users of snus, Swedish smokeless tobacco that 
contained reductions in TSNAs. Epidemiological studies concluded in the 
period 1998 - 2001 found no increase in head or neck cancers, while lung 
cancer deaths had fallen, among Swedish men. 
 
    The company believes that Ariva-BDL(TM), if approved, will be highly 
attractive to other companies. For this reason, Star has committed to 
exploring opportunities for sublicensing agreements with both domestic and 
international entities, so that Ariva-BDL(TM) can be made available as 
broadly as possible to adult dependent smokers.
