JAMA Publishes Greatly Anticipated Phase III Study Using 22nd Century’s SPECTRUM® Very Low Nicotine Content Cigarettes

22nd Century Group, Inc. (NYSE American: XXII), a plant biotechnology company focused on tobacco harm reduction and Very Low Nicotine tobacco, announced that the Journal of the American Medical Association (JAMA) published results of a greatly anticipated independent clinical study investigating the effects of an immediate reduction in nicotine content of cigarettes versus a gradual reduction in nicotine content of cigarettes. Dr. Dorothy Hatsukami and other highly respected scientists used exclusively 22nd Century’s SPECTRUM® research cigarettes to conduct this study.


In this randomized, parallel, double-blind clinical study, which is the largest clinical study using Very Low Nicotine Content (VLNC) cigarettes conducted to date, independent scientists assigned 1,250 participants to one of three groups: (1) smokers who were provided only with cigarettes containing VLNC tobacco with 0.4 mg of nicotine per gram of tobacco, (2) smokers who were provided with cigarettes with a gradual reduction of nicotine from 15.5 mg to 0.4 mg of nicotine per gram of tobacco, and (3) smokers who were provided with cigarettes of a conventional nicotine level with 15.5 mg of nicotine per gram of tobacco.


This timely trial addresses a key question posed by the FDA in the Agency’s March 2018 Advance Notice of Proposed Rulemaking (ANPRM) to lower nicotine in cigarettes to minimally or non-addictive levels: Which is better for public health… an immediate or a gradual reduction in nicotine?


Following 2 weeks of baseline study and 20 weeks of intervention, an immediate reduction in nicotine emerged as the clear winner. Compared to a gradual nicotine reduction, an immediate nicotine reduction was associated with:

  • Lower toxicant exposure across time
  • Fewer cigarettes smoked per day
  • Greater reduction in nicotine dependence
  • More days in which participants smoked no cigarettes (cigarette-free days)

In contrast, results from those assigned to a gradual reduction in nicotine were nearly indistinguishable from the results of those assigned to cigarettes with a conventional level of nicotine in the areas of dependence, number of cigarette-free days, cigarettes smoked per day, and most of the biomarkers of nicotine and tobacco smoke exposure.


In a companion article published by the University of Minnesota, Dr. Dorothy Hatsukami, Professor of Psychiatry at the University of Minnesota Medical School, remarked: “The results support the benefits of rapidly reducing nicotine in all cigarettes, primarily because this approach helped smokers, who initially had no immediate intentions to quit, experience smoke-free days. This is good news because the majority of smokers want to quit smoking, but only a small percentage of smokers are successful.”


“The results of this large, independent clinical study significantly add to the already extensive array of published clinical studies that have been conducted with 22nd Century’s VLNC cigarettes,” explained Juan Sanchez Tamurrino, Vice President of Research and Development at 22nd Century. “The results of Dr. Hatsukami’s study will serve to strengthen further the case for VLNC cigarettes to benefit public health even as 22nd Century finalizes the Company’s revised Modified Risk Tobacco Product (MRTP) application for our BRAND A Very Low Nicotine cigarettes that will be submitted to the FDA before the end of this year.”


“The peer-reviewed results of this latest independent clinical study serve to confirm and expand the knowledge gained through Dr. Eric Donny’s Randomized Trial of Reduced-Nicotine Standards for Cigarettes that was published in the October 2015 issue of TheNew England Journal of Medicine,” explained Henry Sicignano III, President and Chief Executive Officer of 22nd Century Group. “With the data from the many completed, independent clinical studies using 22nd Century’s VLNTM tobacco and technology, the FDA may accelerate plans to require that all cigarettes sold in the U.S. contain only minimally or non-addictive levels of nicotine. To this end, 22nd Century stands ready to license our non-addictive tobacco to all tobacco companies that are truly committed to improving the health of smokers.”
