Switching to Reduced Oxidant or Nicotine Content Cigarettes in Smokers

26. juli 2018 opdateret af: John P. Richie, Milton S. Hershey Medical Center

Switching to Reduced Nicotine Content Cigarettes or Reduced Reactive Oxygen/Reactive Nitrogen Species Cigarettes in Smokers

The overall objectives of this clinical study are to determine in smokers the short term effects of switching to tobacco products that deliver low levels of nicotine or reactive oxygen/nitrogen species (ROS/RNS) on smoking behavior and biomarkers of tobacco smoke exposure and oxidative stress.

Detaljeret beskrivelse

Researchers at Penn State Hershey are seeking healthy adult cigarette smokers between 21-65 who smoke any of the following brands on a regular basis: Marlboro Red, Marlboro Menthol, Pall Mall Red, Pall Mall Menthol, Kool Menthol, Salem Menthol, L&M Menthol, Pyramid Red, Newport Red, Newport Menthol.

If you smoke one of these brand styles on a regular basis you may be eligible to participate in a compensated short term study on health and smoking behavior at Penn State Hershey Medical Center.

Study participation lasts 22 days, with 4 study visits at the Medical Center. Smokers are asked to use their usual brand for one week and then switch to 1 of 3 brands for the remaining two weeks. The three brands participants are randomly assigned to after the first week of participation are either Group 1. reduced nicotine content cigarette (Spectrum Research Cigarettes) or Group 2. reduced oxidant cigarette (American Spirit) or assigned to Group 3. usual brand. Whichever group you are assigned to, you will be asked to smoke only these until the end of the study. All cigarettes following visit 1 will be provided free of charge.

Study overview:

Visit 1/ Duration: 60 minutes Provide a blood and urine sample Complete a 20 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day

Visit 2: Randomized Phase /Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day

Visit 3/ Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Use a simple, hand held smoking device to smoke all cigarettes for 2 days Collect cigarette butts on 1 day

Visit 4/ Duration: 20-30 minutes Provide a blood and urine sample Complete a 10 minute interview Sign compensation form

Beskrivelse

Inclusion Criteria:

  • Age 21-65
  • Smoke 10 cigarettes/day or more for at least one year
  • Read and write in English
  • Menthol and nonmenthol smokers who use relatively high nicotine and ROS/RNS cigarettes
  • Able to understand and provide consent to study procedures
  • Plan to live in the local area for the next month
  • Women not pregnant or nursing and taking steps to avoid pregnancy
  • No quit attempt in the last one months and not planning to quit in the next month

Exclusion Criteria:

  • Currently pregnant or nursing
  • Unstable or significant medical condition, such as COPD or kidney failure, that is likely to affect biomarker data
  • Use of non-cigarette nicotine delivery product in the past week (included cigars, pipes, chew, snus, hookah, e-cig, and marijuana)
  • Currently reducing or planning to reduce cigarette consumption in the next month
  • Use of smoking cessation medicine in the past 3 months
  • History of difficulties providing blood samples: fainting, poor veins, anxiety, etc.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Reduced Nicotine Cigarettes
Participants will be randomized to receive low nicotine cigarettes to replace their usual high nicotine brand.
Andet: Reduced Nicotine Cigarettes
Human topography data will show if smokers smoke their cigarettes differently from baseline following randomization. Select biosamples of participants will be used to analyze how biomarkers differ among groups
Andre navne:
  • Cigarette contains .28mg (.29mg/menthol) of nicotine
Eksperimentel: Reduced ROS/RNS
Participants will be randomized to receive Reduced Oxidative/Nitrogen Species (ROS/RNS) cigarettes to replace their usual cigarettes.
Andet: Reduced ROS/RNS
Human topography data will show if smokers smoke their cigarettes differently from baseline following randomization. Select biosamples of participants will be used to analyze how biomarkers differ among groups
Andre navne:
  • Cigarette to be determined by lab experiment
Placebo komparator: Control Group
Participants will be assigned to continue smoking their usual brand of cigarettes.
Andet: Control
Human topography data will show if smokers change the way they smoke due to being in a research study. Select biosamples of participants will be used to analyze how biomarkers differ among groups
