An Exploratory Study Comparing Two Nicotine Inhalers

Status Completed

Clinical Trial Summary

Subjects will be screened within 28 days before the first study treatment to confirm that they meet the requirements to participate in the trial. They will return to the site for two treatment visits, at least 12 hours each, and at least one day in between visits. At each visit treatment N1/3-I5 or Nicotine Inhaler 10 mg will be administered every hour for 11 hours. The investigator (or an appropriate delegate at the investigator site) will obtain informed consent from each subject. Blood samples will be drawn on a special schedule. The total predicted amount of blood sampled from each subject is 174 mL over the whole study. Subjects will be required to follow specific smoking and dietary restrictions and rate their urges to smoke, general liking of the product, and how easy the product is to use.

Clinical Trial Description

Blood for pharmacokinetic analyses will be drawn prior to the first administration and immediately before administration at 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 11 hours. Thereafter samples will be drawn at 5, 10, 15, 20, 25, 30, 45, and 60 minutes after the 11-hour administration. Easiness of use will be rated using an 8-grade ordered category scale at 10 minutes after the start of administrations at 3, 6, and 9 hours. Overall liking will be rated using an 8-grade ordered category scale at 12 hours. Urges to smoke will be rated on a 4-grade ordered category scale immediately before and at 15 minutes after the first administration, and as well as before and 15 minutes after the start of administrations at 3, 6, and 9 hours, and at 12 hours. Used cartridges will be collected. Pooled samples per subject and treatment will be analyzed to determine the amount of remaining nicotine. Tolerability of the treatments will be evaluated in terms of reported and observed adverse events (AE).

Since the primary objective is to compare steady-state nicotine pharmacokinetics of N1/3-I5 with that of Nicotine Inhaler 10 mg, this study will have a multiple-dose setting. A crossover design has been chosen for this study in order to allow within-subject comparisons of treatments. Healthy habituated adults smoking at least 10 cigarettes daily for at least one year preceding inclusion will be included in the study, since they are expected to tolerate the doses of nicotine that will be administered. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
