Phase:

PHASE1

Brief Summary

The objectives of this study are: 1. To assess the tolerability and safety of cytisine as a single oral dose. 2. To define the Cmax levels associated to the occurrence of dose-limiting adverse events...

  • Known severe hypersensitivity to any other drug.
  • Positive urinary drugs of abuse screen, determined within 28 days before cytisine/placebo dosing.
  • Positive ethanol breath test.
  • Clinically significant abnormal serum chemistry, hematology, coagulation or urinalysis values within 28 days of randomization (i.e. requiring treatment or monitoring).

  • Participation in a clinical study with an investigational drug within the previous 2 months.
  • Participation in more than 2 clinical trials within the previous 12 months.
  • Any other reason that the investigator views the subject should not participate or would be unable to fulfill the requirements for the study.
  • Subjects meeting ANY of the following exclusion criteria will NOT be eligible for inclusion into the study at admission to each cohort.
