Primary Outcome Measures:
  • Analysis of variance (ANOVA) between group mean endothelial function (EndoPAT Index) following smoking a single cigarette with and without Bendavia [ Time Frame: Baseline, +30, +60, +90 minutes post-study-drug administration start ] [ Designated as safety issue: No ]

    Endothelial function will be determined using EndoPAT 2000 (Itamar Medical Ltd) prior to and after smoking of one unfiltered cigarette and prior to and after initiation of study drug. Group comparison of endothelial function (EndoPAT Index) between placebo and active study drug within a subject will be performed.

    EndoPAT quantifies the endothelium-mediated changes in vascular tone. A post-occlusion to pre-occlusion ratio is calculated providing the EndoPAT index.



Secondary Outcome Measures:
  • Anova between group mean inflammatory laboratory marker (hs-CRP; mg/L) after smoking one cigarette with and without Bendavia [ Time Frame: Baseline to 24 hours post-study-drug administration ] [ Designated as safety issue: No ]
    hs-CRP will be evaluated prior to and after smoking of one unfiltered cigarette and prior to and after initiation of study drug. Group comparison of hs-CRP levels between placebo and active study drug within a subject will be performed.

  • ANOVA between group means of urinary 8-isoprostane (ng/mg of creatinine) after smoking one cigarette with and without Bendavia [ Time Frame: Baseline to 48 hours post-study-drug administration ] [ Designated as safety issue: No ]
    8-isoprostane will be measured prior to and after smoking of one unfiltered cigarette and prior to and after initiation of study drug. Group comparison of laboratory results between placebo and active study drug within a subject will be performed.

  • Number adverse events with and without Bendavia [ Time Frame: Baseline to Study Day 10 ] [ Designated as safety issue: Yes ]
    Adverse events will be tabulated by treatment group. No statistical analysis will be preformed.

  • Assessment of Bendavia exposure measured by area Under the Curve (AUC; ng*hr/mL) [ Time Frame: Baseline to 48 hours post-study-drug administration ] [ Designated as safety issue: No ]
    Bendavia levels will be measured and pharmacokinetic parameters reported.

  • ANOVA between group means of urinary 8-hydroxy-2'-deoxyguanosine (pg/mL) after smoking one cigarette with and without Bendavia [ Time Frame: Baseline to 48 hours post-study-drug administration ] [ Designated as safety issue: No ]
    8-hydroxy-2'-deoxyguanosine will be measured prior to and after smoking of one unfiltered cigarette and prior to and after initiation of study drug. Group comparison of laboratory results between placebo and active study drug within a subject will be performed.
