The Impact of Intravenous Bendavia™ on Endothelial Reactivity Dysfunction in Cigarette Smoking

A Phase 1, Placebo-Controlled Trial to Evaluate the Impact of Intravenous (IV) Bendavia™ (MTP-131) on Endothelial Reactivity Dysfunction Induced by Cigarette Smoking

This will be a phase 1 randomized, double-blind, 2-period, 2-sequence crossover trial enrolling 6 healthy volunteers to assess the impact of IV-administered Bendavia on the endothelial dysfunction induced by a single cigarette.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
PLACEBO_COMPARATOR: Placebo; Intravenous infusion of saline (0.9%) for 4 hours with smoking of one unfiltered cigarette at 30 minutes post-study-drug administration start	Drug: Sterile saline (0.9%); Sterile saline for infusion (0.9%) Intravenous infusion for 4 hours; Other: Cigarette smoking; One unfiltered cigarette will be smoked at approximately 30 minutes post-study-drug administration start.
EXPERIMENTAL: Bendavia; Intravenous infusion of Bendavia (0.25mg/kg/hr) for 4 hours with smoking of one unfiltered cigarette at 30 minutes post-study-drug administration start	Other: Cigarette smoking; One unfiltered cigarette will be smoked at approximately 30 minutes post-study-drug administration start.; Drug: Bendavia; Bendavia for infusion Intravenous infusion (0.25mg/kg/hr) for 4 hours

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Analysis of variance (ANOVA) between group mean endothelial function (EndoPAT Index) following smoking a single cigarette with and without Bendavia	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.	Baseline, +30, +60, +90 minutes post-study-drug administration start

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Anova between group mean inflammatory laboratory marker (hs-CRP; mg/L) after smoking one cigarette with and without Bendavia	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.	Baseline to 24 hours post-study-drug administration
ANOVA between group means of urinary 8-isoprostane (ng/mg of creatinine) after smoking one cigarette with and without Bendavia	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.	Baseline to 48 hours post-study-drug administration
Number adverse events with and without Bendavia	Adverse events will be tabulated by treatment group. No statistical analysis will be preformed.	Baseline to Study Day 10
Assessment of Bendavia exposure measured by area Under the Curve (AUC; ng*hr/mL)	Bendavia levels will be measured and pharmacokinetic parameters reported.	Baseline to 48 hours post-study-drug administration
ANOVA between group means of urinary 8-hydroxy-2'-deoxyguanosine (pg/mL) after smoking one cigarette with and without Bendavia	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.	Baseline to 48 hours post-study-drug administration
