Primary

MeasureTime frame
Main Objective: · To determine the effect of V-073 and placebo treatment on poliovirus serotype 1 excretion in the stool after administration of mOPV1 as determined by virus culture; · To evaluate the safety and tolerability of multiple oral doses of V-073 administered to healthy volunteers;;Secondary Objective: · To evaluate the pharmacokinetics profile of V-073 after administration of multiple oral doses; · To determine the duration of poliovirus excretion in V-073 and placebo treated subjects; · To determine the levels of poliovirus excretion over time with V-073 or placebo treatment; · To compare the effectiveness of V-073 on poliovirus excretion when administered afterconsumption of a standard and high fat meal; · To determine the initial and post-V-073 treatment susceptibility of excreted poliovirus to V-073; · To determine the poliovirus-specific serum IgA and serum neutralizing (SN) antibody levels before and after treatment with V-073.;Primary end point(s): Pharmacokinetics: • The primary pharmacokinetic measure will be the single and multiple dose plasma pharmacokinetics of V-073 Pharmacodynamics: • Stool samples will be assessed for virus both qualitatively and quantitatively in a virusinduced cytopathic effect cell culture assay. • Stool samples may be assessed for virus qualitatively using poliovirus specific RT-PCR methodology.;Timepoint(s) of evaluation of this end point: Pharmacokinetics: • The primary pharmacokinetic measure will be the single and multiple dose plasma pharmacokinetics of V-073; • Pharmacokinetic parameters for Day 3 and Day 16 QD dosing will include Cmax, tmax, C24,AUC(0-tau),; • Cmin (trough) levels of V-073 will be determined by analyzing plasma samples collected prior to the morning dose on Days 4-16, and 24h after the last dose. Pharmacodynamics: The resulting virology data will be analyzed for the following endpoints - Time to virus excretion negativity for chloroform extracted samples. -Time to virus excretion negativity f

Secondary

MeasureTime frame
Secondary end point(s): Drug Susceptibility Group 1 to 4, Group 7 and 8: Virus from each subject's virus culture positive chloroform-extracted stool sample on Day 3 (or Day 2 if Day 3 sample is not available; pretreatment) and their last virus culture positive stool sample will be assessed for susceptibility to V-073 in a cell culture virus-induced cytopathic effect assay (EC50 determination). Virus samples with reduced drug susceptibility (defined as a >20-fold increase in EC50 value relative to the corresponding Day 3 [pretreatment] susceptibility) will be sequenced across the VP3 and VP1 protein coding regions to determine the genetic basis for reduced drug susceptibility. Safety: Safety and tolerability will be assessed by monitoring adverse experiences, measuring vital signs, electrocardiograms (ECGs), assessment of clinical laboratory determinations from blood samples, and performance of physical examinations Group 5 and 6: Drug Susceptibility: Virus from each subject’s virus culture positive chloroform-extracted stool sample on Day 1 (or Day 0 if Day 1 sample is not available; pretreatment) and their last virus culture positive stool sample will be assessed for susceptibility to V-073 in a cell culture virus-induced cytopathic effect assay (EC50 determination). Virus samples with reduced drug susceptibility (defined as a >20-fold increase in EC50 value relative to the corresponding Day 1 [pretreatment] susceptibility) will be sequenced across the VP3 and VP1 protein coding regions to determine the genetic basis for reduced drug susceptibility. Safety: Safety and tolerability will be assessed by monitoring adverse experiences, measuring vital signs, electrocardiograms (ECGs), assessment of clinical laboratory determinations from blood samples, and performance of physical examinations;Timepoint(s) of evaluation of this end point: Drug Susceptibility: Group 1 to 4, Group 7 and 8 Day 3 (or Day 2 if Day 3 sample is not available; pretreatment) and
