After hybridization, the resulting DNA-morpholino molecule (hybrid) was subjected to analysis by capillary gel electrophoresis with laser-induced fluorescence detection. Quantification of the fluorescent hybrid by capillary gel electrophoresis hybridization was determined by normalizing the fluorescence intensity of each hybrid peak to an unrelated fluorescent internal standard peak, whereby changes in the normalized value were proportional to changes in AVI-7288 analytic concentrations in different samples. The hybrid peak fluorescence correlated to analyte quantity in a range of 1.9 ng/mL to 29.5 ng/mL plasma. Concentrations below the lower limit of quantitation were reported as BLOQ. The method was validated by meeting acceptance criteria for selectivity, range of response, dilution linearity, lower and upper limits of quantitation, intra- and inter-assay accuracy and precision, multiple stability assessments, and recovery. 5 Bioanalytic Assay for Determining AVI-7288 Levels in Human Plasma The method for determination of AVI-7288 in human plasma employed a detector reagent comprised of a complementary oligonucleotide probe with terminal fluorescein label, which directly hybridized to the AVI-7288 analyte in human plasma after TRIzol LS extraction and alcohol precipitation. After hybridization, the resulting DNA-morpholino molecule (hybrid) was subjected to analysis by capillary gel electrophoresis with laser-induced fluorescence detection. Quantification of the fluorescent hybrid by capillary gel electrophoresis hybridization was determined by normalizing the fluorescence intensity of each hybrid peak to an unrelated fluorescent internal standard peak, whereby changes in the normalized value were proportional to changes in AVI-7288 analytic concentrations in different samples. The hybrid peak fluorescence correlated to analyte quantity in the range of 2.9 to 47.1 ng/mL in plasma. Concentrations below the lower limit of quantitation were reported as BLOQ. The method was validated by meeting acceptance criteria for selectivity, range of response, dilution linearity, lower and upper limits of quantitation, intra- and inter-assay accuracy and precision, multiple stability assessments, and recovery. 6 Figure S1. Area under the Curve and Maximum Plasma Concentration in Infected and Uninfected Nonhuman Primates (A) Area under the plasma concentration-time curve from time 0 to 24 hours after the start of infusion of study drug (AUC0-24) and (B) maximum plasma concentration (Cmax) were generally dose-proportional over the range of doses tested (3.75, 7.5, and 15 mg/kg) on day 1 in infected nonhuman primates (red) and uninfected nonhuman primates (blue) in the dedicated nonhuman primate pharmacokinetic studies. Values depicted are mean ± standard deviation. 7 Figure S2. Maximum Plasma Concentration in Uninfected Humans Maximum plasma concentration (Cmax) was generally dose-proportional over the range of doses tested (1, 4, 8, 12, and 16 mg/kg) in uninfected humans in the multiple ascending dose study at day 1 (red) and day 14 (blue). Values depicted are mean ± standard deviation. 8 Figure S3. Clearance in Infected and Uninfected Nonhuman Primates Plasma clearance was independent of dose over the range of doses tested (3.75, 7.5, and 15 mg/kg) in infected nonhuman primates (red) and uninfected nonhuman primates (blue) on day 1 in the dedicated nonhuman primate pharmacokinetic studies. Slope was not significantly different from 0 for infected or uninfected nonhuman primates (p=0.307 and p=0.222, respectively). 9 Figure S4. Clearance in Uninfected Humans Plasma clearance was independent of dose over the range of doses tested (1, 4, 8, 12, and 16 mg/kg) in uninfected humans on day 14 in the multiple ascending dose study. Slope was not significantly different from 0 (p=0.06). 10 Figure S5. Area under the Curve and Clearance of AVI-7288 in Infected and Uninfected Nonhuman Primates (A) Area under the plasma concentration-time curve from time 0 to 24 hours after the start of infusion of study drug (AUC0-24) and (B) plasma clearance of AVI-7288 15 mg/kg were similar in infected nonhuman primates (red) and uninfected nonhuman primates (blue) at day 1, day 5, day 10, and day 14, suggesting that viral infection did not impact the pharmacokinetics of AVI7288. 11 Figure S6. Maximum Plasma Concentration after Intramuscular and Intravenous Administration of AVI-7288 in Uninfected Nonhuman Primates Maximum plasma concentration (Cmax) after intramuscular administration of AVI-7288 (red) was lower than Cmax after intravenous administration of AVI-7288 (blue) in uninfected nonhuman primates on day 1. Values depicted are mean ± standard deviation. 12 Table S1.
