ListOutcomeTime frameDescription
PrimaryIncidence of Treatment-Emergent Adverse Events (TEAEs) Grade ≥3Day 1 through Day 28Type and frequency of treatment-emergent adverse events of Grade 3 or higher
PrimaryChange in Viral Load Slope (RT-PCR Ct Values)Day 1 to Day 10Change in slope of Lassa virus RT-PCR cycle threshold (Ct) values between Day 1 and Day 10 in participants with low baseline Ct values.
SecondaryChange in Viral Load Slope in Participants with Other Baseline Ct ValuesDay 1 to Day 10Change in slope for LASV RT-PCR Ct values between Day 1 and Day 10, for subjects with other baseline Ct values (to be determined \[TBD\], subsequent to RT-PCR methods validation).
SecondaryChange in RT-PCR Ct Values at Prespecified Timepoints (Change in Ct values. between Day 1 and Days 2, 3, 4, 6, 8, and 10).Day 1 to Day 10Change in Ct values between Day 1 and each of Days 2, 3, 4, 6, 8, and 10 for the ARN-75039 arms vs SOC for those with baseline Ct \<30 (or other Ct values TBD).
SecondaryTime to First RT-PCR Result Below Lower Limit of Quantification (LLOQ)Day 1 to Day 28Time to reach lower limit of quantification \[LLOQ\] and undetectable Ct values.
SecondaryTime to First Undetectable Lassa Virus RT-PCR ResultDay 1 to Day 28Time to reach undetectable Ct values.
SecondaryProportion of Participants With RT-PCR <LLOQDay 1 to Day 28LASV RT-PCR \<LLOQ (% of participants) for specified baseline Ct values (TBD).
SecondaryProportion of Participants With Undetectable RT-PCRDay 1 to Day 28LASV RT-PCR undetectable (% of participants) for specified baseline Ct values TBD.
SecondaryEstimated Baseline Lassa Virus RT-PCR Cycle Threshold (Ct) Value (Intercept) from Linear Mixed-Effects ModelDay 1
Estimated baseline Lassa virus RT-PCR cycle threshold (Ct) value derived from a linear mixed-effects model of longitudinal Ct measurements collected between Day 1 and Day 10. Results will be reported as model-estimated mean Ct value (Ct units).
SecondaryEstimated Rate of Change in Lassa Virus RT-PCR Ct Value (Ct Units per Day) from Linear Mixed-Effects Model.Day 1 to Day 10
Estimated rate of change (slope) in Lassa virus RT-PCR cycle threshold (Ct) values over time, calculated using a linear mixed-effects model of longitudinal Ct measurements from Day 1 through Day 10. Results will be reported as mean change in Ct units per day (Ct/day).
SecondaryChange in Ct values stratified by Lassa lineage (Ct <30)Day 1 to Day 10Change in Ct values stratified by Lassa lineage for subjects with baseline Ct \<30 or other baseline Ct values TBD.
SecondaryPharmacokinetic Outcome: ARN-75039 AUC₀-tDay 1 through Day 10Area under the plasma concentration-time curve from time 0 to time of last quantifiable concentration.
SecondaryPharmacokinetic Outcome: ARN-75039 AUC₀-∞Day 1 through Day 10Area under plasma concentration-time curve from time 0 to infinity.
SecondaryPharmacokinetic Outcome: ARN-75039 CmaxDay 1 through Day 10Maximum observed plasma concentration.
SecondaryPharmacokinetic Outcome: ARN-75039 Ctrough (Cmin0-24hr)Day 1 through Day 10Trough concentration (Ctrough) exposures: Cmin(0-24hr) exposures taken prior to first dose on Days 2, 4, and 10.
SecondaryPharmacokinetic Outcome: ARN-75039 TmaxDay 1 through Day 10Time to reach Cmax
SecondaryPharmacokinetic Outcome: t½Day 1 through Day 10ARN-75039 half-life
SecondaryPharmacokinetic Outcome: ARN-75039 apparent clearance (CL/F)Day 1 through Day 10Apparent Clearance
SecondaryPharmacokinetic Outcome: ARN-75039 apparent volume of distribution (Vz/F)Day 1 through Day 10Apparent volume of distribution during the terminal phase.
SecondaryAssociation Between ARN-75039 Plasma Exposure (AUC₀-t) and Change in Lassa Virus RT-PCR Ct Value.Day 1 to Day 10
The association between individual plasma exposure to ARN-75039, measured as area under the concentration-time curve from time 0 to time of last quantifiable concentration (AUC₀-t), and change in Lassa virus RT-PCR cycle threshold (Ct) values from Day 1 to Day 10 will be evaluated using linear regression modeling. Results will be reported as regression slope (change in Ct per unit increase in AUC) with corresponding 95% confidence intervals.
