MeasureTime frameDescription
Number of Participants with Adverse Events (AEs)Up to Day 120An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.
Maximum Observed Serum Concentration (Cmax) of ABBV-142Up to Day 120Cmax of ABBV-142 will be assessed.
Time to Cmax (Tmax) of ABBV-142Up to Day 120Tmax of ABBV-142 will be assessed.
Area Under the Serum Concentration-time Curve (AUC) of ABBV-142 from Time 0 to the Time of Last Measurable Concentration (AUCt)Up to Day 120AUCt of ABBV-142 will be determined.
AUC of ABBV-142 from Time 0 to Infinity (AUCinf)Up to Day 120AUCinf of ABBV-142 will be assessed.
Terminal Phase Elimination Rate Constant (β) of ABBV-142Up to Day 120Terminal phase elimination rate constant (β) of ABBV-142 will be assessed.
Terminal Phase Elimination Half-life (t1/2) of ABBV-142Up to Day 120Terminal phase elimination half-life (t1/2) of ABBV-142 will be assessed.
Dose Normalized Cmax of ABBV-142Up to Day 120Dose normalized Cmax of ABBV-142 will be assessed.
Dose Normalized AUC of ABBV-142Up to Day 120Dose normalized AUC of ABBV-142 will be assessed.
