Dose-normalized Area Under the Concentration-Time Curve in 1 Dosing Interval (AUC[TAU]/D) of Daclatasvir
AUC(TAU)/D was obtained from concentration-time plot of daclatasvir by using noncompartmental method by a validated pharmacokinetic analysis program.
Time frame: Predose (0 hour) on Day 2, 3 and 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 hours on Day 4 (Period 1); Predose (0 hour) on Day 12, 13 and 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 hour on Day 14 (Period 2)
Number of Participants With Serious Adverse Events (SAEs) and Discontinuations Due to Adverse Events (AEs) and Who Died
AE was defined as any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with treatment.
