Study Assessing the Effects of Darunavir/Ritonavir or Lopinavir/Ritonavir on the Pharmacokinetics of Daclatasvir in Healthy Participants

Cmax was obtained from concentration-time plot using a noncompartmental method and a validated pharmacokinetic analysis program.

AUC(TAU) was the area under the curve from time zero to end of dosing interval. AUC(TAU) was obtained from concentration-time plot of daclatasvir using noncompartmental method and a validated pharmacokinetic analysis program.

Tmax was obtained from concentration-time plot of daclatasvir by using non-compartmental method by a validated pharmacokinetic analysis program.

C24 was obtained from concentration time plot of daclatasvir by using noncompartmental method by a validated pharmacokinetic analysis program.

Cmax/D and C24/D are obtained from concentration-time plot of daclatasvir by using noncompartmental method by a validated pharmacokinetic analysis program.

AUC(TAU)/D was obtained from concentration-time plot of daclatasvir by using noncompartmental method by a validated pharmacokinetic analysis program.

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. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization.

Criteria for abnormalities in vital sign measurements: Diastolic blood pressure: Value >90 and change from baseline > 0 or value < 55 and change from baseline <-10. Systolic blood pressure: Value >140 and change from baseline >20 or value <90 and change from baseline <-20. Heart rate: Value >100 and change from baseline >30 or value <55 and change from baseline <-15. Respiration: Value >16 or change from baseline >10. Temperature: Value >38.3°C or change from baseline >1.6°C.

Abnormalities in ECG findings included: PR ≥210 msec, QRS ≥120 msec, QT ≥500 msec, QTcF ≥450 msec, and second- or third-degree heart block.

Criteria for marked abnormalities in test results: Platelet count >1.5*upper limits of normal (ULN) value, >1.5*ULN if pretreatment (PreRx) value is missing, <0.85*lower limit of normal (LLN) if PreRx ≥LLN, <0.85*LLN if PreRx is missing, <0.85*PreRx if PreRx <LLN. Leukocytes >1.2*ULN if LLN ≤PreRx ≤ULN, >1.2*ULN if PreRx is missing, >1.5*PreRx if PreRx >ULN, >ULN if PreRx <LLN, <0.85*PreRx if PreRx <LLN, <0.9*LLN if LLN ≤PreRx ≤ULN, <0.9*LLN if PreRx is missing and <LLN if PreRx >ULN. Lymphocytes >7.5*10^3 c/uL and <0.75*10^3 c/uL. Neutrophils <0.85*PreRx if PreRx <1.5*ULN, <1.5*ULN if PreRx ≥1.5*ULN and <1.5*ULN if PreRx is missing.

Criteria for marked abnormalities on laboratory test results: urinary dipstick blood: ≥2 if pretreatment (PreRx) <1, ≥2 if PreRx is missing or ≥2*PreRx if PreRx ≥1. Urinary microscopic red blood cell (RBC): ≥2 if PreRx <2, ≥2 if PreRx is missing or ≥4 if PreRx ≥2. Urinary microscopic white blood cell (WBC): ≥2 if PreRx <2, ≥2 if PreRx is missing or ≥4 if PreRx ≥2. Lactate dehydrogenase >1.25*upper limit of normal (ULN) if PreRx ≤ULN, >1.25*ULN if PreRx is missing and >1.5*PreRx if PreRx >ULN.
