MeasureTime frameDescription
Number of Participants With Serious Adverse Events (SAEs), Discontinuations Due to Adverse Events (AEs) and Who DiedDay 1 up to Day 7 for non-SAEs and Day 1 to 30 days after study discontinuation for SAEsAEs were defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding) or disease which either occurs during study, whether or not related to the study drug. SAEs were defined as any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgement of investigators represent significant hazards.
Number of Participants With Clinically Significant Change From Baseline in Vital Sign Measurements and Physical Examination FindingsDay 1 up to Day 7 or DischargeParticipants were assessed by investigator for any clinically significant changes in vital parameters like body temperature, respiratory rate, blood pressure, heart rate and weight. The assessment was performed by a calibrated sphygmomanometer and thermometer for blood pressure and temperature, respectively. Blood pressure and heart rate were measured after at least 5 minutes quiet seating of the subject. Weight was measured at the discharge. The criteria for clinically significant change was as per the investigators discretion.
Number of Participants With Marked Abnormalities in Laboratory FindingsDay 1 up to Day 7Laboratory marked abnormalities were defined as Hematocrit (low) as \<0.85\*pre-treatment value, Leukocytes (low) as \<0.9\*lower limit of normal, Aspartate Aminotransferase (high) as \>1.25\*upper limit of normal, Creatinine (high) as \>1.33\*pre-treatment value, Bicarbonate (high) as \>1.2\*upper limit of normal, Total Protein (high) as \>1.1\*upper limit of normal, Creatinine Kinase (high) as \>1.5\*upper limit of normal, Blood in Urine (high) as ≥ 2\*upper limit of normal. Participants were fasted for at least 10 hours prior to the collection of blood specimens for clinical laboratory tests.

C-12 and C-24 were defined as observed plasma concentration of daclatasvir at 12 hours and 24 hours, respectively. The plasma samples were analyzed for daclatasvir using a validated liquid chromatography-tandem mass spectrometric assay.
Change From Baseline in Heart Rate to Day 7 or DischargeBaseline (Day 1), Day 7 or DischargeChanges in heart rate from baseline were measured after the participants were supine for at least 5 minutes. Baseline was defined as the Day 1 pre-dose measurement. The normal heart rate lies between 60-90 beats per minute (bpm), below 60 bpm and above 90 bpm were considered as bradycardia and tachycardia, respectively.

Baseline was defined as the Day 1 pre-dose measurement. The PR interval was defined as the beginning of the P wave to the beginning of the QRS complex, and represents the time taken by electrical impulse to travel from the sinus node through the atrioventricular (AV) node. The QRS complex represented the rapid depolarization of the right and left ventricles. The QT interval was defined as the time from the start of the Q wave to the end of the T wave, and represents the time taken for ventricular depolarization and repolarization. QTc was defined as corrected QT interval at a heart rate of 60 bpm. QTc was estimated using Bazett's formula and Fredericia's formula.

Change From Baseline in Heart Rate to Day 7 or Discharge

Changes in heart rate from baseline were measured after the participants were supine for at least 5 minutes. Baseline was defined as the Day 1 pre-dose measurement. The normal heart rate lies between 60-90 beats per minute (bpm), below 60 bpm and above 90 bpm were considered as bradycardia and tachycardia, respectively.

Time frame: Baseline (Day 1), Day 7 or Discharge

Population: The analysis was performed in the safety population.

Decline From Baseline in log10 Hepatitis C Virus (HCV) Ribonucleic Acid (RNA)

The Roche TaqMan HCV quantitative assay was used for analysis with detection limit of 10 IU/mL. Positive value indicated reduction from baseline in HCV RNA while negative value indicated an increase from baseline in HCV RNA. Baseline HCV RNA was defined as the pre-dose value on Day 1 log10 HCV RNA.

Time frame: Pre-dose, 2, 4, 6, 8, 12, 16, 24, 36, 48, 72 and 144 hours post-dose on Day 1

Maximum Observed Plasma Concentration (Cmax) and Observed Plasma Concentration at 12 Hours (C-12) and 24 Hours (C-24)

Maximum observed plasma concentration following drug administration from the raw plasma concentration-time data. C-12 and C-24 were defined as observed plasma concentration of daclatasvir at 12 hours and 24 hours, respectively. The plasma samples were analyzed for daclatasvir using a validated liquid chromatography-tandem mass spectrometric assay.

Time frame: Pre-dose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 10, 12, 16, 24, 48 and 72 hours post-dosing on Day 1

Population: The analysis was performed in the pharmacokinetic (PK) set population defined as all participants who received at least single dose of daclatasvir with available valid data.
