RBV (ribavirin) 
• Genotype 1b: VIEKIRA PAK (ombitasvir, paritaprevir/r, dasubuvir) 
Indication 
Treatment  of  patients  with  genotype  1  chronic  hepatitis  C  virus  (HCV) 
infection 
Primary Objective 
The  primary  objective  of  this  open  label  study  is  to  evaluate  the  rate  of 
sustained virological response rate 12 weeks after completion of treatment 
(SVR12) with VIEKIRA PAK (ombitasvir, paritaprevir/r, dasubuvir), with 
or without ribavirin in a large real world setting. 
Overview  of  Study 
Design 
This is a Phase IV, open-label, multi-center study to evaluate the real world 
sustained virological response rate, subject adherence, and subject reported 
outcomes  during  and  after  treatment  of  non-cirrhotic  genotype  1  chronic 
hepatitis C subjects aged 18 years and older, with the AbbVie 3 direct-acting 
antiviral  (3-DAA)  regimen  of  VIEKIRA  PAK  (ombitasvir,  paritaprevir/r, 
dasubuvir),  with  or  without  
ribavirin.  Subjects  may  be  
treatment-naïve  or 
treatment experienced with pegylated-interferon based regimens excluding 
regimens with direct-acting antiviral agents. 
Investigational 
Product 
Administration 
VIEKIRA  PAK (ombitasvir,  paritaprevir/r,  dasubuvir)VIEKIRA  PAK  is 
ombitasvir, paritaprevir, ritonavir fixed dose combination tablets copackaged 
with dasabuvir tablets.  
 
Ombitasvir, paritaprevir, ritonavir fixed dose combination tablet includes a 
hepatitis  C  virus  NS5A  
inhibitor (ombitasvir), a  hepatitis  C  virus  NS3/4A 
protease  inhibitor  (paritaprevir),  and  a  CYP3A  inhibitor  (ritonavir)  that 
inhibits  CYP3A  mediated  metabolism  of  paritaprevir,  thereby  providing 
increased  plasma  concentration  of  paritaprevir.  Dasabuvir  
is  a  hepatitis  C 
virus non-nucleoside NS5B palm polymerase inhibitor, which is supplied as 
separate tablets in the copackage. Both tablets are for oral administration.  
 
VIEKIRA PAK is dispensed in a monthly carton for a total of 28  days  of 
therapy.  Each  monthly  carton  contains  
four  weekly  cartons.  Each  weekly 
carton contains seven daily dose packs. Each child resistant daily dose pack 
contains four tablets: two 12.5/75/50 mg ombitasvir, paritaprevir, ritonavir

9. History of solid organ transplant 
10. Screening  laboratory  analyses  shows  any  of  the  following  abnormal 
laboratory results: 
• Glomerular  filtration  rate  <  30  mL/min  as  estimated  by  the 
Cockcroft-Gault equation 
• Hemoglobin  < 12 gram per deciliter for male 
• Hemoglobin  < 11 gram per deciliter for female 
11. Evidence of cirrhosis, documented by one of the following:  
• Liver biopsy histologic diagnosis: Metavir Score  > 3 (includes 3 - 4 
or 3/4) or Ishak score  > 4  
• In the absence of liver biopsy: a FibroScan score  > 12.5 kPa 
• In the absence of a FibroScan: an APRI score > 1.5 
• In  
the judgment  of the investigator  clinical findings are  consistent 
with cirrhosis. 
In general, a non-cirrhotic result from a Fibroscan will 
supersede evidence of cirrhosis based on APRI and a liver biopsy not 
showing cirrhosis will supersede both Fibroscan and APRI 
12. History  of  liver  decompensation:  ascites  noted  on  a  physical  exam, 
imaging or other test; variceal bleeding; hepatic encephalopathy 
13. Confirmed presence of hepatocellular carcinoma indicated on computed 
tomography, magnetic resonance, or other imaging techniques within 3 
months prior to screening 
14. HCV genotype performed during screening indicates infection with any 
genotype other than genotype 1 
15. Recent history of drug or alcohol abuse that could, in the opinion of the 
investigator, affect adherence to the study protocol 
Study Endpoint 
The primary efficacy endpoint is to assess SVR12 in two subgroups of HCV 
(genotype 1a or 1b). The simple percentage of subjects achieving SVR12 will 
be calculated and a two-sided 95% confidence interval of the percentage will 
be computed based on Wilson
's score method. We cannot know a priori how 
the  200  patients  will  be  split  
into  
the  
two  subgroups,  but  we  expect  each 
group to have approximately 100 patients (presumably between 80 and 120). 
Assuming  a  subgroup  size  of  100  each,  the  lower  bound  of  the  95% 
confidence interval will be within 7 percentage points of the observed SVR12 
rate. 
Once the groups are fixed, the actual lower bound of the 95% confidence 
interval can be computed. 
 
The observed SVR12 rate and confidence interval will be discussed in the 
context of results from randomized clinical trials, such as the SAPPHIRE-

Statistical Methods 
This  is  an  open  label,  non-randomized,  study  with  two  study  arms. 
Descriptive  statistics  will  be  used  to  describe  the  observed  sustained 
virological response rate and patient adherence to the treatment regimen. The 
primary  analysis,  to  evaluate  SVR12,  will  occur  after  all  subjects  have 
completed or prematurely discontinued the study. 
 
The  intent-to-treat  population  will  consist  of  all  enrolled  subjects  in  this 
study. The primary efficacy analysis on clinical outcomes will be performed 
on all subjects in the intent-to-treat population. The modified intent-to-treat 
population will include all who receive at least one dose of study drug.  
No  data  will  be  imputed  for  any  efficacy  or  safety  analyses  except  for 
analyses of the HCV RNA endpoints.  
 
HCV  RNA  values  will  be  selected  for  the  SVR12 analysis  based  on  the 
defined visit. The visit window for analysis of SVR4 is post-treatment days 
2-56, and the visit window for analysis of SVR12 is post-treatment days 57-
168.  The latest available value within each window will be used to define 
the SVR 4 or SVR12 result.

BACKGROUND AND HYPOTHESIS    
  
  
 
Hepatitis C viral (HCV) infection is a global health problem. 170 million individuals are chronically 
infected worldwide and at risk of developing liver cirrhosis, hepatocellular carcinoma, or both.[1] 
Cirrhosis develops after prolonged hepatitis C virus infection.
[2] Complications of cirrhosis include 
hepatic decompensation (ascites; encephalopathy; variceal hemorrhage; hepato-renal syndrome or 
hepatic synthetic dysfunction) and hepatocellular carcinoma, which ensues at a rate of about 3% 
per year.
[3-6] Without liver transplantation, decompensated cirrhosis leads to death in 50% to 72% 
of patients after 5 years.
[7] As a result of the high prevalence of hepatitis C virus (HCV) infection 
and resultant complications, HCV is the leading indication for liver transplantation in the United 
States and the world as a whole.
[8]  
 
Treatment of hepatitis C virus-infected patients could reduce the risk of cirrhosis, decompensation, 
cancer,  and liver-related  deaths. Among  patients treated with pegylated interferon  and  
ribavirin 
therapy
, achieving a sustained virologic response (SVR) was associated with significant reduction 
in all-cause death compared to subjects who did not achieve sustained virologic response (5-year 
mortality rate in HCV genoty
pe 1-infected patients: 6.7% versus 14.4%, respectively).
[9]   
 
In  addition,  the  5-year  occurrence  of  
the  composite  clinical  events of  death, liver  failure,  and 
hepatocellular carcinoma were  significantly  lower  in hepatitis C  virus-infected  patients with 
advanced  fibrosis or cirrhosis  who achieved sustained  virologic  
response versus those without 
sustained  virologic  response  (9.2%  versus  28.2%,  respectively).
[10]  Patients with sustained 
virologic response  
following treatment with pegylated  
interferon with or  without ribavirin have 
also  shown improvement  in  liver  histology  and  a  reduction  in liver-related  death  in  several 
studies.
[11-13] 
 
Moreover,  patients with  compensated  cirrhosis who achieve sustained  virologic  response 
essentially eliminate their subsequent risk of decompensation, may achieve histologic regression, 
and decrease their risk of hepatocellular carcinoma by two-thirds.
[14-16] In patients with advanced 
fibrosis and  cirrhosis,  viral  suppression by  more  than  4  logs10 with  pegylated  interferon  and 
ribavirin was associated with marked reduction in death/liver transplantation, and in liver-related 
morbidity and death.[17] 
 
Combinations of direct-acting antiviral (DAA) agents targeting different steps of viral replication 
have the potential to significantly  
improve hepatitis C virus treatment,  compared to the current 
interferon-containing  regimens  for HCV genotype  1  infection.  Combination  DAA  allows  for 
increased/sustained virologic response rates, elimination of interferon as a component of therapy
, 
increased safety, and tolerability of treatment, shortened duration of therapy and simplifying the 
treatment algorithm. 
 
Wider  application  of direct-acting  antiviral  agent  
therapy and  better  
responses with  combination 
direct-acting antiviral agent regimen(s) could significantly reduce the public health burden of this 
disease.

's  interferon-free  regimen  for  the  treatment  of  chronic hepatitis  C  virus  genotype  1 
infection includes three direct-acting antiviral agents targeting different steps in hepatitis C virus

replication: ABT-450 is a nonstructural protein 3/nonstructural protein 4A (NS3/NS4A) protease 
inhibitor co-administered with a pharmacokinetic (PK) enhancer, ritonavir (ABT-450/r); an NS5A

The  three  direct-acting  antiviral  (3-DAA)  agents  regimen  has  been  studied  with  and without 
ribavirin in over 2,300 patients in Phase 3 trials across a variety of patient populations including 
those with compensated cirrhosis. Based on Phase 3 data, the regimen with or without ribavirin 
appears to be safe, well tolerated, and efficacious in treatment-naïve and treatment-experienced 
hepatitis C virus genotype 1-infected subjects including those  with compensated cirrhosis. The 
overall efficacy results (intent-to-treat) from the Phase 3 studies are listed in Table 1.

1.1 Phase 3 Placebo-Controlled Studies: SAPPHIRE-I and SAPPHIRE-II  
Study  SAPPHIRE-I  and SAPPHIRE-II  are  randomized,  placebo-controlled  studies  that 
assessed the safety and efficacy of 12 weeks of therapy with three direct-acting antiviral (3-
DAA)  agents  and  ribavirin  
in  hepatitis  C  virus  (HCV)  genotype  1-infected  
treatment-naïve 
subjects (Study SAPPHIRE-I) and prior pegylated-interferon/ribavirin non-responders (Study 
SAPPHIRE-II) without cirrhosis. Subjects received 3-DAA agents and ribavirin (RBV) for 12 
weeks of treatment. Subjects randomized to the placebo arm received placebo for 12 weeks, 
after  which  they  received  open-label  3-DAA  agents  and  RBV  for  12  weeks.  In  Study 
SAPPHIRE-I 631 subjects were randomized and received at least one dose of study drug, of 
which 67.7% had HCV  genotype 1a  and 32.3%  had  HCV  genotype 1b.  The SVR12 rate  
for 
treatment-naïve  subjects  receiving  3-DAA  agents  and  ribavirin  for  12  weeks  was  96.2%. 
Virologic  failure  was  noted  in  7/322  (2.2%)  genotype  1a  subjects  (on  treatment  virologic 
failure: n = 1; relapse: n = 6) and 1/151 (0.7%) genotype 1b subjects (relapse).  
 
In Study SAPHIRE-II, a total of 394 subjects were randomized and received at least one dose 
of  study  drug,  of  which  58.4%  had  hepatitis  C  virus  
(HCV)  genotype  1a,  41.4%  had  HCV 
genotype  1b,  49.0%  were  prior  pegylated-interferon/ribavirin  null  responders,  21.9/%  were 
prior  pegylated-interferon/ribavirin  partial  responders,  and  29.2%  were  prior  pegylated-
interferon/ribavirin  relapsers.  The  SVR
12 rate  for  treatment-experienced  subjects  receiving 
three direct-acting antiviral (3-DAA) agents and ribavirin for 12 weeks was 96.3%. Virologic 
failure (all relapse) was noted in 5/173 (2.9%) genotype 1a subjects and 2/123 (1.6%) genotype 
1b subjects.  
1.2 
Phase 3 Regimen-Controlled Studies: (3DAA  ± RBV): Studies PEARL-II, 
PEARL-III, PEARL-IV, and M14-002  
Studies PEARL-II, PEARL-III, and PEARL-IV are randomized, regimen-controlled trials that 
assessed  
the  safety  and  efficacy  of  12  weeks  of  
treatment  with  
three  direct-acting  antiviral 
agents  with  or  without  ribavirin.  Studies  PEARL-III  and  PEARL-IV  are  ribavirin  placebo-
controlled studies, while Study PEARL-II is an open-label study. The patient population was 
different in each of the three studies. Study PEARL-II enrolled genotype 1b-infected subjects 
with prior non-response to pegylated-interferon/ribavirin, Study PEARL-III enrolled genotype 
1b-infected subjects who were treatment-naïve, and Study PEARL-IV enrolled genotype 1a-
infected subjects who were treatment-naïve. All three studies excluded subjects with cirrhosis.  
In Study PEARL-II, a total of 186 subjects were randomized and received at least one dose of 
study  drug,  of  which  34.9%  were  prior  pegylated-interferon/ribavirin  (pegIFN/RBV)  null 
responders, 28.5% were prior pegIFN/RBV partial responders, and 36.6% were pegIFN/RBV 
relapsers. The SVR
12 rates were 96.6% in the three direct-acting agents with ribavirin arm and 
100% in the three direct-acting antiviral agents without ribavirin arm. The difference in SVR
12 
rates between the two regimens met the protocol-specified criteria for noninferiority. Hence, 
the  three  direct-acting  antivirals  (3-DAA)  regimen  without  ribavirin  demonstrated 
noninferiority  compared  to  the  (3-DAA)  agents  and  ribavirin.  No  subject  in  either  arm 
experienced on treatment virologic failure or post-treatment relapse.

In the PEARL-III study, 419 subjects were randomized and received at least one dose of study 
drug.  The  SVR12 rates  for  treatment-naïve  subjects  with  HCV  genotype  1b-infection,  who 
received  either  3-DAA  with,  or  without  ribavirin  for  12  weeks  were  99.5%  and  99.0%, 
respectively. The difference in SVR
12 rates between the two regimens in this study also met the 
protocol-specified criteria for noninferiority. One of the 419 treated subjects in the three direct-
acting antiviral agents and ribavirin arm experienced on-treatment virologic failure. 
 
In Study M14-002, 305 subjects were randomized and received at least one dose of study drug. 
The SVR12 rates for treatment-naïve subjects with HCV genotype 1a-infection who received 
three  direct-acting  antiviral  agents  either  with  or  without  ribavirin  for  12  weeks  in  Study 
PEARL-IV were 97.0% and 90.2%, respectively. The SVR
12 rate in the 3-DAA arm did not 
achieve noninferiority to the 3-DAA and ribavirin arm. Virologic failure was noted in 2/100 
(2.0%) subjects (on treatment virologic failure: n = 1; relapse: n = 1) in the ribavirin-containing 
regimen and 16/205 (7.8%) subjects (on treatment virologic failure: n = 6; relapse: n = 10) in 
the ribavirin-free regimen. The difference between arms demonstrates that ribavirin contributes 
to the efficacy in genotype 1a-infected patients and suggests that three direct-acting antiviral 
agents and ribavirin is the optimal regimen for these patients. 
1.3 
Phase 3 Study in Cirrhotics:  Study TURQUOISE-II 
Study  TURQUOISE-II  is  a  randomized,  multicenter,  open-label  trial  in  treatment-naïve 
subjects  or  subjects  previously  treated  with  pegylated-interferon/ribavirin  with  chronic 
hepatitis C virus genotype 1-infection with compensated cirrhosis (Child-Pugh A, score l< 6). 
The  
three  direct-acting  antiviral  agents  and  
ribavirin  were  administered  
for  either  12  or  24 
weeks of treatment. 
 
A total of 380 subjects were randomized and received at least one dose of study drug, of which 
68.7% had hepatitis C virus genotype 1a, 31.3% had hepatitis C virus genotype 1b, 42.1% were 
treatment-naïve,  36.1%  were  prior  pegylated-interferon/ribavirin  (pegIFN/RBV)  null 
responders,  8.2%  were  prior  pegIFN/RBV  partial  responders,  and  13.7%  were  prior 
pegIFN/RBV relapsers. 
 
The  SVR12 rates  for  subjects  with  compensated  cirrhosis treated  with  three  direct-acting 
antiviral  agents  and  ribavirin  for  12  or  24  weeks  were  91.8%  and  95.9%,  respectively. 
Virologic failure was noted in 13/208 (6.3%) subjects (on treatment virologic failure: n = 1; 
relapse:  n  =  12)  receiving  the  12  week  regimen  and  4/172  (2.3%)  subjects  (on  treatment 
virologic failure: n = 3; relapse: n = 1) receiving the 24 week regimen. 
 
Analyses of subgroups suggest that the overall difference in SVR12 rates was driven largely by 
a  lower  SVR
12 rate  among  genotype  1a  prior  null  responders  who  received  12  weeks  of 
treatment,  while  other  subgroups  had  comparable  
response  
rates  when  
treated  
for  12  or  24 
weeks.

Integrated Safety Results 
A summary of treatment-emergent adverse events from the combined analyses of data from 
the Phase 3 studies is presented in Table 2. A majority of subjects experienced at least one 
event, but most subjects experienced events that were mild in severity. Rates of severe adverse 
events and adverse events leading to discontinuation were low across studies but numerically 
higher in the study of subjects with cirrhosis.

followed by resolution was similar and few were symptomatic (jaundice). Rates of ≥ Grade 2 
hemoglobin reductions were 6% among subjects without cirrhosis who received the 3-DAA

received  the  3-DAA  and  ribavirin  regimen  for  12  and  24  weeks,  respectively.  Grade  3 
hemoglobin values were rare. The decline in hemoglobin was largely managed with ribavirin 
dose  reductions;  use  of  hematologic  growth  factors  and  blood  transfusion  were  rare.  The

anemia reported in the clinical trials was primarily observed when the 3-DAA regimen was

arms  and  were  evaluated  by  an  external  hepatic  panel.  The  serum  (ALT)  elevations  were 
asymptomatic, usually occurred within the first four weeks of treatment and typically declined 
with ongoing treatment. A disproportionate number of the cases were in women on concurrent 
systemic  estrogen-containing  therapy  (i.e.  contraceptives  or  hormone  replacement)  and 
discontinuation of the hormonal therapy with continuation or brief interruption of the direct-
acting  antiviral  regimen  led  to  resolution  in  ALT  elevation.  Concomitant  use  of  systemic 
estrogen-containing  medications  
is  a  
risk  
factor  
for  
these  post-baseline  elevations  
in  serum 
alanine aminotransferase. No serum ALT elevations > 5 times ULN were observed in subjects 
receiving progestin only, or in subjects receiving topical vaginal estrogen preparations. Among 
the cases of serum ALT elevation, considered related to the direct-acting antiviral regimen, 
none resulted in hepatic dysfunction and they generally resolved or improved with ongoing 
treatment. All cases had resolved completely in the post-treatment follow-up. 
 
ABT-450/ritonavir,  ABT-267  
(ombitasvir)  
(and  
its  major,  
inactive  human  metabolites)  and 
ABT-333 (dasabuvir) had no effects on embryo-fetal development in rodent and/or non-rodent 
species at maximal feasible exposures that provided area under the curve (AUC) multiples at 
least  4-fold  higher  than  exposures  at  the  recommended  clinical  doses.  Clinical  studies  in 
women who are pregnant have not been conducted. 
 
In  summary,  the  three  direct-acting  antiviral  (3-DAA)  agents  regimen,  with  or  without 
ribavirin, was well tolerated with a low discontinuation rate. Adverse events were typically 
mild, and many of the adverse events and laboratory abnormalities observed were attributable 
to the presence of ribavirin. 
 
Transient, asymptomatic serum alanine aminotransferase (ALT) elevations were observed at a 
low rate, were not associated with hepatic dysfunction, and generally resolved with ongoing 
treatment. 
1.5 
Study Risks versus Benefits 
ABT-450/ritonavir, ABT-267 (ombitasvir) and ABT-333 (dasabuvir) with or without ribavirin 
have been well tolerated in the Phase 3 studies. Adverse events that are known, and those not 
previously described, may occur with the direct-acting antivirals or ribavirin as detailed in the 
informed  consent  for  this  study.  In  addition,  subjects  may  experience  inconvenience  or 
discomfort related to the study visits or study procedures.  
 
Risks associated with ABT-450/ritonavir/ABT-267 (ombitasvir) and ABT-333 (dasabuvir) co-
administered  with  or  without  
ribavirin,  
including  
the  
risks  of  
toxicity  and  virologic  
failure, 
appear  limited  and  manageable  based  on  the  results  from  the  Phase  3  studies.  Given  the 
potential high rate of cure in hepatitis C virus genotype 1-infected subjects, the risk-benefit 
comparison is favorable.

This study will evaluate outcomes with ABT-450/ritonavir/ABT-267 (ombitasvir) and ABT-
333  (dasabuvir)  with  or  without  ribavirin  for  treatment-naïve  and  interferon/ribavirin 
treatment-experienced  adults  with  chronic  HCV  genotype  1-infection without cirrhosis in a 
real world setting. A non-cirrhotic population will be evaluated as this is a group that is not 
considered of highest priority according to current national practice guidelines and therefore, 
largely unstudied in a large real world population. 
 
Until  recently,  the  treatment  of  genotype  1  chronic  HCV  infection  involved  complicated 
interferon-containing regimens associated with many side effects. Due to adverse events and 
patient dropout, outcomes in real world settings during and after treatment with these regimens 
have been inferior to those seen in controlled clinical trials. The cure rate (sustained virological 
response) and the effectiveness of treatment has been reported to be low in real world settings 
using interferon-based treatment regimens. In a Veterans Administration study by Kramer et 
al, only 39.9% of genotype 1 patients who completed treatment and only 23.6% of those who 
initiated  treatment  achieved  sustained  virological  response.  Importantly,  treatment 
effectiveness  (defined  as  the  proportion  of  the  viremic  cohort  who  achieved  sustained 
virological response) was very low at only 3.5%.[18]  
FDA Approval 
On December 19, 2014, the FDA Approved ABT-450/ritonavir, ABT-267 (ombitasvir) and 
ABT-333 (dasabuvir) 
as VIEKIRA PAK™ (ombitasvir, paritaprevir, and ritonavir tablets, 12.5 
mg/  75  mg/  50  mg;  dasabuvir tablets,  250  mg),  co-packaged  for  oral  use  with  or  without 
ribavirin  for  the  treatment  of  patients  with  genotype  1  chronic  hepatitis  C  virus  (HCV) 
infection including those with compensated cirrhosis. 
1.6 
Hypothesis 
Since the new treatment regimens do not cause the adverse events associated with the prior 
therapy, our hypothesis is that treatment with the VIEKIRA PAK (ombitasvir, paritaprevir/r, 
dasubuvir) with or without ribavirin will result in excellent outcomes in the real world setting 
and that the outcomes will be similar to those seen in the registration trials.

STUDY DESIGN 
3.1 Description of the Study 
This  is  a  Phase  IV,  open-label,  multi-center  study  to  evaluate  the  real  world  sustained 
virological response rate, subject adherence, and subject reported outcomes during and after 
treatment of non-cirrhotic genotype 1 chronic hepatitis C subjects aged 18  years and older, 
with the AbbVie 3 direct-acting antiviral (3-DAA) regimen of VIEKIRA PAK (ombitasvir, 
paritaprevir/r,  dasubuvir),  with  or  without  ribavirin. Subjects may  be  treatment-naïve  or 
treatment  experienced  with  pegylated-interferon  based  regimens  excluding  regimens  with 
direct-acting antiviral agents.   
 
The study will be conducted at multiple KPSC Medical Centers and will screen approximately 
275 subjects with an estimated 33% screen failure rate to enroll 200 subjects.      
3.2 Subject Population 
Subjects will be considered treatment-naïve if they have never received any antiviral treatment 
for HCV infection. 
 
Subjects will be considered treatment-experienced if they have received prior interferon-based 
therapy (including interferon or pegylated-interferon monotherapy; interferon and ribavirin; or 
pegylated-interferon  and  
ribavirin).  Treatment-experienced subjects with  prior  use  of  HCV 
DAA(s) are excluded from study participation. 
 
Subjects with documentation available to classify prior response to interferon and ribavirin, or 
pegylated-interferon and ribavirin treatment will be categorized as one of the following:
 
• Null-responder: did not achieve a 1 log10 IU/mL reduction in HCV RNA by week 4 or a 
2 log10 IU/mL reduction in HCV RNA by week 12 during a prior interferon and ribavirin, 
or pegylated-interferon and ribavirin treatment course 
• Partial-responder: achieved at least a 2 log
10 IU/mL reduction in HCV RNA by week 12 
during  a  prior  interferon  and  ribavirin  or  pegylated-interferon  and  ribavirin  treatment 
course, but failed to achieve HCV RNA undetectable at the end of treatment 
• Relapser: achieved undetectable HCV RNA at end of a prior interferon and ribavirin or 
pegylated-interferon  and  ribavirin  treatment  course,  but  HCV  RNA  was  detectable 
following therapy completion 
Subjects  with  a  less  well-characterized  IFN-based  treatment  experience,  including  those 
subjects with incomplete HCV RNA and treatment date documentation, will be categorized as 
one of the following:

• Relapse/breakthrough: achieved  at  least  one  documented  result  of  HCV  RNA 
undetectable during a prior IFN and RBV ribavirin, or pegIFN and RBV treatment course 
• Non-responder: did not achieve a documented result of HCV RNA undetectable or HCV 
RNA was detected at the end of treatment during a prior IFN and RBV, or pegIFN and 
RBV  
treatment  course  with  
insufficient  data  available  
to  categorize  as  a  breakthrough, 
partial or null responder 
• Interferon intolerant:  did not meet any of the above definitions of treatment-failure and 
discontinued IFN and RBV, or pegIFN and RBV therapy due to IFN intolerability 
• Interferon experienced-other:  Includes IFN, or pegIFN and RBV monotherapy; IFN and 
RBV,  or  pegIFN  and  RBV  experienced  subjects;  Includes  subjects  who  do  not  have 
adequate  documentation  of  response.  Subjects  receiving  interferon  or  peginterferon 
monotherapy must be categorized as 
'Interferon experienced-other
'.

commonly reported adverse reactions (greater than or equal to 5% of subjects) were nausea, 
pruritus and insomnia. Refer to the VIEKIRA PAK Package Insert for more information. 
4.6.2 
Ribavirin 
The primary toxicity of ribavirin is hemolytic anemia. The anemia associated with ribavirin 
therapy may result in worsening of cardiac disease that has led to fatal and nonfatal myocardial 
infarctions.  Patients  with  a  history  of  significant  or  unstable  cardiac  disease  should  not  be 
treated with ribavirin. 
 
Significant teratogenic and embryocidal effects have been demonstrated in all animal species 
exposed to ribavirin. In addition, ribavirin has a multiple-dose half-life of 12 days, and so it 
may persist in nonplasma compartments for as long as 6 months. Therefore, ribavirin therapy 
is contraindicated in women, who are pregnant and in the male partners of women who are 
pregnant. Extreme care must be taken to avoid pregnancy during therapy and for 6 months 
after completion of treatment in both female patients and in female partners of male patients 
who are taking ribavirin therapy. At least two reliable forms of effective contraception must 
be utilized during treatment and during the 6-month post-treatment follow-up period. 
Refer to the Ribavirin Package Insert for more information. 
4.7 Prohibited Medication 
Estrogen-containing  hormonal  contraceptives,  
including  oral,  
injectable,  
implantable,  patch 
and ring varieties, may not be used during study drug treatment.

cytochrome P450 2C8 (CYP2C8) or strong inhibitors of CYP2C8 within 2 weeks of the 
respective medication/supplement prior to initial dose of study drug (see Table 5). 
6. Clinically  significant  abnormalities  or  co-morbidities,  other  
than  HCV  
infection  
that  
in 
opinion of the investigator makes subject unsuitable for this study or drug regimen 
7. Current enrollment in another interventional clinical study or prior or current use of any 
investigational  or  commercially  available  anti-HCV  agents  other  than  interferon  or 
ribavirin including previous exposure to ABT450 (paritaprevir), ABT-267 (ombitasvir) or 
ABT-333  (dasabuvir)  or  
receipt  of  any  
investigational  product  within  6  weeks  prior  
to 
study drug administration 
8. Prior treatment of chronic HCV infection with a direct acting antiviral agent(s): telaprevir, 
boceprevir, sofosbuvir, simeprevir, or other direct acting antiviral 
9. History of solid organ transplant 
10. Screening laboratory analyses shows any of the following abnormal laboratory results: 
• Glomerular filtration rate < 30 mL/min as estimated by the Cockcroft-Gault equation19 
• Hemoglobin < 12 gram per deciliter for male 
• Hemoglobin < 11 gram per deciliter for female 
11. Evidence of cirrhosis, documented by one of the following:  
• Liver biopsy histologic diagnosis: Metavir Score > 3 (includes 3 - 4 or 3/4) or Ishak 
score > 4  
• In the absence of liver biopsy: a FibroScan score > 12.5 kPa 
• In the absence of a FibroScan: an APRI score > 1.5 
• In the judgment of the investigator clinical findings  are  consistent with cirrhosis.  
In 
general,  a non-cirrhotic result from a Fibroscan will supersede evidence  of cirrhosis 
based on APRI and a liver biopsy not showing cirrhosis will superseded both Fibroscan 
and APRI. 
12. History of liver decompensation: ascites noted on a physical exam, imaging or other test; 
variceal bleeding; hepatic encephalopathy

6.2.4.3 Unscheduled Visits and Labs  
Unscheduled visits and labs may be done as determined by the investigator to protect the safety 
of the subject, such as in the case of AEs.  
6.2.4.4 Unscheduled Drug Dispensing 
Unscheduled drug dispensing to prevent treatment interruption requires prior approval from 
the Sponsor-Investigator or designee. 
6.3 
Subject Discontinuation 
6.3.1 
Subject Initiated Discontinuation 
Each subject has the right to withdraw from the study at any time for any reason. Subjects who 
discontinue from the study regardless of cause should be encouraged to complete the Early 
Termination  Visit  within  14  days  of  the  last  treatment dose. Ideally  for  study  drug 
discontinuation, this should occur on the day of study drug discontinuation, and prior to the 
initiation of any other anti-hepatitis C virus therapy. However, these procedures should not 
interfere with the initiation of any new 
treatments or therapeutic modalities that the investigator 
feels are necessary to treat the subject
's condition.   
 
In the event that subject is unable to complete the visit but willing to provide survival status, 
the study site staff should contact the patient within 14 days of the last study dose to collect 
the information. 
 
Following discontinuation of study drug, the subject will  be  
treated in accordance with the 
investigator
's  best  clinical  judgment.  The  last  dose  of  any  study  drug  and  reason  for 
discontinuation from the treatment period will be recorded in the case report form. 
 
Withdrawal of consent for the study will be  documented  
in the subject’s study records and 
reported to the PI and/or designee.  
6.3.2 
Investigator Initiated Discontinuation 
The investigator may also discontinue a subject from the study at any time for the following 
reasons: 
•  Subject or subject’s partner experiences AE or toxicity from the study drug that warrants 
discontinuation, or 
•  Subject is noncompliant (e.g. missed treatment doses, or missed visits) with the protocol, 
or 
• If  a  subject  has  an  ongoing AE or  an  unresolved  
laboratory  result  
that  
is  significantly 
outside of the reference range at the time of study drug discontinuation, the investigator 
will attempt to provide follow-up until a satisfactory clinical resolution of the laboratory 
result or AE is resolved.

Page 38 of 54 
 
6.3.3 
Discontinuation of Subjects Meeting Virologic Failure Criteria 
The following criteria will be considered evidence of virologic failure: 
• Confirmed  
increase  from  nadir  
in  HCV  RNA,  defined  as  
two  consecutive  HCV  RNA 
measurements > 1 log10 IU/mL above nadir, at any time point during treatment 
• Confirmed HCV RNA ≥ lower limit of quantification, defined as two consecutive HCV 
RNA measurements ≥ lower limit of quantification, at any point after HCV RNA less than 
lower limit of quantification 
Confirmatory testing for the above criteria should be completed. Subjects receiving study drug 
treatment should remain on treatment until the virologic failure has been confirmed.  
 If  any  of  
the  above  criteria  are  confirmed  
for  subjects  during  study  drug  
treatment,  
the 
subject will discontinue treatment.  
 If any of the above criteria are confirmed for subjects during the post-treatment phase of 
the study, the subject will be discontinued from the study. 
6.3.4 
Pregnancy 
In the  event that a positive result is  obtained on a pregnancy test for  a subject or a subject 
reports  becoming  pregnant  during  the  treatment  period,  the  administration  of  ribavirin  (if 
applicable)  to  that  subject  must  be  discontinued  immediately. The  investigator  is  also 
encouraged to report the pregnancy information to the voluntary ribavirin pregnancy registry, 
if applicable. 
 
Direct-acting antiviral agents may be continued at the Sponsor-investigator
's discretion after 
discussion with the subject, if the benefit of continuing direct acting antiviral agents is felt to 
outweigh the potential risk. Subjects will be monitored for sustained virological response in 
the post-treatment period per protocol.  
7 
DATA COLLECTION AND MONITORING 
7.1 Data Management and Record Keeping 
The data will be collected and reported on paper case report forms and/or in electronic medical 
record. Each site will be responsible for data entry into system. In the event of discrepant data, 
research  personnel  at  each  site  will  resolve items. KPSC will  be  responsible  for  the  data 
management of this study, including quality checking of the data by conducting an internal 
audit review. 
7.2 Data Monitoring Plan

window for analysis of SVR12 is post-treatment days 57-168. 
 The latest available value within 
each window will be used to define the SVR 4 or SVR12 result.  
8.1 Demographics 
Demographics and baseline characteristics will be summarized for all subjects in the intent to 
treat  population.  Demographics  
include  age,  weight,  height,  and  body  mass  
index,  and  
the 
frequency of gender, race, and ethnicity.  
 
Baseline characteristics will include:  
• HCV  genotype  1  subtype  (1a,  1b);  interferon  treatment  history  (treatment-naïve 
[interferon-eligible, interferon-ineligible] or interferon-based treatment experienced [null 
responder,  partial  responder,  relapse,  prior  relapse/breakthrough,  prior  nonresponder, 
interferon intolerant and interferon experienced-other]);  
• Baseline HCV RNA levels [(continuous) ≤ 800,000 IU/ or > 800,000 IU/mL], baseline.  
 
Summary statistics (number, mean, median, standard deviation and range) will be generated 
for continuous variables for example, age, and body mass index. The number and percentage 
of subjects will be presented for categorical variables for example, gender, and race. 
8.2 Safety Outcome Measures 
The  following  safety  evaluations  will  be  analyzed  during  
the  study: AEs  monitoring,  and 
laboratory test assessments. Potential AEs that will be captured include those most commonly 
reported  in  the  registration  trials  including  headache,  fatigue,  nausea,  pruritus,  insomnia, 
diarrhea, asthenia, rash, cough, irritability, anemia and dyspnea.  
 
All subjects who receive at least one dose of study drug will be included in the safety analyses. 
8.3 
Efficacy Analysis 
The primary efficacy analysis on clinical outcomes will be performed on all subjects in the 
intent to treat population. All other efficacy analyses will be performed on the modified intent 
to treat population 
8.3.1 
Primary Efficacy Endpoint 
The primary efficacy endpoint is to assess SVR12 in two subgroups of HCV (genotype 1a or 
1b). The simple percentage of subjects achieving SVR12 will be calculated and a two-sided 
95% confidence interval of the percentage will be computed based on Wilson
's score method. 
We cannot know a priori how the 200 patients will be split into the two subgroups, but we 
expect  each  group  
to  have  approximately  100 patients (presumably  between  80  and  120). 
Assuming a subgroup size of 100 each, the lower bound of the 95% confidence interval will

Page 41 of 54 
 
be within 7 percentage points of the observed SVR12 rate. 
Once the groups are fixed, the actual 
lower bound of the 95% confidence interval can be computed. 
 
The observed SVR12 rate and confidence interval will be discussed in the context of results 
from randomized clinical trials, such as the SAPPHIRE-I/II trials and PEARL-II/III/IV trials 
described in the Background section.  While formal statistical inference comparing results of 
this study to those of the randomized clinical trials will not be conducted, the point estimates 
and confidence intervals will be compared to assess the degree to which results from the real 
world setting are similar to or different from those in the randomized clinical trial setting. 
Results by prior treatment experience and response may be summarized if appropriate, based 
on the number of subjects enrolled in each subgroup. No subgroup sample size targets have 
been established. 
8.3.2 
Secondary Efficacy Endpoint 
The secondary efficacy endpoints are: 
• To assess SVR4. The simple percentage of subjects achieving SVR4 will be calculated and 
a two-sided 95% confidence interval of the percentage will be computed based on Wilson
's 
score method. 
• Patient adherence with the VIEKIRA PAK regimen will be evaluated by review of study 
drug  
returned for drug reconciliation and/or compilation of patient reported compliance 
information.

ASSESSMENT OF SAFETY 
9.1 Safety Parameter and Definitions 
9.1.1 
Adverse Event (AE) 
An  adverse  event  
(AE)  
is  any  undesirable  experience  associated  with  
the  use  of  a  medical 
product in a subject and includes the following: 
• AE not  previously  observed  in  the  subject  during  the  protocol-specified AE reporting 
period, limited to signs or symptoms associated with Genotype 1 Chronic Hepatitis C and 
effects of study drug 
• Complications that occur as a result of protocol-mandated activities 
• AEs that occur prior to study treatment assignment that are related to a protocol-mandated 
activity 
• Pre-existing medical conditions determined by investigator to have worsened in frequency 
or severity during the protocol-specified AE reporting period 
9.1.2 
Serious Adverse Event (SAE) 
A Serious Adverse Event (SAE) is any adverse event that is any of the following: 
• Fatal

Page 42 of 54 
 
• Life-threatening 
• Requires initial or prolonged hospitalization 
• Disability or permanent damage 
• A  congenital  anomaly/birth  defect  in  a  neonate/infant  that  is  suspect  
to  exposure  to  a 
medical product prior to conception or during pregnancy 
• A significant medical event determined by the investigator that may jeopardize the subject 
or may require medical or surgical intervention to prevent one of the outcomes listed above 
9.1.3 
Clinical Laboratory Abnormalities and Other Abnormal Assessments 
Laboratory  abnormalities  without  clinical  significance  are  not  recorded  as  AEs  or  SAEs, 
However, in the event that the abnormalities require medical or surgical intervention, or lead 
to interruption, modification or discontinuation of either of the investigational drug, they must 
be recorded as an AE, and if applicable as an SAE. When reporting the AE, the event should 
be based on the syndrome or diagnosis, and not the lab result.  
9.2 Methods and Timing for Capturing Safety Parameters 
The investigator is responsible for ensuring that all potential AEs (defined in Section 9.1.1) or 
SAEs (defined in Section 9.1.2) that occurred after subject provides written informed consent, 
but prior to initiation of study medication that are caused by protocol-mandated interventions 
will be collected and reported.  
 
After initiation of study treatment, all AE and SAE probably related or possibly related to the 
study treatment or study-related procedures will be collected and reported until the end of study 
visit, or Early Termination.  
9.2.1 
Timing of Adverse Event (AE) Reporting 
All AEs  occurring  after  
the  
initiation  of  study  
treatment that  are considered expected,  and 
possibly or  definitely related  to  the  study  (e.g.  treatment)  must  be documented,  and 
subsequently  reported  to  the Sponsor-Investigator or  designee at  the  end  of  the  subject’s 
participation in the study.  
 
All AEs that are considered unanticipated, and possibly or definitely related to the study (e.g. 
treatment) must be reported to the Sponsor-Investigator or designee within 72 hours. 
 
All unanticipated SAEs considered possibly or definitely related to the study (e.g. treatment) 
must be reported to the Sponsor-Investigator or designee within 24 hours of discovery. 
 
Any AEs identified as occurring prior to the study treatment will be considered as part of the 
subject’s medical history.

9.2.1 
Reportable Adverse Event (AE) or Serious Adverse Event (SAE) 
All  
reportable AEs  or SAE will  be  
recorded  
in  source  documents  and  
reported  
to IRB per 
reporting guidelines. Additionally, any AEs that meet the criteria for MedWatch reporting will 
be submitted accordingly. 
9.2.2 
Assessment of Serious, Severity, Causality and Unexpectedness 
Investigators are required to assess all AEs occurring after the initiation of study treatment for 
seriousness, severity, and causality as defined below. 
 
Serious refers to events that pose a threat to a subject’s life or vital functions and is based on 
subject or event outcome or action criteria. An AE that does not meet any criteria for serious, 
as defined in Section 9.1.2 should be regarded as “non-serious” AE.  
 
Severity refers to intensity of an AE as “mild,” “moderate,” or “severe”:  
• Mild: Symptom(s) that do not interfere with subject’s usual social and functional activities 
• Moderate:  Symptom(s)  that  interfere  to  some  extent  with  subject’s  usual  social  and 
functional activities 
• Severe: Symptom(s) that interfere significantly with subject’s usual social and functional 
activities 
Causality refers to a reasonable possibility that the AE is related to the study medication or 
study-related procedure. If AE is not related to study medication or study-related procedure, 
investigators will assess the most likely cause of AE. 
 
Unexpected refers  
to  whether  or  not  
the AE is  described  as  a  
risk  
in  
the  package  
insert  or 
investigator’s brochure for the study drug(s), the protocol or in the informed consent form.
