1.1
Protocol Amendment:  Summary of Changes
The purpose of this amendment is to:
●
Update the treatment duration for subjects with GT1a infection and 
compensated cirrhosis (F4 fibrosis stage) from 12 to 24 weeks, with 12 weeks 
considered for some patients where consistent with the local label.
Rationale:  To align the treatment duration for these subjects with that 
recommended in the prescribing information of section of the approved local 
product labels in countries where the AbbVie product containing the regimen 
for this study (i.e., ABT-450/r/ABT-267 and ABT-333) has received marketing 
authorization.
●
Update Introduction to remove language detailing effects of 
ABT-450/ritonavir, ABT-267 (and it major, inactive human metabolites) and 
ABT-333 on embryo-fetal development.
Rationale:  Results of embryo-fetal toxicity studies are described in the locally 
approved labels and in the investigator brochures.
●
Update Introduction to refer investigators to locally approved labels for 
preclinical toxicology (including reproductive and development toxicity), 
metabolism, pharmacokinetics and drug-drug interactions in countries that 
have received marketing approval.
●
Clarify elevated ALT risk associated with ethinyl estradiol therapy in 
Section 3.0 Introduction; Integrated Safety Results.
Rationale:  AbbVie re-evaluated data on grade 3 or higher post-baseline 
serum ALT values in subjects and identified concurrent use of ethinyl estradiol 
as a risk factor for ALT elevations.  Concurrent use of estrogens other than 
ethinyl estradiol was not associated with an increased risk of grade 3+ ALT 
values, and therefore, there are no contraindications for these estrogen 
products that are commonly used in hormone replacement.
●
Clarify enrollment caps for cirrhotic subjects.
●
Update Contraindicated Medication list in Synopsis and Exclusion 3 (Table 6) 
to refer investigators to locally approved labels were AbbVie product 
containing the regimen for this study has been approved.

Rationale:  To align the contraindicated medication list with that 
recommended in the prescribing information section of the approved local 
product labels in countries where the AbbVie product containing the regimen 
for this study has received marketing authorization.
●
Update Schedule of Activities (Table 7) removing duplicate "Study Drug 
Returned for IRT Reconciliation" entry.
●
Update Schedule of Activities (Table 7, footnote "j.") and Section 5.3.1.1 to 
clarify urine pregnancy testing requirements for subjects on DAA regimen 
only.
●
Add AFP to the list of Clinical Laboratory Tests collected at the Screening 
Visit.
Rationale: To more fully characterize the subject's baseline laboratory status.
●
Update Table 12 to allow for RBV dose modifications in management of 
hemoglobin decreases per local label.
●
Update Section 9.1 to include submission of amendments to Regulatory 
Authority(ies) as applicable.
●
Update Table 4 (Baseline Fibrosis Stage) to correct administrative error for F4 
FibroScan range.
●
Add back-up Sponsor contact phone number to Title Page and Section 6.5.
An itemized list of all changes made to the protocol under this amendment can be found 
in Appendix D.

Protocol Title:  
An Open-Label, Multicenter Study to Evaluate Long-Term Outcomes With ABT-450/Ritonavir/
ABT-267 (ABT-450/r/ABT-267) and ABT-333 With or Without Ribavirin (RBV) in Adults With 
Genotype 1 Chronic Hepatitis C Virus (HCV) Infection (TOPAZ-I)
Objectives:  
The primary objective of this study is to evaluate the effect of response to treatment (assessed by SVR12
status) on the long-term progression of liver disease in adults with chronic HCV GT1 infection who 
received treatment with ABT-450/r/ABT-267 and ABT-333 with or without ribavirin, as measured by 
all-cause death, liver-related death, liver decompensation, liver transplantation, and hepatocellular 
carcinoma.
Secondary Objectives:
!
To evaluate the long-term progression of fibrosis by baseline fibrosis stage and sustained 
virologic response, as measured by change from baseline in liver stiffness measured by transient 
elastography (FibroScan®) when available, in adults with genotype 1 (GT1) chronic HCV 
infection who received treatment with ABT-450/r/ABT-267 and ABT-333 with or without 
ribavirin.
!
To evaluate the percentage of subjects achieving SVR12 with ABT-450/r/ABT-267 and 
ABT-333 with or without ribavirin in adults with GT1 chronic HCV infection.
Investigators:  
Multicenter, investigator information on file at AbbVie
Study Sites:  
Approximately 200 sites
Study Population:  
Adults at least 18 years of age, with GT1 chronic HCV infection, with or without compensated cirrhosis, 
who are treatment-naïve or IFN-based therapy treatment-experienced.
Number of Subjects to be Enrolled:  
Approximately 1650 subjects

Methodology:  
The TOPAZ studies are composed of 2 studies (TOPAZ-I [M14-423; to be conducted in non-US regions] 
and TOPAZ-II [Study M14-222; to be conducted in the US]) due to administrative reasons.  This study 
(TOPAZ-I) is a Phase 3b, open-label, multi-center study designed together with companion study 
TOPAZ-II, which shares the primary objective of evaluating the effect of SVR12 status on the long-term 
clinical outcomes in adults with GT1 chronic HCV infection with or without compensated cirrhosis, who 
are either treatment-naïve or IFN-based therapy (IFN or pegIFN monotherapy, IFN/RBV, or 
pegIFN/RBV) treatment-experienced.  In both studies, subjects will be treated with ABT-450/r/ABT-267 
and ABT-333 with or without ribavirin (RBV). 
Subjects meeting the eligibility criteria will be enrolled until approximately 1650 subjects have been 
enrolled at approximately 200 sites. 
The study will consist of a Screening Period, Treatment Period and a Post-Treatment Period. 
Treatment Period:  HCV GT1-infected subjects who are either treatment-naïve or IFN-based therapy 
treatment experienced will receive ABT-450/r/ABT-267 and ABT-333.  Subjects with HCV GT1a 
infection and all GT1-infected subjects with compensated cirrhosis will also receive RBV. 
The treatment duration will be 12 weeks for all subjects except HCV GT1a-infected subjects with 
compensated cirrhosis; these subjects will receive treatment for 24 weeks.  Treatment duration of 
12 weeks for HCV GT1a-infected subjects with compensated cirrhosis may be selected by the 
investigator where consistent with the local approved label, in countries where marketing authorization 
has been granted for the regimen included in this study.
HCV GT1a-infected subjects with compensated cirrhosis who were originally assigned to 12 weeks of 
treatment under a previous version of this protocol will be assigned to 24 weeks of treatment unless 1) the 
investigator determines that a 12-week duration of therapy is appropriate based on the approved local 
label; or 2) the subject has already completed the original study drug treatment and additional treatment 
cannot be initiated within 15 days of the date that the original treatment was completed.
Post-Treatment Period:  subjects who receive at least one dose of study drug will be followed for up to 
260 weeks.  At these visits subjects will be assessed for antiviral response, progression of liver fibrosis, 
and clinical outcomes, including all-cause death, liver-related death, occurrence of hepatocellular 
carcinoma, liver decompensation and liver transplantation.
The number of cirrhotic subjects (an equivalent Metavir score of F4) will be limited to less than or 
approximately equal to 400 subjects; the number of subjects enrolled without fibrosis or with portal 
fibrosis without septa (an equivalent Metavir score of F0 or F1 respectively) will be limited to 
1000 subjects.  In the absence of a qualifying liver biopsy, the equivalent Metavir score corresponding to 
the results of a screening FibroScan or FibroTest will be used to determine the fibrosis stage.

Duration of Treatment:  
Subjects will receive ABT-450/r/ABT-267 and ABT-333 with or without RBV for 12 or 24 weeks.
Criteria for Evaluation:
Efficacy:
Plasma HCV RNA (IU/mL) will be assessed at each Treatment and Post-Treatment Visit.  Clinical 
outcomes related to death and the liver will be assessed during treatment and post-treatment.
Patient Reported Outcomes (PROs):
During treatment and post-treatment, fatigue and general health related quality of life will be assessed 
using the short form 36 version 2 (SF-36v2) and Functional Assessment of Chronic Illness 
Therapy – Fatigue (FACIT–F) questionnaires.
Safety:
Safety and tolerability will be assessed by monitoring adverse events, physical examinations, clinical 
laboratory tests and vital signs.
Statistical Methods:
Efficacy:
Primary efficacy endpoint is the effect of response to treatment (assessed by SVR12) on clinical 
outcomes, based on subjects in this study and companion study TOPAZ II.  The endpoint will be assessed 
by comparing the incidence of the following events between subjects who achieve SVR12 and those who 
do not using the Cox regression model:
!
All-cause death
!
Liver-related death
!
Liver decompensation
!
Liver transplantation
!
Hepatocellular carcinoma
!
Composite of any of the above outcomes
Secondary endpoint analyses:
!
The long-term change from baseline in liver stiffness (as assessed by transient elastography 
[Fibroscan®]), when available, will be assessed by baseline fibrosis stage and sustained virologic 
response. 
!
The percentage of subjects achieving SVR12 and 2-sided 95% confidence interval will be 
presented by baseline fibrosis score (F0-F1, F2, F3 and F4).

Statistical Methods (Continued):
Resistance:
The following resistance information will be provided for a subset of the subjects who experience 
virologic failure:  1) the amino acid variants at signature resistance-associated positions at baseline 
identified by population nucleotide sequencing and comparison to the appropriate prototypic reference 
sequence, 2) the amino acid variants in available post-baseline samples at signature resistance-associated 
positions identified by population nucleotide sequencing and comparison to the baseline sequence, and
3) the amino acid variants in available post-baseline samples at signature resistance-associated positions 
identified by population nucleotide sequencing and comparison to the appropriate prototypic reference 
sequence.  
In addition, the persistence of viral resistance-associated amino acid variants will be evaluated in selected 
samples during the 5-year (through PT Week 260) post-treatment period.
Safety:
The overall number and percentage of subjects reporting treatment-emergent adverse events will be 
tabulated by Medical Dictionary for Regulatory Activities (MedDRA) system organ class and preferred 
term.  Tabulations will also be provided in which the number of subjects reporting an adverse event 
(MedDRA preferred term) is presented by severity (mild, moderate, or severe) and relationship to study 
drugs.
Change from baseline in laboratory tests and vital sign measurements to each time point of collection will 
be summarized.  Laboratory test and vital sign values that are potentially clinically significant, according 
to predefined criteria, will be identified and the number and percentage of subjects with potentially 
clinically significant values will be calculated.

Introduction
Hepatitis C viral (HCV) infection is a global health problem, with 170 million individuals 
chronically infected worldwide and at risk of developing liver cirrhosis, hepatocellular 
carcinoma, or both.1  Cirrhosis develops after prolonged HCV infection.2  Complications 
of cirrhosis include hepatic decompensation (ascites, encephalopathy, variceal 
hemorrhage, hepatorenal 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 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 HCV-infected patients could reduce the risk of cirrhosis, decompensation, 
cancer and liver-related deaths.  Among patients treated with pegylated interferon 
(pegIFN) and ribavirin (RBV) therapy, achieving a sustained virologic response (SVR) 
was associated with significant reduction in all-cause death compared to subjects who did 
not achieve SVR (5-year mortality rate in HCV genotype 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 
HCV-infected patients with advanced fibrosis or cirrhosis who achieved SVR versus 
those without SVR (9.2% versus 28.2%, respectively).10  Patients with SVR following 
treatment with pegIFN with or without RBV 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 SVR 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 pegIFN and RBV was associated 
with marked reduction in death/liver transplantation, and in liver-related morbidity and 
death.17

In patients with HCV infection, liver histology is a key determinant of clinical 
complications such as decompensation and hepatocellular carcinoma as the risk is greatest 
in patients with advanced fibrosis.  Treatment with IFN-based therapy with or without 
RBV has demonstrated a delay in fibrosis progression in patients who relapse and 
regression of fibrosis in patients with SVR.  While liver biopsy remains the reference 
standard, noninvasive tests such as transient elastography (FibroScan) have emerged as 
validated methods to evaluate degree of liver fibrosis and to monitor progression and 
regression of fibrosis.18  Whereas liver stiffness increased or did not change over time in 
untreated patients, patients treated with pegIFN/RBV therapy exhibited decreases in liver 
stiffness during and after treatment with the greatest improvements observed in patients 
with more advanced fibrosis at baseline.19-21
Combinations of direct-acting antiviral agents (DAAs) targeting different steps of viral 
replication have the potential to significantly improve HCV treatment compared to the 
current interferon-containing regimens for HCV genotype 1 infection by increasing SVR 
rates, eliminating IFN as a component of therapy, increasing the safety and tolerability of 
treatment, shortening duration of therapy and simplifying the treatment algorithm.  In 
addition, wider application of DAA therapy and better responses with combination DAA 
regimens could significantly reduce the public health burden of this disease.
AbbVie's IFN-free regimen for the treatment of chronic HCV genotype 1 infection 
includes 3 DAAs targeting different steps in HCV replication.  ABT-450 is a 
nonstructural protein 3/nonstructural protein 4A (NS3/NS4A) protease inhibitor 
co-administered with the pharmacokinetic enhancer, ritonavir (ABT-450/r); ABT-267 
(ombitasvir) is a NS5A inhibitor, and ABT-333 (dasabuvir) is a NS5B non-nucleoside 
polymerase inhibitor.  
The 3-DAA 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 RBV appears to be safe, 
well tolerated and efficacious in treatment-naïve and treatment-experienced HCV

efficacy results (intent-to-treat) from the Phase 3 studies are listed in Table 1.

Phase 3 Placebo-Controlled Studies:  Studies M11-646 and M13-098
Study M11-646 and Study M13-098 are randomized, placebo-controlled studies that 
assessed the safety and efficacy of 12 weeks of therapy with 3 DAA + RBV in HCV 
genotype 1-infected treatment-naïve subjects (Study M11-646) and prior pegIFN/RBV

non-responders (Study M13-098) without cirrhosis.  Subjects received 3-DAA + 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 + RBV for 12 weeks. 
In Study M11-646, a total of 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 + RBV 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 M13-098, a total of 394 subjects were randomized and received at least one dose 
of study drug, of which 58.4% had HCV genotype 1a, 41.4% had HCV genotype 1b, 
49.0% were prior pegIFN/RBV null responders, 21.9/% were prior pegIFN/RBV partial 
responders, and 29.2% were prior pegIFN/RBV relapsers.  The SVR12 rate for 
treatment-experienced subjects receiving 3-DAA + RBV 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. 
Phase 3 Regimen-Controlled Studies:  Studies M13-389, M13-961 and M14-002
Studies M13-389, M13-961, and M14-002 are randomized, regimen-controlled trials that 
assessed the safety and efficacy of 12 weeks of treatment with 3 DAAs with or without 
RBV.  Studies M13-961 and M14-002 are ribavirin placebo-controlled studies, while 
Study M13-389 is an open-label study.  The patient population was different in each of 
the 3 studies.  Study M13-389 enrolled genotype 1b-infected subjects with prior 
non-response to pegIFN/RBV, Study M13-961 enrolled genotype 1b-infected subjects 
who were treatment-naïve, and Study M14-002 enrolled genotype 1a-infected subjects 
who were treatment-naïve.  All three studies excluded subjects with cirrhosis.
In Study M13-389, a total of 186 subjects were randomized and received at least one dose 
of study drug, of which 34.9% were prior pegIFN/RBV null responders, 28.5% were prior 
pegIFN/RBV partial responders, and 36.6% were prior pegIFN/RBV relapsers.  The

SVR12 rates were 96.6% in the 3-DAA + RBV arm and 100% in the 3-DAA without RBV 
arm.  The difference in SVR12 rates between the 2 regimens met the protocol-specified 
criteria for noninferiority; hence, the 3-DAA regimen without RBV demonstrated 
noninferiority compared to 3-DAA + RBV.  No subject in either arm experienced on-
treatment virologic failure or post-treatment relapse. 
In Study M13-961, a total of 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 DAAs with or without RBV for 12 weeks were 99.5% and 
99.0%, respectively.  The difference in SVR12 rates between the 2 regimens in this study 
also met the protocol-specified criteria for noninferiority.  One of the 419 treated subjects 
(3-DAA + RBV 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 either 3 DAAs with or without RBV for 12 weeks in Study M14-002 were 97.0% 
and 90.2%, respectively.  The SVR12 rate in the 3-DAA arm did not achieve noninferiority 
to the 3-DAA + RBV arm.  Virologic failure was noted in 2/100 (2.0%) subjects (on 
treatment virologic failure:  n = 1; relapse:  n = 1) in the RBV-containing regimen and 
16/205 (7.8%) subjects (on treatment virologic failure:  n = 6; relapse:  n = 10) in the 
RBV-free regimen.  The difference between arms demonstrates that RBV contributes to 
the efficacy in genotype 1a-infected patients and suggests that 3-DAA + RBV is the 
optimal regimen for these patients.
Phase 3 Study in Cirrhotics:  Study M13-099
Study M13-099 is a randomized, multicenter, open-label trial in treatment-naïve subjects 
or subjects previously treated with pegIFN/RBV with chronic HCV genotype 1infection 
with compensated (Child-Pugh A, score ≤ 6) cirrhosis. The 3 DAAs + RBV were 
administered for either 12 or 24 weeks of treatment.

ABT-450/r/ABT-267, ABT-333

A total of 380 subjects were randomized and received at least one dose of study drug, of 
which 68.7% had HCV genotype 1a, 31.3% had HCV genotype 1b, 42.1% were 
treatment-naïve, 36.1% were prior 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 3-DAA + RBV 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 SVR12 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.  Thus, a 12-week treatment regimen is recommended for all patients 
with cirrhosis with the exception of genotype 1a prior null responders, for whom 
24 weeks of treatment provides a higher SVR.
Integrated Safety Results
A summary of treatment-emergent adverse events from the pooled 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.

The most common adverse events regardless of causality are listed in Table 3.  Adverse 
events that occurred at a ≥ 5% incidence in the 3-DAA + RBV regimen versus the placebo 
were considered to be adverse drug reactions related to the study treatment.  These include 
fatigue, nausea, pruritus, insomnia, asthenia, and anemia.  The frequency of these events 
was generally lower in the arm treated without RBV.  In general, rates of adverse events 
were similar in patients with cirrhosis versus patients without cirrhosis.

Transient elevations in total (predominantly indirect) bilirubin may occur due to ABT-450 
inhibition of the bilirubin transporters OATP1B1 and OATP1B3, and RBV-induced 
hemolysis.  The elevations generally peaked by Weeks 1 – 2, declined through the end of

treatment and returned to within the normal range by 4 weeks post-treatment.  Rates of 
hyperbilirubinemia were lower in subjects treated with 3-DAA without RBV compared to 
3-DAA with RBV.  The rates and degree of hyperbilirubinemia were higher in patients 
with cirrhosis, but the temporal pattern of elevation 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 + RBV regimen for 
12 weeks, and 7% and 11% among subjects with cirrhosis who received the 3-DAA + 
RBV regimen for 12 and 24 weeks, respectively.  Grade 3 hemoglobin values were rare.  
The decline in hemoglobin was largely managed with RBV 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 administered with 
RBV.
Transient asymptomatic postbaseline serum ALT elevations of > 5× ULN occurred at a 
frequency of 1% across active treatment arms and were evaluated by an external hepatic 
panel.  The ALT elevations were asymptomatic, usually occurred within the first 4 weeks 
of treatment and typically declined with ongoing treatment.  A disproportionate number of 
the cases were in women on concurrent systemic ethinyl estradiol-containing therapy 
(i.e., combination contraceptives) and discontinuation of the hormonal therapy with 
continuation or brief interruption of the DAA regimen led to resolution in serum ALT 
elevation.  Concomitant use of systemic ethinyl estadiol-containing medications is a risk 
factor for these postbaseline elevations in serum ALT.  There was no increase in the risk 
of ALT elevations greater than 5 × ULN in subjects on estrogens other than ethinyl 
estradiol (i.e., estradiol, conjugated estrogens) or in subjects on only progestins. Among 
the cases of serum ALT elevation thought to be related to the DAA 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.
In summary, the 3-DAA regimen, with or without RBV, 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 RBV.

Transient, asymptomatic serum ALT elevations were observed at a low rate, were not 
associated with hepatic dysfunction and generally resolved with ongoing treatment.

The current study is intended to evaluate the long-term outcomes with ABT-450/r/ 
ABT-267 and ABT-333 with or without RBV for treatment-naïve and IFN/RBV 
treatment-experienced adults with chronic HCV GT1 infection, with or without 
compensated cirrhosis.
3.1
Differences Statement
The 3-DAA regimen with or without RBV was explored in treatment-naïve and 
treatment-experienced HCV GT1-infected subjects with or without compensated cirrhosis, 
in several Phase 3 studies.  These studies were conducted in a randomized, controlled, 
double-blind or open-label fashion.  This study is a Phase 3b, single arm, open-label study 
in approximately 1650 treatment-naïve and IFN-based therapy treatment-experienced 
subjects. 
This is the first study to evaluate long term outcomes with ABT-450/r/ABT-267 and 
ABT-333 with or without RBV for 12 or 24 weeks in subjects with chronic HCV GT1 
infection outside of the US.  The study population comprises HCV GT1 infected subjects 
who are treatment-naïve or treatment-experienced, including subjects with and without 
cirrhosis.  The study will include up to 25% of subjects with compensated cirrhosis which

Benefits and Risks
This Phase 3b study is a single arm study in which eligible HCV genotype 1-infected 
subjects will receive ABT-450/r/ABT-267 and ABT-333 with or without RBV for either 
12 or 24 weeks.  The combination of ABT-450/r/ABT-267 and ABT-333 with or without 
RBV have been evaluated in six Phase 3 studies.  Treatment with ABT-450/r/ABT-267 
and ABT-333 with RBV for 12 weeks resulted in SVR12 in 96.2% of HCV GT1-infected, 
treatment-naïve subjects without cirrhosis in Study M11-646, and in 96.3% of 
HCV GT1-infected, pegIFN/RBV treatment-experienced subjects without cirrhosis in 
Study M13-098.  In Study M13-961, 99.5% and 99.0% of HCV GT1b-infected 
treatment-naïve subjects without cirrhosis achieved SVR12 following treatment with 
ABT-450/r/ABT-267 and ABT-333, with or without RBV for 12 weeks, respectively.  
Similarly, in Study M13-389, 96.6% and 100% of HCV GT1b-infected pegIFN/RBV 
treatment-experienced subjects without cirrhosis achieved SVR12 following treatment 
with ABT-450/r/ABT-267 and ABT-333, with or without RBV for 12 weeks, 
respectively.  ABT-450/r/ABT-267 and ABT-333 with or without RBV was also 
evaluated in Study M14-002.  In Study M14-002, 97.0% and 90.2% of HCV 
GT1a-infected treatment-naïve subjects achieved SVR12 following treatment with and 
without RBV, respectively, suggesting that ABT-450/r/ABT-267 and ABT-333 with RBV 
is the optimal regimen for HCV GT1a-infected subjects.  In this study, HCV 
GT1a-infected subjects will receive 3-DAA with RBV.
The likelihood of successfully curing HCV in compensated cirrhotics following treatment 
with ABT-450/r/ABT-267 and ABT-333 coadministered with RBV was evaluated in 
Study M13-099.  In Study M13-099, 91.8% and 95.9% of HCV GT1-infected 
treatment-naïve and pegIFN/RBV treatment-experienced subjects achieved SVR12
following treatment for 12 and 24 weeks, respectively.  Analysis of subgroups 
demonstrated that the difference in SVR12 rates between treatment arms was due to the 
lower SVR12 rate in GT1a-infected pegIFN/RBV treatment-experienced prior null 
responders treated for 12 weeks.  Among HCV GT1a-infected subjects, partial responders 
and relapsers had higher SVR rates than null responders in the 12-week treatment group, 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14

while similar SVR rates were seen among the null responders, partial responders and 
relapsers treated for 24 weeks, suggesting that the longer duration of 24 weeks is required 
only for HCV GT1a null responders.  SVR rates were high across all subgroups in HCV 
GT1b-infected subjects treated for 12 and 24 weeks.  For this reason, in previous versions 
of this protocol HCV GT1a-infected subjects with compensated cirrhosis and who were 
prior null responders or non-responders to pegIFN/RBV were assigned to receive 3-DAA 
with RBV for 24 weeks, while HCV GT1a-infected subjects with compensated cirrhosis 
who were not prior null responders or non-responders to IFN/RBV were assigned to 
received 3-DAA with RBV for 12 weeks.  In order to align the treatment duration for 
subjects with GT1a infection and compensated cirrhosis with the recommended treatment 
duration that is found in the prescribing information of some approved local labels for the 
AbbVie product containing the regimen included in this study (i.e., ABT-450/r/ABT-267 
and ABT-333), the protocol now specifies that all HCV GT1a-infected subjects with 
compensated cirrhosis will be assigned to receive 3-DAA with RBV for 24 weeks.  
Treatment duration of 12 weeks for HCV GT1a-infected subjects with compensated 
cirrhosis may be selected by the investigator where consistent with the approved local 
label.
HCV GT1a-infected subjects with compensated cirrhosis who were assigned to 12 weeks 
of treatment under a previous version of this protocol will be assigned to 24 weeks of 
treatment unless 1) the investigator determines that a 12-week duration of therapy is 
appropriate based on the approved local label; or 2) the subject has already completed the 
original study drug treatment and additional treatment cannot be initiated within 15 days 
of the date that the original treatment was completed.
ABT-450/r, ABT-267 and ABT-333 with or without RBV have been well tolerated in the 
Phase 3 studies.  Adverse events that are known, and those not previously described, may 
occur with the DAAs or RBV 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/r/ABT-267 and ABT-333 coadministered with or without 
RBV, 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 
HCV GT1-infected subjects, the risk-benefit comparison is favorable.

Study Objectives 
Primary Objective
The primary objective of this study is to evaluate the effect of response to treatment 
(assessed by SVR12 status) on the long-term progression of liver disease in adults with 
chronic HCV GT1 infection who received treatment with ABT-450/r/ABT-267 and 
ABT-333 with or without ribavirin, as measured by all-cause death, liver-related death, 
liver decompensation, liver transplantation, and hepatocellular carcinoma.
Secondary Objectives
●
To evaluate the long-term progression of fibrosis by baseline fibrosis stage and 
sustained virologic response, as measured by change from baseline in liver 
stiffness measured by transient elastography (FibroScan®) when available, in 
adults with genotype 1 (GT1) chronic HCV infection who received treatment 
with ABT-450/r/ABT-267 and ABT-333 with or without ribavirin.
●
To evaluate the percentage of subjects achieving SVR12, with 
ABT-450/r/ABT-267 and ABT-333 with or without RBV in adults with 
GT1chronic HCV infection.

Investigational Plan
5.1
Overall Study Design and Plan:  Description
This is a Phase 3b, open-label, multi-center study designed together with companion study 
TOPAZ-II (M14-222), which shares the primary objective of assessing the effect of 
treatment response on long-term clinical outcomes in adults with GT-1 chronic HCV 
infection with or without compensated cirrhosis, who are either treatment-naïve or 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
31
IFN-based therapy (IFN or pegIFN monotherapy, IFN/RBV or pegIFN/RBV) 
treatment-experienced.  In both studies, subjects will be treated with ABT-450/r/ABT-267 
and ABT-333 with or without RBV.
In the TOPAZ-I and TOPAZ-II studies, the primary objective is to assess the effect of 
treatment response (SVR12) on long-term clinical outcomes, based on the data from both 
studies combined.  The studies differ based on geographic region (this study will be 
conducted outside the US while the TOPAZ-II study will be conducted in the US) and 
based on certain procedures that are not related to the primary outcome.  For example, this 
study will assess the long-term change from baseline in liver elastography, and the 
TOPAZ-II study will utilize a Subject Care Plan Model to facilitate subjects' adherence to 
the study drug.   
The study is designed to enroll 1650 subjects to meet scientific and regulatory objectives 
without enrolling an undue number of subjects in alignment with ethical considerations.  
Therefore, if the target number of subjects has been enrolled, there is a possibility that 
additional subjects in screening will not be enrolled. 
Subjects will be considered treatment-naïve if they have never received any antiviral 
treatment for hepatitis C infection.
Subjects will be considered treatment-experienced if they have received prior IFN-based 
therapy excluding DAAs (including IFN or pegIFN monotherapy, IFN/RBV or 
pegIFN/RBV).  Subjects with documentation required to classify prior response to 
IFN/RBV or pegIFN/RBV treatment will be categorized as one of the following:
●
Prior IFN/RBV or pegIFN/RBV null-responder:  failed to 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 IFN/RBV or pegIFN/RBV 
treatment course;
●
Prior IFN/RBV or pegIFN/RBV partial responder:  achieved at least a 2 log10
IU/mL reduction in HCV RNA by Week 12 during a prior IFN/RBV or 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
32
pegIFN/RBV treatment course but failed to achieve HCV RNA undetectable at 
the end of treatment;
●
Prior IFN/RBV or pegIFN/RBV Relapser:  achieved HCV RNA undetectable 
at end of a prior IFN/RBV or pegIFN/RBV treatment course but HCV RNA 
was detectable following cessation of therapy.
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:
●
Prior IFN/RBV or pegIFN/RBV relapse/breakthrough:  achieved at least one 
documented result of HCV RNA undetectable during a prior IFN/RBV or 
pegIFN/RBV treatment course;
●
Prior IFN/RBV or pegIFN/RBV nonresponder:  did not achieve a documented 
result of HCV RNA undetectable or HCV RNA was detected at the end of 
treatment during a prior IFN/RBV or pegIFN/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/RBV or pegIFN/RBV therapy due to 
IFN intolerability.  
●
Interferon experienced-other:  Includes IFN or pegIFN monotherapy, 
IFN/RBV, or pegIFN/RBV experienced subjects.  Includes subjects who do 
not have adequate documentation of response.
Note:  subjects receiving IFN or pegIFN monotherapy must be categorized as 
'Interferon experienced-other'.
Subjects will be considered to be non-cirrhotic based on a liver biopsy within 24 months 
prior to or during screening demonstrating the absence of cirrhosis (e.g., a METAVIR 
Score of 3 or less, Ishak score of 4 or less) or, if a liver biopsy is unavailable, a screening 
FibroScan result of < 12.5 kPa or a screening FibroTest score of ≤ 0.72 and Aspartate 
Aminotransferase to Platelet Ratio Index (APRI) ≤ 2.

Subjects will be considered to have cirrhosis based on previous histologic diagnosis of 
cirrhosis on a liver biopsy (e.g., Metavir Score of > 3 [including 3 – 4 or 3/4], Ishak score 
of > 4) or, if a liver biopsy is unavailable, a screening FibroScan score ≥ 14.6 kPa or a 
screening FibroTest ≥ 0.73 and APRI > 2. 
In the absence of a qualifying liver biopsy, subjects with a screening FibroScan result that 
is ≥ 12.5 kPa and < 14.6 kPa, a FibroTest result that is ≤ 0.72 and an APRI > 2, or a 
FibroTest result that is ≥ 0.73 and an APRI ≤ 2, should be evaluated based on the 
investigator's clinical judgment to determine the presence or absence of cirrhosis.  The 
investigator will then determine and assign a fibrosis score (either F3 or F4), as shown in 
Table 4, which will be documented in the subject's source and recorded in the IRT system.

F3 or F4).
The number of cirrhotic subjects (an equivalent Metavir score of F4) will be limited to 
less than or approximately equal to 400 subjects; the number of subjects enrolled without 
fibrosis or with portal fibrosis without septa (an equivalent Metavir score of F0 or F1 
respectively) will be limited to 1000 subjects.

Study Design
5.1.1
Screening
At the Screening Visit, subjects who provide written (signed and dated) informed consent 
prior to any study specific procedures, will receive a unique subject number via the 
Interactive Response Technology (IRT) system and will undergo the study procedures
identified in Section 5.3.1 associated with the Screening Visit.  The investigator or 
designee will evaluate whether the subject meets all of the eligibility criteria specified in 
Section 5.2.1 and Section 5.2.2 during the period from the Screening Visit through Study 
Day 1 prior to dosing and record the results of this assessment and the details of the 
informed consent process in the subject's medical records. 
Eligible subjects have up to 42 days following the Screening Visit to enroll into the study.
5.1.1.1
Rescreening
Subjects who meet all eligibility criteria with the exception of up to three exclusionary 
laboratory parameters may rescreen once within the 42-day screening period without prior 
AbbVie approval.  However, subjects with any of the following exclusionary values will 
not be allowed to rescreen:  exclusionary HCV genotype, a positive hepatitis B surface 
antigen, positive human immunodeficiency virus (HIV) antibody, or confirmed 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
35
pregnancy.  Subjects with more than three exclusionary laboratory results will require 
approval from the AbbVie Study Designated Physician prior to rescreening.  Subjects 
being rescreened because of exclusionary laboratory parameter(s) must have the related 
panel(s) repeated (e.g., exclusionary ALT requires a repeat chemistry panel) within the 
same screening period and must meet all eligibility laboratory criteria on any panel that is 
repeated.
For subjects who do not meet the study eligibility criteria, the site personnel must register 
the subject as a screen failure in both IRT and electronic data capture (EDC) systems.
5.1.2
Treatment Period (TP)
Subjects who meet the eligibility criteria will be enrolled to either 12 or 24 weeks of 
combination therapy with or without RBV as described below and Table 5.
HCV GT1-infected subjects who are either treatment-naïve or treatment-experienced will 
receive ABT-450/r/ABT-267 and ABT-333.  Subjects with HCV GT1a infection and all 
GT1-infected subjects with compensated cirrhosis will receive RBV.
The treatment duration will be 12 weeks for all subjects except HCV GT1a-infected 
subjects with compensated cirrhosis who will receive treatment for 24 weeks.  Treatment 
duration of 12 weeks for HCV GT1a-infected subjects with compensated cirrhosis may be 
selected by the investigator where consistent with the approved local label.  Subjects will 
receive study drug regimens according to criteria listed in Table 5.

Treatment for 12 weeks may be considered in some patients where consistent with the approved local label.
The site will enter subject's genotype (1b/Non-1b), fibrosis stage and prior IFN-based 
treatment information in the IRT system in order to assign subject's treatment regimen as 
described in Table 5.
ABT-450/r/ABT-267, ABT-333 and RBV (if applicable) will be administered as 
described in Section 5.5.1.  Subjects will receive instructions about the study drugs and 
the dosing schedule at the Day 1 Visit.  The study drugs will be dispensed at the visits 
indicated in Table 7.
All subjects will continue to return to the site on an outpatient basis through Week 12 or 
Week 24 depending on treatment assignment, following the study procedures identified in 
Table 7.  Subjects could also return to the site as an unscheduled study visit for additional 
safety visits if the investigator feels it is necessary.  Sites should ensure that subjects 
adhere to the study visits.  Sites should provide additional study drug for subjects who 
cannot complete their study visit per the visit schedule to ensure they do not run out of 
study drug prior to their next study visit.  Compliance is critical to ensure adequate drug 
exposure.
Some of the Treatment Period study visits and visit activities (including but not limited to 
vital signs, clinical laboratory tests, and concomitant medication assessment) may be 
conducted in the home or non-hospital/clinic environment by qualified individuals at the 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14

request of the Investigator, with approval from the Sponsor, and with the agreement of the 
subject.
Virologic failure criteria will be evaluated and applied by the investigator as detailed in 
Section 5.4.3. 
Subjects who prematurely discontinue from the Treatment Period should return for a 
Treatment Discontinuation Visit and undergo the study procedures as listed in Table 7 and 
as described in Section 5.4.1. Ideally, this should occur on the day of study drug 
discontinuation, but is recommended to be no later than 2 days after their final dose of 
study drugs and prior to the initiation of any other anti-HCV therapy.
Following completion or premature discontinuation of study drug treatment, all subjects 
will enter the 260-week Post-Treatment Period.  The Treatment Period will assess safety, 
antiviral response, progression of liver fibrosis, patient reported outcomes and clinical 
outcomes, including all-cause death, liver-related death, liver decompensation, occurrence 
of hepatocellular carcinoma, and liver transplantation.
5.1.3
Post-Treatment Period (PT)
All subjects who receive at least one dose of study drugs will be monitored for an 
additional 260 weeks following the last dose of study drugs.  Subjects will return to the 
study site as outlined in Table 7 for Post-Treatment procedures.  The Post-Treatment 
Period will begin the day after the last dose of study drugs.  Subjects could also return to 
the site as an unscheduled study visit for additional safety visits if the investigator feels it 
is necessary.  Subjects who prematurely discontinue the Post-Treatment Period should 
return to the site for a Post-Treatment Discontinuation Visit as outlined in Table 7.
The post-treatment period will assess safety, antiviral response, progression of liver 
fibrosis, patient reported outcomes, and clinical outcomes, including all-cause death, 
liver-related death, hepatocellular carcinoma, liver decompensation and need for liver 
transplantation.

positive ultrasound result will be confirmed with CT scan or MRI.)
11.
HCV genotype performed during screening indicating infection with any genotype 
other than genotype 1.
Rationale for the Exclusion Criteria 
(1)  The impact of AbbVie DAAs on pregnancies is unknown.
(5, 7 – 10)  To ensure safety of the subjects throughout the study.
(3, 4, 6)  To avoid bias for the evaluation of efficacy and safety by concomitant use of 
other medications.
(2, 11)  To exclude subjects with viral infection other than HCV genotype 1.
5.2.3
Prior and Concomitant Therapy
Any medication or vaccine (including over-the-counter or prescription medicines, 
vitamins and/or herbal supplements) that the subject is receiving at the time of enrollment, 
or receives during the study, must be recorded along with the reason for use, date(s) of 
administration including start and end dates, and dosage information including dose, route 
and frequency.
All medications will be recorded until 30 days following the last dose of study drugs.  
Only anti-HCV medications and concomitant medications relevant to SAE of death will 
be collected thereafter.
The AbbVie study-designated physician should be contacted if there are any questions 
regarding concomitant or prior therapies.

5.2.3.1
Prior HCV Therapy
Subjects may be either treatment-naïve or IFN-based therapy (IFN or pegIFN 
monotherapy, IFN/RBV or pegIFN/RBV) treatment-experienced.  Prior or current use of 
any investigational or commercially available anti-HCV agents other than IFN or RBV, 
including telaprevir, boceprevir, sofosbuvir, simeprevir or an investigational agent, 
excludes a subject from this study.  Subjects who previously participated in trials of 
investigational anti-HCV agents may be enrolled if they can produce documentation that 
they received only placebo.
5.2.3.2
Concomitant Therapy
Subjects must be able to safely discontinue any prohibited medications within 2 weeks or 
10 half-lives of the medication whichever is longer, prior to initial study drug 
administration.  Subjects must be consented prior to discontinuing any prohibited 
medications for the purpose of meeting study inclusion criteria.
The investigator or a qualified designee should confirm that concomitant medication can 
be safely administered with DAAs (including ritonavir) and RBV.  Some medications 
may require dose adjustments due to potential for drug-drug interactions.  The investigator 
or qualified designee should review the locally approved labels for concomitant 
medication(s), ribavirin and ritonavir and, where available, ABT-450, ABT-267, and 
ABT-333 and utilize the drug-drug interactions (DDI) tool that will be provided by the 
sponsor to screen concomitant medications at each visit for potential DDIs with study 
drugs.  The investigator or qualified designee should document their DDI review in the 
subject's source or print report and place in subject's source documents.
Management of hematologic growth factor therapy is the responsibility of the 
investigator; growth factors will not be provided by AbbVie, and AbbVie will not 
reimburse for the expense of growth factors or their use.
Investigators should refer to the package inserts for erythropoiesis stimulating agents for 
additional information regarding their use.

Prior to enrollment, subjects should agree to practice two effective methods of birth 
control while receiving study drugs starting with Study Day 1 for 30 days after stopping 
study drug or for 7 months after stopping study drug if receiving RBV.  Subjects using 
ethinyl estradiol-containing medications (including combination oral contraceptives) have 
a higher risk for elevated ALT levels.  Subjects using these medications must discontinue 
them at least 2 weeks prior to study drug administration or 10 half-lives (if known), 
whichever is longer.  Subjects may replace the ethinyl estradiol-containing contraceptive 
with a progestin-only hormonal contraceptive method.
During the Post-Treatment Period, investigators should reassess concomitant medications.  
Subjects may resume revert to pre-study doses, at a minimum of 2 weeks following 
discontinuation of study drugs.
5.2.3.3
Prohibited Therapy
In addition to the medications listed above in Table 6, use of known moderate or strong 
inducers of CYP3A or strong inhibitors or inducers of CYP2C8 is prohibited within 
2 weeks or 10 half-lives of the medication, whichever is longer, prior to the initial dose of 
study drugs and through the first 2 weeks after the subject has completed study drugs in 
the Treatment Period.
The investigator or qualified designee should refer to the RBV labeling and DDI tool for a 
list of prohibited medications.  The investigator or qualified designee should document 
their DDI review in the subject's source or print report and place in subject's source 
documents.  Anti-HCV medications other than those specified in the protocol will not be 
allowed during the Treatment Period of the study.  Some medications may require dose 
adjustments due to potential for drug-drug interactions.
During the Post-Treatment Period, investigators should reassess concomitant medications.  
Subjects may resume revert to pre-study doses, at a minimum of 2 weeks following 
discontinuation of study drugs, if applicable.

5.3.1.1
Study Procedures
The study procedures outlined in Table 7 are discussed in detail in this section with the 
exception of the assessment of concomitant medications (Section 5.2.3), and the 
collection of adverse event information (Section 6.4).  All study data will be recorded in 
the subject's source documentation and then on the appropriate eCRFs, with the exception 
of laboratory data which will be provided to the Sponsor electronically from the 
individual laboratory(ies).
Informed Consent and RBV Information
Signed study-specific informed consent will be obtained from the subject before any study 
procedures are performed.  All subjects will be given the RBV Medication Guide (where 
applicable/locally available).  Details about how informed consent will be obtained and 
documented are provided in Section 9.3.
Medical History
A complete medical history, including history of tobacco and alcohol use, will be taken at 
Screening.  The subject's medical history will be updated at the Study Day 1 Visit.  This 
updated medical history will serve as the baseline for clinical assessment.
Physical Examination
A complete physical examination will be performed at the Screening Visit and at Study 
Day 1.  A symptom-directed physical examination may be performed at any other visit, 
when necessary.
The physical examination performed at the Study Day 1 Visit will serve as the baseline 
physical examination for clinical assessment. Any significant physical examination 
findings after the first dose will be recorded as adverse events.

Vital Signs, Weight and Height
Body temperature, blood pressure, pulse and body weight will be measured at each study 
visit as specified in Table 7 or upon subject discontinuation.  Blood pressure and pulse 
rate will be measured after the subject has been sitting for at least 3 minutes.  The vital 
signs performed on Study Day 1 will serve as the baseline for clinical assessment.  The 
subject will wear lightweight clothing and no shoes during weighing.
Height will be measured only at Screening; the subject will not wear shoes.
12-lead Electrocardiogram
A 12-lead resting ECG will be obtained at the Screening Visit and when clinically needed.
The ECG should be obtained prior to the blood collection.
The ECG will be evaluated by an appropriately trained physician at the site ("local 
reader").  The local reader from the site will interpret, sign, and date ECG tracings and 
will provide his/her global interpretation as a written comment on the tracing using the 
following categories:
●
Normal ECG
●
Abnormal ECG – not clinically significant
●
Abnormal ECG – clinically significant
Only the local reader's assessment of the ECG tracing will be collected on case report 
forms, entered into the database and summarized.  The automatic machine reading 
(i.e., machine-generated measurements and interpretation that are automatically printed on 
the ECG tracing) will not be collected.  
Pregnancy Test
Pregnancy tests are not required for female subjects with documented prior bilateral tubal 
ligation, bilateral oophorectomy or hysterectomy or for subjects who are confirmed to be 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2

postmenopausal.  Confirmation of postmenopausal status measured by FSH will be 
obtained at the Screening Visit only for all female subjects.
For females of childbearing potential:
●
A serum pregnancy test will be performed at the Screening Visit only and sent 
to the central laboratory for analysis.
●
Pregnancy testing will be performed as specified in Table 7 regardless of 
treatment regimen.
●
Females of childbearing potential that were treated with DAAs only in the 
Treatment Period should have urine pregnancy testing done through 
Post-Treatment Week 4.
●
Subjects that receive a RBV containing regimen will have pregnancy tests 
performed monthly throughout the Treatment Period and for a minimum of 
7 months after the discontinuation of RBV, or according to the local RBV 
label and/or local treatment guidelines for RBV. 
●
Urine pregnancy testing will be performed on-site during the study visit if 
there is a scheduled visit.  If there is not a scheduled study visit, subjects may 
either have pregnancy testing performed at the site as an unscheduled study 
visit using an unscheduled test kit or a urine pregnancy test may be conducted 
by the subject at home with a pregnancy test kit provided by the site.  If a urine 
pregnancy test is performed at home, site personnel should contact these 
female study subjects to capture the results of any study-related pregnancy 
tests in the source records only.
●
If a urine pregnancy result is positive a confirmatory hCG serum test should be 
collected and sent to the central lab.
Hepatitis and HIV Screen
HBsAg (hepatitis B surface antigen), anti-HCVAb and anti-HIV Ab will be performed at 
Screening.  A positive anti-HIV Ab test must be confirmed.  The investigator must discuss 
any local reporting requirements to local health agencies with the subject.  The site will 
report these results per local regulations, if necessary.

Clinical Laboratory Samples
Clinical Laboratory Samples will be obtained at a minimum for the clinical laboratory 
tests outlined in Table 8 at the visits specified in Table 7.  Blood samples for serum 
chemistry tests should be collected following a minimum 8-hour at fast on the following 
visits:  Day 1, End of Treatment Visit, and PT Week 52, 104, 156, 208, and 260.  The 
remaining visits may be non-fasting.  Subjects whose visits occur prior to the morning 
dose of study drug should be instructed to fast after midnight.  Subjects whose visits occur 
following the morning dose of study drug should be instructed to fast after breakfast until 
the study visit occurs.
A certified central laboratory will be utilized to process and provide results for the clinical 
laboratory tests.
Instructions regarding the collection, processing, and shipping of these samples will be

study, discontinued from study drug or requires a subject to receive treatment 
will be recorded as an adverse event.
The management of laboratory abnormalities that may occur during the study is described 
in Section 6.7.
Liver Biopsy, FibroScan or FibroTest
At screening, subjects who have not had a liver biopsy within 24 months prior to 
screening, but who otherwise meet all of the inclusion criteria and none of the exclusion 
criteria will undergo either a liver biopsy or non-invasive test (FibroScan or 
FibroTest/APRI prior to enrollment) to determine presence or absence of cirrhosis.  APRI 
should be calculated from samples drawn on the same day.  Selection of liver biopsy or 
non-invasive testing should be based on local standard practice.
FibroScan (if available) and FibroTest will be performed as indicated in Table 7.
Child-Pugh Score and Category
The Child-Pugh score will be calculated prior to the Day 1 Visit and documented on the 
Screening Visit eCRFs for cirrhotic subjects only.  Subjects who were considered to be 
non-cirrhotic at the Screening Visit but identified as cirrhotic (according to definitions 
listed in Section 5.1) during the screening period will return to the site prior to the Study 
Day 1 Visit for Child-Pugh assessment.
The Child-Pugh score uses five clinical measures of liver disease (3 laboratory parameters 
and 2 clinical assessments) and is applicable only to subjects with cirrhosis.  Child-Pugh 
score will be determined at the Screening Visit as indicated in Table 7.  The Child-Pugh 
score will be automatically calculated prior to Day 1 by EDC RAVE once the investigator 
or designated site personnel enters the subject's parameters (as listed in Table 9).  A total

Liver Ultrasound 
In order to monitor for the presence of hepatocellular carcinoma (HCC) an ultrasound of 
the liver will be performed as indicated in Table 7.
For subjects with compensated cirrhosis: 
●
Subjects receiving 12 weeks of treatment will have a liver ultrasound 
performed at the Screening Visit and all post-treatment visits except PT 
Week 4
●
Subjects receiving 24 weeks of treatment will have a liver ultrasound 
performed at the screening visit, Week 24 visit, and all post-treatment visits 
except the PT Week 4 and PT Week 12.
For subjects without cirrhosis:  Liver ultrasound will be performed at the screening visit, 
PT Week 52, PT Week 156 and PT Week 260.
Subjects with a historical negative liver ultrasound, CT or MRI (within 3 months prior to 
screening) are not required to undergo a screening ultrasound.
A positive ultrasound result suspicious for HCC at screening will be confirmed with CT 
scan or MRI during the screening period.  Suspicious ultrasound lesions confirmed by CT 
or MRI are exclusionary.
A positive Ultrasound result suspicious for HCC during the treatment or post-treatment 
period will be confirmed with CT scan or MRI. 
Assessment of Clinical Outcomes
The following clinical outcomes will be assessed during the study:
●
All-cause death:  death due to any cause
●
Liver-related death:  death as the result of a liver-related cause
●
Liver decompensation:  development of any of the following conditions:  
ascites, hepatic encephalopathy or variceal bleeding

●
Liver transplantation:  any subject who had a liver transplantation
●
Hepatocellular carcinoma (HCC):  development of HCC in any subject at any 
time during the study.  HCC is defined by histologic confirmation or a > 1 cm 
mass lesion on cross-sectional imaging that meets the diagnostic criteria for 
HCC according to EASL guidelines.
●
Composite of any of the above outcomes
Clinical Outcome events that occur during the Treatment Period through Post-Treatment 
Week 4 are to be recorded and documented in the eCRF as an AE/SAE (Section 6.0) in 
addition to being captured in the Clinical Outcome eCRF(s).  Clinical Outcome events 
that occur after Post-Treatment Week 4 are considered a progression of the subject's 
existing liver disease and are to be recorded in the Clinical Outcome eCRFs only, except 
when the clinical outcome is death, in which case the AE/SAE eCRF would also need to 
be completed.  This information may be collected over the telephone in the event the 
subject is unable to return to the investigative site.
An independent outcome committee will review and adjudicate the validity of each 
clinical outcome.
Concomitant Medication Assessment
Use of medications (prescription or over-the-counter, including vitamins and herbal 
supplements) from the time of signing the consent through 30 days after last dose of study 
drug will be recorded in the eCRF at each study visit indicated in Table 7.  The 
investigator or qualified designee should review the locally approved labels for 
concomitant medication(s), ribavirin and ritonavir and, where applicable, ABT-450, 
ABT-267, and ABT-333 and should also utilize the DDI tool that will be provided by the 
sponsor for potential drug interactions.  The investigator or qualified designee should 
document their DDI review in the subject's source or print report and place in subject's 
source documents.

During the Post-Treatment Period, all medications will be collected until 30 days 
following the last dose of study drugs.  Only anti-HCV medications and concomitant 
medications relevant to SAE of death will be collected thereafter.
Patient Reported Outcomes (PRO) Instruments (Questionnaires)
Subjects will complete the self-administered PRO instruments (where allowed per local 
regulatory guidelines) on the study days specified in Table 7.  Subjects will be instructed 
to follow the instructions provided with each instrument and to provide the best possible 
response to each item.  Site personnel shall not provide interpretation or assistance to 
subjects other than encouragement to complete the tasks.  Subjects who are functionally 
unable to read or understand any of the instruments may have site personnel read the 
questionnaires to them.  Site personnel will encourage completion of each instrument at 
all applicable visits and will ensure that a response is entered for all items.
PRO instruments will be consistently presented so that subjects will complete the 
Short-Form 36 Version 2 health survey (SF-36v2) instrument first and the FACIT–F 
instrument second.  PRO instruments should be completed as of the first study procedure 
at each visit and prior to any discussion of adverse events or any review of laboratory 
findings, including HCV RNA levels.
Short Form 36 – Version 2 Health Survey (SF-36v2)
The SF-36v2 is a non-disease specific Health Related Quality of Life (HRQoL) 
instrument with extensive use in multiple disease states.  The SF-36v2 instrument 
comprises 36 total items (questions) targeting a subject's functional health and well-being 
in 8 domains (physical functioning, role physical, bodily pain, general health, vitality, 
social functioning, role emotional and mental health) with a recall period of 4 weeks.  
Domain scores are aggregated into a Physical Component Summary score and a Mental 
Component Summary score.  Higher SF-36v2 scores indicate a better state of health.  
Completion of the SF-36v2 should require approximately 10 minutes.

The Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT–F)
The FACIT–F is a symptom specific instrument with a focus on measuring fatigue in a 
variety of chronic diseases or health conditions.  It was originally developed from 
interviews with oncology patients and clinical experts to assess anemia-associated fatigue.  
Its 13-item version assesses peripheral, central, or mixed fatigue with a recall period of 
7 days and yields a summed total score ranging between 0 and 52.  Higher FACIT–F 
scores indicate a lesser degree of fatigue.  Completion of the FACIT–F (version 4) should 
require approximately 5 – 10 minutes.
Assignment of Subject Numbers 
A subject number is assigned at screening via IRT.  Subjects enrolled in the study will 
continue with the same subject number assigned at screening.  Subject numbers will be 
unique 5-digit numbers and will begin with 10001. 
Study Drug Dispensation:
Study drugs will be dispensed at the visits as indicated in Table 7.
Study Drug Returned for IRT Reconciliation
At each visit noted in Table 7, study drug compliance per the number of tablets of 
ABT-450/r/ABT-267, ABT-333, and RBV (if applicable) remaining in each kit (blister 
card for DAAs or bottle for RBV) will be recorded in the IRT system.  Additional 
information regarding treatment compliance can be found in Section 5.5.7.
HCV Genotype and Subtype
Plasma samples for HCV genotype and subtype will be collected at Screening.  Genotype 
and subtype will be assessed using the Versant® HCV genotype Inno-LiPA Assay, 
version 2.0 or higher (LiPA; Siemens Healthcare Diagnostics, Tarrytown, NY).  Only 
subjects with HCV genotype 1 infection will be allowed to enroll.

HCV RNA Levels
Plasma samples for HCV RNA levels will be collected as indicated in Table 7.  Plasma 
HCV RNA levels will be determined for each sample collected by the central laboratory 
using the COBAS® AmpliPrep/COBAS® TaqMan® HCV Test, v2.0.  For this assay the 
lower limit of quantification (LLOQ) is 15 IU/mL.
HCV Resistance Testing Sample 
A plasma sample for HCV resistance testing will be collected at the study visits as 
indicated in Table 7.  Specific instructions for preparation and storage of HCV RNA and 
HCV resistance samples will be provided by the central laboratory, the Sponsor, or its 
designee.
Archive Samples
Archive plasma and serum samples will be collected at the study visits, indicated in 
Table 7.  Archive samples are being collected for possible additional analyses, including 
but not limited to, study drug or metabolite measurements, viral load, safety/efficacy 
assessments, biomarkers of inflammation, HCV gene sequencing, HCV resistance testing, 
and other possible predictors of response, as determined by the Sponsor.
Specific instructions for preparation and storage of archive samples will be provided by 
the central laboratory, the Sponsor, or its designee.
5.3.1.2
Blood Samples for Pharmacogenetic Analysis
IL28B Sample
One (required) 4mLwhole blood sample for deoxyribonucleic acid (DNA) isolation will 
be collected from each subject at screening for Interleukin 28B (IL28B) pharmacogenetic 
analysis and related markers.  If the sample is not collected at this visit, it may be 
collected at any time throughout the study.  This sample will not be used for any testing 
other than IL28B genotypes. 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
63
Specific instructions for sample collection, preparation and storage will be provided by 
the central laboratory, the Sponsor, or its designee.  Samples will be used only for IL28B 
testing and then destroyed.
Optional Pharmacogenetic Sample
One 4 mL whole blood sample for DNA isolation will be collected on Day 1 from each 
subject who consents to provide a sample for pharmacogenetic analysis.  The procedure 
for obtaining and documenting informed consent is discussed in Section 9.3.  If the 
sample is not collected on Day 1, it may be collected at any time throughout the study.
The sample collection tubes will minimally be labeled with "PG-DNA," protocol number, 
and subject number.  Samples will be shipped frozen to AbbVie or a designated laboratory 
for DNA extraction and long-term storage.  Instructions for the preparation and shipment 
of pharmacogenetic samples will be provided in the lab manual.
AbbVie will store the DNA samples in a secure storage space with adequate measures to 
protect confidentiality.  The samples will be retained while research on ABT-450/r/ 
ABT-267, ABT-333 (or drugs of this class) continues but no longer than 20 years.
5.3.1.3
Meals and Dietary Requirements
All study drugs should be dosed together and administered with food, i.e., the AM dose of 
ABT-450/r/ABT-267, ABT-333 and RBV (if applicable) should be taken together with 
food and the PM dose of ABT-333 and RBV (if applicable) should be taken with food.
5.3.2
Efficacy Variables
5.3.2.1
Primary Variable
The primary endpoint is the incidence of all-cause death, liver-related death, liver 
decompensation, liver transplantation, hepatocellular carcinoma, and the composite of any 
of the above outcomes observed during the post-treatment period.

M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
64
5.3.2.2
Secondary Variables
The secondary endpoints are:
●
The mean change from baseline in FibroScan score, when available, during 
treatment period and post-treatment period. 
●
The percentage of subjects achieving SVR12 and corresponding 2-sided
95% confidence interval.
5.3.3
Safety Variables
The following safety evaluations will be analyzed during the study: adverse event 
monitoring and vital signs, physical examination, and laboratory tests assessments.
5.3.4
Pharmacogenetic Variable
IL28B status will be determined for each subject and analyzed as a factor contributing to 
the subject's response to study treatment.  These IL28B genotype results may be analyzed 
as part of a multi-study assessment of IL28B and response to ABT-450, ABT-267, 
ABT-333, or drugs of these classes.  The results may also be used for the development of 
diagnostic tests related to IL28B and study treatment, or drugs of these classes.
The optional DNA samples may be sequenced and data analyzed for genetic factors 
contributing to the disease or to the subject's response to ABT-450, ABT-267, ABT-333, 
or other study treatment, in terms of pharmacokinetics, efficacy, tolerability, and safety.  
Such genetic factors may include genes for drug metabolizing enzymes, drug transport 
proteins, genes within the target pathway, other genes believed to be related to the disease 
or to drug response (including IL28B).  Some genes currently insufficiently characterized 
or unknown may be understood to be important at the time of analysis.  The samples may 
be analyzed as part of a multi-study assessment of genetic factors involved in the response 
to ABT-450, ABT-267, ABT-333, or to drugs of these classes, or the disease state.  The 
samples may also be used for the development of diagnostic tests related to ABT-450, 

ABT-450/r/ABT-267, ABT-333

ABT-267, ABT-333, drugs of these classes, or the disease state.  The results of 
pharmacogenetic analyses may not be reported with the study summary.
5.4
Removal of Subjects from Therapy or Assessment
5.4.1
Discontinuation of Individual Subjects
Each subject has the right to withdraw from the study at any time.  In addition, the 
investigator may discontinue a subject from the study at any time if the investigator 
considers it necessary for any reason, including the occurrence of an adverse event or 
noncompliance with the protocol.
Subjects that discontinue study regardless of cause should be contacted (minimally as a 
telephone assessment) at each yearly scheduled visit to collect the survival status only if 
they provide consent.
If the subject prematurely discontinues during the Treatment Period or the Post-Treatment 
Period, the procedures outlined for the applicable Premature D/C Visit should be 
completed as defined in Table 7.  Ideally for study drug discontinuation, this should occur 
on the day of study drug discontinuation, but no later than 2 days after their final dose of 
study drug and prior to the initiation of any other anti-HCV 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.  
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 EDC.  
If a subject has an ongoing adverse event 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 adverse event is achieved.

66
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 RBV (if 
applicable) to that subject must be discontinued immediately and DAAs may be continued 
at the principal investigator's discretion after discussion with the subject, if the benefit of 
continuing DAAs is felt to outweigh the potential risk.  Specific instructions regarding 
subject pregnancy can be found in Section 6.6.  Subjects will be monitored for SVR in the 
Post-Treatment Period as described in Section 5.1.2.  The investigator is also encouraged 
to report the pregnancy information to the voluntary RBV Pregnancy Registry, if 
applicable.
5.4.2
Discontinuation of Entire Study
AbbVie may terminate this study prematurely, either in its entirety or at any study site, for 
reasonable cause provided that written notice is submitted in advance of the intended 
termination.  The investigator may also terminate the study at his/her site for reasonable 
cause, after providing written notice to AbbVie in advance of the intended termination.  
Advance notice is not required by either party if the study is stopped due to safety 
concerns.  If AbbVie terminates the study for safety reasons, AbbVie will immediately 
notify the investigator by telephone and subsequently provide written instructions for 
study termination.
5.4.3
Discontinuation of Subjects that Meet Virologic Failure 
Criteria
The following criteria will be considered evidence of virologic failure:  
●
Confirmed increase from nadir in HCV RNA (defined as 2 consecutive HCV 
RNA measurements of > 1 log10 IU/mL above nadir) at any time point during 
treatment;
●
Confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA 
measurements ≥ LLOQ) at any point after HCV RNA < LLOQ

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
67
Confirmatory testing for the above criteria should be completed as soon as possible.  
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 the investigator believes the virologic failure is due 
to study drug interruption and/or is compliance related, the AbbVie Study Designated 
Physician should be contacted to discuss alternative management.

Treatment Compliance
The investigator or his/her designated and qualified representatives will 
administer/dispense study drug only to subjects enrolled in the study in accordance with 
the protocol.  The study drug must not be used for reasons other than those described in 
the protocol.
All study drugs will be dispensed to subjects by study-site personnel under the direction 
of the investigator.  At the start of the study, each subject should receive counseling 
regarding the importance of dosing adherence with the treatment regimen with regard to 
virologic response and potential development of resistance.  The start and stop dates of all 
study drugs will be recorded in the source documents and eCRFs.
During the Treatment Period, subjects will be instructed to bring all study drug kits (full, 
partial or empty) to the study site at each study visit.  The study site personnel will inspect 
the contents of the bottles and blister cards at study visits defined as Study Drug Returned 
for IRT Reconciliation in Table 7 and record the status of each one as well as the exact 
number of remaining tablets of ABT-450/r/ABT-267 and ABT-333 or tablets of RBV and 
the date of reconciliation in the IRT system.  If poor adherence is noted, the subject 
should be counseled and this should be documented in the subject's source.

5.5.7
Drug Accountability
The Investigator or his/her representative will verify that study drug supplies are received 
intact and in the correct amounts.  This will be documented in the IRT system.  A current 
(running) and accurate inventory of study drug will be kept by the investigator and will 
include lot number, POR number, number of tablets dispensed, subject number, and date 
dispensed for each subject.  
During the study, should an enrolled subject misplace or damage a study drug bottle, the 
IRT system must be contacted and informed of the misplaced or damaged study drug.  If 
the bottle is damaged, the subject will be requested to return the remaining study drug to 
the site.  Replacement study drug may only be dispensed to the subject by contacting the 
IRT system.  Study drug replacement(s) and an explanation of the reason for the 
misplaced or damaged study drug(s) will be documented within the IRT system at study 
visits defined as Study Drug Returned for IRT Reconciliation as specified in Table 7.  
Study drug start dates for each drug and the last dose of the regimen will be documented 
on the appropriate eCRF.  The status of each bottle, number of tablets remaining in each 
one returned, and the date of reconciliation will be documented in the IRT system.
Upon completion of or discontinuation from the Treatment Period, all original study drug 
bottles (containing unused study drugs) will be returned to the Sponsor (or designee) or 
destroyed on site.  All destruction procedures will be according to instructions from the 
Sponsor and according to local regulations following completion of drug accountability 
procedures.  The number of tablets of each type of study drug returned in each bottle will 
be noted in the IRT.  Labels must remain attached to the containers.

Discussion and Justification of Study Design
5.6.1
Discussion of Study Design and Choice of Control Groups
The combination regimen of ABT-450/r/ABT-267 and ABT-333 with or without RBV for 
12 and 24 weeks has been evaluated in treatment-naïve and pegIFN/RBV 
treatment-experienced HCV GT1-infected subjects, with or without compensated 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2

cirrhosis, in the Phase 3 studies.  Based upon the results from Studies M11-646, M13-098, 
M13-961, M13-389, M14-002 and M13-099 (discussed in detail in Section 3.0), AbbVie 
plans to evaluate the same combination regimen used in the Phase 3 studies in a study 
population of treatment-naïve and IFN-based therapy treatment-experienced HCV 
GT1-infected subjects, with or without compensated cirrhosis. 
The intention of this study is to assess the effect of treatment response on long-term 
clinical outcomes and evaluate the SVR12 following treatment with ABT-450/r/ABT-267 
and ABT-333, with or without RBV.  As such, the absence of randomization, blinding or 
control groups is appropriate.  
5.6.2
Appropriateness of Measurements
Standard statistical, clinical, and laboratory procedures will be utilized in this study.  HCV 
RNA assays are standard and validated.  FibroScan® is a validated non-invasive 
diagnostic test to evaluate liver disease.  The SF-36v2 and FACIT–F instruments are 
standard in the literature and thoroughly validated in the general population and in 
subjects who have chronic health conditions.  The SF-36v2 health survey is the standard 
Health-related Quality of Life instrument in hepatitis C subjects worldwide and FACIT–F 
has been used in hepatitis C registration clinical trials as an assessment tool for fatigue.
5.6.3
Suitability of Subject Population
This study plans to enroll both HCV treatment-naïve and IFN-based therapy treatment-
experienced subjects with genotype 1 chronic HCV, with or without compensated 
cirrhosis.  The subject population to be studied is reflective of the current demographics of 
chronic HCV infection.  Moreover, this study population has been evaluated in the 
Phase 3 studies where more than 2,300 subjects received the 3-DAA combination regimen 
that is planned to be administered in this study.  In the Phase 3 studies, treatment with 
ABT-450/r/ABT-267 and ABT-333 with RBV for 12 weeks resulted in SVR12 in 96% to 
99% of HCV GT1-infected, treatment-naïve subjects without cirrhosis, and 96% to 100% 
of HCV GT1-infected, pegIFN/RBV treatment-experienced subjects without cirrhosis.  
Similarly, high SVR12 rates (99-100%) were seen in HCV GT1b-infected treatment-naïve

with ABT-450/r/ABT-267 and ABT-333, without RBV for 12 weeks.  Among subjects 
with compensated cirrhosis, 92% and 96% of HCV GT1-infected treatment-naïve and 
pegIFN/RBV treatment-experienced subjects achieved SVR12 following treatment with 
ABT-450/r/ABT-267 and ABT-333 with RBV for 12 and 24 weeks, respectively.  The 
DAA regimen ABT-450/r, ABT-267 and ABT-333 with or without RBV has been well 
tolerated in the Phase 3 studies, as evidenced by the low rate of treatment discontinuation 
and serious adverse events. 
5.6.4
Selection of Doses in the Study
ABT-450/r/ABT-267 and ABT-333
Doses of the three DAAs to be used in this study have been administered in the Phase 3 
Studies M11-646, M13-098, M13-389, M13-961, M14-002 and M13-099, and have 
shown high SVR12 rates in combination with each other, with or without RBV, with a 
favorable safety profile.  The maximum dose of ABT-450/r/ABT-267 
75 mg/50 mg/12.5 mg tablets will not exceed 150 mg/100 mg/25 mg per day for 
24 weeks.  The maximum dose of ABT-333 250 mg tablets administered in this study will 
not exceed 500 mg per day for 24 weeks.  
RBV (if applicable)
The daily dose of RBV in this study is 1000 or 1200 mg, divided twice daily, and based 
on subject weight.  This dose is approved for treatment of adult patients with chronic 
hepatitis C infection in combination with pegIFN.  The same dose was studied in the 
Phase 3 Studies M11-646, M13-098, M13-389, M13-961, M14-002 and M13-099 and 
was found to be generally safe and well tolerated and resulted in high SVR rates. 
The maximum RBV dose administered in this study will not exceed 1200 mg, divided 
twice daily for 24 weeks.

Adverse Events
The investigator will monitor each subject for clinical and laboratory evidence of adverse 
events on a routine basis throughout the study.  The investigator will assess and record 
any adverse event in detail including the date of onset, event diagnosis (if known) or 
sign/symptom, severity, time course (end date, ongoing, intermittent), relationship of the 
adverse event to study drug, and any action(s) taken.  For serious adverse events 
considered as having "no reasonable possibility" of being related to study drug, the 
investigator will provide an "Other" cause of the event.  For adverse events to be 
considered intermittent, the events must be of similar nature and severity.  Adverse 
events, whether in response to a query, observed by site personnel, or reported 
spontaneously by the subject will be recorded.
All adverse events will be followed to a satisfactory conclusion.
6.1
Definitions
6.1.1
Adverse Event
An adverse event (AE) is defined as any untoward medical occurrence in a patient or 
clinical investigation subject administered a pharmaceutical product and which does not 
necessarily have a causal relationship with this treatment.  An adverse event can therefore 
be any unfavorable and unintended sign (including an abnormal laboratory finding), 
symptom, or disease temporally associated with the use of a medicinal (investigational) 
product, whether or not the event is considered causally related to the use of the product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as 
well as from accidental or intentional overdose, drug abuse, or drug withdrawal.  Any 
worsening of a pre-existing condition or illness is considered an adverse event.  
Worsening in severity of a reported adverse event should be reported as a new adverse 
event. Laboratory abnormalities and changes in vital signs are considered to be adverse 
events only if they result in discontinuation from the study, necessitate therapeutic 
medical intervention, and/or if the investigator considers them to be adverse events.

M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
75
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event if the surgery/procedure is being performed for a pre-existing condition or 
the surgery/procedure has been pre-planned prior to study entry.  However, if the 
pre-existing condition deteriorates unexpectedly during the study (e.g., surgery performed 
earlier than planned), then the deterioration of the condition for which the elective 
surgery/procedure is being done will be considered an adverse event.
Protocol defined clinical outcomes consist of:
●
All-cause death:  death due to any cause.
●
Liver-related death:  death as the result of a liver-related cause.
●
Liver transplantation:  Any subject who had a liver transplantation.
●
Liver decompensation:  development of any of the following conditions:  
ascites, hepatic encephalopathy, or variceal bleeding.
●
Hepatocellular carcinoma (HCC):  development of HCC in any subject at any 
time during the study.  HCC is defined by histologic confirmation or a > 1 cm 
mass lesion on cross-sectional imaging that meets the diagnostic criteria for 
HCC according to EASL guidelines.
Clinical Outcome events that occur during the Treatment Period through Post Treatment 
Week 4 are to be recorded and documented in eCRF as an AE/SAE in addition to being 
captured in the Clinical Outcome eCRF(s).  Clinical Outcome events that occur after 
Post-Treatment Week 4 are considered a progression of the subject's existing liver disease 
and are to be recorded in the Clinical Outcome eCRFs only, except when the clinical 
outcome is death, in which case the AE/SAE eCRFs would also need to be completed.
These outcomes will form part of the study endpoints and will be reported in the clinical 
study report at the end of the study, or earlier as locally required.

6.1.2
Serious Adverse Events
If an adverse event meets any of the following criteria, it is to be reported to AbbVie as a 
serious adverse event (SAE) within 24 hours of the site being made aware of the serious 
adverse event.
Death of Subject
An event that results in the death of a subject.
Life-Threatening
An event that, in the opinion of the investigator, would have 
resulted in immediate fatality if medical intervention had not 
been taken.  This does not include an event that would have 
been fatal if it had occurred in a more severe form.
Hospitalization or 
Prolongation of 
Hospitalization
An event that results in an admission to the hospital for any 
length of time or prolongs the subject's hospital stay.  This 
does not include an emergency room visit or admission to an 
outpatient facility.
Congenital Anomaly
An anomaly detected at or after birth, or any anomaly that 
results in fetal loss.
Persistent or 
Significant 
Disability/Incapacity
An event that results in a condition that substantially 
interferes with the activities of daily living of a study subject.  
Disability is not intended to include experiences of relatively 
minor medical significance such as headache, nausea, 
vomiting, diarrhea, influenza, and accidental trauma 
(e.g., sprained ankle).

Important Medical 
Event Requiring 
Medical or Surgical 
Intervention to 
Prevent Serious 
Outcome
An important medical event that may not be immediately 
life-threatening or result in death or hospitalization, but based 
on medical judgment may jeopardize the subject and may 
require medical or surgical intervention to prevent any of the 
outcomes listed above (i.e., death of subject, life-threatening, 
hospitalization, prolongation of hospitalization, congenital 
anomaly, or persistent or significant disability/incapacity). 
Additionally, any elective or spontaneous abortion or 
stillbirth is considered an important medical event.  Examples 
of such events include allergic bronchospasm requiring 
intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or 
drug abuse.
For serious adverse events with the outcome of death, the date and cause of death will be 
recorded on the appropriate case report form.
6.2
Adverse Event Severity
The investigator will use the following definitions to rate the severity of each adverse 
event:
Mild
The adverse event is transient and easily tolerated by the subject.
Moderate
The adverse event causes the subject discomfort and interrupts 
the subject's usual activities.
Severe
The adverse event causes considerable interference with the 
subject's usual activities and may be incapacitating or 
life-threatening.
6.3
Relationship to Study Drug
The investigator will use the following definitions to assess the relationship of the adverse 
event to the use of study drug:

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
78
Reasonable 
Possibility
An adverse event where there is evidence to suggest a causal 
relationship between the study drug and the adverse event.
No Reasonable 
Possibility
An adverse event where there is no evidence to suggest a causal 
relationship between the study drug and the adverse event.
For causality assessments, events assessed as having a reasonable possibility of being 
related to the study drug will be considered "associated."  Events assessed as having no 
reasonable possibility of being related to study drug will be considered "not associated."  
In addition, when the investigator has not reported a causality or deemed it not assessable, 
AbbVie will consider the event associated.
If an investigator's opinion of no reasonable possibility of being related to study drug is 
given, an Other cause of event must be provided by the investigator for the serious 
adverse event.
6.4
Adverse Event Collection Period
All serious adverse events, as well as protocol related non-serious adverse events will be 
collected from the time the subject signed the study-specific informed consent until study 
drug administration.  From the time of study drug administration until 30 days following 
discontinuation of study drug treatment has elapsed, all adverse events and serious 
adverse events will be collected, whether solicited or spontaneously reported by the 
subject.  After PT Week 4 until the end of the study only SAE of death will be collected.
Adverse event information will be collected as shown in Figure 2.

Adverse Event Reporting
In the event of a SAE, whether associated with study drug or not, the Investigator will 
notify Clinical Pharmacovigilance within 24 hours of the site being made aware of the 
SAE by entering the SAE data into the electronic data capture (EDC) system.  For SAEs 
that occur prior to the site having access to the RAVE® system, or if RAVE is not 
operable, the forms should be faxed to Clinical Pharmacovigilance within 24 hours of the 
site being made aware of the SAE.

Pregnancy in a study subject must be reported to the AbbVie within 1 working day of the 
site becoming aware of the pregnancy.  Subjects who report a positive pregnancy test 
during the Treatment Period must be notified to stop RBV (if applicable) immediately.  
Administration of DAAs may be continued at the investigator's discretion after discussion 
with the subject, if the benefit of continuing therapy is felt to outweigh the risk 
(Section 5.4.1).
Information regarding a pregnancy occurrence in a study subject and the outcome of the 
pregnancy will be collected for pregnancies occurring up to 30 days after the end of 
treatment with DAAs only, or 7 months (or per local RBV label) after the last dose of 
RBV for treatment with DAAs plus RBV.  The investigator is encouraged to report the 
pregnancy information to the voluntary RBV Pregnancy Registry, if RBV is included 
within the regimen.
Subjects who discontinue study medications due to pregnancy will be monitored for SVR 
in the Post-Treatment Period as described in Section 5.1.
Pregnancy in a study subject is not considered an adverse event.  However, the medical 
outcome of an elective or spontaneous abortion, stillbirth or congenital anomaly is 
considered a serious adverse event and must be reported to the Sponsor within 24 hours of 
the site becoming aware of the event.
6.7
Toxicity Management
For the purpose of medical management, all adverse events and laboratory abnormalities 
that occur during the study must be evaluated by the investigator.  A table of Clinical 
Toxicity Grades for evaluating laboratory abnormalities is provided in Appendix C.  This 
table should be used in determination of the appropriate toxicity management as discussed 
in Sections 6.7.1 through 6.7.5.
A drug-related toxicity is an adverse event or laboratory value outside of the reference 
range that is judged by the investigator or the Sponsor as having a "reasonable possibility"
of being related to the study drug (Section 6.3).  A toxicity is deemed "clinically 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
82
significant" based on the medical judgment of the investigator.  Laboratory abnormalities 
will be managed as deemed clinically appropriate by the investigator until resolved.
Investigators should avoid interrupting study drugs for more than 7 consecutive days.  The 
Investigator should ensure that any study drug interruptions or RBV dose modifications 
and associated adverse events are promptly entered into the appropriate eCRFs.
The toxicity management guidelines below should be followed throughout the Treatment 
Period of the study.
6.7.1
Grade 1 or 2 Laboratory Abnormalities and Mild or Moderate 
Adverse Events
Subjects who develop a mild or moderate adverse event or Grade 1 or 2 laboratory 
abnormality, other than those discussed separately in Section 6.7.4 (Management of 
Decreases in Hemoglobin) for subjects receiving RBV, Section 6.7.5 (Management of 
ALT Elevations) and Section 6.7.6 (Creatinine Clearance), may continue study drugs with 
follow-up per study protocol and in accordance with local standard of care.
6.7.2
Grade 3 or 4 Laboratory Abnormalities 
With the exception of grade 3 or higher abnormalities of total bilirubin, uric acid, 
phosphorus, total cholesterol, triglycerides, or glucose (in subjects with a history of 
diabetes), if a subject experiences a grade 3 or greater abnormal laboratory parameter 
during the Treatment Period, the abnormal laboratory test should be repeated.  If the 
grade 3 or greater abnormality is confirmed, the investigator should assess whether the 
abnormality can be managed medically without interruption of study drug, or whether 
study drugs should be interrupted and the laboratory parameter followed until it improves.  
If study drugs are interrupted and restarted and the abnormality recurs, then study drugs 
should be permanently discontinued. 
Decreases in serum hemoglobin or in calculated creatinine clearance for subjects 
receiving RBV or elevations of serum ALT should be managed according to the guidance 
in Section 6.7.4, Section 6.7.5 and Section 6.7.6 below.  Grade 3 or greater abnormalities 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
83
of total bilirubin, uric acid, phosphorus, total cholesterol, triglycerides or glucose (in 
subjects with a history of diabetes) should be managed medically as appropriate and do 
not require confirmation or study drug interruption, unless deemed necessary by the 
investigator.
6.7.3
Severe Adverse Events or Serious Adverse Events
If a subject experiences a severe adverse event or a serious adverse event that the 
investigator considers to have a reasonable possibility of relationship to study drug, the 
investigator should assess whether the adverse event can be managed medically without 
interruption of study drug, or whether study drugs should be interrupted until it improves.  
If study drugs are interrupted and restarted and the adverse event recurs, then study drugs 
should be permanently discontinued. 
If a subject experiences a severe adverse event or serious adverse event that is considered 
unrelated (no reasonable possibility) to the study drugs, it is not necessary to interrupt 
study drugs unless an interruption is required because of the nature of the event 
(e.g., unable to take oral medications).
The investigator should ensure that all serious adverse events are reported to AbbVie 
within 24 hours of awareness.  Serious adverse event follow-up information, including 
associated dose interruptions (or discontinuations), must be reported to AbbVie within 
24 hours of awareness by entering updated SAE information into the appropriate eCRFs.
Severe adverse events and any associated dose interruptions (or discontinuations) should 
be entered into the appropriate eCRFs.
6.7.4
Management of Decreases in Hemoglobin
For subjects not receiving ribavirin:  
Hemoglobin decreases should be managed according to grade based on the guidance in 
Section 6.7.1 – Section 6.7.2 above.

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
84
For subjects receiving ribavirin:  
Reductions in hemoglobin are a well characterized side effect of RBV exposure.  If a 
subject receiving the standard dose of RBV experiences a hemoglobin decrease meeting 
one of the criteria outlined in Table 12, a confirmatory test should be performed.  If the 
hemoglobin decrease is confirmed, the management guidelines in Table 12 should be 
followed.  Management will be different for subjects without a history of known cardiac 
disease and subjects with known cardiac disease.  Subjects experiencing decreases in 
hemoglobin that do not meet the criteria outlined in Table 12 may need hemoglobin 
evaluations at more frequent intervals at the discretion of the investigator.  
The dose of RBV should not be further modified in subjects with creatinine clearance 
< 50 mL/min who are receiving a reduced dose of RBV.  Reductions in hemoglobin in 
these subjects should be managed as medically appropriate and as outlined in Table 12.
Use of hematologic growth factors (such as erythropoietin or filgrastim) or blood 
transfusions are permitted at the discretion of the investigator.  Management of 
hematologic growth factor therapy is the responsibility of the Investigator, and growth 
factors will not be provided by AbbVie.
Alternate management of hemoglobin decreases outside of these criteria is permitted with 
approval of the AbbVie Study Designated Physician.

increases to ≥ 10 g/dL, may increase RBV; with gradual dose increases 
in 200 mg increments towards original dose.
< 8.5 g/dL
Interrupt RBV.  Manage the subject as medically appropriate.
If hemoglobin increases to ≥ 8.5 g/dL, RBV may be restarted.

≥50 mL/min
Hemoglobin decrease of 
≥2 g/dL during any 4-week 
treatment period
Reduce RBV dose.*  If a subsequent hemoglobin result is greater than 
the level that triggered the dose reduction, RBV dose may be increased; 
with gradual dose increases in 200 mg increments.
< 12 g/dL after a 4-week 
RBV dose reduction
Interrupt RBV.  Manage the subject as medically appropriate.
If hemoglobin increases to ≥ 12 g/dL RBV may be restarted.
For subjects with creatinine clearance < 50 mL/min
< 10 g/dL
Interrupt RBV.  Manage the subject as medically appropriate.
If hemoglobin increases to ≥ 10 g/dL, RBV may be restarted. If 
creatinine clearance increases to ≥ 50 mL/min, refer to guidance above.
*
1st dose reduction of RBV is by 200 mg/day or per local label.  If needed, 2nd dose reduction of RBV is by an 
additional 200 mg/day.  Subjects whose dose of RBV is reduced to 600 mg daily receive one 200 mg tablet in the 
morning and two 200 mg tablets in the evening.
6.7.5
Management of ALT Elevations
Transient asymptomatic Grade 3-4 ALT elevations have been observed in approximately 
1% of subjects receiving ABT-450/r-containing regimens.  If a subject experiences a 
post-baseline increase in ALT to > 5 × ULN that is increased from the previous 
measurement, the subject should have a confirmatory ALT measurement performed. 
If the ALT increase is confirmed to be > 5 × ULN and increased from the previous 
measurement, the recommendations below should be followed:

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
86
●
Evaluate for alternative etiology of ALT elevation:  update medical history and 
concomitant medications eCRF (if applicable), and obtain additional testing as 
appropriate.
●
Manage the subject as medically appropriate.
●
Repeat ALT, AST, total and fractionated bilirubin, alkaline phosphatase and 
INR within 1 week.  Repeat liver chemistries as indicated until resolution.
●
Discontinue study drugs if any of the following is observed at any time:
○
ALT level is > 20 × ULN
○
Increasing direct bilirubin, increasing INR, or onset of symptoms/signs of 
hepatitis.
Alternate management of ALT increases is permitted with approval of the AbbVie Study 
Designated Physician.
6.7.6
Creatinine Clearance
If calculated creatinine clearance (by Cockcroft-Gault formula) is confirmed to have 
decreased to < 50 mL/minute (in a subject with a baseline creatinine clearance 
≥50 mL/min), or to below 30 mL/minute (in a subject with a baseline creatinine clearance 
< 50 mL/min), medical evaluation should include a full review of current medications, 
including those taken on an as needed basis, those which are sold over the counter and any 
dietary and herbal supplements, and appropriate dose reduction or discontinuation based
on impaired renal function should be done (if applicable).  RBV dose should be adjusted 
as in Table 13.  Alternative management of RBV dose in the setting of reduced renal 
function will require approval of the AbbVie Study Designated Physician.
The investigator should also consider whether drug-drug interactions with concomitant 
medications may have contributed to the decrease in creatinine clearance, and whether 
discontinuation or substitution of the possible interacting drug might be needed.  For 
example, drug interactions between DAAs and some antihypertensive medications could 
potentially increase exposures of the antihypertensive, which may lead to reduction in 
renal function.  If anti-hypertensive medications are adjusted, vital signs should be 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2

monitored to ensure appropriate blood pressure control.  Refer to Section 5.2.3 for 
additional information regarding drug-drug interactions.

If creatinine clearance improves, the site should perform all necessary readjustment of any 
dose modifications that have been made.  If creatinine clearance improves to above the 
level that triggered the RBV dose reduction, RBV dose may be increased accordingly.
The Investigator should ensure that any concomitant medication changes, RBV dose 
reductions, and study drug discontinuations, as well as consequent related adverse events 
are entered into the appropriate eCRFs.
Clinical Toxicity Table will be appended to protocol in Appendix C.  
7.0
Protocol Deviations
AbbVie does not allow intentional/prospective deviations from the protocol.  The 
principal investigator is responsible for complying with all protocol requirements, and 
applicable global and local laws regarding protocol deviations.  If a protocol deviation 
occurs (or is identified) after a subject has been enrolled, the principal investigator is 
responsible for notifying Independent Ethics Committee (IEC)/Independent Review 
Board (IRB) regulatory authorities (as applicable), and their assigned Monitor or the 
following AbbVie personnel:

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
89
primary efficacy analysis on clinical outcomes will be performed on all subjects in the 
ITT population. 
The ITT-I population will consist of all subjects enrolled in this study only who receive at 
least one dose of study drug.  All other efficacy, safety, and demographic analyses will be 
performed on all subjects in the ITT-I population. 
No data will be imputed for any efficacy or safety analyses except for the PRO 
questionnaires and for analyses of the HCV RNA endpoints.  If a respondent answers at 
least 50% of the items in a multi-item scale of the SF-36v2, the missing items will be 
imputed with the average score of the answered items in the same scale.  In cases where 
the respondent did not answer at least 50% of the items, the score for that domain will be 
considered missing.  Similarly, the missing items of the FACIT-F questionnaire will be 
imputed with the average score of the answered items in the same scale as long as at least 
50% of the items in the scale were answered.  The SF-36v2 Mental and Physical 
Component Summary measures will not be computed if any domain is missing.  
HCV RNA values will be selected for the SVR12 analysis based on the defined visit 
windows.  When there is no HCV RNA value in a visit window based on defined visit 
windows, the closest values before and after the window, regardless of the value chosen 
for the subsequent and preceding window, will be used for the flanking imputation 
described below. 
If a subject has a missing HCV RNA value at a post-Day 1 Visit but with undetectable or 
unquantifiable HCV RNA levels at both the preceding value and succeeding value, the 
HCV RNA level will be considered undetectable or unquantifiable, respectively, at this 
visit for this subject.  In addition, if a subject has an unquantifiable HCV RNA level at the 
preceding value and an undetectable HCV RNA level at the succeeding value, or vice 
versa, the HCV RNA level will be imputed as unquantifiable at this visit for this subject.  
Subsequent to this flanking imputation, if a subject is missing a value for the visit window 
associated with the analysis, the subject will be imputed as a visit failure (i.e., not 
undetectable or unquantifiable).  For SVR12 analysis, if there is no value in the appropriate 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2

window but there is an HCV RNA value after the window, then it will be imputed into the 
SVR12 window.
8.1.1
Demographics
Demographics and baseline characteristics will be summarized for all subjects in the ITT 
population.  Demographics include age, weight, height, and BMI, and the frequency of 
gender, race and ethnicity.  Baseline characteristics will include HCV genotype 1 subtype 
(1a, 1b, other), IL28B genotype ([CC, CT, or TT] and [CC or non-CC]), IFN treatment 
history (treatment-naïve [IFN-eligible, IFN-ineligible] or IFN-based treatment-
experienced [null responder, partial responder, relapse, prior relapse/breakthrough, prior 
nonresponder, interferon intolerant and interferon experienced-other]), baseline HCV 
RNA levels [(continuous) and (≤800,000 IU/mL or > 800,000 IU/mL)], baseline 
HOMA-IR (< 3 mU × mmol/L2 or ≥ 3 mU × mmol/L2), baseline fibrosis stage (F0-1, F2, 
F3, F4), tobacco (user, ex-user, or non-user) and alcohol use (drinker, ex-drinker, or 
non-drinker) status.  Summary statistics (N, mean, median, SD, and range) will be 
generated for continuous variables (e.g., age and BMI).  The number and percentage of 
subjects will be presented for categorical variables (e.g., gender and race).
8.1.2
Efficacy
The primary efficacy analysis on clinical outcomes will be performed on all subjects in 
the ITT population.  All other efficacy analyses will be performed on the ITT-I population
At sites where FibroScan is available, subjects will have FibroScan® performed at 
Screening, End-of-Treatment Visit and throughout the Treatment and Post-Treatment 
Period as indicated in Table 7 for the purpose of assessing changes in liver fibrosis over

Plasma HCV RNA levels will be determined for each sample collected by the central 
laboratory using the COBAS® AmpliPrep/COBAS® TaqMan® HCV Test, v2.0.  For this 
assay, the lower limit of quantification (LLOQ) is 15 IU/mL.  HCV RNA results that are 
detectable but not quantifiable are reported as "HCV RNA is detected, less than 15 IU/mL 
HCV RNA".
8.1.2.1
Primary Efficacy Endpoint
The primary efficacy endpoint is to assess the effect of response to treatment on clinical 
outcomes by comparing the time to incidence of the following events between subjects 
who achieve SVR12 and those who do not using a Cox regression model:
●
All-cause death
●
Liver-related death
●
Liver decompensation
●
Liver transplantation
●
Hepatocellular carcinoma
●
Composite of any of the above outcomes
8.1.2.2
Secondary Efficacy Endpoints
The secondary efficacy endpoints are:
●
The effect of sustained virologic response and baseline fibrosis stage on 
longitudinal change from baseline in Fibroscan score (assessed at the end of 
treatment and/or post-treatment visits) will be evaluated by comparing mean 
change between subjects who achieve SVR12 and those who do not.  Point 
estimates and 95% confidence intervals will be provided.
●
The percentage of subjects achieving SVR12 (HCV RNA < LLOQ 12 weeks after 
the last actual dose of study drug).  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.

Subgroup Analyses
Subgroup efficacy analyses on clinical outcomes, liver stiffness and the percentage of 
subjects achieving SVR12 will be performed as appropriate and useful.
8.1.2.4
Additional Efficacy Endpoints
The following additional efficacy endpoints will be analyzed and summarized:
●
The number and percentage of subjects meeting each and any of the following 
SVR12 non-response categories:
○
On-treatment virologic failure (rebound or fail to suppress)
○
Relapse 
○
Premature study drug discontinuation with no on-treatment virologic 
failure
○
Missing SVR12 data 
○
Other
The following analyses of patient reported outcomes (PROs) will be performed.  For PRO 
analysis, summary statistics (n, mean, SD, minimum and maximum) will be provided at 
Day 1 and each applicable visit.  The mean change from baseline in quality of life and 
fatigueto Post Treatment Week 12 and to Post-Treatment Week 24 (assessed by the 
Short-Form 36 Version 2 health survey (SF-36v2) questionnaires) and (The Functional 
Assessment of Chronic Illness Therapy – Fatigue (FACIT–F) and will be compared by 
appropriate baseline fibrosis stages.  In particular, the comparison of the mean change 
from baseline to Post-Treatment Week 12 and to Post Treatment Week 24 in the SF-36 
V2 Vitality scale, Mental Component Summary score, Physical Component Summary 
score and FACIT–F score, will be performed using ANCOVA analyses with appropriate 
baseline fibrosis stage as factor, and baseline PRO score and SVR12 status as covariates.  
Additional analysis on the PRO data will be performed as useful and appropriate.

8.1.3
Resistance
For subjects who do not achieve or maintain SVR12, and who are included in the analyses 
described below, the sample closest in time after virologic failure with an HCV RNA 
level ≥ 1000 IU/mL will be used if the HCV RNA level at the time of failure is 
< 1000 IU/mL.  The prototypic reference strains with their associated GenBank Accession 
IDs for sequence analyses are genotype 1a-H77 (NC_004102) and 1b-Con1 (AJ238799).
For each DAA target, resistance-associated signature amino acid variants will be 
identified by AbbVie Clinical Virology.  Amino acid positions where resistance-
associated variants have been identified in vitro and/or in vivo are 1) for ABT-450:  36, 
43, 56, 155, 156, and 168 in NS3 for genotype 1a; 56, 155, 156, and 168 in NS3 for 
genotype 1b; 2) for ABT-267:  28, 30, 31, 32, 58, and 93 in NS5A for genotype 1a; 28, 
29, 30, 31, 32, 58, and 93 in NS5A for genotype 1b; and 3) for ABT-333:  316, 414, 446, 
448, 451 553, 554, 555, 556, 558, 559, and 561 in NS5B for genotype 1a; 316, 368, 411, 
414, 445, 448, 553, 556, 558, and 559 in NS5B for genotype 1b.
The following definitions will be used in the resistance analyses:
●
Baseline sample:  sample collected before the first dose of DAA study drug.
●
Baseline variant:  a variant in the baseline sample determined by comparison 
of the amino acid sequence of the baseline sample to the appropriate prototypic 
reference amino acid sequence for a given DAA target (NS3, NS5A, or 
NS5B).
●
Post-baseline variant:  an amino acid variant in a post-baseline time point 
sample that was not detected at baseline.
●
Linked variant by population sequencing:  2 or more signature 
resistance-associated or emerged amino acid variants identified within a target 
by population sequencing, and no mixture of amino acids is detected at any of 
these positions.
For those samples evaluated, a listing by subject of all baseline variants relative to 
prototypic reference sequence at signature resistance-associated amino acid positions will 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
94
be provided for each DAA target (NS3, NS5A, and/or NS5B).  In addition, a summary of 
the number and percentage of subjects with each baseline variant at a signature 
resistance-associated amino acid position within each target by HCV subtype out of the 
total number of baseline samples sequenced will also be provided.
The HCV amino acid sequence at post-baseline time points with an HCV RNA level of 
≥1000 IU/mL that are analyzed will be compared to the baseline and appropriate 
prototypic reference amino acid sequences.  Listings by subject and time point of all 
post-baseline variants at signature resistance-associated amino acid positions relative to 
the baseline and to the appropriate prototypic reference amino acid sequences will be 
provided.  
Linkage between variants at signature resistance-associated amino acid positions by 
population sequencing will also be evaluated.  A listing by subject and time point of the 
linked variants by population sequencing will be provided.  In addition, a summary of the 
number and percentage of subjects with linked variants within each target by HCV 
subtype out of the total number of baseline samples sequenced will be provided.
The persistence of resistance-associated substitutions that emerged for each target (NS3, 
NS5A, and NS5B) will be assessed by population sequencing at selected post-treatment 
time points in a subset of subjects.  Listings by subject and time point of all post-baseline 
variants at signature resistance-associated amino acid positions relative to the baseline 
amino acid sequence will be provided for each DAA target (NS3, NS5A, and NS5B).
8.1.4
Safety
All subjects who receive at least one dose of study drug will be included in the safety 
analyses.
8.1.5
Adverse Events
Adverse events will be coded using the Medical Dictionary for Regulatory Activities 
(MedDRA).  The number and percentage of subject treatment-emergent adverse events 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
95
(i.e., any event that begins or worsens in severity after initiation of study drug through 
30 days post-study drug dosing) will be tabulated by primary MedDRA System Organ 
Class (SOC) and preferred term (PT).  The tabulation of the number of subjects with 
treatment-emergent adverse events by severity rating and relationship to study drug will 
also be provided.  Subjects reporting more than one adverse event for a given MedDRA 
preferred term will be counted only once for that term using the most severe incident for 
the severity rating table and the most related for the relationship to study drug table.  
Subjects reporting more than one type of event within a SOC will be counted only once 
for that SOC.
Additional analyses will be performed if useful and appropriate.
8.1.6
Clinical Laboratory Data
Clinical laboratory tests will be summarized at each visit.  The baseline value will be the 
last measurement prior to the initial dose of study drug.  Mean changes from baseline to 
each Post Baseline Visit will be summarized descriptively.
Laboratory data values collected during the Treatment Period will be categorized as low, 
normal, or high based on reference ranges of the laboratory used in this study.  The 
number and percent of subjects who experience post-baseline shifts during treatment in 
clinical laboratory values from low/normal to high and high/normal to low based on the 
normal range will be summarized.
In addition, the number and percentage of subjects with post-baseline values meeting 
pre-specified criteria for Potentially Clinically Significant laboratory values during 
treatment will be summarized.  Additional analyses will be performed if useful and 
appropriate.
8.1.7
Vital Signs Data
Mean changes in temperature, systolic and diastolic blood pressure, pulse, and weight 
from Day 1 to each Post Baseline Visit will be summarized descriptively.  Number and 

ABT-450/r/ABT-267, ABT-333
M14-423 Protocol Amendment 2
EudraCT 2014-001022-14
96
percentage of subjects with post-baseline values meeting pre-defined criteria for 
Potentially Clinically Significant vital signs values during treatment will be summarized.  
8.2
Determination of Sample Size
Assuming 4% of subjects do not achieve SVR12 and assuming the 5-year event rate of the 
composite clinical outcome is 20% in the non-SVR12 subjects, with a 75% reduction in  
SVR12 subjects (Hazard Ratio of 0.25), then based on two-sample log rank test (using 
EAST 6.0), a sample size of at least 2000subjects enrolled in TOPAZ-I and TOPAZ-II 
provides greater than 80% power to reject the null hypothesis of no difference between 
SVR12 and non-SVR12 subjects in the rate of clinical outcome events.  Power calculations 
were based on a dropout rate of up to 20%.

Fourth paragraph previously read:
Transient asymptomatic postbaseline serum ALT elevations of > 5× ULN occurred at a 
frequency of 1% across active treatment arms and were evaluated by an external hepatic 
panel.  The ALT elevations were asymptomatic, usually occurred within the first 4 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 DAA regimen led to resolution in serum 
ALT elevation.  Concomitant use of systemic estrogen-containing medications is a risk 
factor for these postbaseline elevations in serum ALT.  No ALT elevations greater than 
5 times ULN were observed in subjects receiving progestins only or in subjects receiving 
topical vaginal estrogen preparations.  Among the cases of serum ALT elevation thought 
to be related to the DAA 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.

factor for these postbaseline elevations in serum ALT.  There was no increase in the risk 
of ALT elevations greater than 5 × ULN in subjects on estrogens other than ethinyl 
estradiol (i.e., estradiol, conjugated estrogens) or in subjects on only progestins. Among 
the cases of serum ALT elevation thought to be related to the DAA regimen, none

Second paragraph previously read:
The likelihood of successfully curing HCV in compensated cirrhotics following treatment 
with ABT-450/r/ABT-267 and ABT-333 coadministered with RBV was evaluated in 
Study M13-099.  In Study M13-099, 91.8% and 95.9% of HCV GT1-infected 
treatment-naïve and pegIFN/RBV treatment-experienced subjects achieved SVR12
following treatment for 12 and 24 weeks, respectively.  Analysis of subgroups 
demonstrated that the difference in SVR12 rates between treatment arms was due to the 
lower SVR12 rate in GT1a-infected pegIFN/RBV treatment-experienced prior null 
responders treated for 12 weeks.  Among HCV GT1a-infected subjects, partial responders 
and relapsers had higher SVR rates than null responders in the 12 week treatment group, 
while similar SVR rates were seen among the null responders, partial responders and 
relapsers treated for 24 weeks, suggesting that the longer duration of 24 weeks is required 
only for HCV GT1a null responders.  SVR rates were high across all subgroups in HCV 
GT1b-infected subjects treated for 12 and 24 weeks.  For this reason, HCV GT1a-infected 
subjects with compensated cirrhosis and were prior null responders to pegIFN/RBV will 
receive 3-DAA with RBV for 24 weeks.

only for HCV GT1a null responders.  SVR rates were high across all subgroups in HCV 
GT1b-infected subjects treated for 12 and 24 weeks.  For this reason, in previous versions 
of this protocol HCV GT1a-infected subjects with compensated cirrhosis and who were 
prior null responders or non-responders to pegIFN/RBV were assigned to receive 3-DAA 
with RBV for 24 weeks, while HCV GT1a-infected subjects with compensated cirrhosis 
who were not prior null responders or non-responders to IFN/RBV were assigned to 
received 3-DAA with RBV for 12 weeks.  In order to align the treatment duration for 
subjects with GT1a infection and compensated cirrhosis with the recommended treatment 
duration that is found in the prescribing information of some approved local labels for the 
AbbVie product containing the regimen included in this study (i.e., ABT-450/r/ABT-267 
and ABT-333), the protocol now specifies that all HCV GT1a-infected subjects with 
compensated cirrhosis will be assigned to receive 3-DAA with RBV for 24 weeks.  
Treatment duration of 12 weeks for HCV GT1a-infected subjects with compensated 
cirrhosis may be selected by the investigator where consistent with the approved local 
label.

appropriate based on the approved local label; or 2) the subject has already completed the 
original study drug treatment and additional treatment cannot be initiated within 15 days 
of the date that the original treatment was completed.
