Introduction
OVERVIEW OF HEPATITIS C VIRUS (HCV)
VETERANS ADMINISTRATION PATIENT CARE SERVICES
Introduction to HCV
• Hepatitis C is a viral liver infection and the most
common blood-borne infection in the United States
• The virus lacks a proofreading polymerase – the
resulting mutations allow the virus to evade the
immune system

Viral Transmission
• Primarily through large or repeated percutaneous exposure
to infectious blood
– Injection drug use
– Receipt of blood, blood products, or organs
– Needlestick injuries
– Birth to an HCV-infected mother
• Infrequently through
– Sexual contact
– Sharing personal items (e.g. razors)
– Other invasive healthcare procedures

Burden of Disease
• Chronic HCV carries
significant morbidity and
mortality as the primary
reason for:
– Liver transplant
and the leading cause of:
– End-stage liver disease
– Liver-related death
– Hepatocellular carcinoma
(HCC)

Barriers to Treatment
Less
than
20% of HCV-infected
receive
treatment.
About
50%
of HCV-infected
personspersons
are unaware
they
are infected.
Lack of Appropriate Screening
Patient-related Barriers
•
•
•
•
•
Lack of knowledge of risk factors
Asymptomatic; physical exam and
routine labs not remarkable
VETERANS ADMINISTRATION PATIENT CARE SERVICES
Contraindications to treatment
Lack of acceptance of treatment
Lack of access to treatment
Overcoming Barriers
• Education
− Healthcare providers
− Patients
• A multidisciplinary approach to
care increases the proportion of
patients with psychiatric or
substance abuse comorbidities
who begin treatment. This
approach ensures that the most
appropriate course is chosen.
VETERANS ADMINISTRATION PATIENT CARE SERVICES
Patient-related Barriers to
Treatment Initiation
● Contraindications to treatment
Medical or psychiatric comorbidities
● Lack of acceptance of treatment
Asymptomatic nature of disease
Competing priorities
Perceived low treatment efficacy
Perceived long treatment duration
Adverse effects
● Lack of access to treatment
Cost
Distance to specialist
Overcoming Barriers
• Current pharmacologic therapies
provide better side effect profiles,
shorter durations, and very high cure
rates. These make healthcare
providers more capable than ever of
maximizing the individuals screened,
treated, and cured.
• Telemedicine and knowledge
networks have successfully overcome
geographic barriers to treatment
centers as well as to specialists.

Recommendations for HCV Testing those
with Ongoing Risk Factors
AASLD/IDSA HCV Guidance
• Annual HCV testing is recommended for persons who inject
drugs and for HIV-seropositive men who have unprotected sex
with men.
• Periodic testing should be offered to other persons with ongoing
risk factors for exposure to HCV.
VETERANS ADMINISTRATION PATIENT CARE SERVICES
Construct an individualized management
plan for both treatment-naïve and treatmentexperienced patients with HCV infection.
OBJECTIVE 3
Develop a monitoring and assessment plan
for patients with HCV infection who are
initiated on various pharmacotherapies.
OBJECTIVE 4
VETERANS ADMINISTRATION PATIENT CARE SERVICES
When and in Whom To Initiate Treatment
AASLD/IDSA
All patients with chronic HCV infection should be treated when
(s)he is ready and the necessary resources are available.
Exception: those with short life expectancies that cannot be remediated by treating
HCV, by transplantation, or by other directed therapy.

monotherapy is not effective for the
treatment of chronic hepatitis C virus.
• Weight-based dosing given in two divided
doses daily.
• Ribavirin may cause birth defects and/or
death of the exposed fetus. Use 2 forms of
contraception to avoid pregnancy (in female
patients and female partners of male
patients) during and for 6 months after
therapy.
• This drug can cause hemolytic anemia which
can cause significant fatigue, make heart
disease worse, and lead to heart attacks. Tell
your doctor if you have ever had heart
problems. Do not take this drug if you have
ever had very bad heart disease or heart
problems that are not being treated. Call your
doctor right away if you have chest pain while
taking this drug.
• This drug is typically dosed twice daily.
• Take a missed dose as soon as you think
about it. If it is close to the time for your next
dose, skip the missed dose and resume your
regular dosing schedule. Do not double doses.
Used to treat HCV genotypes

Hemolytic anemia (oral): The primary clinical
toxicity of ribavirin is hemolytic anemia,
which may result in worsening of cardiac
disease and lead to fatal and nonfatal
myocardial infarctions. Anemia usually
occurs within 1 to 2 weeks of therapy
initiation
Pregnancy (oral): Significant teratogenic
and/or embryocidal effects. Ribavirin has a
multiple-dose half-life of 12 days, and may
persist in nonplasma compartments for as
long as 6 months. Therefore, ribavirin
therapy is contraindicated in women who are
pregnant and in the male partners of women
who are pregnant. At least 2 reliable forms of
effective contraception must be used during
treatment and for 6 months posttreatment.

PATIENT CARE SERVICES
Answer: A
Targeted Objective: Construct an
individualized management plan for both
treatment-naïve and treatment-experienced
patients with HCV infection.
Option B is not correct because the use of Viekira Pak™
is contraindicated with sildenafil. Sildenafil therapy
would need to be held during HCV treatment.
Option C is not correct because sofosbuvir with RBV is a
regimen that is not recommended for GT1 treatmentnaïve patients due to relatively low efficacy compared
to newer agents.
Option D is not correct because boceprevir-based
regimens are no longer recommended for treatment of
HCV due to relatively low efficacy compared to newer
agents. Boceprevir is no longer manufactured.

• In a primarily rural location,
geographical barriers prevent access
to care, including disease screening
Objectives
• Increase HCV screening and utilization
of CVT to link rural Veterans t to
treatment

AASLD/IDSA HCV Guidance
• An anti-HCV test is recommended for HCV testing, and if the
result is positive, current infection should be confirmed by a
sensitive HCV RNA test.
• Among persons at risk of reinfection after previous spontaneous
or treatment-related viral clearance, initial HCV-RNA testing is
recommended because an anti-HCV test is expected to be
positive.
• Quantitative HCV-RNA testing is recommended prior to the
initiation of antiviral therapy to document the baseline level of
viremia (i.e., baseline viral load).

FDA: 2016 Updates
• 02/12/2016
– On February 12, 2016, the FDA approved changes to the Harvoni (ledipasvir
and sofosbuvir) fixed-dose combination label to expand the patient population
to include those with chronic hepatitis C virus genotype 1, infection who are
liver transplant recipients, genotype 4 infection who are liver transplant
recipients without cirrhosis, or with compensated cirrhosis, and genotype 1
infection with decompensated cirrhosis. The major changes to the label are
the following.
• 03/01/2016
– The OLYSIO (simeprevir) label was updated to include pharmacokinetic, safety
and efficacy data in treatment-naïve adult patients of East Asian ancestry with
chronic hepatitis C virus genotype 1 infection. Patients of East Asian ancestry
exhibit higher simeprevir plasma exposures but no dosage adjustment is
required based on race.

FDA: 2015 Updates
• 03/24/2015
– FDA Drug Safety Communication: Harvoni and Sovaldi
• The U.S. Food and Drug Administration (FDA) is warning that serious slowing of the heart rate
can occur when the antiarrhythmic drug amiodarone is taken together with either the hepatitis
C drug Harvoni (ledipasvir/sofosbuvir) or with Sovaldi (sofosbuvir) taken in combination with
another direct acting antiviral for the treatment of hepatitis C infection. We are adding
information about serious slowing of the heart rate, known as symptomatic bradycardia, to the
Harvoni and Sovaldi labels. We are recommending that health care professionals should not
prescribe either Harvoni or Sovaldi combined with another direct acting antiviral, such as the
investigational drug daclatasvir or Olysio (simeprevir), with amiodarone. Patients should not
stop taking any of their medicines without first talking to their health care professionals.
