Birth Cohort Screening and DAA Tx
Could Greatly Reduce HCV-Related
Transplants
 Markov model[1] based on birth cohort developed to predict transplant rate[2]
 Assumptions in model: All stages of fibrosis treated at same rate; 90% response rate to new Tx; all pts
with decompensated cirrhosis or HCC within Milan criteria considered potential transplant candidates

Fibrosis Assessment:
Important to Diagnose Cirrhosis
 AASLD/IDSA guidance
 An assessment of the degree of hepatic fibrosis, using
noninvasive testing or liver biopsy, is recommended (rating:
Class I, Level A)
 Fibrosis assessment used to determine treatment urgency if
limited resources prevent treatment of all cases of HCV
infection and need for additional screening
 Cirrhotic patients require regular screening for HCC,
varices, other complications
 Achieving SVR in cirrhotic HCV pts highly beneficial
AASLD/IDSA HCV Management Guidance. October 2014.
Options for Liver Fibrosis Assessment
Liver biopsy:
gold standard
Liver Biopsy
Serum markers
of fibrosis
Serum
Biomarkers
Elastography:
approved in
United States
Axial CT/MRI, US
can demonstrate
cirrhotic
morphology, portal
hypertension
Strategies for Noninvasive Fibrosis Assessment
 AASLD/IDSA guidance[1]
 Most efficient strategy combines direct serum biomarkers and
transient liver elastography[2]
 Consider biopsy for any patient with discordant results between
2 testing methods if the information will affect clinical decisions
 Persons with clinical evidence of cirrhosis do not require
further disease staging
1. AASLD/IDSA HCV Management Guidance. October 2014.
2. Boursier J, et al. Hepatology. 2012;55:58-67.
AASLD/IDSA: Patients With F3/F4 Fibrosis
Have Highest Priority for HCV Treatment
 Treatment recommended for all patients with chronic HCV
infection (rating: Class I, Level A)
 When constrained resources prevent treatment of all HCV
infection cases, highest priority should be given to patients
with advanced fibrosis (Metavir F3) or compensated cirrhosis
(Metavir F4), liver transplant recipients, and patients with
severe extrahepatic hepatitis C
 Based on available resources, treatment should be prioritized
as necessary so that patients at high risk for liver-related
complications and severe extrahepatic hepatitis C
complications are given high priority

Simeprevir
 Oral, once-daily NS3 PI for GT1 HCV
 Improved adverse effect profile vs previous PIs: no anemia
 Fewer drug–drug interactions vs previous PIs: no meaningful
drug–drug interactions with tacrolimus
 No data yet in CTP class B/C pts, but higher simeprevir
exposure in CTP class B/C individuals without HCV
infection makes dosing problematic
 Approved for combination treatment of GT1 HCV
 Screening for Q80K in GT1a pts recommended

Opportunities and Challenges With Current
Therapies in GT1 Cirrhosis
 Higher SVR rates in GT1 HCV with compensated cirrhosis
with just 12 wks of therapy with sofosbuvir + pegIFN/RBV
than with first-generation protease inhibitors
 No adjustment of sofosbuvir required
 Adverse effects of pegIFN/RBV still problematic in cirrhotics
 All oral therapy now available for patients with GT1 HCV
with 2 different regimens
 Sofosbuvir/ledipasvir
 Sofosbuvir + simprevir ± RBV
 Based on limited data in F3/F4 disease (39 patients)
 Viral suppression associated with clinical improvement

Anticipated Changes in HCV Therapy
 All-oral regimens will be the standard of care by end of 2014
for all genotypes
 Excellent efficacy in pts with compensated cirrhosis
 More data required in pts with decompensated cirrhosis
On-Treatment Monitoring:
GT1 With Cirrhosis
 Safety data from phase II/III studies suggest no difference in monitoring required for
patients with CTP class A cirrhosis
 Assessments for drug-related adverse events should be conducted more frequently if

Triple DAA Therapy With Paritaprevir/
Ritonavir/Ombitasvir + Dasabuvir + RBV
 Paritaprevir is a potent NS3/4A protease inhibitor
 Ritonavir boosting of paritaprevir increases the peak, trough,
and overall drug exposures of paritaprevir to enable once-daily
dosing
 Ombitasvir is a potent NS5A inhibitor
 Dasabuvir is a nonnucleoside NS5B polymerase inhibitor

 Treatment: 12 or 24 wks of sofosbuvir/ledipasvir plus RBV (escalating doses

 Tx-emergent SAEs occurred in 28 patients (26%)
 4 SAEs in 4 pts deemed related to study treatment: anemia, decreased hemoglobin,
hepatic encephalopathy, peritoneal hemorrhage
 Most common AEs: fatigue, nausea, headache
 SVR4 rates among patients with available data
 CTP B: 89% with 12 wks, 92% with 24 wks

Management of HCV With Cirrhosis: Summary
 All oral therapies for patients with GT1 HCV infection
approved in 2014
 > 90% SVR rate, 12- to 24-wk duration
 Cirrhosis: some treatment-experienced patients require
24 wks of treatment
 Interferon not required
 RBV-free therapies now available
 More data needed in decompensated liver disease
 GT2: High SVR rates regardless of cirrhosis
 GT3: High SVR rates in treatment-naive patients
 Additional strategies needed for cirrhotic nonresponders
