Glossary of Terms

• Viral Load- quantity of virus present in blood– Measured by assay of HCV RNA by polymerase chain

reaction (PCR)

• Genotype- different types of HCV virions (think of cousins) identified as 1,2,3,4,5,6– Subtypes (think of siblings)- 1a,1b,2a,2b,3a,3b

• Response to treatment– SVR- Sustained Virologic Response– Relapse and Breakthrough– Nonresponders- partial and null

Why Treat Chronic Hepatitis C?

• The disease– Common, chronic, and potentially progressive– Complications are becoming more common[1,2]

• Liver failure, HCC

• The treatment– Viral cure, or SVR, is achievable– SVR associated with histologic improvement and gradual

regression of fibrosis[3]

– SVR reduces risk for liver failure and HCC, improves survival[4,5]

Primary Goal of HCV Therapy

• SVR24: undetectable HCV RNA 6 mos after completion of treatment– Considered clinical cure

• Measures of improved outcome– Histologic improvement

• Inflammatory and fibrosis scores

– Portal pressure reduction– Reduction in clinical complications including

HCC– Survival

Page 10: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

We Understand the Rules of the Game With IFN-Based Treatment

• Establishing patient candidacy • Assessing potential drug–drug interactions • Evaluating likelihood of SVR in treatment-

naive and treatment-experienced patients • Applying response-guided treatment

algorithms to maximize response and mitigate treatment failure

• Optimally managing adverse events

Page 11: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

For Genotype 2 or 3, PegIFN/RBV Remains Standard of Care

• Highly effective therapy with higher cure rates than genotype 1

• 24 wks of therapy is recommended[1,2]

– Some patients (with RVR and low baseline HCV RNA) may be treated for 16 wks if therapy poorly tolerated, although relapse rates may be higher[2]

• Future regimens may offer further improvements, such as – Shorter durations– All-oral therapy – Fewer adverse events

Response Guided Therapy

Page 15: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Patients Responding Early Can Achieve High SVR Rates With Shortened Therapy

Response-guided therapy: patients who achieve optimal virologic response at early time points can receive abbreviated therapy without reducing their chance of SVR

Patients eligible for RGT– Boceprevir: noncirrhotic treatment-naive patients, previous relapsers,

and previous partial responders[1,2]

– RGT criterion: must achieve undetectable HCV RNA at Wk 8 (ie, Wk 4 of triple therapy) and maintain it at Wk 24

– Telaprevir: noncirrhotic treatment-naive patients and previous relapsers*[2,3]

– RGT criterion: must achieve undetectable HCV RNA at Wk 4 of triple therapy and maintain it at Wk 12

– Pts with cirrhosis are not eligible for RGT and should have 48 weeks of therapy

Due to AEs

Page 23: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Both BOC and TVR Have Potential for Many Drug–Drug Interactions

• BOC– Strong inhibitor of

CYP3A4/5 – Partly metabolized by

CYP3A4/5– Potential inhibitor of and

substrate for P-gp

• Most drug–drug interactions can be overcome by careful survey of the patient’s medications and judicious substitutions during HCV therapy (or just during the period of PI-based triple therapy)

• TVR– Substrate of CYP3A– Inhibitor of CYP3A– Substrate and

inhibitor of P-gp

Preliminary Real-World Safety Findings: CUPIC—PIs in Patients With Cirrhosis

Page 28: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Summary

• BOC- or TVR-based triple therapy increases SVR rates over pegIFN/RBV alone for all genotype 1 patient populations that have been evaluated

• On-treatment management techniques including application of RGT algorithms and effective management of adverse events maximize treatment outcomes and mitigate treatment failure

• In spite of significant progress using BOC- or TVR-based triple therapy there are several challenging impediments to universal application for HCV patients

Regimens—Many Challenges

For us—lead-in, response-guided therapy . . .

BOC = 12/dayRBV = 4-7/day

TVR = 6/dayRBV = 4-7/day

Page 30: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Challenges of Current PI-Based Therapy

• Efficacy

– Very dependent on the IFN response

• Tolerability

– Additional AEs beyond pegIFN/RBV

• Regimens

– Complicated (lead-in, RGT)/pill burden

• DDIs

– Many with both agents to common drugs

• Genotype/special populations

– Limited activity in non-GT1, limited data HIV/OLTx, ESRD

Treat Now vs Wait: Many Issues to Consider

Treat now•Triple therapy increases SVR•Earlier treatment has higher success rates•Successful treatment may arrest progression of liver disease•Uncertainty about timelines for approval and reimbursement

Defer•First-generation PIs complex, associated with adverse events•Does current treatment failure affect future treatment?•Potential for higher SVR, including in challenging populations•Potential for simpler regimens, QD or BID, fewer adverse effects, eventually IFN-free•Activity in non–genotype 1

Page 40: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Advantages of Future Therapies

• Once-daily dosing• Shorter duration• Simpler regimens—no RGT• Fewer AEs• IFN free• High efficacy

Page 41: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Caveats to Future Therapies

• Very small studies• Potential for toxicity remains

– Agents from multiple classes (nucs, nonnucs, PI, alisporivir) pulled for toxicity

• Efficacy and safety in cirrhosis largely unknown• Minimal data—DDIs, special populations (OLTx, HIV, ESRD)• Timelines uncertain

– Not just approval, but availability and reimbursement

• Costs uncertain, but likely an issue in many regions

HIDING IN PLAIN SIGHT

If this stuff is so good, where are all the patients hiding?

Chronic HCV Infection May Result in Liver Cirrhosis, HCC, and Liver-Related Death

Liver transplant

• HCV is the #1 cause of liver transplant in the United States1

• Up to 45% of patients awaiting liver transplant have HCV2

Liver cancer

• HCV is the leading cause of HCC1

Death

• 4% annual death rate postcirrhosis3

• CDC has identified the number of deaths from HCV now exceed those from HIV4

Fibrosis Cirrhosis Hepatocellular Carcinoma

(with cirrhosis)

The rate of progression of liver fibrosis accelerates as fibrosis advancesand can vary from patient to patient5,6

Studies Have Shown a Decreased Rate of Liver Complications in Patients Who Achieved SVR With

Peg-IFN/RBV*

• The HALT-C Trial was a multicenter study of 1145 subjects with advanced chronic HCV who were nonresponders to previous IFN-based treatment

• The trial found that achieving SVR with Peg-IFN/RBV therapy significantly reduced HCV-associated complications and mortality

Rates of Liver-Related Complications (%)

CDC Guidelines for Screening Baby Boomers

.

The Centers for Disease Control and Prevention (CDC) has created draft guidelines recommending a

one-time anti-HCV antibody test for all baby boomers (those born from 1945 through 1965) in an

effort to identify these undiagnosed individuals

Summary

• Up to 5.2 million persons are living with HCV in the United States

• 75% of infected individuals are not aware of their HCV status

• HCV is a chronic disease and the number of patients estimated to develop serious liver outcomes is projected to peak in 2020, reaching over 1 million cases of cirrhosis

• HCV can be cured in 75% of those treated with today’s medications

• Special attention should focus on diagnosing and referring populations disproportionately affected by HCV, as recommended by the updated CDC guidelines

– 82% of patients with chronic HCV were born from 1945 through 1965

You are at the front line of screening and TREATMENT—identification is the first step in a patient’s chance for a cure

Project ECHOExtension for Community Health Outcomes

An innovative web-based healthcare delivery system developed to treat chronic and complex diseases in rural and underserved areas

through the use of telemedicine technology.

Terry D. Box, MD Director

Susanne M. Cusick Manager

Page 55: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Objectives

• Enhance the capacity of Community providers to effectively treat common chronic, complex diseases in remote and underserved areas

• Bridge the gap between primary providers and specialist to maximize time and expertise

• Teach and disseminate best practices

• Provide case-based CME to Primary Care clinicians

Page 56: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Objectives-cont.

• Reduce Professional Isolation by providing access to a multidisciplinary specialty care team

• Expand access to care by sharing medical knowledge

• Target Clinical conditions that are common, require complex treatment and have impact on health and economics– Hepatitis C Diabetes Child Psychiatry – Asthma Chronic Pain Rheum. Arthritis

Page 57: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

How it Works• Providers are self-identified/recruited to participate

• At each site a lead clinician (MD, NP, PA) is identified to become the local expert

• Site Initiation includes visit from the U of U team to train and assist with tech issues

• Participating providers and staff may visit University to shadow clinicians

Page 58: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

How it Works-cont.

• Weekly web-based “Knowledge Network” for disease management

• Providers present cases to ECHO faculty who mentor the local provider

– Proven success: “Outcomes of Treatment for Hepatitis C Virus Infection by Primary Care Providers”

Sanjeev Arora, M.D., Karla Thornton, M.D., Glen Murata, M.D., et al.

N Engl J Med 2011; 364:2199-2207 June 9, 2011

• Real-time, case based learning– CME: Category 1

Page 59: Chronic Hepatitis C and Project ECHO State of Affairs  Spring 2013

Capacity and Relationship Building

• Virtual Work Force Multiplier– Efficient and effective delivery of University Faculty expertise and

outreach– Collegial interaction with primary providers

• Expertise is developed in primary providers – who teach co-workers and – serve as local consultants for peers in the clinic/region
