3 Rationale for Treating Patients With Advanced Liver Disease
Poor prognosis for HBV-infected patients with decompensated cirrhosis without treatment Increased risk of hepatocellular carcinoma and death[1] Estimated 5-yr survival rate: 14%[2] Liver transplant is effective treatment, but ongoing shortage of donor organs and many patients on waitlists Antiviral agents able to effectively and safely suppress HBV replication in this population, leading to improvement or stabilization of liver function[1] HBV, hepatitis B virus. 1.

4 Approved Agents for the Treatment of Chronic HBV Infection
7 agents approved for first-line treatment of chronic HBV infection Adefovir, entecavir, interferon alfa-2b, lamivudine, peginterferon alfa-2a, telbivudine, and tenofovir 3 agents recommended as first-line therapy according to major liver disease organizations because of their rapid onset of action, low rate of drug resistance with prolonged use, and generally favorable safety profiles[3,4] Entecavir, peginterferon alfa-2a, and tenofovir Peginterferon contraindicated in patients with decompensated liver disease because of risk of worsening liver disease and infectious complications[3-5] Therefore, HBV clinicians must chose between entecavir and tenofovir for treatment of decompensated cirrhosis HBV, hepatitis B virus. 3.

5 Tenofovir for Treatment of CHB Patients With Decompensated Cirrhosis
Tenofovir studied in a limited number of subjects with CHB-associated decompensated cirrhosis Currently no formal indication for the use of tenofovir in patients with decompensated liver disease Both tenofovir and decompensated liver disease may affect renal function Therefore, the contribution of tenofovir to renal impairment in this population is difficult to ascertain Risk of lactic acidosis noted in package insert from experience with HIV but no data on lactic acidosis with tenofovir for HBV CHB, chronic hepatitis B; HBV, hepatitis B virus. Tenofovir [package insert]. January 2012.

10 Entecavir for Treatment of CHB Patients With Decompensated Cirrhosis
Virologic, biochemical, serologic, and safety data available from adult subjects with chronic HBV infection and decompensated liver disease These data led to an indication for use of entecavir in adult patients with decompensated liver disease Dose should be increased to 1.0 mg/day in patients with CrCl ≥ 50 mL/min Appropriate dose adjustments recommended if CrCl < 50 mL/min Patients with decompensated liver disease treated with entecavir may be at higher risk for lactic acidosis CHB, chronic hepatitis B; CrCl, creatinine clearance; HBV, hepatitis B virus.

19 Choice of Agent in Decompensated Cirrhotics With LAM Resistance
ETV monotherapy not a recommended strategy for patients with LAM resistance due to increased risk of ETV resistance over time in this population[20] Guidelines recommend adding or switching to TDF[21,22] Therefore, TDF may be preferred in decompensated cirrhotic patients with LAM-resistant HBV infection Small pilot study showed combination therapy with ETV plus TDF effective and well tolerated in CHB patients with decompensated cirrhosis[23] CHB, chronic hepatitis B; ETV, entecavir; LAM, lamivudine; TDF, tenofovir. 20. Sherman M, et al. Hepatology. 2008;48: Lok AS, et al. Hepatology. 2009;50: EASL. J Hepatol. 2012;[Epub ahead of print]. 23. Amarapurkar D. EASL Abstract 901.

20 Summary: Choice of Agent for CHB Patients With Decompensated Cirrhosis
Tenofovir Entecavir Limited data supporting efficacy and safety No specific indication in this population May be preferred in patients with lamivudine resistance Concerns regarding nephrotoxicity Risk of lactic acidosis, as with all nucleoside analogues More extensive data supporting efficacy and safety Specific indication in this population at 1.0 mg/day Risk of lactic acidosis specifically studied and reported in this population CHB, chronic hepatitis B.

21 Special Considerations When Managing HBV Tx in Decompensated Cirrhotics
Higher rate of serious hepatic adverse events observed in this population, particularly in those with CTP class C disease, compared with rates in patients with compensated liver function Therefore, clinical and laboratory parameters should be closely monitored in this patient population On-treatment monitoring every 3 mos Monitor renal function before and during therapy Adjust dosing frequency of entecavir and tenofovir per manufacturer’s recommendations as needed Therapy for patients with cirrhosis should be long term Decompensated patients who undergo HBeAg seroconversion still might develop HCC or have progression of liver disease Continue therapy until HBV DNA undetectable and patient has lost HBsAg CTP, Child-Turcotte-Pugh; HBeAg, hepatitis B e antigen; HBV, hepatitis B virus; HCC, hepatocellular carcinoma; Tx, treatment.
