9. Evolving Hepatitis C Therapy Guidelines and Treatment Cascade

The first U.S. hepatitis C treatment guidelines incorporating interferon-free direct-acting antiviral regimens were issued in January 2014 and periodically updated to reflect new drug approvals and emerging data from studies and real-world use. The new therapies have cure rates above 90%, but cost and other barriers have limited their use.

10. Hepatitis C Cures for HIV/HCV Coinfected and Advanced Liver Disease

New interferon-free direct-acting antiviral regimens have high cure rates for chronic hepatitis C patients who were previously considered "difficult to treat," including HIV/HCV coinfected people and patients with liver cirrhosis, decompensated liver disease, and liver transplant recipients. New treatment can now cure a majority of people even with multiple negative predictive factors.

Cured Hepatitis C Patients May Have Same Life Expectancy as General Population

Chronic hepatitis C patients with advanced liver fibrosis or cirrhosis who achieve sustained virological response to treatment have a life expectancy matching that of the general population, according to findings from a retrospective study published in the November 12 Journal of the American Medical Association. Those who were not cured, however, had significantly reduced survival.

Updated Hepatitis C Treatment Guidelines Add New Therapies, Hard-to-Treat Patients

The American Association for the Study of Liver Diseases (AASLD), Infectious Diseases Society of America (IDSA), and International Antiviral Society-USA (IAS-USA) recently updated their hepatitis C treatment guidelines to add newly approved interferon-free direct-acting antiviral regimens and to provide more information about treating patients with HIV/HCV coinfection and decompensated liver disease. The evolving guidelines are available online at HCVguidelines.org.

AASLD 2014: 1 Million People with Hepatitis C in the U.S. Meet High Priority Criteria for Treatment

An estimated 813,000 people with diagnosed hepatitis C in the U.S. have undergone liver disease staging and meet the "highest" or "high" priority criteria for immediate treatment, according to an analysis presented at the American Association for the Study of Liver Diseases (AASLD) Liver Meeting last month in Boston. The number would be even higher if taking into account undiagnosed individuals and prisoners and others excluded from household surveys.

AASLD 2014: ACH-3102 plus Sofosbuvir Cures All Hepatitis C Patients in Phase 2 Study

Achillion's second-generation HCV NS5A inhibitor ACH-3102 combined with sofosbuvir (Sovaldi) was well-tolerated and led to sustained virological response in all treatment-naive genotype 1 hepatitis C patients in a Phase 2 proxy study, according to late-breaking findings presented at the American Association for the Study of Liver Diseases (AASLD) Liver Meetinglast month in Boston. Another early study showed promising results for Achillion's nucleotide polymerase inhibitor ACH-3422.

AASLD 2014: Many Hepatitis C Patients with Cirrhosis or Advanced Fibrosis Face Liver Failure

Nearly one-third of chronic hepatitis C patients with liver cirrhosis and 12% with advanced fibrosis progressed to decompensation within 5 years, and 23% and 11%, respectively, died, according to a study presented at the American Association for the Study of Liver Diseases (AASLD) Liver Meetinglast month in Boston. These findings underscore the urgent need for treatment for such individuals.

AbbVie's Viekira "3D" Combo for Hepatitis C Wins FDA Approval

The U.S. Food and Drug Association this week approved AbbVie's Viekira Pak for people with genotype 1 chronic hepatitis C, including patients with compensated cirrhosis. The regimen -- formerly known as "3D" -- consists of the HCV NS3/4A protease inhibitor paritaprevir, a ritonavir booster, and the NS5A inhibitor ombitasvir in a once-daily coformulation, taken with the twice-daily non-nucleoside HCV NS5B polymerase inhibitor dasabuvir.

AASLD 2014: Sofosbuvir/ Ledipasvir Cures Most Previously Treated HCV Patients with Cirrhosis

Difficult-to-treat hepatitis C patients with liver cirrhosis who were not cured with a prior course of therapy with first-generation HCV protease inhibitors had a sustained virological response rate of 97% when retreated with sofosbuvir/ledipasvir (Harvoni) for 24 weeks, researchers reported at the American Association for the Study of Liver Diseases (AASLD) Liver Meeting last month in Boston. Sofosbuvir/ledipasvir also worked worked well for people previously treated with other sofosbuvir-containing regimens.
