What are the factors that influence the choice of treatment for HCV?
For treatment-naïve adults with chronic HCV genotype 1 infection, the main factors that influence the choice and duration of therapy are (1) presence or absence of cirrhosis, and (2) medication cost or insurance considerations. In the case of elbasvir-grazoprevir use, the HCV genotype 1 subtype (1a or 1b) is also important, as the presence of specific baseline NS5A RASs significantly reduces SVR12 rates in persons with HCV genotype 1a. [ 10, 11, 12] In cases where the genotype 1 subtype is not known, the individual should be treated as HCV genotype 1a. The baseline HCV RNA level generally does not influence the treatment choice or duration, except in treatment-naïve noncirrhotic patients in whom 8 or 12 weeks of ledipasvir-sofosbuvir is being considered. [ 13] Additional data from the HCV-TARGET registry and the Veterans Affairs National Healthcare System demonstrated comparable SVR rates of 94 to 98% for adults without cirrhosis treated with either 8 or 12 weeks of ledipasvir-sofosbuvir if the baseline HCV RNA levels were less than 6 million IU/mL. [ 14, 15, 16] In addition to the factors noted above, drug interactions may also influence the choice of therapy, particularly for individuals with HIV coinfection who are taking antiretroviral medications. Of note, individuals with HCV and HIV coinfection, depending on their specific antiretroviral therapy, are eligible for most of the same regimens for initial treatment of genotype 1 as for persons with HCV monoinfection, except that persons with HIV should not receive (1) any 8-week option of ledipasvir-sofosbuvir, or (2) the 8-week option of glecaprevir-pibrentasvir if cirrhosis is present. [ 11, 12, 17, 18]
What are the factors that affect the choice of treatment for HCV genotype 1?
For individuals with chronic HCV genotype 1 infection, the main factors that influence the choice and duration of therapy are cirrhosis status and prior treatment experience . With the use of certain regimens for persons with HCV genotype 1a, namely elbasvir-grazoprevir, the genotype 1 subtype (1a or 1b) also impacts the choice of therapy, as elbasvir-grazoprevir is only recommended for persons with HCV genotype 1a who do not have baseline NS5A resistance-associated substitutions (RASs). In addition, the HCV RNA level and the patient’s HIV status can impact the duration of ledipasvir-sofosbuvir, but does not affect the duration of other regimens. Finally, the cost of the regimen, insurance coverage, and provider preference can play a major role in the regimen choice. The following treatment recommendations are based on the AASLD-IDSA HCV Guidance for initial treatment of adults with HCV genotype 1 and for retreatment of adults in whom prior therapy failed, including those with HCV genotype 1. [ 4, 5]
What is the AASLD-IDSA HCV guidance?
The following is a summary of the AASLD-IDSA HCV Guidance for adults with HCV genotype 1 infection who are treatment experienced and failed prior DAA therapy , including those without cirrhosis and those with compensated cirrhosis. [ 5, 28, 29, 30] For individuals with cirrhosis, the AASLD-IDSA HCV Guidance defines compensated cirrhosis as Child-Turcotte-Pugh class A and decompensated cirrhosis as Child-Turcotte-Pugh class B or class C. The AASLD-IDSA HCV Guidance for retreatment is no longer genotype specific, but instead emphasizes a pangenotypic approach to retreatment based on the prior treatment regimen. In addition, the AASLD-IDSA HCV Guidance no longer includes recommendations for the retreatment of persons who experienced prior treatment failure with interferon-based therapy, including interferon plus first-generation protease inhibitors ( telaprevir, boceprevir ); these individuals have robust cure rates with modern DAA regimens similar to that observed with treatment-naïve persons. The recommended regimens in the tables below are based on prior regimen failure and listed by evidence level; when the evidence level is considered equivalent, the regimens are listed alphabetically.
