Effectiveness and Safety of Direct-Acting Antiviral Agents for the Treatment of Chronic Hepatitis C

Clinical trials evaluating DAA have shown excellent rates of SVR and good safety profiles in patients with CHC infection. Real world data from TARGET, TRIO, IFI, DHCR, DALTON-C, as well as those cohorts from Japan, Taiwan and Korea further confirmed clinical trial findings of DAA in routine practice where populations are more complex. However, these populations are different from Chinese for different host and virus characteristics which limit the applicability of results to local practice. As DAA launched in China since 2017, the availability of INF free DAA treatment will likely lead to better treatment outcome in routine practice, but there are currently no data available to test the hypothesis. In clinical practice, the uptake of DAA regimen will depend on a combination of physician preference, patient's characteristics and drug access. This study will also identify how these three variables affect DAA regimen uptake. This study to 1) characterize pts receiving IFN free DAA regimens, 2) represent common practice in China, 3) describe outcome of various INF free DAA therapy, and 4) confirm registration study results.
