Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Participants With Chronic Hepatitis C

Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Participants With Chronic Hepatitis C - An Observational Study in Greece

The interferon-free combination regimen of paritaprevir/ritonavir/ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well-controlled conditions.

This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to the local label, under real-world conditions in Greece in a clinical practice patient population.

Detaljert beskrivelse

This was a prospective, multi-center observational study in participants receiving the interferon-free ABBVIE REGIMEN ± RBV. The prescription of a treatment regimen was at the discretion of the physician in accordance with local clinical practice and label, was made independently from this observational study and preceded the decision to offer the participant the opportunity to participate in this study. Adults chronically infected with hepatitis C virus (HCV), receiving the interferon-free ABBVIE REGIMEN, were offered the opportunity to participate in this study during a routine clinical visit at the participating sites. Follow-up visits, treatment, procedures, and diagnostic methods followed physicians' routine clinical practice. Data were collected at the following time windows: baseline, early on-treatment visit, mid-treatment visit (for participants with treatment duration of 24 weeks), end of treatment (EoT), early post-treatment and 12 and 24 weeks after the end of treatment (representing sustained virologic response 12 weeks after the end of treatment [SVR12] and sustained virologic response 24 weeks after the end of treatment [SVR24]).

Tiltaksbeskrivelse
Tidsramme
Percentage of Participants Achieving Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
Tidsramme: 12 weeks after the last actual dose of study drug

SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than 50 IU/mL 12 weeks after the last actual dose of study drug. The core population (CP) consisted of participants who met all inclusion criteria and were adequately treated according to the standard of care and within local label recommendations for their specific disease characteristics (cirrhotic status, genotype). The core population with sufficient follow-up data 12 weeks after the last actual dose of study drug (CPSFU12) was defined as all CP participants who fulfilled one of the following criteria:

  • evaluable HCV RNA data ≥70 days after the last actual dose of the ABBVIE REGIMEN
  • an HCV RNA value ≥50 IU/mL at the last measurement post-baseline
  • HCV RNA <50 IU/mL at the last measurement post-baseline, but no HCV RNA measurement ≥70 days after the last actual dose of the ABBVIE REGIMEN due to reasons related to safety (e.g. dropped out due to AE) or virologic failure
12 weeks after the last actual dose of study drug
