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

SVR12 was defined as plasma hepatitis C virus (HCV) ribonucleic acid (RNA) level ˂50 IU/mL 12 weeks after end of treatment (EoT) (defined as after last actual dose of the ABBVIE REGIMEN [paritaprevir/ritonavir - ombitasvir ± dasabuvir] or ribavirin [RBV]).

Virologic response is defined as HCV RNA level <50 IU/mL.

Premature study drug discontinuation was defined as participants who prematurely discontinued study drug (ABBVIE REGIMEN or RBV) and who experienced no on-treatment virologic failure (defined as breakthrough [at least 1 documented HCV RNA ˂50 IU/mL followed by HCV RNA ≥50 IU/mL during treatment] or failure to suppress [each measured on-treatment HCV RNA value ≥50 IU/mL]).

For a participant to be include in this analysis, the participant needed to meet each and any of the following SVR12 non-response categories:

• On-treatment virologic failure (breakthrough [defined as at least one documented HCV RNA <50 IU/mL followed by HCV RNA ≥50 IU/mL during treatment] or failure to suppress [each measured on-treatment HCV RNA value ≥50 IU/mL]);
• Relapse (defined as HCV RNA <50 IU/mL at actual EoT followed by HCV RNA ≥50 IU/mL post-treatment for participants who completed treatment [not more than 7 days shortened]);
• Premature study drug discontinuation with no on-treatment virologic failure;
• Missing SVR12 data and/or none of the above criteria (including participants with missing SVR12 data).

Abbreviations: EoT=end of treatment.

Relapse was defined as confirmed HCV RNA <50 IU/mL at EoT or at the last on-treatment HCV RNA measurement followed by HCV RNA ≥50 IU/mL post-treatment in participants who were treated.

Relapse was defined as confirmed HCV RNA <50 IU/mL at EoT followed by HCV RNA ≥50 IU/mL post treatment in participants who completed treatment (actual duration of ABBVIE REGIMEN is not shortened more than 7 days) and had HCV RNA results available in the SVR12 window.

Viral breakthrough was defined as at least 1 documented HCV RNA <50 IU/mL followed by HCV RNA ≥ 50 IU/mL during treatment.

On-treatment virologic failure was defined as breakthrough (at least 1 documented HCV RNA <50 IU/mL followed by HCV RNA≥ 50 IU/mL during treatment) or failure to suppress (each measured on-treatment HCV RNA value ≥50 IU/mL).

RVR4 was defined as HCV RNA < 50 IU/mL at Week 4.

SVR24 was defined as HCV RNA < 50 IU/mL 24 weeks after EoT. During the course of the study, standard of care was changing and it was no longer common practice to assess SVR24.

The EQ-5D-5L is a 2-part instrument for use as a measure of health outcome, designed for self-completion by participants. The 5 items in the questionnaire comprise 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) each of which are rated on 5 levels of severity (1: indicating no problem, 2: indicating slight problems, 3: indicating moderate problems, 4: indicating severe problems, 5: indicating extreme problems), and a separate VAS. The higher the score, the worse the quality of life. For the VAS, the higher the score, the better the quality of life. Participant responses to the EQ-5D-5L were used to generate a health status index (HSI). HSI ranges is anchored at 0 (dead) and 1 (full health).

Co-morbidities/co-infections were defined as hepatitis C virus (HCV) co-infections (human immunodeficiency virus [HIV] or hepatitis B virus [HBV], tuberculosis, schistosomiasis), liver/chronic hepatitis C (CHC) related co-morbidities (liver transplantation, hepatocellular carcinoma, non-alcoholic steatosis, alcoholic liver disease, primary biliary cirrhosis, auto-immune hepatitis, Wilson disease, cryoglobulinemia, porphyria cutanea tarda, auto-immune skin disease), and other co-morbidities (chronic kidney disease, psychiatric disorders, diabetes mellitus, insulin resistance, metabolic syndrome, lipid disorder, cardiovascular disease, immunologically mediated disease, hyper-/hypothyroidism, hemophilia, Thalassemia, sickle cell anemia, V. Willebrand disease, psychoactive substance dependency, kidney transplant, or other).

This includes all participants that took at least 1 concomitant medication from the time when the decision was made to initiate treatment with the ABBVIE REGIMEN until after the last dose.
