An Observational Study Examining the Use of Triple Combination Therapy With Boceprevir, Peginterferon Alfa-2a and Ribavirin in the Re-Treatment of Chronic Hepatitis C Patients

18 de octubre de 2016 actualizado por: Hoffmann-La Roche

Non-interventional Study to Observe Triple Combination Therapy With Boceprevir or Simeprevir Plus Peginterferon Alfa-2a Plus Ribavirin for Re-treatment of Chronic Hepatitis C in Hungary (IMPERIAL)

This prospective, national, multicenter, non-interventional study examined the use of triple combination therapy with boceprevir, pegylated interferon (peginterferon) alfa-2a and ribavirin in re-treating participants with genotype 1 chronic hepatitis C (CHC) infection. Dosing and treatment duration were at the discretion of the investigator in accordance with local clinical practice and local labeling. Participants were to be observed for the duration of their triple combination therapy and for up to 24 weeks thereafter.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Sustained Virological Response 24 (SVR24) Rate
Periodo de tiempo: 24 weeks after end of treatment (EOT) at Week 72
The SVR 24 rate is defined as percentage of participants with Hepatitis C virus (HCV) Ribonucleic Acid (RNA) less than 15 international unit/milliliter (IU/mL) after the 24-weeks follow-up.
24 weeks after end of treatment (EOT) at Week 72

Medidas de resultado secundarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Percentage of Participants With Virological Response
Periodo de tiempo: Weeks 4, 8, 12, and 24
Virological response is defined as HCV RNA <15 IU/mL.
Weeks 4, 8, 12, and 24
Number of Participants With Virological Breakthrough
Periodo de tiempo: Up to Week 48
Virological breakthrough is defined as either HCV RNA >=15 IU/mL in participants with prior virological response or as an increase in HCV RNA >/=1 log10 above nadir.
Up to Week 48
Number of Participants With Virological Relapse
Periodo de tiempo: Week 49 up to Week 72
Virological response is defined as HCV RNA >/=15 IU/mL during the treatment free follow-up period in participants with virological response at the end of treatment.
Week 49 up to Week 72
Number of Participants With Treatment Discontinuation Due to Futility
Periodo de tiempo: Up to Week 48
Treatment discontinuation due to futility is defined as HCV RNA drop <3 log10 at Week 8, HCV RNA >/=100 IU/mL at Week 12, or HCV RNA >/=15 IU/mL at Week 24.
Up to Week 48
Number of Participants With Treatment Discontinuation
Periodo de tiempo: Up to Week 48
Treatment discontinuation is reported by sub-categories of reasons for treatment discontinuation. Futility rule is defined as HCV RNA drop <3 log10 at Week 8, HCV RNA >/=100 IU/mL at Week 12, or HCV RNA >/=15 IU/mL at Week 24.
Up to Week 48
Number of Participants With Adverse Events
Periodo de tiempo: Up to 72 weeks
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Up to 72 weeks
Percentage of Participants With Positive Predictive Value of Participant Demographics for SVR Rate
Periodo de tiempo: Screening (before Week 1)
Demographic characteristics recorded were age and gender. Predictive value of these characteristics for SVR rate was to be assessed.
Screening (before Week 1)
Percentage of Participants With Positive Predictive Value of Liver Fibrosis
Periodo de tiempo: Screening (before Week 1)
The following sub-categories of liver fibrosis were determined in this study: 1) no cirrhosis, 2) bridging fibrosis and 3) cirrhosis. Predictive value of these sub-categories of liver fibrosis for SVR rate was to be assessed.
Screening (before Week 1)
Predictive Value of HCV Disease Characteristics
Periodo de tiempo: Screening (before Week 1)
HCV disease characteristics evaluated were HCV genotype (subtype), including HCV 1(a) and HCV 1(b). Predictive value of these disease characteristics for SVR rate were to be assessed.
Screening (before Week 1)
Percentage of Participants With Positive Predictive Value of Previous Virological Response (Null-response, Partial Response, or Relapse)
Periodo de tiempo: Up to 72 weeks
Previous virological response was sub-categorized into the following categories: null-response, partial response, or relapse. Predictive value of these sub-categories for SVR rate were to be assessed.
Up to 72 weeks
