Pharmacoeconomic Study Assessing the Cost of Chronic Hepatitis C Treatment With Peginterferon Alfa-2b (PegIntron) and Ribavirin (Rebetol) in the Czech Republic (Study P04588)(COMPLETED)

October 1, 2015 updated by: Merck Sharp & Dohme LLC

Cost of Treatment of Chronic Hepatitis C Using Combination of Peginterferon α-2b Plus Ribavirin

The objective of the study is to evaluate the costs associated with peginterferon alfa-2b (PegIntron) plus ribavirin (Rebetol) treatment for chronic hepatitis C in the Czech Republic. Only costs associated with rescue medication, concomitant therapy, disease monitoring, and medical intervention costs recognized by the treating institution as treatment-related expenses will be included in the analysis. The study will also evaluate the correlation between hepatitis C virus (HCV) therapy-related costs with ribavirin dosing and participant history.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Average Cost Per Participant With Sustained Virologic Response (SVR) Stratified by Weight Category
Time Frame: From enrollment up to 48 weeks for participants with hepatitis C virus (HCV) genotype 1, and from enrollment up to 24 weeks for participants with HCV genotypes 2 and 3
SVR is defined as undetectable HCV ribonucleic acid (RNA) six months after the end of treatment. Cost per participant with SVR was calculated as a ratio of the total costs for all participants and the number of participants with SVR in the given group. All costs were adjusted for inflation to 2010 values.
From enrollment up to 48 weeks for participants with hepatitis C virus (HCV) genotype 1, and from enrollment up to 24 weeks for participants with HCV genotypes 2 and 3

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Average Cost Per Participant With SVR Stratified by Ribavirin Dosage
Time Frame: From enrollment up to 48 weeks for participants with HCV genotype 1, and from enrollment up to 24 weeks for participants with HCV genotypes 2 and 3
SVR is defined as undetectable HCV ribonucleic acid (RNA) six months after the end of treatment. Cost per participant with SVR was calculated as a ratio of the total costs for all participants and the number of participants with SVR in the given group. All costs were adjusted for inflation to 2010 values.
From enrollment up to 48 weeks for participants with HCV genotype 1, and from enrollment up to 24 weeks for participants with HCV genotypes 2 and 3
Average Cost Per Participant With SVR Stratified by Prior Treatment Status
Time Frame: From enrollment up to 48 weeks for participants with HCV genotype 1, and from enrollment up to 24 weeks for participants with HCV genotypes 2 and 3
SVR is defined as undetectable HCV ribonucleic acid (RNA) six months after the end of treatment. Cost per participant with SVR was calculated as a ratio of the total costs for all participants and the number of participants with SVR in the given group. All costs were adjusted for inflation to 2010 values.

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
