July 20, 2015 updated by: Merck Sharp & Dohme LLC

Evaluation of Compliance of HCV Genotype 1 Infected Patients Receiving PegIntron / Rebetol in Conjunction With a Patient Assistance Program - Non Interventional Observational Study.

Enrolled patients will be recruited to two parallel groups during therapy for Hepatitis C. Patients in the first one will receive a patient assistance program, and patients in the second group will not. All patients will receive PegIntron and Rebetol according to label.

Study Overview

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

All

Sampling Method

Non-Probability Sample

Study Population

The support program consisted of training by physicians or specialized nurses on the significance of treatment compliance, methods for managing adverse events, and correct drug administration, as well as informational materials and assistance in the management of adverse events.
Biological: PegIntron (peginterferon alfa-2b; SCH 54031)
Peginterferon alfa-2b will be administered according to the product's labeling.
Other Names:
  • PegIntron
Drug: Rebetol (ribavirin; SCH 18908)
Ribavirin will be administered according to the product's labeling.
Other Names:
  • Rebetol
Behavioral: Patient Assistance Program

The patient assistance program includes the following:

  • Training by physicians or specialized nurses.
  • Informational materials based on the "To beat HCV" program.
  • Management of specific side effects.
Other Names:
  • Support program
Treatment Alone
PegIntron/Rebetol treatment only.
Biological: PegIntron (peginterferon alfa-2b; SCH 54031)

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
The Number of Participants Who Complete Treatment With PegIntron/Rebetol Therapy for Hepatitis C
Time Frame: At the end of the 48-week treatment period
Participant adherence to therapy was compared between participants treated with PegIntron/Rebetol either with or without a patient assistance program
At the end of the 48-week treatment period
The Number of Participants With a Sustained Virologic Response at 6 Months Post-treatment
Time Frame: Measured at 6 months post-treatment
Sustained virologic response is defined as having an undetectable hepatitis C virus ribonucleic acid (HCV-RNA) at the end of treatment and 6 months post-treatment
Measured at 6 months post-treatment
The Number of Participants Who Relapsed at 6 Months Post-treatment
Time Frame: Measured at end of treatment and 6 months post-treatment
Participants who relapse are defined as having an undetectable HCV-RNA at the end of treatment but detectable HCV-RNA at 6 months post-treatment
Measured at end of treatment and 6 months post-treatment

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 Length of Treatment
Time Frame: Maximum 48-week treatment duration
Participant adherence to therapy was compared between participants who received vs not received a patient assistance program in addition to their PegIntron/Rebetol treatment.
Maximum 48-week treatment duration
Average Dosage of PegIntron
Time Frame: Up to 48-week treatment duration
Dosage of PegIntron was expressed in terms of micrograms of PegIntron received per kilogram of participant's body weight per week
Up to 48-week treatment duration
Average Dosage of Rebetol
Time Frame: Up to 48-week treatment duration
Rebetol dosage was expressed in milligrams per kilogram of body weight per day.
Up to 48-week treatment duration

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

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.
October 1, 2005

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.
