Quantification of Side Effects During Hepatitis C Therapy

Status Completed

Clinical Trial Summary

This study aims to assess the frequency and severity of adverse events during Hepatitis C therapy with or without first generation protease inhibitors.

Clinical Trial Description

Hepatitis C Virus infection is one of the main causes of chronic liver disease worldwide with current estimates of approximately 130 - 210 million individuals (according to 3% of the world population) chronically infected with the hepatitis C virus. However, hepatitis C virus infections are among the most common causes leading to chronic hepatitis, liver cirrhosis and liver related death worldwide.

The current standard of care is a combination of pegylated Interferon and Ribavirin (dual-therapy). Since 2011, direct-acting antiviral drugs inhibiting viral protease are approved as an addition to the standard therapy (triple-therapy).

The occurrence of adverse events as well as their severity generally depends on the therapy regimen and is influenced by type and dosage of medications.

Most common adverse events (affects up to 95% of patients) are fever, fatigue, headache, nausea, arthralgia, depression, skin reactions, neutropenia, and anemia.

A more frequent occurrence of adverse events with triple-therapy compared to dual- therapy has become clear since it's introduction, particularly with regard to anemia, neutropenia, gastrointestinal discomfort, fatigue, dysgeusia, and skin reactions. How- ever, there is accumulating evidence for a more often appearance of infections and/or infestations in patients receiving triple-therapy.

The medical consequence from adverse events is a reduction of quality of life and consecutively the loss of antiviral therapy adherence. Thus, early recognition and immediate treatment of adverse events are crucial aspects in the success of antiviral treatment.

Aim of this study is to quantify reported adverse events with respect to therapy reg- imen (dual-therapy vs. triple-therapy) in patients who are treated at the Department of Internal Medicine, Division of Gastroenterology and Hepatology at the Medical University Graz. Furthermore, a detailed review of international treatment recommendations, as well as an analysis of possible predictor parameters for the appearance of adverse events and treatment success is done. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
