About this study
Official title: The Response and Outcomes of Pegylated Interferon Plus Ribavirin Combination Therapy for Chronic Hepatitis C Patients Concomitant With Malignancy Other Than Hepatocellular Carcinoma
Combination therapy with pegylated interferon-alpha plus ribavirin has greatly improved the treatment efficacy and is the mainstream of treatment for chronic hepatitis C infection. The efficacy and safety of pegylated interferon-alpha plus ribavirin combination therapy and its impact on the outcome in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma deserve to be elucidated.
The purposes of this study are:
- To evaluate the efficacy and safety of pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma, compare to those without systemic malignancy.
- To investigate the role of baseline and on-treatment factors on the response to pegylated interferon-alpha 2a plus ribavirin combination therapy in chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma.
Read the detailed description
A prospective, hospital-based study enrolling 40 chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma and other sex- and age-matched 80 chronic hepatitis C patients without malignancy will be conducted. The 40 chronic hepatitis C patients concomitant with malignancy other than hepatocellular carcinoma will receive pegylated interferon-alpha 2a plus ribavirin combination therapy at remission phase after oncological treatments and/or interventions. The other 80 chronic hepatitis C patients without malignancy receiving the same antiviral therapy will serve as controls. The primary outcome measurement is sustained virological response and safety, whilst the secondary measurement is rapid virological and early virological response.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing pegylated interferon alpha 2a and plus ribavirin in people with Chronic Hepatitis C and Neoplasms, run by Kaohsiung Medical University Chung-Ho Memorial Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Efficacy - Sustained virological response (SVR), HCV RNA seronegative by PCR throughout 24-week off-treatment period. (time frame: 1.5 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00630084, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Sep 2015.
