About this study

Official title: A Phase 3, Randomized, Open-Label Study of the Safety and Efficacy of Two Dose Levels of Interferon Alfacon-1 (Infergen, CIFN) Plus Ribavirin Administered Daily for 48 Weeks Versus No Treatment in Hepatitis C Infected Patients Who Are Nonresponders to Previous Pegylated Interferon Alfa Plus Ribavirin Therapy

This Phase 3 clinical study is designed to evaluate the safety, tolerability, and efficacy of two dose levels of Infergen (interferon alfacon-1, CIFN) plus Ribavirin administered daily for 48 weeks and no treatment in patients chronically infected with hepatitis C who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy.

Patients are randomized 1:1:1 to receive Interferon Alfacon-1 (9 or 15 µg) + Ribavirin (both administered daily) or no treatment for up to 48 weeks.

The protocol and informed consent form that will be used must be approved by the Investigator's Institutional Review Board (IRB)/Independent Ethics Committee (IEC) before the study is initiated.

Being tested
Daily Infergen (Interferon Alfacon-1, CIFN) (9 or 15 µg) + Ribavirin (1000-1200 mg, based on body weight) PO Daily for up to 48 wks

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Daily Infergen (Interferon Alfacon-1, CIFN) (9 or 15 µg) + Ribavirin (1000-1200 mg, based on body weight) PO Daily for up to 48 wksDrug

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Evaluate sustained virologic response (SVR) rate of daily Infergen at two dose levels plus ribavirin and no treatment in chronically HCV-infected patients who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy.

Secondary outcomes (1)
  1. Evaluate safety & tolerability of therapy detailed in primary objective, and proportion of patients with (a) undetectable plasma HCV RNA levels at weeks 24 & 48 (b) abnormal baseline serum ALT levels that are normal at week 24, week 48 and weeks 48 & 72.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Daily Infergen (Interferon Alfacon-1, CIFN) (9 or 15 µg) + Ribavirin (1000-1200 mg, based on body weight) PO Daily for up to 48 wks in people with Chronic Hepatitis C, run by Bausch Health Americas, Inc..

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 10 inclusion and 28 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 25 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Evaluate sustained virologic response (SVR) rate of daily Infergen at two dose levels plus ribavirin and no treatment in chronically HCV-infected patients who are nonresponders to previous pegylated interferon alfa plus ribavirin therapy.. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 25 Nov 2019.
