About this study

Official title: A Phase l b/II a, Multicenter, Randomized, Double-Blinded, and Placebo-Controlled Study of the Antiviral Activity, Safety, Tolerability, and Pharmacokinetics of Multiple Ascending Doses of VCH-222 in Subjects With Chronic Hepatitis C-Infection

The purpose of this study is to assess antiviral activity when administered alone for 3 days or in combination with peginterferon and ribavirin for 12 weeks. This study will also evaluate the safety and tolerability of treatment with VCH-222 when given alone or in combination with peginterferon and ribavirin.

The study will also evaluate the pharmacokinetic profile of VCH-222 in HCV infected subjects.

What is being measured

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

  1. To assess the antiviral activity of VCH-222, in subjects with genotype 1 hepatitis C virus (HCV) infection after once (QD) or twice (b.i.d.) daily dosing for 3 days (Part A)

    Measured: Daily for the first 3 days and at each study visit

  2. To assess the antiviral activity of VCH-222, in subjects with genotype 1 HCV infection after b.i.d. daily dosing for 12 weeks in combination with Peg-interferon-alfa-2a and ribavirin (Part B)

    Measured: Week 4 and Week 12

  3. Assess the safety and tolerability of VCH-222 when administered in combination with Peg-IFN-alfa-2a/RBV for 12 weeks (Part B)

    Measured: Study visits throughout part B

Secondary outcomes (2)
  1. To assess the safety and tolerability of VCH-222 when administered for 3 days in monotherapy (Part A)

    Measured: Study visits throughout Part A

  2. To evaluate the pharmacokinetic (PK) profile of VCH-222 in HCV infected subjects (Part B)

    Measured: Time points through Part B

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing peginterferon alfa-2a and ribavirin in people with Hepatitis C, run by Vertex Pharmaceuticals Incorporated at 10 sites in 4 countries.

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 6 inclusion and 3 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 10 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States, Canada, Argentina, Puerto Rico. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

To assess the antiviral activity of VCH-222, in subjects with genotype 1 hepatitis C virus (HCV) infection after once (QD) or twice (b.i.d.) daily dosing for 3 days (Part A) (time frame: Daily for the first 3 days and at each study visit). The study lists 3 primary outcomes in all. 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 NCT00911963, which also lists 1 linked publication.

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 10 Mar 2014.
