About this study

Official title: A Double-Blind, Placebo-controlled Phase II Study to Assess the Efficacy and Safety of Romiplostim, Administered Once Weekly to Thrombocytopenic Hepatitis C (HCV) Infected Subjects Who Are Not Candidates for Antiviral Treatment With Pegylated Interferon and Ribavirin Due to Persistent Thrombocytopenia

RATIONALE: Romiplostim may cause the body to make platelets.

PURPOSE: This randomized phase II trial is studying how well romiplostim works in treating hepatitis C-infected patients with thrombocytopenia.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess the platelet count response to administration of weekly romiplostim patients with HCV infection whose initial platelet count is < 70,000/L.

SECONDARY OBJECTIVES:

  1. To assess the safety and tolerability of romiplostim the treatment of patients with HCV infection and thrombocytopenia; including physical symptoms and findings, hematologic, serum chemistries and liver function tests and adverse events.

II. To assess the ability of romiplostim to enable subjects to achieve a platelet count sufficient to start antiviral therapy.

III. To assess the ability of romiplostim to maintain platelet counts greater than 50,000/L while receiving antiviral therapy with pegylated interferon and ribavirin.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive romiplostim subcutaneously once weekly for 8 weeks in the absence of disease progression or unacceptable toxicity.

Arm II: Patients receive placebo subcutaneously once weekly for 8 weeks. Patients failing to achieve a platelet count of > 100,000/L cross over to arm I.

Patients achieving a platelet count of > 100,000/L at 8 weeks receive PEG-interferon alfa-2a subcutaneously once weekly and oral ribavirin once daily. Treatment repeats every 7 days for 24-48 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed at 4 and 36 weeks.

Being tested
romiplostim, ribavirin, placebo, PEG-interferon alfa-2a, laboratory biomarker analysis

What is being measured

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

  1. Mean platelet count for actively treated and placebo treated subjects

    Measured: Weeks 6-8

Secondary outcomes (5)
  1. Incidence of adverse events, including clinically significant changes in laboratory values and the incidence of antibody formation

    Measured: Weeks 1-24

  2. Number of subjects in each treatment group who achieve a platelet count of greater or equal to 100,000/L

    Measured: Week 8

  3. Number of patients originally receiving active treatment who maintain a platelet count &gt; 50,000/L while receiving anti-viral therapy with pegylated interferon and ribavirin

    Measured: Weeks 9-24

  4. Changes in plasma HCV viral load during treatment with romiplostim alone

    Measured: Weeks 1-8

  5. Incidence of sustained viral response achieved during treatment with anti-viral therapy in combination with romiplostim

    Measured: Weeks 9-24

Timeline

Why it stopped: Approval of several new agents for the treatment of HCV infection would mitigate the future need for interferon HCV treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing romiplostim, ribavirin and PEG-interferon alfa-2a in people with Hepatitis C Infection and Thrombocytopenia, run by University of Southern California at 1 site in United States.

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 11 inclusion and 15 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: stopped early, as of the sponsor's last update on 11 Apr 2017. 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 United States. 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. Some participants in this study may receive a placebo. 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 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 was stopped early (reason given: Approval of several new agents for the treatment of HCV infection would mitigate the future need for interferon HCV treatment). Results are not available in the source record.

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?

Mean platelet count for actively treated and placebo treated subjects (time frame: Weeks 6-8). 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 11 Apr 2017.
