About this study

Official title: Multicenter Open-label Observation Program in Patients With Chronic Hepatitis C and With Chronic Renal Failure (CRF) Receiving Peginterferon Alpha-2a (40 kDa) Pegasys

This single arm study will assess the efficacy and safety of PEGASYS in patients with chronic hepatitis C and end-stage renal disease, including patients on hemodialysis. Patients will receive PEGASYS at a dose of 180 micrograms weekly; those with a calculated glomerular filtration rate of <15mL/min will receive a reduced dose of 135 micrograms weekly. Following 48 weeks of treatment there will be a 24 week period of treatment-free follow-up. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

What is being measured

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

  1. Percentage of Participants Achieving Sustained Virologic Response at 24 Weeks Following Treatment Completion

    Sustained virologic response is defined as undetectable Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) levels (<50 international units [IU]/mL) at 24 weeks following the completion of 48 weeks treatment period (Week 72).

    Measured: At Week 72

  2. Percentage of Participants With Undetectable Hepatitis C Virus Ribonucleic Acid Level at Week 24 and Week 48

    HCV RNA level less than 50 IU/mL was considered to be undetectable.

    Measured: At Week 24 and Week 48

  3. Percentage of Participants With At Least a 2log10 Drop in Hepatitis C Virus Ribonucleic Acid at Week 24 as Compared to Baseline

    The table below shows the percentage of participants with at least 2log10 drop in HCV RNA level at Week 24 as compared to Baseline (Screening visit [Days -30 to -1]).

    Measured: From Baseline (Days -30 to -1) and Week 24

Secondary outcomes (5)
  1. Number of Participants Who Experienced Any Adverse Events or Serious Adverse Events

    An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect

    Measured: Up to Week 72

  2. Number of Participants Who Prematurely Withdrew From the Treatment Over a Period of 48 Weeks

    Participants who prematurely withdrew from the treatment for the following reasons: personal reasons (not related to the study), adverse events, and drug unavailability, are presented.

    Measured: Up to Week 48

  3. Number of Participants With Any Marked Abnormality in Laboratory Parameters Over a Period of 72 Weeks

    Marked abnormal laboratory parameters included serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), gamma-glutamyl transpeptidase (GGTP), total bilirubin, alkaline phosphatase (ALP), ferritin and transferrin saturation. These laboratory parameters were evaluated at Baseline (Screening visit [Days -30 to -1]) and at various Visits (V): Week 0 (V1), Week 2 (V2), Week 4 (V3), Week 12 (V4), Week 24 (V5), Week 36 (V6) and Week 48 (V7) and after treatment completion at follow-up (FU) Week 4 (Week 52, V8), FU Week 12 (Week 60, V9), and FU Week 24 (Week 72, V10).

    Measured: Up to Week 72

  4. Mean Change From Baseline in Blood Pressure up to Week 72

    Mean change from Baseline in diastolic blood pressure (DBP) and systolic blood pressure (SBP) was recorded at Baseline (Screening visit [Days -30 to -1]) and at various Visits (V): Week 2 (V2), Week 4 (V3), Week 12 (V4), Week 24 (V5), Week 36 (V6) and Week 48 (V7) and after treatment completion at follow-up (FU) Week 4 (Week 52, V8), FU Week 12 (Week 60, V9), and FU Week 24 (Week 72, V10).

    Measured: From Baseline (Days -30 to -1) to Week 72

  5. Mean Change From Baseline in Heart Rate up to Week 72

    Mean change from baseline in heart rate was recorded at Baseline (Screening visit [Days -30 to -1]), and at various Visits (V): Week 2 (V2), Week 4 (V3), Week 12 (V4), Week 24 (V5), Week 36 (V6) and Week 48 (V7), and after treatment completion at follow-up (FU) Week 4 (Week 52, V8), FU Week 12 (Week 60, V9), and FU Week 24 (Week 72, V10).

    Measured: From Baseline (Days -30 to -1) to Week 72

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing peginterferon alfa-2a [Pegasys] in people with Hepatitis C, Chronic, run by Hoffmann-La Roche at 5 sites in Russia.

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 4 inclusion and 5 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 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Russia. 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?

Yes. Results are posted in the registry (first posted 25 Jul 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Participants Achieving Sustained Virologic Response at 24 Weeks Following Treatment Completion (time frame: At Week 72). 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?
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 Jul 2016.
