Trial summary

Patients with primary biliary cirrhosis (PBC) develop progressive liver disease and often require liver transplantation. The cause of disease is unknown. It is thought to occur as a result of an infection in subjects that are more susceptible to disease than others. Read more about this study

About this study

Official title: Randomized Controlled Pilot Study of Highly Active Anti-Retroviral Therapy for Patients With Primary Biliary Cirrhosis

Patients with primary biliary cirrhosis (PBC) develop progressive liver disease and often require liver transplantation. The cause of disease is unknown. It is thought to occur as a result of an infection in subjects that are more susceptible to disease than others. The investigators found evidence of retrovirus infection in patients with primary biliary cirrhosis. The investigators found that most patients with PBC have evidence of viral infection. Since then the investigators have conducted clinical studies using anti-viral therapy. The investigators found that PBC patients treated with combination anti-retrovirus therapy experienced significant reversal of the disease process. However, the changes were not substantial and the investigators are now looking for better antiviral regimens. Now the investigators have found a mouse model with a similar virus infection that develops a similar biliary disease. Importantly, the investigators found that antiviral therapy blocks the development of the disease in this mouse. The investigators have used this model to find safer and more effective antiviral treatments for patients with PBC. The investigators have now found out that a combination of highly active antiretroviral therapy with Truvada and Kaletra stops disease in the mouse and plan to use this combination to see if it works in patients with PBC.

What is being measured

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

  1. Reduction of ALP to 1.67x ULN

    Measured: The outcomes will be measured are from 12 to 24 weeks at the end of the study

  2. normalization of bilirubin.

    Measured: The outcomes will be measured are from 12 to 24 weeks at the end of the study

Secondary outcomes (5)
  1. Reduction of human betaretrovirus.

    Measured: The outcomes will be measured are from 12 to 24 weeks in RCT; and 6 monthly to 2 years for the extension study

  2. Symptoms with changes in PBC-40

    Measured: The outcomes will be measured are from 12 to 24 weeks in RCT; and 6 monthly to 2 years for the extension study

  3. Changes in AMA and immunoglobulin levels

    Measured: The outcomes will be measured are from 12 to 24 weeks in RCT; and 6 monthly to 2 years for the extension study

  4. Biochemistry: GGT, AST and ALT

    Measured: The outcomes will be measured are from 12 to 24 weeks in RCT; and 6 monthly to 2 years for the extension study

  5. Histology in extension study

    Measured: The outcomes will be measured are from 12 to 24 weeks in RCT; and 6 monthly to 2 years for the extension study

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted7 Jun 2012 (estimated)
  2. Study startJun 2012
  3. Primary completionJul 2015
  4. Study completionAug 2015

Why it stopped: Protracted gastrointestinal symptoms were experienced by most patients who were subsequently found to be in the treatment arm on LPV/r. This observation resulted in cessation of enrolment and a decision not to continue the RCT

Questions about this trial

What is this clinical trial studying?

A study testing TDF/FTC/LPV/r in people with Primary Biliary Cirrhosis, run by University of Alberta at 1 site in Canada.

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 5 inclusion and 10 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 21 Nov 2024. 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 Canada. 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.

Are results available for this study?

The study was stopped early (reason given: Protracted gastrointestinal symptoms were experienced by most patients who were subsequently found to be in the treatment arm on LPV/r. This observation resulted in cessation of enrolment and a decision not to continue the RCT). 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?

Reduction of ALP to 1.67x ULN (time frame: The outcomes will be measured are from 12 to 24 weeks at the end of the study). The study lists 2 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 NCT01614405, 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 21 Nov 2024.
