Trial summary

This study will evaluate the drug telbivudine (LdT) for treatment of hepatitis B virus (HBV) in HIV infected patients. Patients will take telbivudine alone for 24 weeks, add anti-HIV drugs for 24 weeks, then stop taking telbivudine while continuing their anti-HIV drug regimen. Read more about this study

About this study

Official title: Multicenter, Pilot Study of Telbivudine (LdT) Anti-HBV Treatment Prior to the Initiation of Highly Active Antiretroviral Therapy Containing Lamivudine in Subjects Coinfected With HBV and HIV

This study will evaluate the drug telbivudine (LdT) for treatment of hepatitis B virus (HBV) in HIV infected patients. Patients will take telbivudine alone for 24 weeks, add anti-HIV drugs for 24 weeks, then stop taking telbivudine while continuing their anti-HIV drug regimen. To enroll in this study, patients must not be taking any anti-HIV drugs and cannot have taken more than 31 days of treatment with lamivudine (3TC), protease inhibitors (PIs), or nonnucleoside reverse transcriptase inhibitors (NNRTIs).

Read the detailed description

Studies indicate that 70% to 80% of HIV infected patients have or have had HBV infection and that 10% are HBV carriers. Lamivudine therapy for treatment of HBV in HIV infected patients has limited long-term efficacy due to the development of resistance mutations. Telbivudine is a thymidine analogue with excellent HBV inhibitory activity but no anti-HIV activity. The primary objective of this study is to evaluate the safety and anti-HBV activity of telbivudine alone and in combination with a lamivudine-based highly active antiretroviral therapy (HAART) regimen in patients coinfected with HBV and HIV.

Patients in this study will take telbivudine for 24 weeks. At Week 24, patients will add a HAART regimen containing lamivudine and efavirenz plus either didanosine or abacavir. Patients who are unable to add a HAART regimen at Week 24 due to lab abnormalities or other contraindications will be allowed to delay the initiation of HAART until Week 30. Patients may initiate HAART prior to Week 24 if deemed medically necessary by the primary HIV care provider. Patients will take both telbivudine and HAART for 24 weeks. At Week 48, patients will discontinue telbivudine and continue on the HAART regimen alone for an additional 12 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing Telbivudine, Lamivudine and Efavirenz in people with HIV Infections and Hepatitis B, run by National Institute of Allergy and Infectious Diseases (NIAID).

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 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: withdrawn, as of the sponsor's last update on 1 Nov 2021. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

HBV viral loads (time frame: At Study entry, Week 24 and Week 48). 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 NCT00051090, which also lists 4 linked publications.

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 1 Nov 2021.
