About this study

Official title: A Single-Arm Study Evaluating the Efficay and Safety of Tenofovir DF,Lamivudine and Efavirenz in Adults With HIV/HBV Coinfection

This is a Phase 4 single-arm, post-marketing clinical trial evaluating the efficacy and safety of tenofovir disoproxil fumarate, lamivudine and efavirenz in adults with human immunodeficiency virus-1 and hepatitis B virus coinfection.

Read the detailed description

HIV/HBV co-infections are frequently observed due to shared routes of transmission. TDF and 3TC are nucleotide analogues that can inhibit both HIV and HBV DNA polymerases. There is higher risk to cause drug resistance in treating HBV or HIV infection with 3TC or TDF monotherapy than combination trerapy. Combination tharapy could decreases drug resistance. China's HIV epidemic remains one of low prevalence overall, but with pockets of high infection among specific sub-populations and in some localities. China has a very high endemicity for hepatitis B too. A substantial proportion of HIV-infected individuals are co-infected with HBV. TDF + 3TC + EFV will be a common regimen for HIV/HBV co-infected Chinese individuals.

The purpose of this study of this study is to determine whether TDF will be safe for patients with HIV and HBV co-infection and the combination of TDF+3TC+EFV will suppress HIV and HBV viral load below LDL at week 48 of treatment in patients with HIV and HBV co-infeciton.This study will enroll 100 adult subjects and follow these patients for 48 weekes.There will be one enrollment visit(baseline) and visits at 2,4,8,12,24,36,48 weeks after initiation of the study regimen.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Regimen:TDF+3TC+EFV in people with Hiv, run by National Center for AIDS/STD Control and Prevention, China CDC at 1 site in China.

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 4 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 28 Jun 2013. 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 China. 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?

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?

Proportion of patients with HIV RNA below LDL and HBV DNA below 2.3log10 copies/ml at week 48 (time frame: one year). 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 NCT01751555, which also lists 2 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 28 Jun 2013.
