About this study
Official title: A Randomized, Double-Blind Trial of Telbivudine (LdT) Versus Lamivudine in Adults With Decompensated Chronic Hepatitis B and Evidence of Cirrhosis.
This trial is being done to see if the investigational drug, LdT (Telbivudine), is safe and effective in the treatment of hepatitis B infection. In addition to this, we will be looking at the comparison of the effects (good and bad) of LdT and lamivudine.
Read the detailed description
This study is a randomized, double-blinded trial looking at the drug Telbivudine (LdT) and comparing it to the drug lamivudine in patients with chronic hepatitis B and evidence of Cirrhosis.
Interested participants will first be seen for a screening visit, to determine eligibility for the study. Participants will have a medical history taken along with a physical exam and a blood draw. Prior to receiving the study drug, participants may be required to have a liver biopsy. If one was done in the past 5 years, it may be possible to use the results of the previous biopsy. If participants are unable to have a liver biopsy due to medical reasons, an ultrasound, CT, or MRI scan may be done instead. If an imaging study has been done in the past two years, it may be possible to use the results from this test.
All eligible participants will be put into one of two groups by chance (as in the flip of a coin). One group will receive 600 mg of LdT (3 tablets) plus a lamivudine placebo capsule (1 sugar pill) daily. While the other group will be receiving 100 mg of lamivudine (1 capsule) plus 3 LdT tablets (3 sugar pills) daily. Participants will take the study drug daily for a total of 104 weeks (2 years).
Participants will return for clinic visits at weeks 2, 4, 8, 12, 16, 24, 32, 40, 48, 52, 60, 68, 76, 84, 92, 100, and 104. Participant's vital signs (temperature, pulse, weight) and blood samples will be collected at each visit.
If after one year of being on the drug, there is no hepatitis b found in your blood, you may be stopped from the study drug. Participants will continue to be required to return to the clinic for study visits so information can be continued to be collected and for your condition to be monitored. If future blood tests show that the hepatitis B virus returned, participants will be told to restart their study drug.
At the end of the 104 weeks or if the treatment was stopped early for any reason except a liver transplant, or if additional treatment was not chosen for hepatitis B, participants will be asked to return to the clinic once every four weeks for 4 months. For each return visit to the clinic, vital signs and blood samples will be collected and recorded. A physical exam will be at the last follow-up visit.
If the study was stopped due to a liver transplant, participants will be asked to return for clinic visits at 4 and 16 weeks after surgery. At these visits, no procedures will be done, but a review of the participant's medical record.
Participants will be involved for 2 years and 4 months.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing LdT (Telbivudine) and lamivudine in people with Hepatitis B and Cirrhosis, run by Mayo Clinic 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?
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 23 Mar 2011. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
A composite endpoint called "clinical response" which is defined as HBV DNA <10 4 copies/ml and normal ALT and improvement, or stabilization in CTP score.. The study lists 5 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 23 Mar 2011.
