About this study

Official title: Phase IV; Different Extend Treatment Duration (6 Months vs 12 Months After Chemotherapy) to Prevent HBV Relapse With Tenofovir for Prophylaxis in Patients With Malignant Tumor Combined With HBV Carrier Receiving Chemotherapy

To evaluate the effectiveness and safety of tenofovir for different treatment duration in preventing HBV relapse in patients with malignancies after receiving chemotherapy and off-treatment of chemotherapy.

Read the detailed description

This study aims to evaluate the effectiveness and safety of tenofovir in preventing HBV relapse in HBV carriers with malignant tumor following chemotherapy. Approximately 100 patients who are planned to receive chemotherapy for malignant tumor will be invited to participate in this trail. A 1 or less 1-week tenofovir prophylaxis treatment should be administered by all subjects prior to the chemotherapy and eligible subjects will be randomly assigned to extend 24-week prophylaxis group A or 48-week prophylaxis group B in a 1:1 ratio at the end of the chemotherapy. The subjects could be stopped or withdrawn from this study earlier if HBV relapses or need to receive another course of chemotherapy respectively. The relapse episode will be followed until 24 weeks after the end of prophylaxis therapy. Data collection will take place at screening, every cyclic visit of chemotherapy, at the end of chemotherapy, and the following prophylaxis period, then every 4 weeks during the follow-up period. Patients in both groups will be treated with tenofovir or other antiviral agent according to investigator judgement when HBV relapse after discontinuation of tenofovir therapy.

What is being measured

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

  1. To compare the HBV relapse rate during the follow-up period in HBV carriers with malignant tumor receiving tenofovir for 24 and 48 weeks after the end of chemotherapy.

    To compare the HBV relapse rate during the follow-up period in HBV carriers with malignant tumor receiving tenofovir for 24 and 48 weeks after the end of chemotherapy.

    • HBV relapse is defined as: acute liver flare, i.e. ALT ≥ 2 x ULN and HBV DNA > 2000 IU/mL.

    Measured: 24 to 48 weeks

Secondary outcomes (1)
  1. To estimate the efficacy of TDF during chemotherapy with after chemotherapy and post-chemotherapy,as measure by the HBV reactivation, clinical relapse and adverse events in all patients.

    AST, ALT, Bil(T), Cr (eGFR or MDRD), phosphate, urine analysis, HBsAgQT and HBV DNA were measured at baseline, every 2 cycle of chemotherapy, the end of chemotherapy, the end of TDF and the end of complete follow-up (after the end of TDF for 6 months).

    Measured: The efficacy of TDF duration 24 wks versus 48 wks extended

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing TDF in people with Hepatitis B, Chronic and Tumor, run by Chang Gung Memorial Hospital at 1 site in Taiwan.

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 8 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 5 Feb 2020. 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 Taiwan. 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?

To compare the HBV relapse rate during the follow-up period in HBV carriers with malignant tumor receiving tenofovir for 24 and 48 weeks after the end of chemotherapy. (time frame: 24 to 48 weeks). 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 NCT02081469, 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 5 Feb 2020.
