About this study

Official title: Phase III Clinical Study of Efficacy and Safety of Mycobacterium Vaccae to Prevent Tuberculosis in High Risk Groups of Tuberculosis Infection

Mycobacterium Vaccae for Injection (Trade Name "Vaccae") is a kind of bio-products developed by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd.,and got "The New Drug Certificate "in 1999. Vaccae has been approved for adjuvant therapy of tuberculosis(TB), and is also the only recommended drug in TB immunotherapy by WHO. It was approved for production and sale by Anhui Zhifei Longcom Biopharmaceutical Co.,Ltd. in 2001, and got favourable comment in therapy of tuberculosis.

The purpose of this study is to add new indications for Vaccae, mainly to prevent Tuberculosis for high risk groups of Tuberculosis Infection . In December 2012, China Food and Drug Administration approved of the plan "Phase III Clinical Study of Efficacy and Safety of Mycobacterium Vaccae to Prevent Tuberculosis in high risk groups of Tuberculosis Infection". In the test, 10,000 cases whose skin tests of PPD are strongly positive are enrolled. Using random, double-blind, and placebo-controlled methods, the study is carried out to evaluate the efficacy and safety of Vaccae in preventing Tuberculosis. Meanwhile, in this test, TB incidence and degree of pathological changes of experimental group are lower than that of control group, and no drug-related SAEs are reported in treatment groups.

Read the detailed description

The Main Purpose of the Study:

  • Evaluation of efficacy of Vaccae to prevent Tuberculosis in high risk groups of Tuberculosis Infection.

The Secondary Purpose of the Study:

  • Evaluation of Lesion Degree ( Bacteriology Indicators, Cavity) of patients and its relationship with Skin Test results of TB-PPD after Injection of Vaccae into the high risk groups.
  • Evaluation of Changes in Humoral Immunity and Cellular Immunologic Response Before and After Injection of Vaccae

Test Hypothesis:

In the test, TB incidence and degree of pathological changes of experimental group are lower than that of control group, and no drug-related SAEs are reported in treatment groups

Blinding and Random:

Using random, double-blind, and placebo-controlled methods, evaluation of the efficacy and safety of Vaccae.

Using block randomization method, a random sequence was generated by the statistics personnel in Fourth Military Medical University Clinical Evaluation Center using SAS9.1.3 statistical software

The Unblinding includes the first time of Unblinding and the second time of Unblinding. The first time of Unblinding only distinguish groups , and the second time of Unblinding will uncover the final Blind Codes.

The Blind Codes of the design produce at one time, and unblinding will be carried out respectively at the first year and the second year after the beginning of the experiment.

What is being measured

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

  1. The whole TB incidence after injection of Vaccae

    Medium-term: one year after the last group of subjects enrolled or after observation of 38 cases of the disease, Terminal Stage: two years after the last group of subjects enrolled or after observation of 76 cases of the disease

    Measured: Terminal Stage: two years after the last group of subjects enrolled

Secondary outcomes (3)
  1. Lesion degree (Bacteriology indicators, cavity) of patients

    Medium-term: one year after the last group of subjects enrolled or after observation of 38 cases of the disease, Terminal Stage: two years after the last group of subjects enrolled or after observation of 76 cases of the disease

    Measured: two years after the last group of subjects enrolled or after observation of 76 cases of the disease

  2. Systemic and local reactions and adverse events

    within 30 days after last dosing

    Measured: within 30 days after last dosing

  3. The relation between skin test results and paroxysm of TB-PPD

    Medium-term: one year after the last group of subjects enrolled or after observation of 38 cases of the disease, Terminal Stage: two years after the last group of subjects enrolled or after observation of 76 cases of the disease

    Measured: Terminal Stage: two years after the last group of subjects enrolled or after observation of 76 cases of the disease

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Vaccae in people with Tuberculosis, run by Anhui Zhifei Longcom Biologic Pharmacy Co., Ltd. at 4 sites 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 8 inclusion and 16 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 1 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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. 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.

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?

The whole TB incidence after injection of Vaccae (time frame: Terminal Stage: two years after the last group of subjects enrolled). 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 NCT01979900, 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 1 Jun 2018.
