About this study

Official title: Efficacy and Safety Study of Immunomodulator (Mycobacterium w) as an Adjunct Therapy in Category-II Pulmonary Tuberculosis Along With Assessment of Immunological Parameters

The purpose of the study is to study the efficacy and safety of Mycobacterium in treating patients with lung tuberculosis . Mycobacterium is a strain of bacterium which is used as a vaccine and an adjuvant drug against leprosy. This agent has also been found to be effective in the treatment of lung tuberculosis in a limited number of patients.

The researchers are conducting this study in the World Health Organization (WHO) category-II of lung tuberculosis patients to see the efficacy and also to see any change in immunological parameters.

Read the detailed description

Mycobacterium w is a recently introduced immunomodulator, which has been found to be useful in rapid killing of Mycobacterium leprae. It improves the clearance of Mycobacterium leprae from the body and is thereby useful in reducing the duration of therapy significantly for multibacillary leprosy. Mycobacterium w shares an antigen with both Mycobacterium leprae as well as Mycobacterium tuberculosis. Mycobacterium w is also found to be useful in the prevention of tuberculosis in experimental animals.

Previous studies on the efficacy of Mycobacterium w as an immunomodulator in pulmonary tuberculosis patients have shown higher sputum conversion rates in patients given Mycobacterium w as an adjuvant therapy along with standard anti-tuberculosis treatment. It has faster and remarkable sputum converting capacity. Similar studies conducted in pulmonary TB category -II [re-treatment as per Revised National Tuberculosis Control Programme (RNTCP), Govt. of India] patients have shown improved cure rates.

Mycobacterium w is commercially available under the brand name of "Immuvac" injection in 0.5 ml multi dose vials approved for use as immunomodulator against Mycobacterium leprae in patients with leprosy. Each vial has 0.5 x 10^9 heat-killed bacilli in a buffered solution. It is manufactured by Cadila Pharmaceuticals Ltd.; Ahmedabad, Gujarat-382 210, India. In this clinical trial one dose consists of 0.1 ml given as an intradermal injection, which contains 10^9 bacilli. A total of 6 doses are given during the Intensive Phase (as per RNTCP, Govt. of India) of treatment. Two injections on both upper arms on day-0 and subsequently one injection on days 14, 28, 42 and 56. No injections are given during the Continuation Phase (as per RNTCP, Govt. of India) of treatment.

As of now, it is not commercially available for use in TB patients as an immunomodulator. Therefore, the investigators are investigating Mycobacterium w (Mw) for its efficacy in TB patients in a "double-blind placebo-controlled randomized clinical control trial" fashion. We are conducting this trial in Category-II pulmonary TB patients (as per RNTCP, Govt. of India), and are assessing the outcome in the form of clinical improvement, sputum conversion and immunological parameters. This is a multi-centric trial sponsored by the Department of Biotechnology, Ministry of Science and Technology, Govt. of India and Cadila Pharmaceuticals Ltd., India.

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intra-dermal administration of Mycobacterium wBiological

    Also called Immuvac

    Mw Vaccine is given as oral suspension. Total 6 doses are given 0.2 ml at baseline and then 0.1 ml after interval of 2 weeks upto 8 weeks

Study groups in NCT00265226
Study groupRoleWhat they receive
1ExperimentalIn one arm the patient will receive intradermal Mycobacterium W Vaccine along with Category II ATT according to RNTCP guidelines

2Placebo comparatorIn this Arm patient will receive Placebo along with Category II ATT drugs according to RNTCP guidelines
Receives: Biological: Intra-dermal administration of Mycobacterium w

What is being measured

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

  1. The time of sputum conversion as well as the early sputum conversion between the 2 groups will be evaluated.

    Measured: from baseline (visit 2)

  2. The cure rate will be evaluated as the primary parameter of efficacy.

    Measured: 8-9 months

  3. The relapse in patients of category II tuberculosis will be compared in both the groups.

    Measured: at an interval of 6, 12, 18 and 24 months after the completion of the therapy

  4. Recording of any clinical adverse reactions at anytime during the study for assessment of safety

    Measured: 2-8 weeks

Secondary outcomes (1)
  1. An additional secondary efficacy endpoint is the patient's and physician's global assessment of the clinical cure.

    Measured: 8-9 months

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 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 6 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in India. 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 time of sputum conversion as well as the early sputum conversion between the 2 groups will be evaluated. (time frame: from baseline (visit 2)). The study lists 4 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 NCT00265226, which also lists 9 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 6 Jan 2014.
