About this study

Official title: Impact of a Package of Intensive Smoking-cessation Interventions Versus Smoking-cessation Advice on Outcomes in Smear-positive Patients With Pulmonary Tuberculosis; a Randomised Controlled Trial (STB_RCT).

The aim of the study is to determine the impact of a package of smoking-cessation interventions on a composite measure of Tuberculosis (TB) treatment-related outcomes.

Given the lack of objective clinical data/evidence about the impact of smoking-cessation on TB-related outcomes, yet subjective expert opinion that smoking cessation is highly likely to be beneficial particularly in patients with TB, this study proposes to determine the impact of an intensive package of smoking-cessation interventions aimed to promote smoking-cessation (counseling plus nicotine replacement therapy, NRT), on patient response to anti-tuberculosis therapy. This is to be compared with the structured counselling for smoking-cessation that is recommended to be routinely provided by health care workers to all patients who are smokers. If the results prove that such a smoking-cessation PI indeed improves outcomes in TB patients, such information would strongly motivate for the institution of more intensive smoking-cessation interventions in TB clinics than is currently being employed for TB patients

Read the detailed description

No clinical trials have been done to determine if the cessation of smoking has any influence on outcome in tuberculosis patients. In particular, if smoking cessation leads to a higher rate of sputum culture-conversion at 2 months, TB transmission rates should be reduced. Such targeted smoking-cessation intervention may be more successful than general public education strategies in reducing the spread of TB in high-incidence countries Tuberculosis (TB) . The WHO has estimated that approximately a third of the world's population is infected with Mycobacterium tuberculosis, and approximately 2 million die from TB every year. Tobacco smoking, which is the single most preventable cause of death in the world today, appears to be an important risk factor for TB disease and mortality, especially in countries such as India. The smoking-TB association has major public health implications because in many of the developing countries where there is a high prevalence of TB, smoking is also a common practice. Smoking is widespread, with approximately a third of the global population aged 15 years or above being smokers, but has reached epidemic proportions in countries such as India, China and Russia. For example, in India more than half of the rural male population is estimated to smoke and India accounts for 1.85 million TB cases each year. Therefore in India, as for other developing countries, the co-existence of a high TB and smoking burden is a major health concern, and further underscores the importance of promoting smoking cessation to the general public. In India, studies have shown a strong association between tobacco and TB mortality. An estimated third of male TB deaths in India may be due to smoking. However, there is concern that many of the published studies did not adequately control for bias and confounding (that may have caused spurious associations).

What is being measured

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

  1. 1. Change in TB Score at second month and sixth month

    Composite score for objective and subjective improvement measured at baseline, second month and sixth month

    Measured: Measured at baseline, second month and sixth month.

  2. Sputum culture conversion

    Sputum culture conversion at second month using solid/liquid culture technique

    Measured: Measured at baseline and second month

Secondary outcomes (6)
  1. Sputum smear conversion

    Protocol was amended to access sputum conversion weekly up to second month

    Measured: Measured at baseline, second week, fourth week, second month and sixth months

  2. Mortality at sixth month

    To determine number of mortality at the end of follow-up

    Measured: Sixth month

  3. More than 10% weight gain at six months

    To determine rate of weight gain after completion of treatment

    Measured: Sixth month

  4. Proportion of subjects in each group that have quit smoking at second month

    To determine the rate of smoking cessation in the cohort

    Measured: Sixth month

  5. Treatment completion

    Measured: Six months for new cases and eight months for re-treatment cases following regimen 2

  6. Cure, failure and default rate

    To determine cure, failure and default rate in the cohort

    Measured: At sixth month

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing nicotine replacement therapy in people with Tuberculosis, run by All India Institute of Medical Sciences at 1 site in India.

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 2 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 13 Oct 2017. 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 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. 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?

1. Change in TB Score at second month and sixth month (time frame: Measured at baseline, second month and sixth month.). The study lists 2 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 NCT01517022, 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 13 Oct 2017.
