About this study

Official title: CIDRZ 1201 - Optimizing Clinical Outcomes in HIV-Infected Adults & Children Using Xpert MTB/RIF in Zambia

This is a study to evaluate Xpert MTB/RIF as the first-line TB diagnostic test in HIV-infected adults and pediatric patients as a means to obtain faster, more accurate TB diagnosis.

Read the detailed description

This study will evaluate Xpert Mycobacterium Tuberculosis/Rifampicin (MTB/RIF) as the first-line Tuberculosis (TB) diagnostic test in Human Immunodeficiency Virus (HIV)-infected adults and pediatric patients in peri-urban settings and determine its impact on accurate case detection and treatment initiation in these settings. In addition, the Determine TB-Lipoarabinomannan (LAM) Ag® will be used to model added diagnostic value when used alone or in combination with Xpert MTB/RIF, within the TB diagnostic algorithm for HIV infected patients in Zambia.

A quasi-experimental "before-after" study design will be used at two similar peri-urban district hospitals. Each site will initially implement the Standard of Care (SOC) phase, in which a prospective cohort of HIV-infected adult and pediatric TB suspects will be screened for TB according to the current standard of care in Zambian HIV care clinics. This will be followed by a 4-week "intervention wash-out" period to allow completion of the diagnostic work-up of all patients recruited during the last month of the SOC phase.

The second phase (Xpert MTB/RIF phase) will start immediately following the "intervention wash-out" period. In this phase, a second cohort of HIV-infected adult and pediatric TB suspects will be screened for TB using the Xpert MTB/RIF algorithm. Each phase will last approximately 6 months, or until the target sample size for adults is reached. Mycobacterial culture will be performed during the study to confirm TB diagnosis and determine whether appropriate treatment was given. "Appropriate treatment" means the patient was initiated on ATT within 4 weeks of screening initiation for culture-positive patients or a correct diagnosis of not having TB in culture-negative patients. Culture results will be released from the CIDRZ Lab for patient care as soon as results are available.

During both study phases participants will be asked to submit a urine sample for testing with the Determine TB-LAM Ag® assay. Urine specimens will be collected at the study site and all procedures will be carried out at the CIDRZ Central Laboratory in Lusaka using standard laboratory protocols and quality assurance procedures. Since Determine TB-LAM Ag® has not yet been endorsed by the World Health Organization (WHO) nor approved by the Zambian Ministry of Health for TB diagnosis, results from the Determine TB-LAM Ag® assay will not be used for patient care.

What is being measured

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

  1. Proportions of adult and paediatric patients receiving appropriate TB treatment in each study phase

    proportions of adult and pediatric patients receiving appropriate TB treatment in each study phase, using mycobacterial culture as the reference standard, and the feasibility and cost effectiveness of Xpert MTB/RIF in this setting

    Measured: within 4 weeks of initiation

Secondary outcomes (1)
  1. Clinical outcomes of subjects screened using the Xpert MTB/RIF algorithm compared to existing standard of care.

    Clinical outcomes to be compared include (but are not limited to):

    ART treatment start date CD4 response TB treatment outcomes at 6 months post-diagnosis Mortality Co-morbidities Other Opportunistic Infections Characteristics of TB patients who initially test Xpert negative (Xpert- /Culture + patients)

    Measured: 3 and 6 months post TB-screening

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 6 inclusion and 2 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 3 Aug 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 Zambia. 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.

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?

Proportions of adult and paediatric patients receiving appropriate TB treatment in each study phase (time frame: within 4 weeks of initiation). 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 NCT02043080, which also lists 38 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 3 Aug 2017.
