Trial summary

Tuberculosis (TB) is a leading cause of death in HIV-infected individuals. There are insufficient data correlating concentrations of anti-TB drugs with treatment response. We hypothesize that sub-therapeutic concentrations of anti-TB drugs are associated with inadequate TB treatment response to Mycobacterium… Read more about this study

About this study

Official title: Evaluation of the Pharmacokinetics of Antituberculosis Drugs and Tuberculosis Treatment Outcomes in HIV-tuberculosis Co-infected Ugandan Adults

Tuberculosis (TB) is a leading cause of death in HIV-infected individuals. There are insufficient data correlating concentrations of anti-TB drugs with treatment response. We hypothesize that sub-therapeutic concentrations of anti-TB drugs are associated with inadequate TB treatment response to Mycobacterium tuberculosis.

Read the detailed description

During the study periodic monitoring will be conducted to ensure that the protocol and Good Clinical Practices (GCPs) are being followed.The monitors may review source documents to confirm that the data recorded on CRFs is accurate. The study site may be subject to review by the Institutional Review Board (IRB) and/or appropriate regulatory authorities.

A CRF will be completed for each included subject and will be signed by the investigator or by an authorized staff member to attest that the data is true. Any corrections to entries made in the CRFs, source documents must be dated, initialed and explained (if necessary) and should not obscure the original entry. Qualit assurance will as also be performed regularly on the CRFs.

The primary end point will be analyzed using Time to event (cure, death, relapse etc)analysis and failure rates and hazard ratios will be calculated accordig to categorical drug concentrations with proposed cutt offs.

Secondary end points will be analysed using time to event for occurence of toxicities which will also be corelated to the drug concentrations.

Being tested
Rifampicin, Isoniazid, Ethambutol, Pyrazinamide

What is being measured

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

  1. clinical outcome

    To investigate the association between serum concentrations of antituberculosis drugs and tuberculosis treatment response in HIV-TB-co-infected individuals.

    Measured: At the end of treatment (6 months after enrolmet)

Secondary outcomes (4)
  1. Cmax

    To investigate the steady-state pharmacokinetic parameters of anti-TB drugs at different time-points over the course of TB-treatment

    Measured: At 2 weeks, 8 weeks and 24 weeks after anti-tuberculosis drug initiation

  2. Number of adverse events

    To assess the safety and tolerability of anti-TB drugs based on the WHO guidelines

    Measured: 2 weeks, 8 weeks and 24 weeks after anti-tuberculosis drug initiation

  3. ART trough levels

    To correlate the effect of anti-TB drugs on plasma concentrations of efavirenz or protease inhibitors and vice versa.

    Measured: At 2 weeks, 8 weeks and 24 weeks after anti-tuberculosis drug initiation

  4. Isoniazid Cmax

    To evaluate the effect of acetylator geno-and phenotype (NAT-2 gene) on isoniazid plasma concentrations and toxicity

    Measured: At 2 weeks, 8 weeks and 24 weeks

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 5 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 13 Apr 2015. 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 Uganda. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Andrew Kambugu, MMED (+256-414-307000 ext. 227, akambugu@idi.co.ug), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

clinical outcome (time frame: At the end of treatment (6 months after enrolmet)). 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 NCT01782950, 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 13 Apr 2015.
