NCT05283967

Brief Summary

The purpose of the study is to generate receiver-operating-characteristic (ROC) curves for urine colorimetry to identify tuberculosis (TB) patients (children and adults) with low drug anti-TB drug exposures, which will define the diagnostic accuracy. The central hypothesis is that urine colorimetry will successfully identify patients with low anti-TB serum drug levels, and do so with diagnostic characteristics similar to other widely used tests in TB management.

    Day 1

  • Urine pyrazinamide Cmax

    Urine peak concentration (Cmax) of pyrazinamide as determined by urine colorimetry

    Day 1

  • Urine pyrazinamide AUC

    Day 1

Study Arms (2)

Adults and children, U.S.

A prospective, observational study of the pharmacokinetics of first-line anti-TB drugs (isoniazid, rifampin, and pyrazinamide) among TB patients (i.e. patients with active TB disease) will be conducted.

Diagnostic Test: urine colorimetric assay

Tanzanian children

A prospective, observational study of the pharmacokinetics of first-line anti-TB drugs (isoniazid, rifampin, and pyrazinamide) among TB patients (i.e. patients with active TB disease) will be conducted.

Diagnostic Test: urine colorimetric assay

Interventions

Colorimetric assays will be performed for urine drug concentrations of rifampin, isoniazid and pyrazinamide from urine collected throughout one dosing interval. Assay results will experimental only and not used to change patient care.

Adults and children, U.S.Tanzanian children

Eligibility Criteria

Age4 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Study personnel will review the daily clinic rosters at each enrollment site to identify patients with TB who have initiated or are planning to initiate first-line anti-TB therapy with a regimen that includes isoniazid, rifampin, and pyrazinamide.

You may qualify if:

  • Patients of male and female sex meeting all of these criteria:
  • Those 4 years and older;
  • Diagnosed with active TB and initiation of combination anti-TB therapy with isoniazid, rifampin, and pyrazinamide, with or without DM;
  • Able to provide informed consent and assent for those 7-17 years old.

You may not qualify if:

  • Anuric (i.e. not capable of producing urine due to chronic renal disease);
  • Pregnancy or breastfeeding;
  • Prisoners
