What this trial studies

This observational study investigates the pharmacokinetics of pretomanid in patients diagnosed with tuberculosis. Participants will undergo dynamic 18F-pretomanid PET/CT imaging after receiving an intravenous injection of the radiotracer. The goal is to noninvasively determine how pretomanid distributes and is processed in the body, providing insights into its effectiveness and behavior in treating tuberculosis.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed tuberculosis or high suspicion of active tuberculosis.

Not a fit: Patients without tuberculosis or those who are not willing to comply with the study protocol may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of pretomanid's pharmacokinetics, potentially leading to improved treatment strategies for tuberculosis.

How similar studies have performed: While this approach is innovative, similar studies have shown promise in understanding drug behavior in infectious diseases.
