Biodistribution and Pharmacokinetics of Pretomanid in Tuberculosis Patients Using 18F-Pretomanid PET

Recruiting

• Conditions: Tuberculosis
• Interventions: Combination Product: 18F-Pretomanid PET/CT

• Registration Number: NCT05609552
• Lead Sponsor: Johns Hopkins University

Brief Summary

This is an observational study that will examine the pretomanid pharmacokinetics (PK) in tuberculosis (TB) patients. Dynamic 18F-pretomanid PET/CT will be performed after intravenous injection of 18F-pretomanid to determine multi-compartment, noninvasive determination of pretomanid PK in TB patients.
