Study Details

Study Description

Brief Summary

The purpose of this open label study is to characterise the absorption, metabolism, excretion, and mass balance of [14C]-IDV184001AN ([14C]-IDV184001) in healthy adult male participants.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

The study is designed as an open label, single-dose study in healthy adult participants for the following reasons:

  • Oral administration of IDV184001AN has demonstrated linear PK and thus [14C]IDV184001AN will be given as a single dose.

  • A comparator is not necessary for the evaluation of the objectives.

  • Blinding of the study treatment is not required as there is no comparator.

  • Conducting the study in healthy participants mitigates the potential confounding effects of the disease state and concomitant medications.
