Clinical Trial 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.

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.

21. Has received radiolabelled substances or has been exposed to radiation sources over the past 12 months or is likely to receive radiation exposure or radioisotopes within the next 12 months such that participation in this study would increase their total exposure beyond the recommended levels considered safe (ie, weighted annual limit recommended by the FDA 21CFR361 of 3000 mrem; FDA 2023).

22. Site staff and/or participants who have a financial interest in, or an immediate family member of either the site staff and/or Indivior employees, directly involved in the study.
