Brief Summary

The objective of the study is to evaluate the bioavailability of CHF6001 after inhaled administration, to characterize the mass balance and route of elimination of CHF6001 along with its relevant metabolites, in healthy male subjects.

Detailed Description

This clinical trial is a single centre Phase I study, with a single dose, non-randomized, open-label, uncontrolled design. A total of 8 healthy male subjects were included in the study.

The aim was to assess the absolute bioavailability, the mass balance, and routes of elimination of CHF6001 (Tanimilast) in healthy male subjects, using [14^C]-radiolabelled drug substance, administered as an intravenous (iv) infusion concomitantly with an inhaled (inh) non-radiolabelled dose of CHF6001.

Standard safety assessments were conducted during the study, including safety blood and urine laboratory tests, vital signs, physical examinations, ECGs, and assessment of any adverse events (AE). Blood, urine, and feces samples were collected for pharmacokinetic (PK) analyses.
