A Study to Investigate the Safety, Tolerability and Pharmacokinetics of Inhaled CHF10073 After Single and Multiple Doses in Healthy Volunteers

Phase 1

Recruiting

• Conditions: Pulmonary Fibrosis
• Interventions: Drug: CHF10073 (Part 1 - SAD); Drug: Placebo (Part 1 - SAD); Drug: CHF10073 (Part 2 - MAD); Drug: Placebo (Part 2 - MAD); Drug: CHF10073 (Part 3)

• Registration Number: NCT06746064
• Lead Sponsor: Chiesi Farmaceutici S.p.A.

Brief Summary

The objective of this study is to assess the safety and tolerability of single ascending doses of inhaled CHF10073 (Part 1 of the study) and multiple ascending doses of CHF10073 (Part 2 of the study). The study will also evaluate the PK profile of study drug in plasma and urine after single and repeated administrations of CHF10073.

In addition, this study will also investigate the metabolites profile of CHF10073 in plasma, urine and faeces (Part 2 of the study) and the PK profile of CHF10073 in the lungs after bronchoalveolar lavage (BAL) (Part 3 of the study).
