Exploratory Study of Inhaled Afatinib Dimaleate PK Profile

Plain-language summary

This is a pilot Phase I open-label randomized single-dose two-period crossover study (in the EDDIS project) evaluating the bioequivalence, pharmacokinetics (PK), safety, and tolerability of inhaled afatinib dimaleate compared with the reference oral afatinib dimaleate in healthy volunteer smokers. The study will enroll healthy adult volunteers smoker to assess the systemic exposure and lung deposition of inhaled afatinib dimaleate. Participants will receive both the test inhaled formulation and the reference oral formulation in separate periods with delayed phase between treatments. Key endpoints include maximum plasma concentration (Cmax), area under the concentration-time curve (AUC), and lung deposition assessed via bronchoalveolar lavage (BAL), frequency of occurrence of side effects and cases of toxicity during the studies
