Study population: The subjects are enrolled at the Fondazione IRCCS Policlinico San Matteo hospital in Pavia, at the SC of Pulmonology of the Foundation.

Brief summary: The PROMPTLY study is a proof-of-concept research project evaluating the efficacy of XHALIP, an innovative inhalable formulation of Imatinib, in treating pulmonary arterial hypertension (PAH) and post-inflammatory fibrosing lung diseases (LFD).

Main Objective To demonstrate the ability of XHALIP to improve the prognosis of PAH and LFD by reducing pulmonary fibrosis and vascular remodeling.

Key Research Questions Is XHALIP effectively absorbed by pathological lung cells? Does it have a beneficial biological effect on cell proliferation and extracellular matrix deposition? Study Plan Preclinical phase: In vitro tests on cells obtained from patients with PAH and LFD.

Absorption and distribution analysis: In vitro lung tissue models to assess drug penetration and effectiveness.

Biological activity assessment: Evaluating XHALIP's ability to inhibit epithelial-mesenchymal transition and cell proliferation.

Participants Patients aged ≥ 18 years diagnosed with PAH or LFD, either candidates for or recipients of lung transplantation.

Biological samples (bronchoalveolar lavage and explanted lung tissues). Methodology Confocal microscopy and flow cytometry to analyze absorption. RT-PCR and Western Blot to assess biological efficacy. Alveolo-capillary models to test drug release and distribution. The study aims to translate preclinical findings into a potential future clinical trial for the development of XHALIP as a novel inhalation-based therapeutic strategy for rare lung diseases.


Eligibility criteria: Inclusion Criteria:

* Patients aged ≥ 18 years diagnosed with fibrosing lung disease, obliterative bronchiolitis, or PAH, who are candidates for or have undergone lung transplantation.
* Obtaining informed consent for all patients enrolled prospectively and all those enrolled retrospectively at their first clinical occurrence at our center.

Exclusion Criteria:

* Suspected or confirmed diagnosis of pulmonary neoplastic disease.
