Summary

This protocol aims to evaluate the feasibility and benefit of Intrapulmonary Percussive Ventilation (IPV) to improve deposition of inhaled radiolabelled aerosols in fibrotic lung regions of patients with Idiopathic Pulmonary Fibrosis (IPF).

Phase 1 of the protocol aims to identify the highest IPV pressure that is tolerated by individual patients. Secondary endpoints explore safety of IPV in IPF patients.

Phase 2 of the protocol is a crossover randomized trial where patients will inhale 99mTc-labelled DiethyleneTriamine PentaAcetate (DTPA) aerosols with or without IPV. Aerosol deposition in HRCT-defined fibrotic regions of interest (ROI) is described by Single Photon Emission Computed Tomography (SPECT).

Conditions

Interventions

DEVICE

intrapulmonary percussive ventilation

Intrapulmonary percussive ventilation is a non invasive ventilation technique where small boli or air are delivered, at adjustable frequency and pressure, to the upper airways though a mouthpiece. IPV is currently used in the clinic to aid with airway clearance in neuromuscular and airway diseases.

RADIATION

delivery of 99mTc-DTPA aerosol

A 99mTc-DTPA aerosol (500 MBq+/-20%, 3 ml volume) is generated with a jet nebuliser (MMAD 4 µm). The aerosol is inhaled by the study subject and lung deposition is imaged by SPECT
