About this study

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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • intrapulmonary percussive ventilationDevice

    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.

  • delivery of 99mTc-DTPA aerosolRadiation

    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

Study groups in NCT05366387
Study groupRoleWhat they receive
Aerosol delivery without intrapulmonary percussive ventilation (Control condition)Sham comparatorA radiolabelled 99mTc-DTPA aerosol is generated with a jet nebuliser and is inhaled by the subject through a device (connecting tubes, filters) connecting the nebuliser with 1) a mouthpiece and 2) an intrapulmonary percussive ventilation device which is turned off. Aerosol deposition in fibrotic lung regions is characterized by SPECT imaging.
Receives: Radiation: delivery of 99mTc-DTPA aerosol
Aerosol delivery with intrapulmonary percussive ventilation (IPV condition)Active comparatorA radiolabelled 99mTc-DTPA aerosol is generated with a jet nebuliser and is inhaled by the subject through a device (connecting tubes, filters) connecting the nebuliser with 1) a mouthpiece and 2) an intrapulmonary percussive ventilation device which is turned on (frequency=1 Hz, pressure to be determined in phase 1 for each patient, in the 5-40 cm H2O range). Aerosol deposition in fibrotic lung regions is characterized by SPECT imaging.
Receives: Device: intrapulmonary percussive ventilation; Radiation: delivery of 99mTc-DTPA aerosol

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phase 1: Discomfort during IPV

    IPV is delivered at increasing pressure (from 5 cm H2O to 40 cm H2O maximum pressure) and discomfort is assessed by a 5-level Likert scale ranging from "no discomfort" to "untolerable discomfort". IPV is stopped when discomfort is rated as "difficult to tolerate" whatever the pressure.

    Measured: immediately after IPV (visit V1)

  2. Phase 2: Change between Control and IPV condition in amount of 99mTc-labelled DTPA aerosol deposited in fibrotic lung regions, reported to loaded dose

    Following aerosol delivery, chest imaging is done with a SPECT device. SPECT images are fused to high resolution computed tomography (HRCT) images. Fibrotic lung regions regions of interest (ROI) are defined by analysis of HRCT images.

    SPECT signal in fibrotic ROI is reported to the radioactive dose that was loaded in the nebulizer

    Endpoint is radioactive signal in fibrotic ROI / loaded dose

    Measured: After delivery of radiolabelled aerosol under both Control and IPV condition (Visit 4/5) i.e. up to 1 month

Secondary outcomes (10)
  1. Phase 1: Sensations associated with IPV in patients with IPF

    5-levels Likert scales ranging from "not at all" to "Very much" are used to answer the following questions : "I have trouble breathing" "This thumps to much" "This is scary"

    Measured: immediately after IPV (Visit 1)

  2. Phase 1: IPV-induced variations in dyspnea

    Dyspnea-12 scale

    Measured: Before IPV (Visit 1) and 15 days after IPV (Visit 2)

  3. Phase 1: IPV-induced variations in cough

    Leicester Cough Questionnaire

    Measured: Before IPV (Visit 1) and 15 days after IPV (Visit 2)

  4. Phase 1: IPV-induced variations in Forced Vital Capacity

    Spirometry Forced vital capacity is expressed in liters

    Measured: Before IPV (Visit 1) and 15 days after IPV (Visit 2)

  5. Phase 1: IPV-induced variations in Carbon monoxide transfer factor (DLCO)

    Single breath test DLCO is expressed in mL/min/mmHg

    Measured: Before IPV (Visit 1) and 15 days after IPV (Visit 2)

  6. Phase 1: IPV-induced variations in 5 Hz respiratory reactance

    Impulse oscillometry 5 Hz reactance is expressed as kPa.s/L

    Measured: Before IPV (Visit 1) and 15 days after IPV (Visit 2)

  7. Phase 1: Incidence of Treatment-Emergent Adverse Events

    Symptomatic pneumothorax Acute exacerbation of IPF requiring hospitalization

    Measured: immediately after IPV (Visit 1) until 15 days after IPV (V2)

  8. Phase 2 : Change between Control and IPV condition in total lung deposition of the 99mTc-labelled DTPA aerosol

    Ratio of SPECT in total lung / loaded dose

    Measured: After delivery of radiolabelled aerosol under both Control and IPV condition (Visit 5)

  9. Phase 2: Ratio of deposition of the 99mTc-labelled DTPA aerosol in fibrotic lung versus normal lung

    ROI for normally-appearing lung are defined by HRCT. Endpoint is SPECT signal in fibrotic lung ROI / SPECT signal in normally-appearing lung ROI

    Measured: After aerosol delivery in the Control condition

  10. Incidence of Treatment-Emergent Adverse Events one month after treatment

    Telephone interview to assess for :

    Symptomatic pneumothorax Acute exacerbation of IPF requiring hospitalization

    Measured: 1-month after the last aerosol delivery (V6)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Discomfort during IPV (time frame: immediately after IPV (visit V1)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Dec 2025.
