Plain English summary of protocol

Background and study aims
Interstitial lung disease (ILD) is an umbrella term used for a large group of diseases that cause scarring (fibrosis) in the lungs, inflammation in the lungs, or a mixture of both. The scarring causes stiffness in the lungs which makes it difficult to breathe and get oxygen to the bloodstream.

As there are more than 100 different types of ILD, it is difficult to monitor and treat these conditions effectively. Currently, the diagnosis of conditions involving fibrosis/scarring relies on a number of different measures, including lung biopsy, and available treatments following diagnosis are often limited. New potential drugs are in development to treat fibrotic conditions but in order for them to work effectively, we need to better understand how this process works and be able to see the effects treatments are having directly in the lungs of patients.

In the lung, ILD has also been associated with higher levels of certain types of immune cells (alveolar macrophages). Normally, these immune cells are important in keeping the lungs free of pollutants and infection but in a large number of ILD cases, they can become ‘over-active’ and result in scarring. Developing treatments that target these immune cells could help to reverse or slow the rate of ILD progression.

Who can participate?
Adult patients with a diagnosis of suspected or confirmed ILD or bronchiectasis

What does the study involve?
This study involves a new compound that has been shown to dampen down the activity of these particular immune cells outside of the body. The next step is to find out if small amounts of this compound target these cells in the lung. This liquid compound will be delivered into the lung during a routine bronchoscopy procedure and small amounts of lung fluid or samples will be taken to assess if it is having an effect on the immune cells.

What are the possible benefits and risks of participating?
While there will be no direct benefit to the patient, we are testing this new compound to see if it has an effect on certain immune cells that are key to the progression of inflammation in the lung. The information we gain from this study will help us improve our understanding and treatment of inflammatory lung diseases.

Scientific titleMicro: A phase 0 experimental medicine study to provide early mechanistic data in humans of NLRP3/1 inflammasome inhibition after direct intrapulmonary dosing of ADS032.
Study acronymMICRO
Study objectivesThis study seeks to test the hypotheses that a novel clinical investigational agent (CIA) can attenuate alveolar macrophage (AM) inflammasome activity. This study specifically asks the question:
In treatment-naive patients with confirmed or suspected interstitial lung disease (ILD) (which includes sarcoidosis), and in patients with bronchiectasis, can this compound that is delivered to the distal lung, attenuate IL-1β secretion and other markers of inflammasome activity in AMs retrieved from bronchoalveolar lavage (BAL)?
Ethics approval(s)

Approved 27/04/2023, South Central - Oxford B Research Ethics Committee (Temple Quay House, 2 The Square, Bristol, BS1 6PN, United Kingdom; +44 207 104 8241; oxfordb.rec@hra.nhs.uk), ref: 23/SC/0077

Health condition(s) or problem(s) studiedInterstitial lung disease or bronchiectasis
InterventionThis study seeks to test the hypotheses that a novel Clinical Investigational Agent (CIA), ADS032, can attenuate alveolar macrophage inflammasome activity in the human lung. ADS032 will be microdosed into the distal lung during a bronchoscopy procedure. Up to 100 μg of ADS032 (approximately 1.5 ml) will be delivered into the distal lung using a medically approved catheter. This can be administered as single or smaller divided doses. Lung fluid samples and blood will be taken either before, during or after the procedure. Patients will be reviewed at 4 hours and their participation in the study will end at 24 hours post-procedure.

Group 1: Patients with suspected or confirmed Interstitial lung disease (ILD) or bronchiectasis will receive a microdose of the inflammasome inhibitor ADS032. Patients will also receive the equivalent regime of saline to enable them to act as their own control when samples are compared.
Group 2: Patients undergoing surgical resection of the lung will receive a microdose of ADS032.
Intervention typeDrug
Pharmaceutical study type(s)Pharmacokinetic, Pharmacodynamic
PhasePhase 0
Drug / device / biological / vaccine name(s)ADS032
Primary outcome measureTo evaluate early mechanistic data following administration of ADS032 assessed by measuring key inflammatory cytokine levels in the lung fluid of suspected or confirmed ILD patient groups measured using a variety of laboratory techniques, for example, ELISA at a single time point post the bronchoscopy
Secondary outcome measures1. Key exploratory biomarkers and their response will be evaluated (e.g. cytokines, chemokines, cell surface markers) will be measured using a variety of laboratory techniques immediately before the procedure and following the administration of ADS032 at a single time point post bronchoscopy
2. Pharmacokinetics parameters (e.g. quantification) of ADS0132 in blood and urine measured using standard laboratory techniques immediately before the procedure and 4 hours post procedure
Overall study start date01/06/2022
Completion date01/09/2024
