Impact of Inhaled PT003 on Complexity and Variability of Tidal Breathing and Oscillatory Mechanics in Stable COPD Patient
Stopped: Following Brexit and the unavailability of the experimental drug (PT003) in France, the study was terminated prematurely.

Plain-language summary
Prospective, single-arm, open label, multicentre, phase II pilot study to evaluate the immediate and short term (one month) impact of a new long acting double bronchodilator on innovative parameters in stable and moderate to severe COPD patients.
* Variability and complexity of resting tidal breathing
* Oscillatory resistance and reactance of airways Tidal volume variability and complexity is decreased in airway obstruction and is expected to improve with a bronchodilator treatment, together with lung mechanics.
The relationship with changes in dyspnea and conventional pulmonary function tests is the second aim of study.
After baseline assessment of these parameters, clinical and lung function evaluation will be performed 2 hours post-drug (peak drug effects). Patients will continue treatment with PT003 for 4 weeks. On Day 30, the same clinical and lung function assessments will be performed pre (trough) and 2h-post dose in order to obtain after-treatment measurements.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Female or male subjects aged 40-75 years Documented COPD in stable condition FEV1 between 30 % and 70 % predicted (post bronchodilator) Significant dyspnea with a mMRC dyspnea scale
Exclusion Criteria:
* History or current diagnosis of asthma or ACO (asthma-COPD overlap syndrome)
* Respiratory infection or COPD exacerbation within 6 weeks (2 months if it resulted in hospitalization) prior to screening
* Clinically significant or relevant cardiovascular conditions, laboratory tests, electrocardiogram (ECG) parameters
* Severe renal impairment eGFR \< 30
* Narrow-angle glaucoma that, in the opinion of the Investigator, has not been adequately treated.
* Symptomatic prostatic hypertrophy or bladder neck obstruction/urinary retention that is clinically significant
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
