NCT ID NCT07068438

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests a device that delivers gentle electric pulses to the airways to reduce chronic bronchitis symptoms in adults with COPD. About 210 participants will either receive the real treatment or a sham procedure. The goal is to see if the treatment improves breathing and quality of life.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Pulsed electric field ablation system (device)
What this could lead to
If it works, this could provide a new, non-drug option to reduce coughing and mucus in people with COPD and chronic bronchitis.
What could go wrong
This is an early-stage, sham-controlled trial, so the real benefit is still unproven. The procedure involves two lung treatments, which carry risks like infection or breathing problems.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Subject's age is ≥35 years and ≤80 years. 2. Patient has chronic bronchitis, defined as productive cough for three months in each of two successive years, whereas other causes of productive cough have been ruled out. 3. Patient has a CAT score ≥ 10. 4. Patient has an SGRQ score ≥ 25. 5. Patient's responses to the first two questions of the CAT instrument sum to ≥ 7 points or the sum is 6 points and the patient's total CAT score is \> 20 points. 6. Patient has FEV1/FVC \< 0.70. 7. Patient has a pre-procedure post-bronchodilator FEV1 percent predicted of ≥ 30%. 8. Patient is receiving guideline directed pharmacotherapy which includes one or more long acting bronchodilator (LAMA, LABA) with or without an inhaled corticosteroid for at least 8 weeks prior to randomization, unless the patient has attempted such therapy within the past 1 year without significant clinical response or had an adverse reaction. 9. In the opinion of the Primary investigator, patient is able to undergo 2 bronchoscopies under general anesthesia and is able to adhere to the study follow-up schedule. 10. Informed consent signed by the patient or legal representative. Exclusion Criteria: 1. Patient has known unresolved lower respiratory tract infection (e.g., pneumonia, mycobacterium avium-intracellulare infection (MAI), fungus, tuberculosis). 2. Patient has a steroid-dependent condition requiring \>10 mg of oral corticosteroid per day. 3. Patient has any implantable electronic device (e.g., pacemaker, cardioverter defibrillator) that cannot be turned off during the procedure. 4. Patient has a history of ventricular tachy-arrhythmia or clinically significant atrial tachyarrhythmia within the past two years, or sinus bradycardia with a heart rate of under than 45 beats per minute, unless the arrhythmia has been treated and/or patient is in regular rhythm during the screening phase. 5. Subject has lung cancer. 6. Patient has a pulmonary nodule or cavity that in the judgement of the Primary investigator may require intervention during the course of the study. 7. Patient had prior lung surgery, such as lung transplant, LVRS, lobectomy, lung implant/prosthesis, metal airway stent, valves, coils or bullectomy. 8. Patient has emphysema of greater than or equal to 50% as quantified on baseline HRCT scan as determined by the CT Core Lab. 9. Patient has asthma based on Global Initiative for Asthma (GINA) criteria. 10. Patient has clinically significant bronchiectasis influencing the patient's clinical symptoms of cough and phlegm. 11. Patient has actively smoked (including tobacco, marijuana, e-cigarettes, vaping, etc.) within the last 2 months. 12. Patient is unable to walk over 225 meters in 6 minutes. 13. Patient has a serious medical condition that, in the Primary investigator's opinion, could compromise patient safety or confound the interpretation of the patient's response to therapy (e.g., congestive heart failure, cardiomyopathy, or myocardial infarction in the past year, renal failure, liver disease, cerebrovascular accident within the past 6 months, uncontrolled diabetes (HbA1c \>8%), uncontrolled hypertension (diastolic BP \>100mmHg) or autoimmune disease requiring treatment with immunosuppressant medications or a disease requiring chemotherapy). 14. Patient has uncontrolled GERD. 15. Patient has known severe pulmonary hypertension (pulmonary artery SP ≥ 50 mmHg). 16. Patient has a known sensitivity to medication required to perform bronchoscopy (i.e., lidocaine, atropine, benzodiazepines). 17. Patient is pregnant, nursing, or planning to get pregnant during study duration. 18. Patient is currently participating in another clinical study involving an investigational product. 19. Patient is receiving anticoagulation for a cardiovascular indication and, in the Primary investigator's opinion, unable to suspend anticoagulant medications (i.e., aspirin, clopidogrel, warfarin) during bronchoscopy in accordance. 20. Patient has known airway colonization with drug-resistant bacteria such as Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, Burkholderia cepacia complex, Mycobacterium tuberculosis, Mycobacterium abscessus, Trichoderma, or other significant fungi.
