Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

In COPD patients with chronic bronchitis, it is aimed to determine whether the broncho muco cleaner balloon dilation method can provide clinical and functional benefit by causing destruction in hyperplasic goblet cells in the bronchial system. Although 2 studies have been published on this subject before, one of them is a retrospective design and the other is a pilot study consisting of only 10 patients . Therefore, it is clear that it should be supported by a controlled prospective study with more patients.

Within the scope of the research, broncho muco cleaner balloon dilatation treatment will be performed with fiberoptic bronchoscope under general anesthesia in chronic bronchitis-predominant COPD cases, and the effectiveness and reliability of the procedure will be evaluated.

Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

FEV1

From a breathing test (spirometry): how much air you can blow out in the first second. Often given as a percentage of what is expected for your age, height and sex.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    Broncho Muco Cleaner

    It will be applied to patients with a diagnosis of chronic bronchitis-predominant COPD, who cannot achieve adequate clinical and functional improvement despite optimal medical therapy. In patients who meet the patient selection criteria, anesthesia approval will be obtained before the procedure will be performed under general anesthesia

    Device: Broncho Muco Cleaner

Interventions

  • DeviceBroncho Muco Cleaner

    The endotracheal tube will be passed with a bronchoscope. During the procedure, the product is connected to the oxygen jack in the hospital, inflated and deflated, turning the thickened goblet cell layer that causes sputum production to foamy liquid. For the procedure, it will be entered through the intubation tube with a fiberoptic bronchoscope, and the airways with a diameter of 3 to 8 mm, primarily the airways, and all the respiratory tract mucosa that can be reached will be treated with a balloon in a total of 3 sessions. For these procedures, balloons selected in accordance with the diameter of the bronchi will be used in the respiratory tract. In patients who meet the patient selection criteria, intervention will be made with a balloon that inflates and deflates at the determined frequency and pressure from the subsegment level that can be reached with the bronchoscope to the inner surface of the airways proximally.
