EXERTION: Efficacy and Safety of Broncho Muco Cleaner Balloon Dilation Therapy
Study Details
Study Description
Brief 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.

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
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.

Outcome Measures
Primary Outcome Measures
- Reliability of the procedure - Safety [52 weeks]
Reliability of the procedure (adverse events occurring) for 52 weeks post-procedure.
- Patients' Tolerence - mMRC dyspnea scale [52 Weeks]
Within the scope of the KBB001 Exertion Study, the broncho muco cleaner procedure to be applied to the patients will be performed with fiberoptic bronchoscopy under general anesthesia. Any undesirable event that may be associated with and after the transaction will be recorded. Primary evaluation criteria in determining the Processing efficiency of your device.
- Patients' Tolerence - COPD Exacerbation Number (severity of exacerbation will be indicated as mild, moderate, severe.) [52 Weeks]
Within the scope of the KBB001 Exertion Study, the broncho muco cleaner procedure to be applied to the patients will be performed with fiberoptic bronchoscopy under general anesthesia. Any undesirable event that may be associated with and after the transaction will be recorded. primary evaluation criteria in determining the Processing efficiency of your device
- Patients' Tolerence - St George Respiratory Questionnaire [52 Weeks]
Within the scope of the KBB001 Exertion Study, the broncho muco cleaner procedure to be applied to the patients will be performed with fiberoptic bronchoscopy under general anesthesia. Any undesirable event that may be associated with and after the transaction will be recorded. primary evaluation criteria in determining the Processing efficiency of your device.
- Patients' Tolerence - 6 min walking test [52 Weeks]
Within the scope of the KBB001 Exertion Study, the broncho muco cleaner procedure to be applied to the patients will be performed with fiberoptic bronchoscopy under general anesthesia. Any undesirable event that may be associated with and after the transaction will be recorded. primary evaluation criteria in determining the Processing efficiency of your device.
- Patients' Tolerence - Pulmonary Function Test (FEV1, FVC values in (lt) and (%) values as well as FEV1/ FVC rate (in %) [52 Weeks]
Within the scope of the KBB001 Exertion Study, the broncho muco cleaner procedure to be applied to the patients will be performed with fiberoptic bronchoscopy under general anesthesia. Any undesirable event that may be associated with and after the transaction will be recorded. primary evaluation criteria in determining the Processing efficiency of your device.
- Detection of Execerbations [52 weeks]
COPD Exacerbation (COPD Exacerbation) is one of the most important problems of COPD patients and includes the risk of mortality and mirdit. It is expected that the number of exacerbations of the patients will decrease with the broncho muco cleaner balloon treatment. The number and severity of exacerbations (mild, moderate, severe) at each visit of the patient will be noted to assess the effect of treatment on exacerbations.
- Quality of Life for the device [52 Weeks]
A St George quality of life survey will be conducted and recorded. Every 4-point change in the SGRQ questionnaire will be considered minimal clinical significance.
Secondary Outcome Measures
- Improvement in functional parameters - 6 Minute Walk Test (V1-V6) [52 weeks]
- 6 Minute Walk Test (V1-V6)
- Improvement in functional parameters - Pulmonary Function Test (V1-V2-V3-V4-V5-V6) [52 weeks]
- Pulmonary Function Test (V1-V2-V3-V4-V5-V6)
- Adverse events [52 weeks]
Adverse events seen (AE)
- Changes in laboratory test results [52 weeks]
Change in blood chemistry tests and hemogramcompared to baseline and EoT
