NCT ID: NCT06406452 Not yet recruiting - Clinical trials for Tracheobronchomalacia

Bioresorbable Airway Splint Pivotal Clinical Trial

Start date: May 2024
Phase: N/A
Study type: Interventional

The purpose of this study is to learn if a three-dimensional (3D) printed airway splint device made to hold open a collapsing airway is a safe and effective treatment of Tracheobronchomalacia (TBM) in children. The airway splint is bioresorbable, meaning the child's body will absorb the splint over about five years.

Portable Continuous Positive Airways Pressure (CPAP) in Excessive Central Airway Collapse (ECAC) Study

Start date: July 27, 2023
Phase: N/A
Study type: Interventional

This study will investigate the role of a portable Continues Positive Airway Pressure device (pCPAP) in management of patients with symptomatic Excessive Central Airway Collapse (ECAC). ECAC is characterised by complete or partial collapse of central airways on exhalation. In some cases, this can cause persistent breathlessness and severely limited exercise capacity. Current treatment options for ECAC are very limited. Standard assistive breathing devices such as CPAP machines are sometimes used to relieve symptoms at night or at rest. This does not address breathlessness during activity which drives accumulation of disability over time. The main aims of this project are to assess the effect of a portable CPAP (pCPAP) device on exercise capacity and symptoms and evaluate the feasibility of wearing pCPAP at home during routine activities. Lightweight battery-powered portable CPAP devices have been recently developed to facilitate travel to remote areas by people with Obstructive Sleep Apnoea (OSA). Patients with ECAC can wear them during physical activity to prevent airway collapse but their potential benefits have not been evaluated in clinical trials. For this study, the investigators will recruit 20 patients with ECAC who will attend for two study visits 4-6 weeks apart in a single centre (The Royal Papworth Hospital). The primary outcome measure will be a shuttle walk test performed repeatedly with and without pCPAP in a randomised order. Secondary outcomes will include assessment of activity level, breathlessness, quality of life ,pCPAP usage and its acceptability. The study will evaluate a pragmatic way of CPAP titration and application. Previously acquired diagnostic baseline computed tomography (CT) scans will be analysed with a novel Functional Respiratory Imaging (FRI) tool. This software tool will enable retrospective reflections on the changes occurring within the lungs for patients with ECAC. This may help identify predictive features of potential pCPAP responders and inform future use.

NCT ID: NCT05299008 Recruiting - Clinical trials for Tracheobronchomalacia

The Effect of Bethanechol on Tracheobronchomalacia

Start date: August 11, 2022
Phase:
Study type: Observational

The primary aim of this study is to determine if work of breathing estimated using swing Edi will be improved following initiation of bethanechol in infants with tracheobronchomalacia. The investigators hypothesize that work of breathing will be improved in infants with tracheobronchomalacia estimated by a 20% mean decrease in swing Edi following initiation of bethanechol.

NCT ID: NCT04217603 Recruiting - Clinical trials for Tracheobronchomalacia

Effect of CPAP on 6-Minute Walk Test Outcomes in Patients With ECAC

Start date: March 1, 2023
Phase: N/A
Study type: Interventional

The purpose of this protocol is to perform a prospective, randomized, double-blinded, pacebo-controlled clinical trial to determine the influence of a non-invasive positive pressure ventilation device on exercise capacity and symptoms in adult patients with ECAC. Primary outcome will include the total distance traversed by the study subject during a standard 6-minute walk test, and secondary outcomes will include peak flow measurement and symptom reporting before and after the exercise testing. The study will focus on the use of continuous positive airway pressure (CPAP) device. CPAP is FDA-approved for the treatment of various medical conditions, including obstructive sleep apnea and heart failure, but is not FDA-approved for the treatment of ECAC. The study will enroll 32 ambulatory study subjects with confirmed ECAC at the BIDMC, and each study subject will be monitored for up to 3 months.

NCT ID: NCT04169282 Completed - Clinical trials for Tracheobronchomalacia

PEEP Mask for Tracheobronchomalacia-Induced Cough

Start date: August 30, 2021
Phase: N/A
Study type: Interventional

This study aims to determine if an expiratory resistance device that delivers non-invasive positive expiratory pressure (nPEP) will reduce or stop coughing, reduce airway resistance and improve quality of life in patients with tracheobronchomalacia (TBM) who are not candidates for tracheal stenting.

NCT ID: NCT03043898 Terminated - Asthma Clinical Trials

Mapping Sound Propagation Through the Human Lung for Better Diagnosis

Start date: February 14, 2018
Phase:
Study type: Observational

This study investigates the propagation of sound from a source in the chest to the chest wall. The methodology of the study will be to place a sound source at a known location in the chest and measure the acoustic response on the posterior chest wall with an acoustic sensor array. The sound source will be created by playing sound down the working channel of a bronchoscope and located anatomically using direct imaging. Subjects will be selected for the study by asking patients undergoing a bronchoscopy procedure whether they would be willing to take part in the experiment in addition to their standard procedure. Procedures will take place in the Bronchoscopy Unit at Addenbrooke's hospital in Cambridge. The Unit runs regional speciality clinics in severe chronic obstructive pulmonary disease, asthma, lung cancer, bronchomalacia and interstitial lung disease and has a nationally significant interventional bronchoscopy service. A subsidiary part of the study (Part A) will collect sound recordings from healthy volunteers and patients with common respiratory diseases using the same acoustic sensor array. This is to create a database of lung sounds and quantify inter-subject variability. The study will last approximately 30 months.

NCT ID: NCT02982876 Enrolling by invitation - Clinical trials for Tracheobronchomalacia

Airway Stents for Excessive Dynamic Airway Collapse

Start date: December 2016
Phase: N/A
Study type: Interventional

Airway stents are used as standard of care to identify which patients with excessive dynamic airway collapse will benefit from a definitive surgical treatment. However, the specific way in which these stents are effective has not been tested. The purpose of this research study is to determine the effectiveness of airway stents when used in the airways of patients with severe symptomatic excessive dynamic airway collapse compared to patients with severe symptomatic excessive dynamic airway collapse that do not receive airway stent.
