Clinical trials

Background and study aims: Lung cancer is a leading cause of cancer-related deaths worldwide. Patients with non-small cell lung cancer often undergo lung surgery to remove the tumor. Before surgery, patients may participate in prehabilitation programs to improve their physical fitness and overall health, which can lead to better surgical outcomes. Traditionally, these programs are conducted entirely in specialized centers, but places are scarce, limiting access. This study aims to compare the relative effectiveness of a hybrid prehabilitation program, combining home-based and center-based sessions, with the standard center-based program. The primary goal is to assess changes in aerobic capacity, measured by peak oxygen uptake, before and after participation in the prehabilitation program. Who can participate? Adults over 18 years old who are scheduled for lung resection surgery to treat diagnosed or suspected non-small cell lung cancer can participate. Participants should be referred for respiratory prehabilitation in a preoperative context and live at home with another adult, present during exercise sessions. The surgery date should be either not yet established at the time of inclusion or scheduled for at least four weeks later. Participants should have a peak oxygen uptake of less than 20 ml/kg/min, be beneficiaries of a social security system, and have read and understood the information letter and signed the consent form. What does the study involve? This is a single-center, randomized controlled trial with two groups: Center-based prehabilitation group: Participants will attend 15 sessions over three weeks (five sessions per week) at the center. The program includes an initial session of therapeutic education and exercise training, followed by 13 prehabilitation sessions, and a final session with educational reinforcement. Hybrid prehabilitation group: Participants will have three sessions at the center and 13 sessions at home over the same period. They will be provided with equipment such as a cycle ergometer, pulse oximeter, physical activity sensor, and a tablet application (TELEREHAPP) to guide and monitor their home-based exercises. Regular phone contact with healthcare professionals will be maintained for support. All participants will undergo assessments before and after the program, including an incremental exercise test on a cycle ergometer to measure peak oxygen uptake. What are the possible benefits and risks of participating? Participants may experience improved physical fitness, which could lead to better surgical outcomes and reduced postoperative complications. The study will also provide insights into the relative effectiveness of hybrid prehabilitation, potentially offering more flexible options and facilitating access to care for future patients. Risks may include muscle soreness, fatigue, or injury related to exercise, independently of group allocation. All exercise sessions will be supervised or monitored to minimize these risks. Participants will receive instructions on how to perform exercises safely and will be encouraged to report any adverse effects promptly.

Chronic obstructive pulmonary disease is a long-term lung condition that causes breathing difficulties. People living with this disease often feel short of breath, especially during physical activity, which can make daily tasks more challenging. This breathlessness is partly caused by mucus accumulation within the airways and air getting trapped in the lungs. Both of these reduce the amount of fresh air that can enter with each breath and increase the effort required to breathe. To manage symptoms, people with chronic obstructive pulmonary disease may use medications, oxygen therapy, or be referred to pulmonary rehabilitation programs. These programs often include exercise training, self-management strategies, and airway clearance techniques. While chest physiotherapists typically guide patients in these techniques, certain medical devices can also help individuals manage their condition independently at home. One such device uses a method called intermittent intrapulmonary deflation, which involves applying gentle pressure changes through a mouthpiece to help loosen mucus and release trapped air from the lungs. Although some individuals already use this kind of device as part of their daily care, more scientific evidence is needed to determine whether the improvements in airway clearance and reduced air trapping actually lead to measurable relief of breathlessness. The goal of this clinical trial is to find out whether this type of medical device designed to remove airway mucus and trapped air in the lungs (using intermittent intrapulmonary deflation) can help reduce breathlessness (dyspnea) after physical activity in people with COPD. The main questions this study aims to answer are: * Does using the device at home for one week reduce the intensity of breathlessness after walking? * Does it also improve walking distance, reduce the feeling of muscle fatigue, or increase satisfaction with the airway clearance method? Researchers will compare the active device to a placebo device that looks and feels identical but does not deliver the active treatment. This comparison will help determine whether the observed effects are due to the device itself or other factors such as expectations or chance. Participants in this study will be adults diagnosed with moderate to very severe chronic obstructive pulmonary disease. All participants must have recently completed a pulmonary rehabilitation program, continue to experience breathlessness while walking, and show signs of lung hyperinflation (when air remains trapped in the lungs). People will not be included if they have other serious health conditions that could make walking difficult or unsafe, or if they have any contraindications to using the device. Participants who agree to participante in the study will: * Attend a visit at the pulmonary rehabilitation center for baseline testing and to learn how to use the device; * Be randomly assigned to use either the active device or the placebo device at home for 7 days; * Return to the center for walking tests, lung function tests, and questionnaires about breathing and fatigue; * After a one-week break, use the device with alternative settings (the one not used in the first phase) for another 7 days; * Complete a final visit at the end of the study to repeat the same tests. Participants will also be invited to take part in an ancillary study during their first clinic visit to examine how a single session with the device affects breathlessness immediately after walking. This research will help determine whether this non-pharmacological, device-based method of clearing mucus and reducing trapped air can bring meaningful improvement in breathlessness for people with chronic obstructive pulmonary disease, especially when used at home. If effective, it may offer a simple and convenient way to help people breathe more comfortably during everyday activities. Participants will receive compensation for their time and travel.

Background and study aims: Chronic obstructive pulmonary disease is a leading cause of mortality worldwide. Pulmonary rehabilitation is recommended for patients to improve dyspnea, exercise capacity, and quality of life. Paradoxically, as few as 5 to 10% of eligible patients undergo pulmonary rehabilitation due to barriers such as transportation difficulties and limited availability of pulmonary rehabilitation centers. Home-based pulmonary rehabilitation using advanced telehealth technologies (telerehabilitation) may offer a solution to improve access. This study aims to compare the relative effectiveness of a home-based telerehabilitation program with center-based program. The primary objective is to assess changes in exercise endurance capacity, measured by endurance time, before and after participation of the rehabilitation program. Who can participate? Adults between 45 and 80 years old who are referred for pulmonary rehabilitation and have a confirmed diagnosis of chronic obstrucitve pulmonary disease (GOLD stage II to IV) at any of the participating centers are eligible to participate, whether or not they use oxygen during exercise. Participants must live at home with another adult who is present during exercise sessions. They must not have experienced any exacerbation in the month prior to study inclusion, nor have participated in a pulmonary rehabilitation program within the past year. Participants must not have any scheduled surgery within the next four months, including surgery for lung cancer resection. They must not have active cancer, and must not present any contraindication to exercise or any condition that would limit their ability to use the telerehabilitation system. Eligible participants must be beneficiaries of a social security system and must have read and understood the information letter and signed the informed consent form. What does the study involve? This is a multi-center, randomized controlled trial with two groups: Center-based rehabilitation group: Participants will attend 24 sessions over eight weeks (three sessions per week) at the center. The program includes an initial session of therapeutic education and exercise training, followed by 24 rehabilitation sessions, and a final assessment with educational reinforcement. Home-based rehabilitation group: Participants will have 24 sessions at home over the same period (eight weeks). The program includes an initial in-center assessment session, followed by 24 rehabilitation sessions and a final in-center session for assessment. They will be provided with equipment such as a cycle ergometer, pulse oximeter, physical activity tracker, and a tablet application (TELEREHAPP) to guide and monitor their home-based exercises. Regular phone contact with healthcare professionals will be maintained for support. All participants will undergo assessments before and after the program, including a constant work rate endurance test on a cycle ergometer to measure exercise endurance capacity. What are the possible benefits and risks of participating? Participants may experience improved physical fitness, which could lead to better dyspnea management and better quality of life. Risks may include muscle soreness, fatigue, or injury related to exercise, independently of group allocation. All exercise sessions will be supervised or monitored to minimize these risks. Participants will receive instructions on how to perform exercises safely and will be encouraged to report any adverse effects promptly.
