Amyotrophic Lateral Sclerosis Non-invasive Ventilation Exchange (ANEX)

Contribution of a Multimodal Digital Platform in the Management and Follow-up of Patients With Amyotrophic Lateral Sclerosis Treated With Non-invasive Ventilation: Randomized Controlled Study

The median survival of patients with amyotrophic lateral sclerosis (ALS) is 3 to 5 years and mortality is mainly related to respiratory failure. Non-invasive ventilation (NIV) and multidisciplinary management improve the quality of life and survival of patients. However, patients have mobility difficulties related to the progressive worsening of functional disabilities. The research team hypothesize that the use of a multimodal digital platform, including in particular telemonitoring of NIV and teleconsultation, will slow down the evolution of the disabilities of patients with ALS and improve their quality of life.

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease with a median life expectancy of 3 to 5 years. Respiratory failure due to alveolar hypoventilation is the main cause of mortality and respiratory impairment leads to a significant deterioration in quality of life. Non-invasive ventilation (NIV) improves patient quality of life, improves gas exchange and improves patient survival. NIV should be initiated early, based on symptomatology and lung function, and monitored closely to adjust device parameters. NIV is a complex intervention that must be individualized for each patient. In addition, multidisciplinary management involving different healthcare professionals, keeping the patient and caregivers at the center of the network, also allows for an improvement in the quality of life and survival of these patients. However, patients with ALS have difficulty moving around and access to care becomes more complicated as the disease progresses. This phenomenon was increased during the COVID- 19 pandemic with a more rapid functional decline. The development of new technologies should make it possible to rethink patient management, in particular through remote monitoring of NIV devices, teleconsultation, administration of questionnaires and better interprofessional organization. Several studies have confirmed the feasibility and acceptance of telemedicine solutions in this population. In this project, The research team hypothesize that the use of a multimodal digital platform will slow the progression of disability in ALS patients and improve their quality of life, in particular by improving the quality of NIV and optimizing the coordination of a multidisciplinary team.

Prospective, randomized, two-armed, interventional controlled study versus multicenter, open-label study.

A group of 29 patients with ALS will be formed to the multimodal digital platform associated with Non Invasive Ventilation (NIV) and usual management Patients will be treated with NIV equipment from the manufacturer LOWENSTEIN and will benefit from the usual follow-up carried out at the reference center of Montpellier University Hospital.

A group of 29 patients with ALS will be formed : control group following usual management including NIV. Patients will be treated with NIV equipment from the manufacturer LOWENSTEIN and will benefit from the usual follow-up carried out at the reference center of Montpellier University Hospital.

Patients in the experimental group will have access to a multimodal digital platform (m-Rehab®). The solution includes a website and an application available on smart phones for the patient and caregivers. Patients and caregivers will have access to educational content about the condition and its treatments, NIV compliance data, digital group educational workshops, secure messaging and video conferencing. All the professionals forming the patient's circle of care will be able to have access to the solution, after the patient's authorization. The circle of care, in a non-exhaustive way, includes specialist doctors, the general practitioner, the staff of the reference center of the Montpellier University Hospital, the physiotherapist, the speech therapist, the dietician and the psychologist.

Difference in change in functional abilities between the experimental and control groups over 6 months of follow-up.

Difference in variation of the functional capabilities assessed by the Amyotrophic lateral sclerosis functional rating scale (ALSFRS) score at Baseline (D0) and 6 months between the experimental group and the control group. A scale to determine different aspects of functionality in patients with ALS, minimum 0 points, maximum 48 points, derived from a questionnaire with 12 questions, each of which can yield up to 4 points, higher score indicates better functionality

Quality of life assessed by the EuroQol-5 Dimensions (EQ5D) scale. The descriptive system has five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each described by five levels of intensity ("no problems", "slight problems", "moderate problems", "severe problems" and "extreme problems or complete inability"). This decision results in a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.
