The onset of smartphone usage has provided new opportunities for managing patients outside the walls of healthcare facilities. The development of asthma-specific smartphone applications represents an excellent area for partnership between developers and medical teams for delivering therapeutic education at the required time and in a personalised way. Within this context, the overall goal of the AsthmaTrain study is to perform a first, small pilot study comparing a new French-language chat-bot guided asthma patient education programme (the 'Vik' application) with the classic, authority-approved patient education program at the University Hospitals of Montpellier, Montpellier, France.
The primary objective is to compare a population of adult patients with asthma and participating in a standard patient education programme with a similar population participating in Vik-guided education programme in terms of change in overall scores on the Asthma Quality of Life Questionnaire (AQLQ).
Secondarily, the following will also be compared between the two study arms:
Finally, because education intervention success may depend on patient-specific characteristics, an ancillary study will compare the following baseline traits between the 50% best intervention responders in either arm:

| Standard patient education | Other | The comparator intervention is the usual therapeutic training for patients (ETP) cursus currently used in the General Pulmonology unit at the Arnaud De Villeneuve Hospital, Montpellier, France and approved by the French Regional Health Authority for the Occitanie Region [Agence Régional de Santé Occitanie]. |

| Change in the total AQLQ score | The Asthma Quality of Life Questionnaire (AQLQ) is a 32-item, 4-domain instrument that can either be self- or interviewer-administered. The recall-time is two weeks. The four domains covered are: (i) symptoms (11 items), (ii) activity limitation (12 items, 5 of which are individualized), (iii) emotional function (5 items), and (iv) environmental exposure (4 items). Each item is ranked by the patient using a 7-point Likert scale ranging from 1 (severely impaired) to 7 (not impaired at all). Scores range from 1 to 7, higher scores indicate better quality of life and a minimally important difference (for overall scores and for each sub-domain) has been established at 0.5. | baseline to 6 months |

The general goal is to make the study data available to interested researchers as well as to provide proof of transparency for the study.
Data will be made available to persons who address a reasonable request to the study director.
Individual participant data (and an accompanying data dictionary) will be de-identified and potentially further cleaned or aggregated as the investigators deem necessary to protect participant anonymity.
The study protocol, participant information materials, and paper case report form will also be made available to the public.
Datasets that underlie the results reported in the article (text, tables, figures, and appendices) can be requested after the publication process has been completed.
The protocol will be published in an open-access journal. The remaining documents will be made available on the Open Science Framework as they are finalized.

This prospective, randomized (1:1), controlled, pilot trial with a single-Zelen consent procedure will compare changes in quality of life, asthma control, lung function and health resource consumption between one group of patients with asthma participating in a classic treatment education program (the "standard education" arm) with a similar, second group of patients participating in a novel, chatbot-guided treatment education program (the "Vik" arm).

This protocol aims to compare two different ways of engaging with the patient and teaching. The notion of blinding per se is not adapted to this protocol, which is carried out, for all practical purposes, in an "open" fashion. Nevertheless, the Zelen randomisation procedure, which aims to maintain the comparator arm ignorant of the existence of the experimental arm in order to avoid "resentful demoralisation" effects, may also result in a partial blinding effect.

| Chatbot patient education | Other | The experimental intervention consists in providing the patient with access to a specific version of the "Vik-Asthme" chat bot for the duration of the study. Should the patient be unable to use or refuse to use the chatbot, the reasons for refusal will be documented and the patient will proceed with the comparator intervention. |

| Change in the 'activity limitation' domain of the AQLQ from baseline to six months | The Asthma Quality of Life Questionnaire (AQLQ) is a 32-item, 4-domain instrument that can either be self- or interviewer-administered. The recall-time is two weeks. The four domains covered are: (i) symptoms (11 items), (ii) activity limitation (12 items, 5 of which are individualized), (iii) emotional function (5 items), and (iv) environmental exposure (4 items). Each item is ranked by the patient using a 7-point Likert scale ranging from 1 (severely impaired) to 7 (not impaired at all).

| Change in the ACQ-5 score | The ACQ-5 is a shortened version of the ACQ that assesses asthma symptoms (night-time waking, symptoms on waking, activity limitation, shortness of breath, wheezing) omitting the forced expiratory volume in 1 second measurement and short acting beta antagonist use from the original ACQ score. Patients are asked to recall how their asthma has been during the previous week by responding to 5 symptom questions. Questions are weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled). The mean ACQ-5 score is the mean of the responses. Mean scores of ≤0.75 indicate well-controlled asthma, scores between 0.75 and <1.5 indicate partly controlled asthma, and a score ≥1.5 indicates not well controlled asthma . Individual changes of at least 0.5 are considered to be clinically meaningful. | baseline to 6 months |

| Change in the EQ-5D-5L score | In its original version, this self-administered questionnaire consists of two pages: the first contains the EQ-5D descriptive system and the second a visual analogue 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"). The respondent must indicate one intensity level for each dimension. | baseline to 6 months |
