About this study
Official title: Respreeza® Self-administration and Learning Program (AmAREtTI Study- Auto-Administration de Respreeza® et Programme d'apprenTIssage)
According to the Respreeza® Summary of Product Characteristics, the initial infusions must be administered under the supervision of a health professional experienced in the treatment of alpha-1 antitrypsin deficiency, although subsequent infusions may be administered at home by the person responsible for care or by the patient.
Clinical data on self-administration of Respreeza® are however limited and the grounds for self-administration are left to the assessment of the attending physician, who needs to ensure that appropriate training is delivered.
In this context, CSL Behring would like to run a clinical study in order to assess the effectiveness of a home self-administration learning program in terms of switching to self-administration, and the long term maintenance of this administration.
- Conditions
- Alpha-1 Antitrypsin Deficiency
- Medical subject headings
- alpha 1-Antitrypsin Deficiency
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of patients who switch to self-administration without the presence of a nurse at the end of the learning program
A patient will be permitted to switch to self-administration without the presence of a nurse if the following conditions are met:
- Three consecutive successful self-administrations by the patient in the presence of the nurse but without assistance during the learning phase.
- Validation of the learning grid The percentage is based on number of patient switching to self-administration and remains in self-administration 12 months after
Measured: Up to 8 weeks
Percentage of patients who switch to self-administration without the presence of a nurse
Measured: Up to 12 months
Secondary outcomes (10)
Percentage of patients who switch to self-administration without the presence of a nurse
A patient will be permitted to switch to self-administration without the presence of a nurse if the following conditions are met:
- Three consecutive successful self-administrations by the patient in the presence of the nurse but without assistance during the learning phase.
- Validation of the learning grid The percentage is based on number of patient switching to self-administration
Measured: Up to 8 weeks
Patient characteristics
Socio-demographic data, disease history, concomitant treatments, substitution protocol, percentage of theoretical forced expiratory volume at one second (FEV1), diffusing capacity of lung for carbon monoxide (DLCO), distance from home to hospital, type of follow-up (in hospital, in surgery)
Measured: At inclusion
Degree of autonomy
The change in the degree of autonomy will be defined as the difference between the autonomy assessed at 12 months and inclusion according to an EVA
Measured: At inclusion and 12 months after self-administration
The time frame for autonomy
The time to achieve autonomy will be defined by the time between the first learning session for self-administration and the first self-administration without nurse.
Measured: Up to 12 months
Evolution of patients Quality of Life with Saint George's Respiratory Questionnaire (SGRQ)
Measured: Up to 12 months
Patients satisfaction for treatment administration by a nurse and for self-administration
Satisfaction for treatment administration by a nurse will be assessed at inclusion by visual analog scale (VAS) Satisfaction for self-administration will be assessed after 12 months after the 1st self-administration or in case of study withdrawal by VAS
Measured: Up to 12 months
Satisfaction about learning program
Satisfaction about learning program will be assessed at the end of the learning program by VAS
Measured: Up to 8 weeks
Tolerance and safety
General and local tolerance at the administration site assessed by the nature and number of adverse events (AEs) and immunoglobulin E impaired gas exchange (IGEs).
Measured: Up to 12 months
Compliance/Observance
Compliance/observance measured by the number of scheduled and unrealized sessions.
Measured: Up to 8 weeks
Determining factors for switch to self-administration
Determining factors that may be associated with the transition to self-administration (demographics, disease history, concomitant treatments, substitution protocol, FEV1, QoL at inclusion, duration of learning program).
Measured: Up to 8 weeks

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

Clinical data on self-administration of Respreeza® are however limited and the grounds for self-administration are left to the assessment of the attending physician, who needs to ensure that appropriate training is delivered.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of patients who switch to self-administration without the presence of a nurse at the end of the learning program (time frame: Up to 8 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2025.
