Current Primary Outcome Measures (submitted: February 6, 2020)

• 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 ]
  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
• Percentage of patients who switch to self-administration without the presence of a nurse [ Time Frame: Up to 12 months ]

• Original Primary Outcome Measures: Same as current

Current Secondary Outcome Measures (submitted: February 6, 2020)

• Percentage of patients who switch to self-administration without the presence of a nurse [ Time Frame: Up to 8 weeks ]
  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
• Patient characteristics [ Time Frame: At inclusion ]
  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)
• Degree of autonomy [ Time Frame: At inclusion and 12 months after self-administration ]
  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
• The time frame for autonomy [ Time Frame: Up to 12 months ]
  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.
• Evolution of patients Quality of Life with Saint George's Respiratory Questionnaire (SGRQ) [ Time Frame: Up to 12 months ]
• Patients satisfaction for treatment administration by a nurse and for self-administration [ Time Frame: Up to 12 months ]
  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
• Satisfaction about learning program [ Time Frame: Up to 8 weeks ]
  Satisfaction about learning program will be assessed at the end of the learning program by VAS
• Tolerance and safety [ Time Frame: Up to 12 months ]
  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).
• Compliance/Observance [ Time Frame: Up to 8 weeks ]
  Compliance/observance measured by the number of scheduled and unrealized sessions.
• Determining factors for switch to self-administration [ Time Frame: Up to 8 weeks ]
  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).

Descriptive Information

• Official Title: Respreeza® Self-administration and Learning Program (AmAREtTI Study- Auto-Administration de Respreeza® et Programme d'apprenTIssage)

Brief Summary

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.
