Avalglucosidase Alfa French Post-Trial Access for deltakere med Pompe Disease (PTA Avalglucosidase)
En fransk multisenter fase 4 åpen utvidelsesstudie av langsiktig sikkerhet og effekt hos pasienter med Pompe-sykdom som tidligere har deltatt i Avalglucosidase-utviklingsstudier i Frankrike
Denne langsiktige åpne sikkerhets- og effektstudien er ment å følge opp og gi tilgang til enzymerstatningsterapi (ERT) med avalglucosidase alfa etter forsøket til pasienter med Pompes sykdom i Frankrike som har fullført studie EFC14028, LTS13769 eller ACT14132 , fra markedsgodkjenning til refusjon av avalglucosidase alfa i Frankrike eller til mai 2023, avhengig av hva som kommer først.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Assessment of six-minute walk test (distance in meters and % predicted value) for late-onset Pompe disease (LOPD) and infantile-onset Pompe disease (IOPD) participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The primary measurement is the distance in meters walked by the participant on a flat, hard surface in 6 minutes.
The distance walked in meters will be recorded and the corresponding percent predicted value will be calculated.
The greater the distance (that a participant could walk in 6 minutes), the greater the endurance.
|
From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
|
Assessment of quick motor function test (QMFT) for LOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The QMFT is an observer administered test to evaluate changes in motor function.
QMFT comprises of 16 items specifically difficult for participants with Pompe disease.
Each item is scored separately on a 5-point ordinal scale (ranged from 0 to 4, higher score indicated better outcome).
Total QMFT score is obtained by adding the scores of all items and ranged from 0 (unable to perform motor function tests) to 64 (normal muscle function), higher score represented better outcome.
|
From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
|
Pulmonary function tests (forced vital capacity [FVC] (% predicted), maximum expiratory pressure/maximum inspiratory pressure) in upright and supine positions for LOPD and IOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
FVC is a standard pulmonary function test used to quantify respiratory muscle weakness. FVC is the volume of air (in liters) that can be forcibly blown out after full inspiration in the upright position, also tested in supine position. Percent of predicted FVC = (actual FVC measurement)/(predicted value of FVC) * 100. Maximum Inspiratory Pressure (MIP) is a quick and non-invasive test to measure strength of inspiratory muscles, primarily diaphragm, and allows for assessment of ventilatory failure, restrictive lung disease and respiratory muscle strength. MIP refers to how much air pressure force an individual creates by inhaling through the mouth as hard as possible. Maximum Expiratory Pressure (MEP) is a quick and non-invasive test to measure strength of expiratory muscles, primarily diaphragm, and allows for assessment of ventilatory failure, restrictive lung disease and respiratory muscle strength. MEP is the greater pressure generated during maximal expiration. |

Quality of life evaluation: 12-item short form health survey (SF-12) for LOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
SF-12, a 12 item-questionnaire, used to assess health-related quality of life in participants aged >=18 years at screening/baseline.
SF-12 consisted of 12 items, which were categorized into eight domains (subscales) of functioning and well-being: physical functioning, role-physical, role emotional, mental health, bodily pain, general health, vitality and social functioning, with each domain score ranged from 0 (poor health) to 100 (better health), higher scores indicated good health condition.
These eight domains were further summarized into 2 summary scores, physical component summary (PCS) and mental component summary (MCS).
The score range for each of these 2 summary scores was from 0 (poor health) to 100 (better health), higher scores indicated a better health-related quality of life.

Quality of life evaluation: Pompe Disease Symptom Scale (PDSS) for LOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The 24-hour recall PDSS (V1.1) is a self-administered questionnaires specifically designed to capture the symptoms impacts relevant to patients with LOPD.
The PDSS includes 12 questions with responses on a scale from 0 (none) to 10 (as bad as I can imagine) The data from PDSS scale will be analyzed separately and as a composite with PDIS scale.

Quality of life evaluation: Pompe Disease Impact Scale (PDIS) for LOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The 24-hour recall PDIS (V1.2) is a self-administered questionnaires specifically designed to capture disease impacts relevant to patients with LOPD.
The PDIS includes 15 questions with varying scales implemented depending on question type.
The data from PDIS scale will be analyzed separately and as a composite with PDSS scale.

Pompe Pediatric Evaluation of Disability Inventory (Pompe-PEDI) score for IOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The Pompe-PEDI consists of a Functional Skills Scale and a Caregiver Assistance Scale.
Both scales have 3 domains: self-care; mobility; and social function.
The Mobility Domain was selected to measure change in mobility secondary to changes in muscle strength.
The domain consists of 160 mobility items.

PedsQL score for IOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
The 23item PedsQL Generic Core Scale encompasses 4 subscales including physical, emotional, school, and social functionings. Scores are transformed to a 0-100 scale, higher scores indicate better HRQOL. Infant scale will not be used since this is a scale for up to 24 months of age and patients are older now than that. |
From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)

|
Left Ventricular Mass Index (LVMI) Z-score in IOPD participants
Tidsramme: From study enrolment to the final study visit/telephone contact, up to 4 years and 11 months (at enrolment and every 6 months)
|
Left Ventricular Mass Index (LVMI) equivalent to mean age specific LVMI plus 2 standard deviations.
