Descrizione dettagliata

This is a multi-center, observational, prospective, longitudinal registry study, designed to collect safety data and to explore long-term clinical impact of AGAMREE® on quality of life, as assessed by standardized patient-reported outcome measures (QoL questionnaires) in male patients aged 2 years and older with DMD.

Primary Objective is to collect additional information on the safety of long-term treatment with AGAMREE® in male patients aged 2 years and older with Duchenne muscular dystrophy (DMD) as determined by:

Growth parameters Body mass index (BMI) Musculoskeletal assessments Ophthalmological assessments Cardiovascular assessments Pubertal development assessments Adverse events (AEs)

Secondary Objective is to explore long-term clinical impact of AGAMREE® on quality of life, as assessed by standardized patient-reported outcome measures (QoL questionnaires).

This registry will be conducted in the US, at approximately 40 sites known to treat and follow patients with DMD. The registry plans to enroll approximately 250 male patients aged 2 years and older with DMD.

Patients will be followed for approximately 5 years in the registry and will return to the site for Yearly Follow-up Visits (+/- 30 days) for assessments. Information on some historical and ongoing standard of care treatment and procedures for management of DMD will also be collected.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Height z-score
Lasso di tempo: At Enrollment Visit (baseline), and at each Yearly Follow-up Visit (for up to 5 years).

Standing height in participants 2 years of age and older will be measured using a stadiometer mounted at a right angle between a level floor and against a straight, vertical surface. When transitioning from recumbent length to standing height measurements in participants between 2 to 3 years of age, measure both length and height. If collecting standing height measurements is not feasible, height will be estimated using arm span measurements. To estimate the height, the arm span will be measured from fingertip to fingertip with arms fully extended horizontally. The same standardized technique will be used at all study visits.
At Enrollment Visit (baseline), and at each Yearly Follow-up Visit (for up to 5 years).
Change in BMI z-score
Lasso di tempo: At Enrollment Visit (baseline), and each Yearly Follow-up Visit (for up to 5 years)

Weight will be measured according to the site's standard of care procedures. For ambulatory patients, this typically involves a standing scale; for non-ambulatory patients, a wheelchair or bed scale may be used. Sites should document the method used at each visit.
At Enrollment Visit (baseline), and each Yearly Follow-up Visit (for up to 5 years)
Change in North Star Ambulatory Assessment from baseline
Lasso di tempo: At Enrollment visit, and each Yearly Follow-up Visit (for up to 5 years).

The North Star Ambulatory Assessment is a clinical assessment scale specifically designed to measure functional ability in ambulant male patients with DMD. The North Star Ambulatory Assessment consists of 17 scored items and 2 timed tests, including the Time to Run/Walk Test and the Time to Stand Test. The Time to Run/Walk Test measures the time (in seconds) that it takes the patient to run or walk 10 meters. The Time to Stand Test measures the time (in seconds) required for the patient to stand in an erect position from supine (floor). Patients should be barefoot and comfortably clothed.

North Star Ambulatory Assessment score range is 0 to 34, with higher scores indicating better ambulatory function.
At Enrollment visit, and each Yearly Follow-up Visit (for up to 5 years).
Change in Performance of Upper Limb from baseline
Lasso di tempo: At Enrollment Visit, at each Yearly Follow-up Visit (for up to 5 years).

The Performance of Upper Limb assessment is an observer-rated measure of upper-limb function in individuals with Duchenne muscular dystrophy. It includes an entry item to determine the participant's starting functional level and a series of tasks evaluating shoulder, mid-level (elbow), and distal (wrist/hand) abilities. Total scores reflect the participant's ability to perform defined functional movements, with higher scores indicating better function.
At Enrollment Visit, at each Yearly Follow-up Visit (for up to 5 years).
Tanner stage documentation
Lasso di tempo: At Enrollment Visit (baseline), at each Yearly Follow-up Visit (for up to 5 years).
