Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants who are receiving or about to initiate treatment with commercial Spinraza in Korea according to the local marketing authorization (including documentation of SMA diagnosis), agree to the collection and use of data as specified in the protocol, and meet the eligibility criteria.

Description

Key Inclusion Criteria:

  • Currently receiving or about to initiate treatment with commercial Spinraza in the postmarketing setting
  • Genetic documentation of 5q-linked SMA

Key Exclusion Criteria:

  • Hypersensitivity to the active substance or any of the excipients of Spinraza
  • Ongoing participation or participation within 6 months or 5 half-lives of the agent (whichever is longer) of enrollment in other interventional clinical trials for the treatment of SMA
  • Inability to comply with study requirements

NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)
Time Frame: Up to End of Treatment (2 Years)
An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose results in death, places the participant at immediate risk of death, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, results in a congenital anomaly/birth defect, or is a medically important event.
Up to End of Treatment (2 Years)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Hammersmith Infant Neurological Examination (HINE) Section 2 Scores
Time Frame: Baseline, Day 63 and Approximately Every 4 Months Up to End of Treatment (2 years)
Section 2 of the HINE is used to assess motor milestones of the participants. It is composed of 8 motor milestone categories: voluntary grasp, ability to kick in supine position, head control, rolling, sitting, crawling, standing, and walking.
Baseline, Day 63 and Approximately Every 4 Months Up to End of Treatment (2 years)
Change from Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE)
Time Frame: Baseline, Day 63 and Approximately Every 4 Months Up to End of Treatment (2 years)
The HFMSE is a tool used to assess motor function in children with SMA. The original 20 item Hammersmith Functional Motor Scale (HFMS) was expanded to include 13 additional items to improve sensitivity for the higher functioning ambulant population. Participants are asked to complete a specific movement and are then graded on the quality and execution of that movement. Higher scores indicate higher levels of motor ability where 0=unable, 1=performed with some assistance, and 2=unaided. The overall score is the sum of the scores for all activities.
Baseline, Day 63 and Approximately Every 4 Months Up to End of Treatment (2 years)
Time to Death
Time Frame: Up to End of Treatment (2 years)
Up to End of Treatment (2 years)
Number of Participants with Ventilatory Support
Time Frame: Up to End of Treatment (2 years)
