E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To perform a detailed clinical and functional characterization and natural history analysis in adult patients with SMA types 2-3-4 with and without nusinersen (Spinraza®) treatment. |
|
E.2.2 | Secondary objectives of the trial |
To assess effectiveness of nusinersen treatment in adult SMA patients. To assess safety of nusinersen treatment in adult SMA patients. To assess natural history in untreated adult SMA patients. To identify biomarkers in blood and cerebrospinal fluid correlated to clinical outcomes in adult SMA patients treated with nusinersen. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
(1) Male or female patients, adult age (18 years or older), with genetically confirmed 5q-related Spinal Muscular Atrophy (SMA) (i.e. deletions of both SMN1-genes or mutations in both SMN1- genes have been proven). (2) Female patients need to use a contraceptive in case they are being treated with nusinersen (Spinraza®) (standard-of-care). (3) Written informed consent. |
|
E.4 | Principal exclusion criteria |
(1) Patients younger than 18 years of age at the time of the study. (2) Patients without genetically confirmed diagnosis of 5q-SMA at the time of the study. (3) No written informed consent. |

E.5 End points |
E.5.1 | Primary end point(s) |
Change in clinical and functional characteristics (*) in adult SMA patients treated with nusinersen from baseline to 22 months.
(*) The clinical and functional characteristics are the following: 6 minute walk distance, grip strength at both hands, general clinical neurological examination, Medical Research Council (MRC) sum score, Hammersmith functional motor scale expanded (HFMSE) with video-acquisition, revised upper limb module (RULM) with video-acquisition, lung function testing in sitting and supine position, the Rasch-built measure of activity limitations scale (ActiVlim), RX full-spine, blood analyses, urine analysis, vital parameters such as blood pressure, pulse, temperature, and the SF-36 quality of life (QoL) questionnaire. |

Number of adult SMA patients that experience adverse events of nusinersen treatment. Decline in clinical and functional measurements in adult SMA patients that have not been treated. Quantitative changes of biomarkers in blood and CSF over time during treatment with nusinersen in adult SMA patients |
