Respiratory support with mobilization of secretions and use of non-invasive ventilation play an important role in the management of children with SMA, to prevent chest infections and promote thoracic development and compliance. Agneta Markstrom presented an overview of respiratory care during our LISN and LERN meeting in 2019.
The pubexplainer is a short animated video made by Biogen which summarizes the key findings and conclusions in Hagenacker et al. 2020 (Lancet Neurology). This study is the largest efficacy and safety study of nusinersen in the most diverse SMA adult population studied to date.
This video shows an expert interview with Dr. Tim Hagenacker, Chief Senior Physician of the Clinic for Neurology, Essen University Hospital.
This video shows an expert interview with Prof. Christoph Kleinschnitz, Director of the Clinic for Neurology, Essen University Hospital. In this video Prof. Kleinschnitz talks about what conclusions doctors involved in SMA diagnostics should draw from the study results.
This presentation was hosted by Anna-Karin Kroksmark during 2020's Listen & Learn meeting. It was a break-out session intended for physiotherapists on habilitation and rehabilitation in SMA.
This presentation was hosted by Anna-Karin Kroksmark during 2020's Listen & Learn meeting. It was a the opening session of 2020's Listen & Learn meeting and was about outcome measures.
This presentation was done by Mar Tulinius and Christopher Lindberg during 2020's Listen & Learn meeting. They shared their perspectives on the paediatric-adult transition process in SMA from their respective centres in Gothenburg.
Patients with profound hypotonia and respiratory failure at birth, a setting in which Spinraza has not been studied, may not experience a clinically meaningful benefit due to severe SMN protein deficiency. There is a risk of adverse reactions occurring as part of the lumbar puncture (e.g headache, back pain, vomiting; see section 4.8 in the SPC. Potential difficulties with the route of administration may be seen in very young patients and those with scoliosis. The use of ultrasound or other imaging techniques to assist with intrathecal administration of Spinraza can be considered at the physicians discretion.
Renal toxicity has been observed after administration of other subcutaneously and intravenously administered antisense nucleotides. If clinically indicated, urine protein testing (preferably using a first morning urine specimen) is recommended. For persistent elevated urinary protein, further evaluation should be considered.
Thrombocytopenia, coagulation abnormalities, including acute severe thrombocytopenia and renal toxicity have been observed after administration of other subcutaneously or intravenously administered antisense oligonucleotides. If clinically indicated, laboratory testing of platelet, coagulation and urine protein is recommended prior to administration of Spinraza.
There have been reports of communicating hydrocephalus not related to meningitis or bleeding in patients treated with nusinersen in the post-marketing setting. See section 4.4 in the SPC (01/2021) for further details.
