Más betegség

Egyéb

• Have participated or currently participating in another clinical trial within 5 half-lives of baseline (Day 1)
• Have undergone a tracheostomy for ALS symptoms
• Are on nasal intermittent positive pressure ventilation (NIPPV) >4 hours per day for the treatment of ALS related symptoms
• Have other causes of neuromuscular weakness
• Pregnant or nursing women
• Have been exposed to any antisense treatment targeting SOD1 within 6 months of the baseline visit

• All participants must adhere to contraception restrictions
• Female participants of childbearing potential must adhere to contraception restrictions
• Have possible, clinically probable, clinically probable-laboratory supported or definite familial or sporadic ALS in accordance with the El-Escorial criteria or who have a diagnosis of ALS as defined by the Gold Coast Criteria; progressive motor impairment documented by history or repeated clinical examination, preceded by normal motor development, and presence of upper and lower motor neuron dysfunction in at least 1 body region or lower motor neuron dysfunction in at least 2 body regions and investigations excluding other conditions
• In familial ALS participants, a confirmed pathogenic superoxide dismutase 1 (SOD1) mutation
• Onset of symptoms (i.e, weakness) within past 24 months prior to screening, at the time of obtaining informed consent
• Have slow vital capacity (SVC) of greater than or equal to (> or =) 50 percentage (%) of predicted values. Participants with SVC of <50% of predicted values may be permitted to enter the open-label extension, based on the opinion of the investigator
• Absence of bilevel positive airway pressure (BiPAP)/proportional assist ventilation (PAV) > 4 hours for symptoms attributable to ALS. Use of a CPAP for pre-existing conditions will be allowed

• Able to provide informed consent which includes compliance with the requirements and restrictions
• Have venous access sufficient to allow for blood sampling
• Have clinical laboratory test results within the normal reference range for the population or study site, or results with acceptable deviations that are judged to be not clinically significant by the investigator
