Más betegség

Laborértékek

• Any clinically significant and/or unstable medical (including active systemic infections requiring treatment), surgical, or psychiatric condition or laboratory abnormality other than ALS, in the judgement of the Investigator.

• Significant renal impairment as determined by estimated glomerular filtration rate (eGFR) of <60 mL/min.
• Clinically significant history of cardiac function impairment including cardiac ejection fraction below 40%, ventricular wall motion abnormalities, or coronary artery disease.

Életkor

• Pre-existing chronic obstructive pulmonary disease or significant pulmonary impairment including those with an FEV1 ≤ 2 liters or < 75% predicted for height and age, in the judgement of the Investigator.

Egyéb

• Active suicidality (e.g., any suicide attempts within the past 12 months or any current suicidal intent, including a plan, as assessed by the C-SSRS, score of "YES" on questions 4 or 5; and/or based on clinical evaluation by the Investigator).
• Any organ allografts.
• Presence of an indwelling central catheter.
  • NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.

• Sporadic or familial ALS, diagnosed as clinically probable, lab-supported probable, or definite ALS according to the revised El Escorial criteria
• Male or female participants aged 18 to 80
• Time since onset of ALS symptoms ≤28 months from Screening.

• SVC ≥60% of predicted capacity.
• Participants receiving riluzole must be on a stable dose for at least 30 days prior to Screening, with intent to stay on stable dosage throughout the study. If not on a stable dose of riluzole for at least 30 days prior to Screening, willing to refrain from initiation of the agent for the duration of the trial.
• Participants receiving edaravone (intravenous [IV] or oral, RADICAVA®) must have completed at least one treatment cycle prior to Screening, with intent to remain on stable dosage throughout the study. If participant has not completed at least one treatment cycle of edaravone at the time of Screening, willing to refrain from initiation of the agent for the duration of the trial.
• Participants receiving tofersen (QALSODY®) must have completed 90 days of treatment prior to Screening, with intent to remain on stable dosage throughout the study. If participant has not completed at least 90 days of tofersen at the time of Screening, willing to refrain from initiation of the agent for the duration of the trial.
