Brief Summary:

This study will evaluate whether prolonged oral levosimendan can preserve respiratory function more effectively than placebo, resulting in better patient functionality as measured by the ALSFRS-R scale. In this randomized, double-blind, placebo-controlled, parallel-group, multicenter study, subjects are allocated in a 2:1 ratio to receive either levosimendan (1 -2 mg daily) or placebo for 48 weeks. The primary endpoint is slow vital capacity (SVC) at 12 weeks, with the impact on patient function assessed through 48 weeks, adjusted for patient outcome, using ALSFRS-R (combined assessment of function and survival, CAFS). Other important efficacy measures include time to respiratory events, clinical global impression (CGI), assessment of dyspnea using the Borg scale and sleep scales (Pittsburgh sleep quality index and Epworth sleepiness scale). Patient safety is monitored using conventional methods including adverse events, safety laboratory tests, vital signs and 12-lead EKG. Following screening and baseline visits, patients attend the clinic at 2, 4, 8, 12, 24, 36 and 48 weeks, with telephone assessments conducted at weeks 18, 30 and 42. An end of study visit is performed 14-25 days after the last study treatment administration. The study will be monitored by an independent data and safety monitoring board. A long-term extension study will be available for patients completing the study.

Ages Eligible for Study:	18 Years to 120 Years (Adult, Older Adult)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

• Written or verbal informed consent (IC) for participation in the study
• Male or female subjects with diagnosis of laboratory supported probable, probable or definite ALS according to El Escorial revised criteria. Full electromyogram (EMG) report available consistent with ALS (but not necessarily fulfilling the electrodiagnostic criteria for ALS) from an experienced neurophysiologist
• Able to swallow study treatment capsules, and in the opinion of the investigator, is expected to continue to do so during the study
• Sitting SVC between 60-90% of the predicted value for age, height and sex at screening visit
• Disease duration from symptom onset (defined by first muscle weakness or dysarthria) 12-48 months at the time of visit 1 (baseline)
• Able to perform supine SVC in an adequate and reliable way at screening and baseline visits as judged by the investigator
• Subjects with or without riluzole and/or edaravone. If using riluzole (any daily dose up to 100 mg), the dose must have been stable for at least 4 weeks before the screening visit and should not be changed during the study. If using edaravone, the treatment should have been started at least 4 weeks before the screening visit (at least one 28-day treatment cycle as indicated) and should not be changed during the study. If not on riluzole and/or edaravone, the respective treatments should not be started during the study

Exclusion Criteria:

• Subject in whom other causes of neuromuscular weakness have not been excluded
• Subject with a diagnosis of another neurodegenerative disease (e.g. Parkinson's or Alzheimer's disease)
• Assisted ventilation of any type within 3 months before the screening visit or at screening
• Any use of a diaphragm pacing system (DPS) within 3 months before the screening visit
• Any form of stem cell or gene therapy for the treatment of ALS
• Known hypersensitivity to levosimendan
• Administration of levosimendan within 3 months before the screening visit or previous participation in the present phase III study or earlier study with oral levosimendan in ALS patients (LEVALS)
• Any use of tirasemtiv or reldesemtiv within 1 month before the screening visit.
• Participation in a clinical trial with any experimental treatment within 30 days or within 5 half-lives of that treatment (whichever is longer) before the screening visit
• Any botulinum toxin use within 3 months before the screening visit
• Recorded diagnosis or evidence of major psychiatric diagnosis, significant cognitive impairment or clinically evident dementia that may interfere with the patient's ability to comply with study procedures

• History of second or third degree atrioventricular (AV) block or sinus node disease at screening, if not treated with pacemaker
• HR repeatedly > 100 bpm in the 12-lead ECG after a 5-minute rest at screening. If the HR is > 100 bpm in the first recording, then the second recording must be done after another 5 min rest to confirm HR > 100 bpm
• Systolic blood pressure (SBP) < 90 mmHg at screening
• Potassium < 3.7 mmol/l or > 5.5 mmol/l at screening
