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.
