Effects of oral levosimendan (ODM-109) on respiratory function in patients with ALS

Purpose: 

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

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

Pulmonary illness (e.g. asthma or COPD) requiring regular treatment

Haemodynamically significant uncorrected valve disease or hypertrophic cardiomyopathy or restrictive cardiomyopathy

Any cardiovascular event (e.g. myocardial infarction, HF, arrhythmia or stroke) requiring hospitalisation within 3 months before the screening visit

History of Torsades de Pointes (TdP) or diagnosed long QT-syndrome

History of life-threatening ventricular arrhythmia, unless treated with reliable measures to prevent recurrence (e.g. with placement of implantable cardioverter defibrillator [ICD] or catheter ablation)

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

Severe renal impairment (creatinine clearance < 30 ml/min at screening), creatinine > 170 μmol/l at screening or on dialysis

Blood haemoglobin < 10 g/dl at screening or blood donation or loss of significant amount of blood within 60 days before the screening visit

Clinically significant hepatic impairment at the discretion of the investigator

Body mass index (BMI) ≤ 18.5kg/m2 (BMI = weight/height2)

Women who are lactating or of reproductive age without a negative pregnancy test and without a commitment to using a highly effective method of contraception (e.g. oral hormonal contraceptives associated with inhibition of ovulation, intrauterine devices and long acting progestin agents), if sexually active during the study, and for 1 month after the last dose of the study treatment. Women who are postmenopausal (1 year since last menstrual cycle), surgically sterilised or who have undergone a hysterectomy are considered not to be reproductive and can be included

Patient judged to be actively suicidal by the investigator during 3 months before the screening visit

Patients with known history of human immunodeficiency virus (HIV) infection

Any other clinically significant cardiovascular, gastrointestinal, hepatic, renal, neurological or psychiatric disorder or any other major concurrent illness that in the opinion of the investigator could interfere with the interpretation of the study results or constitute a health risk for the subject if he/she took part in the study
