About this study
Official title: Effects of Oral Levosimendan (ODM-109) on Respiratory Function in Patients With ALS: Open-Label Extension for Patients Completing Study 3119002
This study provides an opportunity for subjects in the REFALS (3119002; NCT03505021) study to continue treatment with oral levosimendan. The study will also provide more information about long-term safety and effectiveness of oral levosimendan in patients with ALS.
This is an open-label study, so that all eligible subjects that complete the double-blind REFALS study (48-weeks of treatment) will have the opportunity to receive oral levosimendan treatment. The primary objective, in addition to continuing treatment for subjects enrolled in the REFALS study, is to evaluate long-term safety of oral levosimendan in ALS patients. Another important objective is to explore long-term effectiveness of oral levosimendan in the treatment of patients with ALS.
This study is open only to patients taking part in the REFALS study.

- Amyotrophic Lateral Sclerosis

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
LevosimendanDrug
Also called ODM-109
Levosimendan 1 mg capsule for oral administration
| Study group | Role | What they receive |
|---|---|---|
| Levosimendan | Experimental | Oral Levosimendan; Levosimendan 1mg capsules for oral administration, once to twice a day, continued as long as clinically beneficial. The total study duration is up to 3 years. Receives: Drug: Levosimendan |
What is being measured
The primary outcome is the main question the study is designed to answer.
Adverse Events Recording
Adverse Events as subject counts and proportions (%) of subject per Adverse Event
Measured: From signing informed consent until 14-25 days after the last study treatment for all patients, an average of 23.5 weeks.
Pulse/Heart Rate Assessment
Actual values and changes from baseline in supine pre-dose pulse/heart rate were summarised using descriptive statistics .
Measured: Change in pulse and heart rate(from ECG recording) from Baseline, week 2, week 4, week 6 (pulse rate only), Month 3, Month 6, end of study (subject's last visit, 2-48 weeks after study entry)
12-lead Electrocardiogram Assessments
Summarisation of any abnormal 12-lead ECG findings using descriptive statistics.
Measured: Baseline, week 2, week 4, month 3, month 6, end-of-study(subject's last visit, 2-48 weeks after study entry)
Secondary outcomes (10)
Disease Progression
Count of study withdrawals due to disease progression
Measured: From Baseline through study completion(subject's last visit, 2-48 weeks after study entry)
Supine Slow Vital Capacity (SVC)
Change from baseline in supine and sitting SVC (all devices) through to the end of the study, expressed as a % of predicted normal
Measured: The change from Baseline, week 2, week 4, month 3, month 6, end-of-study (subject's last visit, 2-48 weeks after study entry)
Revised ALS Functional Rating Scale (ALSFRS-R)
ALSFRS-R scale contains 3 parameters related to respiratory function: Severity of dyspnea, occurrence of orthopnea (shortness of breath when in supine position i.e. lying flat), and the use of mechanical ventilation for respiratory in sufficiency. These 3 parameters are combined to create the respiratory domain with a score of 0-12(where 12 is normal function). Although individual items and patients vary, ALSFRS-R typically declines at a relatively constant rate over time. Plotted over time the slope of the line obtained indicates the speed of progression and thus an effective treatment might be expected ro reduce the slope of decline.
Measured: Change from Baseline in respiratory function of ALSFRS-R at study completion (subject's last visit, 2-48 weeks after study entry)
Need for Respiratory Support Device
Time to respiratory device support (non invasive) or death
Measured: Time to event at study completion (subject's last visit, 2-48 weeks after study entry)
Borg Category Ratio 10 Scale (CR 10)
Patients rated their perception of the severity of their dyspnea using the Borg Category Ration 10 scale (CR 10). The scale ranges from 0(no dysponea) to 10 (maximal dyspnea). each category is numbered and most but not all have verbal cues. At each assessment the patient scored the category they felt best described their symptoms. The analysis measured change from baseline to the end of the study in both a supine and sitting position where a negative score indicates improvement and a positive score reflects worsening.
Measured: Baseline through study completion (week 2, week 4, month 3, month 6, end of study (subject's last visit, 2-48 weeks after study entry)
Number of Subjects Requiring Health and Home Care Resource Use
The number of study subjects requiring Health and home care resource use was aggregated over the course of the study for each subject and summarised using descriptive statistics.
Measured: Baseline through study completion (2- 48 weeks after study entry)
Subject's Status for Tracheostomy and Survival
Number of patients with the need for tracheostomy or who died whilst on treatment from baseline to the end of the study was summarised using descriptive statistics.
Measured: Baseline to end of study (average 2-48 weeks after study entry
Health Care Service Use During the Study(Stays in Hospital)
The number of night stays in hospital were recorded throughout the study using a diary given to the study subjects
Measured: From baseline to the end of the study(2-48 weeks after study entry)
Health Care Service Use During the Study(Visits to the Emergency Room)
The number of visits to the emergency room were recorded throughout the study using a diary given to the study subjects
Measured: From baseline to the end of the study(2-48 weeks after study entry)
Health Care Service Use During the Study (Days Spent in an Institutional Facility)
The number of days spent in an institutional facility were recorded throughout the study using a diary given to the study subjects
Measured: From baseline to the end of the study(2-48 weeks after study entry)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Levosimendan in people with Amyotrophic Lateral Sclerosis, run by Orion Corporation, Orion Pharma at 79 sites in 14 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 9 Mar 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 79 sites in United States, Canada, Germany, Italy, Australia and 9 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 9 Mar 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Adverse Events Recording (time frame: From signing informed consent until 14-25 days after the last study treatment for all patients, an average of 23.5 weeks.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03948178, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2023.
