Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 20 years and older
- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Patients who have completed Phase II/III study of E0302 (E0302-J081-761, hereafter referred to as Study 761) except for those patients who discontinued the treatment of Study 761. Completed patients are defined as those who completed the treatment period of Study 761, those on 24-hour use of non-invasive positive pressure ventilation (NIPPV), or those who eventually resulted in the use of NIPPV.
- Patients who are able to submit written informed consent. If patients are duly capable of study consent but are unable to sign (or affix a seal) by themselves due to aggravation of disease condition, written informed consent can be obtained from a legally authorized representative who can sign on behalf of the patients after confirming the patients' agreement to study participation.
Who cannot join
- Patients with cognitive impairment.
- Pregnant women or women who may have a possibility of becoming pregnant.
- Patients or their partners who are not willing to use reliable contraception.
- Patients with severe disease in the renal, cardiovascular, hematological, or hepatic system (severe disease will be judged referring to "Ministry of Health, Labor and Welfare (MHLW) Drug Safety Dept. Notification No. 80, Drug Safety Classification Criteria for Severity of Adverse Drug Reaction by Medicinal Products, Grade 3." However, an event due to the primary disease will be precluded).
- Patients with malignant tumor.
- Patients who participated in another clinical study after the completion of Study 761.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing E0302 (mecobalamin) in people with Amyotrophic Lateral Sclerosis (ALS), run by Eisai Co., Ltd. at 42 sites in Japan.
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 2 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: finished, as of the sponsor's last update on 18 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 42 sites in Japan. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Number of participants with Adverse Events as a Measure of safety (time frame: Every 3 months). 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 NCT00445172, 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 18 Jun 2023.
