About this study
Official title: A Two-Part Phase 3b Randomized, Double-Blind, Placebo-Controlled, Followed by Open-Label Extension, Multicenter Study of the Efficacy and Safety of MSC-NTF (NurOwn) in Participants With With Early Symptomatic and Moderate Disease Presentation in Amyotrophic Lateral Sclerosis (ALS)
The goal of this two-part clinical trial is:
- to evaluate the safety and efficacy of Debamestrocel - MSC-NTF (NurOwn) compared to placebo in participants with early symptomatic ALS and moderate disease presentation in ALS; followed by 2) further evaluation by providing NurOwn to all participants in an open label extension period.
Read more
Researchers will compare NurOwn to a placebo (a look-alike substance that contains no drug) to evaluate the efficacy of NurOwn compared to placebo in the treatment of participants with ALS.
Participants will:
Receive NurOwn or a placebo every 8 weeks for 24 weeks. After that, every participant will receive NurOwn every 8 weeks for an additional 24 weeks.
They will visit the clinic approximately every 8 weeks for checkups and tests.
Read the detailed description
This is a multicenter, Phase 3b study to assess the efficacy and safety of NurOwn in participants with early symptomatic ALS and moderate disease presentation in ALS. The study comprises two parts: a 24-week randomized, double blind placebo controlled period (Part A) followed by a 24-week open label expansion period (Part B).
Up to approximately 200 participants are planned to be enrolled and randomized 1:1 to the NurOwn and placebo groups in Part A. All eligible participants who complete Part A will have the option of entering Part B.
The trial includes a 9-week screening period. After the first screening visit (Screening Visit 1), there will be a Screening Visit 2, during which randomization 1:1 to the NurOwn and placebo groups will occur after confirming that all entry criteria are met. Following randomization, bone marrow aspiration will be scheduled. Stem cells from the bone marrow of all participants will be isolated, and then cryopreserved. Prior to each intrathecal (IT) dose administration, cells will be thawed, propagated, and induced into MSC-NTF cells (NurOwn).
In Part A, participants will receive NurOwn or placebo via IT injection every eight weeks at Weeks 0, 8, and 16.
In Part B, participants will receive NurOwn via IT injection every eight weeks at Weeks 24, 32, and 40.
All participants will be offered the option to participate in the collection and storage of blood/serum, CSF, and buccal samples for future analysis of biomarkers and genetic testing.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in the ALSFRS-R total score from baseline to Week 24
To evaluate the efficacy of NurOwn compared to placebo in the treatment of participants with ALS based on the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) which is a 12-item clinician-administered questionnaire. Each item is scored between 0 and 4, with the total ALSFRS-R score between 0 and 48 where a higher score reflects a better outcome.
Measured: From baseline to Week 24
Frequency and severity of adverse events including treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), death, abnormalities in laboratory evaluations, physical examinations, vital signs and electrocardiogram (ECG) assessments
To evaluate the safety and tolerability of NurOwn in the treatment of participants with ALS throughout the study including the DBPC period (Part A) to Week 24 and the Open Label Extension (Part B).
Measured: From baseline to Week 48
Secondary outcomes (2)
Change in SVC (%predicted) from baseline to Week 24
To evaluate the efficacy of NurOwn compared to placebo on respiratory function based on slow vital capacity (SVC)
Measured: From baseline to Week 24
Change in HHD from baseline to Week 24
To evaluate the efficacy of NurOwn compared to placebo on upper limb muscle strength based on the hand-held dynamometry (HHD) measurement
Measured: From baseline to Week 24

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Debamestrocel - MSC-NTF (NurOwn) in people with Amyotrophic Lateral Sclerosis (ALS) and Amyotrophic Lateral Sclerosis, run by Brainstorm-Cell Therapeutics at 15 sites in United States.
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 7 inclusion and 9 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: opening soon, as of the sponsor's last update on 22 May 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 15 sites in United States. 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. Some participants in this study may receive a placebo. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Chief Medical Officer, Brainstorm Cell Therapeutics, MD (201-488-0460, ClinicalTrial@Brainstorm-cell.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in the ALSFRS-R total score from baseline to Week 24 (time frame: From baseline to Week 24). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 22 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
