Brainstorm-Cell Therapeutics
Summary
The goal of this two-part clinical trial is: 1\) 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. 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.
