Results of Phase 3 Trial of TUDCA in Slowing ALS Likely Next Year

An ongoing Phase 3 clinical trial in Europe is testing whether tauroursodeoxycholic acid, added to standard therapy, can slow disease progression and extend survival among people with amyotrophic lateral sclerosis (ALS). The oral compound, also known as TUDCA, is one of the two ingredients in Relyvrio (sodium phenylbutyrate…

Study Reveals How Growing Motor Neurons Guide Blood Vessel Growth

An international team of researchers discovered how, during development, motor neurons — the nerve cells controlling movement whose death causes amyotrophic lateral sclerosis (ALS) — direct blood vessel growth around them while growing toward target muscles. Specifically, motor neurons were found to secrete a combination of signaling molecules that…

PARADIGM Trial for PrimeC Set to Enroll Soon in US, Italy

NeuroSense Therapeutics has received the go-ahead to begin enrolling patients in the U.S. and Italy for a Phase 2b clinical trial testing PrimeC, the company’s experimental therapy for amyotrophic lateral sclerosis (ALS). The clinical trial, called PARADIGM (NCT05357950), enrolled its first participant in June. The study is…

FDA Declines to Consider Approving NurOwn to Treat ALS

The U.S. Food and Drug Administration (FDA) notified Brainstorm Cell Therapeutics that it will not accept for review a company application asking that its cell-based therapy NurOwn be approved as a treatment for amyotrophic lateral sclerosis (ALS). The FDA decision, in the form of a refusal to file…

New Study Uncovers Mechanism of CuATSM, ALS Therapy Now in Trials

CuATSM, a potential amyotrophic lateral sclerosis (ALS) therapy that’s now in clinical trials, may work by altering how certain cells in the brain generate energy, a new study suggests. Researchers say these findings may help to identify patients most likely to respond to the experimental treatment. “Screening patient derived…

Air Pollution Exposure Tied to Greater ALS Risk in Women in Study

Higher long-term exposure to certain forms of air pollution — specifically coarse particulate matter, such as that from traffic pollutants — significantly increases the risk of amyotrophic lateral sclerosis (ALS) in postmenopausal women, a study showed. “Although the effects noted within the current study are limited by sample size…

Machine Learning May Help Predict ALS Progression

Deep machine-learning models using neural networks — computer algorithms inspired in the biological networks of the human brain —may help to predict the course of amyotrophic lateral sclerosis (ALS), a new study reports. The models also consistently showed that a longer delay between disease onset and diagnosis is a…
