As developers continue to search for better amyotrophic lateral sclerosis (ALS) therapies, Neurosense Therapeutics Ltd. turned up some hopeful findings from its phase IIb Paradigm trial with PrimeC. The drug, a combination therapy (ciprofloxacin and celecoxib) designed to target multiple ALS pathways, is having salutary effects on microRNA modulation (miRNA), Neurosense said, with the study showing a “profound and consistent” downregulation of 161 mature miRNAs across all time points in the double-blind period of the experiment.

Voyager Therapeutics Inc. has announced its decision to assess alternate payloads related to its gene therapy program for superoxide dismutase 1 (SOD1) amyotrophic lateral sclerosis (ALS). Emerging preclinical data indicate the siRNA payload component of VY-9323 does not meet its standards due to what appears to be an off-target effect resulting in a narrowed therapeutic window.
