BenevolentAI S.A. announces the successful delivery of its pre-clinical candidate for the potential treatment of amyotrophic lateral sclerosis (ALS), BEN-34712. BEN-34712 is an oral, potent and selective brain penetrant RAR?ß (retinoic acid receptor alpha beta) biased agonist and will now enter investigational new drug (IND)-enabling studies. Impaired retinoic acid signalling has been shown to result in neuroinflammation, oxidative stress and mitochondrial dysfunction, all hallmarks of ALS.

In preclinical studies conducted by the Company, BEN-34712 was neuroprotective in a patient-derived, disease-relevant in vitro motor neuron/iAstrocyte co-culture model, demonstrating significant efficacy in both sporadic and familial subtypes of ALS. In addition, BEN-34712 has demonstrated both central nervous system (CNS) target engagement and functional protective effects in the SOD1G93A mouse model of ALS after 50-day repeat dosing. BenevolentAI collaborated with the Sheffield Institute for Translational Neuroscience (SITraN) at the University of Sheffield on this programme, utilising their patient-derived motor neuron/iAstrocyte co-culture systems and in vivo model expertise.
