Paul Matteis's questions to Neumora Therapeutics (NMRA) leadership • Q2 2025
Question
An analyst on behalf of Paul Matteis questioned the company's confidence in the safety profile of the M4 PAM NMRA-861, specifically in contrast to the previously halted NMRA-266 molecule from the same Vanderbilt deal.
Answer
Joshua Pinto, President, and Nicholas Brandon, Chief Scientific Officer, addressed the question. Pinto emphasized that all M4 PAM compounds (NMRA-861, NMRA-898, and the prior NMRA-266) are structurally distinct. Brandon added that the key safety hurdle was the unexpected convulsions seen in rabbits with NMRA-266. He stated that both NMRA-861 and NMRA-898 have been tested in rabbits at doses and exposures exceeding where issues occurred with NMRA-266, with no convulsions observed, thereby de-risking the new molecules.
