The company, which is developing seven products targeting brain diseases, saw shares (NASDAQ:NMRA) close 4.4% downward at $16.25 on Sept. 15.

Neumora Therapeutics Inc., a neuroscience startup aiming to launch precision medicines for brain diseases, said Oct. 7 it has raised more than $500 million, including a $100 million equity investment from Amgen Inc. and a series A financing led by Arch Venture Partners. The company launches with a portfolio of eight clinical, preclinical and discovery-stage programs from internal discovery efforts, the acquisitions of multiple private companies and a new license agreement with Amgen.
