Circuit Therapeutics's Overview

Total employees30
HeadquartersMenlo Park
Founded2010

Circuit Therapeutics was a pioneering biotechnology company focused on developing novel therapies for neurological and psychiatric diseases using optogenetics, a cutting-edge technology that employs light to control nerve cells with high precision. Founded in 2010, the company aimed to translate advanced neuroscience research into targeted and effective treatments for conditions with significant unmet medical needs. In July 2021, Circuit Therapeutics was acquired by Merck & Co., Inc. (known as MSD outside the United States and Canada), with the goal of integrating Circuit's innovative neuromodulation platform into Merck's broader research and development efforts in neuroscience.

Where is Circuit Therapeutics's Headquarters?
