Development & testing of the ‘CLP’ molecule series for normalizing inhibition in different disorders (chronic pain, autism, epilepsy, etc)

Mapplebeck JCS, Lorenzo LE, Lee KY, Gauthier C, Muley MM, De Koninck Y, Prescott SA, Salter MW. Chloride Dysregulation through Downregulation of KCC2 Mediates Neuropathic Pain in Both Sexes. Cell Rep. 2019 Jul 16;28(3):590-596.e4.

Ferrini F, Lorenzo LE, Godin AG, Quang ML, De Koninck Y. Enhancing KCC2 function counteracts morphine-induced hyperalgesia. Sci Rep. 2017 Jun 20;7(1):3870.

It can also be noted that a partnership was developed with Hofmann-La Roche (2013-2015) to improve potency and bioavailability of the best CLP molecules candidates for indications such as autism and pain.

The CNP has also initated discussions with SOVAR ( for the promotion of CLP molecules (November 2019).
