A few questions if anyone can help with, Thanks!

The pipeline update for Addex has:

Pipeline Update
Dipraglurant ( mGluR5NAM ):

Is that the same as
metabotropic glutamate receptor 5 ( mGluR5 ) ?

If so, it's interesting that Dr. Keywood & Mark Wakefield are two of the four inventors of that.

Inventors:
Charlotte KEYWOOD , Sonia Maria Poli, Mark Wakefield , Mohamad Haitham Ayad

Did they just walk away from it? And do they still have Patent rights to it?

Again, if any one knows, any clarification would help. Thanks.

Cheers
