When will Zyprexa/Samidorphan be available

The drug name is Alkermes 3831. When will this be available? I’m trying to do so much research on it and cannot find when it will be available

I’ll be the first in line.

When will the new version be availibly in the EU. It is of major importance to me because my 76 old mother goes on and off of her zyprexa because she doesn’t like the weight gaining properties of this meds.
