very well said Kelt
Term sheet is indicating pathophysiology ( reason) for condition covered by agreement and the anatomical location(IBD vs OM)
OM is inflammatory/ infectious condition related to specific form of treatment ( chemo or chemo-radiation or idiopathic ( no reason) occurring in mouth mucosa ....the most common location of mucositis.
This condition can occur not only in the mouth but also in any portion of the bowel ( large or small) for other reasons eg chemo induced or infectious.
Our management , I am sure of it is looking to have a separate term sheet sign for B-OM .
In case of IBD..(UC and Crohn) has different pathophysiology ( auto-immune) and they differ from each other.
UC ( Ulcerative colitis) mainly affects large bowel and Crohns can affect entire GI mucosa from anus to mouth.
So B can be use to treat different conditions with different pathophysiology and different locations.
Leo not once mentioned that he wants to follow REGN and will be looking for separate multi-million $ deals for B for different indications .
my opinion only
