Last thoughts for the day. Let’s look at this one more time by sentence.
“As you have already seen, the company has announced that they have submitted their application to us.”
(That’s definitely not boilerplate, because they would have to do some checking to see that the company actually announced their application to MHRA)
“We are working activelyon this application, recognising the impact this medicine could potentially have.”
(That’s not boilerplate, because they’d have to check and make certain the application was not rejected or possibly on appeal)
“Finally, please be assured we a[re] progressing this application as rapidly as possible and in collaboration with the company.”
(That’s likely not boilerplate, because there was a typo, and more importantly, they’d have to check that the parties were currently working together as opposed to a rejection or possibly on appeal.)
IMHO.
