Preg_replace replace specific phrase

I have a description that has two pieces of text I'd like removed and the
text to be formatted. The string can change and have both   and
whitespace in it (it's bad data).
I need to remove both the product name and a block of text at the end
(both of which can change per "product"). I've got the product name stored
as a variable like so:
$prName = "Test CPL560 Home Office Corner Workstation";
And the text from the end that needs removed is as follows:
free delivery5-7 working days  assembly required?Yes
  guarantee2 years  dimensions(mm) Width: 
1600-2340  Depth:  700-1350  Height: 760
Removing the product name should be fairly straightforward but the last
block of text is stumping me as the width, depth etc. can all change on a
product by product basis. Any suggestions?

I'm not bothered about where the paragraphing takes place, only to make it
semi readable. Is this possible via preg_replace or regex?
