It is very boring and is due to be altered (7)
I believe the answer is:
tedious
'it is very boring' is the definition.
(I've seen this in another clue)
'is due to be altered' is the wordplay.
'be altered' is an anagram indicator.
'is'+'due'+'to'='isdueto'
'isdueto' with letters rearranged gives 'TEDIOUS'.
'and' acts as a link.
(Other definitions for tedious that I've seen before include "not worth listening to?" , "Long, slow, dull" , "not exciting" , "Wearisome, boring" , "awfully boring" .)
