Result substring should be : Message(with some tricky word)

How can i get only "Message(with some tricky word)" from the Line "This is the TEST(Message(with some tricky word)) from which i want to search." ?

I cant format a RegExp for this kind of search. Please help me to format such tricky Regular Expression with some useful commands .Thanks in advance.

EXAMPLE ::
The input string will be like this :

This is another example where TEST( string is going to be (after TEST everytime ) and it will be in the (braces all the time like this ) so this clears my requirements. ) ;

Result should be :

string is going to be (after TEST everytime )

There will be more variety in terms of braces but the string to be searched will always be after TEST and in the braces starts immediately after TEST upto the end of that brace only.
