Removing a set of unwanted characters from a column

Hi All

I am trying to remove some superfluous text from a list of names.

ie.
current: John Brown (AUS), Joe Bloggs (NZ), Sue Smith nz., Ruby Red New Zealand
desired: John Brown, Joe Bloggs, Sue Smith, Ruby Red.

In column E of the sample list, ive tried to account for all of these possibilities.

The list of text to remove is quite long (longer than the sample in column E), so i was hoping there was a formula(s) or macro that would assist me rather that having to individually 'Find & Replace'.

If anyone can assist, that would be great.

Thanks!
