RegEx | Komodo Edit - Remove duplicate search strings

Question

Note that this has been asked alot before but there was no answer which worked properly. Better if you try it yourself with the provided example.

The wanted RegEx is to remove duplicate strings using Komodo Edit Replace tool.

Example: The following text(Note: with , i mean newline) -

ALL_1397 , ALL_1398 , A_1000 , A_1100 , ALL_1397 , A_1397 , A_1100 ,

When searching for ALL_*(Matches any character) and replacing should result in -

ALL_1397 , ALL_1398 , A_1000 , A_1100 , , A_1397 , A_1100 ,

Also it should not require replacing each string alone. Replace All must work.
